"This quarter, we continued to enroll patients globally across three Phase 2 trials for our two best-in-class checkpoint agonists: ANB032, our BTLA agonist, and rosnilimab, our PD-1 agonist. By year end, we anticipate sharing top-line data from ANB032’s Phase 2b trial in atopic dermatitis, as well as moving our two pre-clinical immune cell modulators, ANB033 and ANB101, into clinical development," said Daniel Faga, president and chief executive officer of Anaptys. "Additionally, we are excited to further strengthen our balance sheet by adding $50 million through a capped non-recourse monetization of Jemperli royalties as well as share incremental data from the imsidolimab Phase 3 program."
Updates on Wholly Owned Immune Cell Modulator Pipeline
ANB032 (BTLA agonist antibody)
•Enrollment ongoing for global Phase 2b trial in moderate-to-severe AD
◦160 patient placebo-controlled trial assessing three dose levels of subcutaneously administered ANB032 (randomized 1:1:1:1) for a 14-week treatment duration and then followed for a six-month off-drug follow-up period
◦Reiterating top-line Week 14 data anticipated by year-end 2024
•Primary endpoint in Phase 2b trial to be updated from absolute change in EASI score to EASI-75 at Week 14, which is a well-accepted registrational endpoint that enables more relevant comparisons to benchmark therapies
•Presented posters on previously reported ANB032 preclinical data supporting the modulation of dendritic cell (DC) maturation and function and preclinical graft vs. host disease (GvHD) data at the 2024 American Academy of Dermatology (AAD) Annual Meeting in March 2024 and American Association of Immunologists (AAI) Annual Meeting in May 2024
•Poster presentations are available at View Source
Rosnilimab (PD-1 agonist antibody)
•Enrollment ongoing for global Phase 2b trial in moderate-to-severe RA

◦420-patient placebo-controlled trial assessing three dose levels of subcutaneously administered rosnilimab (randomized 1:1:1:1) for a 12-week treatment duration on well-established endpoints, including DAS28-CRP, CDAI and ACR20/50/70
▪At Week 14, rosnilimab-treated patients who achieve low disease activity, defined as CDAI<=10, are eligible to be dosed for an additional 16-week all-active treatment period and then followed for a three-month off-drug follow-up period
◦Reiterating top-line Week 12 data anticipated by mid 2025
•Enrollment ongoing for global Phase 2 trial in moderate-to-severe UC
◦130-patient placebo-controlled trial assessing two dose levels of subcutaneously administered rosnilimab (randomized 1:1:1) for a 12-week treatment duration on well-established endpoints, including clinical response on modified Mayo score (mMS), clinical remission on mMS and endoscopic remission
▪Rosnilimab and placebo-treated patients who achieved clinical response on mMS are eligible to continue on their assigned treatment for an additional 12 weeks, while patients on placebo who are non-responders will be crossed over to the high-dose rosnilimab treatment arm, in an all-active treatment period and then followed for a three-month off-drug follow-up period
◦Reiterating top-line Week 12 data anticipated by H1 2026
•Presented poster on previously reported rosnilimab Phase 1 data and membrane proximal binding epitope to optimize PD-1 agonist signaling at the 19th Congress of the European Crohn’s and Colitis Organisation (ECCO) in February 2024
◦Poster presentation is available View Source
ANB033 (anti-CD122 antagonist antibody)
•Plan to submit an Investigational New Drug (IND) application in Q2 2024
ANB101 (BDCA2 modulator antibody)
•Plan to submit an IND application in H2 2024
Updates on Legacy Clinical-Stage Cytokine Antagonist Programs Available for Out-Licensing
•Announced positive top-line results from its global GEMINI-1 and GEMINI-2 Phase 3 trials evaluating the safety and efficacy of investigational imsidolimab (IL-36R mAb) in patients with generalized pustular psoriasis (GPP)
◦See full press release at View Source
•Plan to submit a comprehensive data abstract for GEMINI-1 and GEMINI-2 to a H2 2024 medical meeting
•Intend to out-license imsidolimab in 2024

•GSK anticipates top-line data in 2025 from COSTAR Lung Phase 3 trial comparing cobolimab, a TIM-3 antagonist, plus dostarlimab, a PD-1 antagonist, plus docetaxel to dostarlimab plus docetaxel to docetaxel alone in patients with advanced NSCLC who have progressed on prior anti-PD-(L)1 therapy and chemotherapy
First Quarter Financial Results and Cash Runway
•Excluding the $50 million in proceeds from the capped non-recourse monetization of Jemperli royalties by Sagard, cash, cash equivalents and investments totaled $370.1 million as of March 31, 2024, compared to $417.9 million as of December 31, 2023, for a decrease of $36.9 million relating primarily to cash used for operating activities as well as a one-time non-operating cash payment of $10.9 million during the quarter.
◦Reiterating cash runway through year-end 2026
•Collaboration revenue was $7.2 million for the three months ended March 31, 2024, compared to $1.4 million for the three months ended March 31, 2023. The change is due primarily to increased royalties recognized for sales of Jemperli.
•Research and development expenses were $37.0 million for the three months ended March 31, 2024, compared to $35.0 million for the three months ended March 31, 2023. The increase was due primarily to development costs for rosnilimab, ANB032 and ANB033 offset by a decrease in development costs for imsidolimab. The R&D non-cash, stock-based compensation expense was $3.5 million for the three months ended March 31, 2024 as compared to $2.8 million in the same period in 2023.
•General and administrative expenses were $12.3 million for the three months ended March 31, 2024, compared to $10.8 million for the three months ended March 31, 2023. The G&A non-cash, stock-based compensation expense was $6.7 million for the three months ended March 31, 2024 as compared to $6.1 million in the same period in 2023.
•Net loss was $43.9 million for the three months ended March 31, 2024, or a net loss per share of $1.64, compared to a net loss of $44.3 million for the three months ended March 31, 2023, or a net loss per share of $1.58.
