USP Guideline on Standards for Articles Legally Marketed Outside the U.S.

Background

The United States Pharmacopeia (USP) approach for Standards for Articles Legally Marketed Outside the U.S. (SALMOUS) allows the creation of documentary standards (monographs) for drug substances and drug products that have been approved in and are legally marketed in countries other than the U.S. and are intended to treat neglected diseases, as listed in the Attachment. Where appropriate, USP will provide physical reference standards to support testing of an article against a SALMOUS monograph.

Requirements

In order for monographs for a drug product and/or its drug substance to be developed under the SALMOUS approach, the Sponsor must:

  • Not have obtained final approval from the Food and Drug Administration (FDA) of the drug product and/or its drug substance in the U.S.
  • Have obtained approval for the drug product and/or its drug substance in a country with a stringent regulatory authority (which shall include those countries listed in Section 802 of the Federal Food, Drug and Cosmetic Act as well as those identified on The Global Fund list found at http://www.theglobalfund.org/pdf/guidelines/List_of_Countries_ICH_PICS.pdf, which includes those countries participating in the Pharmaceutical Inspection Convention and Pharmaceutical Inspection Cooperation Scheme and the International Conference on Harmonisation). This requirement may be met through tentative approval of the drug product by FDA, such as tentative approval granted under the President's Emergency Plan for AIDS Relief.
  • Provide a statement to USP indicating in which country or countries the drug product and/or drug substance has been approved and is legally marketed.
  • Follow USP's Guideline for Submitting Requests for Revision to the USP–NF and label the Request "SALMOUS."
  • Inform USP if an application for approval of the drug product is filed in U.S. or if the approval status of the drug product or drug substance elsewhere changes.

Process

  • SALMOUS monographs will not be published in Pharmacopeial Forum for comment, nor will they appear when final in USP–NF. Instead, a proposed monograph will be published in draft on USP's Web site, and a 90–day comment period will commence. Following the comment period and review and approval by the USP Council of Experts (including incorporation of public comments as deemed appropriate), the final monograph will be posted on USP's Web site. The Nomenclature Expert Committee will not review the title of the monograph at this time (unless the monograph also qualifies as a Pending Standard under USP 's Pending Standards Guideline), but may review the title in the future if a USP, NF or Pending Standard is proposed for the article.
  • When final, a SALMOUS monograph will be considered authorized rather than official text because it has been approved by the USP Council of Experts but is not part of an official compendium (USP or NF) of the U.S.
  • Manufacturers of drug substances or drug products may use the designation "S–USP" on certificates of analysis or on container labels, respectively, to indicate compliance to the documentary standards for their drug products or drug substances.

1. For african trypanosomiasis, DB289 is a future drug in Phase III trials.
2. For artemisinin derivatives, only artemisinin-based combination therapies (ACT) should be considered for treatment of malaria to prevent drug resistance with the exception of rectal artesunate, a monotherapy for pediatric in the treatment of malaria.
3. For the drugs used in the treatment of community-acquired pneumonia in adults, see the guidelines developed by the American Thoracic Society at http://www.thoracic.org
4. Symptomatic treatment should be used unless severe, but should remember that hemolytic-uremic syndrome may follow fluroquinolone use.
