SAN ANTONIO, Texas--(BUSINESS WIRE)--

GenSpera, Inc. (OTCBB:GNSZ) announced that its lead drug, G-202, has been selected by the Statewide Clinical Trials Network of Texas (CTNeT) for evaluation in a Phase II clinical trial in patients with hepatocellular carcinoma (HCC). CTNeT's selection of G-202 is the result of a competitive, peer-review process to identify promising molecularly-targeted agents with likelihood of clinical benefit and rapidly move them into the Phase II setting. The clinical trial, entitled “A Phase II, Multicenter, Single-Arm Study of G-202 as Second-Line Therapy Following Sorafenib for Adult Patients with Progressive Advanced Hepatocellular Carcinoma” is the first clinical trial launched by CTNeT, an organization founded by a grant from the Cancer Prevention and Research Institute of Texas (CPRIT) and focused on moving targeted therapies and clinical research forward at an accelerated pace.

“CTNeT was established to facilitate and coordinate multi-center collaboration among academic and community cancer centers across the state of Texas to conduct tissue-based, biomarker-driven clinical trials focused on advancing targeted, more personalized care for cancer,” said Charles Geyer, M.D., President and CMO of CTNeT. “G-202 represents an innovative targeted approach to treating cancer and has a strong rationale for evaluation in HCC. We are pleased to have the opportunity to evaluate this unique compound in our network.”

“Hepatocellular carcinoma is an aggressive disease, with the second highest increase in incidence and the highest increase in death rates of any tumor type over the last decade,” said Devalingam Mahalingam M.D., Ph.D., of the Cancer Therapy and Research Center (CTRC) at the University of Texas Health Science Center in San Antonio. Dr. Mahalingam participated in the Phase I study of G-202 and will serve as Study Chair and Principal Investigator (PI) of this Phase II trial. Dr. Mahalingam stated, “with sorafenib as the first effective and only approved treatment for patients with advanced HCC, it is critical that additional treatments be identified for this patient population. HCC tumors require a rich blood supply, making them an excellent target for G-202, which is activated by the protein PSMA that is expressed in tumor blood vessels but not in normal tissue or normal blood vessels. The incidence of HCC in Texas has increased 69% over the last decade and working through the statewide network of clinical trial sites will provide patients with HCC across many institutions in Texas access to this clinical trial.”

“The advantages of working with CTNeT for this Phase II study are quite significant for any oncology company,” said Craig A. Dionne, Ph.D., GenSpera CEO. “Hepatocellular carcinoma is the third leading cause of cancer deaths worldwide and the incidence is expected to rise, reflecting, in part, the current Hepatitis C epidemic. Most HCC cases are diagnosed at an advanced stage, when surgical resection is not an effective treatment option and patient outcome is poor. The ability to access CTNeT's network of clinical trial sites to rapidly enroll patients for the Phase II study will significantly reduce both the time necessary to complete the trial and its associated costs. In addition, participation of CTNeT's highly-experienced and collaborative staff will facilitate the operational feasibility of the clinical study.”

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 is evaluating its lead drug candidate, G-202 in a Phase Ib dose refinement study that is now closed to new patient accrual. G-202 will also be evaluated in a Phase II trial in patients with chemotherapy-naïve, metastatic castrate-resistant prostate cancer at multiple clinical sites in the United States and United Kingdom beginning in the fourth quarter of 2012.
