This is a multi-centre, open label, dose escalation study to assess the safety, tolerability and efficacy of two infusions of CYP-001, in adults who have steroid-resistant GvHD.
This is a multi-centre, open label, dose escalation study to assess the safety, tolerability and efficacy of two infusions of CYP-001, in adults who have steroid-resistant GvHD.
Participants will receive standard of care treatment throughout the study, according to local procedures. The first eight participants will be enrolled in Cohort A and receive a CYP-001 dose of 1 million cells per kg, up to a maximum dose of 100 million cells, on Day 0 and Day 7. Subject to a safety review of data from Cohort A, an additional eight participants will be enrolled into Cohort B and receive a CYP-001 dose of 2 million cells/kg, up to a maximum dose of 200 million cells, on Day 0 and Day 7. The primary evaluation period concludes for each participant 100 days after the first dose of CYP-001. Participants will have study visits on Days 0, 3, 7, 14, 21, 28, 60 and 100. Subsequently, participants will enter a long term follow-up period, which concludes 2 years after the first dose of CYP-001. |

| Description |
A connective tissue cell that normally gives rise to other cells that are organized as three-dimensional masses. In humans, this cell type is CD73-positive, CD90-positive, CD105-positive, CD45-negative, CD34-negative, and MHCII-negative. They may further differentiate into osteoblasts, adipocytes, myocytes, neurons, or chondroblasts in vitro. Originally described as residing in the bone marrow, this cell type is now known to reside in many, if not all, adult organs.; Many but not all mesenchymal cells derive from the mesoderm. MSCs are reportedly CD3-negative, CD4-negative, CD5-negative, CD8-negative, CD11a-negative, CD11b-negative, CD14-negative, CD19-negative, CD29-positive, CD31-negative, CD34-negative, CD38-negative, CD40-negative, CD44-positive, CD45-negative, CD49-positive, CD54-positive, CD66b-negative, CD79a-negative, CD80-negative, CD102-positive, CD106-positive, CD117-positive, CD121a-positive, CD121b-positive, CD123-positive, CD124-positive, CD133-negative, CD146-positive, CD166-positive, CD271-positive, B220-negative, Gr1-negative, MHCI-positive, MHCII-negative, SSEA4-negative, sca1-positive, Ter119-negative, and glycophorin A-negative. Cultured MSCs are capable of producing stem cell factor, IL7, IL8, IL11, TGF-beta, cofilin, galectin-1, laminin-receptor 1, cyclophilin A, and MMP-2. |
