This Code system is used in the following value sets:

  • ValueSet: Research Study Phase (Codes for the stage in the progression of a therapy from initial experimental use in humans in clinical trials to post-market evaluation.)

Codes for the stage in the progression of a therapy from initial experimental use in humans in clinical trials to post-market evaluation.

This case-sensitive code system http://hl7.org/fhir/research-study-phase defines the following codes:

n-a N/ATrials without phases (for example, studies of devices or behavioral interventions).btn btn
early-phase-1 Early Phase 1Designation for optional exploratory trials conducted in accordance with the United States Food and Drug Administration's (FDA) 2006 Guidance on Exploratory Investigational New Drug (IND) Studies. Formerly called Phase 0.btn btn
phase-1 Phase 1Includes initial studies to determine the metabolism and pharmacologic actions of drugs in humans, the side effects associated with increasing doses, and to gain early evidence of effectiveness; may include healthy participants and/or patients.btn btn
phase-1-phase-2 Phase 1/Phase 2Trials that are a combination of phases 1 and 2.btn btn
phase-2 Phase 2Includes controlled clinical studies conducted to evaluate the effectiveness of the drug for a particular indication or indications in participants with the disease or condition under study and to determine the common short-term side effects and risks.btn btn
phase-2-phase-3 Phase 2/Phase 3Trials that are a combination of phases 2 and 3.btn btn
phase-3 Phase 3Includes trials conducted after preliminary evidence suggesting effectiveness of the drug has been obtained, and are intended to gather additional information to evaluate the overall benefit-risk relationship of the drug.btn btn
phase-4 Phase 4Studies of FDA-approved drugs to delineate additional information including the drug's risks, benefits, and optimal use.btn btn
