In 2011 and 2012, a large stone was thrown into the pond of scientific evidence and reliability. Both Amgen and Bayer stated that they were unable to reproduce the outcomes of previous clinical trials. Amgen scientists tried to reproduce the results of 53 essential publications. Only 6 (11.3%) of them reached the expected outcome. Bayer did the same with 67 in-house projects, whose analysis revealed that only in ~20–25% of the projects matched previous findings (visual illustration).
This topic is now widely discussed and scientists are currently working to find one or more solutions to this issue. I collected several articles on the subject and I will continue. So stay tuned!
