Clinical Trial Reaches Key Milestone

 

 

SAN ANTONIOMay 13, 2015 /PRNewswire/ -- GenSpera, Inc. (OTCQB: GNSZ) announced today the successful completion of the first stage of an ongoing Phase II study of its lead investigational agent, mipsagargin (G-202), in glioblastoma (brain cancer) and the continuation of enrollment for an expansion phase of the trial. The two-stage, single-arm, open-label study (NCT02067156) is led by David Piccioni, M.D., Ph.D. and Santosh Kesari, M.D., Ph.D. at the UC San Diego Moores Cancer Center in La Jolla, Calif., and will evaluate the efficacy, safety and central nervous system (CNS) exposure in patients with recurrent or progressive glioblastoma. 

Glioblastomas, the most common form of brain tumors in adults, are particularly resistant to conventional chemotherapy drugs as most cannot cross the blood-brain barrier. This disadvantage of conventional chemotherapy does not apply to mipsagargin because mipsagargin directly attacks the prostate-specific membrane antigen (PSMA)-expressing cells of the tumor-associated blood vessels that comprise the blood-brain barrier.

"Initial indications that mipsagargin is well-tolerated and has some activity in glioblastoma are encouraging," said David Piccioni, M.D., Ph.D. at UC San Diego. "We look forward to expanding on this research and potentially bringing about an important new therapy for people with this aggressive disease."

"Glioblastoma patients have few treatment options and we are committed to using our innovative platform technology to develop treatments that can help them," said Craig Dionne, Ph.D., chief executive officer at GenSpera. "We designed this study to provide an initial assessment of the safety and efficacy of mipsagargin in targeting glioblastoma tumors and we are pleased by the initial results."

Mipsagargin is a prodrug in human clinical trials for several different tumor types. Mipsagargin consists of a thapsigargin derivative, 12ADT, coupled to a peptide that helps solubilize the prodrug and prevents its internalization into cells until the peptide is removed. The mechanism of action works by targeting the enzyme PSMA, which is highly expressed on the surface of almost all cancer tumor vasculature, including those of glioblastoma. PSMA recognizes and removes the peptide, releasing the active ingredient 12ADT into the cell and bringing about cell death. The prodrug delivery system ensures that mipsagargin is activated only within the tumor, providing greater anti-tumor efficacy and minimizing side effects.
