SAN DIEGO, Aug. 31, 2022 (GLOBE NEWSWIRE) — AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics, today announced top-line data from its HARP Phase 2 trial for the treatment of moderate-to-severe hidradenitis suppurativa (HS). The trial indicated imsidolimab was safe and well tolerated, however did not demonstrate efficacy over placebo in the trial’s primary endpoint and key secondary endpoints. Clinical development of imsidolimab is being discontinued in hidradenitis suppurativa.

“HS is a severely debilitating, painful and chronic skin disease with substantial unmet need. Although the results of this hidradenitis suppurativa trial are disappointing, we are very grateful to the patients, investigators and our employees involved in conducting this trial,” said Dr. Paul F. Lizzul, chief medical officer.

Imsidolimab previously demonstrated efficacy and safety in the GALLOP Phase 2 trial in generalized pustular psoriasis (GPP), a systemic, life-threatening inflammatory disease in which imsidolimab has been granted Orphan Disease Designation. Enrollment of the GEMINI-1 GPP Phase 3 registrational trial is ongoing and top-line data is anticipated in Q4 2023. The company plans to outlicense investigational imsidolimab prior to potential FDA approval for the treatment of GPP.

AnaptysBio also continues to advance the development of two wholly-owned immune cell modulators targeting PD-1 and BTLA for autoimmune and inflammatory disease. Top-line data from the AZURE Phase 2 trial of rosnilimab, a PD-1 agonist antibody, in moderate-to-severe alopecia areata is anticipated in the first quarter of 2023, and the company expects to file a U.S. IND for an initial Phase 2 trial of ANB032, a BTLA agonist antibody, in the fourth quarter of 2022.

“The IL-36 pathway plays a key role in the disease pathology of GPP. While we remain optimistic that imsidolimab, an IL-36 receptor antagonist, can meaningfully impact the treatment of patients with GPP, as part of our ongoing strategic portfolio review we have made the decision to complete execution of our Phase 3 program and outlicense imsidolimab prior to potential FDA approval,” said Daniel Faga, interim president and chief executive officer of AnaptysBio. “We’re well capitalized with over $570 million in cash at the end of Q2, and excited to focus on the R&D of our novel immune cell modulator pipeline, including our two checkpoint agonists in clinical-stage development, rosnilimab and ANB032. We believe their mechanisms of action, acting directly on cell types mediating disease pathology, have the potential to treat a broad range of autoimmune and inflammatory disorders.”

About AnaptysBio AnaptysBio is a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics. We are developing immune cell modulators, including two checkpoint agonists in clinical-stage development, for autoimmune and inflammatory disease: rosnilimab, our anti-PD-1 agonist program in Phase 2 for the treatment of moderate-to-severe alopecia areata; and ANB032, our anti-BTLA agonist program, which is broadly applicable to human inflammatory diseases associated with lymphoid and myeloid immune cell dysregulation. AnaptysBio is also developing imsidolimab, our anti-IL-36R antibody in Phase 3 for the treatment of generalized pustular psoriasis, or GPP. AnaptysBio’s antibody pipeline has been developed using our proprietary somatic hypermutation, or SHM platform, which uses in vitro SHM for antibody discovery and is designed to replicate key features of the human immune system to overcome the limitations of competing antibody discovery technologies. AnaptysBio has also developed multiple therapeutic antibodies in an immuno-oncology collaboration with GSK, including an anti-PD-1 antagonist antibody (JEMPERLI (dostarlimab-gxly) GSK4057190), an anti-TIM-3 antagonist antibody (cobolimab, GSK4069889) and an anti-LAG-3 antagonist antibody (GSK4074386).
