Purpose: This phase Ib study evaluated the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of AMG 102, a fully human monoclonal antibody against hepatocyte growth factor/scatter factor (HGF/SF), in combination with bevacizumab or motesanib in patients with advanced solid tumors. Experimental Design: Patients with treatment-refractory advanced solid tumors were sequentially enrolled into four cohorts (3, 10, or 20 mg/kg AMG 102 plus 10 mg/kg bevacizumab i.v. every 2 weeks, or 3 mg/kg AMG 102 i.v. every 2 weeks plus 75 mg motesanib orally once daily). Results: Fourteen patients were enrolled and received AMG 102. The combination of AMG 102 with bevacizumab (n = 12) seemed to have acceptable toxicity. The number of patients (n = 2) who received AMG 102 plus motesanib was insufficient to adequately assess safety. No dose-limiting toxicities were reported. Enrollment in the motesanib cohort was suspended because of reports of cholecystitis in other motesanib studies. Treatment-emergent adverse events among patients receiving AMG 102 plus bevacizumab were generally mild and included fatigue (75%), nausea (58%), constipation (42%), and peripheral edema (42%). No anti-AMG 102 antibodies were detected. Bevacizumab did not seem to affect AMG 102 pharmacokinetics. Circulating total HGF/SF increased from baseline throughout the study. Eight of 10 evaluable patients had reductions in tumor dimensions, and stable disease at = 8, = 16, and = 24 weeks occurred in 9, 7, and 4 patients, respectively. Progression-free survival ranged from 7.9 to 121.9 weeks. Conclusions: AMG 102 in combination with bevacizumab was well tolerated. Further evaluation of AMG 102 in combination with antiangiogenic agents is warranted. Clin Cancer Res; 16(9); 2677-87. (C) 2010 AACR.
