Eligibility Criteria
Inclusion
- Subjects with histologically or cytologically confirmed advanced/metastatic or surgically unresectable cholangiocarcinoma, hepatocellular carcinoma, or other solid malignancy with one or more qualifying liver metastases who are refractory to standard therapy
- Have at least one liver tumor or metastasis (≤ 5 cm in size) that is not sub-capsular and not near any major blood vessel
- Have no more than 7 liver lesions
- Is deemed safe for percutaneous intra-tumoral injection by local radiologist
- Measurable disease per RECIST v 1.1 (primary or metastatic disease)
- ECOG performance status or 0 - 1
- Life expectancy of at least 3 months
- Age ≥ 18 years
- Signed, written Institutional Review Board (IRB) approved informed consent
- A negative serum pregnancy test (for nonsterile women of child-bearing potential)
- Baseline Q-T corrected interval (QTc) interval of ≤ 480 msec using Frederica's formula
- Acceptable liver function:
- Bilirubin ≤ 1.5 times upper limit of normal
- AST (SGOT), ALT (SGPT) and Alkaline phosphatase ≤ 5 times upper limit of normal because of cancer or metastases to the liver
- Acceptable renal function, defined as:
- o Serum creatinine ≤ 1.5 ULN or Creatinine Clearance ≥ 30 mL/minute
- Acceptable hematologic status:
- Hemoglobin ≥ 8 g/dL (a transfusion is allowed if Hemoglobin stays stable thereafter)
- Absolute neutrophil count (ANC) ≥ 1,000 cells/mm3
- Platelet count ≥100,000 plt/mm3 x 109/ L (≥ 65,000 if low platelet counts are due to splenic sequestration and portal hypertension)
- Urinalysis with no clinically significant abnormalities
- Acceptable coagulation status with partial thromboplastin time (PTT) and International Normalized Ratio (INR) ≤1.5 times upper limit of normal
- Subject has adequate vitamin D level, as defined by serum total 25-Hydroxyvitamin D \[25(OH)D\] ≥ 20 to \< 60 ng/mL
- Completion of all previous treatments (including surgery, systemic chemotherapy and radiotherapy), as well as supportive care (including transfusion of blood, blood components and granulocyte colony-stimulation factor \[G-CSF\] treatment) at least 3 weeks before screening (6 weeks for nitrosoureas or mitomycin C), with no signs or symptoms of acute toxicity \> Grade 1 (except alopecia)
- For men and women of child-producing potential, the use of effective contraceptive methods during the study
- No aspirin for ≥ 5 days in advance of intra-tumoral administration, as well as discontinuation of antiplatelet and anticoagulant medications for the appropriate amount of time
Exclusion
- New York Heart Association Class III or IV cardiac disease, or myocardial infarction, severe unstable angina, coronary/peripheral artery bypass graft, congestive heart failure within the past 6 months
- Known active, uncontrolled infection with HIV or hepatitis B; patients with hepatitis B allowed if on anti-viral therapy and have a viral load ≤ 500 IU; patients with a history of HIV must be on antiretroviral therapy for at least four weeks and have an HIV viral load ≤ 400 copies/mL, have CD4+ T cell counts ≥ 350 cells/uL and no history of AIDS-defining opportunistic infections within 3 months prior to treatment

- History of variceal bleeding in the last 6 months
- Concomitant medications that are strong inhibitors or inducers of CYP450 enzymes that cannot be stopped or replaced during the study
- Major surgical procedure within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the course of the study. (Note: Placement of a central venous access catheter(s) (e.g., port or similar) is not considered a major surgical procedure.)
- Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
- Pregnant or nursing women. NOTE: Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; or abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
- Participation in a clinical study involving administration of an investigational compound within the past 30 days prior to study entry.
- Previous intratumoral injection within the past 30 days prior to study entry.
- Unwillingness or inability to comply with procedures required in this protocol
- Known allergy or hypersensitivity to the study drug(s) or one of the ingredients in the formulation
- Existence of any surgical, medical or laboratory condition that, in the judgment of the clinical investigator, might interfere with the safety, distribution, metabolism or excretion of the drug
