Clinical Trial Summary

An open label, randomized controlled trial of single vs. multiple treatments of praziquantel in intestinal African schistosomiasis in Côte d'Ivoire This study aims to determine the efficacy of repeated (up to four times) praziquantel treatment against S. mansoni infection in school-age children from Côte d'Ivoire using the traditional Kato-Katz thick smear technique, but also with more accurate and non-invasive antigen- and DNA-detection methods.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cure rate	The difference in cure rate (percentage negative) between intervention and control arm by Kato-Katz technique	8 weeks
Secondary	Reduction rates	The difference in egg reduction rate (by Kato-Katz), cure rate and circulating anodic and cathodic antigen and DNA reduction rate after multiple doses of praziquantel (40 mg/kg) by Kato Katz (KK), point-of-care circulating cathodic antigen assay (POC-CCA), up-converting phosphor lateral flow circulating anodic antigen assay (UCP-LF-CAA) and polymerase chain reaction (PCR), respectively.	8 weeks
Secondary	Sensitivity and specificity	Sensitivity and specificity of Kato Katz (KK), point-of-care circulating cathodic antigen assay (POC-CCA), up-converting phosphor lateral flow circulating anodic antigen assay (UCP-LF-CAA) and polymerase chain reaction (PCR) at different time points.	8 weeks
