`
`
`Dear Ms. Wu:
`
`Please refer to your supplemental new drug application (sNDA) dated March 29, 2019,
`received March 29, 2019, and your amendments, submitted under section 505(b) of the
`Federal Food, Drug, and Cosmetic Act (FDCA) for IDHIFA (enasidenib) tablets, 50 mg
`and 100 mg.
`
`This Prior Approval supplemental new drug application provides for the following
`revisions to the United States Prescribing Information:
` Updated elimination half-life and Cmax concentrations (Section 12.3),
`
` Updated timeframe for contraceptive use following discontinuation of IDHIFA
`
`
`(Sections 5.2,
`8.3, and 17, and Medication Guide), and
` Updated timeframe in which differentiation syndrome has been observed
`
`(Section 5.1).
`
`
`APPROVAL & LABELING
`
`We have completed our review of this application, as amended. It is approved, effective
`
` on the date of this letter, for use as recommended in the enclosed agreed-upon
`
`labeling.
`
`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
`FDA.gov.1 Content of labeling must be identical to the enclosed labeling (text for the
`Prescribing Information and 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 SPL Standard for Content of Labeling Technical Qs and As.2
`
`
`The SPL will be accessible from publicly available labeling repositories.
`
`Also within 14 days, amend all pending supplemental applications that include labeling
`changes 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 Microsoft Word
`format, that includes the changes approved in this supplemental application, as well as
`annual reportable changes. To facilitate review of your submission(s), 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).
`
`REQUIRED PEDIATRIC ASSESSMENTS
`
`
`Under the Pediatric Research Equity Act (PREA) (21 U.S.C. 355c), all applications for
`new active ingredients (which includes new salts and new fixed combinations), new
`indications, new dosage forms, new dosing regimens, or new routes of administration
`
`are required to contain an assessment of the safety and effectiveness of the product for
`the claimed indication in pediatric patients unless this requirement is waived, deferred,
`or inapplicable.
`
`Because none of these criteria apply to your application, you are exempt from this
`requirement.
`
`REPORTING REQUIREMENTS
`
`
`We remind you that you must comply with reporting requirements for an approved NDA
`(21 CFR 314.80 and 314.81).
`
`If you have any questions, call Jennifer Lee, Senior Regulatory Health Project Manager,
`
`at (240) 402-4622.
