The objective of this article is to propose a roadmap toward transparency of clinical trials in the Americas by their prospective registration and results disclosure. This will broaden access to more complete and accurate data and facilitate evidence-informed decision-making and participation in research. Consequently, it should have a positive impact on people's health and should promote trust in health research. Existing initiatives were identified, registration of trials was analyzed following the World Health Organization (WHO) standards on trial registration, and a roadmap is proposed to address the gaps in advancing transparency. The analysis shows that, in spite of numerous regional and country initiatives, clinical trials taking place in nonEnglish-speaking parts of the Americas are underregistered. A roadmap is proposed to enhance research governance and good research practice by improving the transparency of clinical trials. The proposed roadmap includes strategies for implementing WHO international standards for trial registration, for developing international standards of public disclosure of trial results, and for a potential role of the Pan American Health Organization.

    ABSTRACT: Clinical trial registries are one of the main sources of information concerning health research interventions that have been or are being carried out throughout the world. The World Health Organization (WHO) established a minimum data set to be recorded (20 items), which was agreed upon internationally with the stakeholders, and established a network of primary and associated records. In addition to the register ClinicalTrial.Gov (of the United States of America), there are currently two primary registries in the Americas (from Brazil and Cuba) that meet WHO requirements and provide data to WHO's International Clinical Trials Registry Platform (ICTRP). Furthermore, there are important advances in the region related to the regulations, development and implementation of national registries and to the support of the ethics committees and editors to this initiative.

    ABSTRACT: While there is a considerable literature on access to essential medicines and human rights, the topic of access to reliable drug safety and effectiveness information has received little or no attention in human rights discourse. The paper argues that access to information related to clinical drug trials is a fundamental component of the right to health. This approach rejoins the claim of authors who characterize clinical drug trials as public goods. Yet, it offers also a legal and moral basis for the immediate implementation of transparency measures, regardless of more fundamental reform of drug regulation. Framing access to clinical trials data as a component of the right to health offers strong support against the argument that transparency measures may violate international trade obligations related to data secrecy and provides a basis for claiming that states have a duty to implement such measures. The paper first provides a detailed overview of the historical development of clinical trials and results reporting registries. It then analyzes the arguments invoked against mandatory trial registration and results reporting, zooming in on claims based on data secrecy obligations under TRIPS and TRIPS Plus agreements. The paper explores why registries can generally be justified under public interest exceptions in international trade agreements and how the existence of data exclusivity regimes already provides protection against ‘unfair commercial use’ of clinical trials data. In the final section of the paper, the implementation of clinical trial and results reporting registries is situated in the context of the right to health. This not only promotes individual empowerment in requesting access to relevant health information, but also suggests that states have a duty to develop reliable and publicly accountable information systems. Such systems should enable independent medical research groups and civil society in general to contribute meaningfully to publicly accountable medical research and health product development.
