Importance: Selective serotonin reuptake inhibitors (SSRIs) and cognitive behavioral therapy are the first-line treatments for pediatric obsessive-compulsive disorder (OCD) populations. Due to their limited effectiveness, additional treatment options are needed. A new potential pharmacological medication treatment avenue for OCD is intravenous (IV) ketamine. Objective: This study aimed to establish the feasibility, acceptability, and preliminary efficacy of an IV ketamine infusion for the treatment of refractory OCD in adolescents. Design: In this clinical pilot trial, every participant received IV ketamine infusion. Symptom severity and side effects were assessed daily for 2 weeks following the infusion. Setting: Study procedures were conducted at the New York State Psychiatric Institute, including a combination of in-person visits and phone calls. Participants: Five adolescents with OCD (age M, SD: 16.6 ± 1.5), who had previously failed trials of first-line treatments were enrolled. Intervention: All participants received an IV infusion of 0.5 mg/kg ketamine hydrochloride. Main Outcomes and Measures: A multimethod approach was applied, including physiological, self-report, and clinician-rated measures. To assess feasibility and acceptability, vital signs, electrocardiogram suicidality, self-reported adverse events, and dissociative symptoms were obtained. Obsessive-compulsive (OC) (Yale-Brown Obsessive Compulsive Challenge Scale, CY-BOCS) and depressive symptom severity, as well as global clinical impression, were assessed to investigate preliminary efficacy. Results: The mean (SD) pre- and 14-day posttreatment CY-BOCS were 29 (5.5) and 26.2 (5.6). There were no incidents of abnormal vital signs, mortality, or suicidal ideation in the 2 weeks following the infusion. All participants experienced mild dissociative symptoms in the 40 minutes after the IV ketamine infusion. Descriptively, OC symptom severity decreased immediately after the infusion but was not maintained over the course of the study. Conclusions and Clinical Significance: Ketamine is well-tolerated in adolescents with OCD and therefore appropriate for further efficacy testing. Trial Registration: ClinicalTrials.gov Identifier: NCT02422290.

Introduction: Viloxazine extended-release (VLX-ER) is effective as monotherapy for attention-deficit/hyperactivity disorder (ADHD), and is often tried as an add-on treatment when psychostimulant therapy fails to provide an adequate treatment response. This phase 4, open-label study evaluated safety, tolerability, and efficacy of VLX-ER with optimized psychostimulants in pediatric participants with ADHD. Morning versus evening VLX-ER use was also evaluated. Methods: Children and adolescents (6-17 years) experiencing inadequate psychostimulant response (investigator-assessed ADHD Rating Scale-5 [ADHD-RS-5] score ≥24 and Clinical Global Impression-Severity of Illness [CGI-S] scores ≥3) during a 4-week screening period received flexibly-dosed VLX-ER, taken once daily in the morning (weeks 14) or evening (weeks 5-8), concomitantly with a psychostimulant. Safety (primary outcome) and efficacy were evaluated relative to baseline. Results: Fifty-six participants (26 children; 30 adolescents) enrolled, and 48 (85.7%) completed the study. Combination therapy was well tolerated, with only two participants (3.6%) withdrawing due to adverse events (AEs). The most commonly reported AEs were headache (17.9%), decreased appetite (12.5%), and upper respiratory tract infection (10.7%). Mean ± standard deviation investigator-assessed ADHD-RS-5 scores (baseline: 37.2 ± 8.4) improved progressively by -13.5 ± 9.7 points at week 4 and -18.2 ± 10.0 points at week 8 (p < 0.0001 each). Likewise, CGI-S scores (baseline: 4.4 ± 0.6) improved by -0.9 ± 0.9 at week 4 and -1.4 ± 1.1 at week 8 (p < 0.0001 each). Parent-assessed scales, including ratings of morning and evening ADHD behaviors and sleep disturbances, showed significant improvement relative to baseline regardless of morning (week 4) or evening (week 8) VLX-ER dosing. Conclusion: Combined treatment with VLX-ER and psychostimulant therapy showed acceptable safety and tolerability, with improvement in morning and evening ADHD behaviors and sleep disturbances relative to stimulant monotherapy. Timing of VLX-ER administration (morning or evening) did not appear to affect safety, drug response, or sleep improvement.

Objective: To provide an evidence-based review of the Comprehensive Behavioral Intervention for Tic (CBIT) disorders. Results: For close to a century, behavioral interventions for managing tics associated with Tourette and other tic disorders (TDs) were incorrectly considered ineffective and dangerous by the professional community, due, in large part, to unfounded fears that efforts to suppress tics would lead to a host of negative psychological, and even physical, outcomes (e.g., symptom substitution, tic rebound). Spurred by a growing body of research to the contrary, the Comprehensive Behavioral Treatment for Tics (CBIT) was developed to provide a tolerable and effective nonpharmacological treatment option, alone or in combination with medication, for youth and adults with tics associated with Tourette or other TDs. CBIT combines two evidence-based practices, habit reversal training (HRT) to address the urge-tic relationship and a functional intervention to identify and neutralize tic-related environmental factors. Based on positive findings from two large-scale randomized controlled trials that involved a total of 248 8-69-year olds with Tourette or chronic TD, CBIT has been designated as a first-line treatment, when available, for treating tics by the American Academy of Neurology and the European and Canadian medical academies. Conclusions: CBIT has demonstrated acute and durable efficacy when delivered alone or in combination with medication, in person, or via telehealth, and in the presence or absence of common comorbid conditions. Additional research is needed to develop and test treatment guidelines for the use of CBIT in combination with pharmacologic, neuromodulatory, and other intervention modalities.

Objectives: There are currently no long-acting injectable antipsychotics (LAIAs) that are approved by the Food and Drug Administration for use in child and adolescent patients, however these agents are used off-label for the treatment of various psychiatric disorders. This study aims to describe the initiation and maintenance dosing strategies of LAIAs in child and adolescent psychiatry inpatients. Methods: This was a single-site retrospective chart review of patients less than 18 years of age initiated on an LAIA during an acute psychiatric hospitalization between October 1, 2015, and October 31, 2022. Patient demographics and hospital encounter information were collected and analyzed using descriptive statistics. Results: Of the 6402 unique pediatric patients discharged from the acute psychiatric hospital within the specified timeframe, 45 (0.7%) were newly initiated on an LAIA. The average age was 15.6 years (range 10-17), with a greater proportion of male (n = 26, 57.8%) and Black or African American (n = 27, 60%) patients. The LAIA agents prescribed included paliperidone palmitate (n = 21, 46.7%), aripiprazole monohydrate (n = 15, 33.3%), aripiprazole lauroxil (n = 7, 15.6%), haloperidol decanoate (n = 1, 2.2%), and risperidone microspheres (n = 1, 2.2%). Primary diagnosis via International Classification of Diseases-10 code at discharge included schizophrenia spectrum and other psychotic disorders (n = 19, 42.2%); bipolar disorder (n = 14, 31.1%); disruptive, impulse control, and conduct disorders (n = 6, 13.3%); autistic disorder (n = 5, 11.1%); and attention-deficit/hyperactivity disorder (n = 1, 2.2%). Seventeen patients (37.8%) received a loading dose regimen and/or a maintenance dose regimen that differed from adult package-insert dosing. The mean length of stay was 23.7 days, and 14 patients (31.1%) were readmitted to the psychiatric hospital within 6 months of discharge. The mean number of days to readmission was 71.9 days. Conclusions: This retrospective study is the first to focus on LAIA initiation and maintenance dosing strategies of multiple agents in both a child and adolescent patient population. Further research is required to evaluate the impact of LAIAs on clinical outcomes in this patient population.

Objectives: Long-acting injectable (LAI) antipsychotic medications are being prescribed to children and adolescents along a broad age range from 2 to 17 years old. However, there is no U.S. Food and Drug Administration (FDA) approved indication for the use of any LAI in a pediatric population. The goal of this article is to perform a systematic literature review regarding the use of LAIs in a pediatric population, to obtain pediatric LAI safety data, and to survey prescriber attitudes regarding LAI use in youth. Methods: A search for relevant articles between June 1986 and June 2021 was conducted. Safety data were obtained from FDA MedWatch postmarketing adverse event reports regarding LAI use in children and adolescents. A survey of practicing Child and Adolescent Psychiatrists in Wisconsin was done regarding the use of LAIs in youth. Results: The predominant reasons for LAI use in youth were illness severity and treatment noncompliance. Twenty-six of 30 identified studies and reports favored LAI use in youth, but were of low to very low quality. Overall, 587 FDA MedWatch reports between June 1986 and June 2021 were identified. Most adverse events occurred in modest numbers. Extrapyramidal symptoms accounted for 18% of all MedWatch reports, neuroleptic malignant syndrome accounted for 3% of all reports, and deaths accounted for 2% of all reports. The concern for safety was reflected in prescriber survey results along with a recognition that LAIs can be helpful to target severe psychiatric symptoms and address treatment noncompliance. Conclusions: No randomized controlled studies were found. Identified published studies and reports were of low to very low quality. However, it appeared reasonable that the use of LAIs in a select group of pediatric patients can be helpful to target severe psychiatric symptoms and to enhance treatment compliance.
