Estimates of the total average capitalized (pre launch) r&d costs needed to bring a new compound to the market varied widely, from $161 million to $4.5 billion, depending on which research phases were included in the analysis (e.g. discovery and preclinical phases were not included in 13 estimations), the therapeutic class, the drug sample. The path to approval: clinical research phases. new treatments go through the following phases of clinical research: phase o trials. first in human clinical trial (optional) with 10 to 15 healthy volunteers where small amounts of the investigational drug are given to check if the drug behaves as expected in humans.
Randomised controlled trials are becoming increasingly costly and time consuming. in 2011, royston and colleagues proposed a particular class of multi arm multi stage (mams) designs intended to speed up the evaluation of new treatments in phase ii and iii clinical trials. Clinical trials can be separated into phase i (dose finding and safety), phase ii (activity or early efficacy), phase iii (efficacy compared with current standard of care) and occasionally phase iv (postmarketing studies). a new compound would usually have to go through phase i–iii studies sequentially with all of the financial and regulatory hurdles this poses. a recent study has estimated. An average cost of a phase iii clinical trial was estimated at $255 million. six years later, a study by moore et al. published in the british medical journal showed lower numbers, with the median cost for a pivotal (usually a phase iii) clinical trial at $48 million and an interquartile range of $20 million to $102 million. The scientists also looked at how trial costs varied depending on the type of clinical trial. trials that test a drug's ability to prevent a clinically meaningful outcome, such as a heart attack, tended to have a much higher median cost ($65 million) than trials using a surrogate outcome such as high serum cholesterol (median $24 million).

For the trials in the data set, the median cost of conducting a study from protocol approval to final clinical trial report was us$3.4 million for phase i trials involving patients, $8.6 million. While conducting trials in progressive phases increases trial challenges and short term costs, this method is important to enhance safety and decrease long term costs. in fact, late trials (e.g. phase iii trials), which have a large number of subjects and are more costly, must have a strong signal from early less costly clinical trials in order.
