Filter by:To perform an observational analysis to emulate a target trial (i.e., a hypothetical pragmatic trial that would have answered the causal question of interest) comparing the effectiveness and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide 1 receptor agonists (GLP-1RA), dipeptidyl peptidase-4 inhibitors (DPP-4i), and sulfonylureas (SU), at the class and individual agent level, in head-to-head comparisons in patients with type 2 diabetes (T2D).
The primary aim is to determine the effect of participant and provider knowledge of a positive APOL1 status and accompanying guideline based clinical decision support (CDS) on blood pressure management on change in systolic blood pressure (SBP) from baseline to 3 months after randomization among the APOL1 positive participants. Secondary aims are to: 1. Determine the effect of participant and provider knowledge of a positive APOL1 status on the probability of appropriate CKD diagnosis. 2. Determine the effect of participant and provider knowledge of a positive APOL1 status on the probability of receiving a urine microalbumin/creatinine testing and ACE-I/ARB prescription based on results of the urine microalbumin level. 3. Explore cost effectiveness, mediators, moderators, psychobehavioral impact of results disclosure on participants, and effects of participant and provider knowledge of APOL1 status on provider treatment recommendations. PGX Substudy In addition, GUARDD-US will include a substudy to determine the effect of knowledge of genetic test results that predict efficacy of various antihypertensive medications on change in SBP from baseline to 3 months in APOL1 negative individuals. Approximately 6,650 participants of African ancestry age 18-70 with hypertension that either: 1) do not have diabetes and do not have CKD, or 2) have CKD. Participants with diabetes may be included as long as they also have CKD. Population for Main Study: Participants from Randomized Population (above) who test positive for APOL1 Population for PGx Substudy: Participants from Randomized Population (above) randomized to Intervention and who test negative for APOL1 Main Study Analyses: - To determine the effect of participant and provider knowledge of a positive APOL1 status on SBP, we will compare the change in SBP from baseline to 3 months of the Intervention - APOL1 positive group to the change in SBP from baseline to 3 months of the Control - APOL1 positive group using a two sided t-test, as appropriate, with a two-sided type I error of 0.05. - The effect of knowledge of a positive APOL1 status on all secondary endpoints will be compared between Intervention - APOL1 positives to Control - APOL1 positives with the proportion difference test. - Additional analyses will include analysis of time trends in SBP, subset analyses, and exploratory analyses of cost effectiveness, mediators, moderators, psychobehavioral impact of results disclosure on participants, and effects of knowledge of APOL1 status on provider treatment recommendations. Substudy Analyses: All primary and secondary endpoint analyses conducted for the APOL1 main study will be repeated for the PGx substudy focusing on differences in outcomes between APOL1 negative individuals with immediate PGx ROR (PGx Intervention) and APOL1 negative individuals with delayed PGx ROR (PGx Control).
The purpose of this study is to demonstrate non-inferiority of an advagraf based immunosuppressive regimen with slower dose tapering and lower starting dose of Advagraf compared with a standard Advagraf-based immunosuppressive regimen in de novo renal transplantation. Non inferiority will be assessed by a combined study endpoint consisting of the development of biopsy-proven rejection of BANFF class Ia or higher and/or graft loss and/or patient death within the first six months after renal transplantation.
