Business Overview and History
AnaptysBio, Inc. (NASDAQ: ANAB) is a clinical-stage biotechnology company dedicated to developing innovative immunology therapeutics for autoimmune and inflammatory diseases. With a diversified pipeline and strategic collaborations, the company has positioned itself as a promising player in the rapidly evolving immunology landscape.
AnaptysBio was incorporated in the state of Delaware in November 2005 with a mission to leverage its proprietary technology platform to discover and develop novel antibody therapeutics. The company's approach focuses on modulating key nodes in the immune system to address a wide range of autoimmune and inflammatory disorders.
In its early years, AnaptysBio devoted its primary efforts to research and development activities, funded primarily through the sale of its common stock. The company faced challenges common to many biotechnology startups, such as the need to attract and retain highly skilled employees in a competitive market.
Over time, AnaptysBio has built a portfolio of antibody programs, including its lead program rosnilimab, which targets PD-1 T cells. In 2014, the company entered into a collaboration and exclusive license agreement with TESARO, Inc. (now part of GlaxoSmithKline) for the development of several of its product candidates in the immuno-oncology space, including the PD-1 antagonist Jemperli.
Throughout its history, AnaptysBio has financed its operations primarily through the sale of its common stock, royalty monetization transactions, and funds received under its collaborative research and development agreements. The company has faced both successes and challenges with its product candidates. In 2021, the FDA approved Jemperli for the treatment of certain endometrial cancers, providing the company with milestone and royalty payments from its collaboration with GlaxoSmithKline. However, the company has also encountered setbacks, such as the discontinuation of its ANB032 program for atopic dermatitis in 2024 after it failed to meet its goals in a Phase 2b study.
Over the past decade, AnaptysBio has steadily built a robust pipeline of product candidates, each targeting different immune cell types and pathways. The company's lead program, rosnilimab, is a depleter and agonist of PD-1+ T cells, which has demonstrated promising results in clinical trials for the treatment of moderate-to-severe rheumatoid arthritis (RA) and ulcerative colitis (UC).
In February 2025, AnaptysBio announced positive top-line data from the global Phase 2b RENOIR trial of rosnilimab in RA. The study met its primary endpoint, achieving statistical significance in the mean change from baseline in the Disease Activity Score-28 joints (DAS-28) C-Reactive Protein (CRP) score at Week 12 across all three doses of rosnilimab compared to placebo. Additionally, the trial demonstrated statistical significance on key secondary endpoints, including ACR20, ACR50, and Clinical Disease Activity Index (CDAI) low disease activity (LDA) at Week 12. Notably, the company reported the "highest ever" responses, with 69% of rosnilimab-treated patients achieving CDAI LDA at Week 14 and showing sustained CDAI LDA, ACR50, and potentially deepening ACR70 responses out to Week 28.
Alongside rosnilimab, AnaptysBio's pipeline includes other promising candidates, such as ANB033, a CD122 antagonist in a Phase 1 trial, and ANB101, a BDCA2 modulator, which is also entering a Phase 1 trial. These programs target different aspects of the immune system, broadening the company's potential to address a range of autoimmune and inflammatory conditions.
Financial Performance
As a clinical-stage biotechnology company, AnaptysBio has not yet generated significant revenue from product sales. However, the company has been successful in securing collaborations and royalty agreements that have provided a steady stream of non-dilutive funding.
