Abstract

Purpose: We conducted a phase I trial of BNP7787 (disodium 2,2′-dithio-bis-ethane sulfonate, Tavocept™), a novel chemoprotective and antitumor enhancing agent administered in combination with paclitaxel and cisplatin. The primary aim was to determine a safe and potentially efficacious BNP7787 dose for preventing and mitigating paclitaxel- and cisplatin-induced toxicities and to evaluate for preliminary evidence of efficacy of treatment. Patients and methods: Twenty-two patients with stage IIIB/IV non-small cell lung cancer (NSCLC) received BNP7787 alone 1 week before co-administration of BNP7787 with paclitaxel followed by cisplatin. Twenty-one patients were treated with BNP7787 in escalating doses of 4.1-41.0 g/m 2 concurrently with paclitaxel 175 mg/m2 and cisplatin 75 mg/m2 every 3 weeks. Results: The appropriate dose was determined to be 18.4 g/m2 of BNP7787 although no dose-limiting toxicity was observed up to 41.0 g/m2. Mild intravenous site discomfort, thirst, and nausea were the most common toxicities. One patient developed grade 2 skin rash, which was severe enough to preclude further study treatment. The AUC 0-inf of the metabolite mesna was approximately 6.3% of the AUC 0-inf of BNP7787. Co-administration of paclitaxel and cisplatin did not appear to influence the pharmacokinetics of BNP7787 and mesna. The overall response rate was encouraging; 43% including 11 patients with prior chemotherapy. Conclusions: The recommended dose for phase II/III studies is 18.4 mg/m2 of BNP7787 in combination with paclitaxel and cisplatin. Further studies are warranted to assess whether BNP7787 prevents and mitigates common and serious paclitaxel- and cisplatin-related side effects and enhances the efficacy of paclitaxel and cisplatin in advanced NSCLC patients.
