Phase I, II, III, and IV Drug Trials:
- Phase I (One) Drug Trials. Phase 1 drug trials include the initial introduction of an investigational new drug into humans. These studies are typically closely monitored and are conducted with a small group of healthy volunteers (20-80); sometimes, where the drug is intended for use in patients with a particular disease, however, such patients may participate as subjects.
- Phase II (Two) Drug Trials. Phase 2 trials include controlled clinical studies conducted to evaluate the drug’s effectiveness for a particular indication in patients with the disease or condition under study, and to determine the common short-term side effects and risks associated with the drug. These studies are typically well controlled, closely monitored, and conducted with a larger number of subjects (100-300).
- Phase III (Three) Drug Trials. Phase 3 drug trials involve the administration of a new drug to a larger number of patients in different clinical settings to determine its safety, effectiveness, and appropriate dosage. They are performed after preliminary evidence of effectiveness has been obtained, and are intended to gather necessary additional information about effectiveness and safety for evaluating the overall benefit-risk relationship of the drug, and to provide an adequate basis for physician labeling. These studies are conducted with large groups of subjects (1,000-3,000).
- Phase IV (Four) Drug Trials. Concurrent with marketing approval, the FDA may seek agreement from the sponsor to conduct certain post-marketing (Phase 4) studies to delineate additional information about the drug’s risks, benefits, and optimal use. These studies could include, but would not be limited to, studying different doses or schedules of administration than were used in Phase 2 studies, use of the drug in other patient populations or other stages of the disease, or use of the drug over a longer period of time.
