You may qualify if…

Subjects with non-impaired hepatic function must meet all of the following criteria:
Male or nonpregnant, nonlactating female between 18 and 70 years of age.
Subject must have a normal neurologic exam including tests for impending hepatic encephalopathy.
Subject's weight is at least 50 kg.
Subject's body mass index (BMI) is at least 18 kg/m2 but no more than 37 kg/m2
Subject must be in general good health be demographically comparable to a least 1 subject with hepatic impairment who completed the study.
Subject has a negative urine drug screen (UDS).
Subjects with hepatic impairment must meet all of the following criteria:
Male or nonpregnant, nonlactating female between 18 and 70 years of age.
Subject must have a normal neurologic exam including tests for impending hepatic encephalopathy. Note: Subjects with grade 0 or 1 hepatic encephalopathy will be considered for enrollment in the study.
Subject's weight is at least 50 kg.
Subject's BMI is at least 18 kg/m2 but no more than 37 kg/
Subject has a negative UDS.
Subject with stable, chronic medical conditions (eg, hypertension and hyperlipidemia) in addition to hepatic impairment that, in the opinion of the investigator, will not significantly alter the disposition of the study drug, will not place the subject at increased risk by participating in the study, and will not interfere with interpretation of the data may be permitted to enroll in the study after discussion and agreement between the investigator and medical monitor.
Subject exhibits vital signs within the reference range for their age and level of hepatic impairment; subjects with vital signs outside the reference ranges may be eligible for the study if the investigator and medical monitor agree that the results are not clinically significant based on the age and hepatic impairment status of the subject, and will not impact study conduct.
Subject with out-of-range laboratory results that are related to the subject's underlying condition are eligible; however, the results will need to be carefully reviewed by the investigator and medical monitor to determine if a subject is eligible for study participation. Out of range results could indicate a stable or unstable situation. If the subject is unstable (eg, rapidly changing liver tests, significantly worsened anemia compared to earlier labs, etc), then such subject would be excluded from study participation. Serum bilirubin, albumin, and prothrombin time will be assessed individually for a point score according to the Child-Pugh classification.
Subject has a diagnosis of chronic hepatic impairment for at least 6 months and, in the opinion of the investigator, the severity of the subject's hepatic disease is stable, which is defined as having no clinically significant change in disease status within the 90 days prior to study drug administration, as documented by the subject's recent medical history. Copies of documentation of any clinical information used to make a previous diagnosis of hepatic dysfunction must be available. This may include abnormal liver function tests, clinical evidence of portal hypertension, a positive liver biopsy (eg, for cirrhotic disease, portal hypertension), and/or hepatic ultrasound.
The total score of the Child Pugh classification must be 5 or 6 for subjects with mild hepatic dysfunction, and between 7 and 9, inclusive, for subjects with moderate dysfunction, and between 10 and 12, inclusive, for subjects with severe hepatic dysfunction.
Subject receiving medication for underlying disease states or medical conditions related to hepatic dysfunction must be on a stable dose of medication and/or treatment regimen. Subjects who are receiving a fluctuating treatment regimen may be considered for inclusion if, in the opinion of the investigator, the underlying disease is under control; however these subjects must have medical monitor approval.
Subject with a history of hepatic impairment due to hepatitis B is eligible provided there is no evidence of an active disease state, defined as a positive hepatitis B antigen test at screening.
Subject with a history of alcohol abuse is eligible provided the urine alcohol test is negative.
Subject with a history of type 2 diabetes mellitus is eligible provided that, in the investigator's opinion, he or she has stable diabetes.

You may not qualify if…

Any subject with non-impaired hepatic function meeting any of the following criteria will be excluded:
Subject who does not tolerate venipuncture or has poor venous access that would cause difficulty for collecting blood samples.
Subject has any clinically significant unstable medical abnormality, chronic disease, or history of clinically significant abnormality of the cardiovascular, respiratory, hepatic or renal systems.
Subject has any clinically significant abnormal medical history, physical examination, ECG, or laboratory results.
Subject has estimated creatinine clearance ≤ 60 mL/min according to the Cockcroft Gault equation.
Subject has had an acute illness within 30 days prior to administration of study drug.
Subject who, within 14 days prior to administration of study drug, has had a febrile illness.
Subject has a disorder or history of a condition that may interfere with drug absorption, distribution, metabolism or excretion including clinically significant abnormality of the hepatic or renal system, a history of malabsorption, or previous gastrointestinal surgery that could affect drug absorption or metabolism.
Subject has a presence or history of any medically diagnosed, clinically significant psychiatric disorder (including intellectual disability and substance-related disorders).
Subject answers "yes" to "Suicidal Ideation" Items 4 or 5 on the C SSRS. Subjects who have significant findings for suicidal ideation upon completion of the C SSRS must be referred to the investigator for follow-up evaluation.
Female subject who is pregnant, lactating, or within 6 months postpartum.
Subject tests positive at screening for the hepatitis B surface antigen or hepatitis C antibody or human immunodeficiency virus (HIV 1 or HIV 2) antibody.
Subject has a positive urine alcohol test.
Subject has history of substance-related disorder or alcohol related disorder as defined by Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM 5) criteria within 1 year prior to screening.
Subject has an average weekly alcohol intake that exceeds 21 units per week (males up to age 65) and 14 units per week (males over age 65 and females). 1 unit = 12 oz or 360 mL of beer; 5 oz or 150 mL of wine; 1.5 oz or 45 mL of distilled spirits.
Subject is unwilling to stop alcohol consumption for at least 4 hours prior to admission on Day -1 (as confirmed by breath or urine alcohol test) through Day 7.
Subject who has previously received dasotraline.
Subject has history of intolerance to stimulants.
Subject has history of allergic reaction or has a known or suspected sensitivity to any substance that is contained in the study drug formulation.
Subject has had significant blood loss (> 500 mL) or donated blood, plasma, or other blood products within 30 days prior to administration of study drug.
Subject has used any drugs known or suspected to affect hepatic or renal clearance capacity within 30 days prior to administration of study drug.
Subject has taken any prescription or over-the-counter (OTC) medications, herbal tea, energy drinks, herbal products (eg, St John's Wort, milk thistle, etc) or supplement/supra-therapeutic doses of vitamins within 5 half lives or 14 days (whichever is longer) prior to administration of study drug or is anticipated to need any medication during the study, with the exception of those permitted by the protocol or approved by the investigator and medical monitor.
Subject has taken any investigational drug within 30 days or 5 half lives (whichever is longer) prior to administration of study drug.
Subject is currently a heavy user of nicotine, ie, smoking more than 20 cigarettes (eg, 1 pack) per day or equivalent (eg, e-vapor cigarette, pipe, cigar, chewing tobacco, nicotine patch or nicotine gum).
Subject cannot comply with the smoking restrictions of the study site during the confinement period or is unable or unwilling to refrain from smoking and tobacco use for 2 hours prior to study drug administration and 4 hours following administration.
