A Study of LY2140023 in Patients With Schizophrenia

Phase 3

Terminated

Conditions: Schizophrenia

Interventions: Drug: LY2140023
Drug: Placebo

Registration Number: NCT01307800

Lead Sponsor: Denovo Biopharma LLC

Brief Summary: The purpose of this study is to determine whether at least 1 dose level of LY2140023 given to acutely ill patients with schizophrenia will demonstrate significantly greater efficacy as compared to placebo.

Detailed Description: The primary objective of this study was to test the hypothesis that at least 1 dose level of LY2140023, given orally to patients with schizophrenia at doses of 80 mg twice daily (BID), 40 mg BID, or 10 mg BID, would demonstrate significantly greater efficacy than placebo at Visit 9, as measured by the change from baseline in the Positive and Negative Syndrome Scale (PANSS) total score.

This was a multicenter, randomized, double-blind, parallel, fixed-dose, Phase 3 study in patients with schizophrenia. The study consisted of 3 periods: a screening and antipsychotic taper phase, a 7-day placebo lead-in phase that was blinded to investigators and patients, and a 6-week active treatment phase.

Eligible patients were those for whom a modification of antipsychotic medication was acutely indicated, in the opinion of the investigator. To be included in the study, patients must have experienced an exacerbation of their illness within the 2 weeks prior to study entry, leading to an intensification of the level of psychiatric care.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in the Positive and Negative Syndrome Scale (PANSS) Total Score	Baseline, Week 6	The PANSS scale assessed participants (pts) for positive symptoms, negative symptoms, and general psychopathology specifically associated with schizophrenia. The scale consisted of 30 items. Each item was rated from 1 (absence of symptoms) to 7 (symptoms extremely severe). The sum of the 30 items was defined as the PANSS total score and ranged from 30 to 210. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in the Clinical Global Impression-Severity (CGI-S) Scale	Baseline, Week 6	The CGI-S was a single item scale that measured severity of illness at the time of assessment. Scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill participants). The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.
Change From Baseline in Abnormal Involuntary Movement Scales (AIMS) 1-7 Total Score	Baseline, Week 6	The AIMS was a 12-item scale designed to record the occurrence of abnormal involuntary (dyskinetic) movements. Items 1 to 10 were rated on a 5-point scale from 0 (no dyskinetic movements) to 4 (severe dyskinetic movements). Items 11 and 12 were 'yes/no' questions regarding the dental condition of a participant. The sum of Items 1 through 7 was defined as the AIMS 1-7 total score and ranged from 0 to 28. Higher scores indicated a greater severity of illness. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.
Change From Baseline in the 16-Item Negative Symptoms Assessment (NSA-16) Total Score	Baseline, Week 6	The NSA-16 scale was used to help clinicians rate behaviors (not psychopathology) commonly associated with negative symptoms of schizophrenia. The scale contained 16 items and each item was rated from 1 (normal behavior) to 6 (extreme, abnormal behavior). The sum of the 16 items was defined as the NSA-16 total score and ranged from 16 to 96. Higher scores indicated a greater severity of illness. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.
Change From Baseline on Subjective Well-Being Under Neuroleptic Treatment Scale - Short Form (SWN-S) Total Score	Baseline, Week 6	The SWN-S was a self-rated scale that measured subjective well-being for the previous 7 days. The SWN-S consisted of 20 items each rated using a 6-point scale from 1 (not at all) to 6 (very much). The sum of the 20 items was defined as the SWN-S total score and ranged from 20 to 120, with higher scores indicating better subjective well-being. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.
Number of Participants Who Discontinued	Randomization up to Week 6	The reasons for study discontinuation are located in the Participant Flow.
Time to Discontinuation	Randomization up to Week 6	The time to discontinuation, due to any reason, was defined as the total number of days between the randomization date and discontinuation date. Participants who completed the study period were censored. The time to discontinuation was analyzed using Kaplan-Meier estimated survival curves.
Change From Baseline in the Positive and Negative Syndrome Scale (PANSS) Total Score in a Predefined Subpopulation of Schizophrenia Participants	Baseline, Week 6	The PANSS scale assessed participants for positive symptoms, negative symptoms, and general psychopathology specifically associated with schizophrenia. The scale consisted of 30 items. Each item was rated from 1 (absence of symptoms) to 7 (symptoms extremely severe). The sum of the 30 items was defined as the PANSS total score and ranged from 30 to 210. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, and gender, as well as the continuous fixed covariates of baseline score, and baseline score-by-visit interaction.
Change From Baseline in the Personal and Social Performance (PSP) Score in a Predefined Subpopulation	Baseline, Week 6	The PSP scale was a 100-point, single item scale that assessed 4 domains of functioning (personal and social relationships, socially useful activities, self-care, and disturbing and aggressive behaviors). PSP scores ranged from 1 (risk of death) to 100 (excellent functioning) in all 4 domain areas. A higher score indicated a better health state. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, and gender, as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.

Time to Response	Baseline up to Week 6	Time to response is the number of days from randomization until a ≥30% decrease from lead-in baseline in Positive and Negative Syndrome Scale (PANSS) total score. Participants who did not have a response were censored. The PANSS scale assessed participants for positive symptoms, negative symptoms, and general psychopathology specifically associated with schizophrenia. The scale consisted of 30 items. Each item was rated from 1 (absence of symptoms) to 7 (symptoms extremely severe). The sum of the 30 items was defined as the PANSS total score and ranged from 30 to 210.

Change From Baseline on the European Quality of Life-5 Dimension (EQ-5D) Questionnaire	Baseline, Week 6	The EQ-5D was a generic, multidimensional, health-related, quality-of-life instrument. The overall health state score was self-reported using a visual analogue scale (VAS) from 0 (worst imaginable health state) to 100 (best imaginable health state). The least squares (LS) mean was estimated using an analysis of covariance (ANCOVA) model that included terms for treatment, pooled investigative site, gender, baseline score and predefined subpopulation ('yes/no').
Change From Baseline on Schizophrenia Resource Utilization Module (S-RUM): Emergency Room (ER) Visits and Outpatient Visits	Baseline and Week (Wk) 6	The S-RUM was a 31-item questionnaire to assess the participant's occupation (work and home), living arrangements, encounters with law enforcement, victimization, ER visits, and outpatient medical visits for a specified period of time. Item 1 asked about the number of ER or equivalent facility visits a participant had for psychiatric (psych) illness during the last year \[baseline (BL) assessment\] or since the last assessment (post-baseline assessment). Item 2 asked about the number of ER or equivalent facility visits a participant had for non-psychiatric (non-psych) illness or injury during the last year (BL assessment) or since the last assessment (post-BL assessment). Item 5 asked about the number of outpatient visits to other physicians (not psychiatrists or dentists) a participant had during the last year (BL assessment) or since the last assessment (post-BL assessment).
Percentage of Participants With a Change From Baseline in Suicidal Behaviors and Ideations Measured by the Columbia-Suicide Severity Rating Scale (C-SSRS)	Baseline up to Week 6	The C-SSRS captured the occurrence, severity, and frequency of suicide-related thoughts and behaviors during the assessment period. Suicidal behavior: a "yes" answer to any 1 of 5 suicidal behavior questions (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide). Suicidal ideation: a "yes" answer to any 1 of 5 suicidal ideation questions (wish to be dead, and 4 different categories of active suicidal ideation). The percentage of participants with treatment-emergent suicidal ideation or behavior (with a change from baseline in C-SSRS) was calculated as the number of participants with an increase in suicidal behavior or ideation over lead-in baseline, divided by the total number of participants multiplied by 100.
Change From Baseline in Prolactin	Baseline, Week 6
Change From Baseline in Simpson-Angus Scale (SAS) Total Score	Baseline, Week 6	The SAS was used to measure Parkinsonian-type symptoms in participants exposed to antipsychotics. The scale consisted of 10 items and each item was rated on a 5-point scale from 0 (complete absence of the condition) to 4 (the presence of the condition in extreme form). The sum of the 10 items was defined as the SAS total score and ranged from 0 to 40. Higher scores indicated a greater severity of illness. The least squares (LS) mean was estimated using a mixed-effects model with repeated measures (MMRM) that included the fixed, categorical effects of treatment, pooled investigative site, visit, treatment-by-visit interaction, gender, and predefined subpopulation ('yes/no'), as well as the continuous, fixed covariates of baseline score and baseline score-by-visit interaction.
