A breakthrough therapy designation can be assigned to a drug if "it is a drug which is intended alone or in

(CBER). CDER receives approximately 100 requests per year for breakthrough designation. Historically, about one third were approved. CBER receives 15–30 requests per year. Sponsors must apply for breakthrough status separately for each indication they intend to label the drug for.

applications, usually prior to end of Phase II meeting.
Incentives
Drugs that have been granted breakthrough status are given priority review. The FDA works with the sponsor of the drug application to expedite the approval process. This expedited process can include rolling reviews, smaller clinical trials, and alternative trial designs.
Issues
Critics have said that the name is misleading and provides companies that obtain a breakthrough designation for a drug candidate with a marketing advantage that may be undeserved.
The FDA acknowledges that the name "breakthrough therapy" may be misleading. It was never meant to imply that these drugs are actually "breakthroughs," and it does not ensure that they will provide clinical benefit, but still critics complain that they are based on preliminary evidence, including changes in surrogate markers such as laboratory measurements, that often don't reflect "meaningful clinical benefit."
The FDA guidance states: "Not all products designated as breakthrough therapies ultimately will be shown to have the substantial improvement over available therapies suggested by the preliminary clinical evidence at the time of designation. If the designation is no longer supported by subsequent data, FDA may rescind the designation."
