Disulfiram-Copper Gluconate in Met Pancreas Cancer w Rising CA19-9 on Abraxane-Gemzar, FOLFIRINOX or Gemcitabine
Metastatic Pancreatic Cancer
About this trial
This is an interventional treatment trial for Metastatic Pancreatic Cancer
Eligibility Criteria
Inclusion Criteria:
- Patients must have histologically confirmed adenocarcinoma of the pancreas that is metastatic and for which potential curative measures, such as resection of an isolated metastasis, are not available. Patients with islet cell neoplasms are excluded.
- Patient should currently be receiving a chemotherapy regimen comprising FOLFIRINOX or Abraxane-Gemcitabine or single-agent Gemcitabine as front-line treatment for metastatic disease. Patients who have had chemotherapy in the adjuvant or neoadjuvant setting are eligible.
- Patients must have previously received a minimum of 8 weeks of therapy with Abraxane-Gemcitabine or FOLFIRINOX or single-agent Gemcitabine without radiographic evidence of disease progression based on the investigator's opinion, but a rising CA 19-9 level, and still be undergoing treatment with Abraxane-Gemcitabine or FOLFIRINOX or single-agent Gemcitabine. Increased CA 19-9 is defined as an increased over baseline of > 20% in two consecutive time points within 8 days of each other.
- Patient has one or more metastatic tumors measurable by CT scan. Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional techniques or as >10 mm with spiral CT scan.
- Male or non-pregnant and non-lactating female and ≥ 18 to ≤ 80 years of age.
- Patient has adequate biological parameters as demonstrated by the following blood counts at Screening (obtained ≤ 14 days prior to enrollment) and at Baseline-Day 0: Absolute neutrophil count (ANC) ≥ 1.5 × 109/L; Platelet count ≥ 100,000/mm3 (100 × 109/L); Hemoglobin (Hgb) ≥ 9 g/dL.
Patient has the following blood chemistry levels at Screening (obtained ≤ 14 days prior to enrollment) and at Baseline-Day 0:
- AST (SGOT), ALT (SGPT) ≤ 2.5 × upper limit of normal range (ULN), unless liver metastases are present, then ≤ 5 × ULN is allowed. Total bilirubin ≤ 1.5 × ULN.
- Serum creatinine < 1.5X ULN or estimated creatinine clearance of > 60 mL/min (per Cockroft-Gault formula)
- Patient has ECOG performance status from 0 to ≤ 1.
- Patient has been informed about the nature of the study, and has agreed to participate in the study, and signed the Informed Consent Form (ICF) prior to participation in any study-related activities.
Exclusion Criteria:
- Patient has brain metastases.
- Patient has experienced an increase of ECOG to > 1 between Screening and enrollment.
- QTc > 480 msec if patient receiving oxaliplatin-containing regimen.
- Patient has active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy.
- Patient has a history of allergy or hypersensitivity to any of the study drugs, their pharmaceutical class or any of their excipients. The patient exhibits any of the events outlined in the Contraindications or Special Warnings and Precautions sections of Gemcitabine or Abraxane ® Prescribing Information package inserts or on the Investigator's Brochure for DSF/Cu.
- Patient has a concomitant serious medical or psychiatric illness that, in the opinion of the investigator, could compromise the patient's safety or the study data integrity.
- Patient is enrolled in any other clinical protocol or investigational trial involving administration of antineoplastic compounds for the treatment of metastatic pancreatic cancer.
- Patient is unwilling or unable to comply with study procedures.
- Abraxane is metabolized by CYP2C8 and CYP3A4. Co-administration of substrates, inhibitors of CYP2C8 (see Appendix C) and/or CYP3A4 (see Appendix D) with Abraxane is not allowed. The following medications and substances are not allowed during the study: ritonavir, saquinavir, indinavir, nelfinavir, rifampicin, carbamazepine, phenytoin, efiravenz, or nerivapine, grapefruit (juice or seeds) or some herbals like St. John's wort.

Subjects with metastatic adenocarcinoma of the pancreas who have received a minimum of 8 weeks of treatment with Nab-Paclitaxel-Gemcitabine with rising CA 19-9 levels in the absence of radiographic evidence of progression will continue to receive treatment with addition of Disulfiram+Copper Gluconate until disease progression.
Subjects with metastatic adenocarcinoma of the pancreas who have received a minimum of 8 weeks of treatment with FOLFIRINOX and with rising CA 19-9 levels in the absence of radiographic evidence of progression will continue to receive treatment with addition of Disulfiram+Copper Gluconate until disease progression.
Subjects with metastatic adenocarcinoma of the pancreas who have received a minimum of 8 weeks of treatment with Single-Agent Gemcitabine and with rising CA 19-9 levels in the absence of radiographic evidence of progression will continue to receive treatment with addition of Disulfiram+Copper Gluconate until disease progression.
