SAN DIEGO, Feb. 17, 2018 (GLOBE NEWSWIRE) -- 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 that updated data from the company’s Phase 2a trial of ANB020, AnaptysBio’s wholly-owned anti-IL-33 antibody program, in adult patients with moderate-to-severe atopic dermatitis was presented today at the American Academy of Dermatology (AAD) Annual Meeting in San Diego. The oral presentation, titled “Proof-of-Concept Phase-2a Clinical Trial of ANB020 (Anti-IL-33 Antibody) in the Treatment of Moderate-to-Severe Adult Atopic Dermatitis” was presented by the principal investigator of the ANB020 Phase 2a clinical trial, Dr. Graham Ogg, professor of dermatology at Oxford University in Oxford, England, and is available through the publications section of the AnaptysBio website.
This Phase 2a proof-of-concept trial assessed ANB020 efficacy and safety in 12 moderate-to-severe adult atopic dermatitis patients. The primary efficacy objective of this study was to determine the percentage of patients achieving 50 percent improvement in their Eczema Area Severity Index (EASI) score relative to enrollment baseline (EASI-50) on day 29 post-ANB020 administration. Each patient was dosed with placebo 14 days following enrollment, and subsequently administered a single 300mg intravenous dose of ANB020 one week after placebo.
Key observations presented by Dr. Ogg during the aforementioned presentation included:
During the first half of 2018, AnaptysBio plans to initiate a Phase 2b randomized, double-blinded, placebo-controlled clinical trial in 200-300 adult patients with moderate-to-severe atopic dermatitis to evaluate various dose levels and dosing frequencies of subcutaneously-administered ANB020, with data expected in 2019.
ANB020 is an antibody that potently binds and inhibits the activity of interleukin-33, or IL-33, a pro-inflammatory cytokine that multiple studies have indicated is a central mediator of atopic diseases, including atopic dermatitis, food allergies and asthma. In addition to the aforementioned Phase 2a and Phase 2b clinical trials in moderate-to-severe adult atopic dermatitis patients, AnaptysBio has completed enrollment of a 20-patient randomized, double blinded, placebo-controlled Phase 2a trial in severe adult peanut allergy patients where top-line data are anticipated in March 2018 and is currently enrolling a 24-patient randomized, double blinded, placebo-controlled Phase 2a trial in severe adult eosinophilic asthma patients where top-line data are anticipated in the second quarter 2018.
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 (ANB020) for the treatment of moderate-to-severe adult atopic dermatitis, severe adult peanut allergy and severe adult eosinophilic asthma; its anti-IL-36R antibody (ANB019) for the treatment of rare inflammatory diseases, including generalized pustular psoriasis and palmo-plantar pustular psoriasis; and a portfolio of checkpoint receptor agonist antibodies for the treatment of certain autoimmune diseases where immune checkpoint receptors are insufficiently activated, which have demonstrated efficacy in an animal model of graft-versus-host disease. AnaptysBio’s antibody pipeline has been developed using its proprietary somatic hypermutation (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 and an inflammation partnership with Celgene, including an anti-PD-1 antagonist antibody (TSR-042), an anti-TIM-3 antagonist antibody (TSR-022) and an anti-LAG-3 antagonist antibody (TSR-033), which are currently under clinical development with TESARO, and an anti-PD-1 checkpoint agonist antibody (CC-90006) currently in the clinic with Celgene.
