Dose escalation of FPA144 (0.3 mg/kg to 15 mg/kg)

Dose escalation of FPA144 (3-10 mg/kg) in patients with gastric cancer

Evaluation of objective responses in patients with tumors with various levels of FGFR2b overexpression

FPA144 will be administered by IV infusion over approximately 30 minutes every 2 weeks.

FPA144

Medical Lead

This is a three-part, open-label, safety, tolerability, and PK study of FPA144. Patients will be enrolled in Part 1 (A or B, dose escalation) or Part 2 (dose expansion) of the study, but not both.

Part 1A is a dose-escalation study in patients with any locally advanced or metastatic solid tumor or lymphoma for which standard therapies have been exhausted. Part 1B will further assess safety and evaluate PK of FPA144 in gastric cancer patients.

Part 2 patients will be enrolled and treated in order to further characterize safety and preliminary efficacy in a selected cancer patient population with the greatest potential for clinical benefit from FPA144 treatment.

Region of Enrollment
