Eligibility
Inclusion criteria
* Capable of providing written informed consent prior to initiation of any trial-related procedures, and able, in the opinion of the investigator, to comply with all requirements of the trial
Exclusion criteria

Pre-assignment details
A total of 33 subjects were screened for participation in this trial. Of the 33 subjects, 18 subjects were enrolled and randomized to one of 3 sequences, each consisting of 6 subjects. Of the 6 subjects in the Sequence 1 group, 6 subjects received a single dose of OPC-34712 orally disintegrating tablet (ODT) without water, 5 subjects received a single dose of OPC-34712 conventional tablet, and 4 subjects received a single dose of OPC-34712 ODT with water.
Participants by arm
| Arm | Count |
|---|---|
| Sequence 1 Subjects randomized to Sequence 1 received an ODT without water on Day 1, a conventional tablet on Day 21, and an ODT with water on Day 41. | 6 |
| Sequence 2 Subjects randomized to Sequence 2 received an ODT with water on Day 1, an ODT without water on Day 21, and a conventional tablet on Day 41. | 6 |

Outcome results
Area Under the Concentration-time Curve From Time Zero to Infinity (AUC∞) of OPC-34712
To evaluate AUC∞ of OPC-34712 4-mg ODT formulation relative to 4-mg conventional tablet formulation
Time frame: Predose, 1, 2, 3, 4, 5, 6, 8, 12, 16, 24, 48, 72, 96, 120,144, 168, 216, 264, and 312 hours postdose
Population: Pharmacokinetic analysis set consisted of subjects with all evaluable PK parameters from enrolled subjects who had evaluable plasma concentrations. No data imputation was done for missing data, ie, missing data remained missing for the analyses.
