A Revised Tafenoquine Dose to Improve Radical Cure for Vivax Malaria (TADORE)
February 1, 2024 updated by: Menzies School of Health Research
A Revised Tafenoquine Dose to Improve Radical Cure for Vivax Malaria - TAfenoquine DOsing REvised
The goal of this clinical trial is to assess the efficacy and safety or a revised weight band tafenoquine dose in vivax malaria patients. The main question[s] it aims to answer are:
- is a revised weight-based TQ regimen (TQRevised: target dose 7.5mg/kg) non-inferior to high dose primaquine (7mg/kg over 7 days)
- is a revised weight-based TQ regimen (TQRevised: target dose 7.5mg/kg) superior to fixed dose tafenoquine (300mg)
- is the tolerability and safety of TQRevised acceptable
- is TQRevised acceptable and feasible Participants will receive a tafenoquine target dose 7.5mg/kg in weight bands. Researchers will compare this to patients receiving a fixed dose tafenoquine and high dose primaquine to see if safe and effective.
