| Abstract: | Objectives. Tirapazamine (SR 4233) is a benzotriazine compound exhibiting substantial differential toxicity for hypoxic cells. A large enhancement in tumor cell killing has been demonstrated in preclinical studies when tirapazamine was combined with cisplatin. This phase I study was undertaken to establish a safe dose combination of tirapazamine and cisplatin when administered to patients with recurrent cervical carcinoma. Methods. Tirapazamine was administered as an intravenous infusion over 2 hr, followed 1 hr later by cisplatin intravenously over 1 hr, every 21 days. All patients received prophylactic antiemetics consisting of ondansetron, dexamethasone, and lorazepam. The planned dose escalation levels of tirapazamine were 195, 260, 330, and 390 mg/m2. The cisplatin dose was fixed at 75 mg/m2. Results. A total of 12 patients were treated with 43 courses of therapy. Patients were heavily pretreated. Eleven of the 12 had prior radiotherapy and 5 of the 12 had prior cisplatin-based chemotherapy. A maximally tolerated dose of 330 mg/m2 was defined for this patient population. The dose-limiting toxicity was nausea and vomiting. All 12 patients were also evaluated for response. Two major responses were seen (17%). In addition, there were three minor responses (25%) and 4 patients achieved disease stabilization (33%). All major and minor responses were seen at the highest dose level tested of 330 mg/m2. Conclusions. Tirapazamine and cisplatin is an interesting drug combination in the treatment of cervical cancer. Phase II testing is planned. |
