Gilead Sciences, Inc. (Nasdaq: GILD), a Foster City, California-based biopharmaceutical company, is to acquire MiroBio, an Oxford, England, U.K.-based biotechnology company focused on restoring immune balance with agonists targeting immune inhibitory receptors, for approximately $405m.
The acquisition will provide Gilead with MiroBio’s proprietary discovery platform and entire portfolio of immune inhibitory receptor agonists. MiroBio’s lead investigational antibody, MB272, is a selective agonist of immune inhibitory receptor B- and T-Lymphocyte Attenuator (BTLA) and has entered Phase 1 clinical trials, with the first patient dosed earlier this week. MB272 targets T, B and dendritic cells to inhibit or blunt activation and suppress an inflammatory immune response.
MiroBio’s I-ReSToRE platform (REceptor Selection and Targeting to Reinstate immune Equilibrium) has the potential to be used to develop best-in-class agonist antibodies targeting immune inhibitory receptors, a novel approach to the treatment of inflammatory diseases. The I-ReSToRE platform supports identification and development of therapeutics that utilize inhibitory signaling networks with the goal of restoring immune homeostasis for patients. Gilead anticipates advancing additional agonists derived from MiroBio’s I-ReSToRE platform, including a PD-1 agonist, MB151, and other undisclosed early-stage programs, over the next several years.
MiroBio was spun out of Oxford University in 2019 and is based on more than 15 years of foundational research from the labs of Professor Simon Davis and Professor Richard Cornall with the potential to create safer and more efficacious medicines for patients with autoimmune disease. MiroBio is backed by a strong group of international investors including Oxford Science Enterprises, Samsara BioCapital, SR One, Medicxi, Advent Life Sciences, OrbiMed and Monograph.
Under the terms of the agreement, Gilead will acquire all of the outstanding share capital of MiroBio for a total of $405 million in cash consideration, subject to customary adjustments, which is payable at closing.
