Otonomy Announces OTIPRIO® Data Presentation and Symposium at American Academy of Otolaryngology - Head and Neck Surgery Foundation Annual Meeting

Posted on: 13 Sep 16

SAN DIEGO, Sept. 13, 2016 (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 the upcoming presentation of results from an OTIPRIO® (ciprofloxacin otic suspension) Phase 2 trial in acute otitis externa (AOE), a potential label expansion indication, as well as the company’s sponsorship of a symposium related to OTIPRIO during the annual meeting of the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) to be held September 18-21, 2016 in San Diego.

Eric Mair, M.D., Charlotte Eye Ear Nose and Throat Associates, will present the OTIPRIO (development name OTO-201) Phase 2 trial results in AOE on Monday, September 19, in a presentation titled, “OTO-201 for the Treatment of Otitis Externa: Phase 2 Clinical Trial.” Preliminary results from this trial which enrolled a total of 75 pediatric and adult patients with unilateral AOE, also known as swimmer's ear, were announced in December 2015. This trial demonstrated the feasibility of administering OTIPRIO into the external ear canal of a patient in the physician office setting, and a clinical cure rate at both Day 8 and Day 15 of 80% or greater for patients treated with a 0.2 mL dose. These results served as the basis for a successful End-of-Phase 2 review by the U.S. Food and Drug Administration (FDA) which supported Otonomy's initiation of a single Phase 3 registration trial for OTIPRIO in patients with AOE that is expected to be completed by the end of 2016.

Otonomy Medical Affairs will be sponsoring a symposium and reception on September 20 titled, “Practice - and Payer - Perspectives on a Thermosensitive, Single-Dose, Ciprofloxacin Otic Suspension in Pediatric Patients Undergoing Tube Placement.” The symposium will review the burden of illness in pediatric patients undergoing tube placement, and discuss the clinical evidence from both registration and real-world clinical trials conducted with OTIPRIO.

“The AAO-HNSF annual meeting is the largest gathering of otolaryngologists during the year and therefore provides an excellent opportunity for continuing our efforts to establish physician awareness and advocacy to support the ongoing OTIPRIO commercial launch,” said David A. Weber, Ph.D., president and CEO of Otonomy. "We are particularly fortunate that the location of this year's meeting is in our hometown of San Diego which will facilitate our efforts to have a broad presence and high visibility to conference attendees."


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.
