From Bench to Bedside – ongoing Clinical Development in Organoids and cell Therapy in Europe
Background & Aim
Two case studies are used to demonstrate the path of clinical development and translation into practice on the European market. Two product developments are presented that are characterised by high patient benefit.
ATORM-C is an organoid-based therapy for the treatment of chronic inflammatory bowel diseases (IBD). ATORM-C is classified in Europe as a Tissue Engineered Product (TEP) under the ATMP regulations. The active ingredient of ATORM-C is autologous intestinal organoids derived from adult stem cells cultured in vitro. The ability of stem cells to grow into the organ or tissue enables ATORM-C to develop its therapeutic efficacy through tissue regeneration. The therapeutic efficacy of ATORM-C has been investigated in small and medium to large animal models. The first patients were treated in South Korea.
Methodology
Current treatment strategies for chronic IBD are aimed at limiting the excessive immune response. However, this strategy is not suitable for reversing the cellular changes that underlie the development of the disease.
It is planned to establish GMP-compliant production of the organoids in Germany. Clinical testing of the product is planned from 2026. The aim is to obtain marketing authorisation for ATORM-C in Europe.
Results
The product MesemCart is an ATMP for the treatment of cartilage damage to the knee joint. The active ingredient is mesenchymal stromal cells derived from human umbilical cord tissue (UC-MSC). MesemCart is intended for allogeneic use. The cell suspension is delivered to the surgeon off the shelf in a defined quality together with a collagen matrix. The cell-laden matrix is applied to the cartilage damage and fixed with fibrin glue or sutures intraoperatively during arthroscopy of the knee joint. Treatment with the UC-MSC aims to modulate inflammation, relieve pain and prevent further damage as well as regenerate hyaline cartilage.
MesemCart is intended for the following indications: symptomatic grade III/IV cartilage defects according to the International Cartilage Repair Society (ICRS), osteochondral defects with a maximum depth of 3 mm, focal cartilage defects with a defect size of 1 to 6 sq cm. The application for a clinical trial in Europe has been submitted. In the Phase I/II clinical trial, safety as the primary endpoint and efficacy as the secondary endpoint will be tested in 55 patients.
Conclusion
MesemCart will be the first allogeneic cell therapy based on UC-MSC for the treatment of cartilage damage to the knee joint in Europe.
期刊介绍:
The journal brings readers the latest developments in the fast moving field of cellular therapy in man. This includes cell therapy for cancer, immune disorders, inherited diseases, tissue repair and regenerative medicine. The journal covers the science, translational development and treatment with variety of cell types including hematopoietic stem cells, immune cells (dendritic cells, NK, cells, T cells, antigen presenting cells) mesenchymal stromal cells, adipose cells, nerve, muscle, vascular and endothelial cells, and induced pluripotential stem cells. We also welcome manuscripts on subcellular derivatives such as exosomes. A specific focus is on translational research that brings cell therapy to the clinic. Cytotherapy publishes original papers, reviews, position papers editorials, commentaries and letters to the editor. We welcome "Protocols in Cytotherapy" bringing standard operating procedure for production specific cell types for clinical use within the reach of the readership.
