Truway Health Inner Ear Regeneration & Hearing Restoration Trial

Inner ear disorders are a major cause of hearing impairment worldwide and may result from a variety of causes including acoustic trauma, infections, inflammatory processes, vascular compromise, or degenerative conditions affecting the cochlea and auditory nerve. Damage to sensory hair cells within the cochlea is a common mechanism leading to sensorineural hearing loss and tinnitus. In many cases, these cells do not regenerate naturally in humans, resulting in persistent hearing impairment.

The HEAR-RESTORE study is a translational research program designed to investigate diagnostic, monitoring, and investigational therapeutic approaches for individuals experiencing inner ear injury, tinnitus, and temporary or permanent hearing loss. The study focuses on improving the understanding of cochlear injury mechanisms and evaluating potential regenerative and protective strategies that may support auditory recovery.

Participants enrolled in the study will undergo comprehensive otologic and audiologic evaluations. Baseline assessments will include a detailed clinical history, otoscopic examination, and standardized hearing tests. Audiologic evaluations will include pure-tone audiometry to determine hearing thresholds across multiple frequencies, speech recognition testing, tympanometry to evaluate middle ear pressure and compliance, and otoacoustic emissions testing to assess cochlear hair cell function. Additional neuro-auditory testing such as auditory brainstem response (ABR) testing may be performed to evaluate auditory nerve conduction and central auditory pathways.

The study may also include advanced diagnostic tools such as vestibular function testing, imaging studies of the inner ear structures, and digital symptom monitoring to assess tinnitus severity and functional hearing ability in daily environments. These assessments allow researchers to characterize patterns of hearing impairment and track changes over time.

In addition to diagnostic assessments, the study may explore investigational strategies aimed at supporting inner ear repair and auditory recovery. Research areas of interest include regenerative medicine approaches that aim to restore or protect cochlear hair cells and auditory neurons. Investigational concepts may include biological therapies designed to stimulate endogenous repair pathways, neuroprotective agents that reduce inflammatory damage in the cochlea, and emerging regenerative technologies intended to support cellular repair within the inner ear environment.
