FIELD OF THE INVENTION

[0002] The present disclosure relates to compositions and methods comprising an epigenetic agent and a Wnt agonist for increasing proliferation of cochlear supporting cells or vestibular supporting cells, production of an expanded population of cochlear or vestibular cells, in particular Lgr5+ cells, and related methods of treating an inner hearing or balance disorder, in particular sensorineural hearing loss.

BACKGROUND OF THE INVENTION

[0003] Generation of sensory hair cells from undifferentiated cell populations is likely to provide a therapy for several inner ear hearing and balance disorders that arise from damage and loss of sensory hair cells in the inner ear. Replacement hair cells could be produced in situ, in the damaged sensory epithelium of the inner ear, or grown in vitro and then delivered to the inner ear, and so strategies for generation of sensory cells in vitro and in vivo are of interest.

[0004] Sensorineural hearing loss (SNHL), which is largely due to the loss of sensory hair cells and their neural connections is a widespread problem. It is estimated that over one billion young people are at risk for noise-related sensorineural hearing loss. SNHL accounts for about include advanced age, ototoxic medications, and noise exposure (Liberman & Kujawa, Hear.

Res. 349, 138‒147, 2017). The majority of children and adults with SNHL are managed with hearing aids or cochlear implants, as there is currently no therapeutic option to restore function in the damaged inner ear (see, for example, Ramakers et al., Laryngoscope 125, 2584‒92, 2015; Raman et al., Effectiveness of Cochlear Implants in Adults with Sensorineural Hearing Loss. Agency for Healthcare Research and Quality (US), 2011; and Roche & Hansen, Otolaryngol. Clin. North Am. 48, 1097‒116, 2015). Loss or damage of hair cells in the vestibular system of inner ear can lead to balance disorders (for example, dizziness and vertigo), incidences of which also increase with age. Like the cochlea, there is currently no therapeutic option to restore function in damaged vestibular epithelia, and regeneration of hair cells may also be an effective therapeutic approach for balance disorders.

[0005] The underlying pathophysiologic changes of sensory epithelia of the inner ear in patients with inner ear hearing loss or balance disorders includes damage and loss of sensory transducers of the cochl ear and vestibular systems called hair cells. Hair cells are susceptible to damage, and although other species such as birds, fish, and amphibians can regenerate these cells throughout life, mammals lack this ability (Fujioka et al., Trends Neuroses. 38, 139‒44, 2015).

[0006] Several approaches are being investigated to replace damaged or absent hair cells in mammalian inner ear sensory epithelia (reviewed in Mittal et al. Front Mol Neuroses. (2017); 10: 236). These include cell-based approaches (which aim to deliver exogenous cells to the inner ear to restore the sensory epithelia) and gene-based approaches (which aim to deliver exogenous genes to the sensory epithelia and reprogram endogenous cells to generate hair cells). For example, adenovirus-mediated delivery of Atoh1 is able to stimulate cells within the sensory epithelia to differentiate into hair cells (Izumikawa et al. Nat Med. 2005 Mar;11(3):271-6. Epub 2005 Feb 13). One drawback with these approaches is the requirement to deliver cells or vectors into the inner of the patient, which can be challenging in the complex system of the inner ear. Molecular approaches, in which the endogenous signaling pathways of inner ear cells are modulated by exogenous agents are therefore attractive, as the delivery of such agents for prolonged periods of time is likely to be more straightforward than cell-based or gene-based approaches.

[0007] Using molecular agents to initiate transdifferentiation, in which existing supporting cells of the cochlear are stimulated to differentiate into replacement hair cells, is one area of interest. However, transdifferentiation alone (i.e. without proliferation) may not provide sufficient hair cells to regenerate a functioning cochlea or vestibular system, especially as an associated depletion of the supporting cell population could also negatively impact the functioning of the cochlea or vestibular organs. Focus has therefore been placed on activation of proliferative response in the supporting cells, in order to provide a new population of cells that could differentiate into hair cells, thereby replacing lost or damaged hair cells.

[0008] A subset of supporting cells that express Lgr5 have been shown to be endogenous hair cell progenitors with stimulation via the Wnt/beta-catenin pathway leading to proliferation and differentiation of these cells into sensory hair cells (Bramhall et al. 2014 Stem Cell Repotrs 2, 311‒322). More recently, a combination of a Wnt pathway agonist (a GSK3β inhibitor) in combination with a histone deacetylase complex (HDAC) inhibitor has been found to stimulate expansion of an Lgr5+ supporting cell population in the inner ear and regenrate hair cells ex vivo (McLean et al. Cell Rep. 2017 February 21; 18(8): 1917‒1929).

[0009] There remains a need for the development of effective hair cell regeneration strategies in the inner ear, in vivo, which may include boosting the proliferation of supporting cells of sensory epithelium of the inner ear beyond that which has been achieved previously.

In some ernbodimermts, (a) and (b) can occur in any order or simultaneously.

[0011] In other aspects the disclosure provides method for producing an expanded population of cochlear or vestibular cells, by contacting the supporting cell with a first epigenetic agent that is (a) a lysine specific demethylase 1 (LSD1) inhibitor, an enhancer of zeste homolog 2 (EZH2) inhibitor, a disruptor of telomeric silencing 1-like (DOT1L) inhibitor, or a histone lysine demethylase (KDM) inhibitor and (b) a Wnt agonist. In some embodiments, (a) and (b) can occur in any order or simultaneously.

[0012] The cochlear supporting cell(s) or vestibular supporting cell(s) express(es) leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5). The cochlear supporting cell(s) or

vestibular supporting cell(s) are/is a mature cell(s). The expanded population of cochlear or vestibular cells expresses leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5).

[0013] The epigenetic agent in combination with the Wnt agonist increases the Lgr5 Activity of the expanded population of cochlear or vestibular cells by a factor of at least 10, 20, 30, 40, 50, 75, 100 or 200% compared to a Wnt agonist alone or a Wnt agonist in combination with valproic acid, wherein the Lgr5 Activity is measured in a Stem Cell Proliferation Assay

[0014] In further aspects the disclosure provides methods of treating a subject who has, or is at risk of, developing an inner ear hearing or balance disorder, by administering to the subject with a first epigenetic agent that is (a) a lysine specific demethylase 1 (LSD1) inhibitor, an enhancer of zeste homolog 2 (EZH2) inhibitor, a disrupter of telomeric silencing 1-like (DOT1L) inhibitor, or a histone lysine demethylase (KDM) inhibitor and (b) a Wnt agonist.

DETAILED DESCRIPTION

[0236] The invention is based upon the discovery that administering an epigenetic agent in combination with a Wnt agonist results in the proliferation of cochlear supporting cells or vestibular supporting cells while maintaining, in the daughter cells, the capacity to differentiate into cochlear hair cells or vestibular hair cells. Epigenetic modulationalone has no effect on the proliferation of cochlear supporting cells or vestibular supporting cells. Wnt agonists have previously been used to stimulate proliferation of supporting cells with some success. However, surprisingly, the combination of an epigenetic agent and Wnt agonist resulted in a surprising level of proliferation of cells in these contexts. Indeed, the combination of an epigenetic agent and a Wnt agonist increased proliferation of cochlear supporting cells or vestibular supporting cells relative to stimulation with either Wnt agonist or epigenetic inhibition alone. The combination of an epigenetic agent and a Wnt agonist therefore produces a larger population of expanded cochlear cells or vestibular cells compared to either Wnt agonist or epigenetic modulation alone. In other words, the combination of epigenetic modulation and a Wnt agonist is more effective at inducing self-renewal of cochlear supporting cells and vestibular supporting cells than either Wnt agonist or epigenetic modulation alone. Self-renewal of cochlear supporting cells or vestibular supporting cells, it is meant inducing the a cochlear supporting cell or vestibular supporting cell to proliferate while maintaining, in the daughter cells, the capacity to differentiate into cochlear hair cells, thus providing a therapy for treating a subject who has, or is at risk of, developing an inner ear hearing or balance disorder.

[0237] Cochlear cells have also been treated with Wnt agonists in combination with valproic acid (VPA) (McLean et al. 2017). The inventors have found that replacement of valproic acid with another epigenetic agent is advantageous because such epigenetic agents can be effective at lower concentrations than VPA, potentially simplifying delivery of the epigenetic agent to the inner ear, as well as minimizing the risk of side effects. Moreover, the combination of an alternative epigenetic agent and Wnt agonist can produce a greater population of expanded cells compared to the combination of a Wnt agonist and VPA.

[0238] The methods described herein can increase the proliferation of cochlear supporting cells or vestibular supporting cells. Typically, the cochlear supporting cell or vestibular supporting cell in which proliferation is stimulated expresses Lgr5 (Leucine-rich repeat-containing G-protein coupled receptor 5). However, the methods described herein may also stimulate proliferation of supporting cells with little or no Lgr5 expression.

[0241] The methods described can herein produce an expanded population of cochlea or vestibular cells. In some embodiments, the expanded cells are enriched for Lgr5 expression (i.e. a greater percentage of the expanded cell population express Lgr5 compared to the starting cell population).

[0242] Lgr5 is a member of GPCR class A receptor proteins that is expressed across a diverse range of tissues such as in the muscle, placenta, spinal cord and brain, and particularly as a biomarker of adult stem cells in certain tissues. Lgr5+ stem cells are the precursors for sensory hair cells that are present in cochlea and vestibular organs of the inner ear. Increasing the

population of Lgr5+ cochlear or vestibular cells is therefore beneficial because it increases the population of precursor cells which may differentiate into sensory hair cells.

[0243] The present invention provides compositions and methods for inducing the self-renewal of a cochlear supporting cells and vestibular supporting cells by by decreasing LSD1, EZH2, DOT1L, and/or KDM expression or activity in combination with a Wnt agonist.

[0244] Thus, in various aspects the invention provides compositions and methods for increasing proliferation of a cochlear supporting cell or vestibular supporting cell; producing an expanded population of cochlear or vestibular cells and treating an inner ear hearing or balance disorder in a subject by contacting a cochlear supporting cell or vestibular supporting cell, or administering to a subject, an LSD1 inhibitor EZH2, DOT1L, and/or KDM and a Wnt Agonist.

[0245] In another aspect of the invention, the cochlear supporting cell or vestibular supporting cell is further contacted with, or a subject is further administered with, a second epigenetic agent. In some embodiments, the second epigenetic agent is an HDAC inhibitor, for example valproic acid (VPA). The addition of a second epigenetic agent to the first epigenetic agent and Wnt agonist is advantageous because proliferation of the supporting cell population can be increased compared to the combination of either an epigenetic agent and Wnt agonist or Wnt agonist and valproic acid. In some embodiments, the expanded population of cells that can be produced following treatment with an epigenetic agent, a Wnt agonist and a second epigenetic agent is larger than the expanded population of cells that can be produced compared to the combination of either LSD1 inhibitor and Wnt agonist or Wnt agonist and valproic acid. The Lgr5+ cell population can be more enriched when a second epigenetic agent is used compared to the combination of a single epigenetic agent and a Wnt agonist, or the combination of a Wnt agonist and an HDAC inhibitor.

[0246] EPIGENETIC AGENTS

[0247] Epigenetic agents are agents that can modulate activity of epigenetic modifiers, mediators and modulators. Epigenetic modifiers are genes whose products modify the epigenome directly through DNA methylation, the post-translational modification of chromatin or the alteration of the structure of chromatin. Epigenetic mediators, are often the target of epigenetic modification, although they are rarely mutated themselves. The epigenetic mediators largely overlap with the genes involved in stem cell reprogramming and their role in cancer followed directly from the discovery of their reprogramming role. Epigenetic mediators are those genes whose products are the targets of the epigenetic modifiers. Epigenetic modulators are the genes lying upstream of the modifiers and mediators in signalling and metabolic pathways

[0248] In some embodiments, an agent having activity as an epigenetic agent is an HDAC inhibitor, an EZH2 inhibitor, an LSD1 inhibitor, a DOT1L inhibitor, or KDM inhibitor.

LSD1 INHIBITORS

[0249] LSD1 mediated H3K4 demethylation can result in a repressive chromatin environment that silences gene expression. LSD1 has been shown to play a role in development in various contexts. LSD1 can interact with pluripotency factors in human embryonic stem cells and is important for decommissioning enhancers in stem cell differentiation. Beyond embryonic settings, LSD1 is also critical for hematopoietic differentiation. LSD1 is overexpressed in multiple cancer types and recent studies suggest inhibition of LSD1 reactivates the all-trans retinoic acid receptor pathway in acute myeloid leukemia (AML). These studies implicate LSD1 as a key regulator of the epigenome that modulates gene expression through post-translational modification of histones and through its presence in transcriptional complexes.

[0250] Thus, a “LSD1 inhibitor” refers to an agent capable of the decreasing the expression or enzymatic activity of LSD1. For example a LSD1 inhibitor results in a decrease in H3K4 demethylation of a target gene in a cell, for instance, in a cochlear cell or a vestibular, cell

[0251] In certain embodiments, a LSD1 inhibitor decreases the expression or enzymatic activity of LSD1 by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity.

[0252] In certain embodiments, a LSD1 inhibitor decreases H3K4 demethylation by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity.

[0253] In some instances, a LSD1 inhibitor decreases H3K4 demethylation by at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more relative to a control, for example relative to a baseline level of activity.

[0254] In some instances, a LSD1 inhibitor modulates (i.e. increases or decreases) expression or activity of a target gene by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity,

[0255] In some instances, a LSD1 inhibitor modulates (i.e. increases or decreases) expression or enzymatic activity of LSD1 by at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more relative to a control, for example relative to a baseline level of activity.

[0256] In some instances a LSD1 inhibitor is reversible. In other instances the LSD1 inhibitor is irreversible.

EZH2 INHIBITORS

[0260] Enhancer of zeste homolog 2 (EZH2) is a histone-lysine N-methyltransferase enzyme encoded by EZH2 gene, that participates in histone methylation and, ultimately, transcriptional repression. EZH2 catalyzes the addition of methyl groups to histone H3 at lysine 27, by using the cofactor S-adenosyl-L-methionine. Methylation activity of EZH2 facilitates heterochromatin formation thereby silences gene function. Remodeling of chromosomal heterochromatin by EZH2 is also required during cell mitosis.

[0261] EZH2 is the functional enzymatic component of the Polycomb Repressive Complex 2 (PRC2), which is responsible for healthy embryonic development through the epigenetic maintenance of genes responsible for regulating development and differentiation EZH2 is

responsible for the methylation activity of PRC2, and the complex also contains proteins required for optimal function (EED, SUZ12, JARID2, AEBP2, RbAp46/48, and PCL).

[0283] About 30 JmjC domain-containing proteins have been identified as lysine demethylases in the human genome. Based on histone lysine sites and dem ethylation states, the JmjC domain- containing protein family is divided into six subfamilies: KDM2, KDM3, KDM4, KDM5, KDM6 and PHF. The JmjC domain-containing proteins belong to the Fe(II) and 2-oxoglutarate (2-OG)- dependent dioxygenases, which demethylate a variety of targets, including histones (H3K4, H3K9, H3K27, H3K36 as well as H1K26) and non-histone proteins. Unlike the LSD family, the JmjC- domain-containing histone demethylases (JHDMs) are able to erase all three kinds of histone lysine-methylation states since the JHDMs do not require protonated nitrogen for demethylation.

[0284] The KDM2 (also named FBXL) subfamily includes two members: KDM2A and KDM2B, KDM4 gene family, first identified in silico, consists of six members, including KDM4A, KDM4B, KDM4C, KDM4D, KDM4E and KDM4F. The KDM5 subfamily contains

four enzymes: KDM5A, KDM5B, KDM5C and KDM5D, which specifically remove methyl marks from H3K4me2/3. In the human genome, the KDM6 subfamily is comprised of KDM6A, KDM6B and UTY, which share a well-conserved JmjC histone catalytic domain.

[0285] KDM inhibitors are chemical compounds that inhibits lysine demethylases.

WNT AGONISTS

[0294] A Wnt agonist refers to an agent that increases the expression, levels, and/or activity of a Wnt gene, protein, or signaling pathway (e.g. TCF/LEF, Frizzled receptor family, Wifi, Left, Axin2, β-catemn) in a cell, for example, a cochlear cell. A Wnt agonist includes a GSK3 inhibitor, such as a GSK3-α or a GSK-3-β inhibitor. In some embodiments, the GSK3 inhibitor is a GSK3-b inhibitor.

[0295] The TCF/LEF family is a group of transcription factors that bind to DNA through a high mobility group domain, and which are involved in the Wnt signaling pathway where they recruit the coactivator β-catenm to enhancer elements of targeted genes. Frizzled is a family of G protein-coupled receptor proteins that serves as receptors in the Wnt signaling pathway. Frizzled receptors inhibit intracellular β-catemn degradation and activate TCF/LEF-mediated transcription.

[0296] In some embodiments, the Wnt agonist increases Wnt signaling in a cochlear or vestibular cell by about or at least about 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, or 500% or more (or at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more) or more relative to a control, for example relative to a baseline level of activity.

HDAC INHIBITORS

[0309] Histone deacetylases (HDAC) are a class of enzymes that remove acetyl groups (O=C-CH3) from an ε-N-acetyl lysine amino acid on a histone, allowing the histones to wrap the DNA more tightly. This is important because DNA is wrapped around histones, and DNA expression is regulated by acetylation and de-acetylation.

[0310] HDACs are classified in four classes depending on sequence homology to the yeast original enzymes and domain organization. The HDAC classes include HDACI, HDAC HA, HDAC IIB, HDAC III and HDAC IV.

[0311] Histone deacetylase (HDAC) inhibitors (HDACi, HDIs) are chemical compounds that inhibit histone deacetylases.

[0312] Thus, “HDAC inhibitor” refers to an agent capable of the decreasing the expression or enzymatic activity of HDAC. For example HDAC inhibitor results in a decrease in histone deacetylation of a target gene in a cell.

[0313] In certain embodiments, the HDAC inhibitor decreases the expression or enzymatic activity of HDAC by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity.

[0314] In certain embodiments, the HDAC inhibitor decreases histone deacetylation of a target gene by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity.

[0315] In some embodiments, the HDAC inhibitor increases expression or activity of a target gene by at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100% relative to a control, for example relative to a baseline level of activity.

[0316] In some embodiments, the HDAC inhibitor decreases expression or enzymatic activity of HDAC by at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more relative to a control, for example relative to a baseline level of activity.

MEASUREMENT OF SENSORINEURAL HEARING LOSS

[0322] Hearing loss can be assessed by several different tests. Such tests may determine the audibility of a sound to a patient and/or the intelligibility of the sound to a patient prior to or after treatment. The audibility of a sound is a measure of a patient’s ability to detect the sound (i.e. whether the patient can determine the presence or absence of a sound). The intelligibility of a sound is a measure of a patient’s ability to correctly identify the sound. For instance, hearing is assessed according to whether a patient can correctly identify a word or not. A patient with hearing loss may therefore neither be able to detect a sound nor correctly identify it (i.e. the sound is inaudible and unintelligible). However, audibility is not necessarily associated with intelligibility, and a patient may, for example, be able to detect a sound, but not correctly identify it (i.e. the sound is audible but unintelligible).

[0323] Pure tone audiometry

[0324] Assessment of a patient’s audibility function is typically carried out by an audiologist using an audiometer in a hearing test known as pure tone audiometry. Pure tone audiometry is a standard test used to assess the audibility of a sounds and is described in detail elsewhere (see, for example, Katz, I, Medwetsky, L, Burkard, R., & Hood, L. (2009) Handbook of Clinical Audiology. Philadelphia, Pennsylvania: Lippincott Williams and Wilkins). Pure tone audiometry is typically carried out in a sound-treated booth, which reduces ambient noise levels that may interfere with the detection of low-level sound stimuli.

[0325] In pure tone audiometry, a patient is exposed to pure tone stimuli at specific frequencies to determine the patient’s hearing threshold at each frequency. Standard audiometry measures a patient’s pure tone hearing threshold at each of the following frequencies 0.25kHz, 0.5kHz, 1kHz, 2kHz, 3kHz, 4kHz, 6kHz and 8kHz. However, a patient’s hearing threshold does not need to be determined at all of these frequencies to ascertain whether or not the patient has sensorineural hearing loss. For instance, a subset frequencies, or a single frequency is tested to identify a patient with sensorineural hearing loss.

[0326] To determine the hearing threshold, the volume of the pure tone is altered to determine the lowest level of stimuli that the patient is able to detect. The lowest level of stimuli (corresponding to the quietest sound) is the pure tone hearing threshold at a given frequency. The pure tone threshold is typically measured in a patient using according decibels in hearing level (dB HL) on an audiometer. However, hearing thresholds may also be determined using other methods known to the person skilled in the art. For example, hearing function is measured by Auditory Brainstem Response (ABR) testing or Auditory Steady State Response (ASSR) testing. Other tests can also be used to determine hearing function in a patient. For instance, Distortion product otoacoustic emissions (DPOAEs) can be used to measure outer hair cell function and loss and is used in differential diagnosis of hearing loss arising from hair cell loss from hearing loss associated with higher level processing (e.g. auditory neuropathy).

[0327] Pure tone thresholds are plotted on a graph to produce an audiogram for the patient.

[0328] Pure tone thresholds measured across different frequencies may also be averaged to provide a pure tone average. For instance, a patient that has pure tone hearing thresholds of 50 dB HL at 0.5Hz, 60 dB HL at 1kHz, 65 dB HL at 2kHz and 70 dB at 4kHz would have a pure tone average of 61.25 dB HL, when measured across 0.5kHz, 1kHz, 2kHz and 4kHz.

[0329] Pure tone averages are calculated across different frequencies. Pure tone thresholds at any subset of frequencies are used to calculate pure tone averages. In some embodiments, the average of the patient hearing threshold is measured across 0.5kHz, 1kHz, 2kHz and 4kHz. In some embodiments, pure tone average is measured across 4kHz, 6kHz and 8kHz. Measurement of pure tone average across 4kHz, 6kHz and 8kHz is useful when seeking to assess the patient’s hearing function at the higher frequencies within the standard audiometric frequencies.

[0330] Sensorineural hearing loss can be categorized according to its severity. The severity of hearing loss is determined by the hearing levels at which a threshold level is obtained in a patient by pure tone audiometry. Severity of hearing loss is classified according to hearing thresholds using the following definitions:

• Normal; 25 dB HL or less

• Mild: at least 25 dB HL and no more than 40 dB HL

• Moderate: at least 40 dB HL and no more than 55 dB HL

• Moderately Severe: at least 55 dB HL and no more than 70 dB HL

• Severe: at least 70 dB HL and no more than 90 dB HL

• Profound: at least 90 dB HL or more

These measures of severity are standard measures in the field (see Goodman, A. (1965).

Reference zero levels for pure tone audiometer. ASHA, 7, 262-263). In some embodiments, the severity of hearing loss is classified according to a patient’s hearing thershold at a single frequency (for example, 0.25kHz, 0.5kHz, 1kHz, 2kHz, 3kHz, 4kHz, 6kHz or 8kHz) . For instance, a patient may have mild hearing loss at 8kHz, and normal hearing at the other standard audiometric frequencies. In some embodiments, the severity of hearing loss is classified according to pure tone average, when measured across a subset of frequencies. In certain such embodiments, the severity of hearing loss is classified according to the pure tone average across 0.5kHz, 1kHz, 2kHz and 4kHz. For example, a patient may have moderate hearing loss according to their pure tone average across 0.5kHz, 1kHz, 2kHz and 4kHz, but have moderately severe hearing loss at a single frequency (e.g. 8kHz). In other embodiments, the severity of hearing loss is classified according to the pure tone average across 4kHz, 6kHz and 8kHz.

[0331] A patient that has hearing threshold of 25dB HL or less at standard audiometric frequencies (i.e. 0.25kHz, 0.5kHz, 1kHz, 2kHz, 3kHz, 4kHz, 6kHz and 8kHz) has normal hearing. The patient’s audiogram is also a normal audiogram.

Word Recognition tests

[0332] Alternatively, or in addition to pure tone audiometry, hearing loss is assessed using a word recognition test. A word recognition test measures the patient’s ability to correctly identify a word, thereby providing a measure of sound intelligibility (in particular, speech intelligibility) that may not be provided by pure tone audiometry. In some embodiments, a word recognition score is used to determine the patient’s ability to correctly identify words prior to treatment.

[0333] A standard word recognition in quiet test, also referred to herein as a standard word recognition test, is a test administered by an audiologist that measures a patient’s speech intelligibility in recognizing words in a quiet environment. A quiet environment is an environment with little to no background noise.

[0334] A standard word recognition test is used to determine a person’s ability to recognize words selected from a word list and presented to the patient at a given decibel (dB) level. In some embodiments, the standard word recognition test is used to determine a patient’s ability to recognize words at more than one decibel level.

[0335] In some embodiments, the standard word recognition test assesses the patient’s ability to identify 50 words. However, the number of words presented to the patient is more or less than 50. For example, in some embodiments, the standard word recognition test is for 25 words. In other embodiments, the standard word recognition test is for 10 words.

[0336] A standard word recognition test is used to generate a standard word recognition (%) score which is calculated using the formula:


[0337] In some embodiments, the standard word recognition score is expressed as the number of words that are correctly recognized in the test.

[0338] In some embodiments, a list of words is administered to each ear, and a standard word recognition score is calculated for each ear. Herein the results of the standard word recognition score refer to the ear that has been/will be treated.

[0339] A standard word recognition test is carried out using any list of words. However, standard word lists are typically used in a standard word recognition test. In some embodiments, each test word is embedded in a carrier phrase. Example of carrier phrases are: “Say the word again”, “You will say", or “Say the word".

[0340] In some embodiments, the standard word recognition test is the Maryland consonant-vowel nucleus-consonant (CNC) word test. The Maryland CNC word test has been described, for example, in Mendel, L.L., Mustain, W.D., & Magro, J. (2014). Normative data for the Maryland CNC Test. Journal of the American Academy of Audiology, 25, 775-781.

[0341] The Maryland CNC word test is a standard word recognition test that uses phonemically balanced word lists comprising words that are consonant-nucleus-consonant (CNC) monosyllables. These CNC lists are balanced so that each initial consonant, each vowel, and each final consonant appears with the same frequency within each list. The Maryland CNC test has 10 lists of 50 words.

[0342] In some embodiments, the Maryland CNC Test uses words from Lehiste and Peterson’s phonemically balanced word lists, all of which were CNC monosyllables, for example as described in Lehiste I, Peterson GE. (1959) Linguistic considerations in the study of speech intelligibility. Journal of the Acoustical Society of America 31(3): 280‒286.

[0343] In some embodiments, the Mary land CNC Test uses words from revised CNC lists that eliminate rare literary words and proper names, for example as described in Peterson GE, Lehiste I. (1962) Revised CNC lists for auditory tests. Journal of Speech and Hearing Disorders 27:62‒70.

[0344] In some embodiments, the Maryland CNC Test uses words from modified CNC word lists that take into consideration the effects of coarticulation, where the acoustic properties of phonemes are influenced by those phonemes that immediately precede and follow them, for example as described in Causey GD, Hood LJ, Hermanson CL, Bowling LS. (1984) The Maryland CNC Test: normative studies. Audiology 23(6): 552‒568. The words of the Maryland CNC test are spoken within the carrier phrase: ‘Say theagain,’

[0345] In some embodiments, the standard word recognition test is the C.I.D Auditory Test W-22 (CID W-22) test. The CID W-22 test has been described, for example, in Hirsh, I.J, Davis, H. Silverman, S.R., Reynolds, E.G. Eldert, E., & Benson, R.W. (1952). Development of Materials for Speech Audiometry. Journal of Speech, Language, and Hearing Research, 17(3), 321-337.

[0346] The CID W-22 test uses 200 monosyllabic words which are divided into four lists of 50 words each. Each list is phonetically balanced. The speech sounds within the list occur with the same relative frequency as they do in a representative sample of English speech. There are three criteria for the vocabulary in the phonetically balanced word lists. First, all the words must be one-syllable words with no repetition of words in the different lists. Second, any word chosen should be a familiar word. This second criterion is to minimize the effect of differences in the educational background of subjects. Third, the phonetic composition of each word list should correspond to that of English as a whole as closely as possible. The words of the CID W-22 test are spoken with the carrier phrase: "You will say".

[0347] In some embodiments the standard word recognition test is the NU No.6 test. The NU No.6 has been described, for example, in Tillman, T. W., & Carhart, R. (1966). An expanded test for speech discrimination utilizing CNC monosyllabic words: Northwestern University Auditory Test No. 6. Northwestern Umv Evanston Il Auditory Research Lab.

[0348] In some embodiments, the NU No.6 test uses 4 lists of 50 words, for example, as described in Table 28-2 of Tillman, T. W., & Carhart, R. (1966). The words of the NU No.6 test are spoken with the carrier phrase: “Say the word" .

[0349] In some embodiments the standard word recognition test is the Maryland CNC test, using the words list and carrier phrases as defined in Causey GD, Hood LJ, Hermanson CL, Bowling LS. (1984) The Maryland CNC Test: normative studies. Audiology 23(6): 552‒568. In certain such embodiments, the word signal is provided to the patient at 40 dB above speech perception level.

Words-in-Noise (WIN) Test

[0350] A “Words-in-Noise (WIN) Test” is a test administered by an audiologist to measure a patient’s speech intelligibility in recognizing words in the presence of background noise.

[0351] The WIN test consists of administering words to an ear at a varying signal-to-noise ratio (SNR) level. The signal-to-noise ratio is the ratio of the strength of the signal carrying information (e.g. the test word signal), relative to the signal of interference (e.g. noise), and is typically expressed in decibels. In some embodiments, the background noise is multi-talker babble at a fixed decibel level.

[0352] In some embodiments the multi-talker babble is comprised of six talkers (three female, three male) at a fixed level, for example, as described in Wilson, R.H., Abrams, H.B., & Pillion, A.L. (2003). A word-recognition task in multi-talker babble using a descending presentation mode from 24 dB to 0 dB signal to babble. Journal of Rehabilitation Research and Development, 40(4), 321-328.

[0353] In some embodiments, the background noise is maintained at a fixed decibel level, and the variation in the SNR decibel level is achieved by varying the decibel level of the test word signal. The SNR decibel level is therefore the SNR above the background noise. For example if the level of multi-talker babble is fixed at 70 dB SPL, and the level of the test word signal varied from 70 dB SPL to 94 dB SPL, this would give a SNR decibel level variation of 0 dB to 24 dB.

[0354] In some embodiments, the test words that are used are from any list described herein for the word recognition tests. In some embodiments, the word-in-noise test is for 70 words. In other embodiments, the words-in-noise test is for 35 words.

[0355] In some embodiments, the test consists of administering 35 or 70 monosyllabic words from the NU No.6 word lists. The test words are spoken with the carrier phrase: “Say the word" .

[0356] In some embodiments, the WIN test is administered in a descending-level SNR paradigm. In these embodiments, the test words at the high SNR decibel level are presented first, followed by test words at gradually lower SNR decibel levels, with words at the lowest SNR decibel level administered last. The high SNR decibel level is the easiest setting for the patient to identify the signal words. The low SNR decibel levels is the most difficult setting for the patient to identify the signal words. In other embodiments, the WIN test is administered in a randomized-level SNR paradigm. In these embodiments, the test words are presented at different SNR decibel levels in a randomized order.

[0357] In some embodiments the SNR decibel level of the test words varies from 24 dB SNR (easiest condition) to 0 dB SNR (most difficult condition) in 4 dB decrements, for a total of seven SNR levels (i.e. 24 dB SNR, 20 dB SNR, 16 dB SNR, 12 dB SNR, 8 dB SNR, 4 dB SNR and 0 dB SNR).

[0358] In some embodiments the WIN test consists of administering 70 monosyllabic words from the NU No.6 word lists, where the SNR decibel level of the test words varies from 24 dB SNR (easiest condition) to 0 dB SNR (most difficult condition) in 4 dB decrements, for a total of seven SNR levels (i.e. 24 dB SNR, 20 dB SNR, 16 dB SNR, 12 dB SNR, 8 dB SNR, 4 dB SNR and 0 dB SNR). In this embodiment, the level of multi-talker babble is fixed at 70 dB SPL, and the level of the test word signal varies from 70 dB SPL to 94 dB SPL.

[0359] The ‘words-in-noise’ test is used to generate a words-in-noise score.

[0360] In some embodiments the words-in-noise score is given as a percentage of the total correct words recognized by the patient in the test and calculated using the formula:


METHODS OF USE

[0361] In certain embodiments, the present disclosure relates to inducing, promoting, or enhancing the growth, proliferation or regeneration of inner ear tissue, particularly inner ear supporting cells and hair cells. Some embodiments relate to methods for controlled proliferation of stem cells comprising an initial phase of inducing sternness while inhibiting differentiation and a subsequent phase of differentiation of the stem cells into tissue cells.

[0362] When cochlear supporting cell or vestibular supporting cell populations are treated with an agent in accordance to the methods of the invention, whether the population is in vivo or in vitro, the treated supporting cells exhibit stem-like behavior in that the treated supporting cells have the capacity to proliferate and differentiate and, more specifically, differentiate into cochlear hair cells or vestibular hair cells. In some instances, an agent induces and maintains the supporting cells to produce daughter stem cells that can divide for many generations and maintain the ability to have a high proportion of the resulting cells differentiate into hair cells. In certain embodiments, the proliferating stem cells express stem cell marker(s) selected from one or more of Lgr5, Sox2, Opem1, Phex, lin28, Lgr6, cyclin D1, Msx1, Myb, Kit, Gdnf3, Zic3, Dppa3, Dppa4, Dppa5, Nanog, Esrrb, Rexl, Dnmt3a, Dnmt3b, Dnmt31, Utf1, Tel1, Oct4, Klf4, Pax6, Six2, Zic1, Zic2, Otx2, Bmi1, CDX2, STAT3, Smad1, Smad2, smad2/3, smad4, smad5, and smad7. In some embodiments, the proliferating stem cells express stem cell marker(s) selected from one or more of Lgr5, the

[0363] In some embodiments, the methods are used to maintain, or even transiently increase stemness (i.e. self-renewal) of a pre-existing supporting cell population prior to significant hair cell formation. In some embodiments, the pre-existing supporting cell population comprises inner pillar cells, outer pillar cells, inner phalangeal cells, Deiter cells, Hensen cells, Boettcher cells, and/or Claudius cells. Morphological analyses with immunostammg (including cell counts) and lineage tracing across a Representative Microscopy Samples are used to confirm expansion of one or more of these cell-types. In some embodiments, the pre-existing supporting cells comprise Lgr5+ cells. Morphological analyses with immunostaining (including cell counts) and qPCR and in situ RNA hybridization is used to confirm Lgr5 upregulation amongst the cell population.

[0364] Advantageously, methods described herein can achieve these goals without the use of genetic manipulation. Germ-line manipulation used in many academic studies is not a therapeutically desirable approach to treating hearing loss. In general, the therapy involves the administration of a small molecule, peptide, antibody, or other non-nucleic acid molecule or nucleic acid delivery vector unaccompanied by gene therapy. In certain embodiments, the therapy involves the administration of a small organic molecule. In some instances, hearing

protection or restoration is achieved through the use of a (non-genetic) therapeutic that is injected in the middle ear and diffuses into the cochlea.

[0365] The cochlea relies heavily on all present cell types, and the organization of these cells is important to their function. For instance, supporting cells play an important role in neurotransmitter cycling and cochlear mechanics. Thus, maintaining a rosette patterning within the organ of Corti is important for maintaining function. Cochlear mechanics of the basilar membrane activate hair cell transduction. Due to the high sensitivity of cochlear mechanics, it is also desirable to avoid masses of cells. In all, maintaining proper distribution and relation of hair cells and supporting cells along the basilar membrane, even after proliferation, is likely a desired feature for hearing as supporting cell function and proper mechanics is necessary for normal hearing.

[0366] In some embodiments, the cell density of hair cells in a cochlear cell population is expanded in a manner that maintains, or even establishes, the rosette pattern characteristic of cochlear epithelia.

[0367] In certain embodiments, the cell density of hair cells is increased in a population of cochlear cells comprising both hair cells and supporting cells. The cochlear cell population can be an in vivo population (i.e. comprised by the cochlear epithelium of a subject) or the cochlear cell population is an in vitro (ex vivo) population. If the population is an in vitro population, the increase in cell density is determined by reference to a Representative Microscopy Sample of the population taken prior and subsequent to any treatment. If the population is an in vivo population, the increase in cell density is determined indirectly by determining an effect upon the hearing of the subject with an increase in hair cell density correlating to an improvement in hearing,

[0368] In some embodiments, supporting cells placed in a Stem Cell Proliferation Assay in the absence of neuronal cells form ribbon synapses.

[0369] In a native cochlea, patterning of hair cells and supporting cells occurs in a manner parallel to the basilar membrane. In some embodiments, the proliferation of supporting cells in a cochlear cell population is expanded in a manner that the basilar membrane characteristic of cochlear epithelia.

[0370] In some embodiments, the number of supporting cells in an initial cochlear cell population is selectively expanded by treating the initial cochlear cell population with a composition of the present disclosure to form an intermediate cochlear cell population, wherein the ratio of supporting cells to hair cells in the intermediate cochlear cell population exceeds the ratio of supporting cells to hair cells in the initial cochlear cell population. The expanded cochlear cell population is, for example, an in vivo population, an in vitro population or even an in vitro explant. In some embodiments, the ratio of supporting cells to hair cells in the intermediate cochlear cell population exceeds the ratio of supporting cells to hair cells in the initial cochlear cell population. For example, in some embodiments, the ratio of supporting cells to hair cells in the intermediate cochlear cell population exceeds the ratio of supporting cells to hair cells in the initial cochlear cell population by a factor of 1.1, 1.5, 2, 3, 4, 5 or more. In some instances, the capacity of a composition to expand a cochlear cell population is be determined by means of a Stem Cell Proliferation Assay.

[0371] In some embodiments, the number of stem cells in a cochlear cell population is expanded to form an intermediate cochlear cell population by treating a cochlear cell population with a composition of the present disclosure wherein the cell density of stem cells in the intermediate cochlear cell population exceeds the cell density of stem cells in the initial cochlear cell population. The treated cochlear cell population is, for example, an in vivo population, an in vitro population or even an in vitro explant. In one such embodiment, the cell density of stem cells in the treated cochlear cell population exceeds the cell density of stem cells in the initial cochlear cell population by a factor of at least 1.1, 1.25, 1.5, 2, 3, 4, 5 or more. In vitro cochlear cell populations may expand significantly more than in vivo populations; for example, in certain embodiments the cell density of stem cells in an expanded in vitro population of stem cells is at least 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 75, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000 or even 3000 times greater than the cell density of the stem cells in the initial cochlear cell population. In some instances, the capacity of a composition to expand a cochlear cell population is determined by means of a Stem Cell Proliferation Assay.

[0372] In some embodiments, a cochlear supporting cell population or a vestibular supporting cell population is treated with a composition of the present disclosure to increase the Lgr5 activity of the population. For example, in some instances an epigenetic agent and a Wnt agonist has the capacity to increase and maintain the Lgr5 activity of an in vitro population of

cochlear supporting cells or vestibular supporting cells by factor of at least 1.2, 1.5, 2, 3, 4, 5, or more, in some embodiments, the epigenetic agent and a Wnt agonist has the capacity to increase the Lgr5 activity of an in vitro population of cochlear supporting cells or vestibular supporting cells by factor of 2, 3, 5 10, 100, 500, 1000, 2000 or even 3000. Increases in Lgr5 activity may also be observed for in vivo populations but the observed increase is less than in vitro populations. In some instances, the epigenetic agent and a Wnt agonist inhibitor has the capacity to increase the Lgr5 activity of an in vivo population of cochlear supporting cells or vestibular supporting cells by about or at least about 5%, 10%, 20%, 30% or more. In some instances, the capacity of the epigenetic agent and a Wnt agonist for such an increase in Lgr5 activity is demonstrated, for example, in an In Vitro Lgr5+ Activity Assay, and in an in vivo population is demonstrated, for example, in an In Vivo Lgr5+ Activity Assay, as measured by isolating the organ and performing morphological analyses using immunostaining, endogenous fluorescent protein expression of Lgr5, and qPCR for Lgr5.

[0373] In some embodiments, the epigenetic agent in combination with a Wnt agonist has the capacity to increase the Lgr5 Activity of an in vitro population of cochlear supporting cells or vestibular supporting cells by a factor of 10, 20, 30, 40, 50, 75, 100 or 200% compared to a Wnt agonist alone as measured for example in an In Vitro Lgr5+ Activity Assay.

[0374] In some embodiments, the epigenetic agent in combination with CHIR99021has the capacity to increase the Lgr5 Activity of an in vitro population of cochlear supporting cells or vestibular supporting cells by a factor of 10, 20, 30, 40, 50, 75, 100 or 200% compared to CHIR99021in combination with VTA, as measured for example in an In Vitro Lgr5+ Activity Assay.

[0375] In some embodiments, the epigenetic agent in combination with a Wnt agonist has the capacity to increase the Lgr5 proliferation of an in vitro population of cochlear supporting cells or vestibular supporting cells by factor of 10, 20, 30, 40, 50, 75, 100 or 200% compared to a Wnt agonist alone as measured for example in a in a in a Stem Cell Proliferation Assay.

[0376] In some embodiments, the epigenetic agent in combination with a Wnt agonist has the capacity to increase the Lgr5 proliferation of an in vitro population of cochlear supporting cells or vestibular supporting cells by factor of 10, 20, 30, 40, 50, 75, 100 or 200% compared to a Wnt agonist in combination with a VPA as measured for example in a in a in a Stem Cell Proliferation Assay.

[0377] In some embodiments, the epigenetic agent in combination with a Wnt agonist and VPA has the capacity to increase the Lgr5 proliferation of an in vitro population of cochlear supporting cells or vestibular supporting cells by factor of 10, 20, 30, 40, 50, 75, 100 or 200% compared to a in combination with a VPA as measured for example in a in a in a Stem Cell Proliferation Assay.

[0378] In addition to increasing the Lgr5 activity of the population, the number of Lgr5+ supporting cells in a cochlear or vestibular cell population is increased by treating a cochlear or vestibular cell population containing Lgr5+ supporting cells (whether in vivo or in vitro) with a composition of the present disclosure. In general, the cell density of the stem/progenitor supporting cells may expand relative to the initial cell population via one or more of several mechanisms. For example, in some embodiments, newly generated Lgr5+ supporting cells is generated that have increased stem cell propensity (i.e. greater capacity to differentiate into hair cell). By way of further example, in some embodiments no daughter Lgr5+ cells are generated by cell division, but pre-existing Lgr5+ supporting cells are induced to differentiate into hair cells. By way of further example, in some embodiments no daughter cells are generated by cell division, but Lgr5- supporting cells are activated to a greater level of Lgr5 activity and the activated supporting cells are then able to differentiate into hair cells. Regardless of the mechanism, in some embodiment a composition of the present disclosure (e.g. a composition comprising an epigenetic agent and a Wnt agonist and optionally a second epigenetic agent) has the capacity to increase the cell density of Lgr5+ supporting cells in an in vitro isolated cell population of cochlear supporting cells or vestibular supporting cells by factor of at least 5, 10, 50, 100, 500, 1000, or 2000. Increases in the cell density of Lgr5+ supporting cells may also be observed for in vivo populations but the observed increase is somewhat more modest. For example, in some embodiments the composition has the capacity to increase the cell density of Lgr5+ supporting cells in an in vivo population of cochlear supporting cells or vestibular supporting cells by about or at least about 5%, 10%, 20%, 30% or more. The capacity of the composition (for such an increase in Lgr5+ supporting cells in an in vitro population is demonstrated, for example, in a Stem Cell Proliferation Assay or in an appropriate in vivo assay. In some embodiments, a composition of the present disclosure has the capacity to increase the

number of Lgr5+ cells in the cochlea by inducing expression of Lgr5 in cells with absent or low detection levels of the protein, while maintaining Native Morphology. In some embodiments, a composition has the capacity to increase the number of Lgr5+ cells in the cochlea or vestibular organ by inducing expression of Lgr5 in cells with absent or low detection levels of the protein, while maintaining Native Morphology and without producing Cell Aggregates.

[0379] Included in the invention are methods of increasing proliferation of a Lgr5+ cochlear supporting cell by contacting a cochlear supporting cell with an epigenetic agent and a Wnt agonist. Optionally, the cell is further contacted with an epigenetic agent such as an HDAC inhibitor. In some embodiments, the HDAC inhibitor is VTA.

[0380] Included in the invention are methods of increasing proliferation of a vestibular supporting cell by contacting a vestibular supporting cell with an epigenetic agent and a Wnt agonist. Optionally, the cell is further contacted with an epigenetic agent such as an HDAC inhibitor. In some embodiments, the HDAC inhibitor is VPA.

[0381] In the various methods Lgr5+ cochlear cell or vestibular cell proliferation is increased compared to a vehicle control.

[0382] In some embodiments, the epigenetic agent and the Wnt agonist increases Lgr5+ cochlear supporting cell or vestibular supporting cell proliferation by at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500% or more (or at least about 1.1,

1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more), relative to a vehicle control.

[0383] In some embodiments, the epigenetic agent and the Wnt agonist in combination with a second epigenetic agent increases Lgr5+ cochlear supporting cell or vestibular supporting cell proliferation by at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500% more (or at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more) relative to a Wnt agonist alone in a Stem Cell Proliferation Assay.

[0384] In some embodiments, the epigenetic agent and the Wnt agonist in combination with a second epigenetic agent increases Lgr5+ cochlear supporting cell or vestibular supporting cell proliferation by at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500% more (or at least about 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more) relative to Wnt agonist in combination with VPA in a Stem Cell Proliferation Assay.

[0385] In some embodiments, the epigenetic agent and the Wnt agonist increases Lgr5+ cochlear supporting cell or vestibular supporting cell proliferation by at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500% or more (or at least about 1.1, 1 2 1.3, 1.4, 1.5, 1.6, 1 7 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 500, 1000-fold or more), relative to a Wnt agonist alone, as measured in a Stem Cell Proliferation Assay.

[0386] In some embodiments, the epigenetic agent and the Wnt agonist increases Lgr5+ cochiear supporting cell or vestibular supporting cell proliferation by at least 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500% or more (or at least about 1 1

1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100,

200, 500, 1000-fold or more), relative to a Wnt agonist in combination with VPA, as measured in a Stem Cell Proliferation Assay.

[0387] Also included are methods for expanding a population of cochlear cells in a cochlear tissue comprising a parent population of cells by contacting the cochlear tissue with an epigenetic agent and a Wnt agonist to form an expanded population of cells in the cochlear tissue.

[0391] In some embodiments, the cochlear cell is in a cochlear tissue. In some embodiments, the cochlear tissue is in a subject

[0392] Some embodiments relate to methods of treating a subject who has, or is at risk for developing, hearing loss or reduced auditory function. The prophylaxis and/or treatment of acute and chronic ear disease and hearing loss, dizziness and balance problems especially of sudden hearing loss, acoustic trauma, hearing loss due to chronic noise exposure, presbycusis, trauma during implantation of the inner ear prosthesis (insertion trauma), dizziness due to diseases of the inner ear area, dizziness related and/or as a symptom of Meniere’s disease, vertigo related and/or as a symptom of Meniere’s disease, tinnitus, hyperacusis and hearing loss due to antibiotics and cytostatics and other drugs.

[0393] Some embodiments include methods to prevent, reduce, or treat the incidence and/or severity of inner ear disorders and hearing impairments involving inner ear tissue, particularly inner ear hair cells, their progenitors, and optionally, the stria vascularis, and associated auditory nerves. Of particular interest are those conditions that lead to permanent hearing loss where reduced number of hair cells are responsible and/or decreased hair cell function. Also of interest are those arising as an unwanted side-effect of ototoxic therapeutic drugs including cisplatin and its analogs, aminoglycoside antibiotics, salicylate and its analogs, or loop diuretics.

[0394] Hearing loss or reduced auditory function is treated or prevented in a subject by contacting a Lgr5+ cochlear cell or administering to the subject an epigenetic agent and Wnt agonist to form an expanded population of cells in the cochlear tissue. Optionally, the cell is further contacted with a second epigenetic agent such as an HDAC inhibitor. In some embodiments, the HDAC inhibitor is VPA.

[0395] In various embodiments the epigenetic agent and Wnt agonist and optionally, the one or more additional epigenetic agents are administered to the subject systemically or locally. Systemic administration includes, but is not limited, to oral or parenteral administration. Parenteral routes include for example intramuscular (IM), subcutaneous (SC) and intravenous (IV). Local administration includes for example, mtratympanie or mtracochlear administration. More specific methods of local delivery are described herein. In some embodiments, both the epigenetic agent and Wnt agonist are administered locally. In other embodiments, both the epigenetic agent and Wnt agonist are administered systemically. In some embodiments the epigenetic agent is administered locally and the Wnt agonist is administered systemically. In other embodiments the epigenetic agent is administered systemically and the Wnt agonist is administered locally.

[0396] In some embodiments, the epigenetic agent and Wnt agonist are administered at the same time. In other embodiments, the epigenetic agent and Wnt agonist are administered at different times. In some embodiments the epigenetic agent is administered a period of time before the Wnt agonist. In other embodiments, the epigenetic agent is administered at a period of time after the Wnt agonist. For example, the epigenetic agent is administered 1, 2, 3, 4,5, 6, 7, 8,

9, 10, 12, 13, 14, 14, 15, 17, 18, 19, 20, 21. 22, 23, 24 hours or 1, 2, 3, 4, 5, 6, 7 or more days before the Wnt agonist. Alternatively, the epigenetic agent is administered 1, 2, 3, 4,5, 6, 7, 8, 9,

[0397] Hearing loss or reduced auditory function is treated or prevented utilizing the various methods described herein to increase Lgr5+ cochlear cell proliferation. The cochlear cell is contacted with an epigenetic agent and Wnt agonist at a “cell effective concentration” to form an expanded population of cells in the cochlear tissue. Optionally, the cell is further contacted with a second epigenetic agent such as an HDAC inhibitor. In some embodiments, the HDAC inhibitor is VPA.

In some embodiments, sufficient compound is delivered to achieve the “cell effective concentration” throughout the speech region of the human cochlea. In order to achieve this target concentration, a higher concentration of drug is instilled in the cochlea and diffuse throughout the speech region. In other embodiments, the Lgr5+ cochlear cell is contacted with the compound(s) at 2, 3,

4, 5, 10, 20, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000-fold more than the “cell effective concentration”, in situ ( i.e , within the cochlea).

[0400] Alternatively, hearing loss or reduced auditory function is treated by administering the compound(s) at the “formulation effective concentration”. A “formulation effective concentration” is a higher concentration than the “cell effective formulation”. For example, the “formulation effective concentration” is at least about 100 to 5000 fold higher than the “cell effective concentration”, or about 20 100, 250, 500, 750, 1000, 1250, 1500, 1750, 2000 fold higher than the “cell effective concentration”, or about 100, 200, 300, 400, 500, 600, 700, 800, 900 or100O fold higher than the “cell effective concentration”. Typically, the “formulation effective concentration” is at least about 1000 fold higher than the “cell effective concentration”.

[1329] It is understood that the gelling condition (e.g. gelling temperature) of the pharmaceutical composition or reconstituted solution of the present disclosure is measured with a variety of techniques in the art. In some embodiment, the gelling temperature is determined using a commercially available rheomoeter having a parallel plate geometry (e.g. with plate distance ranging from 0.5 mm to 1.0 mm). In some embodiments, the analysis is performed over a continuous temperature range (e.g. 15 °C to 40 °C) at a constant rate (e.g. 2 to 3 °C/min) and a deformation frequency of 0.74 Hz to 1 Hz. The geleation temperature is determined at the temperature whereby the shear storage modulus (G’) and the shear loss modulus (G”) are equal.

[1330] In some embodiments, the gelling agent comprises acacia, alginic acid, bentonite, poly(aerylic acid) (Carbomer), carboxymethyl cellulose, ethylcellulose, gelatin, hydroxyethyl cellulose, hydroxypropyl cellulose, magnesium aluminum silicate (Veegum), methylcellulose, poloxamer, hyaluronic acid sodium, polylacticglycolic acid sodium, chitosan, polyvinyl alcohol, sodium alginate, tragacanth, xanthan gum, or any combination thereof.

[1333] In some embodiments, the thermoreversible gelling agent comprises a poloxamer.

[1334] It is undersood that the gelling agent (e.g. the thermoreversible gelling agent) may also be a bulking agent of the pharmaceutical composition or reconstituted solution of the present disclosure. In some embodiments, a poloxamer (e.g. poloxamer 407) is the gelling agent and/or the bulking agent of the pharmaceutical composition or reconstituted solution of the present disclosure. Poloxomers are a general class of commercially available and pharmaceutically acceptable triblock copolymers of polyethylene oxide-polypropylene oxide-polyethylene oxide which exhibit relatively low viscosity at low temperatures (e.g. room termpature or below) but much high viscosities at elevated temperatures (e.g. body temperatures of approximately 37°C) whereby compositions containing such thermoreversible gelling agents effectively solidify in place. Other thermoreversible gelling agents such as polyethylene oxide ‒ polylactic acid-polyethylene oxide polymers are also suitable in various embodiments of the ptesent invention.

[1335] In some embodiments, the poloxamer (e.g. poloxamer 407) is the gelling agent and the bulking agent of the pharmaceutical composition or reconstituted solution of the present disclosure. In some embodiments, the presence of the poloxamer (e.g. poloxamer 407) in the pharmaceutical composition (e.g. the lyophilized pharmaceutical composition) alleviates the need for any other excipient (e.g. additional bulking agent). Such alleviation may provide one or more advantages to the pharmaceutical composition (e.g. enhanced stability and/or reduced reconstitution time).

[1336] In some embodiments, the poloxamer is selected from the group consisting of

[1365] Compounds or compositions described herein can be formulated in any manner suitable for a desired delivery route, e.g. transtympamc injection, transtympanic wicks and catheters, cochlear implants, and injectable depots. In some instances, compositions or formulations include one or more physiologically-acceptable components, including derivatives or prodrugs, solvates, stereoisomers, racemates, or tautomers thereof with any physiologically acceptable earners, diluents, and/or excipients.

[1366] As noted above, certain compositions are adapted for, and certain methods employ, administration to the middle ear or inner ear, for example, by local administration to the round window membrane. The membrane of the round windo w is the biological barrier to the inner ear space and represents the major obstacle for the local treatment of hearing impairment. The administered drug must overcome this membrane to reach the inner ear space. The drug can operatively (e.g. injection through the tympanic membrane) be placed locally to the round window membrane and can then penetrate through the round window membrane. Substances that penetrate the round window typically distribute in the perilymph and thus reach the hair cells and supporting cells.

[1367] The pharmaceutical compositions or formulations may also contain a membrane penetration enhancer, which supports the passage of the agents mentioned herein through the round window membrane. Accordingly, liquid, gel or foam formulations is used. It is also possible to apply the active ingredient orally or to employ a combination of delivery approaches.

[1368] Certain compositions are adapted for, and certain methods employ, administration to the middle ear or inner ear, for example, by intratympamc or transtympanic administration. Intratympanic (IT) delivery of drugs to the ear is increasingly used for both clinical and research purposes. Some groups have applied drugs in a sustained manner using microcatheters and microwicks, while the majority have applied them as single or as repeated IT injections (up to 8 injections over periods of up to 2 weeks).

[1369] Intratympanically applied drugs are thought to enter the fluids of the inner ear primarily by crossing the round window (RW) membrane. Calculations show that a major factor controlling both the amount of drug entering the ear and the distribution of drug along the length of the ear is the duration the drug remains in the middle ear space. Single, ‘one-shot’ applications or applications of aqueous solutions for few hours’ duration result in steep drug gradients for the applied substance along the length of the cochlea and rapidly declining concentration in the basal turn of the cochlea as the drug subsequently becomes distributed throughout the ear.

[1370] Other injection approaches include by osmotic pump, or, by combination with implanted biomaterial, by injection or infusion. Biomaterials that can aid in controlling release kinetics and distribution of drug include hydrogel materials, degradable materials. One class of materials that is used includes in situ gelling materials.

[1371] Delivery may also be enhanced via alternate means including but not limited to agents added to the delivered composition such as penetration enhancers, or could be through devices via ultrasound, electroporation, or high-speed jet.

[1372] Methods described herein can also be used for inner ear cell types that are produced using a variety of methods know to those skilled in the art including those cell types described in PCX Application No. W02012103012 A1.

[1373] With regard to human and veterinary treatment, the amount of a particular agent(s) that is administered is dependent on a variety of factors, including the disorder being treated and the severity of the disorder; activity of the specific agent(s) employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific agent(s) employed; the duration of the treatment; drugs used in combination or coincidental with the specific agent(s) employed; the judgment of the prescribing physician or veterinarian; and like factors known in the medical and veterinary arts.

[1374] The agents described herein are administered in a therapeutically effective amount to a subject in need of treatment. Administration of compositions described herein can be via any of suitable route of administration, for example, by intratympanie administration. Other routes include ingestion, or alternatively parenterally, for example intravenously, intra-arterially,

intraperitoneally, intrathecal fy, intraventricularly, iiitraurethralfy, intrasternally, intracramally, intramuscularly, mtranasally, subcutaneously, sublingually, transdermally, or by inhalation or insufflations, or topical by ear instillation for absorption through the skin of the ear canal and membranes of the eardrum. Such administration is as a single or multiple oral dose, defined number of ear drops, or a bolus injection, multiple injections, or as a short- or long-duration infusion. Implantable devices (e.g. implantable infusion pumps) may also be emplo d for the periodic parenteral delivery over time of equivalent or varyyling dosages of the particular formulation. For such parenteral administration, the compounds are formulated as a sterile solution in water or another suitable solvent or mixture of solvents. The solution may contain other substances such as salts, sugars (particularly glucose or mannitol), to make the solution isotonic with blood, buffering agents such as acetic, citric, and/or phosphoric acids and their sodium salts, and preservatives.

[1375] Compositions described herein can be administered by several methods sufficient to deliver the composition to the inner ear. Delivering a composition to the inner ear includes administering the composition to the middle ear, such that the composition may diffuse across the round window to the inner ear. It also includes administering a composition to the inner ear by direct injection through the round window membrane. Such methods include, but are not limited to auricular administration, by transtympanic wicks or catheters, or parenteral administration, for example, by intraauncular, transtympanic, or mtracochlear injection,

[1376] In particular embodiments, the compounds, compositions and formulations of the disclosure are locally administered, meaning that they are not administered systemically.

[1377] In one embodiment, a syringe and needle apparatus is used to administer compounds or compositions to a subject using auricular administration. A suitably sized needle is used to pierce the tympanic membrane and a wick or catheter comprising the composition is inserted through the pierced tympanic membrane and into the middle ear of the subject. The device is inserted such that it is in contact with the round window or immediately adjacent to the round window. Exemplary devices used for auricular administration include, but are not limited to, transtympanic wicks, transtympanic catheters, round window microcatheters (small catheters that deliver medicine to the round window), and Silverstein Microwicks™ (small tube with a “wick” through the tube to the round window, allowing regulation by subject or medical professional).

[1378] In some embodiments, a syringe and needle apparatus is used to administer compounds or compositions to a subject using transtympamc injection, injection behind the tympanic membrane into the middle and/or inner ear. The formulation is administered directly onto the round window membrane via transtympanic injection or is administered directly to the cochlea via intra cochlear injection or directly to the vestibular organs via intravestibuiar injection.

[1379] In some embodiments, the delivery device is an apparatus designed for administration of compounds or compositions to the middle and/or inner ear. By way of example only: GYRUS Medical GmbH offers micro-otoscopes for visualization of and drug delivery to the round window niche; Arenberg has described a medical treatment device to deliver fluids to inner ear structures in U.S. Pat. Nos. 5,421,818; 5,474,529; and 5,476,446, each of which is incorporated by reference herein for such disclosure. U.S. patent application Ser. No. 08/874,208, which is incorporated herein by reference for such disclosure, describes a surgical method for implanting a fluid transfer conduit to deliver compositions to the inner ear. U.S. Patent Application Publication 2007/0167918, which is incorporated herein by reference for such disclosure, further describes a combined otic aspirator and medication dispenser for transtympanic fluid sampling and medicament application.

[1380] In some embodiments, a compound or composition disclosed herein is administered to a subject in need thereof once. In some embodiments, a compound or composition disclosed herein is administered to a subject in need thereof more than once. In some embodiments, a first administration of a compound or composition disclosed herein is followed by a second, third, fourth, or fifth administration of a compound or composition disclosed herein.

[1381] The number of times a compound or composition is administered to an subject in need thereof depends on the discretion of a medical professional, the disorder, the severity of the disorder, and the subject’s response to the formulation. In some embodiments, the compound or composition disclosed herein is administered once to a subject in need thereof with a mild acute condition. In some embodiments, a compound or composition disclosed herein is administered more than once to a subject in need thereof with a moderate or severe acute condition. In the case wherem the subject’s condition does not improve, upon the doctor’s discretion the compound or composition is administered chronically, that is, for an extended period of time, including

[1422] “Lineage Tracing” as used herein is using a mouse line that enables fate tracing of any cell that expresses a target gene at the time of reporter induction. This can include hair cell or supporting cells genes (Sox2, Lgr5, Myosin VIIa, Pou4f3, etc.). For example, lineage tracing may use an Lgr5-EGFP-IRES-creERT2 mouse crossed with a reporter mouse, which upon induction, allows one to trace the fate of cells that expressed Lgr5 at the time of induction. By further example, Lgr5 cells can be isolated into single cells and cultured in a Stem Cell Proliferation Assay to generate colonies, then subsequently differentiated in a Differentiation Assay and analyzed for cell fate by staining for hair cell and/or supporting cell proteins and determining the reporter co-localization with either hair cell or supporting cell staining to determine the Lgr5 cells’ fate. In addition, lineage tracing can be performed in cochlear explants to track supporting cell or hair cell fate within the intact organ after treatment. For example, Lgr5 cell fate can be determined by isolating the cochlea from a Lgr5-EGFP-IRES-creERT2 mouse crossed with a reporter mouse and inducing the reporter in Lgr5 cells before or during treatment. The organ can then be analyzed for cell fate by staining for hair cell and/or supporting cell proteins and determining the reporter co-localization with either hair cell or supporting cell staining to determine the Lgr5 cells’ fate. In addition, lineage tracing can be performed in vivo track supporting cell or hair cell fate within the intact organ after treatment. For example, Lgr5 cell fate can be determined inducing a reporter in an Lgr5-EGFP-IRES-creERT2 mouse crossed with a reporter mouse, treating the animal, then isolating the cochlea. The organ can then be analyzed for cell fate by staining for hair cell and/or supporting cell proteins and determining the reporter co-localization with either hair cell or supporting cell staining to determine the Lgr5 cells’ fate. Lineage tracing is performed using alternative reporters of interest as is standard in the art.
