Following the outcomes of a hypothesis-generating examine of immunotherapy in glioblastoma, a sort of mind most cancers, a part 2 medical trial is about to judge Opdivo (nivolumab) with or with out relatlimab, a mix generally known as Opdualag, amongst sufferers with isocitrate dehydrogenase (IDH)-wildtype newly recognized glioblastoma (ndGBM).
