Sickle Cell Disease | Effect of Simvastatin Treatment on Vaso-occlusive Pain in Sickle Cell Disease

Sickle Cell Disease research study

What is the primary objective of this study?

The purpose of this study is to determine whether simvastatin is effective in reducing the frequency and intensity of vaso-occlusive pain episodes in patients with sickle cell disease.

Who is eligible to participate?

Inclusion Criteria: - Sickle cell disease (HbSS or S/β0 thalassemia) - ≥ 3 vaso-occlusive pain episodes in the year prior to enrollment - Age ≥ 10 years - Weight > 30 kg Exclusion Criteria: - Creatine kinase (CK) > UNL - Total cholesterol < 90 mg/dL, or triglycerides <30mg/dL - Renal dysfunction (Creatinine > 1.5-fold UNL) - Hepatic dysfunction (ALT > 2-fold UNL) - Treatment with drugs having known metabolic interactions with statins within the past 30 days - Vaso-occlusive pain requiring hospitalization within past 30 days - Red blood cell transfusion within the past 30 days - Pregnancy/lactation - Musculoskeletal disorder associated with an elevated CK level - Past or present history of substance abuse (alcohol, cocaine, amphetamines, heroin) - Chronic pain caused by avascular necrosis of the bone (AVN) or leg ulcers, and pain due to trauma or causes other than SCD. - Major cognitive or neurological impairments that may hamper the ability to use the smartphone or complete the electronic pain diary in this study

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Simvastatin40 mg, orally, once daily for 3 months

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
