Safety, Feasibility and Efficacy of Sulforaphane (Avmacol Extra Strength) in Chronic Kidney Disease - Randomized, Double-blind, Placebo-controlled Trial

Description

The Sulforaphane Production System® in Avmacol Extra Strength (ES) supplies broccoli seed extract (glucoraphanin) and Myrosimax® (Active Myrosinase Enzyme) which helps promote sulforaphane production in your body. The investigators hypothesize that daily intake of Avmacol ES can decrease kidney disease progression rate and decrease markers of oxidative stress and inflammation in Chronic Kidney Disease (CKD) patients. They will test this hypothesis in a randomized, double-blind, placebo controlled Phase 2 clinical trial. This proposed study has been funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), R01 DK128677.The investigators will test the safety and efficacy of Avmacol ES in Chronic Kidney Disease (CKD) patients. After having established a safe dose of 4 tablets once daily in participants with CKD Stages 3 - 4 in the pharmacokinetic (PK) phase, the investigators will enroll 100 participants from the Kidney Clinic at the University of Rochester M

A urine pregnancy test will be completed for individuals of childbearing potential before administering the study drug, and repeated thereafter at every study visit (\~ every 3-4 months) * History of dementia documented in the medical record * On anticoagulants or immunosuppression * Under treatment for cancer * Delayed gastric emptying or similar GI conditions Non-English-speaking individuals are excluded in this randomized phase of the study because the lack of English proficiency will affect a subject's ability to report problems or adverse events. If a patient cannot read, the consent form will be read to them by the research coordinator.
