Purpose
Fast track is one of five FDA approaches to make new drugs available as rapidly as possible: the others are priority review, breakthrough therapy, accelerated approval and regenerative medicine advanced therapy. Fast track was introduced by the FDA Modernization Act of 1997.Requirements
Fast track designation is designed to aid in the development and expedite the review of drugs which show promise in treating a serious or life-threatening disease and address an unmet medical need. Serious condition: determining whether a disease is serious is a matter of judgment, but generally is based on whether the drug will affect such factors as survival, day-to-day functioning, or the likelihood that the disease, if left untreated, will progress from a less severe condition to a more serious one. Unmet medical need: for a drug to address an unmet medical need, the drug may be developed as a treatment or preventative measure for a disease that does not have a current therapy. The type of information necessary to demonstrate unmet medical need varies with the stage of drug development: early in development, nonclinical data, mechanistic rationale, or pharmacologic data will suffice; later in development, clinical data should be utilized. If there are existing therapies, a fast track eligible drug must show some advantage over available treatment, such as: * Showing superior effectiveness * Avoiding serious side effects of an available treatment * Improving the diagnosis of a serious disease where early diagnosis results in an improved outcome * Decreasing a clinically significant toxicity of an available treatment * Addressing an expected public health need.Incentives
A drug that receives a fast track designation is eligible for some or all of the following: * More frequent meetings with FDA to discuss the drug's development plan and ensure collection of appropriate data needed to support drug approval * More frequent written correspondence from FDA about such things as the design of the proposed clinical trials * Accelerated approval or priority review if the requisite criteria are met. Accelerated approval is meant for drugs that demonstrate an effect on a surrogate, or intermediate endpoint reasonably likely to predict clinical benefit. Priority review shortens the FDA review process for a new drug from ten months to six months, and is appropriate for drugs that demonstrate significant improvements in both safety and effectiveness of an existing therapy. A fast track application is automatically considered for both of these designations. * Rolling review, which means that a drug company can submit completed sections of itsSee also
