Each class of product may undergo different types of preclinical research. For instance, drugs may undergo pharmacodynamics, pharmacokinetics, ADME, and toxicology testing. This data allows researchers to allometrically estimate a safe starting dose of the drug for clinical trials in humans. Medical devices that do not have drug attached will not undergo these additional tests and may go directly to good laboratory practices testing for safety of the device and its components. Some medical devices will also undergo biocompatibility testing which helps to show whether a component of the device or all components are sustainable in a living model. Most preclinical studies must adhere to GLPs in ICH Guidelines to be acceptable for submission to regulatory agencies such as the Food and Drug Administration in the United States.
In drug development, preclinical development, also termed preclinical studies or nonclinical studies, is a stage of research that begins before clinical trials and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals. The ultimate goals of preclinical studies are to accurately model, in animals, the desired biological effect of a drug in order to predict treatment outcome in patients, and to identify and characterize all toxicities associated with a drug in order to predict adverse events in people for informed.
While preclinical research answers basic questions about a drug’s safety, it is not a substitute for studies of ways the drug will interact with the human body. “Clinical research” refers to studies, or trials, that are done in people. Preclinical research may take anywhere from one to six years. Researchers only take the most promising potential treatments through the journey to market.
New treatments then go through several clinical trial phases. These phases test the treatments for safety and effectiveness. Clinical Development, also called Drug Development, is a blanket term used to define the entire process of bringing a new drug or device to the market. It includes drug discovery/product development, pre-clinical research and clinical trials.
Discovery involves a number of processes like target identification and validation, hit identification, lead generation and optimization and finally the identification of a candidate for further development. Development, on the other hand, includes optimization of chemical synthesis and its formulation, toxicological. Modern drug discovery involves the identification of screening hits, medicinal chemistry and optimization of those hits to increase the affinity, selectivity, efficacy/potency, metabolic stability, and oral bioavailability. Pharmaceutical scientists are individuals who perform a variety of tasks related to the research, discovery, development, and testing of drugs and other pharmaceutical treatments.
Normally, a small group of 20-100 healthy volunteers will be recruited. These trials are often conducted in a clinical trial clinic, where the subject can be observed by full-time staff. These clinical trial clinics are often run by contract research organization who conducts these studies on behalf of pharmaceutical companies or other research investigators. The subject who receives the drug is usually observed until several half-lives of the drug have passed. This phase is designed to assess the safety (pharmacovigilance), tolerability, pharmacokinetics, and pharmacodynamics of a drug. Phase-I trials normally include dose-ranging, also called dose escalation studies, so that the best and safest dose can be found and to discover the point at which a compound is too poisonous to administer.
