Accelerated approval
(1992) FDA regulations changed to permit accelerated approval of drugs for AIDS and cancer; drugs could be approved for marketing prior to completion of Phase III trials provided rigorous follow-up studies were performed (Phase IV trials).
Pros and cons of accelerated approval
Pros: 1) Drugs needed even if their benefits may be marginal, 2) unknown risks with early approval are balanced by the need for more effective drugs.
Cons: 1) Manufacturers often fail to complete Phase IV trials, 2) if Phase IV trials fail to confirm a clinical benefit, there is no clear mechanism for removing the drug from the market.
