FDA Briefing Document NDA 208-425 Nicotine Mouth Spray Nonprescription Drugs Advisory Committee Meeting September 18, 2019 The committee will discuss data submitted by GlaxoSmithKline to support new drug application (NDA) 208-425, for over-the-counter (OTC) marketing of nicotine mouth spray, 1 mg. The proposed OTC use is to reduce withdrawal symptoms, including nicotine craving, associated with quitting smoking. The applicant proposes to label the product for 18 years and older. The committee will be asked to consider whether data support an acceptable benefit-risk profile for the nonprescription use of nicotine mouth spray, 1 mg by OTC consumers. i FDA Briefing Document NDA 208-425 Nicotine Mouth Spray Disclaimer Statement The attached package contains background information prepared by the Food and Drug Administration (FDA) for the panel members of the advisory committee. The FDA background package often contains assessments and/or conclusions and recommendations written by individual FDA reviewers. Such conclusions and recommendations do not necessarily represent the final position of the individual reviewers, nor do they necessarily represent the final position of the Review Division or Office. We have brought NDA 208-425 to this Advisory Committee in order to gain the Committee’s insights and opinions, and the background package may not include all issues relevant to the final regulatory recommendation and instead is intended to focus on issues identified by the Agency for discussion by the advisory committee. The FDA will not issue a final determination on the issues at hand until input from the advisory committee process has been considered and all reviews have been finalized. The final determination may be affected by issues not discussed at the advisory committee meeting. ii FDA Briefing Document NDA 208-425 Nicotine Mouth Spray Table of Contents Table of Tables ....................................................................................................................v Table of Figures ................................................................................................................ vii Division Director Memorandum ..........................................................................................8 Draft Topics for Discussion ...............................................................................................12 1.
