Phase 3 HARMONY Study of pegtibatinase enrollment progressing; topline results on track for the second half of 2027

SAN DIEGO, November 2, 2026 – Travere Therapeutics, Inc. (Nasdaq: TVTX) today reported its third quarter 2026 financial results and provided a corporate update.

“Strong execution across our business drove another quarter of significant growth, with FILSPARI net product sales of $200 million for the quarter as we continued to expand our reach in IgAN and FSGS,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “We remain early in reaching the more than 100,000 addressable patients across these conditions, reinforcing our confidence in FILSPARI’s substantial long-term opportunity. Alongside this commercial progress, we are advancing pegtibatinase toward pivotal Phase 3 results in the second half of next year and progressing civorebrutinib toward late-stage clinical development. As I prepare to transition leadership to Bradley Campbell in December, I have never been more confident in Travere’s future, supported by an exceptional team, an expanding pipeline and a shared commitment to delivering hope to patients.”
