3. Must have received no more than 3 lines of systemic therapy for metastatic or unresectable disease, consisting of prior treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if RAS wild-type and medically appropriate, an anti-EGFR therapy. Neoadjuvant or adjuvant systemic therapy is not counted as a prior line, and standard of care agents need not be repeated in the metastatic setting if not clinically indicated in the opinion of the investigator

Inclusion criteria for these patients will remain similar to those used during Phase 1.
Key Exclusion Criteria:
Phase 1:
1. Any prior Grade 4 immune-mediated adverse event (imAE) or Grade 3 imAE requiring steroid treatment (\>10 mg/day prednisone or equivalent dose for more than 12 weeks) while receiving immunotherapy that has been documented within the 12 months prior to enrollment.
2. Unresolved toxicity higher than Grade 1 CTCAE v 5 (or higher) attributed to any prior therapy/procedure at screening, except for alopecia.
3. Prior history of serious hypersensitivity reaction to treatment with a monoclonal antibody
4. Patients who are currently pregnant or breastfeeding
5. Use of other investigational drugs (drugs not marketed for any indication) within 14 days or at least 5 half-lives (whichever is shorter) before investigational enrollment (Day 1, Cycle 1 dosing)
6. Patient with history of malignancy (other than the one for which he/she participates in the study or than basal cell carcinoma definitively resected, or other in situ cancers) - unless the patient has undergone curative therapy with no evidence of that disease for 3 years
7. Patients currently receiving cancer therapy (ie, chemotherapy, radiation therapy, immunotherapy, biologic therapy, hormonal therapy, surgery, and/or tumor embolization) or expected to require any other form of antineoplastic therapy while on study.

9. Known CNS metastases (unless clinically stable for at least 4weeks prior to enrollment and off steroids for at least 7 days- exceptions above for physiologic replacement doses of hydrocortisone)
10. Myocardial infarction, symptomatic congestive heart failure (NYHA\> Class II), unstable angina, or serious uncontrolled cardiac arrhythmia within the last 6 months of screening
