Concert Pharmaceuticals Announces Successful End-of-Phase 2 Meeting with FDA for CTP-499
Provides Direction for Phase 3 Development in Diabetic Nephropathy
LEXINGTON, Mass.–(July 8, 2014)– Concert Pharmaceuticals, Inc. (NASDAQ:CNCE) today announced the successful completion of an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for CTP-499, its investigational therapy targeting diabetic nephropathy.
During the meeting, the FDA indicated general agreement with Concert’s proposed Phase 3 development plan providing flexibility to conduct either two clinical trials with CTP-499 or a single trial evaluating two doses of CTP-499 compared to placebo. A reduction in the rate of progression of renal disease, measured by a time-to-event analysis of the composite of increases in serum creatinine (greater than or equal to 50%) or end stage renal disease, versus placebo-treated patients, was agreed to be an acceptable Phase 3 endpoint to support the filing of a potential New Drug Application (NDA). The Company currently plans to submit a request for a Special Protocol Assessment (SPA) to the FDA later this year.
“We are very pleased with the outcome of the End-of-Phase 2 meeting and the feedback from our discussion with the FDA,” stated Roger Tung, Ph.D., President and Chief Executive Officer. “We believe the results from the Phase 2 clinical trial of CTP-499 in diabetic nephropathy are encouraging and appreciate the valuable guidance that the FDA has provided us regarding the design and conduct of a Phase 3 registration program.”
About Diabetic Nephropathy
Diabetic nephropathy, or type 2 diabetic kidney disease, a condition in which kidney function is progressively lost, can result in the need for dialysis or kidney transplantation. It is associated with increased morbidity and mortality, and is the leading cause of end-stage renal disease. The current standard of care for diabetic nephropathy is treatment with ACEis or ARBs, which are blood pressure lowering agents that affect the renin-angiotensin system. Despite the availability of these treatments, many patients progress to end stage renal failure and require dialysis or kidney transplants. Approximately 40% of patients with a history of type 2 diabetes are believed to have diabetic nephropathy.
About CTP-499
CTP-499 is a novel, deuterium-containing, oral anti-fibrotic agent. It is a multi-subtype selective PDE inhibitor that is being developed to slow the progression of diabetic nephropathy in patients with macroalbuminuria. CTP-499 is a deuterated analog of 1-(S)-5-hydroxyhexyl-3,7-dimethylxanthine, or HDX, an active metabolite of pentoxifylline. It is being developed as an additive treatment to angiotensin modulation with an ACEi or ARB. In April 2014, Concert announced 48-week results of its Phase 2 clinical trial of CTP-499 in patients with diabetic nephropathy which were presented in a late-breaking session at the National Kidney Foundation 2014 Spring Clinical Meeting.
About Concert
Concert Pharmaceuticals is a clinical stage biopharmaceutical company focused on applying its DCE Platform® (deuterated chemical entity platform) to create novel small molecule drugs. This approach starts with approved drugs, advanced clinical candidates or previously studied compounds that have the potential to be improved with deuterium substitution to enhance clinical safety, tolerability and efficacy. The Company is developing a broad pipeline targeting CNS disorders, renal disease, inflammation and cancer.
