Raptor Announces Qualified Infectious Disease Product (QIDP) Designation for MP-376, Inhaled Levofloxacin
Granted for Three Distinct Indications: Chronic Pulmonary Infections Due to Pseudomonas Aeruginosa in Patients with Cystic Fibrosis and in Patients with Non-Cystic Fibrosis Bronchiectasis as well as in Patients with Nontuberculous Mycobacteria
Pre-NDA Discussion with FDA in Cystic Fibrosis Scheduled for 2Q 2016
NOVATO, Calif., March 16, 2016 (GLOBE NEWSWIRE) — Raptor Pharmaceutical Corp. (Nasdaq:RPTP) today announced that the U.S. Food and Drug Administration (FDA) has granted Qualified Infectious Disease Product (QIDP) designation to MP-376, the company’s proprietary inhaled levofloxacin, for three distinct indications: for the treatment of chronic pulmonary infections due to Pseudomonas aeruginosa, in patients with cystic fibrosis (CF) and in patients with non-cystic fibrosis bronchiectasis (BE), and in patients with nontuberculous mycobacteria (NTM).
Created under the Generating Antibiotics Incentives Now (GAIN) Act of 2012, the QIDP designation was established for the purpose of encouraging pharmaceutical companies to develop new antimicrobial drugs to treat serious and life-threatening infections. Granting of the QIDP designation by FDA highlights the potential of MP-376 to address a number of serious and life-threatening infections and provides Raptor with significant incentives for the development of MP-376, including priority review by the FDA, eligibility for Fast Track designation and a five-year extension of marketing exclusivity under the Hatch-Waxman Act. QIDP also paves the way for FDA to apply greater regulatory flexibility in the case of high unmet medical need for serious life-threatening infections. Raptor holds orphan designation in the U.S. for MP-376 for the treatment of CF, which, if granted after approval, confers seven years market exclusivity.
“We are pleased with the FDA’s decision to grant QIDP designation to MP-376 as we believe this drug has the potential to provide a significant benefit in the treatment of P. aeruginosa infections in patients with CF and in other chronic pulmonary infections in patients with bronchiectasis and nontuberculous mycobacteria,” said Krishna Polu, M.D., Chief Medical Officer of Raptor Pharmaceutical Corp. “Importantly, this designation validates the unmet need caused by a growing number of persistent lung infections which can result in death in these patients. QIDP designation will help to facilitate the development of MP-376 in these indications. We look forward to having regulatory discussions with the FDA in CF in the second quarter and initiating a Phase 2 program in bronchiectasis this year.”
About MP-376 (inhaled levofloxacin hemihydrate)
MP-376 is the investigational form of QUINSAIRTM, a proprietary inhaled formulation of levofloxacin, a fluoroquinolone antibiotic, which is being developed for the management of chronic pulmonary infections due to P aeruginosa in patients with CF in the U.S. QUINSAIR is approved in the EU and in Canada for the management of chronic pulmonary infections due to P. aeruginosa in adult patients with CF. MP-376 is also being developed for the treatment of non-CF bronchiectasis and NTM. Raptor plans to initiate a Phase 2 study in non-CF bronchiectasis by the end of 2016. Work to support further clinical development in lung infections associated with NTM is also planned. Administration of MP-376 with a high efficiency eFlow Nebulizer System (PARI Pharma GmbH) allows for the delivery of high concentrations of active drug directly to the site of infection in approximately five minutes.
