FAILED TRIAL: Ph 3 SKYSCRAPER-01 study of tiragolumab + Tecentriq in patients with PD-L1-high 1L mNSCLC did not reach the primary endpoint of OS

“SKYSCRAPER-01 is a global phase III, randomised, double-blind study evaluating tiragolumab plus Tecentriq compared to Tecentriq alone in 534 patients with PD-L1-high previously untreated, locally advanced unresectable or metastatic NSCLC. Patients were randomised 1:1 to receive either tiragolumab plus Tecentriq or placebo plus Tecentriq, until disease progression, loss of clinical benefit, or unacceptable toxicity. The study did not reach the primary endpoint of overall survival at the final analysis. The overall safety profile observed remained consistent with longer follow-up, and no new safety signals were identified. The detailed data will be presented at a medical meeting in 2025.”

“Beyond the second-line monotherapy opportunity, we and our partners at Pfizer have removed plans for a Phase 3 first-line combination trial with atirmociclib, as well as the planned Phase 3 second-line combination trial with a CDK4/6 inhibitor, from our joint development plan,” continued Dr. Houston. “This decision was made following
“The interim PFS analysis results demonstrated that, compared to the current standard treatment, KN026 in combination with chemotherapy significantly improved PFS, reduced the risk of disease progression or death, and showed a trend toward OS benefit. Detailed data from this study will be presented at an upcoming international academic conference.”
