Abstrakt: Introduction: This phase II study assessed the efficacy and safety of oral vinorelbine given weekly in combination with carboplatin (CBDCA) AUC 5 once every 3 weeks for four cycles in chemonaive patients with advanced non-small cell lung carcinoma (NSCLC), followed by consolidation therapy with single-agent oral vinorelbine in non-progressive patients.
Methods: Chemonaive advanced NSCLC patients received four cycles of combination therapy with CBDCA AUC 5 day 1 and oral vinorelbine, 60 mg/m2 on days 1, 8 and 15 (cycle 1), dose increased to 80 mg/m2 (cycles 2-4) in absence of grades 3-4 neutropenia (NCI-CTCv2). Consolidation therapy with oral vinorelbine was continued (cycle 5) at same dosage; if dose was decreased during combination therapy, it was given at 60 mg/m2, then increased at 80 mg/m2 (cycle 6) in absence of grades 3-4 neutropenia until PD, toxicity or patient's refusal.
Results: A total of 57 patients were registered and 56 patients were treated (ITT population), median age was 61 years (37-71). Objective response evaluated by RECIST was 17.9% (95% confidence interval, CI [8.9-30.4]) and disease control (CR, PR, NC) 73.2% (95% CI [59.7-84.2]), median progression-free survival 4.3 months (95% CI [3.1-5.1]) with median overall survival 9.7 months (95% CI [7.7-11.9]) and 1-year survival 37.1% (95% CI [24.4, 49.9]). Grades 3-4 neutropenia occurred in 67.9% of patients during combination and 20% during consolidation; febrile neutropenia occurred in 4 patients (7.1%) during combination therapy. Non-hematological toxicities occurred primarily during combination (grade 3 nausea and grade 3 vomiting in 7.1% of patients).
Conclusions: The combination of oral vinorelbine given weekly in 3-week cycles in combination with carboplatin followed by consolidation therapy with oral vinorelbine as a single-agent was able to achieve efficacy results in line with other doublets including carboplatin in terms of response as well as survival. This regimen reported a good profile of tolerability in the treatment of advanced NSCLC, allowing that this combination can be easily proposed for the palliative care of NSCLC patients where the advantages of carboplatin over cisplatin are still appreciated.
