Development of a new primaquine radical cure regimen
Primaquine is widely recommended but often not used. We have shown, using a new approach combining genotyping and time to event modelling, that if primaquine is used properly it can prevent nearly all relapses. This currently requires testing for G6PD deficiency and this is relatively expensive and generally unavailable. We have modelled an ascending dose regimen that should avoid dangerous haemolytic toxicity and could therefore be used without G6PD testing. This regimen is being tested in an adaptive trial design in known G6PD deficient healthy volunteers.
