Study to Test the Safety and Tolerability of PF-07062119 in Patients With Selected Advanced or Metastatic Gastrointestinal Tumors.

A PHASE 1 DOSE ESCALATION AND EXPANSION STUDY EVALUATING THE SAFETY, TOLERABILITY, PHARMACOKINETICS, PHARMACODYNAMICS AND ANTI TUMOR ACTIVITY OF PF-07062119 IN PATIENTS WITH ADVANCED GASTROINTESTINAL TUMORS

A phase 1, open-label, dose escalation and expansion study of PF-07062119 in patients with selected advanced or metastatic gastrointestinal tumors

This is a Phase 1, open-label, multi-center, non-randomized, multiple dose, safety, tolerability, pharmacokinetic, and pharmacodynamic study of PF-07062119 administered as a single agent in sequential dose levels and then in combination with anti-programmed cell death -1 protein (anti-PD-1) and in combination with an anti-vascular endothelial growth factor (anti-VEGF). In Part 1A, successive cohorts of patients will receive escalating doses of PF-007062119 and then in dose finding (Part 1B) with PF-07062119 in combination with anti-PD-1 and in combination with anti-VEGF. This study contains 2 parts, dose escalation with single agent (Part 1A) and then dose finding with PF-007062119 in combination with ant-PD-1 and in combination with anti-VEGF (Part 1B) followed by dose expansion arms as a single agent and PF-07062119 in combination with anti-PD 1 and in combination with anti-VEGF (Part 2).

Inclusion Criteria:

• For Part 1 and Part 2, diagnosis of advanced/metastatic colorectal, gastric or esophageal adenocarcinoma that is resistant to standard therapy or for which no local regulatory approved standard therapy is available that would confer significant benefit.
• For Part 2, diagnosis of colorectal adenocarcinoma that is resistant to standard therapy or for which no standard therapy is available
• Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0 or 1
• Measurable disease or non-measurable disease and refractory to or intolerant of existing therapies (Part 1)
• Measurable disease as defined by RECIST 1.1 is required (Part 2)

Exclusion Criteria:

• Known active uncontrolled or symptomatic Central Nervous System (CNS) metastases
• Other active malignancy within 3 years prior to randomization, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ

• Last anti-cancer treatment within 4 weeks prior to study entry
• Active or history of clinically significant autoimmune disease that required systemic immunosuppressive medication
• Active or history of clinically significant gastrointestinal disease
• Participation in other studies involving investigational drug(s) within 2 weeks prior to study entry
• Pregnant or breastfeeding female patients
