Challenges in international investigator-led rare disease clinical trials and the case for optimism in inclusion body myositis
Abstract
Objective
This paper aims to provide insight into the challenges and opportunities of conducting an investigator-led, international, multicentre clinical trial for Inclusion Body Myositis (IBM), a rare inflammatory myopathy.
Methods An international, multicentre, randomised, controlled trial of a repurposed drug (sirolimus) was initiated based on promising results from a mono-centric pilot study. The progress of the trial was analysed to identify key challenges encountered and solutions developed. Results This large, collaborative study has presented a mosaic of challenges and opportunities, many ubiquitous with investigator-led trials. Key challenges have included securing adequate funding, coordinating manufacture of placebo, negotiating international contracts, managing limited study budgets and delays linked to the COVID-19 pandemic. Alongside these challenges, the study team have found opportunities for creative and effective solutions, including the flexibility of building study databases, optimising digital data capture and harnessing patient involvement. Conclusion Instrumental to the progress of the trial has been the collaboration between site teams, patient partnership and adaptability.
