Lyvgen Biopharma is a Shanghai-based clinical-stage immuno-oncology company founded in 2016 by veteran oncology scientist Dr. Jieyi Wang. It builds agonist antibodies - drugs that switch the immune system on rather than release its brakes - using a proprietary xLinkAb platform designed to concentrate immune activation inside tumors while limiting toxicity elsewhere. Its lead program, the CD137/4-1BB agonist antibody LVGN6051 (exlinkibart), is in Phase Ib/II trials in the US and China, including combinations with Merck's Keytruda, alongside a CD40 agonist (LVGN7409), a PD-1 blocker (LVGN3616), and bispecific candidates. Backed by IDG Capital and others through a Series C, Lyvgen runs R&D in Shanghai, a CMC/manufacturing center in Suzhou, and clinical and business development teams spanning China and the US.
NEOK Bio is a Palo Alto-based clinical-stage biotechnology company developing bispecific antibody drug conjugates (ADCs) for solid tumors. Founded and led by physician-executive Mayank Gandhi and backed by Korean antibody specialist ABL Bio, NEOK launched from stealth in November 2025 with a $75 million Series A. Its dual-targeting approach binds two complementary tumor antigens at once, aiming to widen the therapeutic window and overcome the resistance and toxicity limits of conventional single-target ADCs. The company's two lead programs, NEOK001 (ROR1/B7-H3) and NEOK002 (EGFR/MUC1), both cleared FDA IND review in early 2026 and are headed into Phase 1 studies.
Fortitude Biomedicines is a Waltham, Massachusetts biotech that launched in early 2026 with $13M in seed financing to develop next-generation antibody-based therapies for autoimmune diseases and cancer. Its proprietary GLUE-DAC platform bolts molecular glue degraders onto antibody-drug conjugates, aiming to use catalytic targeted protein degradation to widen the therapeutic window of ADCs and overcome the resistance that has dogged the field. Its lead program, FORT-202, is a first-in-class T-cell targeting bispecific antibody for axial spondyloarthritis expected to reach the clinic in the first half of 2027.
Ollin Biosciences is an Austin-based clinical-stage biopharmaceutical company building a portfolio of best-in-disease therapies for vision-threatening eye diseases. Founded in 2023 and launched publicly in September 2025 with $100M in Series A financing, Ollin in-licenses validated drug candidates and races them through head-to-head trials against the market leaders. Its lead program, OLN324, is a VEGF/Ang2 bispecific antibody for wet age-related macular degeneration and diabetic macular edema that posted superior anatomic results versus Roche's blockbuster Vabysmo in a Phase 1b study.
Triveni Bio is a clinical-stage biotechnology company in Watertown, Massachusetts building first-in-class antibody therapeutics for immunological and inflammatory (I&I) diseases. Born from the 2023 merger of Amagma Therapeutics and Modify Therapeutics, the company pairs a genetics-informed approach with advanced antibody engineering to target root-cause biology rather than just downstream inflammation. Its lead program, TRIV-509, is a half-life-extended monoclonal antibody that inhibits active kallikreins 5 and 7 (KLK5/7) and is in a global Phase 2 proof-of-concept study for moderate-to-severe atopic dermatitis. Backed by roughly $223M across Series A and Series B rounds, Triveni aims to repair the skin barrier and break what it calls efficacy ceilings in dermatology and beyond.
