Clinical Utility of a Genomic Predictor Test on the Management of Cardiorenal Complications of Type 2 Diabetes

Overview

The goal of this pragmatic trial is to provide Real World Evidence (RWE) on the impact of the result of a polygenic risk prediction test of cardiorenal complications of T2D, so that more patients at high risk of these complications achieve over an 18 months period, recommended therapeutic targets. This will be demonstrated as a significant improvement in a composite value including HbA1c or systolic blood pressure (SBP) or albuminuria (UACR), or glomerular filtration rate (GFR) lowering. Researchers will compare the recommended therapeutic targets of uninformed and informed patients to see if the knowledge of the risk by the patients and their treating physicians improves achievement of these targets. Participants will: Have a saliva sampling to determine the genetic risk. Visit the clinic once every 3 months for checkups and tests Answer two questionnaires on quality of life.

Type 2 diabetes (T2D) increases the risk of developing serious cardiovascular and kidney complications that represent a major burden for both patients and our healthcare system. Currently, patients with T2D are treated according to guidelines, with varied results in terms of systolic blood pressure (SBP), blood glucose (HbA1c), urine albumin-creatinine ratio (UACR) and glomerular filtration rate (GFR) target achievement. OPTITHERA has developed the first genomic test to predict the risk of cardiorenal complications that will allow early and personalized treatment of patients with T2D who are at high risk using Polygenic risk score. It is proposed that knowledge of the risk of developing complications of diabetes will have a positive effect on the care pathway of diabetic patients: the patient will be able to actively participate in their care and their doctor will be able to adapt his treatment to his personal risk, especially if his patient is at high risk of complications. Objective: To provide Real World Evidence (RWE) on the impact of the result of a PRS prediction test on the risk of complications of T2D, so that patients at high risk of complications achieve, over an 18-month period, recommended targets for systolic blood pressure (≤130 mmHg) or HbA1c (\<7.0%), or decreased albuminuria grade, GFR decline, while avoiding severe hypoglycemia and falls. This will be demonstrated as a significant improvement in composite value including HbA1c or systolic blood pressure (SBP) or albuminuria (UACR). Methodology: Multicenter Study: A) Pragmatic trial designed to evaluate the effectiveness of GENOCORDIA PRS testing in real-life routine practice conditions. B) Randomization of participants into informed and uninformed populations of the PRS test result. C) Adaptive trial for the treatment of subjects initially uninformed of their PRS test result. Estimated number of participants: 2714 participants randomized into two groups. Estimated study enrollment duration= 9 months. Estimated total study duration = 36 months. 18 months follow-up (7 visits).
