Brief Summary

This phase I/II trial studies the best dose and side effects of glutaminase inhibitor CB-839 and how well it works with panitumumab and irinotecan hydrochloride (phase I only) in treating patients with RAS wildtype colorectal cancer that has spread to other places in the body and does not respond to treatment. Glutaminase inhibitor CB-839 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as panitumumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving glutaminase inhibitor CB-839 with panitumumab and irinotecan hydrochloride may work better in treating patients with colorectal cancer.

Conditions

Colorectal Cancer; Metastatic Colorectal Cancer; RAS Wild Type Colorectal Cancer; Refractory Colorectal Cancer

Outcome Measures

Primary Outcomes (3)

• Maximum Tolerated Dose (Phase I) of CB-839 in Combination With Panitumumab and Irinotecan Hydrochloride

  The maximum tolerated dose of CB-839 will be determined in Phase I with dose-escalation following Bayesian continual reassessment method. Patients were treated in cohort of 3. The CB839 dose leves were 400, 600 and 800mg.

  Up to 12 months

• Response Rate (Phase II)

  The percent of patients with best response as complete response (CR) and partial response(PR) among patients with evaluable result. The response criteria: CR, Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm; PR, At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, Progressive Disease (PD), At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition, the sum must also demonstrate an absolute increase of at least 5 mm. (The appearance of one or more new lesions is also considered progression); Stable Disease(SD), Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.

  Up to 12 months

• Recommended Phase 2 Dose of CB-839 in Combination With Panitumumab and Irinotecan Hydrochloride (Phase I)

  The recommended phase 2 dose will be determined.

  Up to 12 months.

Secondary Outcomes (5)

• Disease Control Rate

  Up to 12 months

• Coefficient of Determination (R2) of Maximum Standardized Uptake Value (SUVmax) of Fluorine F 18 L-glutamate Derivative BAY94-9392 (18F-FSPG) Uptake Change With Tumor Size Change (Phase II)

  Up to 8 weeks

• Plasma Exosomal Content (Phase II)

  Up to 12 months

• Progression Free Survival (Phase II)

  Up to 12 months

• Overall Survival

  Up to 12 months

Study Arms (1)

Panitumumab/Irinotecan/CB-839

EXPERIMENTAL

Patients receive glutaminase inhibitor CB-839 PO BID on days 1-28, panitumumab IV over 60-90 minutes on days 1 and 15, and irinotecan hydrochloride IV over 90 minutes on day 1 and 15 (Phase I only). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Signed and dated written informed consent
• Histologically or cytologically-confirmed diagnosis of metastatic KRAS wildtype colorectal cancer (CRC)
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• In dose escalation, patients must have had at least one prior line of chemotherapy for advanced disease or progressed within 6 months of adjuvant therapy (prior chemotherapy and/or anti-EGFR therapy is permitted)
• In dose expansion, patients must have received prior anti-EGFR therapy and achieved at least stable disease on at least one scan as their best response
• In dose expansion, patients must be willing to undergo a pre-treatment biopsy, and four research PET imaging techniques (11C-Glutamine and 18F-FSPG), two pre-treatment and two after one cycle of treatment
• In dose expansion, at least one measurable lesion as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 which can be followed by CT or magnetic resonance imaging (MRI)
• Absolute neutrophil count (ANC) \>= 1,500/uL
• Platelets \>= 100,000/uL
• Serum albumin \>= 3.0 g/dL
• Serum creatinine =\< 2 mg/dL, or calculated creatinine clearance \> 50 mL/min (per the Cockcroft-Gault formula)
