Brief Summary:
Evaluate the feasibility of an autologous cell preparation composed of a mixture of cells enriched for endothelial progenitor cells (EnEPCs) and multipotent adult hematopoietic stem/progenitor cells (HSPC) (BGC101), in the treatment of patients suffering from peripheral arterial disease (PAD) with critical limb ischemia (CLI) who have not responded to optimal pharmacological treatment or control of risk factors and/or had a revascularization failure, and do not have the option of further revascularization treatment.

Condition or disease Intervention/treatment Phase
Critical Limb Ischemia Peripheral Arterial Disease Peripheral Vascular Disease Biological: BGC101 (autologous EnEPC preparation) Biological: Control medium Phase 1 Phase 2

Detailed Description:

BGC101 is designed to treat peripheral vascular disease in patients suffering from Critical Leg Ischemia (CLI) also referred to as chronic limb threatening ischemia (CLTI).

This part of the study is designed as a placebo double-blind randomized controlled trial (CRT) assessing the safety and efficacy of BGC101 in 45 eligible subjects in 2 Arms: Arm A: BGC101 treatment and Arm B: Placebo treatment. The Arm A:Arm B ratio is 2:1 A single dose treatment of the personalized cells by intramuscular injections into the affected leg takes less than 10 minutes.

Cells from a standard blood draw (with no pre-treatment, bone marrow aspiration, mobilization or apheresis) are transformed, within a day, into the investigational medicinal product BGC101.

BGC101, intended for autologous use, is a 'ready-to-use' cell suspension in prefilled syringes.

Primary Outcome Measures :
  1. Safety (Incidence of adverse events) [ Time Frame: 12 Months ]
    • Incidence and proportion of incidence between treatment arms of adverse events of specific interest (AESI) and injection-related AE
    • Incidence of serious adverse events (SAEs) including SAEs related or probably related to the treatment
    • Vital signs, physical examination, and electrocardiogram (ECG)
    • Safety laboratory values of hematology, blood chemistry, and urinalysis
    • Local tolerability (injection site reaction)

  2. Efficacy (Improvement of indication signs) [ Time Frame: 12 Months ]
    • Major amputation (below or above the knee) rate at Month 12
    • Major amputation-free survival (AFS) rate at Month 12

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria:

  1. Have the time and ability to complete the study and comply with instructions.
  2. Capable of understanding of the purpose of the study and the contents of the informed consent form.
  3. Aged at least 18 years.
  4. Non-pregnant and non-lactating female patients.
  5. Have the clinical indications diagnostic of CLI based on Rutherford category 4-5
  6. Have at least one of the hemodynamic indicators of severe peripheral arterial occlusive disease (WIfI ischemia grade 2):

    • Toe pressure < 40 mmHg
    • Ankle pressure < 70 mmHg
    • TcPO2 < 40mmHg
  7. Meeting one of the following conditions:

    1. Poor candidate for standard revascularization treatment for peripheral arterial disease due to unfavorable anatomy or high surgical/intervention risk based on the patient's underlying comorbidities.
    2. After undergoing clinically ineffective revascularization. Six weeks or more after undergoing a prior index limb revascularization the patient demonstrates:

      • No improvement in clinical signs and symptoms of CLI as evidenced by lack of improvement in rest pain (when not under increased pain relief) and/or inadequate wound healing or progression of tissue loss despite adequate standard treatment.
      • Ongoing ischemia as defined above in the criterion 6.
      • The patient is no longer amenable to further interventional or surgical revascularization (see inclusion criterion 7).

Exclusion criteria:

  1. Severe and uncorrected aorto-iliac and/or common femoral artery disease, i.e. absence of femoral pulse or monophasic common femoral artery doppler waveform.
  2. Concurrent therapy that, in the Investigator's opinion, would interfere with the evaluation of the feasibility of the study medication.
  3. Treatment with any investigational product within the last 6 months or enrollment in any active study involving the use of investigational devices or drugs.
  4. Presence of any other condition or circumstance that, in the judgment of the investigator, might negatively impact the outcomes of the treatment under investigation.
  5. Prognosis of a major amputation (below or above the knee), within 4 weeks after screening.
  6. Severe wound (WIfI wound grade 2 or 3).
  7. Significant ongoing infection (WIfI infection grade 2 or 3).
  8. Relative or absolute contraindications for intramuscular injections at the intended treatment site, in cases such as severe skin lesions, severe edema or morbid obesity, based on clinician opinion.
