`INFORMATION PROVIDED VIA RELIANCE
`(LISTED DRUG OR LITERATURE)
`
`2) List the information essential to the approval of the proposed drug that is provided by reliance
`on our previous finding of safety and efficacy for a listed drug by reliance on published
`literature, or by reliance on a final OTC monograph. (If not clearly identified by the
`applicant, this information can usually be derived from annotated labeling.)
`
`Source of information* (e.g.,
`published literature, name of listed
`drug(s), OTC final drug
`monograph)
`Xenazine (tetrabenazine) tablets,
`12.5 mg and 25 mg (NDA 21894)
`
`Information relied-upon (e.g., specific
`sections of the application or labeling)
`
`Clinical studies information.
`Clinical Pharmacology information.
`Non-Clinical Toxicology information.
`Post-marketing data
`
`3) The bridge in a 505(b)(2) application is information to demonstrate sufficient similarity
`between the proposed product and the listed drug(s) or to justify reliance on information
`described in published literature for approval of the 505(b)(2) product. Describe in detail how
`the applicant bridged the proposed product to the listed drug(s) and/or published literature1.
`See also Guidance for Industry Providing Clinical Evidence of Effectiveness for Human Drug
`and Biological Products.
`
`The sponsor’s reliance on FDA’s finding of safety and effectiveness for Xenazine is for nonclinical
`chronic toxicity, carcinogenicity, and reproductive toxicology information, and some clinical
`pharmacology information referenced in the Xenazine label such as additional in vitro drug-drug
`interactions. The Sponsor was unable to obtain the listed drug, Xenazine, to complete BA/BE
`studies that directly compared SD-809 to Xenazine. The Sponsor’s bridging strategy compared
`human PK data from patients enrolled in clinical study SD-809-C-16. Patients entered the study
`taking a stable dose of Xenazine. PK samples were drawn at baseline while they were on a
`stable dose of Xenazine on the day before switching to SD-809, and a second set of PK samples
`were drawn after switching patients to an equivalent, stable dose of SD-809 expected to be
`similar to their prior Xenazine dose. The Cmax of the active α-HTBZ and β-HTBZ metabolites
`from SD-809 were below the Cmax of the active metabolites from Xenazine. Additionally in this
`study, efficacy was evaluated using the Unified Huntington Disease Rating Scale (UHDRS) Total
`Maximal Chorea (TMC) score. Patients who switched overnight from Xenazine to SD-809
`experienced no loss in control of chorea compared to Xenazine, as assessed by the mean UHDRS
`TMC score, through Week 1.
`
`The SD-809 NDA included additional clinical pharmacology information typically required for a
`505(b)(1) NDA including a Mass Balance Recovery Study in healthy volunteers, in vitro and in
`vivo Drug-Drug interaction studies of SD-809 and several of its’ metabolites.
`
`RELIANCE ON PUBLISHED LITERATURE
`
`1For 505(b)(2) applications that rely on a listed drug(s), bridging studies are often BA/BE studies comparing the proposed product to the listed drug(s) Other examples include: comparative
`physicochemical tests and bioassay; preclinical data (which may include bridging toxicology studies); pharmacokinetic/pharmacodynamic (PK/PD) data; and clinical data (which may
`include immunogenicity studies) A bridge may also be a scientific rationale that there is an adequate basis for reliance upon FDA’s finding of safety and effectiveness of the listed drug(s)
`For 505(b)(2) applications that rely upon literature, the bridge is an explanation of how the literature is scientifically sound and relevant to the approval of the proposed 505(b)(2) product

`Proposed product is a different active ingredient and potency.
`
`The purpose ofthefollowing two questions is to determine Ifthere is an approved drugproduct
`that is equivalent or very similar to the product proposedfor approval that should be referenced
`as a listed drug in the pending application.
`
`The assessment ofpharmaceutical equivalencefor a recombinant or biologically—derived product

`application that is already approved (via an NDA or ANDA)?
`
`(Pharmaceutical equivalents are drug products in identical dosageforms intendedfor the
`same route ofadministration that: (1) contain identical amounts ofthe identical active drug
`ingredient, i.e., the same salt or ester ofthe same therapeutic moiety, or, in the case of
`modified release dosageforms that require a reservoir or average or such forms as prefilled
`syringes where residual volume may vary, that deliver identical amounts ofthe active drug
`ingredient over the identical dosing period; (2) do not necessarily contain the same inactive
`ingredients; m (3) meet the identical compendial or other applicable standard ofidentity,
`strength, quality, andpurity, including potency and, where applicable, content uniformity,
`disintegration times, and/or dissolution rates. (21 CFR 320.1 (c), FDA ’s "Approved Drug

`
`PURPOSE OF MEMO
`1
`The Division of Neurology Products requested that we review the container labels for Austedo
`(deutetrabenazine) tablets (Appendix A) to determine if it is acceptable from a medication error
`perspective. The request is in response to the division’s decision, since the completion of our
`previous label and labeling reviewa, to require a Medication Guide (MG).
`2
` ASSESSMENT
`On March 24, 2017, the division informed DMEPA that Austedo (deutetrabenazine) would be
`dispensed with a MG. We reviewed the container labels submitted on March 22, 2017 and
`note the container labels lack the medication guide statement required by 21 CFR 208.24(d).
`3
`CONCLUSION / RECOMMENDATIONS
`The revised container labels are unacceptable from a medication error perspective. The
`product will be dispensed with a Medication Guide (MG); therefore, each container or package
`shall instruct the authorized dispenser to provide a MG to each patient and shall state how that
`MG is provided. We provide recommendations for Teva in Section 3.1.

`
`BACKGROUND
`
`The Sponsor is developing Austedo (SD-809SD-809, deutetrabenazine; d6-tetrabenazine) as a
`treatment for chorea associated with HD, a neurodegenerative genetic autosomal dominant
`neuropsychiatfic disorder characterized by progressive decline of motor and cognitive flmctions.
`Austedo is a vesicular monoamine transporter 2 (VMAT2) inhibitor which is structurally related
`to tetrabenazine.

`CSS Consult: AustedoTM (deutetrabenazine) NDA 208082
`
`This memorandum responds to a consult request from the Division of Neurology Products
`(DNP) to reply to the Sponsor’s request for clarification (Dec 20, 2016, sequence 0030) of CSS’s
`recommendations in DNP’s CR letter (May 27, 2016) to evaluate dependence, withdrawal and
`rebound, after abrupt discontinuation of deutetrabenazine.
`
`The Sponsor received a CR letter on May 27, 2016, after submission of a 505(b) (2) New Drug
`Application for Austedo (deutetrabenazine, SD-809), with Xenazine (NDA 021894,
`tetrabenazine) as the reference listed drug. In that letter CSS requested the Sponsor evaluate
`dependence, withdrawal and rebound at the conclusion of Study ARC-HD (SD-809-C-16). This
`request was a result of sparse clinical withdrawal data along with evidence of possible rebound
`in the first week follow-up after Study SD-809-C-15 First HD ended.
`
`During a Type A meeting (Sep 20, 2016) the Sponsor had the following question for CSS:
`
`Clarification Question for CSS:
`
`Specifically, the team (at TEVA) would like further information on the statement highlighted
`in yellow below. We have investigated several of the scales listed in the CRL in First-HD and
`have not identified a rebound effect unique to SD-809. Any additional information that the
`review team could provide regarding the data assessed as suggesting a rebound effect would be
`of great assistance in assuring we can assess any effects correctly.
`
`In the Meeting Minutes (dated October 18, 2016, Sequence 0029) CSS provided the following
`response:
`
`The change in rating scales scores following withdrawal of study medication in study
`#SD-809-C-15 (First-HD) seems to indicate a possibility of the rebound, which was not
`captured in its entirety because the follow-up period after discontinuing study drug only
`lasted 1 week. It seems patients experienced rapid worsening of TMS, BARS, BBT and
`UPDRS dysarthria/speech question scores during the first week after drug discontinuation.
`This could indicate rebound and CSS recommended an extension of the follow-up period to
`clarify if the observed change in scores after discontinuation was indeed a rebound.
`
`In response, the Sponsor provided their analyses of scales TMS, BARS, BBT and UPDRS
`dysarthria/speech demonstrating, in their opinion, there was no rebound during the one follow-up
`week. Additionally they proposed the following question to CSS:
`
`Question: Does FDA agree with Teva’s definition of rebound and the resulting conclusions
`from the analysis from Study SD-809-C-15? If not, please provide further information on
`how FDA would define rebound in this data set.

`
`Any further information FDA can provide regarding how to best define and therefore assess a
`possible rebound effect would be of great assistance. Teva would also be happy to schedule a
`brief teleconference to discuss this issue with FDA.
`
`CSS RESPONSE
`
`We understand and essentially agree with your definition of rebound and the resulting
`conclusions from the analysis from Study SD-809-C-15. Although there was re-emergence of
`many movements associated with HD, there were no other signs or symptoms reported which
`were associated with a withdrawal syndrome suggesting physical dependence. Thus, it appears
`deutetrabenazine does not produce physical dependence.

`PURPOSE OF MEMO
`1
`This memo presents our evaluation of the revised container labels for Austedo
`(deutetrabenazine) tablets (NDA 208082) to determine if the revised container labels are
`acceptable from a medication error perspective (See Appendix A for images of the revised
`container labels). The revisions are in response to recommendations made by the Office of
`Pharmaceutical Quality (OPQ) on February 28, 2017 and DMEPA during a previous label and
`labeling reviewa OPQ requested Teva add the statement “protect from light and moisture” to
`the side panel of the container labels. DMEPA requested Teva to identify the format they
`intend to use to express the expiration date. To help minimize confusion, we recommended
`that Teva use a format similar to one of the following: MMMYYYY (for example, JAN2017) or
`MMMDDYYYY (for example, JAN012019). In an email dated March 20, 2017, Teva clarified their
`intention to use MM/YYYY as the expiration date format.
