If, as is alleged, challenge trials of vaccines against COVID-19 are likely to save thousands of lives and vastly diminish the economic and social harms of the pandemic while subjecting volunteers to risks that are comparable to kidney donation, then it would seem that the only sensible objection to such trials would be to deny that they have low risks or can be expected to have immense benefits. This essay searches for a philosophical rationale for rejecting challenge trials while supposing (...) that they have huge benefits and relatively low risks. Although it finds some force in objections to challenge trials grounded in the obligations of researchers to limit the harms imposed on some individuals for the benefit of others, it argues that there is no compelling objection to challenge trials of vaccines for COVID-19—if they have the benefits and risks that have been claimed.

Much of the human research conducted in the United States or by U.S. researchers is regulated by the Common Rule. The Common Rule reflects the decision of 17 federal agencies, including the Department of Health and Human Services, to require that investigators follow the same rules for conducting human research., though there is significant overlap with the Common Rule.) Many of the obligations delineated in the Common Rule can be traced back to the work of the National Commission for the (...) Protection of Human Subjects of Biomedical and Behavioral Research. The National Commission was appointed in 1974 as part of the National Research Act in response to revelations about serious abuses involving human subjects, most notably the Tuskegee/United States Public Health Service Syphilis Study.

How should the definition of “minimal risk” in the federal research regulations be interpreted in regard to pregnant women and fetuses? Surprisingly, there has been little discussion of this question. There is, after all, a substantial amount of published work addressing the question of how “minimal risk” should be interpreted. Similarly, there is a large body of literature on the ethics of research involving pregnant women and fetuses, particularly maternal-fetal surgery. However, in neither of these bodies of work can one (...) find an analysis of minimal risk in regard to fetuses or pregnant women.The concept of minimal risk is defined in the regulations as follows:Minimal risk means that the probability and magnitude of harm or discomfort anticipated in the research are not greater in and of themselves than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests.

In this issue of the Journal of Law, Medicine & Ethics Peter Clark provides a comprehensive and sound ethical analysis of clinical trials examining the treatment of advanced Parkinson's disease with fetal tissue transplantation. These studies raise profound questions about how clinical trials of surgical interventions ought to be conducted. At stake is not only the ethical basis of such trials, but differing views as to the proper role of science in medicine and its limitations.Experience with the broader debate on (...) the ethical permissibility of placebo controls has taught us that the choice of control treatment is an aspect of trial design in which ethical and scientific issues overlap. Accordingly, I will highlight, and perhaps expand upon, three issues raised by Clark: What scientific questions ought clinical trials of surgical interventions ask? How should the ethical analysis of risk for such trials be conceived? And, are surgical patients a vulnerable population? (shrink)

Here we identify approximately 40,000 healthy human volunteers who were intentionally exposed to infectious pathogens in clinical research studies dating from late World War II to the early 2000s. Microbial challenge experiments continue today under contemporary human subject research requirements. In fact, we estimated 4,000 additional volunteers who were experimentally infected between 2010 and the present day. We examine the risks and benefits of these experiments and present areas for improvement in protections of participants with respect to safety. These are (...) the absence of maximum limits to risk and the potential for institutional review boards to include questionable benefits to subjects and society when weighing the risks and benefits of research protocols. The lack of a duty of medical care by physician–investigators to research subjects is likewise of concern. The transparency of microbial challenge experiments and the safety concerns raised in this work may stimulate further dialogue on the risks to participants of human experimentation. (shrink)

Most medical research and a substantial amount of non-medical research, especially that involving human participants, is governed by some kind of research ethics committee (REC) following the recommendations of the Declaration of Helsinki for the protection of human participants. The role of RECs is usually seen as twofold: firstly, to make some kind of calculation of the risks and benefits of the proposed research, and secondly, to ensure that participants give informed consent. The extent to which the role of the (...) REC includes the former is not uncontroversial. Indeed, the most prevalent debate on the role of RECs sees liberals and strong paternalists arguing over the importance of informed consent given by competent agents versus the significance of making benevolent decisions on behalf of others. On the one hand, liberals argue for the rights of competent adults to decide for themselves the kinds and extents of risks to which they wish to expose themselves. On the other hand, proponents of strong paternalism raise concerns about the likelihood of participants being able to truly understand the complex data involved in research. They support a role for RECs in which they exercise duties of benevolence towards patients and participants by limiting the extent to which they can be exposed to significant, permanent and irreversible harms. In this paper, we will argue that when it comes to decisions about risk it is neither possible nor desirable for RECs to adopt either role. (shrink)

The main question explored by the book is: How can cross-border access to human genetic resources, such as blood or DNA samples, be governed in such a way as to achieve equity for vulnerable populations in developing countries? The book situates the field of genomic and genetic research within global health and research frameworks, describing the concerns that have been raised about the potential unfairness in exchanges during recent decades. Access to and sharing in the benefits of human biological resources (...) are aspects not regulated by any international legal framework such as the Convention on Biological Diversity, which applies only to the exchange of plants, animals and microorganisms, as well as to associated traditional knowledge. Examples of genetic research perceived as exploitative are provided in order to illustrate the legal vacuum concerning the global governance of human genetic resources. The main conclusions drawn from the legal and ethical analysis are: - Benefit sharing is crucial in order to avoid the exploitation of developing countries in human genetic research. - With functioning research ethics committees, undue inducement is less of a concern in genetic research than in other areas of medical research (e.g. clinical trials). - Concerns remain over research involving indigenous populations; accordingly, recommendations are provided. In drawing these conclusions, the book addresses in detail a highly pressing topic in global bioethics and international law. In this regard, it combines bioethical arguments with jurisprudence, in particular with reference to the law of equity and the legal concepts of duress (coercion), unconscionable dealing, and undue inducement.

In this paper, we defend the ethics of clinical research against the charge of paternalism. We do so not by denying that the ethics of clinical research is paternalistic, but rather by defending the legitimacy of paternalism in this context. Our aim is not to defend any particular set of paternalistic restrictions, but rather to make a general case for the permissibility of paternalistic restrictions in this context. Specifically, we argue that there is no basic liberty-right to participate in clinical (...) research and that considerations of distributive fairness justify some paternalistic protections of research subjects.

This thesis is a contribution to the ethical justification for clinical research with children. A research subject’s participation in a trial is usually justified, in part, by informed consent. Informed consent helps to uphold the moral principle of respect for persons. But children’s limited ability to make informed choices gives rise to a problem. It is unclear what, if anything, justifies their participation in research. Some research ethicists propose to resolve this problem by appealing to social utility, proxy consent, arguments (...) explaining why it is permissible to expose children to some harm, and an argument concerning the appropriate balance between research harms and benefits. I argue that each of these is a necessary part of the justification for research with children, but that the argument concerning harms and benefits is under-developed. It relies on the concept of minimal risk, but minimal risk is inadequately justified. I propose an interpretation of minimal risk. I defend the idea that minimal risk should be interpreted according to the risks of daily life. I reject the most prominent defense of daily life, which claims that daily risks are morally relevant because they replace, rather than add to, the risks a child would ordinarily face. Instead, I propose that these risks are part of a reasonable trade-off between personal safety and our ability to pursue meaningful lives. I then examine whose daily life should be captured in the concept of minimal risk. I reject arguments that minimal risk should refer to healthy children or the subjects of the research and propose instead that the referent should be children who are not unduly burdened by their lives. I argue that children are not unduly burdened when they fare well and defend the idea that children fare well when they possess sufficiently high degrees of the substantive goods of childhood. I conclude by analyzing a controversial case study using my interpretation of minimal risk. I draw on this case to argue that my interpretation offers clear guidance for research ethics review and contributes to a determination that is more plausible than its rivals. (shrink)

Risk–benefit assessment is a routine requirement for research ethics committees that review and oversee biomedical research with human subjects. Nevertheless, it remains unclear how to weigh and balance risks to research participants against the social benefits that flow from generating biomedical knowledge. In this article, we address the question of whether there are any reasonable criteria for defining the limit of permissible risks to individuals who provide informed consent for research participation. We argue against any a priori limit to permissible (...) research risks. However, attention to the uncertainty of potential social benefit that can be derived from any particular study warrants caution in exposing prospective research participants to a substantial likelihood of serious harm.

There is an alleged tension between undue inducement and exploitation in research trials. This paper considers claims that increasing the benefits to research subjects enrolled in international, externally-sponsored clinical trials should be avoided on the grounds that it may result in the undue inducement of research subjects. This article contributes to the debate about exploitation versus undue inducement by introducing an analysis of the available empirical research into research participants' motivations and the influence of payments on research subjects' behaviour and (...) risk assessment. Admittedly, the available research in this field is limited, but the research that has been conducted suggests that financial rewards do not distort research subjects' behaviour or blind them to the risks involved with research. Therefore, I conclude that research sponsors should prioritise the prevention of exploitation in international research by providing greater benefits to research participants. (edited). (shrink)

Background Ethics committees typically apply the common principles of autonomy, nonmaleficence, beneficence and justice to research proposals but with variable weighting and interpretation. This paper reports a comparison of ethical requirements in an international cross-cultural study and discusses their implications. Discussion The study was run concurrently in New Zealand, UK, Israel, Canada and USA and involved testing hypotheses about believability of testimonies regarding alleged child sexual abuse. Ethics committee requirements to conduct this study ranged from nil in Israel to considerable (...) amendments designed to minimise participant harm in New Zealand. Assessment of minimal risk is a complex and unreliable estimation further compounded by insufficient information on probabilities of particular individuals suffering harm. Estimating potential benefits/ risks ratio and protecting participants' autonomy similarly are not straightforward exercises. Summary Safeguarding moral/humane principles should be balanced with promotion of ethical research which does not impede research posing minimal risk to participants. In ensuring that ethical standards are met and research has scientific merit, ethics committees have obligations to participants (to meet their rights and protect them from harm); to society (to ensure good quality research is conducted); and to researchers (to treat their proposals with just consideration and respect). To facilitate meeting all these obligations, the preferable focus should be promotion of ethical research, rather than the prevention of unethical research, which inevitably results in the impediment of researchers from doing their work. How the ethical principles should be applied and balanced requires further consideration. (shrink)

An informed consent and voluntary assent in biomedical research with adolescents is contingent on a variety of factors, including adolescent and parent perceptions of research risk, benefit, and decision-making autonomy. Thirty-seven adolescents with asthma and their parents evaluated a high or low aversion form of a pediatric asthma research vignette and provided an enrollment decision; their perceptions of family influence over the participation decision; and evaluations of risk, aversion, benefit, and burden of study procedures. Adolescents and their parents agreed on (...) research participation decisions 74% of the time, yet both claimed ultimate responsibility for the participation decision. Both rated most study procedures as significantly more aversive than risky. Parents were more likely to rate aspects of the hypothetical study as beneficial and to provide higher risk ratings for procedures. Disagreements concerning research participation decisions and decision-making autonomy have implications for the exercise of voluntary assent in biomedical research. (shrink)

This article describes our efforts to screen and enrol clinical trial participants conscientiously in the COVID-19 pandemic setting. We present the standard screening and enrolment process prior to, and our process of adapting to, the pandemic. Our goal was to develop a way to screen and enrol people for clinical trials that was both equitable and effective. In addition, we outline the steps our research department took to ensure that ethical, clinical and logistical factors were considered when matching a patient (...) to a clinical trial. (shrink)

The use of placebo controls in surgical research, or ‘sham surgery’ as it sometimes described, raises a number of ethical issues. Despite such issues, sham surgery is presently being employed, albeit very rarely, in surgical research. In this paper, the ethical implications of such control groups are discussed in the context of research into various conditions, including Parkinson's Disease and arthritis. Conflicting ethical considerations include: i) patients' best interests in relation to the harms and risks involved; ii) the need for (...) more rigorous methods in surgical research, and iii) the question of patient autonomy. Contextual features which may influence the ethical acceptability of a specific sham-controlled surgical trial are discussed. (shrink)

The leading ethical position on placebo-controlled clinical trials is that whenever proven effective treatment exists for a given condition, it is unethical to test a new treatment for that condition against placebo. Invoking the principle of clinical equipoise, opponents of placebo-controlled trials in the face of proven effective treatment argue that they (1) violate the therapeutic obligation of physicians to offer optimal medical care and (2) lack both scientific and clinical merit. We contend that both of these arguments are mistaken. (...) Clinical equipoise provides erroneous ethical guidance in the case of placebo-controlled trials, because it ignores the ethically relevant distinction between clinical trials and treatment in the context of clinical medicine and the methodological limitations of active-controlled trials. Placebo controls are ethically justifiable when they are supported by sound methodological considerations and their use does not expose research participants to excessive risks of harm. (shrink)

ABSTRACT In this paper, I support the claim that placing certain restrictions on public access to possible new treatments is morally problematic under some exceptional circumstances. Very ill patients may find that all available standard treatments are unacceptable, either because they are ineffective or have serious adverse effects, and these patients may understandably be desperate to try something new even if this means stepping into the unknown. Faced with certain death, it is rational to want to try something new and (...) to chance a dire outcome. Restricting possible new treatments to research trials may put these treatments scientifically, geographically or economically out of reach of these patients. For those who can get access, research restrictions could weaken, though not necessarily eliminate, the value of consent participants of such trials are able to give. Some participants may therefore be exploited for scientific purposes in the name of public interest. There are nonetheless compelling reasons for keeping some restrictive regulation in this area.

BackgroundResearch ethics committees (RECs) are tasked to assess the risks and the benefits of a trial. Currently, two procedure-level approaches are predominant, the Net Risk Test and the Component Analysis.DiscussionBy looking at decision studies, we see that both procedure-level approaches conflate the various risk-benefit tasks, i.e., risk-benefit assessment, risk-benefit evaluation, risk treatment, and decision making. This conflation makes the RECs’ risk-benefit task confusing, if not impossible. We further realize that RECs are not meant to do all the risk-benefit tasks; instead, (...)

Non-beneficial paediatric research is vital to improving paediatric healthcare. Nevertheless, it is also ethically controversial. By definition, subjects of such studies are unable to give consent and they are exposed to risks only for the benefit of others, without obtaining any clinical benefits which could compensate those risks. This raises ethical concern that children participating in non-beneficial research are treated instrumentally; that they are reduced to mere instruments for the benefit of science and society. But this would make the research (...) incompatible with the widely endorsed principle of the primacy of the human subject, which stipulates that the interests of the participating individual should prevail over the interests of science and society. This paper deals with this conflict. It analyses solutions to this problem developed in the literature, and shows that they are unsuccessful. Finally, it offers a new idea of how to reconcile the conduct of non-beneficial paediatric research with the PP. The paper argues for a new formula of the PP, and shows that it implies a specific non-comparative definition of the minimal risk threshold. (shrink)

Background South Africa is likely to be the first country in the world to host an adolescent HIV vaccine trial. Adolescents may be enrolled in late 2007. In the development and review of adolescent HIV vaccine trial protocols there are many complexities to consider, and much work to be done if these important trials are to become a reality. Discussion This article sets out essential requirements for the lawful conduct of adolescent research in South Africa including compliance with consent requirements, (...) child protection laws, and processes for the ethical and regulatory approval of research. Summary This article outlines likely complexities for researchers and research ethics committees, including determining that trial interventions meet current risk standards for child research. Explicit recommendations are made for role-players in other jurisdictions who may also be planning such trials. This article concludes with concrete steps for implementing these important trials in South Africa and other jurisdictions, including planning for consent processes; delineating privacy rights; compiling information necessary for ethics committees to assess risks to child participants; training trial site staff to recognize when disclosures trig mandatory reporting response; networking among relevant ethics commitees; and lobbying the National Regulatory Authority for guidance.

Conducting research with vulnerable populations involves careful attention to the interests of individuals. Although it is generally understood that informed consent is a necessary prerequisite to research participation, it is less clear how to proceed when potential research participants lack the capacity to provide this informed consent.

Practical guidelines for recruitment of and data collection from people in the middle or (...) late stage of dementia are proposed. These guidelines were used by research assistants in a minimal risk study. (shrink)

Non-therapeutic research with imminently dying patients in intensive care presents complex ethical issues. The vulnerabilities of the imminently dying, together with societal disquiet around death and dying, contribute to an intuition that such research is beyond the legitimate scope of scientific inquiry. Yet excluding imminently dying patients from research hinders the advancement of medical science to the detriment of future patients. Building on existing ethical guidelines for research, we propose a framework for the ethical design and conduct of research involving (...) the imminently dying. To enable rapid translation to practice, we frame the approach in the form of eight ethical questions that researchers and research ethics committees ought to answer prior to conducting any research with this patient population. (1) Does the study hypothesis require the inclusion of imminently dying patients? (2) Are non-therapeutic risks and burdens minimised consistent with sound scientific design? (3) Are the risks of these procedures no more than minimal risk? (4) Are these non-therapeutic risks justified insofar as they are reasonable in relation to the anticipated benefits of the study? (5) Will valid informed consent be obtained from an authorised surrogate decision maker? (6) How will incidental findings be handled? (7) What additional steps are in place to protect families and significant others of research participants? (8) What additional steps are in place to protect clinical staff and researchers? Several ethical challenges hinder research with imminently dying patients. Nonetheless, provided adequate protections are in place, non-therapeutic research with imminently dying patients is ethically justifiable. Applying our framework to an ongoing study, we demonstrate how our question-driven approach is well suited to guiding investigators and research ethics committees. (shrink)

Ethics in research are norms for conduct based on local regulations and universal recommendations such as the Nuremberg Code or the Declaration of Helsinki. However, these documents have a number of shortcomings that thwart the construction of a comprehensive ethical framework to guide research on humans in an effort to make better use of research results and to provide for ethical construction of knowledge. A broader ethical framework is suggested in this article, consistent with Ezekiel J. Emanuel's proposal, specifically one (...) that allows for evaluation, reflection and debate about scientific research on humans, based on eight fundamental principles. (shrink)
