Gemcitabine elaidate is an ester of anticancer drug gemcitabine and elaidic fatty acid. The motivation to make an ester was to facilitate gemcitabine uptake and prolong retention in the cell. The drug is converted to parent compound gemcitabine both inside and outside the cell. Gemcitabine elaidate was developed by Clavis Pharma for treatment of solid tumors, including non-small cell lung cancer and pancreatic cancer, but its development was discontinued after product missed the primary endpoint in the Phase II LEAP trial to treat metastatic pancreatic cancer.

Sample Use Guides

In Vivo Use Guide

In phase 2 study against pancreatic cancer, the drug was administered intravenously at 1250 mg/m2/d on day 1, 8 and 15 of each 4-week cycle.

Route of Administration: Intravenous

In Vitro Use Guide

The in vitro experiments were performed in cell lines of leukemia and solid tumor origin, both sensitive and resistant to gemcitabine. All populations were cultured at 37°C in a humidified atmosphere of 95% air and 5% CO2. Sensitivity to drugs was defined by the concentration of the drug causing a growth inhibition of 50% (IC50) after 72 h drug exposure of the cells. The cells were plated in 24-well plates in different densities, depending on their doubling times, to enable log-linear growth for 72 h. Drugs were added directly after plating the cells. Final concentrations of the drugs in the wells ranged from 2.10−10 to 10−3 M.
