SAN DIEGO, Sept. 15, 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 successful completion of an open-label Phase 3b clinical trial that evaluated OTIPRIO® (ciprofloxacin otic suspension) in 501 pediatric patients with a history of otitis media requiring tympanostomy tube placement (TTP) surgery. The Phase 3b trial was designed primarily to evaluate OTIPRIO in a broader pediatric patient population than the previous Phase 3 trials by including patients undergoing common concurrent surgeries and patients without bilateral effusion on the day of surgery. The study also collected patient insurance information to evaluate differences in outcomes for patients with Medicaid versus commercial insurance, and assessed caregiver burden via a questionnaire.
Summary results of the Phase 3b OTIPRIO trial are as follows:
Full results from the trial will be presented at an upcoming medical conference.
“This study provides important information regarding the use of OTIPRIO in a patient population that reflects real-world clinical practice and further supports the utility of OTIPRIO administered as a single intraoperative dose by the physician,” said David A. Weber, Ph.D., president and CEO of Otonomy. “Furthermore, the benefit of assured compliance with OTIPRIO is highlighted by the increased caregiver burden associated with patients who required antibiotic ear drops, as well as by the similar outcomes measured regardless of the patient's insurance status. This last point is particularly noteworthy given the well-documented observation in other conditions, such as pediatric asthma, that medication adherence is lower and clinical outcomes are generally worse in the Medicaid patient population."
The open-label Phase 3b clinical trial enrolled a total of 501 pediatric patients at multiple centers throughout the United States. Patients received a single administration of OTIPRIO in each ear during TTP surgery. The clinical activity of OTIPRIO was measured through assessment of the presence of otorrhea, or drainage from the tube. Safety was assessed through adverse event reporting and otoscopic examinations over a two-month follow-up period. This trial also assessed caregiver burden associated with multi-dose, multi-day antibiotic ear drops in the subset of study patients who required ear drops in the post-operative follow-up period.
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.
