GSK provides update on belrestotug development programme
GSK plc (LSE/NYSE: GSK), with its development partner iTeos Therapeutics, Inc., has confirmed it is ending the development programme for belrestotug, an anti-TIGIT monoclonal antibody. The decision is based on new interim analyses from the phase 2 GALAXIES Lung-201 and GALAXIES H&N-202 studies, which did not meet the established efficacy criteria for continued development. As a result, the collaboration and all belrestotug-containing study cohorts are ending.
