According to a story from biotechconnectionbay.org, medical researchers are beginning to more closely investigate that possibilities that drug repurposing, or using old drugs for treating different illnesses, could offer. While it is true that the development of new drugs is moving apace, it is often a long and costly process. On average, the development of a new therapy costs around a billion dollars and can take nearly a decade to complete.
Drug repurposing offers a potentially cheaper and quicker alternative, and has the potential to make significant impact in treating rare disease. After all, developing rare disease drugs is often a more timely and costly process than making treatments for the most common illnesses. Many drug developers don’t bother because of the limited pool of patients that would benefit and therefore spend money on the drug; even with federal incentives like orphan drug designation, it simply isn’t worth it to many pharma companies.
The problems of time and cost are also getting progressively worse, indicating a significant loss in research and development efficiency in the pharmaceutical industry. Of all drug candidates submitted for trials and FDA approval, only about ten percent ever make it to the market. However, about 63 percent of drugs to clear the first Phase I trial hurdle. This could be a potential resource of drugs that could be repurposed, and if they have made it through Phase I, then they have at least been established as safe to use.
