`
`We have completed our review of these supplemental applications, and our review of labeling
`revisions for all aforementioned NDAs, as amended, as follows: adding information regarding the
`North American Antiepilepsy Drug Pregnancy Registry and strengthening language related to the risk
`for neural tube defects and other congenital malformations following in utero exposure to
`valproate (and cautioning against the treatment of women of childbearing potential as well as
`pregnant women with valproate due to these risks). These supplemental applications are
`approved, effective on the date of this letter, for use as recommended in the enclosed, agreed-
`upon labeling text.
`
`We are waiving the requirements of 21 CFR 201.57(d)(8) regarding the length of Highlights of
`prescribing information. This waiver applies to all future supplements containing revised
`labeling unless we notify you otherwise.
`
`CONTENT OF LABELING
`
`As soon as possible, but no later than 14 days from the date of this letter, submit the content of
`labeling [21 CFR 314.50(l)] in structured product labeling (SPL) format using the FDA
`automated drug registration and listing system (eLIST), as described at
`

`Page 4
`
`http://www.fda.gov/ForIndustry/DataStandards/StructuredProductLabeling/default.htm. Content
`of labeling must be identical to the enclosed labeling (text for the package insert, Medication
`Guide), with the addition of any labeling changes in pending “Changes Being Effected” (CBE)
`supplements, as well as annual reportable changes not included in the enclosed labeling.
`
`Information on submitting SPL files using eLIST may be found in the guidance for industry
`titled “SPL Standard for Content of Labeling Technical Qs and As” at
`http://www.fda.gov/downloads/DrugsGuidanceComplianceRegulatoryInformation/Guidances/U
`CM072392.pdf.
`
`The SPL will be accessible from publicly available labeling repositories.
`
`Also within 14 days, amend all pending supplemental applications for this NDA, including CBE
`supplements for which FDA has not yet issued an action letter, with the content of labeling
`[21 CFR 314.50(l)(1)(i)] in MS Word format, that includes the changes approved in this
`supplemental application, as well as annual reportable changes and annotate each change. To
`facilitate review of your submission, provide a highlighted or marked-up copy that shows all
`changes, as well as a clean Microsoft Word version. The marked-up copy should provide
`appropriate annotations, including supplement number(s) and annual report date(s).
`
`RISK EVALUATION AND MITIGATION STRATEGY REQUIREMENTS
`
`In our letter dated December 16, 2008, we notified you that a risk evaluation and mitigation
`strategy (REMS) is required for Depakene (valproic acid), Depakote (divalproex sodium), and
`Depacon (valproate sodium) to ensure that the benefits of the drug outweigh the increased risk of
`suicidal thoughts and behavior associated with the class of antiepileptic drugs (AEDs), of which
`Depakene (valproic acid), Depakote (divalproex sodium), and Depacon (valproate sodium) are
`members. We indicated that your REMS must include a Medication Guide and a timetable for
`submission of assessments of the REMS.
`
`We acknowledge receipt of your proposed REMS as described in your January 15, 2009,
`February 6 and 27, 2009, and April 16, 2009 submissions. The proposed REMS, as amended,
`contains a Medication Guide and a timetable for submission of assessments of the REMS.
`
`We have determined that maintaining the Medication Guide as part of the approved labeling is
`adequate to address the serious and significant public health concern and meets the standard in
`21 CFR 208.1. Therefore, it is no longer necessary to include the Medication Guide as an
`element of the REMS to ensure that the benefits of Depakene (valproic acid), Depakote
`(divalproex sodium), and Depacon (valproate sodium) outweigh their risks. Therefore, a REMS
`for Depakene (valproic acid), Depakote (divalproex sodium), and Depacon (valproate sodium) is
`not required. We will notify you if we become aware of new safety information and make a
`determination that a REMS is necessary.
