Objective:
This study was designed to determine the maximum tolerated dose of paclitaxel administered weekly in combination with carboplatin and to assess its dose limiting toxicity and preliminary activity in patients with previously untreated, advanced non-small-cell lung cancer.
Methods:
Carboplatin was administered at a fixed dose that maintained an area under the curve of 6. Paclitaxel was given over 1 h once a week for 3 weeks starting at 60 mg/m(2) and escalated in 10 mg/m(2) increments.
Results:
Twenty-one patients were treated with six dose levels (60, 70, 80, 90, 100, 110 mg/m(2)) of paclitaxel. The dose limiting toxicity was infection and the maximum tolerated dose was 110 mg/m(2). Nine of 21 (42.9%) patients demonstrated a therapeutic response.
Conclusion:
Weekly paclitaxel and carboplatin were well tolerated. Based on our results, 100 mg/m(2) of paclitaxel for 3 weeks of a 4-week cycle, in combination with carboplatin, was recommended for a phase II study.
