`
`Attention:
`
`Richard Fanelli, PhD
`Head of Regulatory Affairs
`
`
`Dear Dr. Fanelli:
`
`Please refer to the following Supplemental New Drug Applications (sNDAs) dated and received
`March 28, 2018, and June 15, 2018, and your amendments, submitted under section 505(b)of the
`Federal Food, Drug, and Cosmetic Act (FDCA) for OXYCONTIN (oxycodone hydrochloride)
`Extended-Release Tablets.
`
`We also refer to our letter dated September 28, 2017, notifying you that under section 505-1 of
`the FDCA, we have determined that your approved Extended-Release and Long-Acting
`(ER/LA) Opioid Analgesics Risk Evaluation and Mitigation Strategy (REMS) must be modified
`to ensure that training is made available to healthcare providers involved in the treatment and
`monitoring of patients with pain, and to implement the FDA Education Blueprint for Health Care
`Providers Involved in the Treatment and Monitoring of Patients with Pain to ensure the benefits
`of the drugs outweigh the risks of adverse outcomes (addiction, unintentional overdose, and
`death) resulting from inappropriate prescribing, abuse, and misuse.
`
`Finally, we refer to our letter dated June 1, 2018, notifying you, under section 505(o)(4) of the
`FDCA, of new safety information that we believe should be included in the labeling for
`OXYCONTIN. This information pertains to the addition of the REMS program details to product
`labeling for the class of opioid analgesics intended for use in the outpatient setting.
`
`Supplement S-040 provides for the REMS modification required under section 505-1 of the
`FDCA, consistent with our September 28, 2017, letter.
`
`Supplement S-041 provides for revisions to the labeling for OXYCONTIN consistent with our
`June 1, 2018, Safety Labeling Change Notification letter.

`
`

`

`NDA 022272/S-040/S-041
`Page 7
`
`
`
`
`e. Evaluation of prescriber behavior and patient outcomes: The results of an
`evaluation of the effect of REMS-compliant CE on prescriber behavior and
`patient outcomes. This evaluation should include the following:
`
`
`
`
`
`i. Development and use of metrics that assess prescriber behaviors and
`patient outcomes relating to key messages in the FDA Opioid Analgesic
`REMS Education Blueprint for Health Care Providers Involved in the
`Treatment and Monitoring of Patients with Pain (“FDA Blueprint”). The
`assessment should also include an evaluation of potential unintended
`adverse patient outcomes resulting from changes in prescribing practices
`(e.g., withdrawal symptoms or increased pain due to inappropriate rapid
`opioid tapering, patient abandonment, seeking of illicit opioids, suicide
`attempts/completion)
`
`
`ii. Use of an appropriate control group (i.e., providers who have not
`completed REMS-compliant accredited CE), and rigorous control for
`confounding, to allow an assessment of whether any observed changes in
`prescriber behaviors or patient outcomes can be attributed to the CE
`
`4. Knowledge
`
`
`a. Evaluation of CE participants: The results of evaluations to determine the impact
`of REMS-compliant accredited CE on participants’ knowledge, attitudes, and
`self-reported behavior around pain management and appropriate opioid
`prescribing. All evaluations should be representative and generalizable to the
`targeted health care professionals taking the REMS-compliant accredited CE and
`assess understanding of key elements from all sections of the FDA Opioid
`Analgesic REMS Education Blueprint for Health Care Providers Involved in the
`Treatment and Monitoring of Patients with Pain (“FDA Blueprint”). Multiple
`methodologies should be used, including but not limited to the following:
`
`
`i. Pre- and post-activity assessments using validated instruments. These
`assessments could be integrated into live, online, or multimedia formats
`using interactive approaches to enhance the educational value of the
`activity. Different versions or subsets of questions from a standardized
`assessment tool could be employed to cover all key messages and sections
`of the FDA Opioid Analgesic REMS Education Blueprint for Health Care
`Providers Involved in the Treatment and Monitoring of Patients with Pain
`(“FDA Blueprint”), in aggregate, while reducing the time burden for
`individual participants and allowing the assessment to be tailored for
`different types of healthcare professionals.
`
`ii. A long-term follow-up evaluation of participants to assess retention of
`knowledge and skills, application of learning to clinical practice, self-
`reported change in behavior, and barriers to change. Consider
`
`Reference ID: 4321305

`
`
`
`incentivizing participation in follow-up assessment, for example through
`additional CE credits.
`
`b. Evaluation of Patient Understanding: The results of an evaluation of patients’ and
`caregivers’ understanding of the serious risks of opioid analgesics and their
`understanding of how to use these products safely. This evaluation may include,
`for example, surveys of patients from a representative sample of patients taking
`opioid analgesics with respect to education level, insurance status, and geographic
`location.
`
`5. During transition from the ER/LA Opioid Analgesics REMS to Opioid Analgesic REMS,
`data to be included until the last enduring activity has been reported:
`
`
`a. For each CE activity released under the ER/LA Opioid Analgesics REMS that
`remains active, provide the name of the CE Provider, the title of the activity, and
`the date the activity will expire
`
`b. Aggregate data on participants and completers should be collected using original
`MEMS 2.0 definitions
`
`
`
`
`
`6. Methodologies: A timeline for submission of the assessment protocols, including data
`sources and the methodologies used to conduct all the above described analyses. Each
`assessment report should update the dates of submission for each component of the
`assessment.
`
`The first REMS assessment for the Opioid Analgesic REMS, due 6-months from the date of this
`letter, will include only information outlined in items 1, 2a, 2b, and 2c, and any additional
`information the REMS Program Companies (RPC) deems necessary to describe REMS
`implementation.
`
`The requirements for assessments of an approved REMS under section 505-1(g)(3) include with
`respect to each goal included in the strategy, an assessment of the extent to which the approved
`strategy, including each element of the strategy, is meeting the goal or whether 1 or more such
`goals or such elements should be modified.
`
`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;
`
`Reference ID: 4321305
`
`

`

`NDA 022272/S-040/S-041
`Page 9
`
`
`
`
`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. Prominently identify the
`submission containing the assessment instruments and methodology with the following wording
`in bold capital letters at the top of the first page of the submission:
