Leveraging historical data for covariate adjustment in the analysis of randomized clinical trials

October 26, 2021

Scientific Poster presented on October 2021 at the Annual Meeting of the Royal Statistical Society of Belgium. The amount of data collected from patients involved in clinical trials is continuouslygrowing. 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

Should placebo responders be excluded from RCTs?

September 30, 2021

Scientific Poster presented on September 2021 at the International Society for CNS Clinical Trial and Methodology Conference The Methodological Question Being Addressed  Recently, several models predictive of the placebo response in pain RCTs have been published. The most obvious application of these models is the identification and exclusion of placebo responders before randomization in an enriched screening procedure. We investigated the benefit

Modeling of the Placebo Response in Parkinson’s Disease

September 16, 2021

The magnitude and the variability of the placebo response have a confounding influence when testing the superiority of active compounds compared to placebo. Identifying covariates associated with this PD placebo response may help mitigate its effect, increase the study power, and result in more optimal RCT design in future studies.

Towards an automated rating of the MDS-UPDRS motor scores

September 16, 2021

Tools4Patient has developed an IMU-based device where sensors are placed on the tip of the index finger and thumb bilaterally. The device was used in a PD study to record movements during 4 motor tasks of the MDS-UPDRS Part III: finger tapping (FT), pronation/supination of hands (PSH), postural tremor of the hands (PTH) and kinetic tremor of the hands (KTH). This pilot study including 14 PD subjects was single-site, non-randomized, observational with no treatment intervention.

Predicting the Placebo response in OA to Improve the Precision of the Treatment Effect Estimation

April 30, 2021

Scientific Poster presented on April 2021 at the Osteoarthritis Research Society International Meeting. Purpose In osteoarthritis (OA) randomized clinical trials (RCTs), the magnitude and the variability of the placebo response have a negative influence when testing the statistical superiority of active compounds compared to placebo. Furthermore, the magnitude of this effect has tended to increase

Can Daily Self-Assessment Induce A Learning Effect Mitigating Pain Evaluation Error In Randomized Clinical Trials?

April 30, 2021

Scientific Poster presented on April 2021 at the Osteoarthritis Research Society International Meeting. Purpose Questionnaires assessing  patients’ pain level represent the majority of  efficacy endpoints in osteoarthritis (OA) randomized clinical trials (RCTs).  The intrinsic subjectivity of pain may render the evaluation of these questionnaires difficult. In turn, this could explain the high variability observed in the treatment response
