Feb 2025Series CNew Enterprise Associates (lead)$200M$1.2BAbcuro is a clinical-stage biotechnology company developing therapies for autoimmune diseases and cancer through precise modulation of cytotoxic T cells. The company's lead candidate, ulviprubart (ABC008), is a first-in-class monoclonal antibody targeting KLRG1, designed to selectively deplete cytotoxic T cells. Abcuro has received FDA orphan drug designation for ABC008 in inclusion body myositis (IBM), a progressive and debilitating inflammatory skeletal muscle condition with no available pharmaceutical therapies. The company is also advancing ABC015, an anti-KLRG1 blocking antibody capable of reactivating inhibited cytotoxic T and NK cells in the tumor microenvironment. On February 12, 2025, Abcuro closed a $200 million Series C financing round at a $1.2 billion post-money valuation. The round was led by New Enterprise Associates (NEA), with Foresite Capital joining as a new investor and participation from existing investors including RA Capital Management, Bain Capital Life Sciences, Redmile Group, Samsara BioCapital, Sanofi Ventures, Pontifax, Mass General Brigham Ventures, New Leaf Ventures, funds managed by abrdn Inc., funds and accounts managed by BlackRock, Eurofarma Ventures, and Soleus Capital. This represented significant investor confidence in the company's clinical program and market opportunity. Proceeds from the Series C are designated to support completion of the registrational Phase 2/3 MUSCLE trial of ulviprubart in inclusion body myositis, biologics license application (BLA) filing, commercial launch preparation, and expansion of manufacturing capabilities. The company's Phase 2/3 MUSCLE trial was expected to generate initial data in the first half of 2026. Abcuro is also overseeing a Phase 1/2 clinical trial of ulviprubart in T-cell large granular lymphocytic leukemia, expanding the therapeutic potential of the candidate across multiple indications with significant unmet clinical need. This $200 million Series C followed Abcuro's $155 million Series B in 2023, demonstrating sustained investor backing for the company's clinical-stage programs and proprietary discovery platform for identifying novel therapeutic targets in cancer and autoimmune diseases.

Its lead candidate, ABC008 (ulviprubart), is a first-in-class anti-KLRG1 monoclonal antibody designed to deplete cytotoxic T cells attacking healthy muscle tissue in inclusion body myositis (IBM), a progressive inflammatory condition with no approved therapies; it has FDA orphan drug designation. Abcuro is also advancing ABC015, an anti-KLRG1 blocking antibody to reactivate inhibited cytotoxic T and NK cells in the tumor microenvironment, and conducting a phase 1/2 trial in T-cell large granular lymphocytic leukemia. The company originates from research by Dr. Peter Greenberg at Fred Hutchinson Cancer Center, with Mass General Brigham Ventures and Sanofi Ventures leading an earlier Series A-1. In August 2023, Abcuro raised $155 million in an oversubscribed Series B financing round co-led by Redmile Group and Bain Capital Life Sciences, with participation from RA Capital Management, Samsara BioCapital, Sanofi Ventures (which co-led a prior $42 million Series A in 2021), and others including BlackRock, Eurofarma Ventures, Mass General Brigham Ventures, New Leaf Ventures, Pontifax, Soleus Capital, and Tekla Capital Management. An initial filing noted $120 million raised from a $200 million offering. The proceeds support advancement of ABC008 into clinical studies, building on prior funding to reach nearly $215 million total raised by then. Subsequently, in February 2025, Abcuro closed a $200 million Series C led by New Enterprise Associates with new investor Foresite Capital and existing backers, to complete the registrational Phase 2/3 MUSCLE trial of ulviprubart in IBM, expand manufacturing, and prepare for potential BLA filing and commercial launch, expecting initial data in H1 2026.

Its lead program, ABC008, is an anti-KLRG1 antibody designed to deplete pathogenic cytotoxic T cells attacking healthy tissue in autoimmune conditions, with a planned first-in-human proof-of-mechanism and safety trial in sporadic inclusion body myositis (IBM) patients. The company is also advancing ABC015, an anti-KLRG1 blocking antibody to enhance anti-tumor responses in oncology, supported by the Multiple Myeloma Research Foundation for multiple myeloma studies. In January 2021, Abcuro closed a $42 million Series A-1 financing round co-led by Mass General Brigham Ventures and Sanofi Ventures, with participation from Pontifax Venture Capital, Hongsen Investment Group, RA Capital Management, Samsara BioCapital, and others. This brought the company's total funding to nearly $60 million, following a $2.25 million seed in 2016, $8 million Series A in 2018, and $7.6 million from undisclosed investors in July 2020. Proceeds fund clinical advancement of ABC008 and preclinical oncology development. The round coincided with leadership appointments: John B. Edwards as Executive Chair and David de Graaf, Ph.D., as CEO. Jason Hafler from Sanofi Ventures, Iyona Rajkomar from Pontifax, Ryan Berry from RA Capital, and Donald McCarthy from Samsara BioCapital joined the board. Subsequent rounds included a $155 million Series B in 2023 co-led by Redmile Group and Bain Capital Life Sciences, and a $200 million Series C at $1.5 billion valuation led by RA Capital with Arch Venture Partners, but these postdate the queried round.
