Background: Treatment of schizophrenia and major depressive disorder (MDD) with atypical antipsychotics (AAPs) show improved efficacy and reduced side effect burden compared with older antipsychotic medications. However, a risk of treatment-emergent adverse events (TEAEs) remains. TEAEs are hard to quantify and perspectives on the importance of TEAEs differ across patients and between patients and physicians. The current study is a qualitative assessment that investigates TEAEs of AAPs from both patient and physician perspectives to provide better understanding of the occurrence and burden of TEAEs associated with these medications. Methods: Focus groups comprised of patients with MDD and interviews with patients with schizophrenia were conducted at two qualitative research facilities, along with a physician focus group at one of the facilities. Information collected from patients included an exhaustive list of TEAEs experienced, and the frequency and level of bother of each TEAE; from psychiatrists, information included an exhaustive list of TEAEs based on personal observations and patient report, frequency of TEAEs, clinically important TEAEs, and levels of patient-perceived bother. Standard qualitative analysis methods were used to identify, quantify, characterize, and summarize patterns found in the data collected. Results: A total of 42 patients (25 with MDD and 17 with schizophrenia) and 4 psychiatrists participated in the study. TEAEs reported as bothersome across both patients groups included cognitive issues, weight gain and/or increased appetite, low energy, extrapyramidal symptoms (EPS), and need to sleep/excessive sleep/excessive sleepiness. TEAEs considered more bothersome by patients with schizophrenia were weight gain, low energy, EPS, mental anxiety, and increased positive symptoms; those considered more bothersome by patients with MDD were cognitive issues, somnolence/sedation, and flat/restricted affect. TEAEs considered most clinically important by psychiatrists included metabolic syndrome, weight gain, neutropenia, hyperglycemia, and QT prolongation; those TEAEs considered most bothersome to patients from physicians' perspectives included weight gain, reduced sexual desire or performance, EPS, akathisia, and hormonal issues. Conclusions: The wide range of TEAEs that are both frequent and bothersome and the variation in perceived burden according to diagnosis highlight the need for a tailored TEAE-awareness approach when choosing an AAP.

Background: Moderate to severe plaque psoriasis (with or without psoriatic arthritis) places significant burden on patients’ lives.Objective: Explore and document patients’ experiences of living with psoriasis, including symptoms, treatments, impact on daily lives and patient-reported functioning.Methods: In a US-based, non-interventional study, narrative interviews were conducted at baseline and again within 16 weeks. In interviews, patients with moderate to severe psoriasis indicated symptoms, ranked symptoms according to level of bother and indicated areas of their lives affected by psoriasis. Transcripts of interviews were coded for themes. Measurements of psoriasis severity including BSA, PGA and PASI were recorded.Results: Symptoms reported most frequently included flaking/scaling (non-scalp areas), itching/scratching and rash, while the most bothersome symptoms were itching/scratching, flaking/scaling (non-scalp areas) and skin pain. Frequently reported impact areas were social and emotional.Conclusion: Broad-reaching interviews with patients with psoriasis show that these patients suffer in many aspects of their lives and in ways not indicated by typical psoriasis severity measures. Patients with psoriatic arthritis reported symptoms and disease-related complications at higher rates than those without arthritis. Physicians’ explorations of the effect of psoriasis on patients’ life events could aid in managing these patients. [ABSTRACT FROM AUTHOR]

Background: Improved patient life engagement is a meaningful treatment goal in schizophrenia that cannot be satisfactorily measured using existing tools. This research aimed to determine whether certain items from the Positive and Negative Syndrome Scale (PANSS) can assess patient life engagement in schizophrenia., Methods: Three approaches were used to identify PANSS items that reflect patient life engagement: (1) a panel discussion with expert psychiatrists (n = 4); (2) interviews with patients with schizophrenia (n = 20); and (3) a principal component analysis to explore clustering of items (n = 954 from three randomized controlled trials). Internal consistency was assessed by Cronbach's alpha and item-total correlations. A minimal clinically important difference (MCID) was determined by anchor- and distribution-based methods., Results: Expert psychiatrists identified 11 relevant items, and patients rated 13 items as "very relevant" to patient life engagement, most of which clustered in the principal component analysis. Considering all results, a composite set of 14 PANSS items that may be relevant to patient life engagement in schizophrenia was devised: P2, N1, N2, N3, N4, N5, N6, N7, G6, G7, G11, G13, G15, G16 (Cronbach's alpha, 0.84; item-total correlations, 0.35-0.56, indicating acceptable correlation with the underlying concept; exception: G6 [depression], 0.19). An MCID of 5 points (small/moderate improvement) or 10 points (large improvement) may be appropriate., Conclusions: A subset of 14 PANSS items may be used to reflect patient life engagement in clinical practice/trials in schizophrenia, complementing the results of traditional psychiatric symptom scales with a patient-centered outcome that is relevant to real-world treatment goals., Competing Interests: Declaration of competing interest Zahinoor Ismail has received grant support from CIHR, NIH, Brain Canada, and Weston Foundation, and has served as a consultant for Eisai, Eli Lilly, Lundbeck, Novo Nordisk, Otsuka and Roche.

Background: Familial chylomicronemia syndrome (FCS) is a rare metabolic disorder that impacts physical, emotional, social, and cognitive functioning. The FCS-Symptom and Impact Scale (FCS-SIS) patient-reported outcome (PRO) measure assesses common symptoms and impacts of FCS. This study was conducted to evaluate cross-sectional psychometric properties of the FCS-SIS and its scoring method., Methods: This multisite, cross-sectional, observational study of individuals with FCS was conducted in the United States and Canada. Participants completed a survey composed of 7 PRO measures, including the FCS-SIS, and questions about clinical characteristics and demographics. The structure of the FCS-SIS was evaluated using inter-item and item-scale correlations and internal consistency reliability. Construct, known-groups, and criterion validity were evaluated by examining associations between FCS-SIS item and composite scores and other measures included within the survey., Results: Most of the 33 participants were female (63.6%) and White (78.1%). On average, participants reported first noticing FCS symptoms at ~16 years, with abdominal pain the most frequently reported initial symptom (n=20). Participants reported 2.5 acute pancreatitis attacks on average over the past year. Average FCS-SIS symptom item scores ranged from 1.8 to 3.9 (on a 0-to-10 scale [none-to-worst-possible]) within the 24-hour recall period, with an average Symptom composite score of 2.7. The average impact item scores on the FCS-SIS ranged from 1.6 to 3.0 (on a 0-to-4 scale), with an average Impact composite score of 2.1. Inter-item correlations between the FCS-SIS Symptom items ranged from 0.32 to 0.78. Corrected item-total correlations were highly satisfactory for Impact items, ranging from 0.62 to 0.85. All a priori validity hypotheses were supported by observed correlations and score differences between known groups., Conclusion: The results of this study support the structure, reliability, and validity of the FCS-SIS, laying the psychometric groundwork for longitudinal evaluation of its utility in assessing treatment benefit in FCS clinical studies., Competing Interests: TMB and SF are full-time employees of RTI Health Solutions, an independent nonprofit research organization, which was retained by Ionis Pharmaceuticals to conduct the research which is the subject of this manuscript.

Background: Metachromatic leukodystrophy (MLD) is a rare disease with three forms based on the age at onset of signs and symptoms. The objective of this study was to develop a caregiver-reported clinical outcome assessment that measures impairments in physical functioning related to activities of daily living in patients with juvenile MLD., Methods: A targeted literature review and exploration of proprietary research, including a conceptual model, were conducted. Concept elicitation interviews were conducted to elicit additional concepts related to impairments in patients' physical functioning with caregivers of five individuals with juvenile MLD. Based on the research review and concept elicitation interviews, the conceptual model was updated and the Impact of Juvenile Metachromatic Leukodystrophy on Physical Activities (IMPA) scale draft items were created. Cognitive debriefing interviews were conducted with six additional caregivers to finalize the conceptual model and to refine the IMPA scale., Results: Initially, 17 potentially important concepts were identified and addressed in the draft IMPA scale. Following the cognitive debriefing interviews, 15 activities/items remained: brush teeth, comb/brush hair, bathe/shower, dress self, eat, drink, use pencil/crayon, sit upright, use toilet, get on/off toilet, walk, use stairs, get in/out of bed, get in/out of chair/wheelchair, and get in/out of vehicle. Items that did not uniquely contribute to the purpose of the instrument were removed., Conclusion: The IMPA scale, developed according to regulatory standards, provides a means of detecting changes in activities of daily living in individuals with juvenile MLD and can hence be used in future studies to measure benefits of therapeutic interventions., Competing Interests: This study was conducted in accordance with the ethical principles outlined in the Declaration of Helsinki 2008 and reviewed and approved by the RTI International Institutional Review Board.
