Availability of post-trial access in clinical trials: a review of clinical trial protocols submitted to the research ethics board of the University of the Philippines Manila.

Ethics guidelines such as the Declaration of Helsinki and the CIOMS International Ethical Guidelines for Health-related Research Involving Humans require the sponsors, in cooperation with relevant stakeholders, to provide post-trial access (PTA) to intervention and knowledge, especially in clinical trials held in resource-poor regions. To date, we have very limited knowledge in terms of whether PTA is provided at all, and in what form. To partially address this current limitation, this study wished to explore whether, for which type of drugs and in what form PTA is provided in the Philippines.
