摘要

Purpose This open-label, phase I, dose-escalation study assessed the maximum-tolerated dose (MTD), safety, pharmacokinetics, and antitumor activity of sunitinib in combination with capecitabine in patients with advanced solid tumors.
Patients and Methods Sunitinib (25, 37.5, or 50 mg) was administered orally once daily on three dosing schedules: 4 weeks on treatment, 2 weeks off treatment (Schedule 4/2); 2 weeks on treatment, 1 week off treatment (Schedule 2/1); and continuous daily dosing (CDD schedule). Capecitabine (825, 1,000, or 1,250 mg/m(2)) was administered orally twice daily on days 1 to 14 every 3 weeks for all patients. Sunitinib and capecitabine doses were escalated in serial patient cohorts.
Results Seventy-three patients were treated. Grade 3 adverse events included abdominal pain, mucosal inflammation, fatigue, neutropenia, and hand-foot syndrome. The MTD for Schedule 4/2 and the CDD schedule was sunitinib 37.5 mg/d plus capecitabine 1,000 mg/m2 twice per day; the MTD for Schedule 2/1 was sunitinib 50 mg/d plus capecitabine 1,000 mg/m2 twice per day. There were no clinically significant pharmacokinetic drug-drug interactions. Nine partial responses were confirmed in patients with pancreatic cancer (n = 3) and breast, thyroid, neuroendocrine, bladder, and colorectal cancer, and cholangiocarcinoma (each n = 1).
Conclusion The combination of sunitinib and capecitabine resulted in an acceptable safety profile in patients with advanced solid tumors. Further evaluation of sunitinib in combination with capecitabine may be undertaken using the MTD for any of the three treatment schedules. J Clin Oncol 28:4513-4520.
