5. Study Description
Brief Summary
The purpose of this study is to determine the safety of a new formulation of the omega-3 fatty acids Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) and to assess whether it decreases inflammation and inflammatory pain in children and young adults with Sickle Cell Disease.

Intervention Name(s)
SCD-Omegatex™
Other Intervention Name(s)
Enteric Fish Oil 250 DHA/27 EPA Soft Gelatin Capsule
Intervention Description
Subjects will receive SCD-Omegatex™ (Enteric Fish Oil 250 DHA/27 EPA Soft Gelatin Capsule, 450 mg) at one of two daily doses, orally, once a day for 6 months. The trial will follow a "3+3" design using two dose levels. In the phase I portion, subjects will be treated with a dose of 25 mg/kg/day DHA and EPA. If this is tolerated without dose limiting toxicity (DLT), a subsequent cohort of patients will be treated at a dose of 37.5 mg/kg/day with a maximum total daily dose of 4 grams. Once a maximum tolerated dose (MTD) is determined, subjects on the phase II portion of the study will be treated at that dose.
