The invention relates to COnditional Bispecific Redirected Activation constructs, or COBRAs, that are administered in an active pro-drug format. Upon exposure to tumor proteases, the constructs are cleaved and activated, such that they can bind both tumor target antigens (TTAs) as well as CD3, thus recruiting T cells expressing CD3 to the tumor, resulting in treatment.

Constrained conditionally activated binding proteins

Provided herein are trispecific antigen-binding proteins comprising a domain binding to CD3, a half-life extension domain, and a domain binding to a target antigen. Also provided are pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such trispecific antigen-binding proteins. Also disclosed are methods of using the disclosed trispecific antigen-binding proteins in the prevention, and/or treatment diseases, conditions and disorders.

Trispecific binding proteins and methods of use

Disclosed herein are single chain variable fragment CD3 binding proteins with improved binding affinities, and robust aggregation profiles. Also described are multispecific binding proteins comprising a single chain variable fragment CD3 binding protein according to the instant disclosure. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are provided.

Single chain variable fragment CD3 binding proteins

Disclosed herein are single domain serum albumins binding proteins with improved thermal stability, binding affinities, and robust aggregation profiles. Also described are multispecific binding proteins comprising a single domain serum albumin binding protein according to the instant disclosure. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are provided.

Single domain serum albumin binding protein

Disclosed herein are PSMA binding proteins with improved binding affinities, and robust aggregation profiles. Also described are multispecific binding proteins comprising a PSMA binding protein according to the instant disclosure. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are further provided.

Prostate specific membrane antigen binding protein

Provided herein are prostate specific membrane antigen (PSMA) targeting trispecific proteins comprising a domain binding to CD3, a half-life extension domain, and a domain binding to PSMA. Also provided are pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such PSMA targeting trispecific proteins. Also disclosed are methods of using the disclosed PSMA targeting trispecific proteins in the prevention, and/or treatment diseases, conditions and disorders.

PSMA targeting trispecific proteins and methods of use

Described herein are binding proteins that specifically bind to human CD33, and in particular to bispecific binding proteins that specifically bind to human CD33 and human CD3. Also described herein are bispecific tandem diabodies that bind to CD33 and CD33, and their uses for immunotherapy of CD33+ cancers, diseases and conditions such as acute myeloid leukemia (AML).

Methods of using bispecific CD33 and CD3 binding proteins

Described herein are binding proteins that specifically bind to human CD33, and in particular to bispecific binding proteins that specifically bind to human CD33 and human CD3. Also described herein are bispecific tandem diabodies that bind to CD33 and CD33, and their uses for immunotherapy of CD33cancers, diseases and conditions such as acute myeloid leukemia (AML).
