Compared Drugs

Introduction of REMS

In September 2007, the United States issued the Food and Drug Administration Amendments Act (FDAAA), which added a new risk reduction plan, the Risk Evaluation and Mitigation Strategy (REMS). REMS refers to the use of a series of off-label measures to ensure that the benefits of high-risk products outweigh the risks. Inappropriate use of these products can result in highly infectious, severe allergic reactions, liver and kidney injury, or reproductive toxicity. The purpose of REMS is to ensure that patients continue to have access to drugs that are relatively safe and clinically irreplaceable, with effective monitoring of known or potential risks.

FDA has the authority to require a marketing authorization holder to submit a REMS evaluation report at the time of registration of a new drug, if necessary. FDA also has the authority to require a drug marketing authorization holder to submit a REMS for a drug that has already been approved for marketing if there is new information about the safety of the drug.

Generic Drugs and REMS

The basis for approval of a generic drug is the demonstration through bioequivalence studies that there is no significant difference in the rate and extent of absorption between the generic drug and the reference listed drugs (RLD).

For REMS-regulated products, distributors are prohibited from selling to individuals or companies without permission. In this case, unless the generic manufacturer can purchase the product directly from the originator, there is no legal way to obtain RLDs to carry out subsequent R&D activities.
