Anaptys Announces Third Quarter 2025 Financial Results and Provides Business Update

globenewswire.com

SAN DIEGO, Nov. 04, 2025 (GLOBE NEWSWIRE) -- AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics, today reported financial results for the third quarter ended September 30, 2025, and provided a business update.

“Our intent to separate our wholly owned biopharma programs from our royalty assets provides investors with the opportunity to realize and enhance the potential value of two distinct sets of assets. Jemperli sales grew to $785 million YTD with GSK indicating dMMR endometrial market share is now ~5% greater than Keytruda 1, reflecting Jemperli’s differentiated overall survival data and supporting GSK’s peak sales guidance of far more than $2.7 billion 2 in monotherapy indications,” said Daniel Faga, president and chief executive officer of Anaptys. “Our biopharma portfolio is strategically positioned with multiple attractive, high-potential assets, including rosnilimab, ANB033 and ANB101. Rosnilimab’s transformational profile was highlighted in a late-breaking presentation of Phase 2b data in RA at ACR Convergence 2025 and we anticipate reporting top-line Phase 2 data through Week 12 in ulcerative colitis in November or December.”
