Abstract
Background: This phase II study estimated the difference in objective response rate (ORR) among patients with advanced nonsquamous non-small-cell lung cancer (NSCLC) receiving paclitaxel-carboplatin (CP) plus motesanib or bevacizumab. Patients and methods: Chemotherapy-naive patients (N = 186) were randomized 1:1:1 to receive CP plus motesanib 125 mg once daily (qd) (arm A), motesanib 75 mg twice daily (b.i.d.) 5 days on/2 days off (arm B), or bevacizumab 15 mg/kg every 3 weeks (q3w) (arm C). The primary end point was ORR (per RECIST). Other end points included progression-free survival (PFS), overall survival (OS), motesanib pharmacokinetics, and adverse events (AEs). Results: ORRs in the three arms were as follows: arm A, 30% (95% confidence interval 18% to 43%); arm B, 23% (13% to 36%); and arm C, 37% (25% to 50%). Median PFS in arm A was 7.7 months, arm B 5.8 months, and arm C 8.3 months; median OS for arm A was 14.0 months, arm B 12.8 months, and arm C 14.0 months. Incidence of AEs was greater in arms A and B than in arm C. More grade 5 AEs not attributable to disease progression occurred in arm B (n = 10) than in arms A (n = 4) and C (n = 4). Motesanib plasma Cmaxand Cminvalues were consistent with its pharmacokinetic properties observed in previous studies. Conclusions: The efficacy of 125 mg qd motesanib or bevacizumab plus CP was estimated to be comparable. Toxicity was higher but manageable in both motesanib arms. Efficacy and tolerability of motesanib 125 mg qd plus CP in advanced nonsquamous NSCLC are being further investigated in a phase III study.
