Retrophin Provides Sparsentan Regulatory Update; Reports Fourth Quarter And Full Year 2016 Financial Results

SAN DIEGO, March 01, 2017 (GLOBE NEWSWIRE) -- Retrophin, Inc. (NASDAQ:RTRX) today provided an update on the regulatory pathway for its late-stage product candidate sparsentan, and announced fourth quarter and full year 2016 financial results. Following guidance received from the U.S. Food and Drug Administration (FDA) during the Company’s End of Phase 2 meeting, the Company plans to initiate a single Phase 3 clinical trial to enable a New Drug Application (NDA) filing for sparsentan for the treatment of focal segmental glomerulosclerosis (FSGS). Notably, the trial will include an interim analysis of proteinuria as a surrogate endpoint to serve as the basis for an NDA filing for Subpart H accelerated approval of sparsentan. The confirmatory endpoint of the study will subsequently compare changes from baseline in estimated glomerular filtration rate, or eGFR. The Company is working with the FDA to finalize the study protocol and expects to initiate the trial in the second half of 2017.

“We are pleased to have received regulatory guidance from the FDA for sparsentan and look forward to working with them to finalize our Phase 3 study protocol and initiate this important trial later this year,” said Stephen Aselage, chief executive officer of Retrophin. “We are particularly encouraged by the agency’s alignment on the use of an interim analysis of proteinuria in this trial, which gives us an opportunity to expedite sparsentan’s path to approval. We are eager to build on the strong data from the Phase 2 DUET study to further demonstrate the significant potential of sparsentan in the treatment of FSGS.”
