Gene Therapy Platform for Rare Diseases

Genetic Therapies for Rare Diseases

There are approximately 10,000 identified rare diseases, yet only a few hundred have treatments are approved. Gene therapy is particularly relevant to rare disease patients, as more than 80 percent of rare diseases have a known monogenic (single-gene) cause. Traditional small molecule drugs often work by minimizing symptoms rather than curing the disease. When treating a chronic condition, this can mean frequent administration of the drug or drugs required to manage the condition. In contrast, gene therapy has the potential to correct underlying genetic defects, offering a cure rather than simply managing symptoms. Moreover, successful gene therapy may require only a single dose to confer lifelong improvement rather than requiring a lifetime of ongoing treatment.

Developing a Gene Therapy "Toolbox"

Scientists have been researching gene therapies for decades, but the U.S. Food and Drug Administration only recently approved the first gene therapy for patients in 2017. As a new modality of treatment, gene therapy presents unique technical and regulatory challenges. To help accelerate the field of gene therapy, the TRND program has initiated a suite of pilot projects in collaboration with biotechnology and academic groups.

Projects are designed to address specific obstacles in gene therapy development. New technologies to scale up gene-vector manufacturing and to deliver the transgene to the right tissue at the right time and dosage are being developed. TRND’s goals are to develop these technologies and disseminate the best practices to achieve regulatory approval for new gene therapies. By building a toolbox of technologies and information, TRND aims to improve the speed of development and reduce costs for gene therapy in general.
