Capital cases involve more complex trials and multiple appeals over the average 15 years that a convict spends on death row, where the costs of solitary confinement and security are astronomical compared with the general prison population.
A guilty verdict would not of itself prove Mr Skilling's guilt, but if prosecutors are unable to win a conviction in this relatively simple case, that might not bode well for the more complex trials of the bigger fish to come.
Mr DiMasi says the increase has been caused by larger and more complex trials, a greater focus on chronic and degenerative diseases, and higher failure rates.However, the life-saving cancer drugs that feature in many of the most emotional disputes over pricing are far from typical.
Results indicate that accuracy profiles are similar in the two conditions; however, the patterns of data measuring inhibitory control, i.e., percentage of intrusion errors, are opposite in the case of verbal (intrusions decreased in more complex trials) and visuo-spatial (intrusions increased in more complex trials) material.
Most groups operated on the basis of financial reimbursement per enrolled patient, and the UK model subsequently evolved to a hybrid system for more complex trials.
Extending the utility function, one could account for situations where the restriction of the recruitment to a subpopulation increases the costs and duration of a trial and take into account that more complex clinical trial designs are more costly to implement.
As protocol designs become more complex, clinical trial durations and budgets increase.
On the other hand, more complex adaptive trials can be designed to identify the most promising treatments for specific subpopulations within a disease and tailor trial enrollment and randomization to maximize the information gained [ 10].
This has led to ever bigger and more complex patient trials.
