Trial Outcomes & Findings for A Study of the Safety and Efficacy of Pimavanserin (ACP-103) in Patients With Parkinson's Disease Psychosis (NCT NCT00477672)

NCT ID: NCT00477672

Last Updated: 2017-05-17

Results Overview

Antipsychotic Efficacy was defined as a decrease in the severity and/or frequency of hallucinations and/or delusions. This is measured as the change from baseline (Day 1) to Day 42 in the Scale for the Assessment of Positive Symptoms - Hallucinations and Delusions scales (SAPS-H+D) score for the ITT Analysis Set. The possible total score is 0 to 100 and a negative change in score indicates improvement. Analysis Method: Analysis of Covariance (ANCOVA) and missing data was imputed using Last Observation Carried Forward (LOCF) method.

PRIMARY outcome

Timeframe: Each study visit (i.e. Days 1, 8, 15, 29 and 42)

Population: This is the "Intent to Treat" population, defined as patients who received at least one dose of study drug, and had both the baseline SAPS assessment and at least one post-baseline SAPS assessment.

Antipsychotic Efficacy was defined as a decrease in the severity and/or frequency of hallucinations and/or delusions. This is measured as the change from baseline (Day 1) to Day 42 in the Scale for the Assessment of Positive Symptoms - Hallucinations and Delusions scales (SAPS-H+D) score for the ITT Analysis Set. The possible total score is 0 to 100 and a negative change in score indicates improvement. Analysis Method: Analysis of Covariance (ANCOVA) and missing data was imputed using Last Observation Carried Forward (LOCF) method.

SECONDARY outcome

Timeframe: Each study visit (i.e. Days 1, 8, 15, 29 and 42)

Population: This is the "Per Protocol" population, which includes subjects in the ITT analysis set, who were free of important protocol deviations, as defined before database lock and unblinding. Subjects were analyzed according to the treatment actually received.

Motor symptoms were measured using the change from baseline (Day 1) to Day 42 in the combined score of the Unified Parkinson's Disease Rating Scale (UPDRS) Part II (Activities of Daily Living) and Part III (Motor Examination) using the per-protocol (PP) analysis set. The possible total score is 0 to 160 and a negative change in score indicates improvement. Analysis Method: ANCOVA, and missing data was imputed using LOCF. The UPDRS Parts II+III score was analyzed by constructing 2-sided 95% confidence intervals (CIs) on the difference between each pimavanserin dose group and placebo mean change from baseline. Non-inferiority was concluded if the upper limit of the CI was less than or equal to 5.
