What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

Summary

This early-stage trial at the Cleveland Clinic is studying how a specific type of hyaluronic acid (HA35) affects muscle protein in 24 healthy adults. Participants take either HA35 or a placebo capsule for three days, then undergo tests including muscle biopsies and a gut permeability test. The goal is to understand the basic mechanisms, not to treat any disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Sodium hyaluronate (HA35)
What this could lead to
If successful, this could help scientists understand how HA35 affects muscle health, possibly pointing toward future treatments for muscle loss.
What could go wrong
This is a very early, small study in healthy people, not patients. It only tests short-term effects and may not lead to any treatment.
