In March 1996, the General Accounting Office (GAO) issued the reportScientific Research: Continued Vigilance Critical to Protecting Human Subjects.It stated that “an inherent conflict of interest exists when physician-researchers include their patients in research protocols. If the physicians do not clearly distinguish between research and treatment in their attempt to inform subjects, the possible benefits of a study can be overemphasized and the risks minimized.” The report also acknowledged that “the line between research and treatment is not always cleartoclinicians. Controversy (...) exists regarding whether certain medical procedures should be categorized as research.”This problem currently plagues gene transfer research. A few months prior to the GAO report, an ad hoc committee appointed by National Institutes of Health (NIH) Director Harold Varmus expressed similar concerns in its assessment of NIH investment in research on gene therapy.

First-in-human clinical trials represent a critical juncture in the translation of laboratory discoveries. However, because they involve the greatest degree of uncertainty at any point in the drug development process, their initiation is beset by a series of nettlesome ethical questions [1]: has clinical promise been sufficiently demonstrated in animals? Should trial access be restricted to patients with refractory disease? Should trials be viewed as therapeutic? Have researchers adequately minimized risks? The resolution of such ethical questions inevitably turns on claims (...) about future events like harms, therapeutic response, and clinical translation. Recurrent failures in clinical translation, like Eli Lilly's Alzheimer candidate semagacestat, highlight the severe limitations of current methods of prediction. In this case, patients in the active arm of the placebo-controlled trial had earlier onset of dementia and elevated rates of skin cancer [2]. Various authoritative accounts of human research ethics state that decision-making about risk and benefit should be careful, systematic, and non-arbitrary [3]–[5]. Yet, these sources provide little guidance about what kinds of evidence stakeholders should use to ensure their estimates of such events ground responsible ethical decisions. In this article, we suggest that investigators, oversight bodies, and sponsors often base their predictions on a flawed and inappropriately narrow preclinical evidence base. (shrink)

Little if any of the scholarly literature on nanotechnology (NT) and ethics is directed at NT researchers. Many of these practitioners believe that having clear ethical guidelines for the conduct of NT research is necessary. This work attempts to provide such guidelines. While no qualitatively new ethical issues unique to NT have yet been identified, the ethical responsibilities identified below merit serious attention by NT researchers. Thirteen specific ethical responsibilities arising at three levels are identified. They are derived by applying (...) four fundamental ethical responsibilities of scientists and engineers to the specific conditions of NT research and researchers in contemporary Western societies. Since society is placing increasing importance on producing scientists and engineers who combine high technical competence with a sensitive ethical compass, study of the ethical dimension of NT, including the identified ethical responsibilities, should become a required element of the formal education of all NT researchers.

Institutional review boards and investigators are used to talking about risks of harm. Both low risks of great harm and high risks of small harm must be disclosed to prospective subjects and should be explained and categorized in ways that help potential subjects to understand and weigh them appropriately. Everyone on an IRB has probably spent time at meetings arguing over whether a three-page bulleted list of risk description is helpful or overkill for prospective subjects. Yet only a small fraction (...) of all the time and attention lavished on risk disclosure has been devoted to discussing whether and when potential benefit to subjects can reasonably be claimed and, if so, how it should be described in the consent form and process.Traditionally, IRBs and regulators have worked to ensure that clear lines can be drawn between research that, by definition, carries no potential for direct benefit — because it uses healthy volunteers or because it is not foreseeably focused on the development of treatments — and research that does have the development of effective treatments as its goal.

Developments in the last several years have sparked renewed interest in the ethics of research involving humans. Issues relating to the global extent of research and its guiding principles are of particular importance to researchers, health officials, and individual ethics committees who want a deeper and more encompassing inquire regarding the foundation and evolution of human research. This department of CQ launches a long overdue effort to explore these wider issues. Readers are invited to submit papers to Charles MacKay, 5011 (...) Worthington Drive, Bethesda, MD 20816, USA.

Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

The 21st-century translational science campaign could lead to an increase in first-in-human trials. As tests of investigational interventions move from the laboratory to human research, scientists, officials, and review committees should address ongoing concerns about the ethics of FIH trials. In this article, I describe three ethical considerations relevant to all FIH trials: the requirement for adequate preclinical research; study design safeguards; and choice of subject population. I also examine specific ethical considerations relevant to the three subject populations involved in (...) FIH research. I recommend a variety of actions that could increase subject protection and the value of the information generated in FIH trials. (shrink)
