Mereo BioPharma Group plc, a London-based biopharmaceutical firm established in 2015, specializes in developing and commercializing innovative therapies for oncology and rare conditions. Operating both in the United Kingdom and internationally, the company boasts a diverse product pipeline. Its primary oncology asset, etigilimab (OMP-313M32), an antibody T-cell immunoreceptor, is presently undergoing Phase 1b clinical investigation for tumor treatment. Another cancer compound, Navicixizumab (OMP-305B83), has already concluded its Phase 1b clinical studies for patients battling late-stage ovarian cancer. Beyond cancer, Mereo is advancing several other promising candidates. These include Acumapimod (BCT-197), a p38 MAP kinase inhibitor, which is currently in Phase II clinical trials for addressing acute exacerbations of chronic obstructive pulmonary disease. Additionally, Leflutrozole (BGS-649), an oral aromatase inhibitor, is being developed to manage hypogonadotropic hypogonadism. Within its rare disease portfolio, Mereo features Setrusumab (BPS-804), a novel antibody designed to treat osteogenesis imperfecta, and Alvelestat (MPH-966), an oral small molecule in Phase II clinical trials for Alpha-1 antitrypsin deficiency. To bolster its research, Mereo BioPharma collaborates with The University of Texas MD Anderson Cancer Center, focusing on the evaluation of its anti-TIGIT therapeutic antibody candidate, etigilimab.
