Study of Sulphoraphane in Chronic Kidney Disease

August 8, 2024 updated by: Thu Le, University of Rochester

Safety, Feasibility and Efficacy of Sulforaphane (Avmacol) in Chronic Kidney Disease

The purpose of this study is to test the safety of the compound sulforaphane that boosts the activity of antioxidant genes in the body to combat oxidative stress. Oxidative stress has been shown experimentally to play a role in kidney disease. This drug has been tested in patients with breast cancer who have normal kidney function, but has never been tested in patients with kidney disease.

In this study, the investigators will establish a safe dose for patients with chronic kidney disease based on blood levels achieved in patients with normal kidney function.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

We hypothesize that daily intake of sulforaphane (Avmacol Extra Strength (ES)) can decrease kidney disease progression rate and decrease markers of oxidative stress and inflammation in chronic kidney disease (CKD) patients. To test our hypothesis, we will first perform a randomized, Phase 1 clinical trial in a single center funded by an R01 NIDDK award. This is an interventional pharmacokinetic trial, with subjects randomized to different doses of Avmacol ES.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
