Volunteers: No Healthy Volunteers

Inclusion criteria

1. Signed written informed consent

2. A histologically confirmed solid tumor of the gastrointestinal tract including

   1. Advanced unresectable, metastatic or recurrent colorectal carcinoma (CRC) for which treatment with FOLFOX6 with or without bevacizumab, FOLFIRI with or without bevacizumab, CAPOX, or regorafenib would be acceptable as determined by the Investigator. FOLFIRI/XELIRI-refractory patients with CRC enrolling on the FOLFIRI study arm must have failed treatment with one FOLFIRI pr XELIRI with or without bevacizumab regimen for unresectable or metastatic disease. Treatment failure is defined as progression of disease (clinical or radiologic) during treatment with FOLFIRI with or without bevacizumab or < 3 months after the last dose of treatment with FOLFIRI with or without bevacizumab. Patients with CRC enrolling on the regorafenib arm of this study will have previously received at least two previous lines of therapy for advanced colorectal cancer, and will have previously received treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. Patients with K-ras wild type tumors enrolling on the regorafenib arm will also have previously received either cetuximab or panitumumab.
   2. Hepatocellular carcinoma for which treatment with FOLFOX6 or CAPOX would be acceptable as determined by the Investigator.
   3. Pancreatic adenocarcinoma for which treatment with FOLFOX6, CAPOX, FOLFIRI, or irinotecan would be acceptable as determined by the Investigator.
   4. Cholangiocarcinoma for which treatment with FOLFOX6 or CAPOX would be acceptable as determined by the Investigator.
   5. Gastric, GEJ or esophageal adenocarcinoma for which treatment with FOLFOX6, CAPOX, FOLFIRI, or irinotecan would be acceptable as determined by the Investigator.

3. Patients may be treatment naïve, or may have received standard chemotherapy; including regimens containing a fluoropyrimidine, or oxaliplatin, or irinotecan, or regorafenib, or bevacizumab.

4. ≥18 years of age.

5. Karnofsky performance status score ≥70%.

6. Male or female patients of child-producing potential agree to use contraception or avoidance of pregnancy measures during the study and for 30 days after the last BBI608 dose.

8. AST level ≤2.5 x ULN and ALT ≤ 2.5 × ULN. For patients with liver metastases, AST ≤3.5 x ULN, and AST ≤3.5 x ULN may be enrolled if agreed upon by the investigator and medical monitor for the sponsor.

9. Hemoglobin ≥10 g/dl.

10. Total bilirubin level ≤1.5 × ULN.

11. Creatinine ≤1.5 x ULN or creatinine clearance >60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal (as determined by Cockcroft-Gault equation).

12. Absolute neutrophil count ≥ 1.5 x 10^9/L.

13. Platelets ≥100 x 10^9/L.

14. Life expectancy estimated at ≥3 months.
