Otonomy Raises $49M to Advance 3 Drugs for Treating Ear Diseases

Otonomy, the San Diego biopharmaceutical startup developing new treatments for diseases and disorders of the ear, has refined its strategy, raised capital, and advanced three drug candidates in the three and a half years since David Weber stepped in as CEO.

And today Otonomy says it has secured $49 million in a new Series D round of financing that strengthens the balance sheet, diversifies Otonomy’s pool of investors, and moves the six-year-old startup closer to becoming a pre-commercial specialty drug company.

Today the company has 35, which is a reflection of the increasing number of drug candidates as well as the late-stage nature of Otonomy’s drug development, he said.

When Weber took over, Otonomy’s lead drug candidate, OTO-104, was in an early stage trial for use in patients with Meniere’s disease, a fluid imbalance of the inner ear that can cause dizziness and gradual hearing loss. OTO-104 is a formulation of the steroid dexamethasone in a gel that can be injected into the middle ear cavity.
