SHANGHAI & SUZHOU, China & GERMANTOWN, Md.–(BUSINESS WIRE)–#CD39–Elpiscience Biopharmaceuticals, Inc. (“Elpiscience”), a clinical-stage biopharmaceutical company focused on developing next-generation immunotherapies to benefit cancer patients worldwide, today announced that the U.S. Food and Drug Administration (FDA) has cleared Elpiscience’s ES014 Investigational New Drug (IND) Application to initiate a Phase 1 clinical study for patients with advanced solid tumors. ES014 is a first-in-class anti-CD39xTGF-β bispecific antibody (bsAb) that simultaneously targets the CD39-adenosine and TGF-β pathways, two major immunosuppressive mechanisms in the tumor microenvironment (TME).
“We are delighted that our IND for ES014 was cleared by FDA,” said Steve Chin, Chief Medical Officer of Elpiscience. “ES014 is a first-in-class anti-CD39xTGF-β bispecific antibody. In preclinical studies, ES014 demonstrated significant anti-tumor activity in a PD-1 resistant in vivo efficacy model. We look forward to starting the Phase 1 study soon.”
Solid tumors frequently express TGF-β, which suppresses T cell activation and induces CD39 expression, the rate-limiting enzyme in the ATP-adenosine pathway. The anti-CD39 target is designed to selectively direct ES014 to the TME where the anti-TGF-β activity promotes effector T cell function and immune activation, while avoiding or minimizing systemic immunotoxicity. ES014’s anti-CD39 activity further aims to reverse TME immunosuppression by reducing suppressive adenosine, while maintaining high levels of immune-stimulatory extracellular ATP. The combined removal of immune suppression and immune stimulating effects of ES014 were recently demonstrated in a PD-1 antibody non-responsive in vivo animal model where tumor growth was significantly inhibited after treatment.
