Design outcomes

Primary

MeasureTime frame
Proportion of subjects with microfilaria count sustainably reduced by 50% from the baseline value at any time point after the first dose. A sustainable reduction by 50% is defined as a reduction to 50% of baseline LLM for at least four months.

Secondary

MeasureTime frame
1. Proportion of subjects with microfilaria counts reduced sustainably to less than 8100 mf/ml at any time point after first dose by microfilaria count at baseline, by gender 2. Percent reduction in microfilaria counts at each time point quantitated via the range, William geometric mean and median by treatment group, initial microfilaria level and gender 3. Evolution of loa parasitemia with time in each treatment group analysed via General Linear Model
