Promoting Utilization & Safety of Hydroxyurea Using Precision in Africa

Status Recruiting

Clinical Trial Summary

Sickle cell anemia (SCA) is among the world's most common and devastating blood disorders, affecting more than 300,000 newborns per year. Most infants with SCA are born in the low-resource settings of sub- Saharan Africa, where an estimated 50-90% will die before 5 years of age due to lack of early diagnosis and appropriate care. Hydroxyurea is a safe and effective once-daily oral medication that has become the standard of care for the treatment of children with SCA in high-resource settings. There is now a growing body of evidence to support the safety and clinical benefits of hydroxyurea for the treatment of SCA in sub-Saharan Africa. The requirement for frequent laboratory monitoring, uncertainties about appropriate, most effective dosing, and the concern for hematologic laboratory toxicities, however, will continue to limit widespread hydroxyurea utilization and real-world effectiveness. The investigators have recently developed and prospectively evaluated an individualized, pharmacokinetics-guided hydroxyurea dosing strategy for children with SCA that has demonstrated optimal clinical and laboratory benefits with minimal toxicity. In this research study, the investigators aim to extend this precision medicine approach to Africa.

Clinical Trial Description

The Promoting Utilization and Safety of Hydroxyurea Using Precision in Africa (PUSHUP) trial is a prospective, randomized clinical trial of hydroxyurea for 400 children with SCA in Luanda, Angola. The study will prospectively evaluate the safety and efficacy of hydroxyurea with limited laboratory monitoring and will bring precision medicine to children with SCA using several novel features including measurement of hydroxyurea using a battery-powered HPLC machine and individualized dose calculations using an automated computer-based algorithm. The objective of this study is to establish evidence-based guidelines for hydroxyurea in sub-Saharan Africa, including appropriate dosing and laboratory monitoring strategy with the goal of allowing for widespread use of hydroxyurea across sub-Saharan Africa, regardless of clinical or laboratory resources. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
