Optimizing regulatory frameworks for gene therapies in rare diseases: Challenges and solutions.

The advent of genetic medicines and advanced diagnostics has revolutionized the treatment landscape for rare diseases and, with over 10,000 identified conditions affecting millions globally, has the potential to improve many lives. Despite this progress, only 5% of rare diseases have FDA-approved therapies, highlighting a significant unmet need. This article examines the critical need for optimizing the regulatory environment to support the development and approval of gene therapies for rare and ultrarare diseases, which often face unique challenges due to their complexity in the midst of a rapidly evolving field. Key issues discussed include the mismatch between traditional regulatory paradigms and the nature of gene therapies, the need for innovative clinical trial designs, and the importance of flexible manufacturing processes. The article proposes targeted reforms to align regulatory frameworks with the needs of patients with rare diseases and the pace of science, emphasizing the value of a holistic evidence approach, platform technologies, and iterative manufacturing evaluations. By addressing these challenges, we can accelerate the development of life-changing therapies in order to realize the opportunity to provide treatments to patients with rare genetic disorders in their lifetime.
