Time to Relapse From Date of Randomization to Endpoint of The Randomized-withdrawal Period |
Relapse status was assessed during the double-blind treatment phase and was defined as having 2 or more binge days per week for 2 consecutive weeks (14 consecutive days) prior to any visit and having an increase in Clinical Global Impressions-Severity (CGI-S) score of 2 or more points compared to the randomized-withdrawal baseline (date of relapse - date of randomization). Binge eating information was captured via a self-report paper diary. The binge diary captured the number of binges per day, total hours per day spent binging, type of binge (at mealtime or at another time other than mealtime), and a description of the binge (amounts and types of foods). Binge frequency was reviewed by the clinician with the subject to confirm reported binge episodes per day. The CGI-S was performed to rate the severity of a subject's condition using a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill). |

Change From Randomized-Withdrawal Baseline in The Number of Binge- Eating Days Per Week During The Randomized-withdrawal Period |
A binge day was defined as days during which at least 1 binge episode occurred. As assessed by clinical interview based on subject binge diary. Binge eating information was captured via a self-report paper diary. The binge diary captured the number of binges per day, total hours per day spent binging, type of binge (at mealtime or at another time other than mealtime), and a description of the binge (amounts and types of foods). Binge frequency was reviewed by the clinician with the subject to confirm reported binge episodes per day. A negative change from Baseline indicates that binge-related behavior decreased. The randomized -withdrawal-baseline was defined as the weekly average number of binge days for the 14 days prior to the Randomization Visit (Visit 8). |

Percent of Participants Within Each Category of The Clinical Global Impression-Severity of Illness (CGI-S) Scale at Endpoint of The Randomized-withdrawal Period |
The CGI-S permits a global evaluation of a subject's condition and severity of symptoms. The CGI-S was performed to rate the severity of a subject's condition based on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill). |

Change From Randomized-Withdrawal Baseline in The Total Score of The Yale-Brown Obsessive Compulsive Scale Modified for Binge Eating (Y-BOCS-BE) During The Randomized-withdrawal Period |
The Y-BOCS-BE measures the obsession of binge eating thoughts and compulsiveness of binge eating behaviors. The scale is a clinician rated, 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms). The scale includes questions regarding the amount of time spent on obsessions, impairment or distress experienced, and resistance and control over these thoughts. The same types of questions were asked about compulsions (ie, time spent, interference, etc.).Total scores range from 0 to 40. A total score of 0-7 is sub-clinical, 8-15 is mild, 16-23 is moderate, 24-31 is severe, and 32-40 is extreme. A decrease from baseline in Y-BOCS-BE Total Score represents an improvement in obsession with binge-eating thoughts or compulsiveness of binge-eating behaviors. |

Number of Participants With a Positive Response on The Columbia Suicide Severity Rating Scale (C-SSRS) at Endpoint of The Open-label Period |
The C-SSRS is a semistructured interview that captures the occurrence, severity, and frequency of suicide-related thoughts and behaviors. The interview includes definitions and suggested questions to solicit the type of information needed to determine if a suicide-related thought or behaviour occurred. The interview was initiated with 5 (yes/no) questions, presented in ascending order of severity, about suicidal ideation. The most severe type of ideation was rated for frequency, duration, controllability, deterrents, and reason. If the answer to the first 2 ideation questions was "yes," the clinician asked questions 3-5. Active suicidal ideation included any participant who answered "yes" to questions 2-5. If the answers to ideation questions 1 and 2 were "No," then the clinician proceeded to 5 (yes/no) questions that addressed suicidal behavior, which was categorized as actual attempt, interrupted attempt, aborted attempt, preparatory acts or behaviors, and completed suicide. |

Total Scores For The Amphetamine Cessation Symptom Assessment (ACSA) Scale During Follow-up |
The ACSA was used in this study to assess potential withdrawal symptoms associated with chronic use of SPD489. The ACSA is a self-completed scale used to assess withdrawal symptoms. The scale has 16 symptom items rated on a 5-point scale ranging from 0 (not at all) to 4 (extremely). The ACSA total score ranges from 0-64, where a higher score indicates greater withdrawal symptom severity. |
