Malaria Clinical Trial
Official title:
Short Course Radical Cure of P.Vivax in Nepal- a Randomized Controlled Trial
This study is designed as a multicentre randomized, open label trial to assess the safety and efficacy of a low dose short course PQ treatment (3.5mg/kg total dose given over 7 days) in glucose-6-phosphate dehydrogenase (G6PD) normal patients with P.vivax and P falciparum to reduce the risk of subsequent P.vivax episodes.
Plasmodium vivax is associated with recurrent infections weeks or months following the acute infection due to reactivation of dormant liver stages. Recurrent infections can be associated with a febrile illness, cumulative risk of severe anaemia, direct and indirect mortality, and are the most important source of onward transmission of the parasite. In co-endemic areas, there is a very high risk (up to 50%) of patients representing with P.vivax malaria following treatment of P falciparum. Hence, in co-endemic regions there is a strong rationale for eradicating P.vivax hypnozoites from the liver in patients presenting with uncomplicated P. falciparum infections. The recently completed multicentre IMPROV study compared the efficacy of a 7 day PQ regimen (1.0mg/kg/day for 7 days) with a 14 day regimen (0.5mg/kg/day for 14 days). The 7 day PQ regimen was non-inferior to the 14 day regimen and 5 times more efficacious at reducing P.vivax recurrence than the control. This study is designed as a multicentre randomized, open label trial to assess the safety and efficacy of a low dose short course PQ treatment (3.5mg/kg total dose given over 7 days) in G6PD normal patients with P.vivax and P falciparum to reduce the risk of subsequent P.vivax episodes. ;
