简要总结
Acute Stage: The present study is a randomized, double-blind, placebo-controlled, single-dose, 4-way, cross-over, study. Approximately not more than 170 individuals will be screened and considering a screening failure rate of 25%, approximately 128 individuals will be randomized in a ratio of 1:1:1:1 to receive one of the IPs and will be assigned a unique randomization code. In this stage, approximately 114 individuals will complete the study, after accounting for a dropout/withdrawal rate of 15%. The intervention duration is 4 days [1 (single dose) x 4 periods].
Sub-Acute Stage: The present study is a randomized, double-blind, placebo-controlled, 4 arms, parallel study. In this stage, approximately 112 individuals will be re-randomized in a ratio of 1:1:1:1 to receive one of the IPs and will be assigned a unique randomization code. Each group will have not less than 24 completed participants after accounting for a dropout/withdrawal rate of 15%. The intervention duration is 28 days.

结局指标
主要结局
To determine the effect of EnXtra® and EnXtra® + Caffeine on alertness score as assessed by the change in the Jin Fan Alertness score as compared to placebo and caffeine in Acute stage.
时间窗: Day 15 at 0, 1, 3 and 5 hours ± 15 minutes post IP
The Attention Network Test (ANT) is an assessment tool to evaluate efficacy of three distinct attention networks: alerting, orienting, and executive networks. Alerting effect = mean Response Time (RT) (correct no cue) - mean RT (correct centre cue) Orienting effect = mean RT (correct centre cue) - mean RT (correct spatial cue) Conflict effect = mean RT (correct incongruent) - mean RT (correct congruent) Correct: correctness of response No cue condition: participant does not receive any cue before the target stimulus appears. Spatial cue is usually presented in the form of an arrow, pointing in the location where the target stimulus will show up. Centre cue condition, A cue appears at the screen's center just before the target stimulus. Incongruent: The target stimulus is flanked by distractors oriented in the opposite direction. Congruent: The target stimulus is flanked by distractor stimuli oriented in the same direction.
