MILES-02: Study of Chemotherapy Treatment and Toxicity in Elderly Patients With Advanced Non Small Cell Lung Cancer

The study design includes three parallel phase II studies, all with the same rules for patient selection and outcome assessment. In the two studies of cisplatin-based doublets, a dose-finding phase is planned, with subsequent cohorts of 6 patients treated with increasing doses of cisplatin (50-60-70 mg/m²). Following this phase, patients will be assigned to the three studies through a randomization procedure, to reduce selection biases.

Arm A: gemcitabine:

Gemcitabine 1200 mg/m2 intravenously in 2 hours (10 mg/m²/minute) on days 1 & 8 of each cycle, every 21 days, for a maximum of 6 cycles.

Arm B: cisplatin + vinorelbine:

Vinorelbine 25 mg/m² on days 1 & 8, followed by Cisplatin (50 or 60 or 70 mg/m²) on day 1 of each cycle, every 21 days, for a maximum of 6 cycles.

Arm C: cisplatin + gemcitabine:

Gemcitabine 1000 mg/m2,, on days 1 & 8, followed by Cisplatin (50 or 60 or 70 mg/m²) on day 1 of each cycle, every 21 days, for a maximum of 6 cycles.
