Study Summary

This trial is testing whether injecting skin cells from the palm or sole can thicken the skin layer at the site of an amputation below the knee, in order to improve healing.

Who is the study for?
This trial is for adults aged 18-65 with below-knee amputations who use a prosthetic. Women must not be pregnant, breastfeeding, or planning to become pregnant and agree to contraception. Excluded are those with deep skin erosions, certain medical conditions (like autoimmune diseases), allergies to study materials, active infections, recent neuromas, or on immunosuppressives.Check my eligibility
What is being tested?
The trial tests autologous volar fibroblast injections versus placebo in thickening the stump's skin layer for amputees. Participants will receive either their own cultured skin cells or a placebo injected into the stump site at Johns Hopkins.See study design
What are the potential side effects?
Potential side effects may include local reactions at the injection site such as pain, redness, swelling; risk of infection; allergic reactions to components used during treatment; and possible systemic responses like fever.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Autologous skin fibroblastsExperimental Treatment1 Intervention
For whole stump participants: The investigators will be comparing whole stump injection sites that receive autologous skin fibroblasts to vehicle (placebo) injections. This subject receives autologous skin fibroblast whole stump injections. For localized injection participants: The investigators are comparing two injection sites in the same individual. This site receives autologous skin fibroblasts.
Group II: ControlPlacebo Group1 Intervention
For whole stump participants: The investigators will be comparing whole stump injection sites that receive autologous skin fibroblasts to vehicle (placebo) injections. This subject receives vehicle (placebo) whole stump injections. For localized injection participants: The investigators are comparing two injection sites in the same individual. This site receives a placebo.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is this trial enrolling participants currently?

"According to the clinicaltrials.gov data, this experiment is still seeking participants and has been open since September 5th 2019, with its last revision on June 8th 2022."

Answered by AI

Has the FDA provided clearance for Autologous Skin Fibroblasts?

"As this is a Phase 2 trial, the safety of Autologous Skin Fibroblasts has been provisionally evaluated at a score of two due to limited evidence on efficacy."

Answered by AI

Are participants who are of an advanced age being enrolled in this research?

"This clinical trial outlines that patients aged 18 to 65 are eligible for inclusion. For those younger than 18 and older than 65, there exists 3 other trials tailored towards their age ranges."

Answered by AI
