Summary

This trial tests whether a person's own stem cells, taken from fat tissue and given back through an IV, can safely improve quality of life and physical function in people with aging frailty. The study plans to enroll 200 adults aged 40 to 90 who have lost energy and exercise tolerance. The trial is currently suspended, so results are not yet available.

What this could mean

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

Active substance
autologous stem/stromal cells from fat tissue
What this could lead to
If it works, this could point toward a treatment to improve mobility and energy in frail older adults.
What could go wrong
This is an early, suspended trial with no phase, so results are uncertain. Risks include side effects from the cell infusion procedure.
