|Condition or disease||Intervention/treatment||Phase|
|Sickle Cell Disease||Drug: L-citrulline tablets, 1000 mg||Phase 1|
Phase 1, single center, open label, multiple-dose study consisting of a screening period followed by four weeks of treatment. At least 12 male and female patients, 10 years of age or older, with sickle cell disease but otherwise healthy, will be enrolled in the study.
PK measurements include plasma concentrations of L-citrulline, L-arginine, L-ornithine, and L-proline following the first dose of orally administered L-citrulline and after four weeks of twice daily administration of the drug.
PD measurements include intercellular and vascular adhesion molecules (ICAM, VCAM, and E-selectin), surrogate markers of sickle cell disease activity, and PAT, a measurement of vascular function.
|Study Type :||Interventional (Clinical Trial)|
|Enrollment :||12 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Phase 1 Pharmacokinetic and Pharmacodynamic Responses to Oral L-Citrulline in Patients With Sickle Cell Disease|
- PK and PD responses to L-citrulline
- Endpoints will be determined as change from baseline
- Assessment of safety and tolerability of L-citrulline,
