MODELING THE EXPECTATIONS FOR IMPROVEMENT IN OSTEOARTHRITIS TRIALS TO ENHANCE MANAGEMENT STRATEGIES 

April 12, 2024

Objective: The expectations of improvement among subjects participating in a Randomized Controlled Trials (RCT) are one of the features most frequently associated with the placebo response. Consequently, it becomes a pivotal factor for understanding treatment effect, particularly in chronic pain RCTs such as Osteoarthritis (OA). There are multiple techniques to account for these expectations in studies,

Using aggregated site features computed with the MPsQ to allow a better monitoring of sites in clinical trials

November 3, 2023

Using aggregated site features computed with the MPsQ to allow a better monitoring of sites in clinical trials Objective:   The MPsQ is an assessment characterizing the profile of the subjects participating to a Randomized Controlled Trial (RCT) to predict their behaviors in the study (placebo response, adherence, …). This analysis aimed to determine whether individual responses collected through the MPsQ could

Accounting for the high reduction of power due to floor effect in design of randomised controlled trials

March 6, 2023

Purpose  Outcomes in Randomized Controlled Trials (RCT) are often computed as changes from baseline of finite scales (e.g., pain assessments going from 0 to 10). When subjects receive effective treatment over time they may reach the limit of a finite scale. In that case, the score limitation at the bottom of the finite scale, called

Leveraging historical data to optimize the number of covariates and their explained variance in the analysis of randomized clinical trials

January 11, 2022

The amount of data collected from patients involved in clinical trials is continuously growing. All baseline patient characteristics are potential covariates that could be used to improve clinical trial analysis and power. However, the limited number of patients in phases I and II studies restricts the possible number of covariates included in the analyses. In

Impact of excluding highly variable pain subjects on the treatment estimation

November 8, 2021

The baseline pain variability (BPV) has often been presented as positively correlating with the placebo response (PR) and associated with a lack of consistency in the subjects’ pain evaluation. Excluding high BPV subjects should then improve the precision of the treatment response. Another common method to increase the essay sensitivity is to adjust the analysis for covariates
