Clinical and Amyloid Screen Failure Rates in Episodic Memory Measures of Early AD Trials

This study examined two episodic memory measures – the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and the Cogstate International Shopping List Test (ISLT) – to compare their clinical and amyloid screen failure rates in early AD trials.

Error Rates and Data Integrity: eCOA versus Paper Administration of the PANSS

Methodological Question: Does the use of electronic clinical outcomes assessment (eCOA) impact rates of scoring errors as evaluated with the ISCTM working group consensus method for PANSS data?

Among the Conclusions: eCOA administrations of the Positive and Negative Syndrome Scale (PANSS) are less susceptible to scoring inconsistencies and error compared to those administered on paper.

Independent and Site-based Ratings of Symptom Severity in Pharmacogenetics Clinical Trials

Personalized medicine and pharmacogenomics hold strong promise for psychiatry. Studies in this area require novel approaches to ensure endpoint reliability and validity, reduce the impact of treatment unblinding, and minimize other confounds that reduce signal detection. At the American Psychiatric Association Annual Meeting, MedAvante-ProPhase presented analysis of a combination of novel assessment methods, including remote, independent ratings, to evaluate adherence to inclusion criteria and efficacy in pharmacogenetics clinical trials.

Reliability Findings from the Unified Global Training Program for the Brief Negative Symptoms Scale (BNSS)

MedAvante-ProPhase presented an analysis of reliability in administration of the Brief Negative Symptoms Scale (BNSS) across multiple studies and countries at the 14th International Society for CNS Clinical Trials and Methodology (ISCTM) Scientific Conference. BNSS achieved overall good-to-excellent inter-rater reliability among raters from different countries and cultures.
