PURPOSE: Axitinib (AG-013736), an oral, potent, and selective inhibitor of vascular endothelial growth factor (VEGF) receptors 1, 2, and 3, is under investigation for treatment of various solid tumors. The safety and pharmacokinetics of axitinib in combination with gemcitabine in patients with advanced pancreatic cancer was evaluated in the phase I portion of this trial. The randomized phase II portion was reported separately.
PATIENTS AND METHODS: Patients with advanced pancreatic cancer who had received no prior chemotherapy were eligible for this study. Pharmacokinetic profiles of the drugs were obtained on cycle (C) 1 day (D) 1 (gemcitabine alone 1,000 mg/m(2)), C1D14 (steady state, axitinib alone 5 mg twice daily [BID]), and C1D15 (gemcitabine plus steady-state axitinib). Adverse events were monitored weekly at the clinic.
RESULTS: Eight patients participated in the phase IB portion of the trial. Patients received gemcitabine on D1, D8, and D15 and continuous axitinib in a 28 day-cycle beginning C1D3. There was no dose-limiting toxicity. Common treatment-related adverse events included fatigue, diarrhea, dysphonia, and hypertension. Myelosuppression was similar to gemcitabine monotherapy. No apparent major pharmacokinetic interactions between gemcitabine and axitinib were observed. Of six patients evaluable for efficacy, three had confirmed partial responses.
CONCLUSIONS: Axitinib (5 mg BID) and gemcitabine (1,000 mg/m(2)) were well tolerated when administered together, without any pharmacokinetic interactions, and showed encouraging antitumor activity.
