London and Redwood City, Calif., September 29, 2020 - Mereo BioPharma Group plc (NASDAQ: MREO, AIM: MPH), “Mereo” or “the Company”, a clinical stage biopharmaceutical company focused on oncology and rare diseases, today announces unaudited interim financial results for the six months ended June 30, 2020 and provides a corporate update.

Denise Scots-Knight, Chief Executive of Mereo, said: “Following the closing of our $70 million financing in the first half of 2020 we have focussed on executing our strategy, advancing etigilimab (“Anti-TIGIT”) for the treatment of solid tumors alongside developing our rare disease portfolio. We remain on track to initiate a Phase 1b/2 study of etigilimab (Anti-TIGIT) in combination with an anti-PD-1 in a range of solid tumor types in Q4 2020. Our rare disease portfolio includes setrusumab for osteogenesis imperfecta which we plan to partner prior to the initiation of a pivotal Phase 3 study, and alvelestat which is being investigated in an ongoing Phase 2 proof-of-concept study for alpha-1 anti-trypsin deficiency. We were also pleased to have recently announced the initiation of a Phase 1b/2 placebo-controlled study of alvelestat in COVID-19 infected patients following the scientific publications demonstrating the involvement of neutrophil elastase in COVID-19 infection pathways. We also continue to advance other discussions with potential partners to optimize the value of our broader product portfolio.”
