Description



Duration of Participation: This is a 16 week study at the University of Colorado Anschutz Medical Campus in Aurora, CO. The study schedule includes: - 2 screening visits - 2 treatment visits per week for up to 8 weeks (16 treatment visits total) - 2 follow-up visits

Age

Adult

Eligibility

Diabetic Foot Ulcer over 18 years old

Detailed Eligibility: Inclusion Criteria: 1. Males or non-pregnant, non-lactating females. 2. Age 18 or greater at the time of informed consent. 3. Able and willing to provide written informed consent. 4. Type 1 or Type 2 diabetes. 5. Chronic DFU as the index ulcer meeting all of the following criteria: a) present for at least 4 weeks at the time of Screening Visit 1 b) located below the malleoli of the foot c) extends to the dermis or subcutaneous tissue, surrounded by healthy skin, without evidence of exposed muscle, tendon, bone, or joint capsule d) area measures 1 to 10 cm2 inclusive, at Screening Visit 1, and e) non-healing (defined as ≤50% reduction in ulcer size by the Baseline Visit, as compared to Screening Visit 1). 6. 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. 7. For an index ulcer on the plantar surface of the foot, willingness to offload the foot per study protocol. 8. 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. Exclusion Criteria: 1. 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. 2. Women planning to become pregnant during the course of the study. 3. 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. 4. 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. 5. Presence of actinic keratosis or skin cancer within 2 cm of the index ulcer. 6. Cellulitis or other active infection of the index ulcer or any non-index ulcer at Screening. 7. Use of an investigational agent for ulcer care within 30 days prior to Screening Visit 1. 8. 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 1. 9. Planned participation in another therapeutic study for any indication prior to completion of study participation. 10. Unwillingness or inability to comply with study visits and study procedures for the entire duration of study participation. 11. Known positivity for Human Immunodeficiency Virus (HIV). 12. Active osteomyelitis or gangrene of either foot at Screening. 13. Known Methicillin-resistant Staphylococcus aureus (MRSA) infection within 30 days prior to Screening Visit 1. 14. Poorly-controlled diabetes mellitus, defined as hemoglobin A1c (HbA1c) >12%. 15. Unsuitable for cellular therapy for any reason, in the opinion of the Investigator. 16. Planned use of cell therapy or amniotic membrane treatment for the index ulcer during study participation. 17. Significant titer of antibodies to HLA Class I molecules expressed on Corlicyte MSCs, as measured by Luminex HLA single antigen beads. 18. Presence of severe peripheral artery disease (PAD) defined as clinical evidence of critical limb ischemia (CLI) during Screening.

Phase

I - Research Studies that focus on the safety of a drug. The goal is to determine the drug's most frequent and serious adverse events and, often, how the drug is broken down and excreted by the body. These studies usually involve a small number of participants.
