    Technology description follows.

Albumin Binding Prostate Cancer Treating Compositions

    The invention pertains to a therapeutic agent that includes a 
chemically conjugated residue derived from (((R-)-1-carboxy-2-
mercaptoethyl)carbamoyl)-L-glutamic acid that is further bound to an 
Evans blue analog (EB). The EB analog reversibly binds to circulating 
serum albumin to provide a radiopharmaceutical that retains affinity 
and specificity to prostate specific membrane antigen (PSMA; in this 
case PSMA-617). PSMA is a surface molecule shown to be specifically 
expressed by prostate tumor cells. PSMA expression levels correlate 
with disease stage and with hormone refractory cancers. Although most 
PSMA expression appears to be restricted to the prostate cancer, low 
levels of expression can also be detected in the brain, kidneys, 
salivary glands, and small intestine. The antigen is also shown to be 
expressed by neovascular tumor vessels of multiple other cancers. 
Inclusion of the Evans blue analog promotes high internalization and 
retention rates of the conjugated target ligand, and therefore, higher 
accumulation in PSMA positive tumors. Labeling EB-PSMA-617 derivatives 
with the therapeutic beta emitters, e.g., 90Y, 86Y, and 177Lu gives 
rise to improved tumor response and survival rates.
    Potential Commercial Applications:

 Cancer therapeutics
 Higher stability/Lower toxicity

    Development Stage:
