# SUPPLEMENTARY INFORMATION:

## I. Background

                    FDA is announcing the availability of a draft guidance for industry entitled “Oral Drug Products Administered Via Enteral Feeding Tube: In Vitro Testing and Labeling Recommendations.” This draft guidance provides recommendations regarding in vitro testing of oral drug products, other than solutions, administered via enteral feeding tube (hereinafter                     *enteral tube*) that are subject to: (1) New drug applications (original or supplemental) where applicants are seeking and/or revising enteral tube administration instructions and related information in labeling; (2) abbreviated new drug applications where the reference listed drug contains enteral tube administration instructions and related information in labeling; and (3) investigational new drug applications where the investigational drug product is administered or planned for administration via enteral tube. Specifically, the draft guidance provides recommendations for consistent in vitro testing of oral drug products to demonstrate their suitability to be administered via enteral tube. In addition, it supports the development of clear, product-specific enteral tube administration instructions in labeling for administration to patients unable to ingest oral drug products.                

Enteral tubes are critical for patients who are unable to swallow oral dosage forms because of feeding disorders, severe intellectual disabilities, neurological disorders, cancers, and other medical conditions or therapies that compromise swallowing or the function of the proximal gastrointestinal system. It is critical that each drug administered via enteral tube is delivered at the correct dose in a manner that preserves the drug's expected safety and efficacy profile and does not compromise the integrity of the tube.

Some FDA-approved drug products marketed in the United States include instructions for enteral tube administration in their labeling. However, testing is not sufficiently widespread or consistent, and the content and format of labeling statements regarding administration of drug products via enteral tube vary.

The Agency recognizes the need for consistent in vitro testing to ensure safe and effective delivery of drugs that may be administered via enteral tube and to identify drugs that cannot be administered through an enteral tube without altering the safety and effectiveness profile of the drug product or compromising the integrity of the tube.

The draft guidance covers selection of appropriate enteral tubes for testing, selection of the dispersion media and preparation of the drug dispersion, and testing conditions and methods. Additional recommendations are given for modified release drug products. Completion of the recommended testing of a drug product prepared in the same manner as it will be prepared for administration to a patient in the clinical setting should allow applicants to demonstrate whether a drug product is suitable for enteral tube administration and identify drug products that are incompatible with enteral tube administration.

Finally, the draft guidance covers how to summarize information regarding administration of the drug product via enteral tube in labeling, including example labeling statements for drug products that can be safely and effectively administered via enteral tube and labeling statements for drug products that are not recommended for administration via enteral tube.

FDA requests comment from the public regarding the extent to which the recommendations in the guidance could be applicable to nonprescription products marketed under over-the-counter monographs that could be administered via enteral tube.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Oral Drug Products Administered Via Enteral Feeding Tube: In Vitro Testing and Labeling Recommendations.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

## II. Paperwork Reduction Act of 1995

While this draft guidance contains no collection of information, it does refer to previously approved FDA collections of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3521) is not required for this draft guidance. The previously approved collections of information are subject to review by OMB under the PRA. The collections of information in 21 CFR parts 312 and 314 have been approved under OMB control numbers 0910-0014 and 0910-0001, respectively. The collections of information in 21 CFR 201.56 and 201.57 have been approved under OMB control number 0910-0572.
