Encouragingly, policy makers are beginning to take notice. China, for example, has issued new regulations on clinical application of novel interventions; it requires licensing for clinics that provide unproven stem cells. India has issued guidelines on stem cell research and therapy. As noted previously in this blog, the scientific society ISSCR issued guidelines urging clinicians to offer nonvalidated stem cell interventions to patients only in the context of clinical trials designed to test safety and efficacy. Problem is (according to the article), guidelines are sporadically enforced, if that.
I think there is much more that governments and professional societies can and should do to stem this unethical conduct. Though most of these clinics are located outside of North American and Europe, some overseas clinics have reputable, North American / European scientists and clinicians on their advisory board or have partnerships with biotechnology companies that are based in North America / Europe. Examples include Stemedica (which includes several Stanford and UCSD faculty on its advisory board), and Theravitae (which has involved close collaboration with University of Pittsburgh clinicians), and Vescell (which includes Nobelist Aaron Ciechanover on its scientific advisory board). All of these companies offer stem cell interventions to large numbers of patients outside trials, and make claims that their interventions are effective when, in fact, they remain unproven.
1- Research ethics policies should condemn scientist-clinicians who travel or collaborate abroad in delivering nonvalidated, potentially risky interventions overseas outside the context of a clinical trial. Policies should state clearly the imperative of subjecting nonvalidated interventions to systematic study.
2- Institutions should not allow these clinics to trade on their reputations, and should sanction faculty members who are involved in such activities.
3- professional societies in medical fields (e.g. cardiology) and research areas (stem cells, gene transfer) should steward the standing and credibility of their research field by developing policies and standards that discourage inappropriate activities-- through social pressure-- by providing a benchmark against which the conduct of scientists and clinicians can be judged.
