About

The purpose of this study is to evaluate the effect of the potent CYP3A4 inhibitor itraconazole on the single-dose PK of TAK-954.

Full description

The drug being tested in this study is called TAK-954. TAK-954 is being tested in healthy participants in order to evaluate the effect of the potent CYP3A4 inhibitor itraconazole on the single-dose PK of TAK-954.

The study will enroll approximately 10 participants. Participants will receive the following treatment sequences:

• TAK-954 0.2 mg; Itraconazole 200 mg + TAK-954 0.2 mg

Participants will be given an intravenous infusion of TAK-954 on Day 1 of First Intervention Period (6 days) followed by minimum 7-day washout period, after which participants will be given Itraconazole capsule on Days 1 to 8 along with TAK-945 infusion on Day 4 of Second Intervention Period (9 days).

This single center trial will be conducted in the United States. The overall duration to participate in this study is 7 to 8 weeks. Participants will visit the clinic on Day -1 and remained confined until Day 6 (First Intervention Period) and Day 9 (Second Intervention Period). Participants will return for a Follow-up Visit 10 to 14 days after last dose of study drug (approximately up to Day 34).
