Gilead Sciences, Inc. and MiroBio, a privately-held U.K.-based biotechnology company focused on restoring immune balance with agonists targeting immune inhibitory receptors, today announced that the companies have entered into a definitive agreement pursuant to which Gilead will acquire MiroBio for approximately $405 million in cash, subject to customary adjustments.
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 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.
“The team at MiroBio has spearheaded foundational research for agonist antibodies following a rigorous scientific approach,” said Flavius Martin, Executive Vice President, Research, Gilead Sciences. “We believe that MiroBio’s unique platform technology has the potential to produce best-in-class agonist antibodies targeting immune inhibitory receptors.”
“We are excited to be joining Gilead. MiroBio has a deep understanding of checkpoint receptor signaling and a proprietary approach to select and generate superior agonist antibodies. Combining this with Gilead’s drug development and therapeutic area expertise will allow us to fully explore the potential of checkpoint agonist antibodies for patients with autoimmune disease.”
Eliot Charles, Chairman of MiroBio
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. Beginning in the first quarter of 2022, consistent with recent industry communications from the U.S. Securities and Exchange Commission (SEC), Gilead no longer excludes acquired IPR&D expenses from its non-GAAP financial measures. We expect the transaction with MiroBio to reduce Gilead’s GAAP and non-GAAP 2022 EPS by approximately $0.30-$0.35. Closing of the transaction is subject to expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.
About MiroBio
MiroBio is a clinical-stage private biotechnology company whose mission is to develop a new class of therapeutic agents, checkpoint agonist antibodies, to restore immune balance in autoimmune patients. MiroBio has developed I-ReSToRE, a proprietary discovery platform, combining its Checkpoint Atlas™, a cutting-edge receptor mapping database and visualization tool, with proprietary antibody engineering. It 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.
