ObjectifsÉvaluer l’amélioration fonctionnelle chez des patients atteints de schizophrénie sous palmitate de paliperidone (PP) à doses flexibles après échec d’un traitement par antipsychotiques oraux.MéthodesAnalyse menée dans deux sous-groupes de patients atteints de schizophrénie : aigus (n = 202) et non aigus (n = 593) après échec d’un traitement par antipsychotiques oraux, inclus dans une étude internationale, prospective, de six ***ères d’évaluationChangement du score total à la PANSS (Positive and Negative Syndrome Scale), à la PSP (Personal and Psychosocial Performance scale), et à la Mini-ICF-APP (Mini International Classification of Functionality, Disability and Health Rating for Activity and Participation Disorders in Psychological Illnesses).RésultatsLes deux sous-groupes ont présenté une amélioration significative du score total à la PANSS : de 98,5 ± 20,1 à l’inclusion à 67,4 ± 24,0 à la fin de l’étude (diminution moyenne = −31,0 ± 29,0) chez les patients aigus et de 71,5 ± 14,6 à 59,7 ± 18,1 (diminution moyenne = −11,7 ± 15,9) chez les patients non aigus. Cette réponse thérapeutique était associée à une augmentation significative du score total à la PSP de 43,9 ± 15,0 à 62,9 ± 17,1 (amélioration moyenne = 19,0 ± 18,7, p <0,0001) chez les patients aigus, et de 58,1 ± 13,4 à 66,1 ± 15,7 (amélioration moyenne =8,0 ± 14,0, p < 0,0001) chez les patients non aigus. Il existait une amélioration significative du score à la Mini-ICF-APP qui diminuait de 26,8 ± 8,5 à 18,5 ± 9,8 (diminution moyenne = −8,0 ± 10,4, p < 0,0001) chez les patients aigus et de 19,8 ± 7,9 à 15,9 ± 8,8 (diminution moyenne = −4,0 ± 7,5, p < 0,0001) chez les patients non ***’amélioration symptomatique sous PP à doses flexibles chez des patients aigus ou non-aigus atteints de schizophrénie après échec d’un traitement par antipsychotique oral s’est accompagnée d’une amélioration fonctionnelle cliniquement significative.

Introduction and objectives To explore safety, tolerability, treatment response and hospitalizations in adult patients with schizophrenia treated with long-acting injectable risperidone (RLAI) or oral antipsychotic standard of care (oAP) in routine clinical practice. Methods Prospective one-year open-label non-interventional study exploring flexible doses of RLAI and oAPs. Primary outcome was the number of hospitalizations from baseline to endpoint. Additional outcomes were changes in the Clinical Global Impression of Schizophrenia (CGI-SCH), patient functioning (Global Assessment of Functioning) and treatmentemergent adverse events (TEAEs). Results The intent-to-treat analysis included 561 patients on RLAI and 522 patients on oAPs (44% female gender, mean age (±SD) 42.2±13.1 years). Demographics and baseline characteristics were comparable, yet RLAI-treated patients had higher disease severity, lower baseline functioning and more substance abuse. The number of hospitalizations did not differ between the two groups while median duration of hospitalization was significantly shorter with RLAI (12.3 vs 20.6 days). Positive, negative, cognitive symptoms, disease severity, patient functioning and medication satisfaction improved significantly better with RLAI than oAPs. The most frequently reported TEAEs (=2% in any group) for RLAI and oral APs were increase of body weight (5.0%; 5.6%), psychotic disorder (2.7%; 4.0%), schizophrenia (2.5%; 3.1%), anxiety (2.3%; 2.7%), insomnia (0.9%; 3.1%) and somnolence (0.4%; 2.5%), respectively. Conclusion This one-year non-interventional study supports results of recent randomized controlled trials that treatment with RLAI is associated with less days spent in hospital, better symptomatic and functional outcomes and higher patient satisfaction with medication compared to oral APs.

The sample size requirement in a thorough QT/QTc study is discussed under a balanced parallel or crossover study design. First, we explore the impacts of various factors on the study power, including the mean effect profile across time and correlation among time points. Then we estimate the variability parameters needed based on multiple historical studies. Different baseline usage is illustrated to have a significant impact on the analysis variability in the parallel studies. Finally, the sample size calculations and recommendations are given for demonstrating a “negative” drug effect and the study assay sensitivity, respectively. [ABSTRACT FROM AUTHOR]

For the generalized biased coin class of randomization procedures, Smythe (1988) proved asymptotic normality of the conditional linear rank test. Clinical trialists often undertake interim analysis to determine whether to stop the trial early for a substantial treatment effect. In this article, we will set up one interim analysis using a conditional randomization test. The joint asymptotic distribution of the interim test statistic and the final test statistic will be explored. We also define the concept of conditional information under a randomization model.
