ABSTRACT: PURPOSE To evaluate the efficacy of cetuximab plus taxane/carboplatin (TC) as first-line treatment of advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS This multicenter, open-label, phase III study enrolled 676 chemotherapy-naïve patients with stage IIIB (pleural effusion) or IV NSCLC, without restrictions by histology or epidermal growth factor receptor expression. Patients were randomly assigned to cetuximab/TC or TC. TC consisted of paclitaxel (225 mg/m(2)) or docetaxel (75 mg/m(2)), at the investigator's discretion, and carboplatin (area under the curve = 6) on day 1 every 3 weeks for < or = six cycles; cetuximab (400 mg/m(2) on day 1, 250 mg/m(2) weekly) was administered until progression or unacceptable toxicity. The primary end point was progression-free survival assessed by independent radiologic review committee (PFS-IRRC); overall response rate (ORR), overall survival (OS), quality of life (QoL), and safety were key secondary end points. PFS and ORR assessed by investigators were also evaluated. Results Median PFS-IRRC was 4.40 months with cetuximab/TC versus 4.24 months with TC (hazard ratio [HR] = 0.902; 95% CI, 0.761 to 1.069; P = .236). Median OS was 9.69 months with cetuximab/TC versus 8.38 months with TC (HR = 0.890; 95% CI, 0.754 to 1.051; P = .169). ORR-IRRC was 25.7% with cetuximab/TC versus 17.2% with TC (P = .007). The safety profile of this combination was manageable and consistent with its individual components. CONCLUSION The addition of cetuximab to TC did not significantly improve the primary end point, PFS-IRRC. There was significant improvement in ORR by IRRC. The difference in OS favored cetuximab but did not reach statistical significance.

ABSTRACT: Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, increases survival when combined with irinotecan-based chemotherapy in first-line treatment of metastatic colorectal cancer (CRC). This randomized, phase II trial compared bevacizumab plus fluorouracil and leucovorin (FU/LV) versus placebo plus FU/LV as first-line therapy in patients considered nonoptimal candidates for first-line irinotecan.
Patients had metastatic CRC and one of the following characteristics: age > or = 65 years, Eastern Cooperative Oncology Group performance status 1 or 2, serum albumin < or = 3.5 g/dL, or prior abdominal/pelvic radiotherapy. Patients were randomly assigned to FU/LV/placebo (n = 105) or FU/LV/bevacizumab (n = 104). The primary end point was overall survival. Secondary end points were progression-free survival, response rate, response duration, and quality of life. Safety was also assessed.
Median survival was 16.6 months for the FU/LV/bevacizumab group and 12.9 months for the FU/LV/placebo group (hazard ratio, 0.79; P = .16). Median progression-free survival was 9.2 months (FU/LV/bevacizumab) and 5.5 months (FU/LV/placebo); hazard ratio was 0.50; P = .0002. Response rates were 26.0% (FU/LV/bevacizumab) and 15.2% (FU/LV/placebo) (P = .055); duration of response was 9.2 months (FU/LV/bevacizumab) and 6.8 months (FU/LV/placebo); hazard ratio was 0.42; P = .088. Grade 3 hypertension was more common with bevacizumab treatment (16% v 3%) but was controlled with oral medication and did not cause study drug discontinuation.
Addition of bevacizumab to FU/LV as first-line therapy in CRC patients who were not considered optimal candidates for first-line irinotecan treatment provided clinically significant patient benefit, including statistically significant improvement in progression-free survival.
