About this study

Official title: Evaluation the Side Effects of Repeated Bone Marrow Derived Mono Nuclear Stem Cells Transplantation in Patients With Lower Limb Ischemic Ulcer

Critical limb ischemia (CLI) results from severe occlusive disease that impairs distal limb perfusion to the point where oxygen delivery is no longer adequate to meet the metabolic needs of the tissue, even under resting conditions. The limits of peripheral artery disease (PAD) compensatory mechanisms, such as distal vasodilatation and collateral formation, have been exceeded at this point. PAD is a widespread disease, affecting up to 15% of all adults older than 55 years. Formation of true new blood vessels, or angiogenesis, and development of collateral vessels from preexisting blood vessels, or arteriogenesis, is important in the pathophysiology of vascular disease. By stimulating these processes the investigators might be able to provide an alternative treatment strategy for patients with lower limb ischemia. In response to tissue injury and remodeling, neovascularization usually occurs via the proliferation and migration of progenitor endothelial cells (EPC) from preexisting vasculature. Indeed, recent studies have shown that bone-marrow mononuclear cell (BM-MNC) implantation increases collateral vessel formation in patients with limb ischemia. So the investigators determine to evaluate the efficacy of repeated MNC transplantation in patients with ischemic lower limb.

Read the detailed description

In this study we transparent bone marrow derived mononuclear stem cells 4 times to the ischemic limb of 11 patients with PAD.first of all all the patients evaluate by physical examination,PFWD,ABI and serologic tests.then underwent bone marrow aspiration to take sample.In our lab the MNC are separated and divided in to equal doses.one of them inject to the ischemic foot and the othr one are freezed and inject after 3weeks.3 weeks after second injection again patient underwent bone marrow aspiration and the same process repeat.then after 4times transplantation,patients are followed up after 1,3,6,9,12 months after injection and evaluate by physical examination,PFWD,ABI and serologic tests.all the data are collected and analysed and the result will be shown.3 patients underwent cell transplantation just one time due to one time bone marrow aspiration.They are followed up after 1,3,6,9,12 months after injection and evaluate by physical examination,PFWD,ABI and serologic tests.at the end of the study patients with 4imes injection and 1time injection will be compared.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. side effects

    evaluation the side effect of cell injection like:allergic reaction,fever,skin eruption,pain increasing,decrease in walking distance,ulcer severity

    Measured: 3months

Secondary outcomes (4)
  1. PFWD

    Evaluation the pain free walking distance after cell transplantation.

    Measured: 3months

  2. ABI

    evaluation the improvement the score of ABI after stem cell transplantation .

    Measured: 3months

  3. size and depth of ulcer

    evaluation the improvement of ulcer by measuring the size and depth of ulcer in millimeter after transplantation.

    Measured: 3months

  4. Amputation

    Evaluation the need of limb amputation because of worsening the ulcer after cell injection.

    Measured: 6months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 4times injection and stem cell transplantation in people with Ischemic Ulcer, run by Royan Institute at 1 site in Iran.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

side effects (time frame: 3months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01480414, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Dec 2012.
