An unintended reaction to a drug taken
at doses normally used in man for prophylaxis, diagnosis,

function. In clinical trials, an ADR would include any injuries
by overdosing, abuse/dependence, and unintended interactions
with other medicinal products.
Adverse Event (AE)
A negative experience encountered by
an individual during the course of a clinical trial, that
is associated with the drug. An AE can include previously
undetected symptoms, or the exacerbation of a pre-existing

Blinding
The process through which one or more
parties to a clinical trial are unaware of the treatment
assignments. In a single-blinded study, usually the subjects
are unaware of the treatment assignments. In a double-blinded
study, both the subjects and the investigators are unaware
of the treatment assignments. Also, in a double-blinded
study, the monitors and sometimes the data analysts are
unaware. "Blinded" studies are conducted to prevent
the unintentional biases that can affect subject data when
treatment assignments are known.

conducted with Phase I & II studies.
Orphan Drug
A designation of the FDA to indicate
a therapy developed to treat a rare disease (one which afflicts
a U.S. population of less than 200,000 people). Because
there are few financial incentives for drug companies to

companies (i.e. tax advantages and extended marketing exclusivity)
that develop these drugs.
Over-the-Counter (OTC)

a physician's prescription.
Patient

studies compare various treatment options in terms of their
cost, both financial and quality-of-life. Also referred
to as "outcomes research".
Phase I Study
The first of four phases of clinical
trials, Phase I studies are designed to establish the effects
of a new drug in humans. These studies are usually conducted
on small populations of healthy humans to specifically determine
a drug's toxicity, absorption, distribution and metabolism.
Phase II Study

I trials, a drug is then tested for safety and efficacy
in a slightly larger population of individuals who are afflicted
with the disease or condition for which the drug was developed.
Phase III Study
The third and last pre-approval round
of testing of a drug is conducted on large populations of
afflicted patients. Phase III studies usually test the new
drug in comparison with the standard therapy currently being
used for the disease in question. The results of these trials
usually provide the information that is included in the
package insert and labeling.
Phase IV Study
After a drug has been approved by the
FDA, phase IV studies are conducted to compare the drug
to a competitor, explore additional patient populations,
or to further study any adverse events.
Pivotal Study
Usually a phase III study which presents
the data that the FDA uses to decide whether or not to approve
a drug. A pivotal study will generally be well-controlled,
randomized, of adequate size, and whenever possible, double-blind.
Placebo

the drug being tested. It is used as a control to rule out
any psychological effects testing may present. Most well-designed
studies include a control group which is unwittingly taking
a placebo.
Pre-Clinical Testing

pre-clinical studies must be conducted either in vitro
but usually in vivo on animals to determine that
the drug is safe.

through this program.
Unexpected Adverse
Drug Reaction
A reaction that is not consistent in
nature or severity with study application.
