Brief Summary:
This study is designed to evaluate the efficacy and safety of ixmyelocel-T, a patient-specific expanded multicellular therapy, for the treatment of patients with critical limb ischemia (CLI). The study is a randomized, vehicle controlled (placebo)study in CLI patients who have no option for revascularization procedures. All patients randomized will undergo a small volume bone marrow aspiration in a 15-minute outpatient or in-office procedure. All patients will receive injections of either ixmyelocel-T or vehicle-control into their pre-identified index leg. Patients will be followed for 18 months.

Condition or disease Intervention/treatment Phase
Critical Limb Ischemia Biological: Ixmyelocel-T Other: Placebo Phase 3

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 41 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study To Evaluate The Efficacy, Safety, And Tolerability Of Ixmyelocel-T In Subjects With Critical Limb Ischemia And No Options For Revascularization
Study Start Date : February 2012
Actual Primary Completion Date : April 2014
Actual Study Completion Date : April 2014

Arm Intervention/treatment
Experimental: ixmyelocel-T Biological: Ixmyelocel-T
On Day 14, 20 intramuscular injections of ixmyelocel-T on pre-identified index leg.

Placebo Comparator: Placebo Other: Placebo
On Day 14, 20 intramuscular injections of vehicle control on pre-identified index leg.

Primary Outcome Measures :
  1. Amputation free survival (AFS) at 12 months post-injection [ Time Frame: 12 months ]
    The primary objective will be to assess the efficacy of ixmyelocel-T compared to placebo (vehicle control) on AFS at 12 months post-injection in CLI patients with no options for revascularization. Amputation free survival is defined as time to the first occurrence of either major amputation (above the talus) in the index leg or all-cause mortality (death).

Secondary Outcome Measures :
  1. Percent of patients with adverse events [ Time Frame: 18 months ]
    A secondary objective will be to evaluate the overall safety and tolerability of ixmyelocel-T versus placebo in patients with CLI from time of aspiration through 18 months post-treatment/follow-up by % of patients with adverse events.

  2. Percent of patients with complete wound closure by Month 12 [ Time Frame: 12 months ]
    A secondary objective is to assess the percent of patients with at least 1 ischemic wound on the index leg that is present at Visit 3 (preinjection) having complete closure by Month 12.

  3. Percent of patients experiencing a major cardiac event (MACE) by Months 6, 12, and 18 [ Time Frame: 6, 12 and 18 months ]
    % of patients experiencing a MACE event defined as cardiovascular mortality, myocardial infarction, chest pain requiring hospitalization, or stroke.

Ages Eligible for Study:   35 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males and nonpregnant, nonlactating females
  • Ages 35 to 90 years of age
  • Diagnosis of CLI with tissue loss (corresponding to Rutherford Category 5; see Appendix B) having an ulcer size of at least 0.5 cm2, a smaller sized ulcer penetrating into the subcutaneous tissue, and/or gangrene (dry). In addition, the subject must have ONE of the following documented at screening:

    • Ankle systolic pressure < 70 mm Hg
    • Toe systolic pressure < 50 mm Hg
    • TcPO2 < 30 mm Hg (in a supine position)
  • Subjects must have no reasonable standard-of-care options for surgical or endovascular revascularization interventions
  • Subjects must have the following:

    • A narrative documenting the reasons why the site vascular specialist considers the subject "no option". A vascular specialist will be the principal investigator (PI) or subinvestigator and is defined as: vascular surgeon, interventional cardiologist, certified vascular medicine specialist, or interventional radiologist; AND
    • Secondary confirmation by an independent Eligibility Review Committee (ERC; see Section 8.1) after review of appropriate documents including, but not limited to: imaging results, medical records, surgical history, site vascular specialist narrative documenting reasons for "no option," and/or lab reports.
  • Major amputation in the index leg or death is not anticipated within 3 months of screening in the opinion of the vascular specialist (who must be the PI or subinvestigator)
  • In the opinion of the investigator, the subject is controlled on medical therapy indicated for CLI (unless there is a documented contraindication or intolerance)
  • Subject is current with all age-appropriate American Cancer Society (ACS) or similar (e.g., United States Preventative Service Task Force) screening guidelines
  • Given medical history and concurrent medication, the subject is an acceptable candidate for bone marrow aspiration and intramuscular injection procedures in the opinion of the Investigator
  • Subject is willing and able to comply with the scheduled visits, aspiration/injection procedure, wound care instructions treatment plan, and other study procedures for the duration of the study
  • Provide a personally-signed and dated informed consent document indicating that the subject (or a legally-acceptable representative, if permitted by the site's Investigational Review Board [IRB]) has been informed of all pertinent aspects of the study
