A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose, 3-Period, Incomplete Block Design Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of TAK-954 in Healthy Adult Participants

The purpose of this study is to evaluate the safety, tolerability, and PK of single ascending
intravenous doses of TAK-954.

The drug being tested in this study is called TAK-954. This study will assess the safety,
tolerability, PK and PD of single ascending TAK-954 higher intravenous doses than those
previously studied.

The study will enroll approximately 6 participants. Participants will be randomly assigned
(By chance, like flipping a coin) to one of the three treatment groups—which will remain
undisclosed to the participant and study doctor during the study (unless there is an urgent
medical need).

Participants will be randomized to one of the 3 treatment sequences. In each treatment
sequence, each participant will receive 2 doses of active drug out of 3 dose levels (TAK-954
0.5 mg, TAK-954 1 mg, or TAK-954 2 mg) and 1 dose of Placebo. Dose escalation will be based
on the available safety/tolerability data from the previous period.

This single center trial will be conducted in the United States. The overall time to
participate in this study is approximately 73 days. Participants will make a final visit on
Day 16 after receiving their last dose of study drug for a follow-up assessment.

Inclusion Criteria:

1. Body mass index (BMI) greater than or equal to (>=) 18 and less than or equal to (<=)
32 kilogram per square meter (kg/m^2), weighing >=50 kilogram (kg) at screening.

2. Medically healthy with no clinically significant medical history, physical
examination, laboratory profiles, vital signs, orthostatic vital signs, or ECGs, as
deemed by the Investigator or designee.

3. Continuous non-smoker who has not used nicotine-containing products for at least 3
months prior to the first dose and throughout the study, based on participant
self-reporting.

Exclusion Criteria:
