preclinical test
Noun: A scientific experiment conducted in a controlled laboratory setting using animal subjects to evaluate the safety, biological activity, and efficacy of a new pharmaceutical drug or a new invasive medical device. The primary purpose is to collect sufficient data to determine if the product is safe and promising enough to justify proceeding to trials with human participants (clinical trials).
This term is used specifically in the context of medical and pharmaceutical research and development. It describes a critical, mandatory phase of testing that occurs before any human testing can begin.
- The new compound showed promising results in preclinical tests on mice.
- Before the vaccine candidate can be tested in humans, it must pass a series of rigorous preclinical tests.
- The research team is analyzing the data from the preclinical test of the new surgical device.
- Preclinical testing (often used as an uncountable noun phrase to refer to the overall phase or process): "The drug is still in preclinical testing."
- The term implies a systematic evaluation, often involving multiple studies assessing toxicity (how poisonous it is), pharmacokinetics (how the body absorbs, distributes, and excretes it), and pharmacodynamics (its biological effects).
- Preclinical trial: A synonym, though "test" is more general and "trial" can imply a more structured series of tests.
- Preclinical study: A very common synonym, emphasizing the research aspect.
- Animal trial/study/test: A broader term that describes the method (testing on animals) but not necessarily the purpose (justifying human trials).
- In vitro test: A related type of non-human test conducted in laboratory equipment (e.g., in a petri dish), often performed before or alongside (in a living animal) preclinical tests.
- Animal study
- Preclinical study
- Non-clinical test
- Laboratory animal test
The term is highly specific to regulatory science. A "preclinical test" is not simply any test done before a clinic opens; it is explicitly a benchmark in the drug/device development pipeline, defined by its goal of providing evidence for regulatory approval to commence clinical trials.
- a laboratory test of a new drug or a new invasive medical device on animal subjects; conducted to gather evidence justifying a clinical trial
