CLINICAL
TRIALS
Before
a drug can be offered to the public it must go through
several phases of rigorous testing to make sure it is
safe, efficient and does what it says it can do. The
testing is mandated and overseen by the U.S. Food and
Drug Administration (FDA) which is part of the U.S.
Department of Health and Human Services.
Under
the “Useful Resources” link on the Samaritan
Web site there are detailed descriptions of the drug
testing process set up by the FDA.
Briefly,
however, each drug starts out as an idea which grows
into a laboratory test. If successful, the laboratory
test becomes a series of preclinical tests, and could
eventually involve testing with animals. If the drug
continues to show promise, an investigational new drug
(IND) application is sought from the FDA. With approval
of the IND, the first of three phases of clinical trials
may begin, this time using real people. Assuming all
the clinical trials are successful, a new drug application
(NDA) is applied for from the FDA and a new drug is
on the market.
All
of the above may sound simple, but it isn’t. The
approval of a drug may take more than 15 years and cost
over $1 billion. And, according to the FDA, of every
5,000 drugs submitted for initial approval, only five
are selected to proceed to clinical trials, and only
one of the five can expect to be granted an NDA status.
