Brief Summary:
This is a single arm study evaluating the tolerability and markers of colorectal cancer with a specially designed medical food restricted in specific amino acids for the dietary management of subjects with metastatic colorectal cancer. Subjects will be receiving two FDA approved second line drug therapies, fluoropyrimidine and oxaliplatin ± bevacizumab (FOLFIRI + BEV) that are routinely prescribed in combination for metastatic colorectal cancer as part of their routine care.

Arm Intervention/treatment
Experimental: Experimental: Nonessential Amino Acid Restriction (NEAAR) Medical Food
This is a single arm study in which all subjects will receive NEAAR medical food and standard of care FDA approved chemotherapy. Each week NEAAR medical food will be consumed 5 consecutive days followed by 2 days of habitual food.
Other: NEAAR Medical Food
All subjects will receive NEAAR Medical Food, a standardized non-essential amino acid restricted medical food, and will also receive standard of care FDA approved chemotherapy consisting of fluoropyrimidine and oxaliplatin ± bevacizumab (FOLFIRI + BEV).




Primary Outcome Measures :
  1. Demonstrate tolerability of the NEAAR medical food. [ Time Frame: Through study completion, average of 6 months ]
    The primary endpoint is the rate of the most common Grade 3 and 4 adverse event (AE) related to the NEAAR medical food (when added to standard of care chemotherapy) regimen. This will be compared with the rate of the most common Grade 3 and 4 AE of the historical control (i.e. standard of care).


Secondary Outcome Measures :
  1. Comparison of gene mutation and gene expression as predictors of management of disease with the NEAAR medical food, assessed in relation to: [ Time Frame: Through study completion, average of 6 months ]
    Absolute and relative change of biomarkers of interest, CA19-9 and CEA.

  2. Comparison of gene mutation and gene expression as predictors of management of disease with the NEAAR medical food, assessed in relation to: [ Time Frame: Through study completion, average of 6 months ]
    Overall Response Rates using RECIST 1.1

  3. Comparison of gene mutation and gene expression as predictors of management of disease with the NEAAR medical food, assessed in relation to: [ Time Frame: Through study completion, average of 6 months ]
    Progression-free Survival using RECIST 1.1

  4. Comparison of gene mutation and gene expression as predictors of management of disease with the NEAAR medical food, assessed in relation to: [ Time Frame: Through study completion, average of 6 months ]
    Overall survival

  5. Establish the impact of NEAAR medical food on ECOG (Eastern Cooperative Oncology Group) performance status and weight compared to historical controls [ Time Frame: Through study completion, average of 6 months ]
    ECOG Performance Status will be measured utilizing the ECOG performance status scale

  6. Establish all plasma amino acid concentrations (nmol/mL) for the time period the subject is consuming NEAAR medical food and compare with baseline measurements. [ Time Frame: Through study completion, average of 6 months ]
  7. Correlation and regression analysis with blood amino acid concentrations (nmol/mL) for: [ Time Frame: Through study completion, average of 6 months ]
    L-glutamine, L-glutamic acid, L-alanine, glycine, L-arginine, L-proline, L-aspartic acid, L-serine, L-asparagine, L-tyrosine, L-cysteine/L-cystine, L-lysine, L-valine, L-histidine, L-leucine, L-isoleucine, L-tryptophan, L-phenylalanine, L-methionine, L-threonine.

  5. Has failed treatment for fluoropyrimidine and oxaliplatin ± BEV.

    1. All subjects must have received a minimum of 6 weeks of a first line regimen that included oxaliplatin and a fluoropyrimidine ± BEV. Treatment failure is defined as radiologic progression during or < 6 months after the last dose of first-line therapy.
    2. Subjects who show tumor progression while on maintenance therapy with a fluoropyrimidine ± BEV after prior fluoropyrimidine-oxaliplatin ± BEV induction therapy are eligible. Rechallenge with oxaliplatin is permitted and will be considered part of the first-line regimen for metastatic disease, with both initial oxaliplatin treatment and subsequent rechallenge being considered as one regimen.
    3. Subjects who received oxaliplatin/fluoropyrimidine-based neoadjuvant or adjuvant therapy and have disease recurrence or progression > 6 months from their last dose of neoadjuvant or adjuvant treatment (or > 6 months from surgery if no adjuvant therapy was administered) will be required to receive and progress on fluoropyrimidine/oxaliplatin-based therapy ± BEV for metastatic disease.
    4. For subjects with rectal cancer, sequential neoadjuvant and adjuvant therapy will count as a single systemic regimen.
    5. Subjects who discontinued first-line therapy because of toxicity may be enrolled as long as progression occurred < 6 months after the last dose of first-line therapy.
  6. FOLFIRI ± BEV therapy is prescribed for the subject per standard of care.
  7. Females of child-bearing potential (defined as a sexually mature woman who has not undergone hysterectomy or bilateral oophorectomy or has not been naturally postmenopausal for at least 24 consecutive months [i.e., has had menses at any time during the preceding 24 consecutive months]) must:

    1. Commit to true abstinence from heterosexual contact or agree to use, and be able to comply with, effective contraception without interruption until their final study visit and return to habitual food; and
    2. have a negative serum pregnancy test (β -hCG) result at screening. This applies even if the subject practices true abstinence from heterosexual contact.
  8. Male subjects must commit to practicing true abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential starting at screening until discontinuation from study, even if he has undergone a successful vasectomy. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
  9. Subjects with measurable disease as determined by RECIST 1.1.

A minimum of five (ten preferred) formalin fixed paraffin embedded (FFPE) archival or fresh tumor tissue slides are required.
  12. Subjects must be willing to stop taking any supplements, herbal medicines, or alternative remedies or other prescribed or over the counter supplements for at least 1 week prior to Cycle 1 Day 1 of FOLFIRI ± BEV and through the NEAAR medical food period.
