OTIPRIO® (ciprofloxacin otic suspension)

OTIPRIO is a physician administered, single dose formulation of ciprofloxacin in development for the treatment of patients with acute otitis externa, also known as swimmer’s ear, and patients with acute otitis media with tympanostomy tubes.

Acute Otitis Externa (AOE) Program

Recently, we submitted a Supplemental New Drug Application (sNDA) to the FDA for the use of OTIPRIO in the treatment of patients with AOE. The sNDA was based on positive results from a Phase 3 trial that evaluated a single administration of 12 mg OTIPRIO (equal to 0.2 mL) vs. sham (no treatment) in 262 pediatric and adult patients. In this trial, OTIPRIO met the primary endpoint by showing a statistically significant increase in clinical cure rate compared to sham at Day 8 (p<0.001) where clinical cure was defined as complete resolution of the signs and symptoms related to AOE. OTIPRIO also demonstrated a statistically significant superiority to sham in clinical cure rate at all other time points assessed including Day 4 (p=<0.021), Day 15 (p<0.001) and Day 29 (p<0.001), and was well-tolerated.

Acute Otitis Media with Tympanostomy Tubes (AOMT) Program

We have successfully completed a Phase 2 trial of OTIPRIO in pediatric patients with AOMT. This trial demonstrated that both OTIPRIO doses, 6 mg (0.1 mL) and 12 mg (0.2 mL), were well-tolerated and achieved higher and statistically significant (p<0.05) clinical cure rates over sham (no treatment). We believe this trial supports the advancement of OTIPRIO into Phase 3 in AOMT and intend to discuss the requirements for such a program with the FDA by the end of the second quarter of 2017.
