What this trial studies

This phase II interventional study aims to assess the pharmacokinetics, efficacy, and safety of Hydroxycarbamide dispersible tablets administered twice daily to children aged 9 months to 11 years with Sickle Cell Disease. Participants will take the medication daily for 12 months and attend clinic visits at specified intervals for monitoring. The study is non-randomized and open-label, focusing on children who are naïve to Hydroxycarbamide treatment.

Who should consider this trial

Good fit: Ideal candidates are children aged 9 months to 11 years with HbSS or HbSβ0 Sickle Cell Disease who have not previously received Hydroxycarbamide.

Not a fit: Patients currently participating in other clinical trials or those with contraindications to Hydroxycarbamide will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for managing Sickle Cell Disease in children.

How similar studies have performed: Previous studies have shown promising results with Hydroxycarbamide in treating Sickle Cell Disease, indicating potential for success in this approach.
