This will be a randomized, placebo-controlled, parallel group, multicenter, Phase III study.The study aims to evaluate the Efficacy, Tolerability and Safety of Intramuscular Injections of PLX PAD for the Treatment of Subjects with Critical Limb Ischemia (CLI) with Minor Tissue Loss (Rutherford Category 5) who are Unsuitable for Revascularization.


Critical Limb Ischemia (CLI), Ischemia, PLX-PAD


You can join if…

Open to people ages 45-99

  1. Adult male or female subjects between ages 45-99 years of age.
  2. CLI, with minor tissue loss up to the ankle level (Rutherford Category 5)
  3. Ankle pressure (AP) ≤70 mmHg or TP ≤50 mmHg in the index leg. (If a subject has ABI >1.4 and TP is not measureable, inclusion may be based on TcPO2 ≤30 mmHg)
  4. Subject unsuitable for revascularization (by any method) in the index leg.
  5. Ischemic lesions in the index leg stable for at least 2 weeks.
  6. Ischemic ulcers in the index leg without tendon or bone exposure (unless secondary to a minor amputation).
  7. Under treatment for cardiovascular risk factors: hypertension, hyperlipidemia, diabetes, in accordance with applicable guidelines. Concomitant therapy with a statin and an anti-platelet agent for at least 2 weeks prior to randomization.
  8. Women of childbearing potential must have a negative serum pregnancy test at screening and must be willing to use at least one highly effective birth control method throughout the study.
  9. Subject understood, agreed and provided informed consent. Patients must give written informed consent before any assessment is performed .

  2. CLI with major tissue loss (Rutherford Category 6) in either leg.
  3. Evidence of active infection (e.g., cellulitis, osteomyelitis).
  4. Subject having undergone surgical revascularization or major amputation less than 1 month prior to screening, or endovascular revascularization or minor amputation less than 2 weeks prior to screening.
  5. Planned or potential need for major/minor amputation or any revascularization within 1 month of study entry upon investigator's judgment.
