SAN DIEGO, March 11, 2024 (GLOBE NEWSWIRE) -- AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company focused on delivering innovative immunology therapeutics, today reported operating results for the fourth quarter and year ended December 31, 2023 and provided a business update.

"2023 was a remarkable year for Anaptys as we implemented a multi-year development plan investing across our best-in-class immune cell modulators (ICMs) to bring transformational medicines to patients living with heterogeneous, systemic autoimmune and inflammatory diseases, with the goal of restoring immune balance," said Daniel Faga, president and chief executive officer of Anaptys. "Enrollment is ongoing in three global Phase 2 trials for ANB032, our BTLA agonist, in atopic dermatitis and rosnilimab, our PD-1 agonist, in rheumatoid arthritis and ulcerative colitis. Additionally, we expanded our portfolio by acquiring the rights to ANB101, a BDCA2 modulator, which targets plasmacytoid dendritic cells, known to be key drivers of interferon secretion and antigen presentation."

"We will have a number of important events in 2024 including the top-line data readout of ANB032's Phase 2b trial in atopic dermatitis by year end," adds Faga. "We also plan to move our third and fourth ICMs -- ANB033, our anti-CD122 antagonist, and ANB101 -- into the clinic this year, with IND filings planned for Q2 and H2, respectively."
