Phase III trials for dermatology may cost as low as $11 million, whereas a pain or anesthesia Phase III trial may cost as much as $53 million. [30] An analysis of Phase III pivotal trials leading to 59 drug approvals by the US Food and Drug Administration over 2015–16 showed that the median cost was $19 million, but some trials involving ...
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.

Using a single standard arm for comparison for all candidates in the trial saves significant costs over individual Phase 3 trials. All data are shared across the industry. [ 32 ] As of January 2016 [update] I-SPY 2 is comparing 11 new treatments against 'standard therapy', and is estimated to complete in Sept 2017. [ 33 ]
A study of clinical trials conducted in the United States from 2004 to 2012 found the average cost of Phase I trials to be between $1.4 million and $6.6 million, depending on the type of disease. Phase II trials ranged from $7 million to $20 million, and Phase III trials from $11 million to $53 million. [105]
The main goal of a dose-ranging study is to estimate the response vs. dose given, so as to analyze the efficacy and safety of the drug. Although such a response will nevertheless be available from phase III or phase IV trials, it is important to carry out dose-ranging studies in the earlier phase I or phase II stages. There are advantages to ...
The intent of a challenge study is to fast-track the timeline for providing evidence of safety and efficacy of a therapeutic drug or vaccine, especially by compressing (to a few months) the usually lengthy duration of Phase II–III trials (typically, many years). [2] [3] [12] Following preliminary proof of safety and efficacy of a candidate ...
[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 ...
By symmetry, for only successes, the 95% confidence interval is [1−3/ n,1]. The rule is useful in the interpretation of clinical trials generally, particularly in phase II and phase III where often there are limitations in duration or statistical power. The rule of three applies well beyond medical research, to any trial done n times. If 300 ...
