`Attention: Mahlaqa Patel
`
`
`Vice President, Regulatory Affairs and Quality Assurance
`
`
`
`
`
`Dear Ms. Patel:
`
`
`
`
`Please refer to your supplemental new drug application (sNDA) dated and received
`
`June 29, 2022, submitted pursuant to section 505(b)(2) of the Federal Food, Drug, and
`
`
`
`
`Cosmetic Act (FDCA) for Subsys (fentanyl sublingual spray).
`
`
`
`
`
`This “Changes Being Effected” sNDA provides for proposed modifications to the
`
`
`approved Transmucosal Immediate-Release Fentanyl (TIRF) Risk Evaluation and
`
`Mitigation Strategy (REMS).
`
`
`
`We have completed our review of this supplemental application. It is approved effective
`
`
`on the date of this letter.
`
`RISK EVALUATION AND MITIGATION STRATEGY (REMS) REQUIREMENTS
`
`
`
`
`
`
`
`
`
`The Shared System (SS) REMS for TIRF products, of which Subsys is a member, was
`
`originally approved on December 28, 2011, and the most recent REMS modification
`
`
`
`was approved on December 3, 2021. The SS REMS consists of a Medication Guide,
`elements to assure safe use, an implementation system, and a timetable for submission
`
`
`of assessments of the REMS.
`
`
`
`
`Your proposed modifications to the REMS consists of changes to the Pharmacy
`
`Education and Prescriber Education.
`
`Your proposed modified REMS, submitted to Drug Master File (DMF) 027320 on
`
`
`
`June 28, 2022, amended and appended to this letter, is approved.
`
`
`
`This shared system REMS, known as the TIRF REMS, currently includes products
`
`listed on the FDA REMS website1.

`NDA 202788/S-029
`Page 2
`
`
`
`Other products may be added in the future if additional NDAs or ANDAs are approved.
`
`
`The timetable for submission of assessments of the REMS remains the same as that
`
`approved on December 3, 2021.
`
`
` There are no changes to the REMS assessment plan described in our December 3,
`
`
` 2021, letter.
`
`We remind you that in addition to the REMS assessments submitted according to the
`timetable in the approved REMS, you must include an adequate rationale to support a
`
` proposed REMS modification for the addition, modification, or removal of any goal or
`
`
`
` element of the REMS, as described in section 505-1(g)(4) of the FDCA.
`
`We also remind you that you must submit a REMS assessment when you submit a
`supplemental application for a new indication for use, as described in section 505-
`
`
`
`1(g)(2)(A) of the FDCA. This assessment should include:
`
`
`
`
`a) An evaluation of how the benefit-risk profile will or will not change with the new
`
`indication;
`
`
`b) A determination of the implications of a change in the benefit-risk profile for the
`
`current REMS;
`
`
`c) If the new indication for use introduces unexpected risks: A description of those
`
`
`risks and an evaluation of whether those risks can be appropriately managed
`
`with the currently approved REMS.
`
`d) If a REMS assessment was submitted in the 18 months prior to submission of the
`
`
`
`
`supplemental application for a new indication for use: A statement about whether
`
`
`the REMS was meeting its goals at the time of that last assessment and if any
`
`modifications of the REMS have been proposed since that assessment.
`
`e) If a REMS assessment has not been submitted in the 18 months prior to
`submission of the supplemental application for a new indication for use: Provision
`
`
`
`
`
`of as many of the currently listed assessment plan items as is feasible.
`
`If you propose a REMS modification based on a change in the benefit-risk profile
`
`
`or because of the new indication of use, submit an adequate rationale to support
`
`
`
`the modification, including: Provision of the reason(s) why the proposed REMS
`
`modification is necessary, the potential effect on the serious risk(s) for which the
`REMS was required, on patient access to the drug, and/or on the burden on the
`
`health care delivery system; and other appropriate evidence or data to support
`the proposed change. Additionally, include any changes to the assessment plan
`
`necessary to assess the proposed modified REMS. If you are not proposing
`REMS modifications, provide a rationale for why the REMS does not need to be
`
`modified.
