Articles on Patients’ Rights in Clinical Trials:

“The hard way to a Bill of Rights.” (editorial) The Lancet Neurology. December 2005, Vol.4: p.787  Read full text of the editorial.

Patient choice in clinical trials. (editorial) Lancet; 6/11/2005, Vol. 365 Issue 9476, p1984.
"..This case highlights several important clinical issues, but chief among these is patient choice. Amgen reacted responsibly to potential safety risks of a treatment with uncertain benefit by stopping the trial. But in looking for a consistent effect among the population of participants, the company could not exclude the potential benefit of the therapy to some individuals. The fact that the case has ended up in the courts highlights the lack of a suitable mechanism through which evidence from individuals can be taken into account in decision-making about experimental treatments. The case also shows that although patient choice has become a mantra for health services, when it comes to setting the research agenda, patients have barely any involvement at all...."
