SAN ANTONIO, July 30, 2014 /PRNewswire/ -- GenSpera, Inc.

The patent US 8,772,226 B2 was issued July 8, 2014.
The patent contains composition claims for thapsigargin-containing prodrugs that can be radiolabelled and then activated by the enzymes Prostate Specific Membrane Antigen (PSMA), Prostate Specific Antigen (PSA) or Human Glandular Kallikrein 2 (hK2). The patent also claims methods of using such radiolabelled prodrugs for the detection, imaging and treatment of cancers in humans.
The co-inventors on the patent include Drs. Samuel Denmeade, John Isaacs and Soren Brogger Christensen who are all members of GenSpera's Scientific Advisory Board.
"As we evaluate G-202 further in the liver cancer and glioblastoma Phase II clinical trials it is clear that the technology described in this patent, when fully developed, would greatly aid in the selection of patients most likely to benefit from G-202 treatment," said Craig Dionne, PhD, GenSpera's CEO. "The issuance of this patent also exemplifies the breadth and diversity of GenSpera's intellectual property portfolio."
