Dyslipidemias include elevated LDL (bad) cholesterol, low HDL (good) cholesterol and/or elevated triglycerides, all of which increase the risk of cardiovascular disease, the leading cause of death in the United States. Although widely used drugs such as statins lower LDL cholesterol effectively, they are less efficacious at improving other lipid profiles.
PPARs are a subfamily of intracellular receptors that regulate lipid and glucose homeostasis. They play a key role in fat tissue stores and metabolism, as well as enhancing cellular responses to insulin.
"We are very pleased that GSK has decided to continue development of 501516, which may represent an important advance in the treatment of dyslipidemias and associated cardiovascular disorders," said Andres Negro-Vilar, M.D., Ph.D., Ligand's executive vice president for research and development and chief scientific officer.
Under the recently amended terms of the research and development agreement between Ligand and GSK, GSK is responsible for the development and registration of 501516, and may pay Ligand milestone payments of up $12 million as the product moves through the development process. GSK has exclusive worldwide marketing rights to 501516, and will pay Ligand up to double-digit royalties on potential product sales. If GSK decides not to proceed with development of 501516, Ligand will retain the right to develop and commercialize the product.
