JRCT ID: jRCT2071240012

Registered date:16/05/2024

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: primary immunoglobulin A nephropathy (IgAN)
• Date of first enrollment: 13/05/2024
• Target sample size: 64
• Study type: Interventional
• Intervention(s): Subjects will be housed the day prior dosing and until at least 36 hours after dosing. There will be 2 periods and at each period, a single, oral 8 mg (2 * 4 mg) or 16 mg (4 * 4 mg) dose of study medication under fasting conditions will take place. There will be at least 7 days but no more than 10 days between dosing times for the treatment periods.

Outcome(s)

• Primary Outcome: The relative bioavailability of VR-205 (budesonide) delayed release capsules 4 mg in Japanese and non-Asian will be determined by a comparison of various pharmacokinetic parameters derived from the plasma concentration-time curves (e.g., AUCL, AUCINF, and CPEAK) of budesonide.
