Information
Clinical trials involve controlled scientific
experiments on human subjects to test experimental drugs which have
completed intensive developmental and laboratory testing.
Trials are generally sponsored and paid for by pharmaceutical
companies, and must be conducted according to a strict standard and
guidelines set out by the Food and Drug Administration (FDA) in the
There are several “Phases” of clinical trials, beginning with Phase I trials on a small number of healthy patients to determine safety, and progressing through Phase II, III, IIIB and IV trials involving increasingly larger numbers of patients with the disease in question to evaluate effectiveness, side effects, dosage, etc. Only after completion of extensive clinical testing and thorough reviews by the FDA is a new drug approved for use.
The drug approval process is lengthy and
costly. It can take 15
years and cost $1 billion in research and development to bring a new
drug to market. Despite
the costs, the number of new drugs in development continues to grow
as advances in biopharmaceutical technology, genome mapping, stem
cells and nanotechnology provide researchers new and more focused
approaches to fighting disease.
As a result, the demand for clinical trials, which already
amounts to $30 billion globally, is growing rapidly.
Clinical trials are also becoming more complex and focused,
and recruiting suitable patients is a major challenge in traditional
markets such as the
