Regulators of new products confront a tradeoff between speeding a new product to market and collecting additional product quality information. The FDA’s Breakthrough Therapy Designation (BTD) provides an opportunity to understand if a regulator can use new policy to innovate around this tradeoff—i.e., whether it improved regulator productivity by allowing products to come to market more quickly without compromising quality. We find that the BTD program shortened clinical development times by 23 percent and did not impact the ex post safety profile of drugs with the designation. In exploring mechanisms, we find that the BTD program had the greatest impact on less experienced firms and was associated with reduced BTD clinical trial design complexity. The results suggest that targeted regulatory innovation can shorten R&D periods without compromising the quality of new products.

Emerging gene therapy and gene-editing technologies will have a growing impact on patient lives and health-care delivery. We analyzed a decade of data on clinical trials and venture capital investments to understand the likely trajectory of genetically focused therapies in the years ahead. The number of clinical trials and venture capital deals increased substantially from 2006–2017. We observed particularly notable growth in both industry-sponsored trials and trials involving specialty fields of drug development, including oncology, neurology, hematology, ophthalmology, and neurology. As the number of gene-therapy and gene-editing technologies continues to grow, we expect that such therapies will have a significant and heterogeneous impact on health-care delivery, including a shifting of resources from chronic disease management to more intense acute episodic care, an increase in the complexity of required intellectual property and manufacturing know-how, and the potential expansion of biopharmaceutical companies into service-based business models.
