EPHA2 BITE MOLECULES AND USES THEREOF.

摘要

The present invention relates to bispecific single chain antibodies comprising a first binding domain that irnmunospecifÿcally binds to the T-cell antigen CD3 and a second binding domain that immunospecifically binds to the EphA2 receptor. Such bispecific single chain antibodies are encompassed by the term "EphA2-BiTEs." The present invention further relates to methods and compositions designed for the treatment, prevention and/or management of disorders associated with aberrant expression and/or activity of EphA2. Such disorders include, but are not limited to, cancer, non-cancer hyperproliferative cell disorders, and infections. The invention further relates to vectors comprising polynucleotides encoding the EphA2 -BiTEs of the invention, host cells transformed therewith, and their use in the production of said EphA2-BiTEs. The invention also provides compositions, including pharmaceutical compositions, comprising any of the aforementioned EphA2-BiTEs, polynucleotides or vectors either alone or in combination with one or more prophylactic or therapeutic agents. Also disclosed are methods of screening for said EphA2 -BiTEs and kits comprising any of the aforementioned compositions and diagnostic reagents.
