Clinical trials testing potential medical products are commonly classified into four phases. The drug development process will normally proceed through all four phases over many years. [1] When expressed specifically, a clinical trial phase is capitalized both in name and Roman numeral, such as "Phase I" clinical trial. [1]
A pivotal trial is typically a Phase III clinical trial in the multi-year process of clinical research intended to demonstrate and confirm the safety and efficacy of a treatment – such as a drug candidate, medical device or clinical diagnostic procedure – and to estimate the incidence of common adverse effects. [1]
Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery.It includes preclinical research on microorganisms and animals, filing for regulatory status, such as via the United States Food and Drug Administration for an investigational new drug to initiate clinical trials on humans, and may ...
[1] [3] [8] Each phase of the drug approval process is treated as a separate clinical trial. [1] [3] If the drug successfully passes through Phases I, II, and III, it will be approved by the national regulatory authority for use in the general population. Phase IV is post-approval studies. [8] Phase I includes 20 to 100 healthy volunteers or ...
The United States Food and Drug Administration's Investigational New Drug (IND) program is the means by which a pharmaceutical company obtains permission to start human clinical trials and to ship an experimental drug across state lines (usually to clinical investigators) before a marketing application for the drug has been approved.
A drug that receives a fast track designation is eligible for some or all of the following: [3] More frequent meetings with FDA to discuss the drug's development plan and ensure collection of appropriate data needed to support drug approval; More frequent written correspondence from FDA about such things as the design of the proposed clinical ...
Phase II-a is specifically designed to assess dosing requirements (how much drug should be given), [15] [47] while a Phase II-b trial is designed to determine efficacy (100–300 people), [1] assessing how well the drug works at the prescribed dose(s) to establish a therapeutic dose range and monitor for possible side effects.
The trials are typically conducted in three phases: [5] Phase 1: The drug is tested in 20 to 100 healthy volunteers to determine its safety at low doses. About 70% of candidate drugs advance to Phase 2. Phase 2: The drug is tested for both efficacy and safety in up to several hundred people with the targeted disease.
