Abstract:Study Objective:SPN-812 (extended-release viloxazine) is a structurally distinct, bicyclic, Serotonin Norepinephrine Modulating Agent (SNMA) in development as a treatment for attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. This Phase 3, randomized, double-blind study (P303) evaluated the efficacy and safety of once-daily SPN-812 at doses of 200 and 400 mg compared to placebo in children ages 6-11yrs with ADHD.Method:Inclusion criteria required subjects have a confirmed Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) ADHD diagnosis, ADHD-Rating Scale-5 (ADHD-RS-5) score ≥28, Clinical Global Impression-Severity score ≥4, and be free of ADHD medication ≥1 week before randomization. Subjects were enrolled at 31 study sites in the United States. Subjects (N=313) were randomized 1:1:1 to placebo:200 mg SPN-812:400 mg SPN-812. Treatment included up to 3 weeks of titration and 5 weeks of maintenance (intent-to-treat population: N=301; placebo=97, 200 mg=107, 400 mg=97). The primary efficacy endpoint was change from baseline (CFB) at end of study (EOS) in ADHD-RS-5 total score. Key secondary endpoints included Clinical Global Impression-Improvement (CGI-I) score at EOS, and CFB at EOS in Conners 3-Parent Short Form (Conners 3-PS) Composite T-score and in Weiss Functional Impairment Rating Scale-Parent Form (WFIRS-P) total average score. Safety assessments included adverse events (AEs) among other measures.Results:Compared to placebo, a significantly greater improvement in ADHD-RS-5 total score was observed in the 200 mg and 400 mg SPN-812 treatment group at EOS (p=0.0038, p=0.0063; respectively). Significant improvement in CGI-I score at EOS for both 200 mg and 400 mg SPN-812 was also observed (p=0.0028, p=0.0099; respectively). Significant improvement was observed for the 200 mg SPN-812 dose compared to placebo in the Conners 3-PS Composite T-score (p=0.0064), but not for the 400 mg dose (p=0.0917). No significant improvement was observed in either dose group in the WFIRS-P total average score (p=0.0651, p=0.1680; respectively). The most common (≥5%) treatment-related AEs were somnolence, decreased appetite, fatigue, headache, and upper abdominal pain.Conclusions:In this study, SPN-812 met the primary objective for both the 200 and 400 mg doses and the key secondary objective (CGI-I) for both the 200 and 400 mg doses with statistical significance. A second key secondary objective (Conners 3-PS) for the 200 mg dose was also met. AE-related dropouts were ≤5%, indicating SPN-812 treatment was well tolerated.This study is an encore of a poster presentation at the 2019 Annual Meeting of the American Academy of Child and Adolescent Psychiatry (AACAP).Funding Acknowledgements:This research was funded by Supernus Pharmaceuticals, Inc., Rockville, MD.

Abstract:Study Objective:Tardive dyskinesia (TD), a persistent and potentially disabling movement disorder, is associated with prolonged exposure to antipsychotics and other dopamine receptor blocking agents. Valbenazine (VBZ) is a novel and highly selective vesicular monoamine transporter 2 (VMAT2) inhibitor approved for the treatment of TD in adults. Using data from two long-term phase 3 studies (KINECT 3 [K3], NCT02274558; KINECT 4 [K4], NCT02405091) and a rollover study (1506, NCT02736955), the long-term outcomes of once-daily VBZ on TD were examined in participants who received 40mg or had a dose reduction from 80 to 40mg.Methods:The effects of VBZ 40mg (as well as VBZ 80mg) were evaluated in the following studies: the pivotal K3 study (6 weeks double-blind, placebo controlled), the extension phase of K3 (42 additional weeks of VBZ, 4 week discontinuation), and the open-label K4 study (48 weeks of VBZ, 4 week discontinuation). Completers from K3 extension and K4 were invited to participate in 1506 (up to 72 additional weeks of VBZ or until commercial availability of VBZ). Few participants reached Week 60 (n=4) or Week 72 (n=0) in the 1506 study before termination. Analyses focused on VBZ 40mg in two populations: pooled K3/K4 (participants who received VBZ 40mg throughout K3 or K4 or who had a dose reduction [80/40mg] during K3 or K4); and 1506 (participants who received VBZ 40mg from beginning of K3 or K4 to last visit in 1506 or who had a dose reduction [80/40mg] at any time). Outcomes for the K3/K4 population included mean change from baseline (CFB) in Abnormal Involuntary Movement Scale (AIMS) total score (sum of items 1-7) and AIMS response (≥50% total score improvement from baseline) at Week 48 of K3 or K4. Outcomes for the 1506 population included a Clinical Global Impression of Severity-Tardive Dyskinesia (CGIS-TD) score ≤2 (“normal, not at all ill” or “borderline ill”).Results:In the K3/K4 population, AIMS CFB to Week 48 indicated mean TD improvements in participants who received 40mg continuously (40mg, -5.7 [n=54]) and in those who had a dose reduction to 40mg (80/40mg, -6.2 [n=13]). In addition, a majority of these participants had an AIMS response after 48 weeks of treatment (40mg, 53.7%; 80/40mg, 53.8%). In the 1506 population, the percentage of participants who had a CGIS-TD score ≤2 (rating of “normal, not at all ill” or “borderline ill”) at Week 12 was 63.6% (7/11) in the 40mg group and 30.8% (4/13) in the 80/40mg group. Data from Weeks 24 to 60 of 1506 were limited by the small sample sizes (<10 participants each in 40mg or 80/40mg group at each of these visits).Conclusions:Based on these analyses and results from published studies, VBZ 40mg may be an effective long-term option for some TD patients. Dose reductions from 80 to 40mg, if necessary, did not appear to compromise long-term benefit.Funding Acknowledgements:This study was sponsored by Neurocrine Biosciences, Inc.
131 A Marionettist Pulling My Strings: A Case of Buprenorphine-induced Chorea
Authors: Patel Dev , Gandhi Ishandeep , Malek Faisal , Olechowski Camille , Hirsch Alan R. 
Published: April 2020

Abstract:Introduction:Choreaform movements provoked by opiates is an infrequent adverse event. Buprenorphine induction of chorea has not heretofore been described. Such a case is presented.METHOD:Case Study: A 38-year-old female presented with a decade long history of alcohol, cocaine, benzodiazepine, and heroin abuse. The patient was insufflating 1.5 grams of heroin daily. On presentation, she was actively withdrawing, scoring 17 on the Clinical Opioid Withdrawal Scale. Urine toxicology screening was positive for opiates, cocaine, and cannabinoids. Buprenorphine 4 mg sublingual was initiated. Within one hour, she observed, “My legs were moving uncontrollably as if I was a marionette.” These dance-like movements were isolated to both legs and gradually resolved after discontinuation of buprenorphine: most of the movements manifested in the first 8 hours, and dissipated over the next 2 days. She did have similar movements after treatment with quetiapine during a previous hospitalization, years earlier.RESULTS:Abnormalities in physical examination: General: goiter, bilateral palmar erythema. Neurological examination: Cranial Nerve (CN) Examination: CN I: Alcohol Sniff Test: 2 (anosmia). Motor Examination: Drift testing: mild right pronator drift. Reflexes: 3+ bilateral lower extremities. Neuropsychiatric Examination: Clock Drawing Test: 3 (abnormal). Animal Fluency Test: 18 (normal). Go-No-Go Test 6/6 (normal).DISCUSSION:Buprenorphine induced chorea could be a result of partial mu-opioid agonism, or kappa and delta receptor antagonism (Burke, 2018; Cowan, 1977). Mu-opioid receptor activation causes increased dopamine turnover in the nigrostriatum, which is responsible for locomotor sensitization (Campos-Jurado, 2017). With the addition of mu-opioid receptor modulation of dopamine release, kappa-opioid receptor alters various neurotransmitters in the basal ganglia, potentiating hyperkinetic movements. Buprenorphine’s choreiformogenic action may be due to kappa-opioid receptors ability to augment neurotransmission in the striatum (Escobar, 2017; Bonnet, 1998). The combination of simultaneous activity of these three opioid receptors may cause chorea, since they act to modulate dopamine, glutamate, and GABA in the direct and indirect pathways within the basal ganglia (Abin, 1989; Cui, 2013; Allouche, 2014; Trifilieff, 2013). This patient’s history of heroin and cocaine use may have caused supersensitization of dopamine receptors (Memo, 1981), provoking hyperkinesia. Involvement of substance-induced sensitization with concurrent kappa-opioid receptor neurotransmitter augmentation in direct and indirect pathways in the basal ganglia may have primed our patient to the development of chorea after buprenorphine administration. Further investigation for the presence of extrapyramidal movements in those undergoing buprenorphine treatment is warranted.
132 Treating Comorbid Childhood Bipolar Disorder and ADHD
Authors: Nemeth Darlyne G. , Mckenzie Chustz Kayla 
Published: April 2020

Abstract:Objectives:According to Nemeth et al. (2011), pediatric mania is difficult to distinguish from childhood hyperactivity. Both share 3 common symptoms: distractibility, motoric hyperactivity, and talkativeness (Biederman, 2000). Oftentimes, children are referred from their pediatrician due to a lack of appropriate response to stimulant medication. Pediatricians have learned that merely raising the dose or changing the stimulant does not work. A thorough neuropsychological evaluation often reveals Bipolar Mania. They may have comorbid Bipolar Disorder and ADHD. This poster paper will examine measures that can assist in this important differential diagnosis as well as offer treatment options, including medication management.Methods:This case study includes three pediatric patients diagnosed with Childhood Bipolar Disorder and ADHD. A comprehensive psychoeducational assessment was conducted for each of the patients, which resulted in this comorbid diagnosis.Results:One of the most helpful measures was the TOVA. When a child’s attention and impulsivity scores are normal, and response time and variability scores are abnormal, both on and off medication, that is an indication of a mood disorder (Nemeth et al., 2007). These children also performed poorly on measures of processing speed, and verbal learning and interference tasks (Henin et al., 2007). Measures of affect and personality were important diagnostically. A combination of Amantadine and either Clonidine HCL ER or Propranolol, as prescribed by a medical psychologist, were found to be effective in controlling the symptoms of this comorbid diagnosis.Conclusions:An evaluation of children’s intellectual, attentional, behavioral, mood, and personality functioning is crucial for a differential diagnosis. In cases of comorbidity, ADHD and Childhood Bipolar Disorder, the sooner the child is on appropriate medications, the better. When just the surface diagnosis of ADHD is medicated, the outcome is often problematic. There may be a poor response to treatment and a higher rate of suicide.

Disclaimer:The views expressed in this abstract are those of the authors and do not reflect the official policy of the Department of Army/Navy/Air Force, Department of Defense, or U.S. Government.Background:Alzheimer s disease (AD) is a progressive neurodegenerative disease leading to cognitive decline and eventually death. Degradation of cortical neuroplasticity is thought to be a major catalyst of AD-related cognitive decline. Repetitive transcranial magnetic stimulation (rTMS), which uses pulsed magnetism to stimulate neurons, increases cortical plasticity and induces long-lasting neuroplastic changes. Patients have benefited from rTMS to treat AD, especially when done in conjunction with cognitive training exercises. This case report presents a 31-year-old male who tested positive for an autosomal dominant mutation implicated in early-onset AD. rTMS and cognitive training were employed to assist in the delay of early-onset AD manifestation in two cycles.Methods:Prior to each treatment cycle, the patient completed questionnaires and interviews designed to test his cognitive functioning; his spouse was interviewed to provide a third-party assessment of his functioning. Following pre-treatment data collection, 30 daily rTMS/cognitive training sessions were completed in the first cycle and 35 daily rTMS/cognitive training sessions were completed in the second cycle. The bilateral dorsolateral prefrontal cortices each received 1,000 pulses (10 Hz, 110% SMT). Tolerability and side effect data were collected after each treatment. Immediately following rTMS, the patient played cognitive training games at our Brain Fitness Center. All pre-treatment assessments were repeated after completion of the 30 sessions in the first cycle and the 35 sessions in the second cycle for comparison of pre- to post-treatment cognitive functionality.Results:Pre-treatment testing indicated the patient was asymptomatic before each cycle. The patient completed 30 daily rTMS sessions in the first cycle and 35 daily rTMS sessions in the second cycle. Tolerability/side effect data showed he tolerated treatment well and experienced only minor pain. The patient also completed 30 cognitive training sessions in the first cycle and 35 cognitive training sessions in the second cycle and showed moderate improvement across all cognitive domains. Post-treatment assessments indicated no change in functioning except to note the patient s improved sleep. A third treatment cycle is scheduled to begin in February 2020.Conclusions:This case report supports rTMS paired with cognitive training to be a safe and tolerable treatment for early-onset AD. However, more treatment cycles must be completed before conclusions about its efficacy can be determined.
166 Post Market Rate of Seizures During TMS Treatment with NeuroStar® System Appears to Be Lower than Previously Estimated
Authors: Janicak Paul , Heart Karen , McGugan Bridget 
Published: April 2020

Abstract:Objective: NeuroStar® Advanced Therapy System is a transcranial magnetic stimulation (TMS) device with FDA-clearance for the treatment of Major Depressive Disorder (MDD) in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode. With TMS, magnetic pulses are transmitted into the brain. Though the exact mechanism of action is unknown, it is postulated that resulting neuronal depolarization and changes in brain functional activity may be associated with various physiologic changes that lead to relief of depression in the indicated population. The type of magnetic field generated with TMS is not intended to induce a seizure during therapeutic use, but unintentional seizures have been reported during TMS treatment.No seizures were reported with the use of the NeuroStar® system in clinical trials conducted prior to FDA clearance. The estimated risk of seizure in the NeuroStar® label is approximately 1 in 30,000 treatments or 1 in 1,000 patients. Since introduction of the NeuroStar® system into clinical practice, the rate at which seizures have been reported is even lower.Methods:We conducted a review of literature that named the NeuroStar® Advanced Therapy System as the device used for TMS treatment and reviewed all seizure events reported to Neuronetics, Inc., directly or through FDA MedWatch through June 30, 2019. Articles reporting seizures in subjects with epilepsy during TMS treatment were excluded.Results:Previous comprehensive reviews of seizures induced by treatment with any TMS device by Wasserman et al. (1998) and Rossi et al. (2009) revealed that the rate of seizures is low. Many subjects that developed seizures during TMS had either received stimulation at parameters beyond current recommendations or had been predisposed to develop seizures in some way. Some of the events reported as seizures may, in fact, have been non-epileptic events.Our literature review and analysis of seizures reported to Neuronetics, Inc. revealed that the rate of seizures during TMS treatment with the NeuroStar® appears to be lower than the rate that is published in the NeuroStar® Advanced Therapy prescribing information.Conclusions:Seizures that take place during TMS treatment with the NeuroStar® system are rare. The rate of seizures reported directly to Neuronetics, Inc. is lower than that included in the NeuroStar® prescribing information. Our literature review validated seizures during TMS treatment with the NeuroStar® system reported in published literature have described either non-epileptic events (syncope) or occurred with risk factors for seizure induction, such as other predisposing clinical factors or treatment parameters outside the guideline recommend “safe” ranges.Funding Acknowledgements:Neuronetics, Inc.

Published: April 2020

Abstract:Objective:Evaluate efficacy and safety of a 2-month dose of aripiprazole lauroxil (AL) with a 1-day initiation regimen during hospitalization for an acute exacerbation of schizophrenia.Methods:In the phase 3b double-blind ALPINE study, adults with schizophrenia were randomized to AL (AL NanoCrystal® Dispersion + oral aripiprazole 30 mg day 1; AL 1064 mg day 8 and every 8 weeks) or paliperidone palmitate (PP 234 mg day 1; PP 156 mg day 8 and every 4 weeks). Patients were discharged after 2 weeks of hospitalization and followed through week 25. Primary endpoint was within-group changes in PANSS total score from baseline to week 4 (observed cases). Secondary analyses included within-group changes at weeks 9 and 25 (observed) and between-group comparisons at weeks 4, 9, and 25 (MMRM). Adverse events (AEs) were monitored throughout the study.Results:200 patients were randomized (AL, n=99; PP, n=101); 56.6% and 42.6%, respectively, completed the study. Within-group changes from baseline in PANSS were −17.4 for AL and −20.1 for PP at week 4 (both groups, P<0.001) and continued to decline at weeks 9 (AL, −19.8; PP, −22.5) and 25 (AL, −23.3; PP, −21.7). The change in PANSS over time was similar between groups. AEs occurring in ≥10% of patients in either group were injection site pain (AL, 17.2%; PP, 24.8%), akathisia (AL, 9.1%; PP, 10.9%), and weight increased (AL, 9.1%; PP, 16.8%).Conclusions:AL and PP were effective and well-tolerated for initiating treatment of schizophrenia in the hospital and continuing in the outpatient setting.Funding Acknowledgements:This study was funded by Alkermes, Inc.
168 Effect of Dasotraline on Body Weight in Patients with Binge-Eating Disorder
Authors: Citrome Leslie , Goldman Robert , Tsai Joyce , Deng Ling , Grinnell Todd , Pikalov Andrei 
Published: April 2020

Abstract:Background:Binge-eating disorder (BED) is associated with obesity (BMI ≥30) in approximately 40-45% of patients. Dasotraline is a long-acting dopamine/norepinephrine reuptake inhibitor with a PK profile characterized by slow absorption and an elimination half-life of 47-77 hours, permitting once-daily dosing. In a recent placebo-controlled, flexible-dose study, dasotraline demonstrated significant efficacy in patients with BED. We now report an analysis from this study of the effect of dasotraline on body weight.Method:Patients with moderate-to-severe BED, based on DSM-5 criteria, were randomized to 12 weeks of double-blind flexible-dose treatment with dasotraline (4-8 mg/d) vs. placebo. The primary efficacy outcome was number of binge-eating days/week. Mean change in body weight at Week 12 (assessed as a safety outcome) was analyzed by baseline body mass index (BMI, kg/m2) category. Inferential statistics were not performed.Results:The safety population consisted of 317 patients (female, 84%; mean age, 38.2 years; mean weight, 97.3 kg). At baseline, the proportions of patients in each BMI category were as follows: normal (<25 kg/m2: 5.7%), overweight (25 to <30 kg/m2: 18.3%), obesity class I (30 to <35 kg/m2: 24.9%), class II (35 to <40 kg/m2: 29.3%), and class III (≥40 kg/m2: 21.8%). For the overall patient sample, treatment with dasotraline significantly reduced the number of binge-eating days per week vs. placebo (-3.74 vs. -2.75; P<0.0001; effect size = 0.74). Mean changes at Week 12 in weight (kg) for completers treated with dasotraline vs. placebo, by baseline BMI category, were as follows: normal weight (-4.6 vs. -0.2), overweight (-5.8 vs. +1.3), and combined obesity classes I-III (-6.2 vs. +0.3). Among obese patients (Class I-III, combined) treated with dasotraline, weight reduction (≥5%) was observed in 45.3% of patients (vs. 4.1% on placebo); and weight reduction ≥10% in approximately 13.7% of patients (vs. none on placebo). Weight-related adverse events, for dasotraline vs. placebo, consisted of decreased appetite (19.7% vs. 6.9%), decreased weight (12.1% vs. 0%), and increased weight (0.6% vs. 1.3%).Conclusion:Among patients completing 12 weeks of treatment with dasotraline, weight reduction ≥5% was observed in 45% of obese patients with a BMI ≥30. The most frequent weight-related adverse event was decreased appetite, reported in approximately one in five patients treated with dasotraline.Clinicaltrials.gov number: NCT02564588Funding Acknowledgements:Supported by funding from Sunovion Pharmaceuticals Inc.
