Abstract Disclosures

Abstract:

Background: The addition of B, an anti-VEGF monoclonal antibody, to chemotherapy has improved outcomes in several solid tumors. Pemetrexed plus B showed promising efficacy in R/M SCCHN (Argiris et al. JCO 2011). E1305 was designed to evaluate the addition of B to a platinum doublet in R/M SCCHN. Methods: B-eligible pts with performance status 0-1, not having received chemotherapy for R/M SCCHN (prior chemotherapy for locally advanced disease allowed ≥ 4 months) and without factors predisposing to bleeding (history of bleeding due to SCCHN, anticoagulation, central cavitary lung metastasis, carotid invasion) were randomized to: A) one of 4 regimens (investigator's choice) given every 3 weeks: A1, cisplatin (C) 100 mg/m2, 5-FU 1000 mg/m2/day x 4 days; A2, carboplatin (Cb) AUC 6, 5-FU 1000 mg/m2/day x 4 days; A3, C 75 mg/m2, docetaxel (D) 75 mg/m2; A4, Cb AUC 6, D 75 mg/m2, or B) the same regimen (B1, B2, B3, B4) plus B 15 mg/Kg IV, every 3 weeks, until progression. Chemotherapy could be stopped after 6 cycles after maximum response. All pts received prophylactic antibiotics. The primary endpoint was overall survival (OS). Control median OS of 8.5 months (mo) was projected; the addition of B was hypothesized to increase median OS to 11.5 mo with a hazard ratio (HR) of 0.74. Results: 403 pts were randomized (200 in arm A; 203 in arm B). Baseline characteristics were well balanced. 38% in arm A/42% in arm B had an oropharyngeal primary; 87% received C or Cb plus D. With a median follow-up of 23.1 mo, median OS was 11 mo in arm A and 12.6 mo in arm B; HR 0.84 (95% CI 0.67-1.05), p = 0.13. The 1-, 2-, 3-, and 4-year OS were 46% vs 51%, 18% vs 26%, 8% vs 16%, 6% vs 13%, in arm A vs B, respectively. Median PFS was 4.4 mo in arm A and 6.1 mo in arm B (HR 0.71, 95% CI 0.58-0.87; p = 0.0012). Objective response rate was 25% in arm A vs 36% in arm B (p = 0.013). Grade 3-5 bleeding occurred in 3.5% in arm A vs 7.7% in arm B (p = 0.08). Conclusions: B added to a standard platinum doublet improved response rate and PFS but not OS in first-line treatment of R/M SCCHN. The control arm in this study performed better than expected.
