`
`
`
`
`Dear Ms. Kirzecky:
`
`
`
`
`
`
`Please refer to your Supplemental New Drug Application (sNDA) dated November 20, 2012,
`
`
`received November 20, 2012, submitted under section 505(b) of the Federal Food, Drug, and
`
`
`Cosmetic Act (FDCA) for Tygacil (tigecycline).
`
`
`
`
`This “Changes Being Effected” supplemental new drug application proposes to clarify the term
`
`
`“room temperature” to indicate a maximum storage temperature of 25° C/77° F for Tygacil once
`
`reconstituted.
`
`
`
`
`
`We have completed our review of this supplemental application. It is approved, effective on the
`
`
`date of this letter, for use as recommended in the enclosed, agreed-upon labeling text.
`
`
`
`
`We note that your November 20, 2012, submission includes final printed labeling (FPL) for your
`
`
`
`
`package insert. We have not reviewed this FPL. You are responsible for assuring that the
`
`
`wording in this printed labeling is identical to that of the approved content of labeling in the
`
`structured product labeling (SPL) format.
`
`
`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
`
`http://www.fda.gov/ForIndustry/DataStandards/StructuredProductLabeling/default.htm. Content
`
`
`of labeling must be identical to the enclosed labeling text for package insert, 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

`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).

`We remind you that you must comply with reporting requirements for an approved NDA
`
