SAN DIEGO, July 18, 2017 (GLOBE NEWSWIRE) -- Otonomy, Inc. (Nasdaq:OTIC), a biopharmaceutical company focused on the development and commercialization of innovative therapeutics for diseases and disorders of the ear, today announced that its Supplemental New Drug Application (sNDA) for the approval of OTIPRIO® as a treatment of acute otitis externa (AOE) has been accepted for filing by the U.S. Food and Drug Administration (FDA) and been assigned a Prescription Drug User Fee Act (PDUFA) action date of March 2, 2018. The acceptance of the sNDA indicates that the application is sufficiently complete to permit a substantive review by the FDA.
“We are pleased to receive confirmation of the sNDA filing acceptance and PDUFA action date which is consistent with our expectations and previous investor communications,” said David A. Weber, Ph.D., president and CEO of Otonomy. “If approved within the standard review period, Otonomy anticipates a commercial launch of OTIPRIO for this second indication, which is primarily treated by physicians in the office setting, prior to the peak summer season for AOE.”
The sNDA is supported by positive results from a pivotal Phase 3 clinical trial of OTIPRIO in 262 pediatric and adult patients with AOE. This single administration trial of OTIPRIO met its primary endpoint showing a statistically significant increase in clinical cure rate compared to sham (no treatment) at Day 8 (p<0.001). OTIPRIO also demonstrated a statistically significant increase in clinical cure rate compared to sham 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.
About Acute Otitis Externa
Acute otitis externa (AOE), also known as swimmer’s ear, is a common condition involving infection and inflammation of the external ear canal typically caused by bacterial infection. According to medical claims data, there are nearly 4 million episodes of AOE each year in the United States. Symptoms usually appear within a few days of swimming and include itchiness, redness, swelling, pain and pus draining from the infected ear. Antibiotic ear drops are considered the standard of care treatment for AOE with the typical regimen requiring several administrations to the affected ear each day for 7 days.
OTIPRIO (ciprofloxacin otic suspension) is a fluoroquinolone antibacterial indicated for the treatment of pediatric patients with bilateral otitis media with effusion undergoing tympanostomy tube placement. OTIPRIO is administered by a physician as a single 0.1 mL (6 mg) intratympanic administration into each affected ear, following suctioning of the middle ear effusion. The thermosensitive suspension exists as a liquid at or below room temperature and gels when warmed. In two Phase 3 trials, a single intraoperative administration of OTIPRIO demonstrated a statistically significant reduction in the cumulative proportion of study treatment failures compared to tubes alone (p-value <0.001).
Important Safety Information for OTIPRIO
Contraindications: OTIPRIO is contraindicated in patients with a history of hypersensitivity to ciprofloxacin, to other quinolones, or to any of the components of OTIPRIO.
Warnings and Precautions - Potential for Microbial Overgrowth: OTIPRIO may result in overgrowth of nonsusceptible bacteria and fungi. If such infections occur, institute alternative therapy.
Adverse Reactions: Adverse reactions (incidence at least 3%) that occurred in two Phase 3 trials with OTIPRIO vs sham were: nasopharyngitis (5% vs 4%), irritability (5% vs 3%), and rhinorrhea (3% vs 2%).
Use in Specific Populations - Pediatric Use: The safety and effectiveness of OTIPRIO in infants below six months of age have not been established.

OTIPRIO® (ciprofloxacin otic suspension) is approved in the United States for use during tympanostomy tube placement surgery in pediatric patients, an sNDA has been accepted for filing by the FDA for acute otitis externa (AOE) and a successful End-of-Phase 2 meeting has been completed with the FDA for acute otitis media with tympanostomy tubes (AOMT). OTIVIDEX™ is a steroid in development for the treatment of Ménière's disease and other balance and hearing disorders. Two Phase 3 trials in Ménière's disease patients are ongoing, AVERTS-1 in the United States and AVERTS-2 in Europe, with AVERTS-1 results expected in the third quarter of 2017 and AVERTS-2 results expected by the end of 2017. In addition, a Phase 2 trial of OTIVIDEX is underway in patients at risk for cisplatin-induced hearing loss. OTO-311 is an NMDA receptor antagonist for the treatment of tinnitus that has completed a Phase 1 clinical safety trial with a Phase 2 trial expected to be initiated in the second half of 2017. A fourth program targeting sensorineural hearing loss including age-related hearing loss is in preclinical development.
