The Neomed Institute, which will start by advancing three pain molecules contributed by AstraZeneca, will work to advance early-stage candidates through proof-of-concept and then license out the programs.

The idea of extending the human lifespan has long fascinated the public and challenged scientists. Funding for research into ageing processes, and the R&D of therapeutics to slow them, is increasing. Recent findings suggest that progress has been made, motivated in part by the rapid growth of elderly populations that might benefit from such advances. Furthermore, economists predict that many countries may face bankruptcy by 2050 (or earlier) because of rising healthcare expenditures associated with care of the elderly.

A group of drug discovery companies believes it has found a way to use scientific discoveries about the genetics of aging to develop novel drugs for specific diseases. These companies begin with insights from animal models of longevity and long-lived human populations, which they hope will help them discover new targets for age-related diseases. Several companies have rallied around calorie restriction, an intervention known to increase lifespan in laboratory animals, and are characterizing genetic and phenotypic changes associated with calorie restriction. Others believe they have found key genes that regulate aging, and hope to use this knowledge to develop drugs for such age-related as diseases as cardiovascular disease, stroke, cancer, and diabetes. The challenges for companies will be to validate mechanisms implicated in aging, and then link them to specific diseases. However, the diseases of aging are some of the toughest drug development categories; they're often progressive diseases that develop over the course of years, and proving that drugs slow down disease progression or prevent onset involves tough endpoints.
