Filter by:The purpose of this clinical study is to evaluate safety and immunogenicity in adult healthy volunteers of the vaccine candidate against schistosomiasis named Bilhvax.
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.
Objectives:To reduce the risk of S. haematobium pathology recurrences during the three years following vaccine administration and to control the safety of this therapeutic strategy in children exposed to urinary schistosomiasis. Methodology : Phase III trial, self-contained, randomized, double blind, in two parallel groups receiving 3 injections at D0, W4, W8 and a boost at W52, one group receiving "Bilhvax", the other one placebo, in S. haematobium infected children pretreated by two doses of PZQ (at W9 and W8) Patient included : Infected school children, 6 to 9 years of age. Primary objective : To demonstrate a significant delay of recurrence of the schistosomiasis pathology in vaccine group compared to control group in the 3 years period following the first administration (between D0 and W152). Secondary objective : safety Duration : February 2009 to March 2012
