Hydroxyurea for the Treatment of Patients With Sickle Cell Anemia

NCT00001197 | Completed Phase 2

• 2 other identifiers: 84002984-H-0029
• Study Type: interventional
• Target: 41
• Locations: 1 country
• Sites: 1

Brief Summary

A total of fifty severely affected patients with homozygous sickle cell disease or other sickling disorders (e.g. B negative or B positive Thalassemia/Sickle) who are greater than 18 years of age will be eligible for treatment. Such patients must be able to tolerate an extensive period without blood transfusion and have relatively well preserved renal and hepatic function (creatinine less than 1.5 mg/dl and normal liver function test with exception of a mild elevation in transaminase). Evidence of severe sickle cell anemia will include recurrent pain crisis, chronic bone oain, evidence of aseptic necrosis with symptoms, and intractable leg ulcer, etc. On admission to the study, each patient will receive a complete history and physical examination. These data and standard laboratory evaluation, including a test for pregnancy if appropriate, will be adequate to ascertain whether any of the criteria for exclusion are present. Each patient must accept responsibility for for using an effective means of contraception. Patients who are found to be HIV positive will be excluded from the study....
