NCT00449137 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 13

Summary

RATIONALE: Drugs used in chemotherapy, such as fluorouracil and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Arsenic trioxide may help fluorouracil and leucovorin work better by making tumor cells more sensitive to the drugs. Giving arsenic trioxide together with fluorouracil and leucovorin may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of arsenic trioxide and fluorouracil when given together with leucovorin in treating patients with stage IV colorectal cancer that has relapsed or not responded to treatment.

Conditions

Interventions

DRUG

Arsenic trioxide

ATO will be administered at dose levels determined by the dose escalation scheme (section 4.2). Intra-venous (IV) infusion of ATO (mg/kg body weight) over 1-4 hours will be administered for 5 consecutive days (day 1 to day 5) during the first week, twice a week on weeks 2 and 3 (days 8, 11, 15, and 18), and only one day (day 22) of week 4. Treatment will continue for a maximum of 8 cycles, provided that the patient tolerates treatment and there is evidence of clinical benefit.

DRUG

Fluorouracil

Escalate 5-FU, starting at dose 1600 mg/m2. On day 8, 15, and 22 the assigned dose of 5 FU plus 500 mg/m2 of leucovorin will be administered over 24 hours intravenous infusion following the administration of arsenic trioxide. Treatment will continue for a maximum of 8 cycles, provided that the patient tolerates treatment and there is evidence of clinical benefit.

DRUG

Leucovorin calcium

On day 8, 15, and 22 the assigned dose of 5 FU plus 500 mg/m2 of leucovorin will be administered over 24 hours intravenous infusion following the administration of arsenic trioxide. Treatment will continue for a maximum of 8 cycles, provided that the patient tolerates treatment and there is evidence of clinical benefit.

OTHER

Plasma levels of elemental arsenic

Pre-Treatment and and one hour post ATO on days 1, 5, 8, 11,15, 18, and 22

GENETIC

Peripheral Blood Mononuclear Cells (PBMC) for mRNA analysis

Peripheral blood samples (PAXgene Blood RNA tube, Qiagen, USA) will be obtained up to 2 weeks prior to start of treatment (same day as the first FNA) and one hour post ATO on days 1, 5, 8, 11,15, 18, and 22. Along with FNA an additional blood sample will be obtained on day 23 of every odd treatment cycle.

PROCEDURE

Tumor Biopsy (Fine-Needle Aspiration)

Pre-Treatment, Day 23 of Cycles 1, 3, 5, 7
