Neurotology drug developer Otonomy (NSDQ:OTIC) has announced that its OTO-313 drug appeared to reduce tinnitus severity in some participants in a small study.
In the study, summarized in Otology & Neurotology, patients with moderate to severe unilateral tinnitus received intratympanic administration of the drug or placebo.
Six OTO-313 recipients out of 14 (43%) showed a meaningful improvement in Tinnitus Functional Index score at weeks four and eight of the study. Conversely, 13% of placebo recipients showed the same level of improvement.
