Pancreatic cancer is the fourth most frequent cause for cancer related deaths with a 5-year survival rate of only 1-4% and a median survival period of 4-6 months. We found that standard chemotherapy treatment with gemcitabine is not capable of eliminating but rather increasing the percentage of cancer stem cells (CSCs), suggesting that this standard therapy preferentially targets more differentiated and rapidly proliferating neoplastic cells. Therefore, other treatment modalities need to be evaluated, which may in addition allow removal of CSCs with the promise to eventually cure patients with pancreatic cancer. The purpose of this collaborative effort between the Ludwig-Maximilian-University and Geron Corporation (Menlo Park, CA, U.S.A.) is to investigate whether inhibition of telomerase by GRN163L, a potent enzymatic inhibitor of telomerase, may be capable of suppressing the clonogenic potential of CSC in vitro and in vivo.
