This study will determine the safety of allogeneic stem cell therapy from healthy donors, for 2nd degree burn wounds of less than 20% Total Body Surface Area (TBSA), at four different dose levels. Clinical evaluation will take place every 1 to 4 weeks intervals until wound closure, and then monthly for 6 months following the last administration of MSCs. Once the safety and dose-response analysis in Phase 1 is completed, an expanded trial will be initiated to better examine the efficacy of MSC therapy in 2nd degree burn wounds. Phase 1 will establish the maximum safe dose that will be used in the Phase II trial.
Full Title of Study: “A Pilot Safety Study of the Administration of Mesenchymal Stem Cells (MSC) in the Treatment of Burn Wounds”
- Study Type: Interventional
- Study Design
- Allocation: N/A
- Intervention Model: Single Group Assignment
- Primary Purpose: Health Services Research
- Masking: None (Open Label)
- Study Primary Completion Date: March 18, 2019
- Biological: Allogeneic (MSC’s) Application to the Burn Wounds
- Allogeneic (MSC’s) Application to the Burn Wounds. The first group of 5 will be started on the lowest dose. If there are no adverse reactions, the second group of 5 will receive a higher dose. This will be repeated for the third and fourth groups with each receiving a higher dose Initial dose level will be 2.5 x 10³ Allogeneic MSCs cells/square cm. Second dose level 5 X 10³ Allogeneic MSCs cells/square cm. Third dose level 1 X 10⁴ Allogeneic MSCs cells/square cm. Fourth dose level 2 X 10⁴ Allogeneic MSCs cells/square cm. Up to 2 administrations of cells will be allowed per dose level to be given over a period of no more than 8 weeks. Each administration of cells will be no less than ten days apart and no more than 6 weeks apart.
Arms, Groups and Cohorts
- Experimental: Allogeneic (MSC’s) Application to the Burn Wounds
- Allogeneic (MSC’s) Application to the Burn Wounds. The 1st group of 5 will be started on the lowest dose. If there are no adverse reactions, the 2nd group of 5 will receive a higher dose. This will be repeated for the 3rd and 4th groups with each receiving a higher dose. Up to 2 administrations of cells per dose level to be given over a period of no more than 8 weeks. Each administration of cells will be no less than ten days apart and no more than 6 weeks apart.
Clinical Trial Outcome Measures
- Monitoring for adverse events as Assessed by CTCAE v4.0 following administration of allogeneic MSCs to 2nd degree burn wounds.
- Time Frame: 1.5 years
- The study will consist of a dose escalation phase consisting of four dose levels. Each dose level will compare the safety of administering allogeneic MSCs, with 5 patients per group.
