We then estimated the rate of trial failure using competing risks methods. Finally, we assessed associations with trial failure using a Cox proportional hazards model. Results A total of 1,869 urologic oncology trials were included. Of these, 225 (12.0%) failed, and 51 (2.7%) were terminated...

However, even if the targets are truly validated, many drug candidates still have high failure rate in clinical phase I, II, and III trials, which highlight the importance of drug candidate optimization process as described below. 3.2. Current drug optimization may have overemphasized one aspect ...
Mere failure in a Phase III trial alone, even with fatalities, was not the sole criterion for inclusion on this list, since numerous drugs fail pivotal trials—sometimes numerous times—before eventually generating enough positive data to garner a marketing approval. Failed candidates making the list...
In recent years, researchers have integrated more advanced POCT equipment in clinical trials to provide results faster than local labs.Clinical trials often require participants to have specific chara...
as a single failure could set a promising treatment back for years or forever. If a drug does succeed, it can be a huge boon for the company and its investors. If a drug fails at any stage in the clinical trials process it can sink a stock. As a result, drug stocks can be quite...

clinical trials is that there is frequent underreporting of outcomes in our observational datasets because they rely on billing records for adverse events. This is especially the case for non-serious outcomes such as nausea or rashes. Such underreporting would cause the estimated rate of adverse ...
It is likely that a PV rate below 10% could be achieved in each of these 16 trials if conduct was improved. Preventing PVs In order to improve trial conduct, PVs need to be identified during a clinical trial such that they can be studied and unnecessary errors can be prevented from ...
