On September 7, 2016, Retrophin Inc. released the “Top Line” results from their recently completed DUET study, a Phase 2 clinical trial testing safety and efficacy of Sparsentan for FSGS patients.

Results showed promise for Sparsentan’s effectiveness at reducing proteinuria in patients with FSGS, with one group of patients seeing an average reduction of 44.8%. The DUET study included 96 patients, and only one serious adverse side effect (anemia) was reported. All patients chose to extend their treatment with Sparsentan during the trial’s open label extension period.

Alvin Shih MD, the executive vice-president for Retrophin Inc., said “significant reductions in proteinuria, along with a well-tolerated preliminary safety profile have us excited about being one step closer to providing a new treatment option for patients with FSGS.”

NephCure Kidney International is excited about these results and support Dr. Shih’s hope that we are moving closer to providing a new, effective, and safe treatment option for FSGS patients. Mark Stone, Chief Executive Officer of NephCure Kidney International, remarked “These preliminary results are very exciting for our community. This gives us hope that better treatment options will be available for our families in the near future.”

NephCure Kidney International would like to thank everyone who contributed time, talent, and resources to this study.  Thank you, especially, to the patients and families who participated and helped bring effective treatments within reach.
