Glenmark Therapeutics Expands Specialty Portfolio with OTIPRIO® Co-Promotion Agreement in the U.S. with Otonomy for Acute Otitis Externa Indication

MAHWAH, N.J., May 2, 2019 /PRNewswire/ -- Glenmark Therapeutics Inc., USA, a wholly-owned subsidiary of Glenmark Holding SA., today announced a co-promotion agreement with Otonomy, Inc. (OTIC), a biopharmaceutical company dedicated to the development of innovative therapeutics for neurotology. Glenmark Therapeutics is dedicated to developing and commercializing a franchise of branded products for Glenmark Pharmaceuticals and is focused in the areas of respiratory and dermatology. Ryaltris™ (olopatadine hydrochloride [665 mcg] and mometasone furoate [25 mcg]), formerly GSP 301 Nasal Spray, is the company's leading respiratory pipeline asset and currently under review with the U.S. Food and Drug Administration (FDA) as a treatment for seasonal allergic rhinitis in patients 12 years and older. "Ryaltris" has been conditionally accepted by the FDA as the brand name.

This agreement provides Glenmark Therapeutics with an exclusive right to promote OTIPRIO (ciprofloxacin otic suspension) for the treatment of acute otitis externa (AOE) in patients 6 months of age and older due to Pseudomonas aeruginosa and Staphylococcus aureus in ear, nose and throat specialist offices in the United States and its territories. Financial terms for the multi-year agreement were not disclosed; however, Glenmark Therapeutics will provide Otonomy an annual co-promotion fee and provide reimbursement of a proportion of product support expenses. In addition, Otonomy will retain a share of the adjusted gross profits from the sale of OTIPRIO to Glenmark's accounts. Commercial rights for use of OTIPRIO in other indications, including treatment of bilateral otitis media with effusion in patients 6 months and older who need ear tubes, will remain with Otonomy.

"We are pleased to collaborate with Otonomy on this agreement which represents an excellent opportunity to fit within our respiratory franchise and supports our strategy of maintaining commercial emphasis on specialists," said Robert Matsuk, President North America for Glenmark Therapeutics. "With FDA review of our first New Drug Application for Ryaltris well underway, we remain focused on developing new partnerships that bolster our specialty portfolio and commercial footprint in the U.S. This agreement is a clear example of Glenmark Therapeutics' efforts to maximize and grow our presence by pursuing opportunities both through external partnerships and our internal R&D pipeline."

About OTIPRIO
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).

Approved Indications for OTIPRIO
OTIPRIO (ciprofloxacin otic suspension) is a fluoroquinolone antibacterial indicated for

  • The treatment of pediatric patients 6 months of age and older with bilateral otitis media with effusion undergoing tympanostomy tube placement and
