Funded at University of Oxford · NIH-11258574 · Data updated 2026-11-12

A pediatric study in the US and other settings will check how tafenoquine behaves in the body to prevent relapses of malaria in kids over 28 days old and at least 12 kg.

Who could benefit from this research

Could help

Ideal candidates are children who are ≥28 days old and weigh at least 12 kg who are at risk for P. vivax malaria relapse and can be enrolled in sites with malaria pharmacology expertise.

Less likely to help

Young children under 28 days old or those who cannot take tafenoquine due to health reasons may not benefit.

What this research studies

This project looks at how a single-dose antimalarial medicine moves through and exits a child’s body to prevent liver relapses of Plasmodium vivax malaria. Researchers will analyze pharmacokinetics in children aged from a little over a month to several years, focusing on safe dosing and how age or weight affects drug levels. The study builds on prior pediatric data and aims to optimize a simpler, single-dose regimen for kids who are at risk of relapse. By understanding how tafenoquine works in children, clinicians can improve relapse prevention and keep kids healthier and in school.

Why it matters

Potential benefit: If successful, children at risk of P. vivax relapse could receive a safer, easier-to-dose treatment that reduces hospital visits and improves growth and development.

How similar studies have gone: Previous pediatric pharmacokinetic work suggests feasibility; this study extends knowledge to a broader pediatric age and weight range.
