RESUMEN

Some commercial firms currently sell polygenic indexes (PGIs) to individual consumers, despite their relatively low predictive power. It might be tempting to assume that because the predictive power of many PGIs is so modest, other sorts of firms-such as those selling insurance and financial services-will not be interested in using PGIs for their own purposes. We argue to the contrary. We build this argument in two ways. First, we offer a very simple model, rooted in economic theory, of a profit-maximizing firm that can gain information about a single consumer's genome. We use the model to show that, depending on the specific economic environment, a firm would be willing to pay for statistically noisy PGIs, even if they allow for only a small reduction in uncertainty. Second, we describe two plausible scenarios in which these different kinds of firms could conceivably use PGIs to maximize profits. Finally, we briefly discuss some of the associated ethics and policy issues. They deserve more attention, which is unlikely to be given until it is first recognized that firms whose services affect a large swath of the public will indeed have incentives to use PGIs.

RESUMEN

When participants enrolled in an HIV prevention trial hold a preventive misconception (PM) - expectations that experimental interventions will confer protection from HIV infection - they may engage in behaviors that increase their risk of acquiring HIV. This can raise ethical concerns about whether those enrolled in the trial understand the nature of participation and their safety. Consequently, we systematically evaluated the prevalence of PM and its association with risk behaviors in a trial examining three candidate regimens for oral HIV pre-exposure prophylaxis in which all participants received at least one antiretroviral agent. Overall, trial participants exhibited relatively high preventive expectations that may be associated with an increase in risk behaviors among men who have sex with men. In addition, we identified substantial site variability in PM that necessitates future research to uncover its source. This will allow appropriate measures to be taken to mitigate PM and help ensure that participants have an accurate understanding of the potential risks and benefits of trial participation throughout the course of a trial.

RESUMEN

Background: Organ transplantation from donors with hepatitis C viremia (HCV) to recipients without HCV (HCV D+/R-) has excellent medical outcomes. Less is known about the psychosocial impact and experiences of HCV D+/R- recipients, particularly outside of clinical trials. Methods: We conducted in-depth, semistructured interviews with 24 HCV D+/R- recipients (kidney, n = 8; lung, n = 7; liver, n = 5; heart, n = 3; simultaneous heart and kidney, n = 1) who received transplants outside of clinical trials and were treated for HCV after transplant to assess their experiences and perspectives. We used thematic analysis to analyze the interviews. Results: Interviewees' reasons for accepting an HCV D + organ were based on perceived benefits and confidence in the effectiveness of HCV treatment. The majority (62%) received HCV treatment within 1 month after transplant (range, 1 day-2 months). Most interviewees reported positive transplant outcomes, including reduced wait times and improved survival, health, physical activity, and quality of life. Overall, themes and experiences did not differ significantly between different organ transplant types. Generally, interviewees did not perceive stigma from those aware of the HCV D+ transplant; yet, disclosure was selective and a few recipients reported concerns from family members about posttransplant HCV transmission risk. Other common concerns included treatment costs and delays, which were not always anticipated by recipients. Conclusions: Our findings suggest that HCV D+/R- kidney, liver, and heart and lung transplant recipients outside of clinical trials had overall positive experiences. However, HCV transmission risk, treatments costs, and treatment delays were a source of concern that might be mitigated with targeted pretransplant education.

RESUMEN

BACKGROUND: There is limited systematic information available about the perspectives of participants enrolled in intensive combination HIV cure-related trials inclusive of an extended analytical treatment interruption (ATI). OBJECTIVE: To assess and understand experiences of people with HIV involved in a combination HIV cure-related trial with an extended ATI. METHODS: The trial included five interventions and was followed by an ATI lasting up to 52 wk. From 2022 - 2023, we conducted in-depth interviews with study participants following their extended ATIs. Interviews were audio-recorded, transcribed, and analyzed via conventional thematic analysis. RESULTS: We interviewed seven participants. The majority were male, White, and non-Hispanic, with a median age of 37 years. Trust in the research team, scientific altruism and hope of becoming a post-intervention controller were key motivators for joining the trial. Interviewees reported being satisfied with their decision to participate in the trial and the extended ATI. Most recounted feelings of worry related to viral rebound during the ATI. Participants reported both defeat and relief with ART restart. Four faced challenges with protecting partners from HIV during their ATI, such as trying to find out if their partner(s) were using pre-exposure prophylaxis. CONCLUSIONS: Our findings demonstrate potential improvements for future ATI trial participant experiences, such as more robust resources for psychosocial support and partner protections. Dedicating greater effort to understanding participant ATI experiences can inform the design of future participant-centered HIV cure trial protocols.

RESUMEN

Introduction: Numerous arguments have been advanced for broadly sharing de-identified, participant-level clinical trial data. However, data sharing in pragmatic clinical trials (PCTs) presents ethical challenges. While prior scholarship has described aspects of PCTs that raise distinct considerations for data sharing, there have been no reports of the experiences of those at the leading edge of data-sharing efforts for PCTs, including how these particular challenges have been navigated. To address this gap, we conducted interviews with key stakeholders, with a focus on the ethical issues presented by sharing data from PCTs. Methods: We recruited respondents using purposive sampling to reflect the range of stakeholder groups affected by efforts to expand PCT data sharing. Through semi-structured interviews, we explored respondents' experiences and perceptions about sharing de-identified, individual-level data from PCTs. An integrated approach was used to identify and describe key themes. Results: We conducted 40 interviews between April and September 2022. Five overarching themes emerged through analysis: (1) challenges in sharing data collected under a waiver or alteration of consent; (2) conflicting views regarding PCT patient-subject preferences for data sharing; (3) identification of respect-promoting practices beyond consent; (4) concerns about elevated risks or burdens from sharing PCT data; and (5) diverse views about the likely benefits resulting from sharing PCT data. Conclusion: Our data indicate unresolved tensions in how to fulfill the expectation to broadly share de-identified, individual-level data from PCTs, and suggest that those promulgating and implementing data-sharing policies must be sensitive to PCT-specific considerations. Future work could inform efforts to tailor data-sharing policy and practice to reflect the challenges presented by PCTs, including sharing experiences from trials that have successfully navigated these tensions.

RESUMEN

Background: Use of adaptive clinical trials, particularly adaptive platform trials, has grown exponentially in response to the coronavirus disease (COVID-19) pandemic. Implementation of these trials in low- and middle-income countries (LMICs) has been fostered through the formation or modification of transnational research partnerships, typically between research groups from LMICs and high-income countries (HICs). While these partnerships are important to promote collaboration and overcome the structural and economic disadvantages faced by LMIC health researchers, it is critical to focus attention on the multiple dimensions of partnership equity. Methods: Based on informal literature reviews and a meeting with leaders of one of the multinational COVID-19 adaptive platform trials, we describe some important considerations about research partnership equity in this context. Results: We organize these considerations into eight thematic categories: 1) epistemic structures, 2) funding, 3) ethics oversight, 4) regulatory oversight, 5) leadership, 6) post-trial access to interventions, data, and specimens, 7) knowledge translation and dissemination, and 8) research capacity strengthening and maintenance. Within each category we review normative claims that support its relevance to research partnership equity followed by discussion of how adaptive platform trials highlight new dimensions, considerations, or challenges. Conclusion: In aggregate, these observations provide insight into procedural and substantive equity-building measures within transnational global health research partnerships more broadly.

RESUMEN

Importance: Early anhydramnios during pregnancy, resulting from fetal bilateral renal agenesis, causes lethal pulmonary hypoplasia in neonates. Restoring amniotic fluid via serial amnioinfusions may promote lung development, enabling survival. Objective: To assess neonatal outcomes of serial amnioinfusions initiated before 26 weeks' gestation to mitigate lethal pulmonary hypoplasia. Design, Setting, and Participants: Prospective, nonrandomized clinical trial conducted at 9 US fetal therapy centers between December 2018 and July 2022. Outcomes are reported for 21 maternal-fetal pairs with confirmed anhydramnios due to isolated fetal bilateral renal agenesis without other identified congenital anomalies. Exposure: Enrolled participants initiated ultrasound-guided percutaneous amnioinfusions of isotonic fluid before 26 weeks' gestation, with frequency of infusions individualized to maintain normal amniotic fluid levels for gestational age. Main Outcomes and Measures: The primary end point was postnatal infant survival to 14 days of life or longer with dialysis access placement. Results: The trial was stopped early based on an interim analysis of 18 maternal-fetal pairs given concern about neonatal morbidity and mortality beyond the primary end point despite demonstration of the efficacy of the intervention. There were 17 live births (94%), with a median gestational age at delivery of 32 weeks, 4 days (IQR, 32-34 weeks). All participants delivered prior to 37 weeks' gestation. The primary outcome was achieved in 14 (82%) of 17 live-born infants (95% CI, 44%-99%). Factors associated with survival to the primary outcome included a higher number of amnioinfusions (P = .01), gestational age greater than 32 weeks (P = .005), and higher birth weight (P = .03). Only 6 (35%) of the 17 neonates born alive survived to hospital discharge while receiving peritoneal dialysis at a median age of 24 weeks of life (range, 12-32 weeks). Conclusions and Relevance: Serial amnioinfusions mitigated lethal pulmonary hypoplasia but were associated with preterm delivery. The lower rate of survival to discharge highlights the additional mortality burden independent of lung function. Additional long-term data are needed to fully characterize the outcomes in surviving neonates and assess the morbidity and mortality burden. Trial Registration: ClinicalTrials.gov Identifier: NCT03101891.

RESUMEN

Human cerebral organoids (HCOs) are model systems that enable researchers to investigate the human brain in ways that had previously been impossible. The emergence of HCOs was accompanied by both expert and layperson discussions concerning the possibility of these novel entities developing sentience or consciousness. Such concerns are reflected in deliberations about how to handle and regulate their use. This perspective article resulted from an international and interdisciplinary research retreat "Ethical, Legal and Social Aspects of Human Cerebral Organoids and their Governance in Germany, the United Kingdom and the United States", which took place in Tübingen, Germany, in August 2022. The retreat focused on whether HCO research requires new ethical and regulatory approaches. It addressed epistemic issues around the detection and theorisation of consciousness, ethical concerns around moral status and research conduct, difficulties for legislation and guidelines managing these entities, and public engagement.

RESUMEN

Human pluripotent stem cells can be used to derive in vitro models recapitulating post-implantation human embryos. While useful for research purposes, such integrated embryo models raise ethical issues that need to be addressed to facilitate ethically appropriate policies and regulations that permit scientific ingenuity and medical progress.

RESUMEN

BACKGROUND: Digitization (using novel digital tools and strategies) and consumerism (taking a consumer-oriented approach) are increasingly commonplace in clinical trials, but the implications of these changes are not well described. METHODS: We assembled a group of trial experts from academia, industry, non-profit, and government to discuss implications of this changing trial landscape and provide guidance. RESULTS: Digitization and consumerism can increase the volume and diversity of trial participants and expedite recruitment. However, downstream bottlenecks, challenges with retention, and serious issues with equity, ethics, and security can result. A "click and mortar" approach, combining approaches from novel and traditional trials with the thoughtful use of technology, may optimally balance opportunities and challenges facing many trials. CONCLUSION: We offer expert guidance and three "click and mortar" approaches to digital, consumer-oriented trials. More guidance and research are needed to navigate the associated opportunities and challenges.

RESUMEN

Educational programs are integral to building health research ethics (HRE) capacity, but no outcomes framework exists to guide them. We empirically developed a competency framework for health research ethics education-the Framework for Research Ethics Studies Competencies and Outcomes (FRESCO)-using mixed methods, including group concept mapping and a survey of international experts. FRESCO includes seven competency domains: (1) Foundational Knowledge; (2) Laws, Regulations, Guidelines, and Policies for Research Oversight; (3) Ethical-Issue Identification, Analysis, and Resolution; (4) Engagement, Communication, and Advocacy; (5) Lifelong Learning, Education, Research, and Scholarship; (6) Coordination, Stewardship, and Responsiveness in HRE Systems; and (7) Impartiality, Honesty, and Responsibility. These domains are detailed in 27 subdomains. Survey respondents rated FRESCO's relevance to HRE highly. FRESCO can be adapted and implemented in educational programs to refine recruitment and selection processes, educational and assessment methods, and performance measures to ensure that HRE educational programs have their intended effects.

RESUMEN

Fuelled by adaptations to clinical trial implementation during the COVID-19 pandemic, decentralised clinical trials are burgeoning. Decentralised clinical trials involve many digital tools to facilitate research without physical contact between research teams and participants at various stages, such as recruitment, enrolment, informed consent, administering study interventions, obtaining patient-reported outcome measures, and safety monitoring. These tools can provide ways of ensuring participants' safety and research integrity, while sometimes reducing participant burden and trial cost. Research sponsors and investigators are interested in expanding the use of decentralised clinical trials. The US Food and Drug Administration and other regulators worldwide have issued guidance on how to implement such adaptations. However, there has been little focus on the distinct ethical challenges these trials pose. In this Health Policy report, which is informed by both traditional research ethics and digital ethics frameworks, we group the related ethical issues under three areas requiring increased ethical vigilance: participants' safety and rights, scientific validity, and ethics oversight. Our aim is to describe these issues, offer practical means of addressing them, and prompt the delineation of ethical standards for decentralised trials.

RESUMEN

The need to understand the systems that support ethical health research has long been recognized, but there are limited descriptions of actual health research ethics (HRE) systems. Using participatory network mapping methods, we empirically defined Malaysia's HRE system. 13 Malaysian stakeholders identified 4 overarching and 25 specific HRE system functions and 35 actors internal and 3 external to the Malaysian HRE system responsible for those functions. Functions requiring the most attention were: advising on legislation related to HRE; optimizing research value to society; and defining standards for HRE oversight. Internal actors with the greatest potential for more influence were: the national network of research ethics committees; non-institution-based research ethics committees; and research participants. The World Health Organization, an external actor, had the largest untapped potential for influence overall. In summary, this stakeholder-driven process identified HRE system functions and actors that could be targeted to increase HRE system capacity.

RESUMEN

Public engagement is increasingly recognized as being integral to basic and translational research. Public engagement involves effective communication about research along with the mutual exchange of views and opinions among a wide variety of members in society. As such, public engagement can help to identify issues that must be addressed in order for research to be ethically sound and trustworthy. It is especially critical in research that potentially raises ethical concerns, for example research involving embryos, germline genome editing, stigmatized conditions, and marginalized communities. Therefore, it is not surprising that there have been prominent recent calls for public engagement in the emerging sciences. However, given that there is arguably little agreement about how this should be done and the best ways of doing so, those involved with planning and implementing public engagement can benefit from understanding a broad range of prior experiences on related issues.

RESUMEN

BACKGROUND: HIV molecular epidemiology (HIV-ME) is now being used in a variety of ways, including molecular HIV surveillance to help identify and respond to emerging HIV transmission clusters as specified in the Ending the HIV Epidemic in the U.S. initiative. However, HIV-ME in general, and its use for cluster detection and response, in particular, raises significant ethical and social concerns, which have spurred vigorous debates. Nevertheless, there is a paucity of information regarding how these potential benefits and concerns are perceived among people living with HIV and people without HIV at an increased risk. SETTING: Virtual engagement with US participants. METHODS: We rigorously developed a brief informational video about HIV-ME and conducted a series of in-depth interviews with people living with HIV and people without HIV at an increased risk. RESULTS: Through extensive stakeholder engagement during the video development process and subsequent in-depth interviews (N = 24), several preliminary findings surfaced. In contrast to the high level of concern raised by some critics of HIV-ME, our data appear to show broad support for it. In addition, we observed conflation of perspectives about HIV-ME with concerns about HIV public health surveillance more generally. CONCLUSION: Our experiences reveal substantial communication challenges related to the nature of HIV-ME that need to be overcome to ensure that it is properly understood, which is necessary for meaningfully engaging stakeholders in discussions about its use. Moreover, ongoing, responsive, engagement efforts are critical. Additional systematic data are needed to help inform policy making and practice regarding HIV-ME.

RESUMEN

Clinicians have good moral and professional reasons to contribute to pragmatic clinical trials (PCTs). We argue that clinicians have a defeasible duty to participate in this research that takes place in usual care settings and does not involve substantive deviation from their ordinary care practices. However, a variety of countervailing reasons may excuse clinicians from this duty in particular cases. Yet because there is a moral default in favor of participating, clinicians who wish to opt out of this research must justify their refusal. Reasons to refuse include that the trial is badly designed in some way, that the trial activities will violate the clinician's conscience, or that the trial will impose excessive burdens on the clinician.
