Study Evaluating the Ketogenic Diet in Patients With Metastatic Pancreatic Cancer

Prior treatment

• Patients must have received no previous radiotherapy, surgery, chemotherapy or investigational therapy for the treatment of their metastatic pancreatic disease. Prior treatment in the adjuvant setting with chemotherapy and radiation are allowed, provided at least 6 months have elapsed since completion of the last therapy and recurrence and no lingering toxicities are present (this will be first line treatment for metastatic disease).
• Major surgery within 4 weeks prior to study entry. (Port-a-cath may be inserted during this time period).

Other illness

• Uncontrolled intercurrent illness, including but not limited to New York Heart Association Class III or IV, myocardial infarction within the past 6 months, or unstable arrhythmia.
• Known infection with HIV, hepatitis B, or hepatitis C.
• Active, uncontrolled bacterial, viral, or fungal infections, requiring systematic therapy.
• Any condition in the opinion of the principal investigator that might interfere with the patient's participation in the study or in the evaluation of the study results.
• Any condition in the opinion of the principal investigator that is unstable and could jeopardize the patient's participation in the study.
• History of Type 1 diabetes.
• History of diabetic ketoacidosis (DKA).

Lab values

• Albumin \< 3.0 g/dL.

Age

• History of other malignancies (except cured basal cell carcinoma, superficial bladder cancer or carcinoma in situ of the cervix) unless documented free of cancer for ≥ 2 years.

Other

• Evidence of central nervous system (CNS) metastasis (negative imaging study, if clinically indicated, within 4 weeks of Screening Visit).
• Unwillingness or inability to comply with procedures required in this protocol, including unwillingness to follow a ketogenic diet.
• Severe malnutrition or body mass index (BMI) \< 18.

• Age ≥ 18 years of age; male or female.
• Histologically or cytologically confirmed metastatic pancreatic ductal adenocarcinoma, not previously treated for their metastatic disease.
• Capable of providing informed consent and complying with trial procedures.
• Karnofsky Performance Status (KPS) of ≥ 70%.
• Life expectancy ≥ 12 weeks.
• Measurable tumor lesions according to RECIST 1.1 criteria.
• \<Grade 2 pre-existing peripheral neuropathy per NCI CTCAE, Version 5.0.
• Patient has acceptable coagulation status as indicated by an INR ≤1.5 times institutional upper limit of normal (ULN). Patients on anticoagulation can be included at the discretion of the investigator.
• Patients must have normal organ and marrow function as defined below:
  • Absolute neutrophil count ≥1,500/mm3
  • Platelet concentration ≥100,000/mm3 with no platelet transfusions within 7 days prior to laboratory sample
  • Hemoglobin ≥ 9.0g/dL (PRBCs may be given to meet this criteria)
  • Hematocrit level ≥ 27%
  • Total bilirubin within 1.25 x ULN
  • AST (SGOT) and ALT (SGPT) ≤ 2.5 times upper limit of normal (if liver metastases are present, then ≤ 5 x ULN is allowed)
  • Serum creatinine \< 1.5 mg/dL.
• Patient must have a Smartphone or computer in order to work with Virta
• Females of child-bearing potential (defined as a sexually mature woman who (1) has not undergone hysterectomy \[the surgical removal of the uterus\] or bilateral oophorectomy \[the surgical removal of both ovaries\] or (2) 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:
  • Either commit to true abstinence\* from heterosexual contact (which must be reviewed on a monthly basis), or agree to use, and be able to comply with, effective contraception without interruption, 28 days prior to starting IP therapy (including dose interruptions), and while on study medication or for a longer period if required by local regulations following the last dose of IP; and
  • Have a negative serum pregnancy test (β -hCG) result at screening and agree to ongoing pregnancy testing during the course of the study, and after the end of study therapy. This applies even if the subject practices true abstinence\* from heterosexual contact.
• Male subjects must practice true abstinence\* or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for 6 months following discontinuation from study treatment, even if he has undergone a successful vasectomy.
  • True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. \[Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception\].
