Optimize Emergency Trial Pathway for Public Trust: Study
A review of 41 clinical trials conducted under the FDA exception from informed consent (EFIC) pathway shows that the pathway has been important for the completion of emergency trials and should aim to optimize respect for patients and public trust. A report from Harvard Medical School researchers published online by Health Affairs (purchase required), says the pathway is available for trials conducted on people incapacitated by life-threatening conditions with a therapeutic time window too narrow for reliable surrogate consent. The goals are to promote therapeutic innovation and encourage rigorous but ethical experimentation on that vulnerable population.
The researchers found that of the 46,964 patients enrolled in the 41 trials, 96% were enrolled without consent, and fewer than 1% withdrew before the primary endpoint. Some 8% of the 24 superiority trials demonstrated a benefit from the experimental interventions. Nearly one-third of U.S. patients in the EFIC trials were African American, well above the percentage of the general population and far above the population of clinical trial participants.
“While EFIC trials have yielded medical advances,” the journal article says, “investigators in future trials must pay better attention to managing withdrawals and ensuring fair demographic representation.”
The researchers suggest that FDA consider implementing reporting requirements that would help ensure more rigorous collection and availability of data on consent and race in EFIC trials. “Such data should help policy makers make more informed decisions about the appropriate goals and limits of clinical research in emergency settings and, in turn, improve the EFIC process,” the article concludes.
