Inclusion criteria
* Male or female subject between 18 and 55 years of age, inclusive, at time of informed consent. * Subject meets the following DSM 5 criteria for a diagnosis of BED. An episode of binge eating is characterized by both: * Eating an amount of food larger than what most people would eat, in a discrete period of time (eg, 2 hours) * Sense of lack of control over eating episode * Binge-eating episodes are associated with ≥ 3 of the following: * Eating much more rapidly than normal * Eating until uncomfortably full * Eating large amounts when not feeling hungry * Eating alone because of embarrassment * Feeling disgusted with oneself, guilty afterward * Binge-eating episodes are also associated with marked distress regarding the episode and not associated with recurrent use of compensatory behavior (eg, bulimia nervosa). * Diagnosis is confirmed based on the eating-disorders module of the SCID, clinician review of subject diaries, and the EDE Q. * Subject has a BED diagnosis including at least 2 binge eating days a week for at least 6 months prior to screening. * Subject's BED is of at least moderate severity. * Subject has a negative breath alcohol test and a negative urine drug screen (UDS) for any illicit drug. * Female subject must have a negative serum pregnancy test at screening; females who are post-menopausal (defined as at least 12 months of spontaneous amenorrhea) and those who have undergone hysterectomy or bilateral oophorectomy will be exempted from the pregnancy test. * Female subject of childbearing potential and male subject with female partner of childbearing potential must agree to use an effective and medically acceptable form of birth control throughout the study period. Note: Continued use of an effective and medically acceptable form of birth control is recommended for 30 days after study completion. * Subject must be able to comply with study drug administration and adhere to protocol requirements. Subject can read well enough to understand the informed consent form and other subject materials.

Subjects who answer yes to this question must be referred to the Investigator for follow up evaluation. * Subject has type I diabetes mellitus or insulin-dependent diabetes mellitus. * Subject with type II diabetes mellitus has hemoglobin A1c ≥ 6.5% at screening, or has initiated treatment with or changed the dose of a glucose-lowering agent within 3 months prior to screening. * Subject has known history of symptomatic cardiovascular disease, advanced arteriosclerosis, structural cardiac abnormality, cardiomyopathy, documented heart rhythm abnormalities, coronary artery disease, or other serious cardiac problems. * Subject has initiated treatment with or changed the dose of a lipid-lowering medication within the 3 months prior to screening. * Subject has a history of moderate or severe hypertension that in the investigator's opinion has not been medically stable or has required a change in dosage and/or medication during the 3 months prior to screening. * Subject has a history of epilepsy, seizures (except childhood febrile seizures), unexplained syncope or other unexplained blackouts (except single incident), or head trauma with loss of consciousness lasting more than 5 minutes, or a history of clinically significant repeated head-traumas without loss of consciousness. * Subject is female and pregnant or nursing. * Subject has had bariatric surgery, lap bands, duodenal stents, or other procedures for weight loss. * Subject has a history of positive test for Hepatitis B surface antigen or Hepatitis C antibody with liver function test results at screening above the upper limit of normal (ULN) for the reference laboratory. * Subject without a history of positive test for Hepatitis B surface antigen or Hepatitis C antibody has alanine aminotransferase (ALT) or aspartate aminotransferase (AST) value ≥ 2 times the ULN at screening. * Subject has a blood urea nitrogen (BUN) value ≥ 1.5 times the ULN for the reference range, fasting blood glucose ≥ 126 mg/dL (7.0 mmol/L), or hemoglobin A1c ≥ 6.5% at screening. * Subject is known to have tested positive for human immunodeficiency virus (HIV). * Subject has a clinically significant abnormality on screening evaluation including physical examination, vital signs, ECG, or laboratory tests that the investigator considers to be inappropriate to allow participation in the study. * The subject's screening ECG shows a corrected QT interval using Fridericia's formula (QTcF) of ≥ 450 msec for male subjects or ≥ 470 msec for female subjects. Eligibility will be based on the core laboratory ECG interpretation report. * Subject has any life-time history of abuse or diversion of stimulants. * Subject has a history of allergic reaction or has a known or suspected sensitivity to any substance that is contained in the study drug formulation. * Subject has enrolled in any Phase 2 or 3 trial of psychostimulants including lisdexamfetamine dimesylate (Vyvanse®) for binge-eating disorder. * Subject is currently participating or has participated in any clinical trial within the last 90 days or has participated in more than 2 clinical trials within the past year.
