CPI-613 (Devimistat) in Combination With Modified FOLFIRINOX Plus Bevacizumab in Patients With Metastatic Colorectal Cancer

Phase I Study of the First-In-Class Agent CPI-613 (Devimistat) in Combination With Modified FOLFIRINOX Plus Bevacizumab in Patients With Metastatic Colorectal Cancer

Pre-clinical in vitro and in vivo data as well as early phase 1 clinical trials have shown that both hematologic and solid tumor cells are susceptible to single-agent cytotoxicity by CPI-613 (devimistat), consistent with its selective target of the altered form of mitochondrial energy metabolism in tumor cells, causing changes in mitochondrial enzyme activities and redox status, which lead to apoptosis, necrosis, and autophagy of tumor cells leading to the death of cancer cells. It is our hypothesis that CPI-613 (devimistat) will enhance the efficacy of mFOLFIRINOX plus Bevacizumab when given as a combination treatment. The study will follow a standard 3+3 design. Cohorts of three to six patients will be treated at each dose level until the MTD is defined.

Inclusion Criteria:

1. Written informed consent in accordance with federal, local, and institutional guidelines

2. Patients must have histologically/pathologically confirmed colorectal adenocarcinoma with measurable disease by RECIST 1.1 criteria

3. Patients must have had no prior chemotherapy for metastatic disease with fluoropyrimidine based chemotherapy with oxaliplatin or irinotecan

4. Patients with prior adjuvant chemotherapy are allowed, as long as a minimum of 6 months have passed between the completion of adjuvant therapy and the start of the study medication

5. Age >18 years

6. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1

7. Radiographic evidence of metastatic disease

8. At the time of study entry:

   absolute neutrophil count must be ≥ 1000/mm3, hemoglobin ≥ 9 gm/dL, and platelet count ≥ 100,000/mm3 There must be evidence of adequate hepatic and renal function. Bilirubin must be ≤ 1.5 x upper limit of normal (ULN) for the lab unless the patient has a chronic grade 1 bilirubin elevation due to Gilbert's disease or similar syndrome due to slow conjugation of bilirubin Alkaline phosphatase must be ≤ 3 x ULN for the lab AST and ALT must be ≤ 5 x ULN for the lab Serum creatinine ≤ 1.5 x ULN for the lab Note: For patients with liver metastases, non-fasting bilirubin 1.5 x ULN to 3 x ULN of the institution's normal range are acceptable.

9. Both male and female patients with childbearing potential must agree to use adequatecontraception throughout the study and for 9 months after last dose of mFOLFIRINOX, bevacizumab or CPI-613 (devimistat)

10. Patients without liver metastasis are eligible if they have ALT and AST ≤ 3.0 x ULN

Exclusion Criteria:

1. Diagnosis of anal or small bowel carcinoma

2. Colorectal cancer other than adenocarcinoma, e.g., sarcoma, lymphoma, carcinoid

3. Patients with tumors that are MSI-high/dMMR

4. Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days ofreceiving study therapy

5. Active infection or chronic infection requiring systemic therapy

6. Known history of human immunodeficiency virus (HIV) or acquired immunodeficiencyrelated (AIDS) illnesses with CD4 count < 250 cells/mm3

7. Any of the following cardiac conditions:

   Documented NYHA Class III or IV congestive heart failure, Myocardial infarction within 6 months prior to study entry, Unstable angina within 6 months prior to study entry, Symptomatic arrhythmia

8. Other malignancies unless the patient is considered to be disease-free and has completed therapy for the malignancy ≥ 12 months prior to study entry.

   Patients with the following cancers are eligible if diagnosed and treated within the past 12 months: carcinoma in situ of the cervix, and basal cell and squamous cell carcinoma of the skin

9. Psychiatric or addictive disorders or other conditions that in the opinion of the investigator would preclude the patient from meeting the study requirements or interfere with interpretation of study results

10. Any other chronic or clinically significant medical condition that in the opinion of investigator would jeopardize the safety or rights of the volunteer. Including, but not limited to: diabetes mellitus type I, chronic hepatitis; OR clinically significant forms of drug oralcohol abuse, asthma, autoimmune disease, psychiatric disorders, heart disease, or cancer. Patients must have neuropathy grade 1 or less

11. Pregnancy or lactation at the time of study entry

12. Use of any investigational agent within 4 weeks prior to the first dose study therapy

13. Patients with the following conditions:

    Uncontrolled hypertension (defined as systolic blood pressure ≥ 150 mm Hg and diastolic blood pressure ≥ 100 mm Hg) Bleeding diatheses or hemorrhage within 6 months prior of study enrollment Gastrointestinal perforation or fistulas History of thromboembolic events Reversible Posterior Leukoencephalopathy Syndrome (RPLS), Proteinuria > 1gr/24 hours

14. Patients with current serious, non-healing wound, ulcer and baseline peripheral neuropathy of grade 2 or greater, hypersensitivity reaction to 5-FU, oxaliplatin or other platinum-based drugs, or irinotecan if it was previously administered in the adjuvant setting
