Clinical Trial Summary

This open label, flexible-dose study evaluating the safety and efficacy of SPN-812 administered with psychostimulants in children and adolescents (6 to 17 years of age) with Attention-Deficit/Hyperactivity Disorder (ADHD).


Description:

This is an open-label, multicenter, flexible-dose, safety study of SPN-812 in pediatric patients (6-17 years of age) diagnosed with ADHD, when administered with a FDA-approved medication (psychostimulant) in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in pediatric subjects. Participants will be screened for eligibility for up to 4 weeks, and he/she will continue to take their prescribed psychostimulant ADHD medication during that time. Following the screening period, eligible subjects will receive SPN-812 with their current psychostimulant treatment for ADHD for 8 weeks. For the first 4 weeks of treatment subjects will take SPN-812 dose in the morning (AM dosing), and for the last 4 weeks of treatment, subjects will take SPN-812 dose in the evening (PM dosing). The total duration of the study between the screening visit and the end of the treatment period/end of study (EOS) visit is up to 12 weeks.

Outcome

Type Measure Description Time frame Safety issue
Primary Incidence of Adverse Events During 8 Weeks of Adjunct SPN-812 Treatment The percent of subjects who took at least one dose of SPN-812 and reported at least one adverse event during 8 weeks of adjunct SPN-812 Treatment. The percent is calculated by dividing "the number of subjects who reported at least one Adverse Event (n)" by "the number of subjects in the Safety Population (N)" and then multiplying the product by 100. The higher the percent, the higher the incidence. Weeks 1-8
Secondary Incidence of Adverse Events During Adjunctive SPN-812 Treatment During Weeks 1-4 (SPN-812 Dosed in Morning Hours [AM Dosing]) and During Weeks 5-8 (SPN-812 Dosed in Evening Hours [PM Dosing]) The percent of subjects who reported at least one adverse event during adjunctive SPN-812 Treatment during Weeks 1-4 (SPN-812 dosed in morning hours [AM Dosing]) and during Weeks 5-8 (SPN-812 dosed in evening hours [PM Dosing]). The percent is calculated by dividing "the number of subjects who reported at least one Adverse Event (n) during Weeks 1-4 or Weeks 5-8" by "the number of subjects analyzed during Weeks 1-4 or Weeks 5-8" (subjects who took at least once dose of SPN-812 during Weeks 1-4 or Weeks 5-8), respectively and then multiplying the product of each by 100. The higher the percent, the higher the incidence. Weeks 1-4 and Weeks 5-8
Secondary Change From Baseline in the Investigator-rated Attention-Deficit/Hyperactivity Disorder Rating Scale, 5th Edition (IR-ADHD-RS-5) Total Score at Week 4 (AM Dosing) and at Week 8 (PM Dosing) The Attention-Deficit/Hyperactivity Disorder Rating Scale, 5th Edition (ADHD-RS-5) is an ADHD-specific rating scale designed and validated to assess current ADHD symptomatology. The scale consists of 18 items that directly correspond to the 18 Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) symptoms of ADHD. Each item was rated by a trained investigator on a 4-point Likert-type scale from 0 (never or rarely) to 3 (very often). The sum of all 18 items yields the raw Total score (range: 0-54; the higher the score, the more severe the ADHD symptoms). Raw score is converted to a change from baseline (CFB) score. A CFB score <0 represents a better outcome. Baseline, Week 4, and Week 8
Secondary Change From Baseline in the Clinical Global Impression-Severity of Illness (CGI-S) Score at Week 4 (AM Dosing) and at Week 8 (PM Dosing) The Clinical Global Impression-Severity of Illness (CGI-S) scale is a single item clinician-rated assessment of the severity of the ADHD symptoms in relation to the clinician's total experience with patients with ADHD. The CGI-S is evaluated by the investigator on a 7-point scale, where 1 = Normal, not at all ill; 2 = Borderline mentally Ill; 3 = Mildly Ill; 4 = Moderately Ill; 5 = Markedly Ill; 6 = Severely Ill; and 7 = Among the most extremely ill patients; the higher the score, the more severe the ADHD symptoms. Raw score is converted to a change from baseline (CFB) score. A CFB score <0 represents a better outcome. Baseline, Week 4, and Week 8
Secondary Clinical Global Impression-Improvement (CGI-I) Score at Week 4 (AM Dosing) and at Week 8 (PM Dosing) The Clinical Global Impression-Improvement (CGI-I) is a single item, clinician-rated assessment of how much the clinician believes the subject's overall symptoms have changed (improved, worsened or no change) relative to subject's baseline state prior to the beginning of treatment. The CGI-I is evaluated by the investigator on a 7-point scale, where 1 = Very much improved, 2 = Much improved, 3 = Minimally improved, 4 = No change, 5 = Minimally worse, 6 = Much worse, and 7 = Very much worse. A CGI-I score <4 represents a better outcome. Week 4 and Week 8
