In drug development, preclinical development (also termed preclinical studies or nonclinical studies) is a stage of research that begins before clinical trials (testing in humans) and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals.
Dose-ranging is usually a pre-clinical, phase I or early phase II clinical trial. Typically a dose ranging study will include a placebo group of subjects, and a few groups that receive different doses of the test drug. For instance, a typical dose-ranging study may include four groups: a placebo group, low-dose group, medium-dose group and a ...
The design of a clinical trial will depend on the drug and the phase of its development. Some clinical trials are conducted after a device or drug is approved to follow for safety. Control group is a group (or cohort) of individual patients that is used as a standard of comparison within a clinical trial. The control group may be taking a ...
