Realizing the Potential of Gene Therapies for Rare and Ultra-Rare Inherited Diseases.

Abstract

Rare and ultrarare diseases have been central to the field of gene therapy since its earliest stage, and we are now witnessing more and more effective treatments entering the clinical realm for patients in need. However, despite promising results across a range of rare diseases, transformative gene therapies may not be available and accessible to patients for nonmedical reasons. Traditional regulatory and commercialization pathways to licensed products seem to be prohibitive for ultrasmall patient populations. Here, we highlight some of the challenges of delivering gene therapies in rare diseases and discuss innovative solutions being proposed by the gene therapy community.
