What this research studies

You would be part of a study testing a personalized dosing approach that measures how hydroxyurea behaves in each child and then sets an individualized daily dose. Children at two clinical sites (Luanda, Angola and Mwanza, Tanzania) are randomly assigned to receive this precision dosing approach or standard dosing. The team uses a portable, battery-powered HPLC device to measure drug levels and aims to limit frequent lab visits and reduce blood-related toxicities. The goal is to make hydroxyurea treatment more practical and safer for children in low-resource settings.

Who could benefit from this research

Good fit: Children with sickle cell anemia receiving care at participating clinics in Luanda, Angola or Mwanza, Tanzania are the intended participants.

Not a fit: Adults, people without sickle cell anemia, or children who cannot access the two study sites are not expected to benefit from this specific trial.

Why it matters

Potential benefit: If successful, this approach could make hydroxyurea safer and more accessible, leading to fewer sickle cell complications and less frequent laboratory monitoring for children in Africa.

How similar studies have performed: Previous studies, including the team's own prospective work, have shown that pharmacokinetic-guided hydroxyurea dosing can improve outcomes with low toxicity, and this trial expands that approach to African clinical settings.
