Hydroxyurea to Prevent Central Nervous System (CNS) Complications of Sickle Cell Disease in Children

Johns Hopkins University·interventional·Posted Jul 7, 2011·Updated Jul 10, 2024

In Brief

A Phase 2 clinical trial evaluating Hydroxyurea and Placebo for Sickle Cell Disease and Stroke. Completed, enrolled 28 participants across 5 sites.

Detailed Summary

This is a pilot study of hydroxyurea versus placebo to reduce central nervous system complications (abnormally fast blood flow to the brain, silent cerebral infarct or stroke) in young children with sickle cell disease. The investigators plan to identify children 12 to 48 months old without central nervous system complications and randomly assign 20 to treatment with hydroxyurea and 20 to treatment with placebo for 36 months. Neither the study doctors nor the participants will know which treatment they are receiving.

Hydroxyureadrug

Hydroxyurea solution 100 mg/ml with a starting dose of 20 mg/kg/day by mouth once daily and escalation by 5 mg/kg/day every 8 weeks until hematological toxicity, an Absolute Neutrophil Count of 2000 to 4000/ul, or a maximum dose of 35 mg/kg/day.
