`RESULTS
`The following sections provide the information obtained and considered in the overall
`evaluation of the proposed proprietary name.
`2.1
`PROMOTIONAL ASSESSMENT
`The Office of Prescription Drug Promotion OPDP determined the proposed name is
`acceptable from a promotional perspective. DMEPA and the Division of Metabolic and
`Endocrinology Products (DMEP) concurred with the findings of OPDP’s promotional
`assessment of the proposed name.
`
`SAFETY ASSESSMENT
`2.2
`The following aspects were considered in the safety evaluation of the name.
`
`2.2.1 United States Adopted Names (USAN) Search
`The November 28, 2012 search of the United States Adopted Name (USAN) stems did
`not identify that a USAN stem is present in the proposed proprietary name.
`
`2.2.2 Components of the Proposed Proprietary Name
`The Applicant indicated in their submission that the proposed name, Juxtapid, does not
`have any derivation or an intended meaning. This proprietary name is comprised of a
`single word that does not contain any components (i.e. a modifier, route of
`administration, dosage form, etc.) that are misleading or can contribute to medication
`error.

`
`
`
`2.2.3 FDA Name Simulation Studies
`
`62 practitioners participated in DMEPA’s prescription studies. The interpretations did
`not overlap with or appear or sound similar to any currently marketed products. 36
`practitioners identified the name as Juxtapid.
`‘J’ was misinterpreted as ‘F’ or ‘T’ in 7
`instances. See Appendix C for the complete listing of interpretations from the verbal and
`written prescription studies.
`
`2.2.4 Comments from Other Review Disciplines
`
`DMEP did not forward any comments or concerns relating to the proposed name at the
`initial phase of the proprietary name review.

`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 Office of Prescription Drug Promotion (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: 3229539
`
`
`11
`
`
`
`
`
`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,
`which may cause practitioners to become confused at any point in the usual
`practice setting? And are there any components of the name that may function
`as a source of error beyond sound/look-alike?”
`An affirmative answer indicates a failure mode and represents a potential for the
`proposed proprietary name to be confused with another proprietary or established drug
`name because of look- or sound-alike similarity or because of some other component of
`the name. If the answer to the question is no, the Safety Evaluator is not convinced that
`the names posses similarity that would cause confusion at any point in the medication use
`system, thus the name is eliminated from further review.
`In the second stage of the Risk Assessment, the primary Safety Evaluator evaluates all
`potential failure modes to determine the likely effect of the drug name confusion, by
`asking:
`“Could the confusion of the drug names conceivably result in medication errors
`in the usual practice setting?”
`The answer to this question is a central component of the Safety Evaluator’s overall risk
`assessment of the proprietary name. If the Safety Evaluator determines through FMEA
`that the name similarity would not ultimately be a source of medication errors in the
`usual practice setting, the primary Safety Evaluator eliminates the name from further
`analysis. However, if the Safety Evaluator determines through FMEA that the name
`similarity could ultimately cause medication errors in the usual practice setting, the
`Safety Evaluator will then recommend the use of an alternate proprietary name.
`Moreover, DMEPA will object to the use of proposed proprietary name when the primary
`Safety Evaluator identifies one or more of the following conditions in the Overall Risk
`Assessment:
`a. OPDP finds the proposed proprietary name misleading from a promotional
`perspective, and the Review Division concurs with OPDP’s findings. The Federal
`Food, Drug, and Cosmetic Act provides that labeling or advertising can misbrand a
`product if misleading representations are made or suggested by statement, word,
`design, device, or any combination thereof, whether through a PROPRIETARY
`name or otherwise [21 U.S.C 321(n); See also 21 U.S.C. 352(a) & (n)].
`b. DMEPA identifies that the proposed proprietary name is misleading because of
`similarity in spelling or pronunciation to another proprietary or established name of a
`different drug or ingredient [CFR 201.10.(C)(5)].

`c. FMEA identifies the potential for confusion between the proposed proprietary name
`and other proprietary or established drug name(s), and demonstrates that medication
`errors are likely to result from the drug name confusion under the conditions of usual
`clinical practice.
`d. The proposed proprietary name contains an USAN (United States Adopted Names)
`stem.
`e. DMEPA identifies a potential source of medication error within the proposed
`proprietary name. For example, the proprietary name may be misleading or,
`inadvertently, introduce ambiguity and confusion that leads to errors. Such errors
`may not necessarily involve confusion between the proposed drug and another drug
`product but involve a naming characteristic that when incorporated into a proprietary
`name, may be confusing, misleading, cause or contribute to medication errors.
