Honoring Our Promise: Clinical Trial Data Sharing

Clinical Trials Data Sharing Word CloudWhen people enroll in clinical trials to test new drugs, devices, or other interventions, they’re often informed that such research may not benefit them directly. But they’re also told what’s learned in those clinical trials may help others, both now and in the future. To honor these participants’ selfless commitment to advancing biomedical science, researchers have an ethical obligation to share the results of clinical trials in a swift and transparent manner.

But that’s not the only reason why sharing data from clinical trials is so important. Prompt dissemination of clinical trial results is essential for guiding future research. Furthermore, resources can be wasted and people may even stand to be harmed if the results of clinical trials are not fully disclosed in a timely manner. Without access to complete information about previous clinical trials—including data that are negative or inconclusive, researchers may launch similar studies that put participants at needless risk or expose them to ineffective interventions. And, if conclusions are distorted by failure to report results, incomplete knowledge can eventually make its way into clinical guidelines and, thereby, affect the care of a great many patients [1].

Unfortunately, the timely public reporting of results has not been consistent across the clinical trials enterprise. For example, a recent analysis of 400 U.S. clinical trials [2] found that even four years after the trials had been completed, nearly 30% had failed to share results by publishing in a scientific journal or reporting in ClinicalTrials.gov, a public database maintained by NIH.

Today, the Department of Health and Human Services (HHS) proposed a rule to require public sharing of key results—the summary data—from certain clinical trials of drugs and devices regulated by the Food and Drug Administration (FDA). While such a mandate has been in place for several years [3], the proposed rule aims to clarify the requirements [4]. Summary data would include: baseline characteristics of participants, primary and secondary outcome results, and information about adverse events. With a few exceptions, such results must be submitted to ClinicalTrials.gov within one year of the time when the trial completes collection of primary outcome data.

But we at NIH are proposing to go one step further to address this important issue. Today, NIH released a draft policy for public comment to apply these data reporting requirements to all interventional clinical trials that it funds [5]. We are committed to working with NIH-supported researchers and institutions to ensure the new responsibilities in this proposed policy are understood and any unanticipated obstacles are removed.

What all this really comes down to is trust. Clinical trial participants trust that the data they provide will be used by biomedical science to advance the health of many. Researchers seek to add to the body of biomedical knowledge and can respect this commitment by promptly sharing clinical trial data.

There is also the important matter of public trust. American taxpayers trust NIH to be a good steward of their investment—and one way we can do that is to ensure that results of all our clinical trials are shared with the worldwide scientific community in an open and efficient manner. Data sharing is essential to turn even more scientific discoveries into better health at an even faster pace!

  1. This is a timely effort to continue to improve the trust of the general public trust on participation in clinical trials.

  2. It is way past time for NIH to “REQUIRE” clinical trial results be published on the clinicaltriuals.gov website. We, the taxpayer are paying for the trials, we should have a source to find the results. If the trial is funded by NIH, then results must be “required” to be published on the clinicaltrials .gov section for reporting results. I doubt that as high a percentage of trials see 30% results posted on the appropriate clinicaltrials.gov site providing fopr such posting. I have yet to find even one of the trials I have been interested in over 15 years to have results posted.
    A year is way too long a delay. May I suggest 6 months.

  3. Yes i believe your purpose that clinical trials is crucial for guiding future analysis and development of medicine (drug) and pharmaceutical firms.

  4. Looking for studies in occipital neuralgia. Migraines with auras. Pituitary microadenoma. Nonfunctional. Lower back pain facet syndrome sciatica. Lots of stuff. Hypo pituitary. Thank you

    • Thanks for your post. To find a clinical trial,a good place to start is: http://clinicaltrials.gov

      Type one of your conditions of interest into the search field, press enter, and a menu of clinical trials will appear on your computer screen. From there, you can navigate through the various trials to read the protocols, entry criteria, and other information.
