About this study

Official title: Translation of in Vitro and in Vivo Ascorbate Research Into a New Treatment Option for Pancreatic Cancer: Phase I/IIa Clinical Trial

In the United States, approximately 30,000 new cases of pancreatic cancer are diagnosed each year and an almost equal number of deaths are related to this cancer. Different types of chemotherapeutic treatments are used that target different parts of the cancer cell with some success, but there is room for other treatment options.

It is known that people with cancer are using high doses of intravenous vitamin C also known as ascorbate, as a cancer treatment and this is occurring frequently. When Vitamin C is given in this manner, it is not taken by mouth; instead, it enters your body through an IV (intravenous) site, or tube that is inserted through a needle into your vein. If you have a port-a-cath in place, the IV will be given using your port. When Vitamin C enters your body through an IV site, it is known that it acts like a drug and not a vitamin. It produces a substance around the cancer cells called hydrogen peroxide. It has been seen in animal research studies that hydrogen peroxide kills the cancer cells while leaving the normal cells unharmed.

Currently the FDA does not approve the use of high-dose intravenous Vitamin C as a cancer treatment. The use of intravenous Vitamin C in this study is experimental. Furthermore, it is important to know that we do not expect the intravenous Vitamin C given in this study to be healing for the treatment of your cancer.

Read the detailed description

The purpose of this study is to determine if it is safe to give Vitamin C by the vein at high doses to people with pancreatic cancer and if Vitamin C interferes with how well the chemotherapy works on cancer cells. This study will also look at how the body processes of Vitamin C. This study will also help researchers to learn more about long Vitamin C stays in the blood stream, and how rapidly it is used by the body.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intravenous Vitamin CDrug

    Also called IV ascorbic acid

    The first 5 study visits will all take place in the General Clinical Research Center (GCRC). During these visits you will receive IV doses of Vitamin C. The dose of Vitamin C will be started at 25 grams and may be increased up to 125 grams over a two week period. There may be changes in the amount of Vitamin C that you receive based on your blood test levels. The study staff will go over this in more detail with you. The amount of fluid you receive depends on the dose and can be from 2 1/3 cups to 5 cups.

  • GemcitabineDrug

    Also called Gemsar

    Participants receive dexamethasone 10 mg as pretreatment antiemetic; may be given ondansetron, granisetron, or dolasetron, per oncologist. Gemcitibane 1,000mg/m2 IV over 30 minutes Q 21 days. Cycle of treatment: infusions once weekly for 2 consecutive weeks followed by 1 week of rest to continue treatment schedule until they experience disease progression or unacceptable toxicity. CR, PR or SD: treatment will be continued for at least 6 cycles. Discontinuation of therapy may be considered if agreed upon by the participant and oncologist. Dose Modifications: If the patient experiences more than one toxicity, each requiring a dose reduction, follow the guidelines that give the largest dose reduction for the drug. Subsequent doses can be adjusted to as low as 500 mg/m2 for gemcitabine.

Study groupRoleWhat they receive
PK Intravenous Vitamin C and GemcitabineExperimentalWeek 1: 2 visits for escalating doses of intravenous ascorbic acid (IV C). First dose 25 gm followed by 50 gm 2nd visit. Week 2: 3 visits escalating doses of IV C, 75 grams, 100 grams, and 125 grams. Week 3: 2 visits pharmacokinetic evaluation of intravenous ascorbic acid alone at 125 grams; return to the infusion clinic the following morning for a 24 hour blood draw; 2nd visit receive the first infusion of gemcitabine chemotherapy for PK evaluation of gemcitabine alone. Week-4: gemcitabine and IV C co-administered for pharmacokinetics of both drugs to assess for PK variability related to drug-drug interactions. Subjects will return to the infusion clinic the following morning for 24 hour blood draw.
Receives: Drug: Intravenous Vitamin C; Drug: Gemcitabine

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determine safety of combined gemcitabine chemotherapy with IV ascorbate.

    This will be accomplished by enrolling up to 14 participants fitting inclusion criteria into the Phase I portion of the trial: 7 participants will be enrolled at the determined dose levels and if no significant adverse event is identified, then 7 additional participants will be enrolled. Safety will be assessed by obtaining the following evaluations: toxicity graded by the NCI CTCAE v 4.0, urinalysis pre- and post-infusion, ECG, basic metabolic panel, bicarbonate (pH surrogate marker), CBC, and osmolality.

    Measured: 12 months

Secondary outcomes (1)
  1. Assess pharmacokinetic and pharmacodynamic interactions when adding IV AA to front-line gemcitabine chemotherapy in the treatment of locally advanced or metastatic pancreatic cancer not eligible for surgical resection.

    By measuring PK data when combining gemcitabine chemotherapy along with IV ascorbate on the same day, it will be determined if there are reduced gemcitabine levels in the presence of ascorbate. Initially 7 participants will be enrolled and if no significant interaction defined, an additional 7 will be enrolled.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Intravenous Vitamin C and Gemcitabine in people with Pancreatic Cancer, run by Jeanne Drisko, MD, CNS, FACN at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determine safety of combined gemcitabine chemotherapy with IV ascorbate. (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01364805, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jun 2018.
