Otonomy Announces OTIPRIO® Co-Promotion Agreement with Glenmark Therapeutics for Acute Otitis Externa Indication

SAN DIEGO, May 02, 2019 (GLOBE NEWSWIRE) -- Otonomy, Inc. (OTIC), a biopharmaceutical company dedicated to the development of innovative therapeutics for neurotology, today announced the signing of a co-promotion agreement with Glenmark Therapeutics Inc., USA, a wholly-owned subsidiary of Glenmark Holding SA., which is dedicated to building and commercializing a franchise of branded products for Glenmark Pharmaceuticals focused in the areas of respiratory and dermatology.

This agreement provides Glenmark Therapeutics with an exclusive right to promote OTIPRIO (ciprofloxacin otic suspension) to ear, nose and throat (ENT) physician offices in the United States and its territories for the treatment of acute otitis externa (AOE) in patients 6 months of age and older due to Pseudomonas aeruginosa and Staphylococcus aureus. Financial terms for the multi-year agreement were not disclosed; however, Otonomy will receive an annual co-promotion fee and reimbursement of a proportion of product support expenses, while retaining a share of the adjusted gross profits from the sale of OTIPRIO to Glenmark's accounts. Otonomy retains commercial rights for use of OTIPRIO in other indications including ongoing sales for use during pediatric ear tube surgery.

“We are excited to expand our promotional support for OTIPRIO in AOE by initiating this collaboration with Glenmark Therapeutics, which is part of a global pharmaceutical company with operations in more than 80 countries, and is committed to establishing a branded product commercial presence in the U.S.,” said David A. Weber, Ph.D., president and CEO of Otonomy. “Through this partnership and the ongoing co-promotion by Mission Pharmacal to pediatricians and primary care physician offices as well as urgent care clinics, we have established commercial support for OTIPRIO across all of the key physician groups involved in treating AOE in time for the peak 2019 season."


OTIPRIO is a sterile, preservative-free, otic suspension of 6% ciprofloxacin administered as a single-dose by a healthcare professional. The thermosensitive suspension exists as a liquid at or below room temperature and gels when warmed.

For bilateral otitis media with effusion, OTIPRIO is administered during ear tube surgery as a single 0.1 mL (6 mg) intratympanic administration into each affected ear, following suctioning of the middle ear effusion. 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).

For AOE, OTIPRIO is administered as a single 0.2 mL (12 mg) administration to the external ear canal of each affected ear. In a single Phase 3 trial, OTIPRIO demonstrated statistically significant clinical response defined as the complete absence of signs and symptoms of AOE (i.e., tenderness, erythema, edema, and otorrhea) compared to sham (p-value < 0.001).
