Age >= 18 and =26 at screening. 5. CGI-S score of >=4 at screening. 6. Must be willing to receive IMP dose twice weekly. On Day 1, the subject will come to the clinic and must be willing to take a taxi or public transportation home or be accompanied by a caregiver and not drive a car, use heavy equipment, or participate in any other dangerous activity for the remainder of the day after receiving IMP (NOTE: at any protocol visit after Day 1 dosing, dosing visits may occur at the subject*s home at the discretion of the PI, conducted by one of the study investigators or delegate and administered under supervision followed by the performance of the same procedures done at the clinic including safety monitoring. If early withdrawal is considered due to any safety issue identified, the Sponsor*s medical monitor should be notified. If a remote visit is conducted due to any reason related to the COVID-19 pandemic, notification must be sent to the Medical Monitor*s dedicated email address and Urgent Safety Measures as outlined in this protocol must be followed.) 7. Must be willing to refrain from more than 6 standard alcoholic drinks per week (1 standard drink corresponds to 0.1 L wine, 0.3 L beer, or 4 cL liquor), more than 10 cigarettes a day, and more than 2 cups of coffee a day throughout the study treatment period (6 weeks) and until the last study visit is complete (EoS or ET).

Exclusion criteria: 1. Past or present diagnosis of a primary psychotic disorder or first-degree relative with a psychotic disorder. 2. Past or present bipolar disorder (DSM-5). 3. Other current psychiatric disorders that, in the opinion of the Investigator or medical supervisor, may confound the results of the study (e.g., obsessive-compulsive disorder, dysthymic disorder, panic disorder, dissociative disorder, anorexia nervosa or bulimia nervosa). 4.

Any clinically significant abnormal metabolic or hematologic screen, per Investigator or medical supervisor dec
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary endpoint: Mean change from baseline in ADHD symptoms, as assessed by the AISRS after 6 weeks of treatment. The AISRS total score consists of 18 items from the original Attention- Deficit/Hyperactivity Disorder - Rating Scale (ADHD-RS), which were derived based on DSM-5 criteria for ADHD. The ADHD-RS includes 9 items that address symptoms of inattention, and 9 items that address symptoms of impulsivity and hyperactivity. Each item is rated from 0 to 3. The AISRS total score can range from 0 to 54. A higher score corresponds to a worse severity of ADHD. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints: ADHD-related endpoints: * key secondary endpoint: change from baseline in AISRS after 1 week (2 doses) of treatment. * occurrence of patients who experience at least a 1-point decrease in the CGI-S * change from baseline in CGI-S after 1 week (2 doses) of treatment and after 6 weeks of treatment * change from baseline in patient self-assessment by the Adult ADHD Self-Report Scale (ASRS) and Connors* Adult ADHD Rating Scale (CAARS). Safety Endpoints * vital signs (supine blood pressure, heart rate) * 12-lead safety ECG * psychological and/or physiological adverse events * Safety laboratory evaluation and Urine pregnancy testing * Columbia-Suicide Severity Rating Scale (C-SSRS) | — |
