Designation of Official Names and Proper Names for Certain 
Biological Products

AGENCY: Food and Drug Administration, HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA) is proposing a 
regulation to designate official names and proper names for certain 
biological products. These products are filgrastim-sndz (Biologics 
License Application (BLA) 125553), filgrastim (BLA 103353), tbo-
filgrastim (BLA 125294), pegfilgrastim (BLA 125031), epoetin alfa (BLA 
103234), and infliximab (BLA 103772). The official names and proper 
names of these products would include distinguishing suffixes composed 
of four lowercase letters and would be designated as filgrastim-bflm 
(BLA 125553), filgrastim-jcwp (BLA 103353), filgrastim-vkzt (BLA 
125294), pegfilgrastim-ljfd (BLA 125031), epoetin alfa-cgkn (BLA 
103234), and infliximab-hjmt (BLA 103772). Although FDA is continuing 
to consider the appropriate naming convention for biological products, 
including how such a convention would be applied retrospectively to 
currently licensed products, FDA is proposing to take action with 
respect to these six products because of the need to encourage routine 
usage of designated suffixes in ordering, prescribing, dispensing, 
recordkeeping, and pharmacovigilance practices for the biological 
products subject to this rulemaking, and to avoid inaccurate 
perceptions of the safety and effectiveness of biological products 
based on their licensure pathway.

DATES: Submit either electronic or written comments on the proposed 
rule by November 12, 2015. See section IV of this document for the 
proposed effective date of any final rule that may publish based on 
this proposal.

I. Background

    With the passage of the Biologics Price Competition and Innovation 
Act of 2009 (BPCI Act), which established an abbreviated licensure 
pathway for products demonstrated to be biosimilar to or 
interchangeable with an FDA-licensed reference product, a growing 
number of biological products will be entering the marketplace.
    Section 351(k) of the Public Health Service Act (the PHS Act) (42 
U.S.C. 262(k)), added by the BPCI Act, sets forth the requirements for 
an application for a proposed biosimilar product and an application or 
a supplement for a proposed interchangeable product. Section 351(i) of 
the PHS Act defines biosimilarity to mean that the biological product 
is highly similar to the reference product notwithstanding minor 
differences in clinically inactive components and that there are no 
clinically meaningful differences between the biological product and 
the reference product in terms of the safety, purity, and potency of 
the product (section 351(i)(2) of the PHS Act). To meet the additional 
standard of interchangeability, an applicant must provide sufficient 
information to demonstrate biosimilarity and also to demonstrate that 
the biological product can be expected to produce the same clinical 
result as the reference product in any given patient and, if the 
biological product is administered more than once to an individual, the 
risk in terms of safety or diminished efficacy of alternating or 
switching between the use of the biological product and the reference 
product is not greater than the risk of using the reference product 
without such alternation or switch (section 351(k)(4) of the PHS Act). 
Interchangeable products may be substituted for the reference product 
by a pharmacist without the intervention of the prescribing health care 
provider (section 351(i)(3) of the PHS Act).
    During FDA's implementation of the BPCI Act, the Agency has opened 
several dockets to solicit comments on issues related to the naming of 
biological products licensed under section 351(k) of the PHS Act.\1\
---------------------------------------------------------------------------

    \1\ See, e.g., notices that published in the Federal Register 
``Approval Pathway for Biosimilar and Interchangeable Biological 
Products; Public Hearing; Request for Comments'' (75 FR 61497, 
October 5, 2010) and ``Draft Guidances Relating to the Development 
of Biosimilar Products; Public Hearing; Request for Comments'' (77 
FR 12853, March 2, 2012) and other public dockets established by 
FDA.
---------------------------------------------------------------------------

    FDA also has received several citizen petitions directed to the 
nonproprietary naming of biosimilar products. The citizen petition 
submitted by Johnson & Johnson requests that FDA require biosimilar 
products to bear nonproprietary names that are similar to, but not the 
same as, those of their reference products or of other biosimilars (see 
Docket No. FDA-2014-P-0077, available at http://www.regulations.gov). 
The citizen petitions submitted by the Generic Pharmaceutical 
Association and Novartis request that FDA require biosimilar products 
to be identified by the same nonproprietary name as their reference 
products (see Docket Nos. FDA-2013-P-1153 and FDA-2013-P-1398, 
respectively, available at http://www.regulations.gov). Novartis 
supplemented its petition to propose a unique name for all biologics 
and biosimilars, such that if a biosimilar sponsor elected not to use a 
unique proprietary name for its product, FDA should assign a unique 
nonproprietary name composed of the reference product nonproprietary 
name supplemented with a distinguishable suffix linked to the 
biosimilar sponsor so that it can be differentiated from the reference 
product. While FDA is proposing to designate distinguishable 
nonproprietary names for the six biological products that are the 
subject of this rulemaking for the reasons discussed in this document, 
FDA is continuing to consider the issues raised by these citizen 
petitions and the comments submitted to the corresponding public 
dockets with respect to establishing a general naming convention for 
biological products.
    In a separate notice published elsewhere in this issue of the 
Federal Register, FDA announced the availability of a draft guidance 
document entitled ``Nonproprietary Naming of Biological Products'' 
(draft guidance). The draft guidance describes FDA's current thinking 
and requests additional public comment on the Agency's proposal to 
implement a naming convention of a proper name that will include a core 
name and a designated suffix for all biological products within the 
scope of the guidance. For originator products, FDA intends to use a 
core name that is the name adopted by the United States Adopted Names 
(USAN) Council for the drug substance when available. If the biological 
product is a related biological product,\2\ a biosimilar product, or an 
interchangeable product, the core name will be the name of the drug 
substance contained in the relevant previously licensed product. As 
described in the draft guidance, a designated suffix composed of four 
lowercase letters will be added to the core name of each product and 
will be attached with a hyphen. Importantly, use of a shared core name 
would indicate a relationship among products. The placement of the 
identifier as a suffix should result in biological products with the 
same core name being grouped together in electronic databases to help 
health care providers identify these products. The draft guidance 
states that FDA intends to apply the naming convention described in the 
guidance to interchangeable products and is considering comment on two 
alternative approaches: A unique suffix that distinguishes an 
interchangeable product from other products sharing the same core name, 
or a suffix shared with the reference product.
---------------------------------------------------------------------------

    \2\ A ``related biological product'' is described in the 
guidance as a biological product submitted in a BLA under section 
351(a) of the PHS Act (i.e., a ``stand-alone'' BLA) for which there 
is a previously licensed biological product submitted in a different 
section 351(a) BLA that contains a drug substance for which certain 
nomenclature conventions (e.g., USAN Guiding Principles) would be 
expected to provide for use of the same drug substance name. An 
``originator biological product'' is defined as a biological product 
submitted in a BLA under section 351(a) of the PHS Act (i.e., a 
``stand-alone'' BLA) for which there is no previously licensed 
biological product submitted under section 351(a) that is a related 
biological product. FDA uses these definitions for purposes of this 
notice.
---------------------------------------------------------------------------

    While the draft guidance describes a naming convention in which the 
designated suffixes would be devoid of meaning, the notice of 
availability for the draft guidance invites comment not only on that 
naming convention but also on the benefits and challenges of alternate 
approaches, including meaningful suffixes such as a suffix derived from 
the name of the license holder.
    The draft guidance describes FDA's rationale for the proposed 
naming convention and requests public comment on FDA's intention to 
apply this convention to biological products previously licensed and 
newly licensed under section 351(a) or section 351(k) of the PHS Act. 
The draft guidance explains that FDA is continuing to consider the most 
effective regulatory approach to implement the naming convention for 
previously licensed biological products, and FDA encourages interested 
parties to submit comments on biological product naming issues to the 
public docket established for the draft guidance (Docket No. FDA-2013-
D-1543, available at http://www.regulations.gov).
    For the reasons described in the following section, FDA believes it 
is necessary at this time to designate official names and proper names 
for the

[[Page 52226]]

six biological products described in this proposed rule.

II. Description of the Proposed Rule

    This proposed rule would designate the official names and the 
proper names of six biological products that fall under one of the 
following categories: (1) A reference product for an approved or 
publicly disclosed section 351(k) application (i.e., filgrastim (BLA 
103353), pegfilgrastim (BLA 125031), infliximab (BLA 103772), and 
epoetin alfa (BLA 103234)); (2) a related biological product to one of 
these reference products (i.e., tbo-filgrastim (BLA 125294)); or (3) a 
biosimilar product (i.e., filgrastim-sndz (BLA 125553)).\3\
---------------------------------------------------------------------------

    \3\ FDA recognizes that a limited number of previously licensed 
biological products share the same proper name. As described in the 
draft guidance, FDA intends to apply the naming convention to 
biological products previously licensed under section 351(a) of the 
PHS Act, and is continuing to consider the most effective regulatory 
approach. In the meantime, FDA is proposing to assign distinguishing 
identifiers to biological products that are referenced by approved 
or publicly disclosed section 351(k) applications and any related 
biological products to those reference products.
---------------------------------------------------------------------------

    Section 508 of the Federal Food, Drug, and Cosmetic Act (the FD&C 
Act) (21 U.S.C. 358), which applies to biological products pursuant to 
section 351(j) of the PHS Act, provides FDA with authority to designate 
official names for drugs if it determines that such action is necessary 
or desirable in the interest of usefulness and simplicity. Section 508 
further specifies that any official name designated under that section 
shall be the only official name of that drug used in any official 
compendium published after such name has been prescribed or for any 
other purpose of this chapter. Under Sec.  299.4(e) (21 CFR 299.4(e)), 
FDA will publish official names under the provisions of section 508 of 
the FD&C Act when the Agency determines, among other bases, that the 
USAN or other official or common or usual name is unduly complex or is 
not useful for any other reason.
    For biological products licensed under the PHS Act, FDA designates 
the proper name in the license for use upon each package of the 
biological product (see section 351(a)(1)(B)(i) of the PHS Act and 21 
CFR 600.3(k)). The proper name of a biological product reflects certain 
scientific characteristics of the product, such as chemical structure 
and pharmacological properties. Among other things, the proper name of 
a biological product helps health care providers identify the product's 
drug substance and distinguish biological products from one another. 
Although FDA typically designates the proper name of a product upon its 
licensure, FDA also has the authority to designate proper names for 
biological products through regulation (see, e.g., designation of 
proper names for various products in 21 CFR part 640).

A. Basis for the Designation of Distinguishable Names for Certain 
Biological Products

1. Safe Use
    Biological products generally consist of large, complex molecules 
and can raise unique safety concerns related to immunogenicity. FDA 
believes that the nonproprietary naming convention for the biological 
products described in this proposed rule should help prevent 
inadvertent substitution, which may lead to unintended switching or 
alternating of biological products that have not been determined by FDA 
to be interchangeable with each other. FDA believes this naming 
convention will help to facilitate safe use and protect the safety of 
patients.
    Inadvertent switching between biological products that have not 
been shown to be interchangeable may affect immune response. For 
example, in some instances, immune responses to therapeutic proteins 
may pose safety and efficacy issues (Ref. 1). For example, immune 
responses can lead to significant clinical consequences, such as pure 
red cell aplasia; inhibition of the efficacy of therapeutics; and 
reactions, including serum sickness and anaphylaxis (Ref. 1). 
Individual patients can vary in their immune responses to protein 
products, and these differences can be caused by the same genetic 
components that have an impact on sensitivity to small changes in 
structure (Ref. 2). Thus, switching or alternating of biological 
products not determined by FDA to be interchangeable may raise unique 
safety concerns related to immunogenicity.
    If originator biological products, related biological products, and 
biosimilar products share the same proper name, a patient could receive 
a product different from what was intended to be prescribed, leading to 
medication errors. For example, this could occur if a biosimilar 
product were licensed for fewer than all of the indications and routes 
of administration for which its reference product is licensed, or is 
packaged in a different delivery system (e.g., a pre-filled syringe 
instead of a vial) than approved for its reference product, which may 
lead to confusion and dosing errors. A related biological product also 
may be licensed for different indications than an originator biological 
product and may have different dosage forms or strengths than an 
originator biological product. Confusion may also arise among health 
care providers who, based on their experience with small-molecule drugs 
and generic versions of those drugs, may incorrectly assume the use of 
the same proper name to mean that the biological products are 
interchangeable.
    Thus, FDA has determined that designation of a proper name 
containing a distinguishing identifier for these six biological 
products is the best mechanism to facilitate their safe use. FDA 
believes that incorporating a distinguishing suffix into the 
nonproprietary names of these six biological products will increase the 
likelihood that the intended biological product will be prescribed and 
will not be inadvertently substituted at the dispensing or product 
administration level. Specifically, FDA believes that incorporation of 
these suffixes into the nonproprietary product names listed in 
prescribing, ordering, and dispensing systems will assist prescribers 
in selecting the specific intended product, pharmacists in dispensing 
the correct product, and health care providers in administering the 
correct product.
    Health care providers and information technology specialists who 
program electronic databases can consult the Purple Book (Lists of 
Licensed Biological Products with Reference Product Exclusivity and 
Biosimilarity or Interchangeability Evaluations), an online resource 
that lists all FDA-licensed biological products by their nonproprietary 
name and clearly identifies products that have been approved as 
biosimilar to or interchangeable with a particular reference product.
2. Pharmacovigilance
    The Agency considers appropriate pharmacovigilance fundamentally 
important for all biological products. Although safety of drug and 
biological products is rigorously assessed prior to approval, safety 
issues that are specific to a manufacturer may arise after approval 
with any marketed product. Therefore, a robust pharmacovigilance 
program is essential to help ensure patient safety. To ensure continued 
safety of a biological product, appropriate pharmacovigilance 
necessitates that FDA be able to track adverse events to a specific 
manufacturer (and, as appropriate, site or lot for a particular 
biological product), and that surveillance systems be able to detect 
safety signals throughout the lifecycle of a product, so that the 
Agency and the manufacturer

[[Page 52227]]

can act swiftly and in a targeted manner to identify and address a 
problem.
    Pharmacovigilance systems, both active and passive, vary in their 
use of identifiers to differentiate among biological products; these 
identifiers may include the brand (proprietary) name, proper 
(nonproprietary) name, manufacturer, national drug code (NDC) number, 
lot number, and billing codes. Successful use of active 
pharmacovigilance systems (such as FDA's Sentinel system) for adverse 
event tracking relies on the standardized coding systems for capturing 
drug information in administrative and health care claims and billing 
records. These coding systems may vary based on the setting in which a 
drug is dispensed. Many therapeutic biological products are 
administered in settings, such as physician offices, clinics, or 
hospitals, where the administrative and billing data do not routinely 
include product identifiers such as brand name, manufacturer, NDC 
number, or lot number (Refs. 3 and 4). Thus, active pharmacovigilance 
systems that use administrative and billing data currently have limited 
ability to track biological products that share the same nonproprietary 
name to the manufacturer.
    Similarly, in many passive pharmacovigilance systems, proprietary 
names and NDC numbers are often not included in adverse event reports 
(Refs. 5 and 6). FDA uses the FDA Adverse Event Reporting System, a 
``passive'' surveillance system that compiles mandatory adverse event 
reports from manufacturers and voluntary reports submitted directly to 
FDA by health care professionals and patients. FDA requires 
manufacturers and others with mandatory reporting obligations to submit 
an adverse event report to FDA when a minimum of four elements 
(identifiable patient, identifiable reporter, suspect product, and an 
event or fatal outcome) are present, even if other required elements, 
such as NDC numbers, are not available. It is well known that many 
reports lack key information and that the information identifying 
products in spontaneous reports can be unreliable (Ref. 6). Proprietary 
names, even when included, may not reliably identify products in 
spontaneous adverse event reports since misattribution can occur with 
adverse event reporting. Furthermore, because national health care 
systems, health care professional organizations, and patient safety 
organizations recommend the use of nonproprietary names for prescribing 
and listing of drug products, the nonproprietary name may be the name 
used by some reporters to identify the drug products in the adverse 
event reports (Refs. 7 and 8). In addition, although NDC numbers can be 
used to identify manufacturer-specific information about a product, 
they are infrequently provided in spontaneous adverse event reports, 
and may not be available to the reporter at the time of reporting, or 
during followup with the reporter. As a result, the use of distinct 
proprietary names or NDC numbers is currently insufficient to address 
all concerns regarding pharmacovigilance. Distinguishable 
nonproprietary names for the biological products in this rulemaking 
would provide another critical tool in uniquely identifying these 
biological products. Use of such names for the biological products in 
this rulemaking would preserve the ability to detect both product-
specific safety signals and class effects, and would facilitate prompt 
evaluation of safety signals in passive and active postmarketing 
surveillance systems.
    Although FDA believes the use of distinguishable nonproprietary 
names for originator biological products, related biological products, 
and biosimilar products could improve pharmacovigilance, FDA is 
interested in comments addressing whether any potential alternative 
approaches such as increased use of NDC numbers and/or other tracking 
information would also improve pharmacovigilance of these products.
3. Additional Benefits of Consistent Naming Convention for These 
Biological Products
    FDA believes that it is important to initiate and encourage routine 
usage of designated suffixes in ordering, prescribing, dispensing, 
recordkeeping, and pharmacovigilance practices for these six biological 
products. The designated suffix would provide a consistent, readily 
available, and recognizable mechanism for health care professionals 
(including providers and pharmacists) and patients to correctly 
identify these biological products, regardless of their licensure 
pathway. The consistent use of a designated suffix for these biological 
products would remove ambiguity about the identity of the intended 
biological product. If a core name was used without such identifier, it 
may be unclear whether the originator product, a related biological 
product, or a biosimilar product was intended to be ordered, 
prescribed, dispensed, administered, or reported.
    This naming convention would have the added benefit of avoiding 
inaccurate perceptions of the safety and effectiveness of biological 
products based on their licensure pathway. The safety and effectiveness 
of biological products is rigorously assessed before approval. A number 
of comments have expressed concern that requiring distinguishable 
proper names only for biosimilar products would adversely affect health 
care provider and patient use of these new products (Ref. 9). FDA 
shares the concern that such an approach could lead to inaccurate and 
scientifically unfounded assertions of inferiority or clinically 
meaningful differences of an approved biosimilar product for its 
approved indications. FDA anticipates that use of proper names with 
designated suffixes for these originator biological products, related 
biological products, and biosimilar products, irrespective of their 
licensure pathway, would help avoid any inaccurate perceptions of the 
safety and effectiveness of biological products based on licensure 
pathway and thus address concerns raised by the comments.

B. Designation of Official Names and Proper Names for Certain 
Biological Products

    We are proposing to add subpart B on Designated Names and proposed 
Sec.  299.20 (21 CFR 299.20) to designate the official names and proper 
names of certain biological products. The six biological products 
included in proposed Sec.  299.20 have been selected because they fall 
under one of the following categories: (1) Reference product for an 
approved or publicly disclosed section 351(k) application (i.e., 
filgrastim (BLA 103353), epoetin alfa (BLA 103234), infliximab (BLA 
103772), and pegfilgrastim (BLA 125031)); (2) related biological 
product to one of these reference products (i.e., tbo-filgrastim (BLA 
125294)); or (3) biosimilar product (i.e., filgrastim-sndz (BLA 
125553)).
    We are proposing to designate the official name of ``filgrastim-
jcwp'' for the biological product licensed under BLA 103353, held by 
Amgen, Inc. (Amgen) and to change the proper name designated in the 
license from ``filgrastim'' to ``filgrastim-jcwp.'' Filgrastim, 
marketed as NEUPOGEN, is the reference product for ZARXIO (filgrastim-
sndz), a biosimilar product recently licensed under section 351(k) of 
the PHS Act.
    We also are proposing to designate the official name of 
``filgrastim-vkzt'' for the biological product licensed under BLA 
125294, held by Sicor Biotech, UAB, and to change the proper name 
designated in the license from ``tbo-filgrastim'' to ``filgrastim-
vkzt.'' Tbo-filgrastim, marketed as GRANIX, is a related biological 
product. FDA has

[[Page 52228]]

determined that the current names of filgrastim and tbo-filgrastim are 
not useful within the meaning of section 508 of the FD&C Act. Although 
these products are distinguished from each other and from filgrastim-
sndz, FDA believes that the addition of a distinguishing suffix to both 
names, and the elimination of the prefix from tbo-filgrastim, would 
avoid confusion regarding these products' relationships to one another 
and to filgrastim-sndz. The placement of the identifier as a suffix 
should result in an originator product, a related biological product, 
and a biosimilar product being grouped together in electronic 
databases, yet remaining distinguishable, which should help health care 
providers identify these products. Also, assignment of suffixes to all 
filgrastim products would help avoid a potential inaccurate perception 
that filgrastim-sndz, or any other biosimilar product that may be 
licensed in the future, differs in a clinically meaningful way from its 
reference product or is inferior for its approved conditions of use.
    In addition, we are proposing to designate the official name of 
``filgrastim-bflm'' for the biological product licensed under BLA 
125553, held by Sandoz, Inc., and to change the proper name designated 
in the license from ``filgrastim-sndz'' to ``filgrastim-bflm.'' 
Filgrastim-sndz, marketed as ZARXIO, is a biosimilar product recently 
licensed under section 351(k) of the PHS Act, and the distinguishing 
suffix designated at the time of licensure was derived from the name of 
the license holder. In light of FDA's current proposal to designate 
official names and proper names for five other biological products that 
would include distinguishing suffixes devoid of meaning, in the 
interest of usefulness and simplicity the name ``filgrastim-bflm'' 
should be designated as the official name and the proper name and 
codified with the names designated for filgrastim and tbo-filgrastim in 
proposed Sec.  299.20.
    We are proposing to designate the official names and change the 
proper names for three other reference products for section 351(k) 
applications that have been publicly disclosed. These reference 
products are epoetin alfa (BLA 103234), infliximab (BLA 103772), and 
pegfilgrastim (BLA 125031). We are proposing to designate the official 
name of ``epoetin alfa-cgkn'' for the biological product licensed under 
BLA 103234, held by Amgen and marketed as EPOGEN and PROCRIT, and to 
change the proper name designated in the license from ``epoetin alfa'' 
to ``epoetin alfa-cgkn.'' We also are proposing to designate the 
official name of ``infliximab-hjmt'' for the biological product 
licensed under BLA 103772, held by Janssen Biotech, Inc. and marketed 
as REMICADE, and to change the proper name designated in the license 
from ``infliximab'' to ``infliximab-hjmt.'' Finally, we are proposing 
to designate the official name of ``pegfilgrastim-ljfd'' for the 
biological product licensed under BLA 125031, held by Amgen and 
marketed as NEULASTA, and to change the proper name designated in the 
license from ``pegfilgrastim'' to ``pegfilgrastim-ljfd.''
    FDA has determined that the current names of ``epoetin alfa,'' 
``infliximab,'' and ``pegfilgrastim'' are not useful within the meaning 
of section 508 of the FD&C Act. Considerations similar to those 
described for filgrastim and tbo-filgrastim warrant the designation of 
official names and proper names that include distinguishing suffixes 
for pegfilgrastim, epoetin alfa, and infliximab. These products are the 
reference products for publicly disclosed applications under section 
351(k) of the PHS Act (Ref. 10). FDA believes that it is important to 
initiate and encourage routine usage of designated suffixes in 
ordering, prescribing, dispensing, recordkeeping, and pharmacovigilance 
practices for these products. Also, in the event that a biosimilar 
product is approved that relies upon one of these products as a 
reference product, assignment of designated suffixes to the reference 
products would help avoid potential inaccurate perceptions that any 
biosimilar product with a proper name that features a distinguishing 
suffix differs in a clinically meaningful way or is inferior for its 
approved conditions of use. Accordingly, in the interest of usefulness 
and simplicity, FDA is proposing to designate official names with 
designated suffixes that would also be designated as the proper names 
for these products.
    The official names and proper names in proposed Sec.  299.20 
include designated suffixes composed of four lowercase letters. The 
official names and proper names, if finalized, will appear on all 
labeling and marketing materials for these products where the product's 
proper name or drug substance name is provided.
    In addition, FDA also has determined that the following alternative 
names that include distinguishing suffixes devoid of meaning may be 
acceptable for these products: epoetin alfa-mkdv, filgrastim-gknh, 
filgrastim-kbhj, filgrastim-zbdt, infliximab-djfg, and pegfilgrastim-
vjbk.
    FDA is also considering an alternative nonproprietary naming format 
for biological products in which the suffix attached to the core name 
would be derived from the name of the license holder listed on the 
license. Under this alternative naming format, the official names and 
proper names for the six products that are the subject of this proposed 
rule could be as follows:

----------------------------------------------------------------------------------------------------------------
             BLA Number and holder                                Official name and proper name
----------------------------------------------------------------------------------------------------------------
103234, Amgen, Inc.............................  epoetin alfa-amgn.
103353, Amgen, Inc.............................  filgrastim-amgn.
125553, Sandoz, Inc............................  filgrastim-sndz.
125294, Sicor Biotech UAB......................  filgrastim-srbt.
103772, Janssen Biotech, Inc...................  infliximab-jnsn.
125031, Amgen, Inc.............................  pegfilgrastim-amgn.
----------------------------------------------------------------------------------------------------------------

    Each of the official names and proper names in proposed Sec.  
299.20 and each the alternative official names and proper names 
discussed previously was rigorously evaluated and determined unlikely 
to be a source of errors. Each of these official names and proper names 
(core name-suffix) would be sufficiently distinct from the 
nonproprietary names of other products. The designated suffixes are 
distinct from other drug substance names, do not look similar to the 
names of other currently marketed products, are sufficiently distinct 
from other suffix designations, and do not include any abbreviations 
commonly used in clinical practice in a manner that may lead the suffix 
to be misinterpreted as another element on the prescription or order.
    While alternative official names and proper names are described in 
this preamble to the proposed rule, the final rule would designate a 
single official name that also would be designated as the proper name 
for each product.

[[Page 52229]]

    FDA invites comment on the proposed official names and proper names 
for these products, including the alternative names listed previously 
and any other proposed names containing suffixes composed of four 
lowercase letters that would accomplish the objectives stated in this 
document. In particular, FDA invites comment on the benefits and 
challenges of designating a distinguishing suffix that is unique to 
each of these six biological products versus designating a 
distinguishing suffix that is shared by each product manufactured by a 
single license holder (i.e., the three biological products manufactured 
by Amgen). FDA also invites comment on whether meaningful suffixes 
(e.g., suffixes derived from the names of the license holders) would be 
expected to be more memorable or useful to health care providers or 
patients than suffixes devoid of meaning, and therefore be more useful 
for facilitating the safe use and appropriate pharmacovigilance of 
these products. FDA further requests comment on whether meaningful 
suffixes derived from the name of the license holder might create 
inappropriate market advantages that would impede biosimilar products' 
acceptance in the market.
    Following approval of a BLA supplement to update product labeling 
with the official name and proper name designated in any final rule, 
FDA would take steps to ensure that its drug listings that interface 
with other databases and systems reflect the newly designated 
nonproprietary name. FDA also would work with other governmental 
organizations and external stakeholders that play a role in national 
drug naming or listings to help ensure that the official name and 
proper name for the product is displayed accurately in drug listing 
systems. We invite comment on the best means of coordinating with 
external stakeholders that play a role in drug naming and listing to 
achieve this objective considering, among other things, any transition 
period before market availability of products labeled with the newly 
designated nonproprietary names.

III. Legal Authority

    Section 508 of the FD&C Act and section 351 of the PHS Act serve as 
the principal legal authorities for this proposed rule. Section 508 of 
the FD&C Act, which applies to biological products pursuant to section 
351(j) of the PHS Act, provides FDA with authority to designate 
official names for drugs if it determines that such action is necessary 
or desirable in the interest of usefulness and simplicity. For the 
reasons described previously, FDA has determined that the interest of 
usefulness and simplicity warrants the designation of official names 
for the products included in this rulemaking. FDA also has authority 
under section 351(a) of the PHS Act to designate the proper name of a 
biological product and may do so through rulemaking. FDA is exercising 
this authority to designate matching proper names for these products.
    Thus, section 508 of FD&C Act and section 351 of the PHS Act, in 
conjunction with FDA's general rulemaking authority in section 701(a) 
of the FD&C Act (21 U.S.C. 371(a)), provide legal authority for this 
proposed rule.

IV. Effective Date

    FDA proposes that any final rule that may be issued based on this 
proposal become effective 90 days after the date of its publication in 
the Federal Register. During the 90-day period after publication of any 
final rule, FDA expects that BLA holders for these six products would 
submit a prior approval supplement to their BLA to update the labeling 
of their product. After approval of the supplement, FDA intends to work 
with sponsors to minimize any manufacturing and distribution 
disruptions related to the implementation of new labeling and any 
related marketing materials. FDA expects that manufacturers will 
implement the new labeling at the time of their next manufacturing run 
and does not intend to object to manufacturers exhausting existing 
inventories of finished product that is not labeled with the official 
names and proper names designated by this rule.

V. Environmental Impact

    The Agency has determined under 21 CFR 25.30(h) and (k) and 
25.31(a) that this action is of a type that does not individually or 
cumulatively have a significant effect on the human environment. 
Therefore, neither an environmental assessment nor an environmental 
impact statement is required.

VI. Economic Analysis of Impacts: Summary

    FDA has examined the impacts of the proposed rule under Executive 
Order 12866, Executive Order 13563, the Regulatory Flexibility Act (5 
U.S.C. 601-612), and the Unfunded Mandates Reform Act of 1995 (Pub. L. 
104-4). Executive Orders 12866 and 13563 direct Agencies to assess all 
costs and benefits of available regulatory alternatives and, when 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety, and other advantages; distributive impacts; and 
equity). The Office of Management and Budget (OMB) has determined that 
this proposed rule is a significant regulatory action as defined by 
Executive Order 12866.
    The Regulatory Flexibility Act requires Agencies to analyze 
regulatory options that would minimize any significant impact of a rule 
on small entities. Because the proposed rule imposes one-time 
relabeling costs on one small business, the Agency proposes to certify 
that the final rule will not have a significant economic impact on a 
substantial number of small entities.
    Section 202(a) of the Unfunded Mandates Reform Act of 1995 requires 
that Agencies prepare a written statement, which includes an assessment 
of anticipated costs and benefits, before proposing ``any rule that 
includes any Federal mandate that may result in the expenditure by 
State, local, and tribal governments, in the aggregate, or by the 
private sector, of $100,000,000 or more (adjusted annually for 
inflation) in any one year.'' The current threshold after adjustment 
for inflation is $144 million, using the most current (2014) Implicit 
Price Deflator for the Gross Domestic Product. FDA does not expect this 
proposed rule to result in any 1-year expenditure that would meet or 
exceed this amount.
    We estimate the one-time costs of learning about the rule; 
submitting labeling supplements, forms, and revised marketing materials 
to FDA; changing labeling on affected products; FDA review of labeling 
supplements, forms, and revised marketing materials; and activities to 
educate practitioners about name changes. The one-time costs range from 
$0.78 million to $3.04 million. Over 10 years, the annualized costs 
range from $0.10 million to $0.40 million with a 7 percent discount 
rate, and from $0.09 million to $0.35 million with a 3 percent discount 
rate.
    We expect the rule would have other costs that are not yet included 
in these estimated costs. Additional costs to industry may include 
costs updating prescribing and reimbursement systems to reflect the new 
names and changing marketing materials to reflect the new names.
    We lack data to quantify the benefits of the proposed rule. In the 
event of biosimilar entry, the name changes for certain products that 
would be required by this proposed rule may help mitigate a potential 
competitive disadvantage for

[[Page 52230]]

biosimilar products that receive a nonproprietary name that includes a 
distinguishing suffix. More competition between the biosimilar product 
and the reference product may reduce the price and increase the usage 
of those products. The proposed rule may also encourage the routine use 
of suffixes for these six biological products, which may facilitate 
more accurate prescribing and monitoring of these six biological 
products if biosimilar products enter the market.

accordance with Executive Order 12866, Executive Order 13563, the 
Regulatory Flexibility Act, and the Unfunded Mandates Reform Act is 
available at http://www.regulations.gov under Docket No. FDA-2015-N-
0648 and at http://www.fda.gov/AboutFDA/ReportsManualsForms/Reports/EconomicAnalyses/default.htm (Ref. 11).

VII. Paperwork Reduction Act of 1995

    FDA tentatively concludes that this proposed rule contains no new 
collection of information. The official names and proper names of each 
of these biological products, as designated by the proposed rule, would 
be information originally supplied by the Federal government to the 
recipient for the purpose of disclosure to the public, and the public 
disclosure of such information is not a ``collection of information'' 
within the meaning of the Paperwork Reduction Act of 1995 (the PRA). 
See 5 CFR 1320.3(c)(2). Therefore, clearance by the OMB under the PRA 
(44 U.S.C. 3501-3520) is not required.
    The discussion of effective date in the preamble (section IV) to 
this proposed rule references certain actions that would be taken by 
manufacturers and applicants for the specific approved biological 
products for which this proposed rule would designate official names 
and proper names, in order to comply with existing FDA regulations that 
contain collections of information that are subject to review by OMB 
under the PRA.
    Specifically, prior to the effective date of any final rule based 
on this proposal, a prior approval supplement would be submitted in 
accordance with Sec.  601.12 (21 CFR 601.12) for each of six specific 
BLAs referenced in this rule, to update the labeling of the product 
(which includes the immediate container label and outer container or 
package) with the designated official name and proper name. The 
submission of supplements to approved license applications under Sec.  
601.12 is approved under OMB control number 0910-0338. We estimate that 
this rulemaking would result in the one-time submission of six 
supplements. In conjunction with our previously approved collection of 
information under Sec.  601.12, we estimated that each such supplement 
would incur a burden of 40 hours.
    The discussion of effective date also acknowledges that these 
applicants would revise their labeling, which includes the immediate 
container label and outer container or package, to reflect the newly 
designated official names and proper names. (As noted, disclosing the 
official names and proper names of each of these biological products to 
the public is not a ``collection of information'' within the meaning of 
the PRA. See 5 CFR 1320.3(c)(2).) The design and testing of 
prescription drug labeling required under Sec. Sec.  201.56 and 201.57 
(21 CFR 201.56 and 201.57) (including Sec.  201.56(a)(2)) is approved 
under OMB control number 0910-0572. Concerning the immediate container 
label and outer container or package, in the Federal Register of 
December 18, 2014 (79 FR 75506), we published a proposed rule on the 
electronic distribution of prescribing information for human 
prescription drugs, including biological products. In section VII, 
``Paperwork Reduction Act of 1995,'' we estimated the burden to design 
(including revisions), test, and produce the label for a drug's 
immediate container and outer container or package, as set forth in 21 
CFR part 201 and other sections in subpart A and subpart B.

VIII. Comments

    Interested persons may submit either electronic comments regarding 
this document to http://www.regulations.gov or written comments to the 
Division of Dockets Management (see ADDRESSES). It is only necessary to 
send one set of comments. Identify comments with the docket number 
found in brackets in the heading of this document. Received comments 
may be seen in the Division of Dockets Management between 9 a.m. and 4 
p.m., Monday through Friday, and will be posted to the docket at http://www.regulations.gov.

IX. Federalism

    FDA has analyzed this proposed rule in accordance with the 
principles set forth in Executive Order 13132. FDA has determined that 
the proposed rule, if finalized, would not contain policies that would 
have substantial direct effects on the States, on the relationship 
between the National Government and the States, or on the distribution 
of power and responsibilities among the various levels of government. 
Accordingly, the Agency tentatively concludes that the proposed rule 
does not contain policies that have federalism implications as defined 
in the Executive order and, consequently, a federalism summary impact 
statement is not required.

X. References
