Travere sNDA for Filspari Full Approval
FDA has told Travere Therapeutics that data appear to support a supplemental NDA to convert the company’s accelerated approval to full approval for Filspari (sparsentan) in IgA nephropathy. Travere says it will submit a supplemental NDA in the first quarter of 2024 on the endothelin and angiotensin II receptor antagonist based on the feedback it recently received from FDA in a pre-NDA meeting.
In the meeting, Travere says it discussed its data on sparsentan for treating focal segmental glomerulosclerosis (FSGS). FDA told the company that its Phase 3 DUPLEX Study results alone are not sufficient to support an sNDA submission for this indication. “As a result, the company will be conducting additional analyses of FSGS data with plans to re-engage FDA in 2024,” Travere says.
