Justice and the human development approach to international research.

The debate over when medical research may be performed in developing countries has steered clear of the broad issues of social justice in favor of what seem more tractable, practical issues. A better approach will reframe the question of justice in international research in a way that makes explicit the links between medical research, the social determinants of health, and global justice.

Placebos that harm: sham surgery controls in clinical trials

Recent debates over the use of sham surgery as a control for studies of fetal tissue transplantation for Parkinson’s disease have focused primarily on rival interpretations of the US federal regulations governing human-subjects research. Using the core ethical and methodological considerations that underwrite the equipoise requirement, we find strong prima facie reasons against using sham surgery as a control in studies of cellular-based therapies for Parkinson’s disease and more broadly in clinical research. Additionally, we believe that these reasons can be generalized to apply to the use of other placebo controls that carry significant risks of positive harms in and of themselves. As a result, our arguments are centrally relevant to the emerging drive to subject therapies with a surgical component to the same rigorous standards of evaluation as those governing the approval of new pharmaceuticals.

Predicting Harms and Benefits in Translational Trials: Ethics, Evidence, and Uncertainty

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 Lillys 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.

Equipose and International Human‐Subjects Research

This paper examines the role of equipoise in evaluating international research. It distinguishes two possible formulations of the equipoise requirement that license very different evaluations of international research proposals. The interpretation that adopts a narrow criterion of similarity between clinical contexts has played an important role in one recent controversy, but it suffers from a number of problems. An alternative interpretation that adopts a broader criterion of similarity does a better job of avoiding both exploitation of the brute fact of social deprivation and the exploitation of needy populations for the benefit of more well-off populations. It also holds out the promise of reconciling the need to find interventions that can be employed in developing world contexts with the cluster of moral values that must constrain the way such research is carried out.

Beyond Access vs. Protection in Trials of Innovative Therapies

Review of first-in-human trials should safeguard the integrity of the scientific enterprise through a focus on preclinical and clinical study quality. Over the past decade, researchers have initiated innovative, early-phase, clinical trials, including the first-ever testing in humans of cell therapies for myocardial infarction (1), as well as transplantation of embryo-derived tissues for spinal cord repair (2). The next decade promises more initiatives involving first-in-human trials of innovative therapeutic strategies (3).

Research at the Auction Block: Problems for the Fair Benefits Approach to International Research

The “fair benefits” approach to international research is designed to produce results that all can agree are fair without taking a stand on divisive questions of justice. But its appealing veneer of collaboration masks ambiguities at both a conceptual and an operational level. An attempt to put it into practice would look a lot like an auction, leaving little reason to think the outcomes will satisfy even minimal conditions of fairness.

Ethical considerations in the conduct of electronic surveillance research.

The extant clinical literature indicates profound problems in the assessment, monitoring, and documentation of care in long-term care facilities. The lack of adequate resources to accommodate higher staff-to-resident ratios adds additional urgency to the goal of identifying more cost-effective mechanisms to provide care oversight. The ever expanding array of electronic monitoring technologies in the clinical research arena demands a conceptual and pragmatic framework for the resolution of ethical tensions inherent in the use of such innovative tools. CareMedia is a project that explores the utility of video, audio and sensor technologies as a continuous real-time assessment and outcomes measurement tool. In this paper, the authors describe the seminal ethical challenges encountered during the implementation phase of this project, namely privacy and confidentiality protection, and the strategies employed to resolve the ethical tensions by applying principles of the interest theory of rights.

Launching Invasive, First-in-Human Trials against Parkinson’s Disease: Ethical Considerations

The decision to initiate invasive, first‐in‐human trials involving Parkinsons disease presents a vexing ethical challenge. Such studies present significant surgical risks, and high degrees of uncertainty about intervention risks and biological effects. We argue that maintaining a favorable risk‐benefit balance in such circumstances requires a higher than usual degree of confidence that protocols will lead to significant direct and/or social benefits. One critical way of promoting such confidence is through the application of stringent evidentiary standards for preclinical studies. We close with a series of recommendations for strengthening the internal and external validity of preclinical studies, reducing their tendency toward optimism and publication biases, and improving the knowledge base used to design and evaluate preclinical studies.

The Ethics of Advertising for Health Care Services

Advertising by health care institutions has increased steadily in recent years. While direct-to-consumer prescription drug advertising is subject to unique oversight by the Federal Drug Administration, advertisements for health care services are regulated by the Federal Trade Commission and treated no differently from advertisements for consumer goods. In this article, we argue that decisions about pursuing health care services are distinguished by informational asymmetries, high stakes, and patient vulnerabilities, grounding fiduciary responsibilities on the part of health care providers and health care institutions. Using examples, we illustrate how common advertising techniques may mislead patients and compromise fiduciary relationships, thereby posing ethical risks to patients, providers, health care institutions, and society. We conclude by proposing that these risks justify new standards for advertising when considered as part of the moral obligation of health care institutions and suggest that mechanisms currently in place to regulate advertising for prescription pharmaceuticals should be applied to advertising for health care services more broadly.

Improving Ethical Review of Research Involving Incentives for Health Promotion

Alex London and colleagues propose new ethical frameworks for evaluating the risks associated with research in which financial or other incentives are used to promote healthy behavior.
