VALBONNE, France & NANTES, France--(BUSINESS WIRE)--Regulatory News:
TxCell SA (FR0010127662 – TXCL), a biotechnology company developing innovative, personalized cellular immunotherapies using regulatory T cells (Treg) to treat severe chronic inflammatory and autoimmune diseases, and Inserm Transfert, on behalf of Inserm, the Nantes University (Nantes, France) and the Nantes CHU, today announce the signature of an exclusive worldwide licensing agreement.
As per the terms of this agreement, TxCell has been granted an exclusive worldwide license to two patent families filed by the Center for Research in Transplantation and Immunology (CRTI), a center of excellence in the field of transplantation and immunology. The CRTI is a research unit (UMR 1064) affiliated to both Inserm, a French public organization dedicated to human health, and to the Nantes University (Nantes, France).
These patents cover a new type of regulatory T cells (Tregs) that express the CD8 marker. This is opposed to traditionally known Tregs that express CD4 such as the Type 1 Tregs and FoxP3+ Tregs. Specifically, these CD8+ Tregs are non-cytotoxic and display a unique and highly immunosuppressive mechanism of action. This mechanism is mediated through the release of cytokines with anti-inflammatory and tolerogenic (inducing immune tolerance) properties1,2,3,4. As a result, CD8+ Tregs could offer a different and complementary approach to treat inflammatory disorders, including autoimmunity and transplant rejection. In addition, these patents also cover CAR-Treg cells made from these CD8+ Tregs.
The CRTI team, which is led by Ignacio Anegon and Carole Guillonneau, has already demonstrated the efficacy of these CD8+ Treg cell population in several preclinical models of inflammation including heart allograft, human skin transplant rejection and graft-versus-host disease (GvHD) in mice with humanized immune systems. In these models, the administration of CD8+ Treg cells has been shown to prevent the occurrence of skin graft rejection and GvHD, respectively. As per the terms of the agreement announced today, TxCell now has exclusive worldwide rights to both these patent families for all autoimmune diseases and transplantation-related disorders.
"Regulatory T cells are composed of several subpopulations that act through complementary modes of action to prevent or treat inflammatory disorders. TxCell’s unparalleled patent estate is focused on therapeutic Treg cells and already covers type 1 Treg cells and CAR-Treg cells. TxCell, by obtaining an exclusive license on patents covering a new CD8+ Treg cell subpopulation, adds a new pillar to its patent portfolio and further strengthens TxCell’s position as the international Treg leading expert," said Arnaud Foussat, Senior Vice President, Corporate Development and Head of External Collaborations & Alliance Management of TxCell. "This is the fifth academic agreement signed in 2016. Specifically, this license enables TxCell to develop new types of cell therapy products, composed of CD8+ Treg cells, including CAR-CD8+ Tregs, for the treatment of autoimmune diseases as well as transplant-related disorders with high unmet medical need."
"It is a great satisfaction for Inserm Transfert to be involved in such a major technology transfer and to complete it successfully. This license agreement is the first step towards future collaborations with TxCell," said Pascale Augé, President of Board of Inserm Transfert.
Financial terms of the agreement have not been disclosed.

About CRTI – http://www.itun.nantes.inserm.fr/
The Center for Research in Transplantation and Immunology (CRTI) is a research unit (UMR 1064) affiliated to INSERM and Nantes University. The CRTI research programs and organization rely on the definition of common scientific objectives, the development of translational research, sharing of resource, technical platforms development and research development towards clinical and industrial applications.
Main research areas are immunology, transplantation, autoimmune diseases, regenerative medicine and genetics with the aim in the long term of: (i) improving graft survival in transplanted patients thanks to novel biomarkers and immuno-intervention strategies, (ii) implementing these new tools in other clinical conditions such as IMIDs and (iii) developing alternative solutions for replacement of organs and tissues.
The CRTI UMR1064 and the clinical departments of Clinical Immunology, Nephrology and Urology at CHU Nantes together form the Institute of Transplantation-Urology-Nephrology (ITUN). The kidney and pancreas transplantation program of the ITUN ranks among the best in France and Europe.
About TxCell – www.txcell.com
TxCell is a biotechnology company that develops platforms for innovative, personalized T cell immunotherapies for the treatment of severe chronic inflammatory and autoimmune diseases with high unmet medical need. TxCell is targeting a range of autoimmune diseases (both T-cell and B-cell-mediated) including Crohn’s disease, lupus nephritis, bullous pemphigoid and multiple sclerosis, as well as transplantation-related inflammatory disorders.
TxCell is the only clinical-stage cellular therapy company fully dedicated to the science of regulatory T lymphocytes (Tregs). Tregs are a recently discovered T cell population for which anti-inflammatory properties have been demonstrated. Contrary to conventional approaches based on non-specific polyclonal Tregs, TxCell is exclusively developing antigen-specific Tregs. This antigen specificity may either come from pre-existing Treg cell T-Cell Receptor (TCR) or from genetic modifications with Chimeric Antigen Receptor (CAR). TxCell is developing two proprietary technology platforms, ASTrIA, which is composed of non-modified naturally antigen-specific Tregs, and ENTrIA, which is composed of genetically-engineered Tregs.
Based in Sophia-Antipolis, France, TxCell is listed on Euronext Paris and currently has 45 employees.
