Clinical Trial Summary

This randomized controlled trial is designed to determine the effect of administration of azithromycin compared to amoxicillin as part of the treatment of uncomplicated severe acute malnutrition (SAM) in children aged 6-59 months on weight gain and nutritional recovery. The investigators will randomize children presenting to Taimaka-run nutritional programs at health centers in Gombe State, Nigeria to a single dose of oral azithromycin or a short course of oral amoxicillin upon admission into the program. Apart from the administration of antibiotics, all children will receive standard outpatient treatment for uncomplicated SAM as specified in the guidelines of the government of Nigeria, which includes therapeutic feeding with ready-to-use therapeutic food (RUTF). Enrolled children will be followed weekly at each routine clinic follow-up visit up until nutritional recovery. All enrolled children will return for a final study visit at 8 weeks following enrollment. Anthropometric and vital status data will be collected at each follow-up visit. Weight gain and nutritional recovery over the 8-week study period will be compared by arm as a primary outcome and at 12 weeks as a secondary outcome.

Intervention

Drug:
• Azithromycin
Children enrolled in the trial and randomized to receive azithromycin will receive a single dose of azithromycin at 20 mg/kg up to the maximum adult dose of 1g. Oral azithromycin will be administered at the time of enrollment. Enrolled children will also receive RUTF.
• Amoxicillin
Children enrolled in the trial and randomized to receive amoxicillin will receive a 5-day course of amoxicillin to be given in twice-daily doses of 15 mg/kg per the Nigeria guidelines for severe acute malnutrition. The first dose will be administered at the time of enrollment, and the remaining doses will be administered by the caregiver at home. Enrolled children will also receive RUTF.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Weight Gain over 12 weeks	Weight will be measured at baseline and weekly follow up visits for 8 weeks, and at 12 weeks after admission to the program. Weight gain will be defined as grams per kilogram per day (g/kg/day).	12 weeks
Other	Time to recovery	Time from enrollment to nutritional recovery will be calculated in days by subtracting the date of enrollment from the date of nutritional recovery.	12 weeks
Other	Nonresponse at 8 weeks	Number of children with nonresponse will be documented if a child does not meet the criteria for nutritional recovery at 8 weeks after enrollment.	8 weeks
Other	Transfer to inpatient care	The occurrence, date, and reason for transfer from outpatient to inpatient treatment will be recorded.	12 weeks
Other	Mortality by 8 weeks	Vital status will be assessed at baseline and at weekly follow up visits for 8 weeks, and mortality will be defined as death during the study period. Date of death will be recorded.	8 weeks
Other	Mortality by 12 weeks	Vital status will be assessed at baseline, weekly follow up visits for 8 weeks, and at 12 weeks, and mortality will be defined as death during the study period. Date of death will be recorded.	12 weeks
Other	Clinical signs of infection	Number of participants with clinical sign of infection will be recorded At baseline, weekly follow up visits for 8 weeks, and at the 12-week follow up visit, including care-giver reported experience of fever, diarrhea, vomiting, and respiratory infection/cough and clinical diagnoses made at by site personnel	12 weeks
Other	Height-for-age z-score (HAZ)	Height or length will be measured monthly (baseline and the 4-, 8-, and 12-week follow up visits) and height-for-age z-scores will be calculated.; Anthropomorphic outcomes are defined according to the World Health Organization's 2006 Child Growth Standards; A z-score of 0 represents the population median. The z-score will be positive if the data value lies above the mean, and it will be negative if the value lies below the median. A HAZ < -2 standard distributions below the median is defined as stunted, while a HAZ < -3 standard distributions below the median is defined as severely stunted.	12 weeks
Other	Mid-upper arm circumference (MUAC)	Mid-upper arm circumference (centimeters) will be measured at all follow-up time points (baseline, weekly follow up visits for 8 weeks, and at the 12-week follow up visit).	12 weeks
Other	Weight-for-age z-score (WAZ)	Weight will be measured at all follow-up time points (baseline, weekly follow up visits for 8 weeks, and at the 12-week follow up visit) and weight-for-age z-scores will be calculated.; Anthropomorphic outcomes are defined according to the World Health Organization's 2006 Child Growth Standards; A z-score of 0 represents the population median. The z-score will be positive if the data value lies above the mean, and it will be negative if the value lies below the median. A WAZ < -2 standard distributions below the median is defined as underweight, while a WAZ < -3 standard distributions below the median is defined as severely underweight.	12 weeks
Other	Weight-for-height z-score (WHZ)	Weight and height, assessed at all follow-up time points (baseline, weekly follow up visits for 8 weeks, and at the 12-week follow up visit), will be used to calculate weight-for-height z-scores.; Anthropomorphic outcomes are defined according to the World Health Organization's 2006 Child Growth Standards; A z-score of 0 represents the population median. The z-score will be positive if the data value lies above the mean, and it will be negative if the value lies below the median. A WHZ < -2 standard distributions below the median is defined as moderately wasted, while a WAZ < -3 standard distributions below the median is defined as severely wasted.	12 weeks
Other	Malaria	Rapid diagnostic tests for malaria will be conducted at baseline and week 8 to determine malaria infection status. Positivity rate will be compared between arms	8 weeks
Primary	Weight Gain at 8 weeks	Weight will be measured at baseline and weekly follow ups, and weight gain will be calculated at 8 weeks in g/kg/day	8 weeks
Secondary	Nutritional Recovery at 8 weeks	Nutritional recovery will be defined as a child having WHZ = -2 on two consecutive visits and no acute complication or edema for the past 7 days AND / OR MUAC of = 125mm on 2 consecutive visits and no acute complication or edema for the past 7 days.; Children will be considered recovered or not recovered using these criteria; Anthropomorphic outcomes are defined according to the World Health Organization's 2006 Child Growth Standards; A z-score of 0 represents the population median. The z-score will be positive if the data value lies above the mean, and it will be negative if the value lies below the median. A WHZ < -2 standard distributions below the median is defined as moderately wasted, while a WHZ < -3 standard distributions below the median is defined as severely wasted.	8 weeks
