“Our findings represent a pivotal moment in the management of metastatic NSCLC. The extended survival and enhanced quality of life observed with nivolumab plus ipilimumab underscores the potential for a paradigm shift in treatment strategies,” said Dr. Solange Peters, Lausanne University Hospital in Switzerland.
The study enrolled adults with treatment- naïve stage IV or recurrent NSCLC, excluding those with known EGFR/ALK alterations and with ECOG performance status of ≤1. Patients were divided into different cohorts based on tumor PD-L1 expression levels and randomized to receive nivolumab plus ipilimumab, nivolumab, nivolumab plus chemotherapy or chemotherapy alone.
The latest data, with a minimum follow-up of 73.4 months, reaffirmed the compelling survival benefits of nivolumab plus ipilimumab over chemotherapy, Peters reported. Notably, the six-year overall survival rates were substantially higher, reaching 22% vs. 13% and 16% versus. 5%, respectively, for patients with tumor PD-L1 greater to or equal to 1% or less than 1%. These outcomes signify an advance in the treatment of metastatic NSCLC.
Additional endpoints, including objective response rates, duration of response, and quality of life, consistently favored the nivolumab + ipilimumab combination across all patient subgroups. Notably, responders with substantial tumor burden reduction exhibited considerably improved overall survival with nivolumab + ipilimumab compared to chemotherapy.
Furthermore, the study’s comprehensive assessment of patients’ health-related quality of life demonstrated a clear association between better baseline HRQoL and improved overall survival, regardless of the treatment received.
“The evidence we present offers a compelling case for the transformative potential of nivolumab plus ipilimumab in metastatic NSCLC treatment. Our findings underscore the significance of personalized care and better outcomes for patients,” said Dr. Peters.
