入选标准

  • Inclusion Criteria:
  • Males or non-pregnant, non-lactating females.
  • Age 18 or greater at the time of informed consent.
  • Able and willing to provide written informed consent.
  • Type 1 or Type 2 diabetes.
  • Chronic DFU as the index ulcer meeting all of the following criteria:
  • present for at least 4 weeks at the time of Screening Visit 1
  • located below the malleoli of the foot
  • extends to the dermis or subcutaneous tissue, surrounded by healthy skin, without evidence of exposed muscle, tendon, bone, or joint capsule
  • area measures 1 to 10 cm2 inclusive, at Screening Visit 1, and
  • non-healing (defined as ≤50% reduction in ulcer size by the Baseline Visit, as compared to Screening Visit 1).
  • Negative for antibodies to HLA Class I molecules expressed on Corlicyte MSCs, as measured by Luminex HLA single antigen beads, within 3 months prior to start of Treatment Phase without interval sensitizing events.
  • For an index ulcer on the plantar surface of the foot, willingness to offload the foot per study protocol.
  • In women of childbearing potential, willingness to use effective means of birth control during the course of the study; if using systemic birth control, this must have been used for 6 months or longer prior to Screening Visit 1.

排除标准

  • Exclusion Criteria:
  • Planned DFU treatment to the index ulcer that includes enzymatic agents, cytotoxic agents or any substance(s) that would affect MSC survival during the study period.
  • Women planning to become pregnant during the course of the study.
  • Significant history of, or current evidence of a severe comorbid medical or psychiatric condition such as liver disease, end-stage renal disease, untreated proliferative retinopathy, bleeding diathesis, schizophrenia, or laboratory abnormality that, in the opinion of the Investigator, would preclude enrollment because of unacceptable risk.
  • Presence of any skin condition or skin disorder around the index ulcer that might interfere with the diagnosis of or assessment of study-related endpoints, such as atopic dermatitis, eczema, psoriasis, or seborrheic dermatitis.
  • Presence of actinic keratosis or skin cancer within 2 cm of the index ulcer.
  • Cellulitis or other active infection of the index ulcer or any non-index ulcer at Screening.
  • Use of an investigational agent for ulcer care within 30 days prior to Screening Visit
  • Receipt of an investigational agent or device not approved by the US FDA for marketed use in any indication within 30 days prior to Screening Visit
  • Planned participation in another therapeutic study for any indication prior to completion of study participation.
  • Unwillingness or inability to comply with study visits and study procedures for the entire duration of study participation.
  • Known positivity for Human Immunodeficiency Virus (HIV).
  • Active osteomyelitis or gangrene of either foot at Screening.
  • Known Methicillin-resistant Staphylococcus aureus (MRSA) infection within 30 days prior to Screening Visit
  • Poorly-controlled diabetes mellitus, defined as hemoglobin A1c (HbA1c) >12%.
  • Unsuitable for cellular therapy for any reason, in the opinion of the Investigator.
  • Planned use of cell therapy or amniotic membrane treatment for the index ulcer during study participation.
  • Significant titer of antibodies to HLA Class I molecules expressed on Corlicyte MSCs, as measured by Luminex HLA single antigen beads.
  • Presence of severe peripheral artery disease (PAD) defined as clinical evidence of critical limb ischemia (CLI) during Screening.
