Clinical Trials Glossary

Active Controlled: Subjects are randomly assigned to either a recognized effective treatment or the study drug.

Dose Escalation: The amount of the drug is either periodically increased or increased with each new trial group that is added, so that researchers can determine how the drug is tolerated in patients.

Double Blind: Neither the researchers nor the patients know which patients are receiving the experimental drug and which are receiving a placebo or a different drug.

Multi-center: The trial is being conducted at several geographically separate sites.

Open Label: Both the researcher and the patient know the full details of the treatment being administered.

Phase 1: Initial studies to determine metabolism and pharmacologic action of the drug, side effects with increasing doses, and early evidence of effectiveness.

Phase 2: Controlled studies to evaluate the drug’s effectiveness for particular indications in patients with the condition under study, and to determine the common short-term side effects and risks.

Phase 3: Expanded controlled and uncontrolled trials to evaluate the overall benefit-risk relationship of the drug and to provide a basis for physician labeling.

Placebo Controlled: An inactive substance (placebo) is given to one group of participants, while the drug being tested is given to another group.

Randomized: Participants are randomly assigned to one of two or more treatment groups within the trial.
