The International Association for the Study of Lung Cancer (IASLC) World Conference on Lung Cancer 2023 in Singapore is set to witness a monumental breakthrough in the field of metastatic non-small cell lung cancer (NSCLC) treatment.
Research findings from the CheckMate 227 trial will be presented, shedding light on the extraordinary six-year survival and quality of life benefits associated with first-line nivolumab + ipilimumab therapy.
CheckMate 227 Part 1 showed that a combination of first-line nivolumab and ipilimumab exhibited a remarkable and sustained survival advantage over traditional chemotherapy in patients with metastatic NSCLC.
"Our findings represent a pivotal moment in the management of metastatic NSCLC. The extended survival and enhanced quality of life observed with nivolumab + ipilimumab underscores the potential for a paradigm shift in treatment strategies," said Dr. Solange Peters, Lausanne University Hospital in Switzerland.
The study enroled adults with treatment- naive 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 tumour PD-L1 expression levels and randomised to receive nivolumab + ipilimumab, nivolumab, nivolumab + chemotherapy or chemotherapy alone.
The latest data, with a minimum follow-up of 73.4 months, reaffirmed the compelling survival benefits of nivolumab + ipilimumab over chemotherapy, Peters reported.
Notably, the six-year overall survival rates were substantially higher, reaching 22% vs. 13% and 16% vs. 5%, respectively, for patients with tumour PD-L1 ≥1% or <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 favoured the nivolumab + ipilimumab combination across all patient subgroups.
Notably, responders with substantial tumour 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 (HRQoL) 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 + ipilimumab in metastatic NSCLC treatment. Our findings underscore the significance of personalised care and better outcomes for patients,” said Dr. Peters.
