Brief summary: This is a 6 week efficacy and safety study of Dasotraline in subjects 6 to 12 years old with ADHD.

Detailed description: This is a randomized, double blind, multicenter, placebo-controlled, parallel group, outpatient study evaluating the efficacy and safety of dasotraline in subjects 6 to 12 years of age with ADHD using 2 doses of dasotraline (2 mg/day and 4 mg/day) versus placebo over a 6 week treatment period. The study will consist of screening, treatment, and end of study visits.

Eligibility criteria: Inclusion Criteria:

* Subject's parent/legal guardian must give written informed consent, including privacy authorization, prior to study participation. The subject will complete an informed assent prior to study participation.
* Subject and the subject's parent/legal guardian must be judged by the investigator to be willing and able to comply with the study procedures and visit schedules.
* Subject, male or female, must be between 6 and 12 years of age, inclusive, at the time of consent/assent and at Baseline.
* Subject meets Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM 5) criteria for a primary diagnosis of ADHD (inattentive, hyperactive, or combined presentation) at screening established by a comprehensive psychiatric evaluation that reviews DSM 5 criteria is confirmed using the K-SADS-PL at Screening.
* Subject has an ADHD RS IV HV score of ≥ 28.
* Subject has a CGI S score of ≥ 4.
* Subject, if female, must not be pregnant or breastfeeding, and if ≥ 8 years of age must have a negative pregnancy test.
* Female subject:

  * must be unable to become pregnant (eg, premenarchal, surgically sterile, etc);

OR

• practice true abstinence (consistent with lifestyle) and must agree to remain abstinent from signing informed consent/assent to at least 14 days after the last dose of study drug has been taken;

OR

• is sexually active and willing to use a medically effective method of birth control (see Appendix VII) from signing informed consent/assent to at least 14 days after the last dose of study drug has been taken.

* Male subject must be willing to remain sexually abstinent (consistent with lifestyle) or be using an effective method of birth control from signing informed consent/assent to at least 14 days after the last dose of study drug has been taken.
* Subject must be in general good health (defined as the absence of any clinically relevant abnormalities as determined by the Investigator) based on screening physical and neurological examinations, vital signs, medical history, and clinical laboratory values (hematology, chemistry, and urinalysis). Note: If any of the hematology, chemistry, or urinalysis results are not within the laboratory's reference range, then the subject may be included only if the investigator determines the deviations to be not clinically relevant.
* Subject weighs at least 21 kg and is within 3rd to 97th percentile for gender specific body-mass-index (BMI)-for-age from the World Health Organization (WHO) growth charts (see Appendices II and IX).
* Subject's parent/legal guardian must report a history of the subject being able to swallow capsules.
* Subject and subject's parents/legal guardians must be able to fully comprehend the informed consent/assent form (as applicable), understand all study procedures, and be able to communicate satisfactorily with the Investigator and study coordinator.

Exclusion Criteria:

* Subject currently has a diagnosis of asthma that has required daily treatment with bronchodilators or nebulizer treatments in the 30 days prior to screening and/or who may require daily treatments with these agents over the course of the trial. Intermittent use of bronchodilators is not exclusionary. Subjects who have a history of requiring persistent asthma treatment should be discussed wit the medical monitor prior to enrolment.

Note: Active medical conditions that are minor or well-controlled are not exclusionary if they do not affect risk to the subject or the study results. In cases in which the impact of the condition upon risk to the subject or study results is unclear, the Medical Monitor should be consulted. Any subject with a known cardiovascular disease or condition (even if controlled) must be discussed with the Medical Monitor during screening.

Past history of febrile seizure, drug-induced seizure, or alcohol withdrawal seizure is exclusionary. Subject taking anticonvulsants for seizure control currently or within the past 2 years is not eligible for study participation.

* Subject has any history of attempted suicide, in the opinion of the investigator.
* Subject does not tolerate venipuncture or has poor venous access that would cause difficulty for collecting blood samples.
