Evaluating the Safety and Tolerability of Orally Administered DF-003 in ROSAH Syndrome Patients
brief summary
The purpose of this study is to evaluate the safety and tolerability of DF-003 in retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and migraine headache (ROSAH) syndrome patients.
detailed description
This is a Phase Ib open-label, single-arm, single-dose study that will be conducted in up to 12 ROSAH syndrome patients. The study will investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of DF-003 (study drug). DF-003 will be administered orally (PO), once daily (QD) for 28 days (4 weeks). Patients will be followed up for 8 weeks after administration of the last dose of study drug.
A total of 8 patients will be evaluated in one cohort. The cohort will have a minimum of 6 patients. Additional patients (maximum of 12 patients) may be enrolled in the event of insufficient data after a review of safety data by the Study Safety Committee. Patients will receive loading doses of 140 mg DF-003 on Days 1, 2, and 3, followed by a maintenance dose of 45 mg DF-003 starting on Day 4 through Day 28. Individual dose modification is not allowed in this study.
