Post-trial access to drugs for rare diseases: an integrative review

Abstract

Abstract This study is an integrative literature review to analyze the scientific production about post-trial drug access by participants of clinical trials for rare diseases. The search was carried out in the Virtual Health Library, Embase, PubMed, SciELO, Scopus and Web of Science databases, covering 21 studies. Two categories emerged from the analysis: clinical research with orphan drugs and market regulation; and access to orphan drugs: background, globalization and the right to health. The first analyzes issues related to the number of patients with rare diseases, the efficacy and safety of these studies and the cost and price of medications. The second addresses the historical background of post-trial access, the globalization of clinical trials and the difficulties to ensure the right to post-trial access to orphan drugs. Few articles addressed post-trial drug access by participants with rare diseases as a central issue, which points to the importance of further studies on this subject.
