The Department of Health and Human Services Office of Inspector General (OIG) recently released a report [PDF 1.8 MB] raising doubts about the FDA’s capacity to monitor the safety of clinical trials conducted in foreign countries. According to the report, the FDA needs to:
1. Improve electronic reporting: many international trials reported safety and human subjects data in database-unfriendly formats;
2. Increase the monitoring of foreign clinical trials: the FDA is 16 times less likely to inspect foreign research sites than domestic sites;
3. Look for new ways to expand FDA oversight of foreign clinical trials, including: building new agreements with national regulatory agencies and creating new oversight programs.
While the FDA agreed with all three OIG recommendations, the agency may not have the money and staff to do the job. Inspecting research sites in other countries is logistically difficult and expensive. (According to one FDA source, inspections cost “about $40,000 each”.) With a growing number of multisite trials (with subjects enrolled in different cities, countries and regions), the cost of ensuring the safety of international medical research is indeed a high one. On the other hand, the benefits of conducting trials at non-U.S. sites are enticing. In addition to easier recruitment, diverse populations, and lower financial overhead, the Association of Clinical Research Organizations (ACRO) press release insists: “globalized trials can reduce development time by more than half”. With these and other incentives, the percent of international clinical trials has doubled in the last decade. As would be expected, while the number of FDA regulated investigators in non-U.S. countries has increased by 15% each year since 2002, the number of non-U.S. subjects enrolled in international clinical trials has also grown. In the year 2008, 78% of all human subjects participating in FDA regulated clinical trials were enrolled in foreign sites.
The impact of the OIG’s report may lead to new or increased scrutiny of how these clinical trials are conducted and regulated. While some of this increased scrutiny may come from the FDA, other government agencies, including the Department of Justice (DOJ) may get involved. An advisory [PDF 532 KB] written by Kirk Ogrosky (the former Deputy Chief for Health Care Fraud in the DOJ) and attorneys at the firm of Arnold & Porter, encourages researchers to: prepare for heightened FDA inspections; strengthen internal oversight of CROs; and ensure that research-related payments “pass muster” under anticorruption laws, including the FCPA. According to Arnold & Porter, the DOJ will be interested in payments that “may have been used as an incentive to inappropriately increase subject enrollment” and will examine “differences in payments among investigators in varying locations, and between sites overseen by … local CROs”.
For its part, ACRO stands behind a July 2009 report it commissioned on the ethics and safety of international clinical trials. In addition to restating its findings, ACRO responds to the OIG report by calling for: fully funded FDA oversight, improved research infrastructure, and universal protection of human subjects, including by the standards of the International Conference on Harmonisation’s Guideline for Good Clinical Practice [E6(R1) – PDF 380 KB].
In an editorial published in The Washington Examiner, two ethicists expressed similar confidence in the safety of international research, but worried that the public might miss the fact that a disproportionately large portion of clinical research is currently conducted in the U.S. In their assessment, to effectively and fairly address global health disparities, the number of international clinical trials should (by necessity) increase in the coming years.
In the absence, however, a simultaneous and proportional increase in FDA and other oversight, the risk that foreign clinical trials may be conducted in an unsafe or unscrupulous manner will remain unknown. At the very least (rightly or wrongly), without transparent oversight, public perception may increasingly reflect the sentiments of Adil E. Shamoo in The New York Times. Shamoo, on thinking about the “potential problems” of accountability in international research and the allure for CROs, noted: “There is less liability, patient recruitment is far easier, the concept of informed consent is not well established, and it’s cheaper.”
