RESUMEN
PURPOSE: To study a commonly used Astragalus-based herbal formula previously found effective in non-small cell lung cancer (NSCLC) on the pharmacokinetics of docetaxel in patients with NSCLC. METHODS: Patients with advanced NSCLC who progressed after prior platinum-containing chemotherapy were accrued and received docetaxel at 35 mg/m(2) for 3 weeks followed by 1 week of rest. At 4 days prior to the second dosing, Jinfukang was given orally. Pharmacokinetic studies of initial-dose docetaxel (in the absence of Jinfukang) and the third dose (in the presence of Jinfukang) were compared. RESULTS: Of the 24 patients enrolled, 21 started Jinfukang and docetaxel. Jinfukang had no significant impact on the pharmacokinetics of docetaxel. Median time to progression or withdrawal from treatment was 7 weeks. Twelve patients were removed from study for progression of disease; nine patients withdrew. CONCLUSIONS: Jinfukang did not alter the pharmacokinetics of docetaxel nor appear to affect survival in this study.
