The process of obtaining informed consent continues to be a contentious issue in clinical and public health research carried out in resource-limited settings. We sought to evaluate this process among human research participants in randomly selected active research studies approved by the School of Medicine Research and Ethics Committee at the College of Health Sciences, Makerere University.

First-in-human research has several characteristics that require special attention with respect to ethics and human subjects protections. At least some nanomedical technologies may also have characteristics that merit special attention in clinical research, as other papers in this symposium show. This paper considers how to address these characteristics in the consent form and process for FIH nanomedicine research, focusing principally on experimental nanotherapeutic interventions but also considering nanodiagnostic interventions.It is essential, as a starting point, to recognize that the consent form (...) and process are by no means the primary protectors of human subjects. Instead, consideration of the form and content of informed consent becomes relevant only after a clinical trial has been reviewed and deemed scientifically and ethically acceptable.Two convergent types of challenges to informed consent are posed by nanomedicine FIH research. First, some issues appear generally applicable to FIH research, but have specific nanomedicine implications. (shrink)

Bioethicists have long been concerned that seriously ill patients entering early phase (‘phase I’) treatment trials are motivated by therapeutic benefit even though the likelihood of benefit is low. In spite of these concerns, consent forms for phase I studies involving seriously ill patients generally employ indeterminate benefit statements rather than unambiguous statements of unlikely benefit. This seeming mismatch between attitudes and actions suggests a need to better understand research ethics committee members’ attitudes toward communication of potential benefits and risks (...) of early phase studies to potential subjects. We surveyed the members of two U.S. research ethics committees using a phase I gene transfer study scenario, and compared the results to a previous survey of potential subjects’ perceptions and attitudes toward benefit and risk for the same protocol. The results show that there is indeed a gap between the subjects’ perceptions and the committee members’ views on what is appropriate to be communicated to research subjects. This discrepancy is the product of both the commonly assumed optimism of the subjects and to a “protective pessimism” of the research ethics committee members. We discuss this discrepancy using “frameworks of trust” and demonstrate the need to incorporate these frameworks into the existing model of informed consent. (shrink)

Background: The process of obtaining informed consent continues to be a contentious issue in clinical and public health research carried out in resource-limited settings. We sought to evaluate this process among human research participants in randomly selected active research studies approved by the School of Medicine Research and Ethics Committee at the College of Health Sciences, Makerere University. Methods: Data were collected using semi-structured interviewer-administered questionnaires on clinic days after initial or repeat informed consent procedures for the respective clinical studies (...) had been administered to each study participant. Results: Of the 600 participants interviewed, two thirds (64.2 %, 385/600) were female. Overall mean age of study participants was 37.6 (SD = 7.7) years. Amongst all participants, less than a tenth (5.9 %, 35/598) reported that they were not given enough information before making a decision to participate. A similar proportion (5.7 %, 34/597) reported that they had not signed a consent form prior to making a decision to participate in the study. A third (33.7 %, 201/596) of the participants were not aware that they could, at any time, voluntarily withdraw participation from these studies. Participants in clinical trials were 50 % less likely than those in observational studies [clinical trial vs. observational; (odds ratio, OR = 0.5; 95 % CI: 0.35-0.78)] to perceive that refusal to participate in the parent research project would affect their regular medical care. Conclusions: Most of the participants signed informed consent forms and a vast majority felt that they received enough information before deciding to participate. On the contrary, several were not aware that they could voluntarily withdraw their participation. Participants in observational studies were more likely than those in clinical trials to perceive that refusal to participate in the parent study would affect their regular medical care. (shrink)

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.

New fetal therapies offer important prospects for improving health. However, having to consider both the fetus and the pregnant woman makes the risk–benefit analysis of fetal therapy trials challenging. Regulatory guidance is limited, and proposed ethical frameworks are overly restrictive or permissive. We propose a new ethical framework for fetal therapy research. First, we argue that considering only biomedical benefits fails to capture all relevant interests. Thus, we endorse expanding the considered benefits to include evidence-based psychosocial effects of fetal therapies. (...) Second, we reject the commonly proposed categorical risk and/or benefit thresholds for assessing fetal therapy research. Instead, we propose that the individual risks for the pregnant woman and the fetus should be justified by the benefits for them and the study’s social value. Studies that meet this overall proportionality criterion but have mildly unfavorable risk–benefit ratios for pregnant women and/or fetuses may be acceptable. (shrink)
