The present invention relates to: anti-PSMA antibodies or
antigen-binding fragments thereof; nucleic acids encoding same;
recombinant expression vectors comprising the nucleic acids; host cells transfected with the
recombinant expression vectors; methods for preparing the antibodies or
antigen-binding fragments thereof; chimeric receptors (CARs) comprising the antibodies or
antigen-binding fragments thereof; immune
cell therapeutic agents comprising the chimeric receptors;
antibody-
drug conjugates (ADC) having the
antibody or antigen-binding fragment thereof conjugated to a
drug; compositions comprising the antibodies or antigen-binding fragments thereof, for diagnosing, preventing, or treating
cancer; methods for diagnosing, preventing, or treating
cancer; and uses thereof. The anti-PSMA antibodies or antigen-binding fragments thereof, according to the present invention, exhibit superior binding affinity compared to conventional anti-PSMA antibodies, and can be usefully employed in diagnosing, preventing, or treating target tumors or cancers.
