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

A Phase 1 Open-Label, Dose-Finding Study Evaluating Safety and Pharmacokinetics of FPA144 in Patients With Advanced Solid Tumors

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.

Inclusion Criteria:

• Life expectancy of at least 3 months

• ECOG performance status of 0 to 1

  • Measurable disease as defined by RECIST version 1.1

Exclusion Criteria:

• Untreated or symptomatic central nervous system (CNS) metastases

• Impaired cardiac function or clinically significant cardiac disease

  - Treatment with any anticancer therapy or participation in another therapeutic clinical study with investigational drugs </=14 days (</=28 days for patients in Korea) prior to first dose of FPA144

• Ongoing acute adverse effects from prior anticancer or investigational therapy > NCI CTCAE Grade 1

• Retinal disease or a history of retinal disease or detachment
