FIGHT: A Phase 3 Randomized, Double-Blind, Controlled Study Evaluating FPA144 and Modified FOLFOX6 in Patients With Previously Untreated Advanced Gastric and Gastroesophageal Cancer: Phase 3 Preceded by Dose Finding in Phase 1A

This is a multi-center study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of FPA144 in combination with 5-fluorouracil, leucovorin and oxaliplatin (mFOLFOX6) for patients with gastrointestinal malignancies (GI). The phase 1 open label safety run-in will identify a recommended dose of FPA144 to use in the phase 3 portion of the trial.

Phase 1 is an open-label dose-escalation of FPA144 in combination with mFOLFOX6. Eligible patients will have unresectable locally advanced or metastatic GI cancer of any type and be candidates to receive at least 2 doses of mFOLFOX6 chemotherapy. FGFR2 status is not a requirement for enrollment. FGFR2 status will be tested retrospectively by immunohistochemistry (IHC) if tissue is available and a sample will be obtained for circulating tumor deoxynucleic acid (ctDNA) blood assay. Phase 1 consists of at least 2 dosing cohorts of FPA144 in combination with mFOLFOX6 to determine the recommended dose of FPA144 in combination with mFOLFOX6 in the phase 3.

Inclusion Criteria:

         1. Disease that is unresectable, locally advanced, or metastatic (not amendable to curative therapy)

         4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1

         5. Age >/=18 years at the time the ICF is signed

         6. In sexually active patients (women of childbearing potential and males), willingness to use 2 effective methods of contraception, of which 1 must be a physical barrier method (condom, diaphragm, or cervical/vault cap) until 6 months after the last dose of FPA144. Other effective forms of contraception include:

             - Permanent sterilization (hysterectomy and/or bilateral oophorectomy, or bilateral tubal ligation with surgery, or vasectomy) at least 6 months prior to Screening

             - Women of childbearing potential who are on stable oral contraceptive therapy or intrauterine or implant device for at least 90 days prior to the study, or abstain from sexual intercourse as a way of living

         7. Adequate hematological and biological function, confirmed by the following laboratory values within 96 hours prior to enrollment:

             Bone Marrow Function

             - Absolute neutrophil count (ANC) >/= 1.5 × 109/L

             - Platelets >/= 100 × 109/L

             - Hemoglobin >/= 9 g/dL

             Hepatic Function

             - Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 × upper limit of normal (ULN); if liver metastases, then < 5 × ULN

             - Bilirubin < 1.5 × ULN except in patients with Gilbert's disease

             Renal Function

             - Calculated creatinine clearance using cockroft Gault formula >/= 50 mL/min (see Appendix 1)

         8. INR or prothrombin time (PT) < 1.5 x the ULN except for patients receiving anticoagulation, who must be on a stable dose of warfarin for 6 weeks prior to enrollment

         9. Measurable or non-measurable, but evaluable disease using RECIST v1.1

         10. Histologically or cytologically confirmed GI malignancy for which mFOLFOX6 is considered an appropriate treatment (e.g., gastric cancer [GC], colorectal carcinoma, pancreatic adenocarcinoma)

         11. Patient must be a candidate to receive at least 2 doses of mFOLFOX6 chemotherapy

        Exclusion Criteria:

         1. Untreated or symptomatic central nervous system (CNS) metastases (CNS imaging not required). Patients with asymptomatic CNS metastases are eligible provided they have been clinically stable for at least 4 weeks and do not require intervention such as surgery, radiation, or any corticosteroid therapy for management of symptoms related to CNS disease

         2. Impaired cardiac function or clinically significant cardiac disease, including any of the following (Criteria a through g):

             1. Unstable angina pectoris </=6 months prior to enrollment

             2. Acute myocardial infarction </=6 months prior to enrollment

             5. Uncontrolled cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or digoxin

             6. Active coronary artery disease

             7. Fridericiaís corrected QT interval (QTcF) >/= 480

         6. History of interstitial lung disease (e.g., pneumonitis or pulmonary fibrosis)

         7. Evidence or history of bleeding diathesis or coagulopathy

         8. Radiotherapy </= 28 days of enrollment. Patients must be recovered from all acute radiotherapy-related toxicities. No radiopharmaceuticals (strontium, samarium) within 8 weeks of enrollment
