Healthcare Industry News: transmembrane conductance regulator
News Release - April 4, 2018
Proteostasis Therapeutics Receives FDA Fast Track Designation for Triple Combination Program in Patients with Cystic FibrosisCAMBRIDGE, Mass., April 4, 2018 -- (Healthcare Sales & Marketing Network) -- Proteostasis Therapeutics, Inc. (NASDAQ: PTI), a clinical stage biopharmaceutical company dedicated to the discovery and development of groundbreaking therapies to treat cystic fibrosis (CF) and other diseases caused by dysfunctional protein processing, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for the Company's triple combination program for the treatment of cystic fibrosis. The Company's proprietary triple combination includes a novel cystic fibrosis transmembrane conductance regulator (CFTR) amplifier, third generation corrector and potentiator, known as PTI-428, PTI-801 and PTI-808, respectively. The Company announced in January that the protocol for its triple combination clinical study, which the Company plans to initiate in the current quarter, has received endorsement and a high strategic fit score from the Therapeutics Development Network (TDN) and the Clinical Trial Network (CTN), the drug development arms of the Cystic Fibrosis Foundation (CFF) and the European CF Society (ECFS), respectively.
"Fast Track designation represents another positive step for the development of our triple combination therapy and underscores the serious unmet need that remains for the vast majority of CF patients," said Meenu Chhabra, president and chief executive officer of Proteostasis Therapeutics. "We believe this designation, together with other recent designations from regulators and CF organizations following review of our results with PTI-428, PTI-801 and PTI-808, is recognition of the potential of these programs in this disease. We believe combinations of CFTR modulators hold the promise of improving treatment efficacy for different segments of the CF population, including F508del heterozygotes and F508del homozygotes, where patients have limited access to treatment, are underserved by existing treatments or see a declining benefit in lung function over time."
The FDA's Fast Track program is designed to facilitate the development and expedite the review of new drugs that are intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs. An investigational drug that receives Fast Track program designation is eligible for more frequent communications between the FDA and the company relating to the development plan and clinical trial design, and may be eligible for priority review if certain criteria are met.
About Triple Combination Therapy
Proteostasis Therapeutics is developing a combination treatment for CF through co-administration of three separate CFTR modulators: PTI-428, an amplifier, PTI-801, a corrector, and PTI-808, a potentiator. All three drug candidates were discovered internally at the Company and are designed to act synergistically through complementary mechanisms of action which address specific dysfunctions of the CFTR protein, the underlying cause of the disease. PTI-428, PTI-801, and PTI-808 have active INDs under the FDA and are currently in clinical trials in patients in the U.S. and Europe.
