Phase II clinical programs historically have experienced the lowest success rate of the four development phases. In 2010, the percentage of Phase II trials that proceeded to Phase III was 18%, [16] and only 31% of developmental candidates advanced from Phase II to Phase III in a study of trials over 2006–2015. [17]
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.
Schematic block diagram of an adaptive design for a clinical trial [1] In an adaptive design of a clinical trial, the parameters and conduct of the trial for a candidate drug or vaccine may be changed based on an interim analysis. [2] [1] [3] Adaptive design typically involves advanced statistics to interpret a clinical trial endpoint. [1]
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. [47] Phase III
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 ...
In a 2021 placebo controlled phase II clinical trial, KarXT met the primary endpoint. [12] In March 2023, Karuna Therapeutics announced that KarXT had met its primary endpoint in a phase III trial, EMERGENT-3, and that it was submitting the drug for approval by the US Food and Drug Administration (FDA).
