A phase I-II study of gemcitabine and paclitaxel in advanced non-small- cell lung cancer patients

Thirty patients with chemotherapy-naive advanced non-small-cell lung cancer (NSCLC) were given escalating doses of paclitaxel (150, 175, 200 mg/m²) on day 1 in three consecutive cycles, together with a fixed dose of gemcitabine 1000 mg/m² on days 1 and 8; cycles were repeated every three weeks. The dose escalation of paclitaxel was feasible in the majority of patients. Subsequently, 30 other NSCLC patients received a dose of 200 mg/m² paclitaxel with gemcitabine 1000 mg/m² in a phase II study. The major side effect was mild myelosuppression. A response rate of 24% was achieved in 49 fully evaluable patients. This regimen proved to be safe and easy to administer on an out-patient setting, and constitutes now one of the arms of the current EORTC randomized study for advanced NSCLC.
