GILT study: Oral vinorelbine (NVBo) and cisplatin (P) with concomitant radiotherapy (RT) followed by either consolidation (C) with NVBo plus P plus best supportive care (BSC) or BSC alone in stage (st) III non-small cell lung cancer (NSCLC): Final results of a phase (ph) III study.

7001 Background: Concurrent chemo-radiotherapy (CT-RT) is considered as a standard in st III NSCLC. Published trials with C after CT-RT show encouraging but discordant results. This ph III was set up to assess C in st III NSCLC. Methods: Patients (pts) received NVBo 50 mg/m² D1, D8, D15 + P 20 mg/m² D1-D4 q4w / 2 cycles (cy) + RT (66 Gy / 33 Fr). C for OR+SD pts: NVBo 60-80 mg/m² D1D8 + P 80 mg/m² D1 q3w / 2 cy + BSC (Arm A) or BSC (Arm B). PFS was the primary endpoint. Results: From 07/05 to 05/09, 279 pts received CT/RT and 201 pts (72%) were randomised to receive CT+BSC or BSC as C. Toxicity (tox) G3-4 (% pt) CT-RT/ C (Arm A/B): anaemia 3.2/3.5/1.1; thrombopenia 2.5/1.2/0.6; neutropenia (N) 11.2/11.7/5.7; febrile N 1.4/1.0/0; nausea (G3) 5.0/4.7/2.9; vomiting (G3) 3.9/3.5/2.0; anorexia 3.6/1.2/3.0; dysphagia 1.8/2.3/1.0; fatigue 3.3/ 2.3/1.0; pneumonia/ pneumonitis 2.6/0/2.0; CT-RT pain 2.2; CT-RT oesophagitis 8.6; 3 toxic deaths. Conclusions: In this ph III, NVBo+P+RT reports a high level of efficacy ...
