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

Modelling of PNP and OA Placebo Response: Working towards a unique model of the placebo response in chronic pain?

January 20, 2020

In analgesia randomized clinical trials (RCTs), the magnitude and the variability of the placebo response negatively impacts the ability to demonstrate superiority of active compounds compared to placebo. The first objective of this analysis was to investigate parameters influencing the placebo response in PNP as a way to control for this major confounding factor.

Identification Of Peripheral Neuropathic Pain Sensory Phenotypes Based On Specific Combinations Of Symptoms Identified With The NPSI (Neuropathic Pain Symptom Inventory)

August 18, 2019

One way to better personalized the treatment of peripheral neuropathic pain (PNP) would be to identify specific sensory phenotypes of patients responding to different classes of drugs.

Leveraging Historical Data For High-dimensional Covariate-adaptive Randomization, A Machine Learning Approach.

August 7, 2019

There is a continuous growth in data collected in clinical trials. Many of those patient’s characteristics are potential confounding factors. Ideally, these factors should be accounted for in the randomization process to balance study arms and reduce the variability of the estimated treatment effect.

Correcting For The Individual Patient Regression To The Mean Effect

August 7, 2019

Often, the primary endpoint of RCTs is defined as a change from baseline of a continuous outcome. In
such cases, regulators recommend including the outcome’s baseline value as a covariate in the
statistical analysis. Regression to the mean can explain the benefits of this procedure.

Putting Patient Uniqueness at the heart of Innovation

March 6, 2019

Access to innovative therapies remains an issue. In certain diseases, the magnitude and variability of individuals’ placebo response (IPR) can confound detection of positive results in clinical trials. Despite the best efforts and investments by pharmaceutical industry stakeholders, patients are still waiting for optimal treatments.
