Background. 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.
One such adaptive design is the mams trial. mams trials were first reported over 20 years ago as a way to accelerate the process of drug development.3. mams has been more commonly implemented in phase ii iii settings, although it can be applied in any trial phase. rather than a series of separate phase ii iii studies, mams trials aim to answer. 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. Estimates of total average capitalized pre launch r&d costs varied widely, ranging from $161 million to $4.54 billion (2019 us$). therapeutic area specific estimates were highest for anticancer drugs (between $944 million and $4.54 billion). The type of progressive disease at trial entry was recorded per prostate cancer clinical trials working group recommendations 54, encompassing psa only, bone only (with or without nodal disease.

New agents in oncology historically do not progress beyond early phase clinical trials, leading to the exorbitant costs and lengthy time courses associated with the drug development process 8; however, a recent study illustrated that well performing dose finding designs can have a tremendous impact on the drug development process. 9. As such it is an open question whether investment in fmri as part of phase 2 3 trials is worth the cost and challenges of ultimate clinical scale implementation, or rather whether the field should.
