Acronym
COPA
Study hypothesis
H0: No difference between Group 1 (Copa 2x dose), Group 2 (Copa 1x dose) and the control group on variable
H1: At least two of the three treatments differ from each other

Condition
Human immunodeficiency virus (HIV)
Intervention
Group 1 (n = 20): Double dose; supplementation for 12 weeks plus 4 weeks supplement-free follow up
Group 2 (n = 20): Single dose; supplementation for 12 weeks plus 4 weeks
supplement-free follow up
Group 3 (n = 20): Placebo/control; supplementation for 12 weeks plus 4 weeks supplement-free follow up
Dose regimen: 3 times daily x 16 grams = 48 grams of powder per day (for all three arms). Of these 48 grams, the double dose group received 30 grams of NR100063, the single dose group 15 grams of NR100063. The remainder of the product consisted of inert sugars and maltodextrin. The placebo group received 48 grams of maltodextrin. The powder was to be dissolved in water or juice, or mixed with yoghurt.
Duration of study: 16 weeks

Primary outcome measure
The determination of tolerance and safety during the supplementation period. Blood samples drawn at baseline, week 4, week 12 and week 16 and tolerance was assessed at each visit using recall questionnaire.
Secondary outcome measures
To establish the effects of supplementation on biomarkers:
1. HIV immune biomarkers
2. Gut activity assessed by faecal biomarkers
3. Viral load
4. CD4 counts
Blood samples drawn at baseline, week 4, week 12 and week 16 and stool samples were collected at baseline and after 12 weeks.
