Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Diagnosis of Critical Limb Ischemia per protocol (see diagnostic criteria #2) with regard to the study limb.

  • There is no reasonable open surgical or endovascular revascularization option as determined by the treating vascular specialist. Factors that may contribute to the determination of inoperability may include:
  • Anatomical considerations
  • No outflow targets
  • No appropriate conduit (i.e. vein for bypass)
  • Long segment occlusions or calcified lesions that predict poor outcome with endovascular approaches.
  • High risk medical conditions
  • Unstable cardiac disease.
  • Renal insufficiency
  • History of prior failed revascularization attempts
  • The patient's unsuitability must be confirmed by 2 qualified physicians.
  • The attending vascular surgeon will provide the primary assessment.
  • The confirmatory opinion must come from a fully licensed physician. (not a resident)
  • If anatomical considerations are invoked, the second physician may be a vascular surgeon, interventional radiologist, cardiologist, or vascular medicine specialist.
  • If medical co-morbidity is deemed the high risk aspect, then the confirmatory opinion may be obtained from an internist, family physician, cardiologist, vascular medicine, nephrologists, or vascular surgeon.
  • Age >18 years and ability to understand the planned treatment
  • Subject has read and signed the IRB/IEC approved Informed Consent form
  • Patients for whom the following medication(s) is prescribed must have a one month stable baseline of appropriate/maximally tolerated therapy prior to enrollment: Plavix/asprin therapy, anticoagulation therapy, cholesterol lowering agent, and or blood pressure medication
  • Hematocrit ≥ 28.0%, White Blood Cell count ≤ 14,000, Platelet count ≥ 50,000, INR ≤ 1.6 unless on Coumadin, or PTT <1.5 x control (to avoid bleeding complications) Patients on Coumadin will be corrected prior to the procedure and must have an INR<1.6 at the time of randomization/surgery.

Who cannot join

  • Life expectancy <6 months due to concomitant illnesses
  • History of bone marrow diseases (especially NHL, MDS) that prohibit transplantation
  • Terminal renal failure with existing dependence on dialysis
  • Known active malignancy or results outside of normal limits from the following tests: PAP, Chest X-ray, PSA, Mammogram, Hemocult unless follow-up studies reveal patient to be cancer free..
  • Poorly controlled diabetes mellitus (HgbA1C>10%)
  • Medical risk that precludes anesthesia (conscious sedation), or ASA Class 5
Show all 13Show fewer
  • Life-threatening complications of the ischemia necessitating immediate amputation
  • Uncorrected iliac artery occlusion on index side
  • Extensive necrosis of the index limb or other conditions that make amputation inevitable (Rutherford Category 6)
  • Active clinical infection being treated by antibiotics within one week of enrollment
  • Treatment with immunosuppressant drugs (including Prednisone > 5 mg per day).
  • Female who is pregnant or nursing, or of child bearing potential and is not using a reliable birth control method.
  • Underwent a major cardiovascular surgical procedure (carotid endarterectomy, open arterial aneurysm or bypass surgery, or coronary artery bypass surgery) or an adverse cardiovascular event (stroke or MI) within the 30 days prior to randomization

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing centrifuge, laboratory, tabletop (SmartPReP2 BMAC System) in people with Arterial Occlusive Diseases, run by Harvest Technologies 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 24 inclusion and 13 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 9 Mar 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 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?

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?

avoid amputation (time frame: 60 days). 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 9 Mar 2012.
