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.
