Pacitaxel (Taxol®) was recently tested in patients with relapsed and refractory lymphoma in two phase II clinical trials using two different infusion schedules. The first, reported from the NCI (USA), used a 96-hour intravenous continuous infusion schedule, and the second, from our group, used a 3-hour infusion. In the NCI trial, 29 evaluable patients were treated with 140 mg/m2 every three weeks, which achieved a 17% response rate (all PRs); while we treated 96 evaluable patients with 200 mg/m2 every three weeks, which achieved a 25% response rate (10 CRs and 14 PRs, 95% CI: 17%–35%). In our trial, patients with relapsed (not primary refractory) intermediate-grade lymphoma had a response rate of 50%, and those with relapsed lowgrade lymphoma had a response rate of 31%. In a follow-up trial, 12 patients who failed to respond to 3-hour infusion of paclitaxel were crossed over to receive pacitaxel by 96-hour infusion. None of the 12 evaluable patients achieved a major clinical response. Similarly, of 25 patients treated with cyclosporine A and paclitaxel after failing therapy with single-agent paclitaxel, only one patient (4%) responded. We conclude that paclitaxel has a promising single-agent activity, most prominently in patients with relapsed intermediate-grade lymphoma. Paclitaxel-based combination programs are currently being evaluated in our institution.
