Amgen, Takeda Pharmaceutical, and Millennium, a division of Takeda, announced unfavorable results from the MONET1 pivotal phase III trial evaluating motesanib administered in combination with paclitaxel and carboplatin in 1,090 patients with advanced non-squamous non-small cell lung cancer (NSCLC). The trial did not meet its primary objective of demonstrating an improvement in overall survival.
MONET1 (MOtesanib NSCLC Efficacy and Tolerability Study) is a phase III, multicenter, randomized, placebo-controlled, double-blind trial that enrolled more than 1,000 men and women with NSCLC. Patients were randomized to receive either paclitaxel (200 mg/m2 IV Q3W), carboplatin (target AUC of 6 mg/mL x min IV Q3W), and motesanib (125 mg PO QD) or paclitaxel, carboplatin, and placebo. The primary endpoint of the study was OS, and secondary endpoints included progression-free survival (PFS), objective response rate (ORR), association of placental growth factor with OS, duration of response, and safety and tolerability.
