Otonomy announces phase 2b trial data for OTO-104 in Meniere’s disease

Otonomy, Inc, a clinical stage biopharmaceutical company developing innovative therapeutics for diseases and disorders of the inner and middle ear, announced topline results from its phase 2b trial evaluating OTO-104 in patients with unilateral Ménière’s disease. The primary endpoint of the trial was reduction in vertigo frequency during month 3 following treatment compared to a one month baseline period. In the topline analysis, OTO-104 demonstrated a 61 per cent reduction from baseline in vertigo frequency in month 3 vs. 43 per cent for placebo with a placebo (p value) of 0.067.

“While the trial narrowly missed achieving statistical significance on the primary endpoint, we believe the clear efficacy trends observed along with the multiple secondary endpoints where statistical significance was achieved provide a solid basis to move OTO-104 forward into phase 3 testing,” said David A. Weber, president and CEO of Otonomy. “We plan to request an end-of-phase 2 meeting with the US FDA and intend to initiate two parallel Phase 3 trials in Ménière’s disease with the first beginning by the end of 2015.”

OTO-104 was well tolerated in the study and no drug-related serious adverse events were observed. Persistent perforations of the tympanic membrane at the end of Month 4 were observed in 2.6 per cent of patients treated with OTO-104 which is consistent with the findings from the OTO-104 phase 1b trial as well as published results for trials utilizing intratympanic injection of steroid solutions.
