Pinetree Therapeutics
Pinetree Therapeutics is a Cambridge, Massachusetts biotech founded in 2019 that develops antibody-based targeted protein degraders for cancer. Its AbReptor and TAER-TAB platforms use modular bispecific and multispecific antibodies to hijack the body's own lysosomal machinery and eliminate disease-driving membrane-bound and extracellular proteins - including drug-resistant receptor tyrosine kinases that conventional inhibitors cannot reach. Led by founder and CEO Ho-Juhn Song, Ph.D., the preclinical company has raised roughly $111M to date, struck a $500M+ EGFR-degrader option deal with AstraZeneca, and is advancing lead oncology programs toward Phase I.
Prolium Bioscience
Prolium Bioscience is a New York-based, clinical-stage biotechnology company developing PRO-203, a bispecific CD20xCD3 T-cell engager designed to deplete disease-driving B cells as an off-the-shelf therapy for severe autoimmune diseases, starting with systemic sclerosis and lupus. Founded in 2025 and backed by RTW Investments, the company in-licensed global non-oncology and ex-Asia oncology rights to the antibody from China's InnoCare Pharma and KeyMed Biosciences, and launched publicly in March 2026 with a $50 million Series A alongside first-patient dosing.
Lyvgen Biopharma
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
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
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.
Jason Ehrlich
Jason Ehrlich is the co-founder and CEO of Ollin Biosciences, an Austin-based clinical-stage biopharma launched in September 2025 with $100 million to build best-in-disease eye medicines. An MD-PhD ophthalmologist trained at Princeton and Stanford, he spent a decade at Genentech/Roche helping shepherd retina drugs including Lucentis and the bispecific faricimab (Vabysmo), then served five years as chief medical and development officer at Kodiak Sciences. At Ollin he is taking direct aim at the market leader: in early 2026 his lead asset OLN324 beat faricimab head-to-head in a randomized Phase 1b study, drying retinas faster and deeper with a clean safety record.
克睿基因 Cure Genetics
克睿基因 Cure Genetics is a clinical-stage biotech founded in Suzhou in 2016 that develops cell and gene therapies for solid tumors and genetic diseases. It runs two proprietary platforms: AIMS, an allogeneic CAR-NKT cell therapy approach aimed at hard-to-treat solid tumors, and VELP, a directed-evolution AAV vector platform that builds high-quality viral libraries for tissue-targeted gene delivery to the nervous system, heart, and kidney. Its lead programs include CGC729 (anti-CD70 CAR-NKT for renal cell carcinoma) and CGC-602 (a PD-1-IL-2v bispecific antibody).
Marengo Therapeutics
Marengo Therapeutics is a Cambridge, Massachusetts clinical-stage biotech reprogramming the immune system from the inside out. Instead of releasing the brakes on T cells the way checkpoint inhibitors do, Marengo's STAR (Selective T Cell Activation Repertoire) platform builds antibody-fusion molecules that target variable regions of the T cell receptor (Vβ) to selectively wake up the specific subsets of T cells that can attack tumors - and remember them. Launched in 2021 with $80M from Apple Tree Partners, its lead drug invikafusp alfa (STAR0602) is in Phase 1/2 trials, has earned FDA Fast Track designation, and is being studied across cancers that no longer respond to PD-1 therapy.
Ollin Biosciences
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
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.
