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.

OTO-104 is a formulation of the steroid dexamethasone in a gel that can be injected into the middle ear cavity.
“The gel holds the drug in the middle ear, and allows the drug to be solubolized [and absorbed] over time,” Weber said, easing symptoms of
