Registration Number

Brief Summary

RATIONALE: Calcium aluminosilicate anti-diarrheal (CASAD) may help treat and prevent diarrhea caused by irinotecan. It is not yet known whether CASAD is more effective than a placebo in treating and preventing diarrhea in patients receiving irinotecan.

PURPOSE: This randomized phase II trial is studying CASAD to see how well it works compared with a placebo in treating and preventing diarrhea in patients with metastatic colorectal cancer receiving irinotecan.

Detailed Description

OBJECTIVES:

Primary

* To compare the efficacy of calcium aluminosilicate anti-diarrheal (CASAD) versus placebo in reducing the incidence of grade 3 or 4 diarrhea in patients with metastatic colorectal cancer receiving an irinotecan-based chemotherapy regimen.

Secondary

* To compare stools per day in patients treated with these drugs.

* To compare chemotherapy dose reductions and delays due to diarrhea in patients treated with these drugs.

* To compare quality of life of patients treated with these drugs.

* To compare the safety of these drugs in these patients.

* To compare the incidence of grade 3 or 4 diarrhea in patients treated with these drugs.

OUTLINE: This is a multicenter study. Patients are stratified according to chemotherapy regimen (irinotecan hydrochloride in combination with fluorouracil and/or biologic therapy vs irinotecan hydrochloride alone). Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive oral calcium aluminosilicate anti-diarrheal (CASAD) 4 times daily for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients who develop grade 3 or 4 diarrhea and are removed from the study may receive CASAD for an additional 6 weeks.

* Arm II: Patients receive oral placebo 4 times daily for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients who develop grade 3 or 4 diarrhea and are removed from the study may then receive CASAD for 6 weeks.

Patients undergo quality-of-life assessment at baseline and at weeks 3, 5, and 6.

After completion of study treatment, patients are followed for 30 days.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Grade 3/4 DiarrheaFirst 6 weeks from baseline in initial intervention with CASAD or PLACEBO

One hundred patients were randomized equally between CASAD and placebo arms in order to assess whether CASAD was efficacious in preventing grade 3/4 diarrhea within 6 weeks for each arm compared. Bayesian futility monitoring in the study with a recommendation to stop the trial for futility if it became clear that CASAD was not better than placebo.
