Shares of Otonomy Inc. plummeted 54%, to 12 cents, on Thursday after it said higher doses of its hearing-loss therapy didn't demonstrate meaningful improvement for patients across multiple speech-in-noise hearing tests.
The biopharmaceutical company said the clinical evaluation was of higher doses for OTO-413. The results compare with the positive clinical results observed with lower doses of the therapy versus a placebo in prior studies.
The company said the lack of activity may be due to a complex dose-response relationship that has been observed with neurotrophins.
Otonomy said it intends to explore strategic options to advance and realize value from its pipeline, including OTO-413 and OTO-825, its gene-therapy program for congenital hearing loss.
Shares were 94% lower for the year.
