Simvastatin (Zocor) Therapy in Sickle Cell Disease

Status Completed

Clinical Trial Summary

Recent clinical and experimental data indicate that statins have effects beyond cholesterol lowering that may be beneficial in sickle cell disease by protecting the vascular endothelium. Statins have been shown to attenuate endothelial dysfunction through their anti-inflammatory, anti-oxidant and anti-thrombotic properties. This phase I/II dose-escalating trial is designed to assess the safety and potential clinical efficacy of oral simvastatin (Zocor)in adolescents and adults with sickle cell disease (SCD).

Clinical Trial Description

Although statins have been used extensively for their cholesterol-lowering effects, recent clinical and experimental data indicate that statins regulate yet other processes, many of which play a major role in sickle cell disease (SCD). Independent of their cholesterol-lowering effects, statins have been shown to prevent damage to blood vessels in several ways, through upregulation of endothelial nitric oxide (NO)and decreased inflammation. Numerous studies documenting the protective effects of statins, together with data showing the therapeutic role of NO in SCD, provide the basis for investigating the potential clinical benefit of simvastatin in SCD.

Data supporting the safety and tolerability of simvastatin in patients with SCD are now needed. For this phase I/II dose-escalation study of oral simvastatin in SCD, we propose the following specific aims:

1. To obtain preliminary efficacy data on the effects of oral simvastatin on plasma biomarkers of endothelial injury in patients with SCD, and

2. To assess the safety and tolerability of oral simvastatin in patients with SCD. ;
