• Subject s liver metastases must not be amenable to resection/ablation to No Evidence of Disease (NED) in one stage.
• Subject must be able to tolerate systemic chemotherapy at initiation of study treatment as outlined below (mCRC: FOLFOX or FOLFIRI; ICC: GemOx).

Inclusion Criteria-Metastatic Colorectal Carcinoma

  • hemoglobin > 9 g/dL
  • total bilirubin < 1.5 X institutional upper limit of normal
  • AST(SGOT)/ALT(SGPT) < 2.5 X institutional upper limit of normal OR eGFR within normal as predicted by the CKD-EPI equation > 60 mL/min/1.73 m2.

Inclusion Criteria-Intrahepatic Cholangiocarcinoma

• Subjects must have histologically or cytologically confirmed diagnosis of intrahepatic cholangiocarcinoma confined to the liver (cohort 2), confirmed by the Laboratory of Pathology, NCI. Archival tumor sample may be used but if archival tissue is not available or is not adequate, tissue biopsy will be required
• Clinical or radiographic evidence of metastatic disease to regional (porta hepatis) lymph nodes will be allowed, provided it is amenable to resection.
• Subjects must have radiographically measurable disease
• Disease must be considered unresectable at the time of preoperative evaluation.
• Subjects must have received 1st line systemic chemotherapy
• ECOG performance status <= 1.

• Subjects must have adequate organ and marrow function as defined below:

  • leukocytes >= 2,000/ mm(3)
  • absolute neutrophil count > 1,500/mcL
  • platelets >= 75,000/ mm(3)
  • hemoglobin > 9 g/dL
  • total bilirubin < 1.5 mg/dl
  • creatinine <= 1.5 mg/dl

EXCLUSION CRITERIA:

Exclusion Criteria- All Cohorts

• Subjects who are receiving any other investigational agents.
• Subjects who have previously received rIL-12
• Subjects with active autoimmune diseases, that might deteriorate when receiving an immunostimulatory agent with the exceptions:
• diabetes type I, vitiligo, alopecia, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible;
• subjects requiring hormone replacement with corticosteroids are eligible if the steroids are administered only for the purpose of hormonal replacement and at doses <= 10 mg of prednisone or equivalent per day;
• administration of steroids for other conditions through a route known to result in a minimal systemic exposure (topical, intranasal, intro-ocular, or inhalation) is eligible.
• History of organ transplant, except for transplants that do not require immunosuppression.
• History of or active inflammatory bowel disease (e.g., Crohn s disease, ulcerative colitis).
• Known hypersensitivity or allergic reactions attributed to any compounds of similar chemical or biologic composition to the study medication, such as recombinant IL-12 or other monoclonal antibodies and history of allergic reactions attributed to compounds of similar chemical composition to FUDR or heparin.
• Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke < 6 months prior to enrollment, myocardial infarction < 6 months prior to enrollment, unstable angina, congestive heart failure (>= NYHA III) or serious cardiac arrhythmia requiring medication.
• All conditions associated with significant necrosis of nontumor-bearing tissues.
• Esophageal or gastroduodenal ulcers < 6 months prior to treatment.
• Psychiatric illness/social situations that would limit compliance with study requirements.
• Active concurrent malignancies within the last five years other than colorectal primary except basal cell skin carcinoma and thyroid carcinoma.
• Prior radiation to liver.
• Subjects with active Hepatitis B or C infection.
• Significant acute or chronic infections (i.e., tuberculosis) history of exposure or history of positive tuberculosis test; plus, presence of clinical symptoms, physical or radiographic findings).
• Any condition, including the presence of laboratory abnormalities and/or insufficient normal liver parenchyma, which places the subject at unacceptable risk if they were to participate in the study or confounds the ability to interpret data from the study.

Exclusion Criteria-Metastatic Colorectal Carcinoma

-Subjects with incontrovertible radiographic evidence of disease outside of the colon/rectum (primary) and liver given unlikelihood of benefit from liver-directed therapy.

Note: Lung lesions seen on CT do not always represent metastases. They are very hard to qualify, therefore exception to this exclusion is subjects with fewer than five lung lesions greater than 1 cm that have not increased in size by more than 10% over a 4-month period of time and are amenable to resection should subsequent problematic growth occur. Lesions less than 1 cm are indeterminant as far as etiology is concerned and will be ignored. Subjects with liver metastases and oligometastatic lung lesions (we define oligometastatic as less than 5 amenable to thoracoscopic removal) are still likely to benefit from liver directed therapy.

• Subjects who have undergone extra-hepatic metastasectomy and have a documented disease-free interval less than or equal to 4 months.
• MSI-high subjects who need to be treated with check-point inhibitors.
• Prior treatment with FUDR.

Exclusion Criteria-Intrahepatic Cholangiocarcinoma

• Presence of distant metastatic disease. Clinical or radiographic evidence of metastatic disease to regional lymph nodes will be allowed, provided it is amenable to resection.
• Prior treatment with FUDR.
• Diagnosis of sclerosing cholangitis.
• Clinical evidence or portal hypertension (ascites, gastroesophageal varices, or portal vein thrombosis).
