A late phase II clinical study of RP56976 (docetaxel) in patients with advanced or recurrent gastric cancer was performed to evaluate the anti-tumor activity and clinical toxicity as a multicenter cooperative trial. Docetaxel was administered intravenously at a dose of 60 mg/m2 every 3-4 weeks. Of 72 patients enrolled, 63 patients were eligible and 59 patients were evaluable for response. The anti-tumor effects obtained complete response (CR) in one patient partial response (PR) in 13, minor response (MR) in 3, no change (NC) in 20, and progressing disease (PD) in 22 patients. The overall response rate in 59 patients was 23.7% (14/59). For 14 CR or PR cases, a response appeared 10 to 107 days (median 33.5 days) and 1 to 8 (median 2) times of dosing after the initial administration. The response rate was 9.5% in the primary tumor, 31.3% livers, 50.0% abdominal tumor, and 24.1% lymph nodes, respectively. The major adverse reactions were gastrointestinal symptoms including nausea/vomiting, anorexia, fatigue, alopecia and fever. Leukocytopenia and neutrocytopenia were also observed with a high incidence, but they recovered after 8 days from the nadir. The results show that docetaxel is an effective anti-tumor agent for advanced or recurrent gastric cancer. It is necessary to conduct another clinical trial by concomitant administration with other anti-tumor agents.
