A Phase 2 Trial of High-dose Ascorbate for Pancreatic Cancer (PACMAN 2.1)

A Phase II Trial of Pharmacological Ascorbate, Gemcitabine, and Nab-Paclitaxel for Metastatic Pancreatic Cancer (PACMAN 2.1)

Source: ClinicalTrials.gov · Last updated 23 Jul 2026

Brief summary (registry, in English)

This clinical trial adds high-dose ascorbate (vitamin C) to the standard of care regimen for metastatic pancreatic adenocarcinoma (a type of pancreatic cancer).

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Prior chemotherapy to treat the metastatic disease
  • Other therapy (including radiation) within the past 4 weeks
  • Side effects from prior therapies that are still deemed moderate to severe by a physician
  • Patients actively receiving insulin or who are currently recommended to receive insulin by a doctor
  • Patients who are on the following drugs and cannot have a substitution (or who decline the substitution):
    • warfarin
    • flecainide
    • methadone
    • amphetamines
    • quinidine
    • chlorpropamide

Other illness

  • An active cancer, other than the pancreatic cancer, that requires treatment.
  • Uncontrolled, intercurrent illness
  • HIV positive individuals undergoing therapy due to known drug:drug interaction between antiretroviral drugs and high-dose ascorbate therapy

Lab values

  • Glucose-6-phosphate dehydrogenase (G6PD) deficiency
  • Patients requiring daily finger-stick blood glucose measurements

Other

  • Enrolled in another therapeutic clinical trial
  • Women who are nursing

Who the study is looking for

  • Pathologic diagnosis (cell samples, biopsy, brushing, surgical sample) of adenocarcinoma of the pancreas. Cancer from the Ampullae of Vater is also eligible. The tissue sample can be from a metastatic location, like a lymph node.
  • Metastatic or node positive disease
  • One cancer site, that did not receive radiation therapy, that is at least 1 cm in size when looking at it by CT scan (CAT scan)
  • Recommended to receive gemcitabine and nab-paclitaxel
  • Failed initial therapy or be ineligible for definitive curative therapy (e.g., surgical excision, radiation therapy)
  • A platelet count of at least 100,000 cells per mL
  • A creatinine level of less than 1 1/2 times the upper limit of normal for the local lab test, or, a creatinine clearance of at least 60 mL/(min\*1.73m2)
  • Not pregnant
  • Commit to using birth control during the study (all participants)
