This study is to evaluate the effects of single therapeutic and supratherapeutic oral doses of ACP-196 on the heart rate-corrected QT interval using Fridericia's formula (QTcF).
This is a single-dose, randomized, double-blind, double-dummy, placebo- and positive-controlled, 4-period, balanced crossover study under fasting conditions. Participants will be randomized to 1 of 4 treatment sequences: ABCD, BDAC, CADB, or DCBA. On 4 different occasions (4 periods), each participant will receive Treatment A (a single therapeutic oral dose of 100 mg ACP-196), Treatment B (a single supratherapeutic oral dose of 400 mg ACP-196), Treatment C (a single oral dose of 400 mg moxifloxacin) or Treatment D (a single oral dose of ACP-196 and moxifloxacin matching placebos) according to a randomization scheme. The washout period will be \>= 5 days between each dose. The clinic attempted to contact participants using their standard procedures approximately 14 days after the last study drug (or placebo) administration to determine if any adverse events (AEs) had occurred since the last dose of study drug(s). An adverse event is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.

Participants will receive a single oral dose of 100 mg ACP-196 (1 x 100 mg capsule) on Day 1 (Treatment A) and 400 mg ACP-196 (4 x 100 mg capsules) on Day 1 (Treatment B) according to the randomization scheme.
Participants will receive a single oral dose of 400 mg moxifloxacin (1 x 400 mg tablet) on Day 1 (Treatment C) according to the randomization scheme.
Participants will receive a single oral dose of ACP-196 matching placebo (4 x 100 mg matching placebo capsules) and moxifloxacin matching placebo (1 x 400 mg matching placebo tablet) on Day 1 (Treatment D) according to the randomization scheme.
