Study type | Interventional |
We will examine whether a combination of Ivermectim (IVM) plus Albendazole (ALB) compared to IVM alone given annually, which is the current standard for mass drug administration (MDA), is more effective in sterilizing adult worms. We will also address whether IVM plus ALB given twice per year is superior to IVM given once per year or twice per year.

---|---|---|---|---|
Primary | parasitologic efficacy | To compare the parasitologic efficacy, as measured by percent fertile adult female worms in nodules at 36 months after administration of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvolus | 36 months | |
Secondary | additional measures of parasitologic efficacy | To compare additional measures of parasitologic efficacy of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus as measured by skin microfilaria levels at additional time points. | 0, 6, 12, 18, 24 and 36 months | |
Secondary | compare the percentage living versus dead female worms | To compare the percentage living versus dead female worms in nodules at 36 months following initiation of therapy of annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus. | 36 months | |
Secondary | compare the number of nodules with intact microfilaria | To compare the number of nodules with intact microfilaria (Mf) at 36 months after administration annual doses of oral ivermectin alone versus ivermectin plus albendazole given annually or biannually in the treatment of subjects infected with Onchocerca volvulus. | 36 months | |
Secondary | assess different treatment regimens on Soil Transmitted Helminth infections | To assess different treatment regimens on Soil Transmitted Helminth (STH) infections based on presence and intensity of ova in stools. | 0, 6, 12, 18, 24 and 36 months | |
Secondary | determine if IVM plus ALB enhances immunological reactions | To determine if IVM plus ALB enhances immunological reactions to adult worms antigens, or release of circulating parasite antigens as potential biomarkers of drug efficacy. | 0, 6, 12, 18, 24 and 36 months | |
Secondary | determine if the host immune response facilitates killing or sterilizing adult worms and microfilariae | To determine if the host immune response facilitates killing or sterilizing adult worms and microfilariae. This can be accomplished by examining immune biomarkers prior to and following treatment using stored whole blood, and serum/plasma samples. | 0, 6, 12, 18, 24 and 36 months |
