N-Acetylcysteine vs Placebo as Adjunctive Treatment in Pediatric Leukemia: A Single Blind, Randomized Controlled Trial

The current study has been designed as a randomized single-blind placebo-controlled clinical trial. Sample size calculation for the study was 18 newly diagnosed ALL children in each group using the numerical unpaired two groups data analysis formula. Subjects were recruited from newly diagnosed children with ALL and will start the induction phase of chemotherapy both in hospital ward and outpatient clinic in the Child Health Department at Cipto Mangunkusumo Hospital from August to December 2020. Subjects' parents received an explanation about the study, including the objective and benefits of the study, and also the procedure which will be held. Parents were then asked about the willingness to join the study and signed the form.

Subjects were randomized consecutively and distributed into two groups. Randomization was done by a third person to decide the distribution of the subjects based on the serial number of randomization. Subjects in treatment group will be given capsules containing 600 mg of NAC and subjects in the control group will be given capsules containing placebo (lactose) as the adjunctive treatment during the 6 week induction phase of chemotherapy. Both of the medicines were prepared by the Installation of Pharmacy in Cipto Mangunkusumo National Hospital with the same type and same color of capsules. NAC will be administered during the induction phase of chemotherapy starting in the first week until 6 weeks. This study will analyze change of MDA levels, transaminase enzyme levels, and bilirubin levels before and after the 6th week of the induction phase of chemotherapy.
