`

`INTRODUCTION
`1
`This re-assessment of the proposed proprietary name, Zorvolex is written in response to the
`anticipated approval of this NDA within 90 days from the date of this review. DMEPA found the
`proposed name, Zorvolex, acceptable in OSE Review #2013-343 dated April 26, 2013.
`
`2 METHODS AND DISCUSSION
`For re-assessments of proposed proprietary names, DMEPA searches a standard set of databases and
`information sources (see section 4) to identify names with orthographic and phonetic similarity to the
`proposed name that have been approved since the previous OSE proprietary name review. For this
`review we used the same search criteria described in OSE Review #2013-343. We note that none of
`the proposed product characteristics were altered. However, we evaluated the previously identified
`names of concern considering any lessons learned from recent post-marketing experience, which may
`have altered our previous conclusion regarding the acceptability of the proposed proprietary name.
`The searches of the databases yielded no new names, thought to look or sound similar to Zorvolex and
`represent a potential source of drug name confusion
`Additionally, DMEPA searched the United States Adopted Names (USAN) list to determine if the
`name contains any USAN stems as of the last USAN updates. The Safety Evaluator did not identify
`any USAN stems in the proposed proprietary name, as of September 5, 2013.
`
`3 CONCLUSIONS
`The re-evaluation of the proposed proprietary name, Zorvolex, did not identify any vulnerabilities that
`would result in medication errors with any additional names. Thus, DMEPA has no objection to the
`proprietary name, Zorvolex, for this product at this time.
`DMEPA considers this a final review; however, if approval of the NDA is delayed beyond 90 days
`from the date of this review, then the Division of Analgesia, Anesthesia, and Addiction Products
`should notify DMEPA because the proprietary name must be re-reviewed prior to the new approval
`date.
`If you have further questions or need clarifications, please contact Vaishali Jarral, OSE project
`manager, at 301-796-4248.

`2.
`RESULTS
`The following sections provide the information obtained and considered in the evaluation
`of the proposed proprietary name.
`2.1
`PROMOTIONAL ASSESSMENT
`OPDP determined the proposed name is acceptable from a promotional perspective.
`DMEPA and the Division of Anesthesia, Analgesia, and Addiction Products (DAAAP)
`concurred with the findings of OPDP’s promotional assessment of the proposed name.
`
`
`
`SAFETY ASSESSMENT
`2.2
`The following aspects of the name were considered in the overall safety evaluation.
`
`2.2.1 United States Adopted Names (USAN) SEARCH
`On February 11, 2013 the United States Adopted Name (USAN) stem search, identified
`that a USAN stem is not present in the proposed proprietary name.
`
`2.2.2 Components of the Proposed Proprietary Name
`The Applicant stated the name did not have any intended meaning or derivation. This
`proprietary name is comprised of a single/multiple word(s) that does not contain any
`
`Reference ID: 3300229
`

`
`(b) (4)
`
`

`

`
`
`components (i.e. a modifier, route of administration, dosage form, etc.) that is misleading
`or can contribute to medication error.
`
`2.2.4 FDA Name Simulation Studies
`Eighty Nine (89) practitioners participated in DMEPA’s prescription studies. Thirty Nine
`(39) of the participants interpreted the name correctly as ‘Zorvolex’, with correct
`interpretation occurring in the inpatient and outpatient written studies and voice
`prescription. Misinterpretations occurred with expected orthographically and
`phonetically similar letter strings. None of the misinterpreted names overlap with
`marketed products. See Appendix C for the complete listing of interpretations from the
`verbal and written prescription studies.
`
`2.2.5 Comments from Other Review Disciplines
`In response to the OSE, April 25, 2013 e-mail, the Division of Anesthesia, Analgesia, and
`Addiction Products (DAAAP) did not forward any comments or concerns relating to the
`proposed name at the initial phase of the proprietary name review.
`
`2.2.6 Failure Mode and Effects Analysis of Similar Names
`Appendix B lists possible orthographic and phonetic misinterpretations of the letters
`appearing in the proposed proprietary name, Zorvolex. Table 1 lists the names with
`orthographic, phonetic, or spelling similarity to the proposed proprietary name, Zorvolex,
`identified by the primary reviewer, the Expert Panel Discussion (EPD), and other review
`disciplines. The February 4, 2013, proprietary name submission cover letter refers to an
`external name study conducted by
` that was submitted to the IND 103880 on
`September 23, 2011. This external name study was previously evaluated in DMEPA
`review dated March 16, 2012 (OSE review #2011-3627).

`
`2.2. 7 Communication ofDMEPA ’s Final Decision to Other Disciplines
`
`DIVIEPA communicated our findings to the Division of Analgesia, Anesthesia, and
`Addiction Products (DAAAP) via e-mail on April 25, 2013. At that time we also
`requested additional information or concerns that could inform our review. Per e—mail
`correspondence from the Division of Analgesia, Anesthesia, and Addiction Products
`(DAAAP)) on April 26, 2013, they stated no additional concerns with the proposed
`proprietary name, Zorvolex.
`
`3 CONCLUSIONS
`
`The proposed proprietary name, Zorvolex, is acceptable from both a promotional and
`safety perspective.

`
`APPENDICES
`Appendix A
`FDA’s Proprietary Name Risk Assessment considers the promotional and safety aspects
`of a proposed proprietary name. The promotional review of the proposed name is
`conducted by OPDP. OPDP evaluates proposed proprietary names to determine if they
`are overly fanciful, so as to misleadingly imply unique effectiveness or composition, as
`well as to assess whether they contribute to overstatement of product efficacy,
`minimization of risk, broadening of product indications, or making of unsubstantiated
`superiority claims. OPDP provides their opinion to DMEPA for consideration in the
`overall acceptability of the proposed proprietary name.
`The safety assessment is conducted by DMEPA. DMEPA staff search a standard set of
`databases and information sources to identify names that are similar in pronunciation,
`spelling, and orthographically similar when scripted to the proposed proprietary name.
`Additionally, we consider inclusion of USAN stems or other characteristics that when
`incorporated into a proprietary name may cause or contribute to medication errors (i.e.,
`dosing interval, dosage form/route of administration, medical or product name
`abbreviations, names that include or suggest the composition of the drug product, etc.).
`DMEPA defines a medication error as any preventable event that may cause or lead to
`inappropriate medication use or patient harm while the medication is in the control of the
`health care professional, patient, or consumer. 1
`Following the preliminary screening of the proposed proprietary name, DMEPA gathers
`to discuss their professional opinions on the safety of the proposed proprietary name.
`This meeting is commonly referred to the Center for Drug Evaluation and Research
`(CDER) Expert Panel discussion. DMEPA also considers other aspects of the name that
`may be misleading from a safety perspective. DMEPA staff conducts a prescription
`simulation studies using FDA health care professionals. When provided, DMEPA
`considers external proprietary name studies conducted by or for the Applicant/Sponsor
`and incorporates the findings of these studies into the overall risk assessment.
`The DMEPA primary reviewer assigned to evaluate the proposed proprietary name is
`responsible for considering the collective findings, and provides an overall risk
`assessment of the proposed proprietary name. DMEPA bases the overall risk assessment
`on the findings of a Failure Mode and Effects Analysis (FMEA) of the proprietary name
`and misleading nature of the proposed proprietary name with a focus on the avoidance of
`medication errors.
`DMEPA uses the clinical expertise of its staff to anticipate the conditions of the clinical
`setting where the product is likely to be used based on the characteristics of the proposed
`product. DMEPA considers the product characteristics associated with the proposed
`product throughout the risk assessment because the product characteristics of the

`

`
`
`proposed may provide a context for communication of the drug name and ultimately
`determine the use of the product in the usual clinical practice setting.
`Typical product characteristics considered when identifying drug names that could
`potentially be confused with the proposed proprietary name include, but are not limited
`to; established name of the proposed product, proposed indication of use, dosage form,
`route of administration, strength, unit of measure, dosage units, recommended dose,
`typical quantity or volume, frequency of administration, product packaging, storage
`conditions, patient population, and prescriber population. DMEPA considers how these
`product characteristics may or may not be present in communicating a product name
`throughout the medication use system. Because drug name confusion can occur at any
`point in the medication use process, DMEPA considers the potential for confusion
`throughout the entire U.S. medication use process, including drug procurement,
`prescribing and ordering, dispensing, administration, and monitoring the impact of the
`medication.2
`The DMEPA considers the spelling of the name, pronunciation of the name when spoken, and
`appearance of the name when scripted. DMEPA compares the proposed proprietary name
`with the proprietary and established name of existing and proposed drug products and names
`currently under review at the FDA. DMEPA compares the pronunciation of the proposed
`proprietary name with the pronunciation of other drug names because verbal communication
`of medication names is common in clinical settings. DMEPA examines the phonetic
`similarity using patterns of speech. If provided, DMEPA will consider the Sponsor’s intended
`pronunciation of the proprietary name. However, DMEPA also considers a variety of
`pronunciations that could occur in the English language because the Sponsor has little control
`over how the name will be spoken in clinical practice. The orthographic appearance of the
`proposed name is evaluated using a number of different handwriting samples. DMEPA
`applies expertise gained from root-cause analysis of postmarketing medication errors to
`identify sources of ambiguity within the name that could be introduced when scripting
`(e.g.,“T” may look like “F,” lower case ‘a’ looks like a lower case ‘u,’ etc). Additionally,
`other orthographic attributes that determine the overall appearance of the drug name when
`scripted (see Table 1 below for details).

`Lastly, DMEPA considers the potential for the proposed proprietary name to
`inadvertently function as a source of error for reasons other than name confusion. Post-
`marketing experience has demonstrated that proprietary names (or components of the
`proprietary name) can be a source of error in a variety of ways. Consequently, DMEPA
`considers and evaluates these broader safety implications of the name throughout this
`assessment and the medication error staff provides additional comments related to the

`
`safety of the proposed proprietary name or product based on professional experience with
`medication errors.
`
`1. Database and Information Sources
`DMEPA searches the internet, several standard published drug product reference texts,
`and FDA databases to identify existing and proposed drug names that may sound-alike or
`look-alike to the proposed proprietary name. A standard description of the databases
`used in the searches is provided in the reference section of this review. To complement
`the process, the DMEPA uses a computerized method of identifying phonetic and
`orthographic similarity between medication names. The program, Phonetic and
`Orthographic Computer Analysis (POCA), uses complex algorithms to select a list of
`names from a database that have some similarity (phonetic, orthographic, or both) to the
`trademark being evaluated. Lastly, DMEPA reviews the USAN stem list to determine if
`any USAN stems are present within the proprietary name. The individual findings of
`multiple safety evaluators are pooled and presented to the CDER Expert Panel. DMEPA
`also evaluates if there are characteristics included in the composition that may render the
`name unacceptable from a safety perspective (abbreviation, dosing interval, etc.).
`
`2. Expert Panel Discussion
`DMEPA gathers gather CDER professional opinions on the safety of the proposed
`product and discussed the proposed proprietary name (Expert Panel Discussion). The
`Expert Panel is composed of Division of Medication Errors Prevention (DMEPA) staff
`and representatives from the Division of Drug Marketing, Advertising, and
`Communications (OPDP). We also consider input from other review disciplines (OND,
`ONDQA/OBP). The Expert Panel also discusses potential concerns regarding drug
`marketing and promotion related to the proposed names.
`The primary Safety Evaluator presents the pooled results of the database and information
`searches to the Expert Panel for consideration. Based on the clinical and professional
`experiences of the Expert Panel members, the Panel may recommend additional names,
`additional searches by the primary Safety Evaluator to supplement the pooled results, or
`general advice to consider when reviewing the proposed proprietary name.
`
`3. FDA Prescription Simulation Studies
`Three separate studies are conducted within the Centers of the FDA for the proposed
`proprietary name to determine the degree of confusion of the proposed proprietary name
`with marketed U.S. drug names (proprietary and established) due to similarity in visual
`appearance with handwritten prescriptions or verbal pronunciation of the drug name. The
`studies employ healthcare professionals (pharmacists, physicians, and nurses), and
`attempts to simulate the prescription ordering process. The primary Safety Evaluator
`uses the results to identify orthographic or phonetic vulnerability of the proposed name to
`be misinterpreted by healthcare practitioners.
`In order to evaluate the potential for misinterpretation of the proposed proprietary name
`in handwriting and verbal communication of the name, inpatient medication orders and/or
`outpatient prescriptions are written, each consisting of a combination of marketed and
`unapproved drug products, including the proposed name. These orders are optically
`
`Reference ID: 3300229
`
`

`
`

`

`
`
`scanned and one prescription is delivered to a random sample of participating health
`professionals via e-mail. In addition, a verbal prescription is recorded on voice mail.
`The voice mail messages are then sent to a random sample of the participating health
`professionals for their interpretations and review. After receiving either the written or
`verbal prescription orders, the participants record their interpretations of the orders which
`are recorded electronically.
`
`4. Comments from Other Review Disciplines
`DMEPA requests the Office of New Drugs (OND) and/or Office of Generic Drugs
`(OGD), ONDQA or OBP for their comments or concerns with the proposed proprietary
`name, ask for any clinical issues that may impact the DMEPA review during the initial
`phase of the name review. Additionally, when applicable, at the same time DMEPA
`requests concurrence/non-concurrence with OPDP’s decision on the name. The primary
`Safety Evaluator addresses any comments or concerns in the safety evaluator’s
`assessment.
`
`The OND/OGD Regulatory Division is contacted a second time following our analysis of
`the proposed proprietary name. At this point, DMEPA conveys their decision to accept
`or reject the name. The OND or OGD Regulatory Division is requested to provide any
`further information that might inform DMEPA’s final decision on the proposed name.
`Additionally, other review disciplines opinions such as ONDQA or OBP may be
`considered depending on the proposed proprietary name.
`
`5. Safety Evaluator Risk Assessment of the Proposed Proprietary Name
`The primary Safety Evaluator applies his/her individual expertise gained from evaluating
`medication errors reported to FDA, considers all aspects of the name that may be
`misleading or confusing, conducts a Failure Mode and Effects Analysis, and provides an
`overall decision on acceptability dependent on their risk assessment of name confusion.
`Failure Mode and Effects Analysis (FMEA) is a systematic tool for evaluating a process
`and identifying where and how it might fail.3 When applying FMEA to assess the risk of
`a proposed proprietary name, DMEPA seeks to evaluate the potential for a proposed
`proprietary name to be confused with another drug name because of name confusion and,
`thereby, cause errors to occur in the medication use system. FMEA capitalizes on the
`predictable and preventable nature of medication errors associated with drug name
`confusion. FMEA allows the Agency to identify the potential for medication errors due
`to orthographically or phonetically similar drug names prior to approval, where actions to
`overcome these issues are easier and more effective than remedies available in the post-
`approval phase.
`In order to perform an FMEA of the proposed name, the primary Safety Evaluator must
`analyze the use of the product at all points in the medication use system. Because the
`proposed product is has not been marketed, the primary Safety Evaluator anticipates the
`use of the product in the usual practice settings by considering the clinical and product

`characteristics listed in Section 1.2 of this review. The Safety Evaluator then analyzes
`the proposed proprietary name in the context of the usual practice setting and works to
`identify potential failure modes and the effects associated with the failure modes.
`In the initial stage of the Risk Assessment, the Safety Evaluator compares the proposed
`proprietary name to all of the names gathered from the above searches, Expert Panel
`Discussion, and prescription studies, external studies, and identifies potential failure
`modes by asking:
`“Is the proposed proprietary name convincingly similar to another drug name,
