Talaris Therapeutics Announces Upcoming Presentations on FCR001 at the Virtual 2021 American Transplant Congress

Talaris Therapeutics, Inc. (Nasdaq: TALS), a late-clinical stage cell therapy company developing therapies with the potential to transform the standard of care in solid organ transplantation, certain severe autoimmune diseases, and certain severe non-malignant blood, immune and metabolic disorders, announced upcoming presentations of data from the company’s Phase 2 study of FCR001 at the American Transplant Congress taking place virtually June 4-9, 2021.

The accepted oral presentation includes data on the company’s analysis of peripheral blood chimerism as a biomarker for transplantation tolerance. Phase 2 data indicate that one, three, six, and 12-month chimerism levels are highly correlated with each other and increasingly predictive over time of the ability to withdraw immunosuppression at one year, suggesting that whole blood and T-cell chimerism could be a valuable surrogate marker of the ability to discontinue immunosuppression at one year without rejection of the transplanted organ.

In addition, a poster will report on the long-term follow-up of the company’s Phase 2 trial in living donor kidney transplant recipients. Among the 37 subjects administered FCR001, 26 displayed durable chimerism allowing for full withdrawal of immunosuppression, and updated data show that all stable chimeric subjects remain rejection-free with a minimum follow-up of four years and the longest follow-up of almost 12 years.

The company will also be delivering two invited presentations and two sponsored virtual lounge sessions.
