Genentech provides update on phase II/III Skyscraper-06 study in metastatic non-squamous non-small cell lung cancer.
Genentech, a member of the Roche Group, announced that the Phase II/III SKYSCRAPER-06 study, evaluating tiragolumab plus Tecentriq (atezolizumab) and chemotherapy versus pembrolizumab and chemotherapy as an initial (first-line) treatment for people with previously untreated, locally advanced unresectable or metastatic non-squamous non-small cell lung cancer (nSq NSCLC), did not meet its primary endpoints of progression-free survival (PFS) at its primary analysis with a hazard ratio (HR) of 1.27 [95% CI: 1.02,1.57] and overall survival (OS) at its first interim analysis with a HR of 1.33 [95% CI: 1.02, 1.73], which was immature
The combination of tiragolumab plus Tecentriq and chemotherapy showed reduced efficacy in both PFS and OS compared to the comparator arm in the intent-to-treat population, which includes Phase II and Phase III cohorts. The overall safety profile remains consistent with the safety profile previously observed for the combination of tiragolumab plus Tecentriq and chemotherapy, and no new or unexpected findings were identified. Based on these results, patients and investigators will be unblinded and we intend to halt the study. A communication will be sent to the investigators and results will be shared with health authorities and subsequently presented at an upcoming medical meeting.
