The effect of the COVID-19 pandemic on US Food and Drug Administration-funded clinical trials and natural history studies for rare diseases

Abstract

BackgroundSince 1983, the Orphan Product Grants Program, administered by the US Food and Drug Administration, provides funding for clinical trials and natural history studies in rare diseases. The COVID-19 pandemic created new challenges in rare disease product development. This study sought to determine the effects of the pandemic on rare disease studies using data from grantees of this program, and determine lessons learned that can potentially be applied to future trials in rare diseases. MethodsAll grants that were being funded by the Orphan Products Grants Program between March 2020 and March 2021 were included in the study. Data was gathered from grantees and described the effects of the pandemic on multiple aspects of the studies including enrollment, patient follow-up, protocol, and budget. ResultsThere were 62 grants active during the study period, and of these 54 (87%) were clinical trials and 8 (13%) were natural history studies. 94% of the grantees reported their studies being affected by the COVID-19 pandemic, and the addition of virtual capabilities was reported by 34 (55%) of grantees. ConclusionsThis study suggested two important lessons learned. First, virtual capabilities, when appropriate, can be an important component of trials because they decrease the travel burden on participants and reduce in-person risks, which should increase patient recruitment and retention. Second, building in flexibility in clinical trials is critical in the post-COVID era and could include increasing the use of multi-site trials, clinical networks, and innovative designs and collaborations to speed up trials without compromising study data.
