`
`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
`October 17, 2022, submitted pursuant to section 505(b)(2) of the Federal Food, Drug,
`and Cosmetic Act (FDCA) for Subsys (fentanyl sublingual spray).
`
`This Prior Approval sNDA provides for a proposed modification to the approved
`Transmucosal Immediate-Release Fentanyl (TIRF) Risk Evaluation and Mitigation
`Strategy (REMS).
`
`We have completed our review of this 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 August 17, 2022. 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 modification to the REMS consists of changing the timetable for
`submission of assessments in the REMS document from December 23, 2022 to April
`28, 2023 and annually thereafter.
`
`Your proposed modified REMS, submitted to Drug Master File (DMF) 027320 on
`October 14, 2022, 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.

`
`
` Other products may be added in the future if additional NDAs or ANDAs are approved.
`
`There are no changes to the REMS assessment plan described in our December 23,
`2020, 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.
`
`f)
`
`
`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.

`
`If the assessment instruments and methodology for your REMS assessments are not
`included in the REMS supporting document, or if you propose changes to the submitted
`assessment instruments or methodology, you should update the REMS supporting
`document to include specific assessment instrument and methodology information at
`least 90 days before the assessments will be conducted. Updates to the REMS
`supporting document may be included in a new document that references previous
`REMS supporting document submission(s) for unchanged portions. Alternatively,
`updates may be made by modifying the complete previous REMS supporting document,
`with all changes marked and highlighted.

`An authorized generic drug under this NDA must have an approved REMS prior to
`marketing. Should you decide to market, sell, or distribute an authorized generic drug
`under this NDA, contact us to discuss what will be required in the authorized generic
`
`drug REMS submission.
`
`We remind you that section 505-1(f)(8) of FDCA prohibits holders of an approved
`covered application with elements to assure safe use from using any element to block
`or delay approval of an application under section 505(b)(2) or (j). A violation of this
`provision in 505-1(f) could result in enforcement action.
