• Top-line data expected in December 2024 after having completed enrollment for Phase 2b trial to treat atopic dermatitis (AD) with ANB032, our BTLA agonist
  
• Top-line data accelerated and now anticipated in Q1 2025 for Phase 2b trial to treat rheumatoid arthritis (RA) with rosnilimab, our PD-1 agonist
• Top-line data now anticipated in Q1 2026 for Phase 2 trial to treat ulcerative colitis (UC) with rosnilimab

SAN DIEGO, Aug. 05, 2024 (GLOBE NEWSWIRE) -- AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics, today reported financial results for the second quarter ended June 30, 2024 and provided a business update.

“We’ve had an exceptional quarter as we approach multiple important value drivers for Anaptys including our first patient data for ANB032, our BTLA agonist. First, enrollment has completed in the Phase 2b trial of ANB032 in AD with strong demand leading to enrollment totaling approximately 200 patients. Importantly, we plan to share top-line Week 14 data in December of 2024,” said Daniel Faga, president and chief executive officer of Anaptys. “Second, strong demand in enrollment for the Phase 2b trial of rosnilimab in RA has accelerated anticipated top-line data from mid-2025 to Q1 2025. And finally, our IND for ANB033 was accepted by FDA in July and we look forward to initiating a Phase 1 trial in healthy volunteers soon. Looking to the end of the year, we still plan to have four immune cell modulators (ICMs) in clinical development.”

Second Quarter Financial Results

• Cash, cash equivalents and investments totaled $393.5 million as of June 30, 2024, compared to $417.9 million as of December 31, 2023, for a decrease of $24.4 million due primarily to cash used for operating activities offset by $50.0 million received from the Sagard royalty monetization completed in May.
• Collaboration revenue was $11.0 million and $18.2 million for the three and six months ended June 30, 2024, compared to $3.5 million and $4.8 million for the three and six months ended June 30, 2023. The change is due primarily to increased royalties recognized for sales of Jemperli.
• Research and development expenses were $42.0 million and $79.0 million for the three and six months ended June 30, 2024, compared to $32.9 million and $67.9 million for the three and six months ended June 30, 2023. The increase was due primarily to development costs for rosnilimab, ANB032, ANB033 and ANB101 offset by a decrease in development costs for imsidolimab. The R&D non-cash, stock-based compensation expense was $3.5 million and $7.0 million for the three and six months ended June 30, 2024, compared to $2.7 million and $5.5 million in the same period in 2023.
