Combining gemcitabine with MRK003, an experimental drug, triggers a chain of events leading to pancreatic cancer cell death, researchers from Cambridge reported in the Journal of Experimental Medicine. The researchers explained that when the two drugs are combined, the effect of each one is multiplied, thus intensifying the destruction of pancreatic cancer cells.
Professor David Tuveson, from the Cambridge Research Institute, UK, and team demonstrated in animal studies that MRK003, an experimental medication, when combined with chemotherapy medication gemcitabine, set off a domino effect which ultimately destroyed the malignant cells.
The drug combo is being used in a human study, a clinical trial, which is being managed by Cambridge University Hospitals Foundation Trust, together with Cancer Research UK's Drug Development Office.
MRK003 is a gamma secretase inhibitor. It inhibits, or blocks a crucial cell signaling pathway in both pancreatic cancer cells and the cells in the lining of blood vessels that supply the tumor with vital nourishment (endothelial cells).
The researchers found that when MRK003 is added to gemcitabine, the chemotherapy drug's ability to destroy tumors was significantly enhanced. Gemcitabine is a nucleoside analog, which is marketed as Gemzar by Eli Lilly. Gemcitabine is commonly used in pancreatic cancer therapy, as well as non-small cell lung cancer, bladder cancer and breast cancer.
