Open-Label, Dose-Finding Study Evaluating Safety and PK of FPA144 in Patients With Advanced Solid Tumors

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.
