Earlier Use of Long-Acting Injectable Paliperidone Palmitate Once-Monthly versus Oral Antipsychotics in Patients with Schizophrenia: An Integrated Patient-Level Meta Analysis of the PROSIPAL and PRIDE Studies.

Purpose: A previous integrated patient-level analysis demonstrated a significant benefit of implementing once-monthly injectable paliperidone palmitate (PP1M) earlier in the treatment course for schizophrenia. Earlier therapeutic interventions during the first 3-5 years after disease onset can positively impact long-term outcomes in schizophrenia. This present analysis evaluated the risk of relapse both overall and by different durations of illness (0-3 years, >3-5 years, and >5 years from diagnosis) in adult patients with schizophrenia who received PP1M or oral antipsychotics (OAPs).

Comparing two transitioning strategies to paliperidone palmitate once-every-6-months.

Background: A double-blind, randomized, active-controlled, parallel-group, noninferiority trial (NCT03345342) demonstrated that paliperidone palmitate once-every-6-months (PP6M) was noninferior to paliperidone palmitate once-every-3-months (PP3M) in preventing relapse in clinically stable adults with schizophrenia. This post hoc analysis assessed efficacy and safety following transition to PP6M from paliperidone once-monthly (PP1M) versus PP3M.

Methods: Adults with schizophrenia who were clinically stable on moderate/high doses of PP1M or PP3M were randomly assigned 1:2 to dorsogluteal PP3M or PP6M treatment for 12 months.

Setting/participants: 33 adult patients with schizophrenia were enrolled at 3 sites across Rwanda.

Predictors of response and remission in patients with treatment-resistant depression: A post hoc pooled analysis of two acute trials of esketamine nasal spray.

This exploratory post hoc analysis of two pooled 4-week, phase 3, double-blind, placebo- and active-controlled studies that compared esketamine nasal spray plus a newly initiated oral antidepressant (ESK+AD; n = 310) with a newly initiated oral AD plus placebo nasal spray (AD+PBO; n = 208) in patients with treatment-resistant depression (TRD) examined baseline patient demographic and psychiatric characteristics as potential predictors of response (≥50% reduction from baseline in Montgomery-Åsberg Depression Rating Scale [MADRS] total score) and remission (MADRS total score ≤12) at day 28. Overall, younger age, any employment, fewer failed ADs in the current depressive episode, and reduction in Clinical Global Impression-Severity (CGI-S) score at day 8 were significant positive predictors of response and remission at day 28. Treatment assignment was an important predictor of both response and remission.

Adverse Events and Measurement of Dissociation After the First Dose of Esketamine in Patients With TRD.

Background: "Dissociation" comprises distinct phenomena, some of which are associated with esketamine treatment and some may overlap with positive symptoms of psychosis. Relationships between dissociation and psychotic symptoms assessed by -clinician report vs conventional rating scales were investigated in a post hoc analysis of data from the initial treatment session in an -open-label, -long-term safety, phase 3 study of esketamine plus a newly initiated oral antidepressant in patients with treatment-resistant depression.

Methods: Adverse events of dissociation or psychosis were examined via investigator report and the Clinician Administered Dissociative States Scale (CADSS) and Brief Psychiatric Rating Scale-Plus, respectively, 40 minutes post first esketamine dose.

Intranasal esketamine effectively treats treatment-resistant depression in adults regardless of baseline irritability.

Objective: To evaluate the impact of baseline irritability on clinical outcomes in adults with treatment-resistant depression (TRD) treated with fixed or flexible doses of esketamine nasal spray plus a newly initiated oral antidepressant (ESK+AD) and to explore whether treatment with ESK affects irritability symptoms over time.

Methods: This was a post hoc analysis of pooled data from two 4-week, double-blind, phase 3 studies: TRANSFORM-1 (NCT02417064) and TRANSFORM-2 (NCT02418585). Adults with TRD (n = 560) were randomly assigned to ESK+AD or placebo nasal spray plus oral antidepressant (AD+PBO).

Health care resource utilization and costs in patients receiving long-acting injectable vs oral antipsychotics: A comparative analysis from the Disease Recovery Evaluation and Modification (DREaM) study.

Given relapse frequency early in the course of schizophrenia, recently diagnosed patients may benefit from longacting injectable antipsychotics, which are associated with reduced risk of relapse and hospitalization compared with oral antipsychotics (OAPs). To compare health care resource utilization (HCRU) and costs in patients with recent-onset schizophrenia treated with continuous paliperidone palmitate (PP) or continuous OAP or who switched from OAP to PP. In this analysis, we combined the 2 randomized phases of the prospective, open-label Disease Recovery Evaluation and Modification (DREaM) clinical study using the principal stratification method to generate 3 treatment strategies: continuous PP for 18 months (PP-PP), continuous OAP for 18 months (OAP-OAP), and initial OAP switched to PP after 9 months (OAP-PP).

Dispersion of cognitive performance test scores on the MATRICS Consensus Cognitive Battery: A different perspective.

Objective: Persons with schizophrenia exhibit greater neurocognitive test score dispersion. Here, we seek to characterize dispersion on the Neurocognitive Composite subtests of the Measurement of Treatment Research to Improve Cognition in Schizophrena Consensus Cognitive Battery (MCCB) and determine the relative effects of different antipsychotic formulations on dispersion and mean performance.

Method: In this post hoc analysis of the DREaM study (NCT02431702), which compared treatment with paliperidone palmitate (PP) long-acting injectable with oral antipsychotic (OAP) treatment over 18 months, dispersion in MCCB neurocognitive subtest performance was calculated for each participant by visit (test occasion).
