El equívoco terapéutico en los ensayos clínicos: combatirlo y convivir con él

Participant-funded clinical trials on rare diseases

The development of medicines for certain rare diseases can be cut short by lack of funding. In certain cases the patients themselves, or their relatives, occasionally fund the clinical trial in which they will be treated with the investigational medicine. There are three models of self-funded clinical research: two of them, 'pay to try' and 'pay to participate', have already been put into practice. The third, the 'plutocratic' proposal, which has been recently put forward is still a theoretical model. In this work the scientific, social and ethical benefits and risks of the two clinical research models, 'pay to participate and the 'plutocratic' proposal, are reviewed. Patient-funded clinical trials are frequently performed through crowdfunding. The most controversial aspects of this funding modality are also addressed in this article from several perspectives. Finally, a future scenario that would allow the launching of self-funded clinical trials in Spain by the 'plutocratic' proposal is proposed.

Indirect Benefits in HIV Cure Clinical Research: A Qualitative Analysis

Currently, much of early phase HIV cure research involves unknown and potentially serious risks, with little or no chance of direct health benefits. During informed consent, researchers emphasize this lack of personal medical benefit to minimize misconceptions that undermine genuine consent. We explored participants' and researchers' perspectives on HIV cure clinical research participation and its potential benefits. We conducted semistructured interviews with 17 HIV cure research participants and nine researchers in North Carolina, USA. We analyzed interviews to identify participant experience-related themes. We were particularly interested in indirect benefits, such as psychological support or improved care. We also assessed five consent documents for benefit/risk-related language. Research participants were male, with a median age of 50 (range: 28-62); most were non-Hispanic white (15/17) and men who have sex with men (13/17). All 17 trial participants found research participation meaningful and beneficial. Reported benefits included improved healthcare (16/17), HIV knowledge (13/17), intimate relationships (10/17), and positive behaviors (6/17). In addition, all participants described psychological benefits, including increased positive outlook, improved sense of purpose, emotional support, and enriched self-image. Participants reported risks such as quality of life concerns, uncomfortable procedures (e.g., leukapheresis), latency reversal, and HIV status disclosure. While the consent documents included discussion of these and other risks, they did not mention potential indirect benefits. Individuals involved in HIV clinical research have recognized participant psychological, social, and behavioral benefits. We recommend that researchers and institutional review boards consider these benefits for inclusion during risk/benefit assessments, consent procedures, and other discussions with prospective participants.

Decision Making in the PICU: An Examination of Factors Influencing Participation Decisions in Phase III Randomized Clinical Trials

Background. In stressful situations, decision making processes related to informed consent may be compromised. Given the profound levels of distress that surrogates of children in pediatric intensive care units (PICU) experience, it is important to understand what factors may be influencing the decision making process beyond the informed consent. The purpose of this study was to evaluate the role of clinician influence and other factors on decision making regarding participation in a randomized clinical trial (RCT). Method. Participants were 76 children under sedation in a PICU and their surrogate decision makers. Measures included the Post Decision Clinician Survey, observer checklist, and post-decision interview. Results. Age of the pediatric patient was related to participation decisions in the RCT such that older children were more likely to be enrolled. Mentioning the sponsoring institution was associated with declining to participate in the RCT. Type of health care provider and overt recommendations to participate were not related to enrollment. Conclusion. Decisions to participate in research by surrogates of children in the PICU appear to relate to child demographics and subtleties in communication; however, no modifiable characteristics were related to increased participation, indicating that the informed consent process may not be compromised in this population.
