SAN DIEGO, Aug. 06, 2025 (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, 2025, and provided a business update.
"Rosnilimab's Phase 2b data in rheumatoid arthritis (RA) delivered a compelling safety and tolerability profile and JAK-like efficacy through six months that is durable for at least three months off-drug. The strength of the data, as well as positive feedback from the KOL community, gives us confidence in the transformational potential of rosnilimab. With enrollment completed in the Phase 2 ulcerative colitis (UC) trial, we look forward to reading out top-line data through Week 12 in Q4 2025, as well as potential additional six- and 12-month data from this trial in 2026," said Daniel Faga, president and chief executive officer of Anaptys. "Additionally, we are excited to announce the initial indication for our CD122 antagonist, ANB033, is celiac disease (CeD), a serious autoimmune disease triggered by the ingestion of gluten, affecting more than 2.1 million people in the U.S. but with no approved therapies. We believe ANB033's MoA, inhibiting both IL-2 and IL-15 signaling, is well-suited to target the multiple pathogenic drivers of CeD. We plan to initiate a Phase 1b cohort by Q4 2025 and will discuss the program in depth at a dedicated R&D event later this year."
PORTFOLIO UPDATES
Rosnilimab (Pathogenic T Cell Depleter)
Announced positive data for rosnilimab from robust, 424-patient Phase 2b RA trial demonstrating,
Best-in-disease profile with JAK-like efficacy and monthly (Q4W) dosing in both three-month placebo-controlled and six-month blinded treatment period
Favorable safety and tolerability, particularly when compared to standard of care biologics or JAK inhibitors
Max response rates have not yet been observed; strict continuation criteria at three months in this Phase 2b trial excluded many patients who either achieved or were trending toward LDA and ACR50
Trial now complete with CDAI LDA responders at Week 28 demonstrating durable responses for at least 12-14 weeks off drug through Week 38
Data consistent with previously reported partial data results through Week 34
Supports potential for maintenance dosing with extended dosing intervals (e.g. Q8W or Q12W)
Safety profile remains favorable and consistent with previously reported data
Plan to present complete RA Phase 2b data at a future medical congress
Enrollment complete for global Phase 2 trial in moderate-to-severe UC (N=136, ~50% advanced therapy experienced)
Assessing Q2W and Q4W dose levels of subcutaneously administered rosnilimab vs. placebo (randomized 1:1:1)
Primary statistical analysis at Week 12 on well-established endpoints, including the primary endpoint of change from baseline in modified Mayo score (mMS) and key secondary endpoints, such as clinical response and remission on mMS
All patients in all three study arms treat-through to Week 24 and remain blinded to treatment arm. Placebo-treated patients who achieved clinical response on partial modified Mayo score (pmMS) at Week 12 remain on placebo, while placebo-treated patients who are non-responders are crossed over to the high dose Q2W rosnilimab treatment arm
Patients who are in clinical response on pmMS at Week 24 are eligible for an additional 26-week (50 weeks of total treatment) blinded treatment extension period (TEP)
Top-line data through Week 12, including primary and key secondary endpoints, on track for Q4 2025
Blinded surveillance data to date suggest a favorable safety and tolerability profile consistent with prior rosnilimab trials
ANB033 (CD122 antagonist)
Phase 1 trial ongoing in healthy volunteers
Plan to initiate Phase 1b cohort for ANB033 in initial indication, celiac disease, by Q4 2025
Additional information to be disclosed at ANB033-focused R&D event in Q4 2025
ANB101 (BDCA2 modulator)
Phase 1 trial ongoing in healthy volunteers

FINANCIAL UPDATES
Stock Repurchase Program and Cash Runway
The Company has repurchased a total of 2,853,836 shares of common stock (9.3% shares outstanding) with $55.5 million as of June 30, 2025 from its $75.0 million Stock Repurchase Program
Cash and investments of $293.7 million as of June 30, 2025, and reiterating cash runway through year-end 2027
Second Quarter 2025 Financial Results
Cash, cash equivalents and investments totaled $293.7 million as of June 30, 2025, compared to $420.8 million as of December 31, 2024, for a decrease of $127.1 million due primarily to operating activities and $55.5 million in shares repurchased, offset by $15.0 million received from Vanda Pharmaceuticals for the license of imsidolimab.
Collaboration revenue was $22.3 million and $50.0 million for the three and six months ended June 30, 2025, compared to $11.0 million and $18.2 million for the three and six months ended June 30, 2024. This was due primarily to Jemperli royalties increasing $11.0 million and $22.1 million for the three and six months ended June 30, 2025 and $9.7 million in revenue recognized for the Vanda license agreement.
Research and development expenses were $37.8 million and $79.0 million for the three and six months ended June 30, 2025, compared to $42.0 million and $79.0 million for the three and six months ended June 30, 2024. The decrease for the three months ended June 30, 2025, was primarily due to lower development costs for ANB032 and imsidolimab offset by higher costs relating to the Phase 2 trials in RA and UC for rosnilimab and the Phase 1 trials for ANB033 and ANB101. The R&D non-cash, stock-based compensation expense was $4.5 million and $8.9 million for the three and six months ended June 30, 2025 as compared to $3.5 million and $7.0 million in the same period in 2024.
General and administrative expenses were $10.6 million and $24.7 million for the three and six months ended June 30, 2025, compared to $9.3 million and $21.6 million for the three and six months ended June 30, 2024. The increase was due primarily to transaction costs associated with the Vanda Pharmaceuticals license agreement. The G&A non-cash, stock-based compensation expense was $4.8 million and $9.5 million for the three and six months ended June 30, 2025 as compared to $4.0 million and $10.7 million in the same period in 2024.
Net loss was $38.6 million and $78.0 million for the three and six months ended June 30, 2025, or a net loss per share of $1.34 and $2.62, compared to a net loss of $46.7 million and $90.6 million for the three and six months ended June 30, 2024, or a net loss per share of $1.71 and $3.35.
