Prophylaxis of irinotecan-induced diarrhea with neomycin and potential role for UGT1A1*28 genotype screening: A double-blind, randomized, placebo-controlled study. Oncologist, 11, 944–954.doi: 10.1634/theoncologist.11-8-944
Patients were treated with 350 mg/m2 irinotecan during their first cycle of chemotherapy combined with 660 mg neomycin (n = 28; 45%) administered three times daily for three consecutive days starting two days before irinotecan or combined with placebo (n = 34; 55%).
The two groups were balanced for demographic parameters, hematologic function, bilirubin, and liver enzyme values. The administered dose of irinotecan did not differ significantly between groups (mean dose of 640 mg versus 679 mg, p = 0.9).
This was a double-blind, randomized, placebo-controlled study.
