phase II trial
The second step in testing an experimental drug
(or other treatment)
in humans. Typically, Phase II trials are done only if Phase I trials have shown that the drug is safe, but sometimes Phase I and Phase II trials are combined. Phase II trials are designed to evaluate the drug's effectiveness in people with the disease or condition being studied and to determine the common short-term adverse effects and risks associated with the drug. Phase II trials involve more participants
(often several hundred)
and typically last longer than Phase I trials.
phase III trial
The third step in testing an experimental drug
(or other treatment)
in humans. Phase III trials are conducted to confirm and expand on safety and effectiveness results from Phase I and II trials, to compare the drug to standard therapies for the disease or condition being studied, and to evaluate the overall risks and benefits of the drug. This trial phase recruits a large group of people with the disease or condition, usually ranging from 1,000 to 3,000 participants. Results from Phase III trials provide information that the Food and Drug Administration
(FDA)
needs to consider the drug for approval.
phase IV trial
Testing in humans that occurs after a drug
(or other treatment)
has already been approved by the Food and Drug Administration
(FDA)
and is being marketed for sale. Phase IV trials are conducted to determine long-term safety and effectiveness and to identify adverse effects that may not have been apparent in prior trials. Thousands of participants are usually recruited to volunteer for this phase of clinical testing.
