MiroBio is a clinical-stage biotechnology startup operating out of the UK that discovers and develops therapeutic antibodies to restore balanced immune function and prevent further tissue damage. Its proprietary I-ReSToRE (Receptor Selection and Targeting to Reinstate Immune Equilibrium) platform features a checkpoint atlas of receptor expressions and function, antibody discovery process, and advanced bioinformatics. The firm’s technology was built on more than 15 years of checkpoint agonism research at the University of Oxford.
The firm has two main antibody drug candidates that are in the preclinical stage of the drug development process. MB272, the firm’s lead program, and MB151 are checkpoint receptor agonists targeting the proteins BTLA (B- and T-Lymphocyte Attenuator) & PD-1 (Programmed cell death protein 1), respectively, found in autoimmune diseases. Miro is also leveraging its I-ReSToRE platform to advance its pipeline of drugs focused on restoring immune homeostasis in patients with autoimmune diseases.
Key customers and partnerships
In August 2022, global biopharmaceutical company Gilead Sciences s igned a definitive agreement to acquire MiroBio for a cash consideration of USD 405 million. Post-acquisition, Gilead will have access to MiroBio's I-ReSToRE platform, and the entire portfolio of drug candidates. The pharma company plans to combine the I-ReSToRE platform with its existing R&D to treat autoimmune and inflammatory diseases and to expand its pipeline in the coming years.
Funding and Financials
The firm raised USD 97 million (GBP 80 million) in a Series B funding round led by Medicxi in June 2022. The funds were allocated toward advancing its lead antibody drug candidates MB272 and MB151 into clinical trials. The funds were also directed toward advancing its preclinical pipeline and building out its proprietary I-ReSToRE discovery platform.
