Background: The purpose of this study was to evaluate the safety and efficacy of nimotuzumab in combination with chemotherapy (docetaxel and carboplatin) versus chemotherapy alone in patients with stage IIIB/IV non-small-cell lung cancer.
Methods: This multicenter, open-label, Phase II study randomized 110 patients to receive nimotuzumab plus chemotherapy (nimotuzumab group) or chemotherapy alone (control group), and comprised concomitant, maintenance, and follow-up phases. Nimotuzumab 200 mg was administered once weekly for 13 weeks during the first two phases with four cycles of chemotherapy and docetaxel 75 mg/m2 and carboplatin (area under the curve 5 mg/mL*min) every 3 weeks for a maximum of four cycles during the concomitant phase. The primary endpoint was objective response rate (sum of complete response and partial response). Secondary endpoints, ie, overall survival and progression-free survival, were estimated using the Kaplan–Meier method. Efficacy was evaluated on the intent-to-treat and efficacy-evaluable sets. Safety was assessed from adverse event and serious adverse event data.
Results: The objective response rate was significantly higher in the nimotuzumab group than in the control group in the intent-to-treat population (54% versus 34.5%; P=0.04). A complete response and partial response were achieved in 3.6% and 50% of patients, respectively, in the nimotuzumab group, and in 4% and 30.9% of patients, respectively, in the control group. No significant differences in median progression-free survival and overall survival were observed. Safety profiles were comparable between the two groups.
Conclusion: Nimotuzumab plus chemotherapy significantly improved the objective response rate as compared with chemotherapy alone. The combination was safe and well tolerated in patients with stage IIIB/IV non-small-cell lung cancer.
