Brief summary

This pilot clinical trial studies the side effects of ascorbic acid and combination chemotherapy in treating patients with pancreatic cancer that has spread to other places in the body, has come back, or cannot be removed by surgery. Nutrients found in food and dietary supplements, such as ascorbic acid, may improve the tolerability of chemotherapy regimens. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ascorbic acid and combination chemotherapy may work better in treating patients with pancreatic cancer.

Detailed description

PRIMARY OBJECTIVES: I. To determine safety of intravenous ascorbic acid in combination with fluorouracil, irinotecan hydrochloride, leucovorin calcium, and oxaliplatin (FOLFIRINOX) as defined by Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 in patients with advanced pancreatic cancer. SECONDARY OBJECTIVES: I. To test feasibility of collecting quality of life (QOL), patient reported outcomes (PRO) data and correlative studies on patients with advanced pancreatic cancer.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Adverse Events as Determined by CTCAE Version 4.03Up to 28 days after the last treatmentAfter 4 patients are enrolled on the study and receive at least one dose of intravenous ascorbic acid, the data will be reviewed. If 2 out of the 4 cannot complete 2 courses of FOLFIRINOX then the study will be halted.

Secondary

MeasureTime frameDescription
Change in Quality of Life as Defined by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30Baseline to up to 28 days after the last treatmentChange in quality of life over the six measurement times will be modeled using mixed effects linear regression to account for correlation among repeated measurements from the same subjects. Average change in QoL from baseline to follow-up will be computed.

Treatment (FOLFIRINOX, Ascorbic Acid)
Patients receive oxaliplatin IV over 2 hours, irinotecan hydrochloride IV over 90 minutes, leucovorin calcium IV over 2 hours, and fluorouracil IV continuously over 46 hours on day 1. Patients then receive ascorbic acid IV over 2 hours on days 3, 5, 8, 10 and 12. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
