SAN DIEGO, CA, USA I November 08, 2019 I AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on unmet medical needs in inflammation, today announced topline data from its ATLAS trial, a Phase 2b randomized, double-blinded, placebo-controlled, multi-dose study in approximately 300 adult patients treated with etokimab in moderate-to-severe atopic dermatitis. Each of the etokimab dosing arms failed to meet the primary endpoint of the trial, which was demonstration of statistically greater improvement in the Eczema Area and Severity Index (EASI) relative placebo at week 16. The Company will be receiving additional data and plans to provide a detailed update in the first quarter of 2020.
As a result of this topline data, the Company has decided to postpone the initiation of its Phase 2b etokimab clinical trial in eosinophilic asthma, a multi-dose, randomized, double-blinded, placebo-controlled trial in 300-400 patients, until it has the opportunity to analyze the full data set from the ATLAS trial. The Company will continue conducting its ECLIPSE trial, a randomized, placebo-controlled Phase 2 trial in approximately 100 adult patients with chronic rhinosinusitis with nasal polyps, with topline data from an interim analysis expected in the first quarter of 2020.
“We are surprised and very disappointed by the topline results of the ATLAS trial,” said Hamza Suria, president and chief executive officer of AnaptysBio. “We would like to thank all involved in the participation and support of the ATLAS study, including the patients, the investigators, their staff and our employees. We look forward to continuing our strategy of advancing our wholly-owned clinical and preclinical pipeline programs.”
AnaptysBio is a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on unmet medical needs in inflammation. The Company’s proprietary anti-inflammatory pipeline includes its anti-IL-33 antibody etokimab, previously referred to as ANB020, for the treatment of moderate-to-severe atopic dermatitis, eosinophilic asthma, and adult chronic rhinosinusitis with nasal polyps, or CRSwNP; its anti-IL-36R antibody ANB019 for the treatment of rare inflammatory diseases, including generalized pustular psoriasis, or GPP, and palmoplantar pustulosis, or PPP; and its PD-1 agonist program, ANB030, and other novel anti-inflammatory checkpoint receptor modulator antibodies for treatment of certain autoimmune diseases where immune checkpoint receptors are insufficiently activated. AnaptysBio’s antibody pipeline has been developed using its 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 partnership with TESARO, a GSK company, including an anti-PD-1 antagonist antibody (dostarlimab (TSR-042)), an anti-TIM-3 antagonist antibody (TSR-022) and an anti-LAG-3 antagonist antibody (TSR-033), and an inflammation partnership with Celgene, including an anti-PD-1 checkpoint agonist antibody (CC-90006) currently in clinical development.
