Outcome Measures

Primary Outcomes (2)

  • Adult Attention Deficit Hyperactivity Disorder (ADHD) Investigator Symptom Rating Scale (AISRS) Total Score

    Difference between active and placebo for change in Adult ADHD Investigator Symptom Rating total score from baseline to week 6 visit. The minimum score on this scale is 0, the maximum score for the scale is 54 points.Higher numbers indicate more ADHD symptoms, lower scores reflect lower ADHD symptoms.

    six weeks

  • A Priori Definition of Clinical Improvement

    25% reduction in ADHD symptoms as measured by the Adult ADHD Investigator Symptom Rating Scale (AISRS), and a Clinical Global Impression Improvement score of 2 (much) or 1 (very much) improved. The minimum score on the AISRS scale is 0, the maximum score for the scale is 54 points.Higher numbers indicate more ADHD symptoms, lower scores reflect lower ADHD symptoms. The Clinical Global Impression (CGI) Improvement scores range from 0 to 7, with 0=not assessed,1=very much improved), 2=much improved, through to 7=very much worse. Lower scores therefore mean better outcomes.

    six weeks

Study Arms (2)

solriamfetol

EXPERIMENTAL

Participant will receive daily doses of solriamfetol, at 75 mg at week one and 150 mg at week 2, and with intention that dosing remain stable for the last four weeks of study participation, such that investigators will ask a subject to go back down to 75 mg during any of the weeks following week 2 only if only if 150 mg is not tolerated.

Drug: Solriamfetol 75 MGDrug: Solriamfetol 150 MG

PLACEBO COMPARATOR

Participant will receive daily doses of placebo, at 75 mg at week one and 150 mg at week 2, and with intention that dosing remain stable for the last four weeks of study participation, such that investigators will ask a subject to go back down to 75 mg during any of the weeks following week 2 only if only if 150 mg is not tolerated.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults ages 18-65 years of age.
  • A diagnosis of childhood-onset ADHD, meeting the Diagnostic and Statistical Manual-5 (DSM-5) criteria for ADHD in adulthood, including at least 5 current symptoms of inattentive or impulsive-hyperactive traits, and childhood onset by age 12, defined as two symptoms of inattentive or of impulsive/hyperactive traits by the age of 12.
  • A score of 20 or more on the Adult ADHD Investigator Symptom Report Scale (AISRS)

You may not qualify if:

  • Individuals with known renal insufficiency or renal impairment.
  • A history of intolerance to solriamfetol
  • Pregnant or nursing females, and individuals unwilling to use adequate contraceptive methods to avoid conception while they are receiving study agent and for 1 month after the last dose of study agent. For female subjects of childbearing potential adequate contraceptive methods will include: a medically acceptable form of birth control (such as male or female condoms with or without spermicidal agent, diaphragm or cervical cap with spermicide, medically prescribed IUD, hormonal contraceptives like birth control pills, or abstinence). For male subjects this will include use of male condom, being status post vasectomy at least 4 months prior to initiation of study drug exposure, or abstinence during the study.
  • A known unstable major medical illness including hepatic, renal, gastroenterological, respiratory, cardiovascular (including hypertension ≥ 140/90 mmHg), endocrinologic (e.g. thyroid), neurologic (e.g. seizure), immunologic, hematologic, or psychiatric (including an active substance use disorder, psychosis, bipolar disorder, major depression) disorder.
  • Any medical condition that the Principal Investigator (PI) believes will be exacerbated by study participation.
  • A history of cancer (except localized skin cancer without metastases or in situ cervical cancer) within 5 years prior to screening.
  • A known history of narrow-angle glaucoma.
  • Current (within 3 months) DSM-V criteria for abuse or dependence with any psychoactive substance other than nicotine.
  • Multiple adverse drug reactions, defined as previous moderate to severe adverse experiences while on two or more chemically unrelated compounds, where these reactions were unpredictable from the known pharmacology of the drug.
  • Any other concomitant medication with primarily central nervous system activity that are catecholaminergic such as stimulants or atomoxetine, or have strong noradrenergic mechanisms of action such as duloxetine or venlafaxine or buproprion. Subjects may be included who are taking stable doses of agents with primary serotonergic (such as selective serotonin reuptake inhibitors or buspirone), gabaergic (such as gabapentin, pregabalin), or other anticonvulsants. We will also allow participation by individuals with rare (predicted to be less than twice a week) use of prn benzodiazepines or sedative-hypnotics.
  • Current use of MAO Inhibitor or use within the past two weeks.
  • Concomitant medications with high potential for dopaminergic or sympathomimetic effects.
  • Investigator and his/her immediate family; defined as the investigator's spouse, parent, child, grandparent, or grandchild.
  • , Reasonable suspicion of inability, in the judgement of the investigator, to appropriately monitor experiences during the study and take steps to report these experiences or respond in a manner preserving personal health and safety.
  • \. Any condition, including a moderate to severe untreated sleep disorder or other mental health disorder, that renders inability, in the investigator's judgement, to determine whether ADHD symptoms are primarily due to ADHD.
