Purpose

This is an open-label Phase 2 Pilot study to evaluate Disulfiram+Copper Gluconate in patients metastatic pancreatic cancer whose CA-19-9 levels rise while receiving nab-paclitaxel (Abraxane) plus gemcitabine (Gemzar) or FOLFIRINOX or single-agent gemcitabine (Gemzar). Patient must have received a minimum of 8 weeks of treatment and have rising CA-19-9 levels in the absence of radiographic evidence of progression.

Detailed Description

      This study has 3 arms with 5 patients enrolled in each of the three arms. The three treatment
      arms are based upon whether the patient has previously received Abraxane-Gemcitabine or
      FOLFIRINOX or single-agent Gemcitabine without radiographic evidence of disease progression
      for a minimum of 8 weeks , based on the investigator's opinion, but with a rising CA 19-9
      levels. Rising CA 19-9 is defined as an increased over baseline of > 20% in two consecutive
      time points within 8 days of each other. Study sites will provide all chemotherapy for
      patients participating in the study as a "standard of care". DSF/Cu will be provided by the
      Sponsor and shipped from the Sponsor's central depot to the study sites. Sufficient amounts
      of DSF/Cu will be available at the study site prior to enrolling patients in the study.

Eligibility Criteria

        Inclusion Criteria:

          1. 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.

          2. Patient should currently be receiving a chemotherapy regimen comprising FOLFIRINOX or
             Abraxane-Gemcitabine or single-agent Gemcitabine as front-line treatment for

             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.
