How FDA fast track designation helps to speed up drug development

fda fast track designation is important for faster review of drugs that qualify

A process is  followed to determine if  a drug merits FDA first track designation. First the sponsor must submit a request for FDA  fast track designation or just fast track to the FDA. The request must include the supporting documents and the  proposed use. The FDA is required by the statutes to accept or reject the request. The advantages of FDA fast track designation include review of parts of the NDA before the complete application is ready, increased communication through allocation of resources, shortened review time.

The fist track designation strategy is based on the FDA Modernization Act of 1997. This strategy allows drugs which met a two main criteria to be designated fast track drugs. Firstly the drug must be for the treatment of a serious or life-threatening condition. Secondly the drug has to address a medical need which has not been addressed before.

If the Fast Track designation is approved by the FDA, the sponsor is encouraged to meet with the agency for discussion about the development plans. These discussions are useful if initiated early before the sponsor submits a NDA/BLA. Early consultations may help to clarify certain elements of the clinical trial designs and the presentations. The consultation meetings are useful as they help to resolve issues that could delay approval of the NDA/BLA.

FDA consultation meetings can be requested by any sponsor who requires FDA inputs during the process of drug development. However there is a unique opportunity within FDA Fast Track designation which allows the sponsor to submit sections of an NDA/BLA as they are completed. This option is not available for sponsors submitting the standard NDA/BLA. These sponsors submit a complete application to the FDA at once.

Of the FDA approved novel drugs in 2015, fourteen drugs (31%) Had FDA fast track designation. These drugs were approved because they had a potential to meet a need that had not been met before.
