preclinical phase
Noun: * A stage of medical research: The "preclinical phase" refers to the stage in the development of a new drug, vaccine, or medical device where it is tested in laboratory settings and on animal subjects. The primary goal is to gather initial data on safety, biological activity, and dosage before the intervention can be tested in human clinical trials.
This term is used specifically in the context of medical and pharmaceutical research to describe the essential investigative work that precedes human testing. * The new compound showed promising results during the preclinical phase, allowing the company to apply for approval to begin human trials. * Extensive preclinical phase testing is required by regulatory agencies to ensure basic safety before any exposure to human volunteers.
- "to enter/complete the preclinical phase": This describes the transition of a research candidate into or out of this stage of testing.
- The vaccine candidate has successfully completed the preclinical phase and will now move into Phase I trials.
- The term is often contrasted with "clinical phase" or "clinical trial," which denote the subsequent stages of testing in human participants.
- Preclinical (adjective): Of or relating to this phase.
- Preclinical data suggests the drug is effective against the virus.
- Preclinical study (noun phrase): A specific investigation conducted during this phase.
- The results of the preclinical study were published in a scientific journal.
- Clinical trial (noun phrase): The subsequent phase of research involving human subjects.
- Preclinical testing
- Non-clinical research
- Animal testing stage (less formal, more specific)
- In vitro testing: Laboratory testing conducted in controlled environments outside a living organism (e.g., in a petri dish), often part of the preclinical phase.
- In vivo testing: Testing conducted within a living organism (e.g., animal models), a core component of the preclinical phase.
- Investigational New Drug (IND) application: The formal request to regulatory authorities (like the FDA) to begin human clinical trials, which is submitted after the preclinical phase.
- a laboratory test of a new drug or a new invasive medical device on animal subjects; conducted to gather evidence justifying a clinical trial
