Definitions
- the present invention relates to therapeutic uses of compounds for treating, inhibiting, and/or preventing loss of hearing.
- NIHL Antibiotic-induced hearing impairment
- Neonates admitted to the neonatal intensive care unit have ten times the rate of hearing loss as neonates not admitted, often associated with the administration of antibiotics.
- the spiral-shaped cochlea of the inner ear is responsible for detecting sound.
- Inner hair cells lining the cochlea transform the mechanical vibrations of sound waves into chemical signals. These chemicals are then released from the hair cells and received by receptors on the auditory nerve fibers that send electrical impulses to the brain.
- the inner ear cells lining the cochlea can be destroyed by the use of antibiotics, leading to a condition called sensorineural hearing impairment.
- hearing aid which functions to amplify sound.
- Hearing aids are non-invasive and can improve an individual's ability to hear.

Description
- This application claims the benefit of U.S. provisional patent application Ser. No. 63/050,568 filed Jul. 10, 2020, under 35 USC § 119(e) and 35 U.S.C. § 111(a) (hereby specifically incorporated herein by reference).
- NIH/NIDCD 1R43DC019065, NIH/NIDCD R01DC015444, Office of Naval Research (ONR) N00014-18-1-2507, Department of Defense (DoD)/USAMRMC-RH170030.
- The present invention relates to therapeutic uses of compounds for treating, inhibiting, and/or preventing loss of hearing.
- Over 35 million Americans suffer from hearing impairment. In mammals, hair cell impairment is permanent. Antibiotic-induced hearing impairment (NIHL) is a permanent side effect from often necessary medical care. Neonates admitted to the neonatal intensive care unit have ten times the rate of hearing loss as neonates not admitted, often associated with the administration of antibiotics. The spiral-shaped cochlea of the inner ear is responsible for detecting sound. Inner hair cells lining the cochlea transform the mechanical vibrations of sound waves into chemical signals. These chemicals are then released from the hair cells and received by receptors on the auditory nerve fibers that send electrical impulses to the brain. The inner ear cells lining the cochlea can be destroyed by the use of antibiotics, leading to a condition called sensorineural hearing impairment.
- Currently, there are no clinically proven medications for the treatment of hearing impairment (sensorineural and neural), or tinnitus associated with the inner ear, and a medication that could be used to prevent, alleviate, or eliminate hearing impairment (or tinnitus) would thus be very desirable. The most common remedy for individuals suffering from severe sensorineural hearing impairment is a hearing aid, which functions to amplify sound. Hearing aids are non-invasive and can improve an individual's ability to hear. However, hearing aids can often be quite conspicuous and embarrassing to the wearer and hearing aids do not return hearing to normal levels. Furthermore, hearing aids amplify sound indiscriminately, sometimes amplifying sounds that an individual does not wish to hear, such as environmental noise.

FIG. 2A-B , Momelotinib protects from aminoglycoside toxicity in cochlear explants of P3 FVB mice. FVB mice were bred in the Creighton University animal facility. Procedures were approved by the IACUC committee of the Creighton University. 2A) Inner ears were collected from the post-natal day 3 (P3) FVB mice and transferred onto a filter (Millicell, PICM03050; Millipore) soaked in culturing medium. The filter was placed in 6-well culture plates with 1.2 mL medium outside the filter. The culturing medium is DMEM (10565-018; gibco) with 1% FBS (16000-044; gibco), 500 μL ampicillin (A5354; Sigma), 100 μL N-2 supplement (17502-048, gibco) and 100 μL B-27 supplement (17504-044, gibco). After culturing for 24 h at 37° C. in 5% CO2, 1 mL culturing medium with MMB at 0.2 μM, 200 μM MMB alone or without MMB and added both inside and outside the filter to preincubate for another 1 h before adding gentamicin solution. A 50 μg/mL gentamicin (G1397, Sigma) was chosen to induce around 35% hair cell death after incubation for 24 h at 37° C. For compound CYT-387 or MMB (A10263, AdooQ). The procedures were performed under sterile condition in the culture hood. Cochleae were then fixed with 4% PFA for 30 min and stained with Alexa Fluor 555 phalloidin in to determine the survival rate of the hair cells. All the cochleae images were taken with Zeiss 700 confocal microscopy. Immunofluorescent images of cochlea stained with phalloidin (red) at the middle turn region shows minimal levels of hair cell loss when cotreated with MMB and GM. The survival OHCs were then normalized to 100 μm length to further compare between different experimental conditions. 2B) OHC survival (OHC number per 100 μm length of cochlear middle turn) after treatment with Momelotinib at 0.0016, 0.008, 0.04, 0.2, 1.0, 5.0, 10.0 and 20.0 μM for 1 hour and co-incubated with 100 μM GM for 1 hour, or co-incubated with 600 μM kanamycin (K0254, Sigma) for 1 hour. (Mann-Whitney U Test, *P<0.05, **P<0.01). Quantification of outer hair cells from immunofluorescent images shows that cotreatment with Momelotinib grants full protection against aminoglycoside-induced hair cell loss (n=5 per group, student's t-test). *P<0.05, data shown as mean±standard error in all panels. - Now referring to
FIG. 3A-C , Momelotinib protects from aminoglycoside induced hair cell loss in zebrafish lateral line neuromasts in vivo. Zebrafish lateral line neuromast HC counts are commonly used in vivo models for screening otoprotectants. Danio rerio experimental larvae were obtained by pair mating of adult fish maintained at Creighton University by standard methods approved by the Institutional Animal Care and Use Committee. We used Tg(pou4f3:mGFP) expressing a membrane bound GFP in HCs. Experimental fish were maintained at 28.5° C. in E3 media (5 mM NaCl, 0.17 mM KCl, 0.33 mM CaCl2 and 0.33 nM MgSO4, pH 7.2). Animals were cryoanaesthetized after drug treatment and prior to fixation. The neuromasts inspected, SO3 and O1-2, were part of the cranial system and included the otic, middle, and opercular neuromasts. The lateral-line neuromasts of zebrafish are a valuable system for testing protectivity of compounds against aminoglycoside toxicity in vivo, as their HCs are considered homologous to those in the mammalian inner ear and are readily accessible to drugs. For the screenings, 5-day post-fertilization (dpf) Tg(brn3c:GFP) larvae were pre-incubated with Momelotinib at 0.002, 0.018, 0.165, 1.48, and 13.3 μM for 1 hour followed by co-incubation with either 200 μM KM for 1 hour, 150 μM KM for 6 hours, or 100 μM GM for 1 hour. DMSO at μM was used as a control. - Subsequently, animals were transferred to E3 water for 5 hours and fixed in 4% paraformaldehyde (PFA) overnight (26). Neuromast HCs were immunolabeled with anti-otoferlin (HCS-1, DSHB) and anti-GFP (NB100-1614, Novus Biologicals). These two markers were used to detect and count neuromast HCs to reduce the chances of missing some of the HCs after the treatment since we previously noticed that incubation with the compounds can affect GFP expression more difficult to detect under a fluorescence microscope (26). Otic, middle, and opercular neuromasts were identified, and HCs at SO3 (supraorbital line neuromast) and O1-2 (Otic line neuromasts) were manually counted using a Zeiss AxioSkop 2 fluorescence microscope with a 40× oil objective. Compounds were then evaluated on efficiency and potency, with the top-rated compounds showing high protection at lower concentrations.

DMSO at μM was used as a control. Additionally, 5-day post-fertilization (dpf) Tg(brn3c:GFP) larvae were pre-incubated with Fedratinib at, 0.018, 0.165 μM for 1 hour without being followed by co-incubation with KM. - Now referring to
FIG. 5 , Momelotinib showed no inner ear toxicity in C57BL/6 mice. 4-week-old C57BL/6 mice obtained from The Jackson Laboratory were used, with a mix of males and females across experiments.
