Breakthrough therapy is a United States Food and Drug Administration designation that expedites drug development that was created by Congress under Section 902 of the July 9, 2012 Food and Drug Administration Safety and Innovation Act.[1][2] The FDA acknowledges that the designation is not intended to imply that the drug is actually a "breakthrough".[3] It allows the FDA to grant priority review to drug candidates if preliminary clinical trials indicate that the therapy may offer substantial treatment advantages over existing options for patients with serious or life-threatening diseases.[4][5][6] The FDA has other mechanisms for expediting the review and approval process for promising drugs, including fast track designation, accelerated approval, and priority review.[7]

Requirements
A breakthrough therapy designation can be assigned to a drug if "it as a drug which is intended alone or in combination with one or more other drugs to treat a serious or life threatening disease or condition" and if the preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development."[8]
Requests are reviewed by the Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER). CDER receives approximately 100 requests per year for breakthrough designation. Historically, about one third were approved. CBER receives 15-30 requests per year.[9] Sponsors must apply for breakthrough status separately for each indication they intend to label the drug for.
Breakthrough designation applications are submitted as an amendment to the IND applications before the initiation of clinical trials.[10]
Incentives
Drugs that have been granted breakthrough status are given priority review. The FDA will work with the sponsor of the drug application to expedite the approval process. This can include rolling reviews, smaller clinical trials, and alternative trial designs.[11]
