Notice of availability.

SUMMARY:

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Nonclinical Testing of Orally Inhaled Nicotine-Containing Drug Products.” The document provides guidance regarding the nonclinical information FDA recommends to support development and approval of orally inhaled nicotine-containing drug products, including electronic nicotine delivery systems intended for smoking cessation and other chronic uses.

DATES:

Submit either electronic or written comments on the draft guidance by October 5, 2018 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

ADDRESSES:

You may submit comments on any guidance at any time as follows:

Electronic Submissions

Submit electronic comments in the following way:

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Nonclinical Testing of Orally Inhaled Nicotine-Containing Drug Products.” This document provides guidance on the nonclinical information FDA recommends to support development and approval of orally inhaled nicotine-containing drug products for smoking cessation and other chronic uses.

The recommended nonclinical assessment as outlined in the guidance addresses safety of novel components of the drug product formulation, novel chemicals generated from any component of the drug product formulation by the delivery system, and novel impurities. As used in the guidance, the phrase novel component of the formulation refers to active and inactive ingredients intentionally added to the drug product that have not been approved in drugs at an equal or greater dose, for an equal or greater duration of use, or by a relevant route of administration sufficient to characterize toxicity via local and systemic exposure. FDA expects that in many cases use of the delivery system will generate novel chemicals (e.g., heat-generated products).

Orally inhaled nicotine-containing drug products developed for smoking cessation and other chronic uses are expected to involve continuous use or chronic intermittent use resulting in 6 Start Printed Page 38316months or more exposure over a lifetime. Because of the duration of use, the nonclinical assessment for marketing approval should include general toxicity studies, developmental and reproductive toxicity studies, an assessment of carcinogenic potential, and supporting toxicokinetic and pharmacokinetic studies.

FDA is aware of the serious risk associated with smoking and is committed to facilitating the development of therapies to support smoking cessation efforts. This guidance focuses on novel components of the drug product formulation, heat-generated products, and impurities that are generally not well characterized. Orally inhaled nicotine-containing tobacco products, including electronic nicotine delivery systems currently marketed in the United States, have already been associated with toxicity concerns (Refs 1-4). An adequate nonclinical assessment, as described in this guidance, can address the potential toxicity of chemicals from orally inhaled nicotine-containing drug products. As noted in the guidance, sponsors can use an alternative approach if that approach provides adequate safety information.

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 nonclinical testing of orally inhaled nicotine-containing drug products. 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. This guidance is not subject to Executive Order 12866.

II. Paperwork Reduction Act of 1995

This guidance refers to previously approved collections of information that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR part 312 have been approved under OMB control number 0910-0014. The collections of information resulting from special protocol assessments have been approved under OMB control number 0910-0470.
