Open-label, Decentralized Study of SPN-812 (Qelbree®) in Adults With ADHD and Mood Symptoms

Study Overview
=================
Brief Summary
-----------------
Open label, flexible dose, decentralized clinical trial evaluating the efficacy and safety of SPN-812 in adults with ADHD and mood symptoms.

Detailed Description
-----------------
This is a Phase IV, open-label, flexible dose, decentralized clinical trial to evaluate the efficacy and safety of SPN-812 in adults with ADHD and mood symptoms. Adults 18 years and older with ADHD will be recruited, consented and screened for eligibility. Following the Screening Period (up to 4 weeks), eligible participants will be treated with Study medication for up to 14 weeks (Treatment Period). The total study duration is approximately 18 weeks, and there are up to 6 virtual study visits (or Televisits). All Televisits are conducted via an application downloaded to participant's mobile phone. There are up to 2 Televisits during the Screening period and 3 Televisits during the Treatment period. Subjects initiate SPN-812 dosing at 200 mg once daily during first week, and then titrate up to 400mg once daily during the second week. At the Investigator's discretion, based subject's clinical response and tolerability, the dose of SPN-812 can be increased or decreased to optimal dose within the range between 200 and 600 mg once daily during the remaining Treatment period. Participants will answer questions during structured clinical interviews with an investigator during Televisits and complete additional questionnaires and scales via the mobile app.

Is a non-pregnant Female of Childbearing Potential (FOCP) who is not seeking fertility treatment during the study and agrees to use one of the following acceptable birth control methods beginning 14 days prior to the first dose of study medication, throughout the study while taking study medication, and for 7 days following the last dose of study medication: i. Hormonal contraceptive; ii.Barrier method: simultaneous use of male condom and diaphragm or cervical cap with spermicidal foam/gel/film/cream/suppository. Has had bilateral tubal ligation, hysterectomy, bilateral oophorectomy (permanently sterilized) at least 6 months prior to providing informed consent. If potential subject is a biological male, one of the following must be met: Is capable of having children and agrees to use 2 methods of contraception beginning 14 days prior to the first dose of study medication, throughout the study while taking study medication, and for 7 days following the last dose of study medication. Has had sterilization surgery (permanently sterilized) at least 6 months prior to providing informed consent. Owns a functioning smartphone device, has access to an internet connection (Wi-Fi or data plan), is willing to download and use the study mobile app throughout the study, and is willing to have visual telemedicine appointments (televisits) at times designated in the study protocol. Exclusion Criteria: A participant who meets any of the following criteria will be excluded from participation in the study: Has a history of substance use disorder (alcohol, opioids, etc.) within the last 6 months prior to providing informed consent with exception of nicotine and cannabis. Is currently taking or has taken Qelbree for treatment of ADHD in the last 3 months or is currently taking another non-stimulant medication for treatment of ADHD, like atomoxetine (Strattera), Clonidine (Catapres, Kapvay) or Guanfacine (Tenex, Intuniv). Stimulant medications for ADHD and most medications for mood symptoms (symptoms of depression and/or anxiety) are allowed. Is taking a prohibited concomitant medication per the Qelbree prescribing information. Is a FOCP who is pregnant, nursing, sexually active with a male partner and not willing to use one of the acceptable birth control methods throughout the study and/or is seeking fertility treatment. Has a history of moderate or severe head trauma or other neurological disorder or systemic medical disease that, in the Investigator's opinion, is likely to affect central nervous system functioning. This would include participants with: A current diagnosis of a major neurological disorder; or Seizures, seizure disorder or seizure-like events; or a history of seizure disorder within the immediate family (siblings, parents); or Encephalopathy Has attempted suicide within the 6 months prior to the C-SSRS assessment at Screening, or is at significant risk of suicide, either in the opinion of the Investigator or defined as a yes to suicidal ideation questions 4 or 5 or answering yes to suicidal behavior on the C-SSRS within the 6 months prior to the C-SSRS assessment at Screening. Is currently participating in another clinical trial or has participated in a clinical trial within the 60 days prior to providing informed consent. Has any history of schizophrenia, schizoaffective disorder, or bipolar disorder, or has any other psychiatric disorders in the investigator's clinical judgement would interfere with their ability to participate in the study. Has any unstable, clinically significant cardiovascular condition that in the investigator's clinical judgement would preclude their participating in the study. Has any disease or taking any medication that could, in the Investigator's opinion, interfere with the assessments of safety, tolerability, or efficacy, or interfere with study conduct or interpretation of results. History of unexplained loss of consciousness, unexplained syncope, unexplained irregular heartbeat or palpitations or near drowning with hospital admission. In the Investigator's opinion, is unlikely to comply with the protocol or is unsuitable for any other reason.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline in the Adult ADHD Investigator Symptom Rating Scale (AISRS) Total score by visit. | The Adult ADHD Investigator Symptom Rating Scale (AISRS) is an ADHD-specific rating scale designed and validated to assess current ADHD symptomatology in adults. The AISRS consists of 18 items that directly correspond to the 18 symptoms of ADHD per the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The scale is subdivided into two subscales: Inattention (IA; 9 items) and Hyperactivity/Impulsivity (HI; 9 items). The clinician/investigator rates the subject on each item using a 4-point scale, where 0=none, 1=mild, 2=moderate, and 3=severe. The sum of the ratings of all 18 items yields the raw Total score (range: 0-54; the higher the Total score, the more severe the ADHD symptoms). Post-baseline raw Total scores are converted to a change from baseline Total score. A lower change from baseline Total Score (<0) represents a better outcome. | Baseline and Week 4, 9, and 14 |

The clinician/investigator rates the subject on each item using a 4-point scale, where 0=none, 1=mild, 2=moderate, and 3=severe. The sum of the ratings of the respective 9 items yields the raw score for each subscale (range: 0-27; the higher the Subscale score, the more severe the symptoms). Post-baseline raw Subscale scores are converted to a change from baseline Subscale score. A lower change from baseline Subscale Score (<0) represents a better outcome. | Baseline and Week 4, 9, and 14 |
