Individual and public interests in clinical research during epidemics: a reply to Calain : In response to: Calain P. The Ebola clinical trials: a precedent for research ethics in disasters

A systematic literature review of the ethics of conducting research in the humanitarian setting

Background

Research around humanitarian crises, aid delivery, and the impact of these crises on health and well-being has expanded dramatically. Ethical issues around these topics have recently received more attention. We conducted a systematic literature review to synthesize the lessons learned regarding the ethics of research in humanitarian crises.

Methods

We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines to identify articles regarding the ethics of research in humanitarian contexts between January 1, 1997 and September 1, 2019. We analyzed the articles to extract key themes and develop an agenda for future research.

Results

We identified 52 articles that matched our inclusion criteria. We categorized the article data into five categories of analysis: 32 were expert statements, 18 were case studies, 11 contained original research, eight were literature reviews and three were book chapters. All included articles were published in English. Using a step-wise qualitative analysis, we identified 10 major themes that encompassed these concepts and points. These major themes were: ethics review process (21 articles, [40.38%]); community engagement (15 articles [28.85%]); the dual imperative, or necessity that research be both academically sound and policy driven, clinical trials in the humanitarian setting (13 articles for each, [25.0%)]; informed consent (10 articles [19.23%]); cultural considerations (6 articles, [11.54%]); risks to researchers (5 articles, [9.62%]); child participation (4 articles [7.69%]); and finally mental health, and data ownership (2 articles for each [3.85%]).

Conclusions

Interest in the ethics of studying humanitarian crises has been dramatically increasing in recent years. While key concepts within all research settings such as beneficence, justice and respect for persons are crucially relevant, there are considerations unique to the humanitarian context. The particular vulnerabilities of conflict-affected populations, the contextual challenges of working in humanitarian settings, and the need for ensuring strong community engagement at all levels make this area of research particularly challenging. Humanitarian crises are prevalent throughout the globe, and studying them with the utmost ethical forethought is critical to maintaining sound research principles and ethical standards.

The Plasma Mobile, 'A gift from heaven': The impact of health technology transfer on trial perceptions and expectations during the Ebola-Tx Trial, Conakry

During the West African Ebola Virus Disease (EVD) epidemic from 2014 to 2016, a variety of technologies travelled considering the context of the emergency: a highly contagious fast-killing disease outbreak with no known remedy and a rapidly increasing number of cases. The Ebola-Tx clinical trial tested the efficacy of Convalescent Plasma (CP) as a treatment for EVD in Guinea. This paper is based on ethnographic research in the Ebola-Tx trial and focuses on the introduction of a mobile plasma collection centre, referred to as the 'Plasma Mobile', equipped with plasmapheresis and pathogen inactivation technologies, as well as how the transfer itself of this technology entailed complex effects on CP donors as trial participants (i.e. providers of the therapeutic product), directly involved staff and more broadly on the trial implementation as a whole. The transfer led to the emergence of a dimension of hope as CP donors hoped that the plasma would cure and, as providers of the therapeutic, hoped it would decrease their stigmatization and the economic impact of the disease. We conclude that, in light of the intricate effects that the transfer of such health technology can entail-in the localization to the specific context, as well as in the consequences they can have on actors involved in the implementation of such technologies-global health technologies should be put at the services of next epidemic and pandemic (preparedness) on condition that they are accompanied by an understanding of the technologies' own cultural meanings and social understandings.

Research Ethics Committees (RECs) and epidemic response in low and middle income countries

The recent Ebola and Zika virus epidemics in some parts of Africa and Asia have showcased the porosity in disaster preparedness and response, not only in the affected countries, but on a global scale. For the Ebola epidemic, scientifically robust research was started late during the course of the epidemic, with waste of resources and lost research opportunities. Research Ethics Committees have a significant role to play with regards to epidemic response for the future. This paper presents key challenges and opportunities for ethics review during emergencies, specifically for low and middle income countries. There is no better moment to test the efficacy and safety of drugs or vaccines for infected, or at risk populations than during the disaster itself. The main mantras that form the back bone of research ethics review (Helsinki Declaration, the CIOMS International Ethical Guidelines for Biomedical Research Involving Human Subjects, WHO and the ICH guidelines for Good Clinical Practice) are increasingly showing their limitations. Most protocols are generally from developed countries where the funding originates. Not only is the direct transposition to Low and Middle Income Country (LMIC) settings inappropriate on its own, also, using such guidelines in times of public health disasters might be time consuming, and might also lead to wastage of research opportunities, especially when sociocultural peculiarities, and anthropological research arms are completely excluded or avoided within the care and research packages. Governments should include RECs as key members during the elaboration, and daily functioning of their national public emergency response packages. Developing simple research ethics review guidelines, involvement of health care staff in ethics training, community mobilization, and incorporation of anthropological research during the medical response, research and communication phases, are imperatives in epidemic response.

[Diagnosis and treatment of emerging viral diseases : how can we do better ?]

Virus emergence episodes follow one another at a steady pace. The medical and scientific community responds to needs as and when they arise but finds difficult to propose a global strategy in the medium and long term. Regarding diagnosis, priority should be given to anticipating the management of re-emerging pathogens, to developing capacities of real-time molecular diagnosis, and to preserving reference expertise and reference biological materials. This effort should also include sero-epidemiological studies aiming at obtaining a more accurate mapping of the circulation of potentially re-emerging pathogens. Regarding therapeutics (with the exception of vaccines which are addressed in another presentation), the expected improvements are the advance implementation of ready-to-use protocol frames for clinical trials and that of an ambitious strategy aiming at gradually covering the taxonomic spectrum of evolutionary virus groups infecting vertebrates.
