About this study

Official title: Autologous Bone Marrow-derived Mononuclear Cells for Therapeutic Arteriogenesis in Patients With Limb Ischemia A Double Blind, Placebo Controlled, Study in Diabetic and Non-diabetic Patients

The investigators propose confirm and extend the findings of open studies on the apparent efficacy of bone-marrow derived mononuclear cells for the induction of arteriogenesis in patients with severe claudication or critical leg ischemia and pay special attention to the influence of diabetic disease on the outcome of the study and to the possible pro-atherogenic/ pro-inflammatory effects of BM-MNC injections.

Read the detailed description

Although the safety and beneficial effects of intramuscular transplantation of bone marrow derived mononuclear cells procedure appear well documented, a number of critical question regarding application of BM-MNC for peripheral vascular disease remain to be answered. First, although the original study has been partially performed as semi-blinded study (patients with double sided claudication were recruited and blindly treated with BM-MNC in one leg and peripheral blood injections in the other leg), this approach does exclude a placebo effect. Second, although patients with mild diabetes were included in the protocol, the results for diabetic patients were not analyzed separately. Diabetic disease is characterized by monocyte and endothelial progenitor cell dysfunction and it is still unclear whether this approach is also effective in diabetic patients. Third, although six-month results are reported long-term efficacy has not been established yet.

To address these issues, the investigators now propose confirm and extend the findings from open studies in a randomized double-blind study in patients with severe claudication or critical leg ischemia and pay special attention to the influence of diabetic disease on the outcome of the study and to the possible pro-atherogenic/ pro-inflammatory effects of BM-MNC injections.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing bone marrow derived mononuclear cells in people with Intermittent Claudication and Peripheral Vascular Diseases, run by Leiden University Medical Center at 1 site in Netherlands.

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 5 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 6 Jul 2011. 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 Netherlands. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Jan HN Lindeman, MD, PhD (#31 (0)71 5263968, Lindeman@lumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Limb salvage/wound healing at t=6 months; Pain free walking distance (time frame: 6 months). 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 NCT00539266, which also lists 2 linked publications.

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 6 Jul 2011.
