Number of Original NADA Approvals for Minor Species

Drug approval is expensive Drug approval is specific Markets for these
uses are smalle.g., 6 million sheep in the U.S. is a small population of animals
Why do MUMS Drugs Need Help With Drug Approval?
![Page 14: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/14.jpg)
14
Even if legal extra-label use is an option, an approval provides Species specific dosing information Accurate withdrawal times
Extra-label use is not legal for medicated feeds – often the only practical way to treat minor species (aquaculture, game birds…).
Limited enforcement discretion.
Drug Approvals for MUMS are important

What Laws & Policies Exist to Increase Drug Availability
for MUMS?
![Page 18: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/18.jpg)

Food, Drug, & Cosmetic Act amended by: AMDUCA ADUFA MUMS Act
Laws
![Page 19: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/19.jpg)
19
AMDUCA – Animal Drug Use Clarification Act of 1994 – legalized extra-label use.
ADUFA – Animal Drug User Fee Act of 2003 – allows collection of fees to support the drug approval process.
MUMS Act – Minor Use & Minor Species Animal Health Act of 2004 – provides incentive programs & Indexing.
The Laws Spelled Out

Some data extrapolation allowed. Flexibility in meeting requirements. Use of literature. Incentive programs. Liaison to USDA’s minor use animal drug
program – NRSP-7 (National Research Support Project #7).
Indexing as an alternative.

What incentives exist for Approvals?
![Page 22: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/22.jpg)

The index of legally marketed unapproved drugs for minor species.
Only for non-food producing minor species (not minor uses).
Not approved for this use. Based on evaluation by an outside
expert panel acceptable to CVM. No extra-label use. Much faster and less expensive.
Indexing – an alternative

The Index List

What Partnerships Exist to Support Approvals?
![Page 27: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/27.jpg)
27
Since pharmaceutical sponsors may not be motivated to seek these approvals, other stakeholders have tried to help.
An effective way is to lower the cost of the approval through providing needed data to support safety and effectiveness.
Interested parties include: other government agencies, university researchers, & producer groups.
Who else can help and how?
![Page 28: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/28.jpg)
28
An outside group can provide the technical sections for:
Effectiveness Target animal safety Human food safety Environmental safety
The pharmaceutical company must:
Provide the Manufacturing technical section
Provide labeling Draft an FOI Summary Provide AOI File the New Animal Drug
Application (NADA)
Who does what?
![Page 29: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/29.jpg)
29
Investigational New Animal Drug (INAD)
files established. Public research partners submit
protocols & study reports to their files. Pharmaceutical sponsor’s file is
proprietary – not made public – contains manufacturing, labeling, and other information.
How does this work?
![Page 30: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/30.jpg)
30
As each technical section is completed it is posted on the FDA website.
See: http://www.fda.gov/AnimalVeterinary/ DevelopmentApprovalProcess/Minor UseMinorSpecies/ucm279384.htm
Research partners are credited and multiple entities can work on a single project.
Public Master File

31
The Pharmaceutical Company files a New Animal Drug Application (NADA) using its own (already accepted) technical sections by reference and the new technical sections from the PMF - also by reference.
A minimal cost approval for the sponsor.
APPROVAL!!
![Page 32: An Overview of Minor Use & Minor Species Issues in the U.S.A](https://reader035.vdocuments.us/reader035/viewer/2022070500/56816806550346895ddd880e/html5/thumbnails/32.jpg)
32
Minor species and minor uses have many unmet needs for legally available new animal drugs.
These species are important. Many incentives, policies, and
programs exist to assist. Legal status provides important label
information to promote safe and effective use.
