C54721 Early Phase 1 Exploratory clinical trials, in a small number of participants, that are conducted early in Phase 1. The investigational trial intervention is administered at a low dose for a limited time. Early Phase 1 trials provide insights into a variety of parameters such as pharmacokinetic, pharmacodynamic, and other biomarkers. They involve limited human exposure, have no therapeutic or diagnostic intent, and are not intended to assess clinical tolerability. y
C15600 Phase 1 Exploratory clinical trials that may be first-in-human, conducted in a small number of patients or healthy volunteers to evaluate clinical safety, tolerability, or therapeutic intent (pharmacokinetics and pharmacodynamics) of an investigational trial intervention. y
C15693 Phase 1/Phase 2 A single clinical trial that combines elements of Phase 1 and Phase 2 trials, which may begin as a Phase 1 trial and transition into Phase 2 based upon predetermined criteria. y
C198366 Phase 1/Phase 2/Phase 3 A single clinical trial that combines elements of Phase 1, Phase 2, and Phase 3 trials, which may begin as a Phase 1 trial and transitions through Phase 2 and Phase 3 based upon predetermined criteria. y
C198367 Phase 1/Phase 3 A single clinical trial that combines elements of Phase 1 and Phase 3 trials, which may begin as a Phase 1 trial and transition into Phase 3 based upon predetermined criteria. y
C15601 Phase 2 Exploratory trials conducted to evaluate the safety and efficacy of the investigational trial intervention in patients with the disease or condition. Objectives may include, but are not limited to, clinical pharmacology, dose-ranging (dose-response, frequency of dosing), type of patients, or other characteristics of safety and efficacy. y
C15694 Phase 2/Phase 3 A single clinical trial that combines elements of Phase 2 and Phase 3 trials, which may begin as a Phase 2 trial and transition into Phase 3 based upon predetermined criteria. y
C217024 Phase 2/Phase 3/Phase 4 A single clinical trial that combines elements of Phase 2, Phase 3, and Phase 4 trials, which may begin as a Phase 2 trial and transitions through Phase 3 and Phase 4 based upon predetermined criteria. y
C15602 Phase 3 Confirmatory trials conducted to demonstrate safety, efficacy and tolerability of the investigational trial intervention in patients with the disease or condition. Their objectives are to evaluate the overall benefit-risk relationship and may provide substantial evidence for regulatory approval and product information. y
C217025 Phase 3/Phase 4 A single clinical trial that combines elements of Phase 3 and Phase 4 trials, which may begin as a Phase 3 trial and transition into Phase 4 based upon predetermined criteria. y
C15603 Phase 4 Post-approval (or post-marketing) trials conducted to further evaluate the safety and efficacy of an investigational trial intervention in its approved indication and may be conducted to address a regulatory requirement. These studies may explore use of the investigational trial intervention in the real-world setting of clinical practice and may also inform health economics and health technology assessments. y
