Adapting maintenance strategy according to response to induction chemotherapy does not improve patient outcome in advanced non-squamous non-small cell lung cancer.
Background: Benefit from maintenance in advanced non-squamous non-sma l l cel l lung cancer (NS-NSCLC) might favor switch maintenance after disease stabilization (SD) and continuation after objective response (OR). This trial assessed a maintenance strategy conditioned by response to cisplatin-gemcitabine (CG) with G continuation for patients with OR or switch to pemetrexed (P) for patients with SD as compared with a control arm based on the Paramount regimen.Methods: Eligibility criteria: age 18-70 years, ECOG PS 0-1, untreated stage I V NS-NSCLC without EGFR orALK alteration, ineligibility to bevacizumab. Patients were randomized 1:1 to receive either CG (4 cycles) followed by G maintenance in case of OR followed by P at progression, or switch to P for patients with SD, or 4 cycles of C P followed by P (control arm). Prima r y endpoint: overa l l Survival. Results: Between 2012 and 2016, 932 patients were randomized (CG: 467, CP: 465) with well-balanced char-acteristics. 257 patients (56.7%) in the CG arm received maintenance (G: 142, P: 113) versus 277 patients (59.7%) in the CP arm. Median number of maintenance cycles was 5 for G and P (CG induction) and 4 for P (CP induction). OS adjusted HR was 0.97 (95% CI 0.84, 1.13; p = 0.71) with a median of 10.9 months (CG) versus 10.4 (CP). HR for PFS was 0.95 (95% CI 0.83, 1.09; p = 0.45) with a median of 4.8 months for CG versus 4.5 for CP. Safety profile was as expected.Conclusions: Adapting maintenance strategy according to response to induction chemotherapy does not improve patient outcome. Clinical trial information: NCT01631136.
