Do we have this problem in the US?
The United States has a history of clinical trial scandals dating as far back as the the early 1990's and of course clinical misconduct has occurred in the US involving fabrication, falsification and plagarism (FFP). A 2002 study funded by the National Institute of Health surveyed several thousand mid career scientists based in the US and discovered misconduct well beyond simple FFP.
See article entitled 'Scientists Behaving Badly' (2005) by Brian C Martinson, Melissa S Anderson and Raymind De Vires.
Also article entitled 'Research Misconduct Among Clinical Trial Staff' 2006 by Barbara K Redman, Thomas N Templin and Jon F Merz.
And the death of Jessie Gelsinger who was an 18 year old boy who fied altruistically in a 1999 clinical trial for gene therapy. Within hours of the gene therapy his organs began to fail at the University of Pennsylvania and he died days later. An investigation later revealed that the university and lead researcher in the trial stood to gain millions from the drug being tested and had ignored early warning signs.
His dad recently lectured at the Mel and Enid Zuckerman College of Public Health 10/25/17 reminding people that the safety of trial participants relies on robust oversight and the responsibility to uphold these principles falls to everyone. He touched on how the role of money and the race to be first can cloud judgment of researchers running clinical trials.
See The Daily Wildcat entitled 'Father of clinical trial victim to speak on campus'.
Lastly, do not forget that historically in the US the dishonesty of the US Department of health's treatment of poor rural African American Tuskegee (1932-72), Jonas Salk and Koprowski's vaccines on mentally disabled children in Pennsylvania and New York etc etc.
Yes its happened in The US along with many other countries. I would ask for as much information and disclosure as possible.
