We believe clinical trials for rare disease treatments must account for the unique circumstances of developing a treatment for small patient population sizes. We are focused on advancing consensus around the modernization of clinical trials for rare disease treatments while maintaining support for expedited programs, including Accelerated Approval, Priority Review Voucher, Fast Track, Breakthrough Designation, and Regenerative Medicine Advanced Therapy Designation. In addition, we believe that research incentives established by the Orphan Drug Act (ODA), such as the Orphan Drug Tax Credit, must be preserved to continue to attract and maintain long-term investment in the development of advanced treatments and diagnostics for rare diseases.

Featured Policy Positions

Orphan Drug Tax Credit

The Orphan Drug Tax Credit (ODTC) is a vital lifeline for rare disease patients and must be protected to preserve hope for the rare disease community. Given that about 95% of rare diseases lack any FDA-approved treatment, proposals to reduce the ODTC would have a devastating impact on orphan drug development in the U.S.. To foster hope for millions of Americans living with rare disease, we must continue to support policies and incentives like the ODTC and preserve the gains that have been made since the passage of the ODA.

Research & Development

Research and development (R&D) is at the heart of rare disease innovation. Due to the complex nature of rare diseases, a comparatively higher percentage of operating expenses is dedicated to R&D. Considering that over 95% of rare diseases are without an FDA-approved treatment, policymakers should be compelled to protect incentives for R&D to ensure that companies can continue to innovate and advance ambitious research and development programs that  bring treatments to patients.

Priority Review Voucher

FDA’s priority review vouchers (PRV) provide a critical and cost-effective incentive to spur investment in high-risk development. By building upon this model and making PRVs permanent for use in rare disease, Congress can further offset the high cost and risk of rare disease drug development
