GenSpera Enters National Phase with Patent Application for Injectable Prodrug Formulations

SAN ANTONIO, May 6, 2015 /PRNewswire/ -- GenSpera, Inc. GNSZ announced today that the patent application "Injectable Cancer Compositions" has entered the national phase application process in 17 countries and regions, including Europe, Eurasia, Japan, China, Brazil and the United States. When awarded, the resulting patent application will extend the exclusivity period for GenSpera's core intellectual property around its entire platform technology, including its lead drug candidate, mipsagargin, until 2033.

This recent patent application contains composition-of-matter claims for an injectable form of thapsigargin-containing prodrugs, including a lyophilized emulsion form of the drugs, which has demonstrated physical and chemical stability under appropriate storage conditions. The injectable form of these prodrugs is not only easier to administer to patients as compared to a standard infusion, but it is also easier to store and transport to a patient site.

"These types of patents are extremely important in building true intrinsic value in GenSpera's core assets," said Craig A. Dionne, Ph.D., GenSpera's chief executive officer. "Not only do they extend patent life in all major markets, they also expand opportunities for use by non-oncologists, such as urologists and other primary caregivers, who may not have easy access to infusion bays to deliver drugs. This aspect of drug life-cycle management has been particularly appreciated during our discussions with potential licensing partners."
