About GenSpera

GenSpera’s technology platform combines a powerful, plant-derived cytotoxin (thapsigargin) with a prodrug delivery system that targets release of the drug within the tumor. Unlike typical chemotherapeutic agents, thapsigargin kills cells irrespective of the rate of cell division, which may provide an effective approach to kill both fast- and slow-growing cancers as well as cancer stem cells. GenSpera’s lead drug candidate, G-202, is activated by the enzyme PSMA, which is found at high levels in prostate cancer and in the vasculature of almost all solid tumors, and is therefore expected to have efficacy in a wide variety of tumor types.

Data from the G-202 Phase Ib program in solid tumor patients demonstrated that G-202 is well-tolerated with prolonged disease stabilization observed in several hepatocellular carcinoma patients whose disease had previously worsened on standard therapy. A Phase II clinical trial in patients with hepatocellular carcinoma is underway. For more information, please visit the company’s website: www.genspera.com.
