Purpose To investigate the efficacy and safety of nitroglycerin plus vinorelbine and cisplatin in patients with previously untreated stage IIIB/IV non-small-cell lung cancer (NSCLC) as the experimental arm for the next phase III trial. Patients and Methods One hundred twenty patients with stage IIIB/IV NSCLC were randomly assigned to vinorelbine 25 mg/m(2) on days 1 and 8 and cisplatin 80 mg/m(2) on day 1, with transdermally applied nitroglycerin (25 mg/patient daily for 5 days; arm A) or with placebo patch (arm B) every 3 weeks for a maximum of four cycles in a double-blind and controlled trial. Primary efficacy end points were the best confirmed response rate and time to disease progression (TTP). Results The response rate in arm A (72%; 43 of 60 patients) was significantly higher than that for patients in arm B (42%; 25 of 60 patients; P < .001). Median TTP in arm A was longer than that in arm B (327 v 185 days). No severe adverse effect was recognized for either arm. The rate of grade 1 to 2 headache in arm A (30%; 18 of 60 patients) was significantly higher than that in arm B (2%; one of 60 patients; P < .001, chi(2) test). Conclusion Use of nitroglycerin combined with vinorelbine and cisplatin may improve overall response and TTP in patients with stage IIIB/IV NSCLC. The arm A regimen is being evaluated in a large phase III trial.
