Is this trial a fit for you?

Likely a good fit

Adults with kidney failure who are receiving hemodialysis or peritoneal dialysis, not taking ergothioneine supplements, and without a blood transfusion in the prior 90 days are ideal candidates.

Probably not a fit

People not on dialysis, those already taking ergothioneine supplements, or those who had a blood transfusion within 90 days are unlikely to benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

People with kidney failure who receive hemodialysis or peritoneal dialysis will be enrolled and given either a daily ergothioneine supplement or a matching placebo. Blood ergothioneine levels will be measured over the treatment period to see whether supplementation replenishes circulating levels. Participants who recently had a blood transfusion or who already take ergothioneine-containing supplements are excluded. The intervention is administered at a single site in Palo Alto, and safety and tolerability will also be monitored.

Why it matters

Potential benefit: If successful, the supplement could restore ergothioneine levels in dialysis patients, which might help protect cells from oxidative damage and related complications.

How similar studies have gone: Ergothioneine supplementation is a relatively novel approach with limited clinical trial data in dialysis patients, though preclinical and observational studies suggest possible antioxidant benefits.
