Study Description
Brief Summary:
Urinary schistosomiasis is a debilitating disease in Central Africa and pregnant women are frequently suffering from this condition. Mefloquine is currently investigated as preventive treatment against malaria in pregnancy and mefloquine is also known to exert activity against schistosomiasis. The investigators want to test the hypothesis whether mefloquine may active against urinary schistosomiasis when used as preventive treatment against malaria in pregnancy.

Condition or disease Intervention/treatment Phase
Urinary Schistosomiasis Drug: Mefloquine Drug: S/P Phase 2

Detailed Description:

Objectives

The principal aim of this clinical trial is to evaluate whether mefloquine - when given as intermittent preventive treatment against malaria in pregnancy - shows in vivo activity against concomitant Schistosoma haematobium infection. This study is therefore a "proof of principle" study and is not intended to establish a clinically satisfying cure rate or to formally compare the efficacy of mefloquine with the standard therapy.

Hypothesis

Two underlying hypotheses have been formulated for this proof of principle study.

Primary hypothesis: Mefloquine reduces egg excretion of Schistosoma haematobium by 50% compared to sulfadoxine/pyrimethamine (S/P) treatment when given as IPTp Secondary hypothesis: Mefloquine may lead to an adequate cure rates of Schistosoma haematobium infections compared to S/P (>80%)

Trial Design

The evaluation of mefloquine activity against S. haematobium will be evaluated in the course of an open label multicenter randomized controlled trial assessing the efficacy, tolerability, and safety of mefloquine IPTp against malaria. This study is therefore a nested randomized controlled trial taking advantage of the randomization and treatment allocation procedures of the IPTp trial and assessing the additional efficacy outcome of reduction of S. haematobium egg excretion.

Outcome Measures

Primary Outcome Measures :
  1. Reduction of egg excretion [ Time Frame: 6 weeks after second IPTp ]
    Mefloquine reduces egg excretion of Schistosoma haematobium by 50% compared to sulfadoxine/pyrimethamine (S/P) treatment when given as IPTp


Secondary Outcome Measures :
  1. Cure rate [ Time Frame: 6 weeks after first and second IPTp ]
    Mefloquine may lead to an adequate cure rates of Schistosoma haematobium infections compared to S/P (>80%)
