About this study

Official title: A Randomized, Controlled, Parallel Design, Safety and Efficacy Study of Granulocyte Colony Stimulating Factor Mobilized Autologous Peripheral Blood Mononuclear Cell Therapy in Subjects With Diabetic Limb Ischemia.

The purpose of this study is to determine whether the method (implanting stem cells derived from peripheral blood after G-CSF mobilization) of treatment is safe and effective in the management of diabetic foot ischemia, the therapeutic effect of stem cells is caused by improving blood circulation in ischemic limb which would in turn promote ulcer healing, prevent amputation of limb and relieve the Sevier pain of ischemia.

Read the detailed description

One devastating complication of diabetes is peripheral arterial disease (PAD) including critical limb ischemia (CLI), which may result in limb loss. Epidemiological evidence confirms an association between diabetes and increased prevalence of peripheral arterial disease (PAD). The prevalence of peripheral vascular disease among the Indian diabetic population is 13%.

This therapy provides a targeted approach i.e. by improving blood perfusion in the ischemic area of the lower limb by inducing neovascularization, which would be further evaluated by measuring the change in transcutaneous partial pressure of oxygen (TCpO2), NMR angiography of local vessels, ulcer healing, pain relief, limb salvage, ABI index etc.

The specific design of the trial enables us to differentially study the effect of stem cell on diabetic foot CLI as compared to G-CSF (granulocyte colony stimulating factor) in (one control group) and standard therapy (in another control group), this study would also evaluate the effect of stem cell dose.

Extracting stem cells from this method is far more easy to perform as compared to extracting from bone marrow and is less painful for the patient as well.

The yield of mononuclear stem cell from peripheral blood is much higher as compared to bone marrow and role of CD34+ cells in limb ischemia is not yet established in humans, therefore this study would evaluate the dynamics of different types of mononuclear cells and its correlation with the therapeutic effect.

This clinical trial highlights the safety of using G-CSF in diabetic CLI by having a separate control group in which volunteers would be given only G-CSF through subcutaneous route, also this would tell about the therapeutic effect if any attributable to it.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing will receive G-CSF and peripheral blood derived mononuclear cells, G-CSF and Standard Therapy in people with Diabetic Foot and Critical Limb Ischemia, run by Beike Biotech India Pvt.ltd at 1 site in India.

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 12 inclusion and 15 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 17 Jun 2009. 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 India. 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?

Results are not available in the source record.

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

Contact Dr.Kumar Ramsamudara (0091 11 29552056, drkumar@ensindia.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events and laboratory parameters (time frame: 12 Months after the theraphy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Jun 2009.
