AstraZeneca to acquire TeneoTwo and its clinical-stage T-cell engager, strengthening haematological cancer pipeline

AstraZeneca announced an agreement to acquire TeneoTwo, Inc. (TeneoTwo), including its Phase I clinical-stage CD19/CD3 T-cell engager, TNB-486, currently under evaluation in relapsed and refractory B-cell non-Hodgkin lymphoma.

The acquisition of TNB-486 aims to accelerate the development of this potential new medicine for B-cell haematologic malignancies, including diffuse large B-cell lymphoma and follicular lymphoma. Building on the success of Calquence (acalabrutinib), TNB-486 further diversifies AstraZeneca’s haematology pipeline that spans multiple therapeutic modalities and mechanisms to address a broad spectrum of blood cancers.

TNB-486 belongs to a class of therapeutic antibodies known as T-cell engagers, which are emerging as a promising therapeutic approach in haematologic malignancies and solid tumours. T-cell engagers are bispecific molecules that are engineered to redirect the immune system’s T-cells to recognise and kill cancer cells. By binding to both CD19, an antigen expressed on B-cells, and to the CD3 receptor on T-cells, TNB-486 activates and recruits T-cells to CD19-expressing tumours where they can elicit an immune response.

Anas Younes, Senior Vice President Haematology R&D, AstraZeneca said: “By redirecting the body’s natural immune response to target B-cell malignancies, TNB-486 alone or in combination with CD20-targeted therapy could potentially deepen clinical responses and improve patient outcomes. We believe this innovative molecule, which was designed to optimise the therapeutic window of T-cell activation, will enable us to explore novel combinations that have the potential to become new standards of care in this setting.”
