Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the dose strength equivalence of to-be-marketed (TBM) centanafadine (CTN) once daily (QD) extended release (XR) when administered as 2 capsules of 164.4 milligrams (mg) or as a single capsule of 328.8 mg, effect of food on the absorption of the TBM CTN QD XR capsule, and relative bioavailability of clinical (Clin) CTN sustained release (SR) tablets to the TBM CTN QD XR capsules.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Body mass index (BMI) between 19.0 to 32.0 kilograms per square meter (kg/m\^2) (inclusive).
2. In good health as determined by:

* Medical history
* Physical examination
* Electrocardiogram (ECG)
* Serum/urine chemistry, hematology, and serology tests.
3. Ability to provide written, informed consent prior to initiation of any trial-related procedures, and ability, in the opinion of the investigator, to comply with all the requirements of the trial.

Exclusion Criteria

1. Clinically significant abnormality in past medical history, or at the screening physical examination, that in the investigator's or sponsor's opinion may place the participant at risk or interfere with outcome variables including absorption, distribution, metabolism, and excretion of drug. This includes, but is not limited to, history of or concurrent cardiac, hepatic, renal, neurologic, endocrine, gastrointestinal, respiratory, hematologic, and immunologic disease or cholecystectomy.
2. History of drug and/or alcohol abuse within 2 years prior to screening.
3. History of or current hepatitis or AIDS or carriers of hepatitis B surface antigen (HBsAg) and/or hepatitis C antibodies (anti-HCV), or HIV antibodies.
4. History of any significant drug allergy or known or suspected hypersensitivity.
5. A positive urine or breath alcohol test and/or urine drug screen for substance of abuse at screening or upon admission to the trial site.
6. Any participant who, in the opinion of the investigator, should not participate in the trial.
