Combination Therapies for Trichuris Trichiura Infection in Schoolchildren in Honduras

The goal of this Phase III clinical trial is to evaluate the efficacy, safety, and acceptability of different treatment regimens for Trichuris trichiura infection in schoolchildren aged 6 to 15 years living in La Moskitia, Honduras, an area with a high burden of soil-transmitted helminth infections. The main questions it aims to answer are: * Are combination treatments of albendazole and ivermectin more effective than albendazole alone for treating Trichuris trichiura infection? * Does a fixed-dose combination (FDC) of albendazole and ivermectin achieve cure rates comparable to co-administration of the two drugs? * How effective are the different treatment regimens against other soil-transmitted helminths, including Strongyloides stercoralis? * What adverse events occur following treatment with the different regimens? * How acceptable are the different treatment regimens to children and their caregivers? Researchers will compare four treatment groups: placebo, albendazole alone, albendazole plus ivermectin, and a fixed-dose combination of albendazole plus ivermectin. Participants will: * Be randomly assigned to one of the four treatment groups. * Receive a single dose of the assigned treatment. * Provide stool samples before treatment and approximately 21 days after treatment. * Undergo laboratory testing using quantitative real-time PCR (qPCR) to detect and quantify helminth infections. * Be monitored for adverse events after treatment. * Complete acceptability assessments together with their caregivers. The study will provide evidence on the efficacy, safety, and acceptability of a fixed-dose combination of albendazole and ivermectin and its potential use as a simplified treatment strategy for the control of soil-transmitted helminth infections in endemic settings.

Better Options for Lymphatic Filariasis Treatment

The goal of this clinical trial is to learn if mass drug administration with moxidectin in combination with diethylcarbamazine, and albendazole (MoxDA) can treat lymphatic filariasis, scabies and strongyloidiasis in children and adults living in communities where these diseases are common. The main questions it aims to answer are: 1. Does MoxDA clear infection in people with lymphatic filariasis ? 2. Does MoxDA cause any medical problems in infected and uninfected people? Researchers will compare MoxDA with ivermectin given together with diethylcarbamazine and albendazole (IDA) to see if it works better to clear infection and does not cause any more medical problems. Participants will: 1. Be tested to see if they are infected with the parasites that cause lymphatic filariasis, scabies and strongyloidiasis 2. Take 3 single doses of MoxDA or IDA, 12 months apart 3. Visit their village centre once or twice in the 1 week after each treatment for safety checkups
