GLP-1 RA Plus SOC Treatment in First-line, Metastatic Pancreatic, Colorectal, or Hepatocellular Cancer

Inclusion Criteria:

1\. Histological or cytological diagnosis of pancreatic adenocarcinoma or colorectal adenocarcinoma. Previous tumor tissue testing is acceptable. Please refer to the "additional HCC cohort criteria" below.

2\. The subject has disease that is not amenable to curative-intent management (e.g., oligometastatic disease) 3. Measurable disease per RECIST v1.1 as determined by the investigator 4. Patients must be appropriate candidates for first-line, SOC treatment.

a. SOC treatment as defined by NCCN® guidelines or institutional standard is allowable, however, options restricted to: i. Colorectal: FOLFOX or FOLIFIRI +/- bevacizumab ii. Pancreatic: mFOLFIRINOX iii. HCC: Tremelimumab/Durvalumab b. Patients are eligible who received prior perioperative chemotherapy for curative intent treatment and recurred ≥ 6 months since last dose of chemotherapy.

5\. ≥ 18 years old on day of consent 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 7. Adequate archival frozen or fixed tissue available from primary or metastatic site for genotypic analysis (at least 15 unstained slides and/or tumor block) 8. Adequate hematologic and organ function laboratory values as follows:

a. The ANC ≥ 1500/mm3 without colony stimulating factor support; b. Platelets ≥ 75,000/mm3; c. Hemoglobin ≥ 9 g/dL; d. Bilirubin ≤ 1.5 ´ the ULN. For subjects with known Gilbert's disease, bilirubin ≤ 3.0 mg/dL; e. Serum albumin ≥ 2.8 g/dl; f. ALT and AST ≤ 3.0 ´ ULN; g. Serum creatinine ≤ 1.5 ´ ULN or creatinine clearance (CrCl) ≥ 40 mL/min. For creatinine clearance estimation, the Cockcroft and Gault equation should be used: i. Male: CrCl (mL/min) = (140 - age) × wt (kg) / (serum creatinine × 72); ii. Female: Multiply above result by 0.85; 9. The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document 10. Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (eg, male or female condom) during the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control or practice abstinence during the study and for 4 months after the last dose of study drug(s);

Additional Inclusion Criteria for HCC Cohort ONLY:

11\. Histologically or radiologically confirmed hepatocellular carcinoma (per AASLD/EASL criteria) 12. Unresectable or advanced HCC not amenable to curative surgery or locoregional therapy.

13\. Barcelona Clinic Liver Cancer (BCLC) stage B or C. 14. Child-Pugh Score Class A; or Child-Pugh Class B7 or B8 at discretion of treating physician 15. Patients with HBV infection, characterized by positive hepatitis B surface antigen (HBsAg) and/or hepatitis B core antibodies (anti-HBcAb) with detectable HBV deoxyribonucleic acid (DNA) (≥10 IU/mL or above the limit of detection per local or central lab standard), must be treated with antiviral therapy, as per institutional practice to ensure adequate viral suppression (HBV DNA \<2000 IU/mL) before enrolment. Patients must remain on antiviral therapy for the duration of their participation in the EAP and for 6 months after the last dose of EAP medication. Patients who test positive for anti-hepatitis B core (HBc) with undetectable HBV DNA (\<10 IU/mL or under the limit of detection per local or central lab standard) do not require anti-viral therapy before enrolment. These participants will be tested at every cycle to monitor HBV DNA levels and initiate anti-viral therapy if HBV DNA is detected (≥10 IU/mL or above the limit of detection per local or central lab standard). HBV DNA detectable patients must initiate and remain on anti-viral therapy for time they are on the EAP and for 6 months after the last dose of EAP medication.

Note: Testing required for subjects with a known history otherwise not required.

16\. Patients with HCV infection must have confirmed diagnosis of HCV characterized by the presence of detectable HCV ribonucleic acid (RNA) or anti-HCV antibody upon enrolment (management of this disease is per local institutional practice).
