Most Post-Approval Studies ‘On Track’: Stein

Share

CDER Office of New Drugs deputy director Peter Stein says it is important for the public to know that most drug post-approval studies are on track. “When studies are delayed,” he says in an FDA Voice blog post, “FDA works with manufacturers to identify the reasons for the delays and ensures that the studies are completed in a timely way. These post-approval studies are vital to enhancing patient safety and public health. The results from completed studies provide additional information that can lead to safety labeling changes, support expanded use of a drug, or alleviate concerns about a potential drug risk. FDA will continue to work to ensure post-marketing requirements (PMR) and post-marketing commitments (PMC) are conducted as promptly as possible.”

According to Stein, FDA issues each year a report on the status of PMRs and PMCs. He says the most recent report showed that overall, the majority of PMRs and PMCs are progressing toward completion according to the original agreed-upon schedule (85% of PMRs and 77% of PMCs).

In addition, FDA informs Congress on the status of the PMR and PMC backlog. Stein says that the report covering FY 2016 showed that the number of open PMRs and PMCs in the backlog has dropped from 1,636 to 143.

“Many factors influence the timely conduct of a study including low use of a product or changes in the standard of care which can reduce the number of patients that can be studied,” Stein writes. “FDA assesses the justification for any delays and if the justification is appropriate, monitors adherence to a revised timetable. The agency can also take enforcement actions if a post-marketing requirement is not met or, depending on the violation, may give a manufacturer the opportunity to voluntarily take prompt, corrective action.”
