Autolus Therapeutics announces publication in Blood Cancer Journal

LONDON, March 11, 2024 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announced a publication in Blood Cancer Journal entitled ‘Dual T-cell constant β chain (TRBC)1 and TRBC2 staining for the identification of T-cell neoplasms by flow cytometry.’ 1

Diagnosing leukemic T-cell malignancies poses challenges due to their resemblance to reactive T-cells. In the paper published by Pedro Horna of Mayo Clinic in collaboration with Autolus, the authors introduce a unique approach for identifying T-cell neoplasms by flow cytometry1. This method adopts the recently described monoclonal antibodies targeting TRBC1 and TRBC22, 3, to assess for TRBC-restriction as a surrogate of clonality. The strategy mirrors the routine and broadly adopted analysis of kappa and lambda immunoglobulin chain restriction for the identification of B-cell malignancies.

This innovative and simple strategy to detect clonal expansion of T-cells by flow cytometry has the potential to facilitate the development of more comprehensive diagnostic panels that can be seamlessly integrated into existing screening protocols, obviating the need for separate T-cell clonality assessments. Autolus is working with world leading flow cytometry companies, including Beckman Coulter Life Sciences, BD (Becton, Dickinson and Company) and Thermo Fisher Scientific, in order to enable the development and distribution of diagnostic panels based on these unique TRBC1 and TRBC2 antibodies.

Advancements in diagnostic approaches for T-cell malignancies, coupled with the development of TRBC1 and TRBC2-directed CAR T cell therapeutics4, may contribute to the improvement of therapeutic strategies in this area of unmet clinical need.

Forward-Looking Statements 
This press release contains forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that are not historical facts, and in some cases can be identified by terms such as "may," "will," "could," "expects," "plans," "anticipates," and "believes."
