Background CameL phase 3 study demonstrated the superiority of camrelizumab plus chemotherapy over chemotherapy alone for progression-free survival in patients with previously untreated advanced non-squamous non-small-cell lung cancer (NSCLC) without EGFR/ALK alterations. Here, we present the 5-year outcomes.Methods Patients were randomized (1:1) and received 4–6 cycles of camrelizumab plus carboplatin and pemetrexed (n=205) or carboplatin and pemetrexed (n=207) every 3 weeks, followed by maintenance camrelizumab plus pemetrexed or pemetrexed only. Crossover from chemotherapy group to camrelizumab monotherapy was permitted after disease progression.Results Median time from randomization to data cut-off was 65.2 months (range, 59.7–72.2). HR for overall survival (OS) was 0.74 (95% CI 0.58 to 0.93; one-sided p=0.0043), and was 0.62 (95% CI 0.49 to 0.79; one-sided p<0.0001) after adjustment for crossover. Five-year OS rates were 31.2% (95% CI 24.7% to 37.9%) with camrelizumab plus chemotherapy versus 19.3% (95% CI 13.9% to 25.3%) with chemotherapy alone. Among the 33 patients who completed 2 years of camrelizumab, 5-year OS rate was 84.3% (95% CI 66.4% to 93.2%), and 5-year duration of response rate was 46.5% (95% CI 24.9% to 65.6%) in the 32 responders. No new safety signals were noted.Conclusions Camrelizumab plus carboplatin and pemetrexed as first-line therapy continued to demonstrate long-term OS benefit over carboplatin and pemetrexed, with manageable toxicity. Patients who completed 2 years of camrelizumab had enduring response and impressive OS. Current 5-year updated analysis further supports camrelizumab plus carboplatin and pemetrexed as a standard-of-care for previously untreated advanced non-squamous NSCLC without EGFR/ALK alterations.Trial registration number NCT03134872.
