CHAMP Trial Summary

This trial will test whether injecting stem cells above and below the point of amputation can prevent ischemic wound complications and further amputations.

Who is the study for?
This trial is for adults aged 40-90 facing lower limb amputation due to severe artery disease. They must be able to have surgery within 30 days and not be on immunosuppressants, HIV positive, or involved in other trials that affect results. Women who can bear children should use birth control during the study.Check my eligibility
What is being tested?
The trial tests if injecting mesenchymal stem cells into muscles around the amputation site can reduce wound issues and further amputations. Control groups won't receive these cells but will undergo standard procedures related to amputation.See study design
What are the potential side effects?
Potential side effects of mesenchymal stem cell injections may include pain at injection site, infection risk, immune system reactions, or tissue swelling. However, specific risks will depend on individual patient factors.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Therapeutic procedure
Secondary outcome measures
Flow Cytometry
Recruitment of proangiogenic hematopoietic cells into sites of ischemia will be measured and reported as assessed by the role of MSCs injected in human skeletal muscle at the time of amputation.

CHAMP Trial Design

5Treatment groups
Experimental Treatment
Active Control
Group I: Active/Treatment GroupExperimental Treatment1 Intervention
Amputation performed at 7 days post allogeneic bone marrow derived mesenchymal stem cell injections.
Group II: Observation Group 3Active Control1 Intervention
Patients undergoing lower extremity bypass grafting procedure. Skeletal muscle samples of the sartorius and anterior tibial muscle will be collected for comparison to treatment group. No study testing, nor follow up visits will occur.
Group III: Control Group 4Active Control1 Intervention
Patients undergoing a standard of care surgical procedure under anesthesia. Core needle biopsies will be collected from the anterior tibial muscle at the time of surgical procedure. No study testing, nor follow up visits will occur.
Group IV: Observation Group 1Active Control1 Intervention
Amputation performed with no MSC administration. Subjects will be followed for incidence of infection and wound healing status to week 24 as a comparator to the Active/Treatment group.
Group V: Observation Group 2Active Control1 Intervention
Tissue Collection Group: Amputation performed with no MSC administration. Subjects will not be followed after amputation is performed. Tissue collection will occur at time of amputation.

Frequently Asked Questions

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

What is the size of the cohort participating in this trial?

"Affirmative. According to the details on clinicaltrials.gov, this medical experiment was initially advertised in January 2017 and has been actively recruiting since then with its most recent update occurring in September 2022. 16 individuals are desired for participation at a single trial site."

Answered by AI

Are applications for this trial still being accepted?

"Affirmative. The information hosted on clinicaltrials.gov suggests that this investigation, which was originally published on the first of January 2017, is presently enrolling individuals. 16 subjects must be recruited from a single location for completion of the trial."

Answered by AI

Is the target demographic for this experiment restricted to individuals over thirty years of age?

"To qualify for this examination, patients must be 40 to 90 years old. Of the total 1210 participants, 76 of them are younger than 18 while 1134 have already exceeded retirement age."

Answered by AI

Who is eligible to register for the research protocol?

"This research is open to 16 individuals between 40 and 90 years old suffering from a vascular disease. Potential candidates must meet certain requirements, such as having ulceration or gangrene distal to their malleoli that allows an approximate 3cm x 10cm x 3 cm area of lower extremity for amputation (as decided by independent specialist). Additionally, the procedure can occur up to 30 days after screening. Moreover, female participants with childbearing potential are expected to utilize contraception during the course of this study; moreover they will be asked to undergo pregnancy tests at enrollment."

Answered by AI

Has the FDA sanctioned Allogeneic bone marrow derived mesenchymal stem cells for therapeutic usage?

"The safety profile of allogeneic bone marrow derived mesenchymal stem cells was estimated at a 1, as it is only in the first phase of clinical trials and there are limited data regarding efficacy or safety."
