Nutter is pleased that its client Abcuro, Inc., a clinical-stage biotechnology company developing therapies for autoimmune diseases and cancer through precise modulation of cytotoxic T and NK cells, recently closed a $42 million Series A-1 financing. Nutter provides legal counsel to Abcuro related to their expanding patent portfolio. The Nutter team is led by Kathy Williams, Ph.D., a partner in Nutter’s Intellectual Property Department and the co-chair of the firm’s Life Sciences practice group, and includes Amy DeCloux, Ph.D.  and Gurunathan Laxmikanthan, Ph.D.

The financing was co-led by Mass General Brigham Ventures and Sanofi Ventures, and included investors Pontifax Venture Capital, Hongsen Investment Group, RA Capital Management, and Samsara BioCapital, as well as others. Proceeds from this financing will be used to advance ABC008, an anti-KLRG1 antibody designed to deplete cytotoxic T cells that attack healthy tissue in a variety of autoimmune diseases. A first-in-human proof of mechanism and safety trial will be conducted in patients with sporadic inclusion body myositis (IBM) while additional indications are under investigation. IBM is a chronic and debilitating inflammatory skeletal muscle condition with no available pharmaceutical therapies. The Series A-1 proceeds will also support ongoing preclinical development of the company’s oncology program ABC015, an anti-KLRG1 blocking antibody capable of restoring effector cytotoxic T and NK cell function, resulting in a potent anti-tumor response. This includes financial and scientific support by the Multiple Myeloma Research Foundation to assess ABC015 in multiple myeloma. More information on the transaction.
