U.S. Pharmacopeia (USP) is committed to support FDA’s List of Off-Patent, Off-Exclusivity Drug Products without an Approved Generic (OPOE) to expedite greater access for important generic drug therapies and help ensure quality and scientific rigor during drug development and manufacturing. We recognize that the pharmaceutical manufacturing industry, FDA, public health community (patient organizations and healthcare practitioners) and USP all share a collective priority to expand patient access to safe, quality medicines. Through initial discussions with these key stakeholders, USP has prioritized FDA’s OPOE list, and launched a Call for Collaboration to advance our shared priorities.
As an organization committed to patient access to quality medicines, we invite you to participate in the Call for Collaboration. The Call for Collaboration bridges the voice of the patient with the scientific and technical capabilities of FDA, USP and pharmaceutical manufacturers.
Successful implementation includes:
- Active engagement and communication with the patient community and their advocates who identify gaps in access to critical therapies
- Regular dialogue with USP’s scientific staff
- Support for the pharmaceutical manufacturers efforts to develop new generic medicines from the OPOE list
USP has monitored the OPOE list to identify opportunities where public quality standards can help increase access to high impact public health medicines. We mapped our monograph development work, prioritized and identified areas where compendial standards can help increase access to quality medicines. We are engaging with stakeholders to help us prioritize more than 450 drugs on the OPOE list. Join the collaboration to advance shared priorities and explore how our monograph development efforts can facilitate greater patient access to quality medicines.
Since 2017, USP has developed 19 monographs associated with 18 drug products on the OPOE list that are in the United States Pharmacopeia-National Formulary (USP-NF). The following 17 monographs are currently official.
