Key requirements
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 45 to 99 years
- All sexes
- Adult, Older adult
Who may be able to join
- Adult male or female subjects between ages 45 to 99 years of age at the time of screening.
- Subjects with a diagnosis of PAD due to atherosclerosis at the stage of CLI, with minor tissue loss up to the ankle level (ulcer/s and/or necrosis).
- Ankle pressure (AP) ≤70 mmHg or toe pressure (TP) ≤50 mmHg in the index leg or transcutaneous oxygen pressure (TcPO2) ≤30 mmHg.
- Subject unsuitable for revascularization (by any method) in the index leg based on unfavorable risk-benefit assessment of the physician investigator. Unsuitability to revascularization should be based on any of the following:
- Anatomic considerations as: inappropriate target artery, diffuse/extensive tibial and/or peroneal artery lesions, inadequate distal run-off.
- Technical considerations as: inappropriate bypass conduit, failed recent revascularization.

- Medical considerations: subject's comorbidities.
- Signed informed consent form.
- Subjects are not eligible for the ongoing phase III study with PLX-PAD in CLI (PLX-CLI-03) due to at least one of the following criteria:
- Evidence of active localized osteomyelitis secondary to contiguous focus of infection, unless amputation is expected within 1 month post PLX-PAD administration. In case of osteomyelitis, patients must be treated with antibiotics during screening and PLX-PAD administration or as long as there is evidence of active infection.
- Subject on renal replacement therapy or with eGFR <15 mL/min.
- Current treatment with high dose systemic steroids (prednisone equivalent >7.5 mg/day) or topical steroids on the index leg.
- History of autologous bone marrow transplantation (if not due to hematologic malignancy) or solid organ transplantation, clinically stable.
- Immunocompromised subjects due to disease for any reason, including immunosuppressive therapy, at screening (for steroid therapy, refer to the criterion c)
- CLI with major tissue loss (Rutherford Category 6) in the contralateral leg.
- Diabetes mellitus with glycosylated hemoglobin (HbA1c) >10% at Screening.
- HIV controlled by antiretroviral therapy
- Past drug or alcohol abuse. Known history of cancer is eligible if occurred beyond 2 years before screening
Who cannot join
- Non-atherosclerotic PAD and vasculitis (e.g., Buerger's disease [thromboangiitis obliterans], Takayasu's arteritis, etc.).
- CLI with major tissue loss (Rutherford Category 6) in the index leg. Ulcers from venous or neuropathic origin if not associated with at least one ulcer from arterial origin.
- Evidence of active infection in either leg (e.g., cellulitis, myositis) except localized osteomyelitis secondary to contiguous focus of infection, under antibiotic treatment.
- Subject having undergone surgical/endovascular revascularization or major/minor amputation, in either leg, less than 1 month prior to Screening.
- Planned or potential need for major/minor amputation or any revascularization of either leg within 1 month of EAP entry upon physician's judgment.
- Aortoiliac stenosis or common femoral artery stenosis ≥70%, or otherwise suspicion of inadequate inflow to the index leg at the time of Screening.

- Exposure to allogeneic cell based therapy in the past or exposure to autologous cell therapy in the last 12 months before screening.
- Known allergies to any of the following: dimethyl sulfoxide (DMSO), human serum albumin, bovine serum albumin.
- History of allergic/hypersensitivity reaction to any substance having required hospitalization and/or treatment with intravenous steroids/epinephrine, known allergy to more than 3 allergens, or in the opinion of the Physician the subject is at high risk of developing severe allergic/hypersensitivity reactions.
- History of severe atopic disease (including but not limited to chronic urticaria, respiratory allergy requiring oral steroids), or history of uncontrolled Asthma (Global Initiative for Asthma [GINA] III-IV).

About this study
Official title: Expanded Access to Provide Intramuscular Injections of PLX-PAD for the Treatment of Subjects With Critical Limb Ischemia (CLI) With Minor Tissue Loss Who Are Unsuitable for Revascularization
This is an Expanded Access program (EAP), sponsored by WideTrial for the treatment of critical limb ischemia (CLI).
Widetrial, an Expanded Access specialist, has arranged to supply participating sites with PLX-PAD for CLI patients who cannot participate in the ongoing research trial and who seek exploratory treatment options. This program includes FDA-authorized cost recovery, meaning payment is required to cover a portion of the costs of delivering product and complying with regulatory obligations.
