Study Summary

This trial will test injections of volar fibroblasts to improve skin firmness for amputees. Participants will be randomly assigned to receive injections or a placebo. Monitored for 3 months.

Who is the study for?
Adults aged 18-75 with a below-the-knee amputation who use a prosthetic leg can join this trial. They must have healthy skin on the limb, not be pregnant or breastfeeding, and agree to contraception during the study. Smokers, those with certain skin diseases, active infections, bleeding disorders or taking immunosuppressants are excluded.Check my eligibility
What is being tested?
The trial is testing injections of volar fibroblasts (cells from one's own body) into the residual limbs of amputees to see if it makes their skin firmer compared to a control group receiving a placebo. Participants will be followed for up to three months after treatment.See study design
What are the potential side effects?
Potential side effects may include complications at injection sites such as pain or infection, allergic reactions to materials used in the procedure, and general discomfort from biopsy and tattooing required for cell harvesting and site marking.
