Brief Summary:
This study is designed as a multi-centre randomized, open label trial to compare the safety and efficacy of a high dose primaquine (PQ) treatment in G6PD normal patients with P. falciparum to reduce the risk of subsequent P. vivax episodes to current standard practice of providing only schizontocidal treatment.
Detailed Description:
Plasmodium vivax forms dormant liver stages that reactivate weeks or months following an acute infection. Recurrent infections can be associated with a febrile illness, a 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 primaquine regimen (1.0 mg/kg/day for 7 days) with a 14 day regimen (0.5 mg/kg/day for 14 days). The 7 day PQ regimen was non-inferior to the 14 day regimen and 5-fold more efficacious at reducing P. vivax recurrence than the control.
This study is designed as a multicentre randomized, open label trial to compare the safety and efficacy of a high dose PQ treatment in G6PD normal patients with P. falciparum to reduce the risk of subsequent P. vivax episodes to current standard practice of providing only schizontocidal treatment.
