Abstract

OBJECTIVE:

To evaluate the safety/tolerability and potential antitumor activity of lapatinib, at dose ranges of 1000 to 1500 mg/d, in combination with gemcitabine and gemcitabine/oxaliplatin (GEMOX) in patients with advanced pancreaticobiliary cancer.

MATERIALS AND METHODS:

Patients with advanced pancreaticobiliary cancer were assigned to 1 of 4 cohorts of lapatinib administered once daily. Toxicities, response, and survival were assessed.

RESULTS:

Twenty-five patients were enrolled, 18 with pancreatic cancer and 7 with biliary cancer. Lapatinib, 1500 mg/d, was successfully administered with weekly gemcitabine. Dose limiting toxicities of nausea and anorexia occurred in 2 of 5 patients receiving 1500 mg/d lapatinib with GEMOX. The median survival of all patients was 11 months and the 1-year survival was 48%.

CONCLUSION:

Lapatinib, 1500 mg/d, can be administered with weekly gemcitabine. The maximum tolerated dose of lapatinib is 1000 mg/d with GEMOX. A phase II study of lapatinib and gemcitabine for metastatic pancreatic cancer will be initiated.
