Silymarin (Milk Thistle Extract) in Treating Patients With Acute Lymphoblastic Leukemia Who Are Receiving Chemotherapy
RATIONALE: Silymarin (milk thistle extract) is an herb that may be effective in treating liver disorders caused by cancer therapy.
PURPOSE: Randomized phase II trial to study the effectiveness of silymarin in treating patients who have acute lymphoblastic leukemia with chemotherapy-related side effects to the liver.
Drug/Agent Toxicity by Tissue/Organ
Dietary Supplement: silymarin
|Study Design:||Allocation: Randomized
Primary Purpose: Supportive Care
|Official Title:||A Pilot Study of Silymarin During Maintenance Therapy in Children With Acute Lymphoblastic Leukemia (ALL)|
- Effect of silymarin on elevated liver function tests (AST, ALT, total bilirubin, and direct bilirubin) at baseline, day 28, and day 56
- Serum antioxidant capacity as measured by the Oxygen Radical Absorbance Capacity (ORAC) at baseline, day 28, and day 56
- Oxidative damage as measured by 8-oxodeoxyguanosine adducts at baseline, day 28, and day 56
|Study Start Date:||November 2001|
|Study Completion Date:||January 2010|
- Determine the effect of silymarin, in terms of liver function tests, in patients with acute lymphoblastic leukemia receiving hepatotoxic chemotherapy.
- Determine the effect of this drug on free and conjugated serum silibinin values in these patients.
- Determine the serum antioxidant capacity by Oxygen Radical Absorbance Capacity in patients treated with this drug.
- Determine the oxidative damage, as determined by 8-oxodeoxyguanosine adducts, in patients treated with this drug.
OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive oral silymarin daily for 28 days.
- Arm II: Patients receive oral placebo as in arm I. Patients are followed at day 56.
PROJECTED ACCRUAL: A total of 50 patients (25 per treatment arm) will be accrued for this study.
