Abstract
INTRODUCTION In BIPARK-1 and BIPARK-2, addition of once-daily opicapone to levodopa/carbidopa significantly reduced daily "OFF"-time relative to placebo in adults with Parkinson's disease (PD) and motor fluctuations. Diary data from these studies were pooled and analyzed post hoc to characterize "OFF"-times around nighttime sleep and to explore the effects of opicapone 50 mg. METHODS "OFF" before sleep (OBS), "OFF during the nighttime sleep period" (ODNSP), early morning "OFF" (EMO), and duration of nighttime sleep and awake periods were analyzed descriptively at baseline. Mean changes from baseline to Week 14/15 (end of double-blind treatment) were analyzed using two-sided t-tests in participants with data for both visits. RESULTS At baseline, 88.3 % (454/514) of participants reported having OBS (34.0 %), ODNSP (17.1 %), or EMO (79.6 %). Those with ODNSP had substantially shorter mean duration of uninterrupted sleep (4.4 h) than the overall pooled population (7.1 h). At Week 14/15, mean decrease from baseline in ODNSP duration was significantly greater with opicapone than with placebo (-0.9 vs. -0.4 h, P < 0.05). In participants with ODNSP at baseline, the decrease in total time spent awake during the night-time sleep period was significantly greater with opicapone than with placebo (-1.0 vs. -0.4 h, P < 0.05), as was the reduction in percent time spent awake during the night-time sleep period (-12.8 % vs. -4.5 %, P < 0.05). CONCLUSION "OFF"-times around nighttime sleep were common in BIPARK-1 and BIPARK-2. Opicapone may improve sleep by decreasing the amount of time spent awake during the night in patients with PD who have night-time sleep period "OFF" episodes.

Abstract
BACKGROUND Tardive dyskinesia (TD), a movement disorder in which patients experience abnormal involuntary movements, can have profound negative impacts on physical, cognitive, and psychosocial functioning. The Abnormal Involuntary Movement Scale (AIMS), a clinician-rated outcome, is considered the gold standard for evaluating treatment efficacy in TD clinical trials. However, it provides little information about the impacts of uncontrolled movements from a patient perspective and can be cumbersome to administer in clinical settings. The Tardive Dyskinesia Impact Scale (TDIS) was developed as a patient-reported outcome measure to fulfill the need for a disease-specific impact assessment in TD. The objective of the present study was to develop and evaluate the psychometric properties of the TDIS to determine whether it is fit-for-purpose to measure TD impact. METHODS Data from qualitative studies and phase 3 trials of a VMAT2 inhibitor for the treatment of TD (KINECT3 and KINECT4) were used to determine the psychometric properties of the TDIS. Qualitative research included concept elicitation and cognitive debriefing interviews with TD patients and their caregivers in order to assess how well the TDIS captured key domains of TD impact. Quantitative analyses to examine the psychometric properties of the TDIS included assessing construct validity (factor structure, known groups, and predictive validity) and responsiveness to change. RESULTS Qualitative results showed that the TDIS captures the key TD impacts reported by patients and caregivers and that the TDIS was interpreted as intended and relevant to patients' experiences. Quantitative results found evidence of 2 underlying domains of the TDIS: physical and socioemotional (Comparative Fit Index > 0.9). Known groups and predictive validity indicated that, compared with the AIMS, the TDIS captures unique content (correlation between AIMS and TDIS = 0.2-0.28). The TDIS showed responsiveness to change in treatment, with TDIS scores improving over 48 weeks in the 2 phase 3 trials. CONCLUSIONS The TDIS captures relevant information about the impact of TD and is easily administered in a clinician's office or patient's home. It may be used longitudinally to show changes in TD burden over time. The TDIS complements the AIMS; using these assessments together provides a more holistic assessment of TD.

Abstract
INTRODUCTION Developmental and/or epileptic encephalopathy with spike-and-wave activation in sleep (D/EE-SWAS), also referred to as electrical status epilepticus during sleep (ESES) or epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS or EE-CSWS), is a spectrum of rare childhood epileptic encephalopathies that can lead to long-term cognitive impairment. Despite the importance of early diagnosis and intervention for D/EE-SWAS, there is a paucity of well-controlled clinical trial data to inform treatment, and no approved treatments are available. To assess correlations between diagnosis, treatment, and outcomes in D/EE-SWAS, we carried out a systematic review of the literature. METHODS In August 2020, we conducted comprehensive database searches using search terms including "electrical status epilepticus," "ESES," "CSWS," and "Landau-Kleffner syndrome." Two or more independent reviewers screened titles, abstracts, and full-text articles for those that met the following criteria: prospective studies (randomized controlled trials [RCTs] or open-label trials), retrospective studies (drug evaluations or observational studies/chart reviews), and case series with ≥ 10 participants. Both interventional and non-interventional studies were included (i.e., drug intervention was not an inclusion criterion). Articles published before 2012, review articles, animal studies, and studies of surgical or dietary interventions were excluded. Standardized data extraction templates were used to capture data on study design, patient characteristics, interventions, and outcomes from each of the selected publications. Study quality was assessed using the Cochrane Risk of Bias Tool for RCTs and the Newcastle-Ottawa Scale (NOS) or the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for retrospective, observational studies. RESULTS A total of 34 studies were included for full data extraction, most of which were uncontrolled and observational. Interpretation of study outcomes was limited by small study populations, variability in inclusion criteria, and inconsistency in methods of assessment and reporting of outcomes, which resulted in large heterogeneity in patients and their presenting symptoms. Despite these limitations, some patterns could be discerned. Several studies found that longer duration of ESES and younger age at onset were correlated with more severe language and cognitive deficits. In addition, several studies reported an association between improvement in cognitive outcomes and reduction in electroencephalogram (EEG) abnormalities and/or seizure frequency. In the 16 prospective or retrospective studies that evaluated drug treatments (e.g., antiseizure medications, corticosteroids, and high-dose diazepam), there was some improvement in EEG, seizure, and/or cognitive outcomes, although the specific outcomes and rates of improvement reported varied from study to study. CONCLUSION Long-term cognitive deficits remain common in D/EE-SWAS, and data gaps exist in the literature that preclude an evidence-based approach to managing this complex epilepsy indication. Early intervention with more effective medications is needed to optimize long-term outcomes. Sufficiently powered, randomized, double-blind, controlled trials with standardized methods and predefined primary and secondary outcomes are needed.

Abstract
Objective: To evaluate real-world treatment patterns for patients initiating benztropine and to understand treatment approaches in patients with drug-induced movement disorders from a health care provider perspective. Methods: A retrospective claims analysis was conducted among patients with evidence of benztropine initiation from January 2017 through March 2020 to assess treatment patterns and patient health care resource utilization. Subsequently, a 30-minute, United States-based online survey fielded from December 2021 to January 2022 was sent to physicians, nurse practitioners, and physician assistants who reported a primary care or psychiatry specialty currently treating drug-induced movement disorders and prescribed benztropine. Results: The health care claims analysis included 112,542 patients. Polypharmacy and multiple comorbidities were frequent characteristics in this population; 54.1% of patients had ≥ 2 comorbidities at baseline, and 59.1% had claims for > 10 medications. Benztropine was used for > 3 months in > 50% of the population. Health care costs and resource utilization were high, with mean all-cause pharmacy and outpatient costs totaling $11,755. Survey results from 349 primary care or psychiatry health care providers indicated that benztropine is often used in non-tardive dyskinesia drug-induced movement disorders but frequently continued for > 3 months or used in tardive dyskinesia. In this study, psychiatry providers prescribed benztropine in line with guideline recommendations more often than primary care providers; however, < 40% indicated familiarity with 2020 American Psychiatric Association Practice Guideline for the Treatment of Patients with Schizophrenia. Conclusions: These complementary analyses suggest that benztropine is used long-term in non-tardive dyskinesia drug-induced movement disorders and in tardive dyskinesia despite risks of worsening tardive dyskinesia or adverse effects.

Abstract
Abstract
Introduction
Sleep disruptions in patients with Parkinson’s disease (PD) include difficulty falling/staying asleep, which can contribute to daytime sleepiness and overall worsening of health, mood, and quality of life. Although sleep disturbances in PD are multifactorial, nighttime motor symptoms can negatively affect sleep. To better understand how “OFF”-episodes affect sleep, post-hoc analyses were conducted using baseline data from two phase 3 studies of opicapone, an approved once-daily adjunctive treatment to levodopa/carbidopa (LD/CD) in patients with PD experiencing motor fluctuations.
Methods
In BIPARK-1 and BIPARK-2, participants recorded sleep/awake periods, “OFF”-time, and “ON”-time in 24-hour PD diaries. Sleep metrics included sleep duration, awakenings after sleep onset, and percent of sleep time spent awake. “OFF”-times included “OFF” before sleep (OBS), nighttime “OFF” (NTO), and early morning “OFF” (EMO). Data at baseline were pooled across treatment groups and analyzed descriptively. Mean values are presented with standard deviations (±SD).
Results
Baseline data from 1010 participants were pooled for analysis. Among 964 participants with available sleep metrics, mean total sleep duration was 7.6 (±1.5) hours and longest duration of uninterrupted sleep was 7.2 (±1.9) hours. 332/964 (34.4%) participants experienced an “OFF”-episode before going to sleep and the mean duration of this OBS was 1.8±1.2 hours. 158/964 (16.4%) participants awoke after sleep onset; of these, 128/158 (81.0%) awoke in an “OFF”-state and the mean duration of this NTO was 1.0 (±0.5) hours. Among these 128 participants, the mean number of awakenings was 1.3 (±0.7) and percent of sleep time spent awake was 15.4% (±9.6%). 898/1005 (89.4%) participants experienced an “OFF”-episode upon waking up in the morning and the mean duration of this EMO was 1.5 (±0.9) hours.
Conclusion
Results from this pooled analysis indicate that 34.4% of participants experienced an “OFF”-episode before going to sleep. Moreover, 81.0% of participants who woke up during the night were in an “OFF”-state upon awakening. Reducing “OFF”-episodes before and during the nighttime may help improve sleep in patients with PD, in turn potentially improving quality of life and daytime motor performance.
