研究概览
简要总结
This is a single-center, 2-part, non-randomized, open-label study of the drug-drug interactions of belumosudil (KD025) with itraconazole, rifampicin, rabeprazole, and omeprazole in healthy male subjects.
详细描述
Part 1:
The primary objective of Part 1 of this study is to determine the effect of itraconazole, rifampicin, and rabeprazole on the pharmacokinetics of once daily (QD) orally administered belumosudil in healthy male subjects. Part 1 consists of 4 periods.
In each study period, subjects will receive a single dose of belumosudil, in the fed state. Additionally, in order to assess the effects of inhibition and induction of CYP3A4 and the elevation of gastric pH on belumosudil exposure, subjects will receive multiple doses of perpetrator drugs in Periods 2 to 4; a strong CYP3A4 inhibitor, itraconazole, in Period 2; a proton pump inhibitor, rabeprazole, in Period 3; and a strong CYP3A4 inducer, rifampicin, in Period 4.
Subjects will receive a total of 4 single oral dosses of investigative product (IP), 200 mg belumosudil QD, in the fed state over 4 periods (each lasting 3 days with a minimum washout of 2, 8, and 4 days following completion of Periods 1, 2, and 3, respectively). Subjects also will receive 9 single oral doses of itraconazole 200 mg (QD over 9 days) in Period 2; 7 single oral doses of rabeprazole 20 mg (BID over 3 days followed by QD on 1 day) in Period 3; and 9 single doses of rifampicin 600 mg (QD over 9 days) in Period 4.
A follow-up visit will take place 3 to 5 days post-final discharge.
