Formal Meetings Between the FDA and Sponsors
or Applicants of BsUFA Products
Guidance for Industry1
This guidance represents the current thinking of the Food and Drug Administration (FDA or Agency) on
this topic. It does not establish any rights for any person and is not binding on FDA or the public. You
can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
To discuss an alternative approach, contact the FDA staff responsible for this guidance as listed on the
title page.
I. 	INTRODUCTION
This guidance provides recommendations to industry on formal meetings between the Food and
Drug Administration (FDA) and sponsors or applicants relating to the development and review
of proposed biosimilar, including interchangeable biosimilar, products2 regulated by the Center
for Drug Evaluation and Research (CDER) or the Center for Biologics Evaluation and Research
(CBER).
This guidance does not apply to meetings associated with the development of products intended
for submission in, or with the review of, new drug applications or abbreviated new drug
applications under section 505 of the Federal Food, Drug and Cosmetic Act (FD&C Act) (21
U.S.C. 355), biologics license applications (BLAs) under section 351(a) of the Public Health
Service Act (PHS Act) (42 U.S.C. 262(a)),3 or submissions for devices under the FD&C Act.4
1 This guidance has been prepared by the Center for Drug Evaluation and Research in cooperation with the Center
for Biologics Evaluation and Research at the Food and Drug Administration.
2 In this guidance, the following terms are used to describe biological products licensed under section 351(k) of the
PHS Act: (1) “biosimilar” or “biosimilar product” refers to a product that the FDA has determined to be biosimilar
to the reference product (see sections 351(i)(2) and 351(k)(2) of the PHS Act) and (2) “interchangeable biosimilar”
or “interchangeable product” refers to a biosimilar product that the FDA has determined to be interchangeable with
the reference product (see sections 351(i)(3) and 351(k)(4) of the PHS Act).
3 For information on meetings for new drug applications and 351(a) BLAs, see the draft guidance for industry
Formal Meetings Between the FDA and Sponsors or Applicants of PDUFA Products (September 2023). When
final, this guidance will represent the FDA’s current thinking on this topic. For the most recent version of a
guidance, check the FDA guidance web page at https://www.fda.gov/regulatory-information/search-fda-guidance-
documents.
4 For information on meetings for medical device submissions, see the draft guidance for industry Requests for
Feedback and Meetings for Medical Device Submissions: The Q-Submission Program (March 2024). When final,
this guidance will represent the FDA’s current thinking on this topic.
Contains Nonbinding Recommendations
2
For the purposes of this guidance, formal meeting includes any meeting that is requested by a
sponsor or applicant (hereafter referred to as requester(s)) following the procedures provided in
this guidance and includes meetings conducted in any format (i.e., in-person, virtual
(videoconference), teleconference, or written response only (WRO)).
This guidance discusses the principles of good meeting management practices and describes
standardized procedures for requesting, preparing, scheduling, conducting, and documenting
such formal meetings.5
This guidance finalizes the draft guidance of the same name issued in August 2023.
In general, FDA’s guidance documents do not establish legally enforceable responsibilities.
Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only
as recommendations, unless specific regulatory or statutory requirements are cited. The use of
the word should in Agency guidances means that something is suggested or recommended, but
not required.
II. 	BACKGROUND
Each year, FDA review staff participate in many meetings with requesters who seek advice
relating to the development and review of a proposed biosimilar, including interchangeable
biosimilar, product. Because these meetings often represent critical points in the regulatory and
development process, it is important that there are efficient, consistent procedures for the timely
and effective conduct of such meetings. The good meeting management practices in this
guidance are intended to provide consistent procedures that will promote well-managed meetings
and to ensure that such meetings are scheduled within a reasonable time, conducted efficiently,
and documented appropriately.
As part of the reauthorization of the Biosimilar User Fee Act (BsUFA), the FDA has committed
to specific performance goals that include meeting management goals for formal meetings that
occur between the FDA and requesters.6
5 The guidance for industry Formal Meetings Between the FDA and Biosimilar Biological Product Sponsors or
Applicants (November 2015) has been withdrawn.
6 See BsUFA III goals letter titled “Biosimilar Biological Product Reauthorization Performance Goals and
Procedures Fiscal Years 2023 Through 2027,” available on the FDA website at

III. 	MEETING TYPES7
There are six types of formal meetings that occur between requesters and FDA staff to discuss
development and review of a proposed biosimilar, including interchangeable biosimilar, product:
Biosimilar Initial Advisory (BIA), Biosimilar Biological Product Development (BPD) Type 1,
BPD Type 2a, BPD Type 2b, BPD Type 3, and BPD Type 4.
A. 	BIA Meeting
A BIA meeting is an initial assessment limited to a general discussion regarding whether
licensure under section 351(k) of the PHS Act may be feasible for a particular product, and if so,
general advice on the expected content of the development program as it relates to the
biosimilarity assessment. This meeting type does not involve substantive review of summary
data or full study reports. Although the FDA encourages requesters to provide analytical data
from at least one lot of the proposed biosimilar or interchangeable biosimilar product compared
to the U.S.-licensed reference product, the data are not required as long as the requester provides
sufficient information with the meeting request to enable the FDA to make a preliminary
determination as to whether licensure under section 351(k) of the PHS Act may be feasible for a
particular product and to provide meaningful advice. The meeting request should include the
following, as appropriate:
• 	Identification of reference product.
• 	The indications intended to be sought for licensure.
• 	A comparative analytical assessment plan, including preliminary identification of the
critical quality attributes and planned characterization methods.
• 	If a requester seeks to use a non-U.S.-licensed comparator product during development,
the proposed bridging strategy to justify the relevance of the data generated with the non-
U.S.-licensed comparator product.
• 	A conceptual description of the planned clinical pharmacokinetics and/or
pharmacodynamic study or studies, including proposed endpoints.
• 	A conceptual plan that includes initial considerations regarding the need for a
comparative clinical study. If the requester plans to conduct a comparative clinical safety
and efficacy study, this conceptual plan should include the patient population and
proposed endpoints.
• 	Any guidance already received from other health authorities on product development.
7 The meeting types and goal dates are described in the BsUFA III goals letter and apply to formal meetings between
FDA staff and requesters of BsUFA meetings; they do not apply to meetings with CDER’s Office of Generic Drugs,
CDER’s Office of Compliance, or CDER’s Office of Prescription Drug Promotion.
Contains Nonbinding Recommendations
4
• 	Identification to the FDA of the regulatory status in other jurisdictions.
Extensive analytical, nonclinical, and/or clinical data are not expected to be provided based on
the expected stage of development of the proposed biosimilar, including interchangeable
biosimilar, product. If the requester is seeking targeted advice on the adequacy of any
comparative data or extensive advice for any aspect of a planned or ongoing biosimilar,
including interchangeable biosimilar, product development program, a different meeting type
should be requested. Requesting a BIA meeting is not a requirement prior to joining the BPD
program.
B. 	BPD Type 1 Meeting
A BPD Type 1 meeting is a meeting that is necessary for an otherwise stalled development
program to proceed or a meeting to address an important safety issue. Examples of a BPD Type
1 meeting include the following:
• 	Meetings to discuss clinical holds in which (1) the requester seeks input on how to
address the hold issues; or (2) a response to hold issues has been submitted and reviewed
by the FDA, but the FDA and the requester agree that the development is stalled and a
new path forward should be discussed.
• 	Meetings that are requested after receipt of an FDA nonagreement special protocol
assessment letter in response to protocols submitted under the special protocol
assessment procedures as described in the guidance for industry Special Protocol
Assessment (April 2018).
• 	Meetings to discuss an important safety issue, when such an issue is identified and the
FDA and requester agree that the issue should be discussed.
• 	Dispute resolution meetings as described in 21 CFR 10.75 and 312.48 and in the
guidance for industry and review staff Formal Dispute Resolution: Sponsor Appeals
Above the Division Level (November 2017).8
• 	Post-action meetings requested after an FDA regulatory action other than an approval
(i.e., issuance of a complete response letter).
• 	Meetings requested within 30 days of FDA issuance of a refuse-to-file letter to discuss
whether the FDA should file the application.
C. 	BPD Type 2a Meeting
A BPD Type 2a meeting is a meeting focused on a narrow set of issues (e.g., often one but not
more than two issues and associated questions) requiring input from no more than three

5
disciplines or review divisions. To request a BPD Type 2a meeting, requesters must first have
had a BIA or another BPD meeting type with the FDA.9 Examples of such discussion issues
could include the following:
• 	Immunogenicity testing strategy following prior FDA recommendations or feedback.
• 	A request for feedback on an updated study design when the revisions are based on prior
FDA feedback.
• 	Defined chemistry, manufacturing, and controls (CMC) postapproval commitments (e.g.,
related to analytical methods) discussing the approach in advance of conducting the study
to ensure the approach is in line with the FDA’s expectations.
D. 	BPD Type 2b Meeting
A BPD Type 2b10 meeting is a meeting to discuss a specific issue (e.g., ranking of quality
attributes, CMC issue such as control strategy, study design or endpoints, postapproval changes)
or questions for which the FDA will provide targeted advice regarding an ongoing development
program. This meeting type may include substantive review of summary data but does not
include review of full study reports.
E. 	BPD Type 3 Meeting
A BPD Type 3 meeting is an in-depth data review and advice meeting regarding an ongoing
development program. This meeting type includes substantive review of full study reports (e.g.,
detailed and robust analytical similarity data or clinical study reports), FDA advice regarding
similarity between the proposed biosimilar, including interchangeable biosimilar, product and the
reference product, and FDA advice regarding the need for additional studies, including design
and analysis.
• 	Examples of a BPD Type 3 meeting submission include the following:
– 	Comprehensive analytical similarity data sufficient for the FDA to make a
preliminary evaluation of analytical similarity. The level of analytical data provided
should be similar to what the requester intends to submit in a 351(k) BLA (e.g., full
study reports and/or datasets that support the full study reports).
– 	Full study report(s) for a clinical study or studies.
9 Section I.H. of the BsUFA III goals letter.
10 A BPD Type 2b meeting under BsUFA III has the same scope as a BPD Type 2 meeting under BsUFA II;
accordingly, the FDA considers a BPD Type 2b meeting to be broader in scope than a BPD Type 2a meeting.
Contains Nonbinding Recommendations
6
• 	Examples of topics on which the requester can seek FDA advice as part of a BPD Type 3
meeting, in addition to a discussion of the in-depth data described above, include the
following:
– 	Proposal for any additional planned studies
– 	Proposal for justification of extrapolation
F. 	BPD Type 4 Meeting
A BPD Type 4 meeting is a presubmission meeting to discuss the format and content of a
complete original application under the Program for Enhanced Review Transparency and
Communication for Original 351(k) BLAs (also known as the Program)11 or supplement
submitted under 351(k) of the PHS Act for a proposed biosimilar, including interchangeable
biosimilar, product. The purpose of this meeting is to discuss the format and content of the
planned submission and other items, including the following:
• 	Identification of those studies that the requester is relying on to support a demonstration
of biosimilarity or interchangeability
• 	Discussion of any potential review issues identified based on the information provided
• 	Identification of the status of pediatric assessments to adequately address the Pediatric
Research Equity Act (PREA)
• 	Acquainting FDA reviewers with the general information to be submitted in the
marketing application (including technical information)
• 	Discussion of the best approach to the presentation and formatting of data in the
marketing application
IV. 	BsUFA FEES ASSOCIATED WITH THE BPD PROGRAM
Under the BsUFA user fee provisions of the FD&C Act, BPD fees are assessed for products in
the BPD program. BPD fees include the initial BPD fee, the annual BPD fee, and the
reactivation fee. No fee is associated with a BIA meeting. For more information about BsUFA
fees, including the assessment of BPD fees and the consequences for failure to pay any required
BPD fees, refer to the guidance for industry Assessing User Fees Under the Biosimilar User Fee
Amendments of 2022 (July 2023).

V. 	MEETING FORMATS
There are four meeting formats: in-person, virtual (videoconference), teleconference, and WRO
as follows:
1. 	Face-to-Face:
a. 	In-person: Core attendees12 from the FDA and the sponsor/applicant participate in
person at the FDA; such meetings will be hybrid with a virtual component to allow non-
core participants to join virtually. Because the intent is that the primary discussion occurs
face-to-face in person, all sponsors and FDA individuals who are key to such discussions
(i.e., “core” attendees) should participate, if feasible, in person. Individuals expected to
have a more peripheral role (e.g., may be called on to comment on a single question) may
participate virtually. If core sponsor personnel are suddenly unable to attend the in person
meeting due to illness or unexpected travel issues, they can join the meeting virtually. If
core sponsor personnel are not planning to attend in person, the meeting should be
requested as a virtual face-to-face meeting.
b. 	Virtual (videoconference): Attendees participate from various remote locations via a
video and audio connection (e.g., with core attendees’ cameras on).
2. 	Teleconference: Attendees participate from various remote locations via an audio only
connection (e.g., telephone, virtual meeting platform without cameras on).
3. 	Written response only (WRO): WRO responses are sent to requesters in lieu of
meetings conducted in one of the three formats described above. Requesters may request
this meeting format only for BIA, BPD Type 2a, and BPD Type 2b meetings.
VI. 	MEETING REQUESTS
To make the most efficient use of FDA resources, before seeking a meeting, requesters should
consult the information publicly available from the FDA that relates to biosimilar, including
interchangeable biosimilar product development.13
To promote efficient meeting management, requesters should anticipate future needs and, to the
extent practical, combine related product development issues into the fewest possible meetings.
To request a meeting, submit a written request to the FDA via the respective center’s document
room (paper submissions) or via the electronic gateway, as appropriate. Written meeting
12 FDA expects to have its core participants with primary speaking roles participate in person while others may join
virtually (see https://www.fda.gov/industry/prescription-drug-user-fee-amendments/update-person-face-face-formal-
meetings-fda).
13 See the guidance for industry and review staff Best Practices for Communication Between IND Sponsors and
FDA During Drug Development (December 2017).
Contains Nonbinding Recommendations
8
requests must be made in accordance with any applicable electronic submission requirements.14
Meeting requests must be addressed to the appropriate review division or office to qualify for
meeting management performance goals15 and, if previously assigned, are expected to be
submitted to the pre-investigational new drug application (pre-IND) file or application (e.g.,
investigational new drug application (IND), BLA). The FDA considers meeting requests sent by
fax or email to be courtesy copies only and are not substitutes for formal submissions.
The requester should submit a meeting request for the development of a proposed biosimilar,
including interchangeable biosimilar, product with multiple indications that span multiple review
divisions to the division that has regulatory oversight of the reference product.
Requesters are not required to request meetings in sequential order (e.g., BIA, BPD Type 2a,
BPD Type 2b, BPD Type 3, then BPD Type 4). However, to request a Type 2a meeting,
requesters must first have had a BIA or another BPD meeting type with the FDA.16 The meeting
type requested depends on the stage of the development program and/or the advice sought. The
FDA will grant one BIA meeting for the development program of a particular proposed
biosimilar, including interchangeable biosimilar, product and, generally, one BPD Type 4
meeting for each application or supplement, as appropriate. The FDA will, as appropriate, grant
as many BPD Type 2a, BPD Type 2b, and BPD Type 3 meetings as are requested and considered
necessary to support the development and review of a proposed biosimilar, including
interchangeable biosimilar, product.
The meeting request should include adequate information for the FDA to assess the potential
utility of the meeting and to identify FDA staff necessary to discuss proposed agenda items.
The meeting request should include the following information:
1. 	Application number (if previously assigned).
2. 	Development-phase code name of product (if pre-licensure).
3. 	Proper name (if post-licensure).
4. 	Structure (if applicable).
5. 	Proper and proprietary names of the reference product.
6. 	Proposed indication(s) or context of product development.
14 See section 745A(a) of the FD&C Act; see also the guidances for industry Providing Regulatory Submissions in
Electronic Format — Submissions Under Section 745A(a) of the Federal Food, Drug, and Cosmetic Act (December
2014) and Providing Regulatory Submissions in Electronic Format — Certain Human Pharmaceutical Product
Applications and Related Submissions Using the eCTD Specifications (February 2020).

7. 	Pediatric study plans (if applicable).
8. 	Human factors engineering plan (if applicable).
9. 	Combination product information (e.g., constituent parts, including details of the device
constituent part, intended packaging, planned human factors studies) (if applicable).
The meeting request must include the following information for the performance goals
(described in section I.H., Meeting Management Goals, of the BsUFA III goals letter) to apply:
1. 	Meeting type being requested (i.e., BIA meeting, BPD Type 1, Type 2a, Type 2b, Type 3,
or Type 4 meeting). The rationale for requesting the meeting type should also be
included.
2. 	Proposed meeting format (i.e., in-person, virtual (videoconference), teleconference, or
WRO).
3. 	Brief statement of the purpose of the meeting. This statement should include a brief
background of the issues underlying the proposed agenda. It also can include a brief
summary of completed or planned studies or data that the requester intends to discuss at
the meeting, the general nature of the critical questions to be asked, and where the
meeting fits in overall development plans. Although the statement should not provide the
details of study designs or completed studies, it should provide enough information to
facilitate understanding of the issues, such as a small table that summarizes major results.
4. 	List of specific objectives or outcomes the requester expects from the meeting.
5. 	Proposed agenda, including estimated times needed for discussion of each agenda item.
6. 	List of questions, grouped by FDA discipline. For each question there should be a brief
explanation of the context and purpose of the question.
7. 	List of planned attendees from the requester’s organization, which should include their
names and titles. The list should also include names, titles, and affiliations of consultants
and interpreters (if applicable).
8. 	List of requested FDA attendees and/or discipline representative(s). Requests for
attendance by FDA staff who are not otherwise essential to the application’s review may
affect the ability to hold the meeting within the specified time frame of the meeting type
being requested. Therefore, when attendance by nonessential FDA staff is requested, the
meeting request should provide a justification for such attendees and state whether a later
meeting date is acceptable to the requester to accommodate the inclusion of nonessential
FDA attendees.
9. 	Suggested dates and times (e.g., morning, afternoon) for the meeting that are within or
beyond the appropriate scheduling time frame of the meeting type being requested (see
Contains Nonbinding Recommendations
10
Table 2 in section VII.B., Meeting Granted). Dates and times when the requester is not
available should also be included.
When submitting a meeting request, the requester should define the specific areas of input
needed from the FDA. A well-written meeting request that includes the above components can
help the FDA understand and assess the utility and timing of the meeting related to product
development or review. The list of planned attendees and the list of requested FDA attendees
can be useful in providing or preparing for the input needed at the meeting. However, during the
time between the request and the meeting, the planned attendees can change. If there are
changes, an updated list of attendees with their titles and affiliations should be provided to the
appropriate FDA contact at least 1 week before the meeting.
The objectives and agenda provide overall context for the meeting topics, but it is the list of
questions that is most critical to understanding the kind of information or input needed by the
requester and to focus the discussion should the meeting be granted. Each question should be
precise and include a brief explanation of the context and purpose of the question. The questions
submitted within a single meeting request should be limited to those that can be reasonably
answered within the allotted meeting time, taking into consideration the complexity of the
questions submitted. Similar considerations regarding the complexity of questions submitted
within a WRO should be applied. Based on experience, the maximum number of questions that
can be reasonably answered within the allotted meeting time is 10 questions (subquestions will
be counted as separate questions). Therefore, a meeting request should include no more than 10
questions listed consecutively regardless of discipline, and should include fewer than 10 if the
questions are more complex.
VII. 	ASSESSING AND RESPONDING TO MEETING REQUESTS
Although requesters must request a specific meeting type and format,17 the FDA assesses each
meeting request, including WRO requests for BIA, BPD Type 2a, and BPD Type 2b meetings,
and determines whether the request should be granted, the appropriate meeting type, and the
appropriate meeting format. The FDA honors requests for BPD Type 2b, BPD Type 3, and BPD
Type 4 meetings except in the most unusual circumstances. However, the FDA may determine
that a different type of meeting is more appropriate and may grant a different type of meeting
than is requested.18 Additionally, if the FDA determines that the WRO format is not appropriate
for a requested WRO meeting or that the face-to-face (i.e., in-person, virtual (videoconference))
or teleconference meeting format is not appropriate for a requested face-to-face or teleconference
meeting, the FDA will notify the requester that the meeting has been denied, as described in
section VII.A., Meeting Denied. However, if an in-person, virtual (videoconference), or
teleconference meeting format is requested for a BPD Type 2a meeting, but the FDA determines
17 BsUFA III goals letter.
18 If the FDA grants a meeting of a different type than requested, this may require the payment of a biosimilar
biological product development fee as described in section 744H of the FD&C Act before the meeting will be
conducted. If a biosimilar biological product development fee is required under section 744H, and the sponsor does
not pay the fee within the timeframe required under section 744H, the meeting will be cancelled.

11
that a written response to the questions would be the most appropriate format, the FDA will
notify the requester as described in section VII.B. Meeting Granted.
The meeting request must be accompanied by the meeting package for BIA, BPD Type 1, BPD
Type 2a, BPD Type 2b, and BPD Type 3 meetings (see section VIII.C., Meeting Package
Content, for additional information regarding the content of the meeting package).19 This
ensures that the FDA has adequate information to assess the potential utility of the meeting and
prepare for the meeting. If the meeting package is not submitted as described above, the FDA
will consider the meeting request incomplete and will generally deny the meeting request.
A. 	Meeting Denied
If a meeting request is denied, the FDA will notify the requester in writing according to the
timelines described in Table 1. These notifications include an explanation of the reason for the
denial. Denials are based on substantive reason, not merely on the absence of a minor element of
the meeting request or a minor element of the meeting package. For example, the FDA may
deny a meeting request because it is premature for the stage of product development, is clearly
unnecessary, or is not appropriate for the format requested (e.g., WRO versus in-person/virtual
(videoconference)/teleconference for BIA, BPD Type 2a, or BPD Type 2b meetings) or the
meeting package does not provide an adequate basis for the meeting discussion.
The FDA may also deny requests for meetings that do not have substantive information related
to the elements described in section VI., Meeting Requests. The FDA will consider a subsequent
request to schedule the meeting as a new request (i.e., a request that is assigned a new set of time
frames described below in section VII.B., Meeting Granted).
B. 	Meeting Granted
If a meeting request is granted, the FDA will notify the requester in writing according to the
timelines described in Table 1. For in-person, virtual (videoconference), or teleconference
meeting formats, these notifications include the date, time, conferencing arrangements and/or
location of the meeting, and expected FDA participants. For BIA, BPD Type 2a, and BPD Type
2b WRO meetings, these notifications include the date the FDA intends to send the written
response (see Table 3 for FDA WRO response timelines).
For the BPD Type 2a meeting, although the requester may request an in-person, virtual
(videoconference), or teleconference meeting format, the FDA may determine that a written
response to the requester’s questions would be the most appropriate means for providing
feedback and advice to the requester. When it is determined that the meeting request can be
appropriately addressed through a written response, the FDA will notify the requester of the
meeting format change in writing, and this notification will include the date the FDA intends to
send the written response in the Agency’s response to the meeting request (see Table 3 for FDA
WRO response timelines). If the requester believes an in-person, virtual (videoconference), or
teleconference BPD Type 2a meeting is valuable and warranted, then the requester may provide
rationale in a follow-up correspondence explaining why that meeting format is valuable and

warranted, and the FDA will reconsider this request. If the FDA agrees to grant the in-person,
virtual (videoconference), or teleconference meeting format, the Agency will strive to schedule
the meeting to occur within 60 calendar days of the FDA’s receipt of the meeting request.
For in-person, virtual (videoconference), or teleconference meeting formats, the FDA schedules
the meeting on the next available date at which all expected FDA staff are available to attend.
However, the meeting should be scheduled consistent with the type of meeting requested (see
Table 2 for FDA meeting scheduling time frames). If the requested date for any meeting type is
greater than the specified time frame, the meeting date should be within 14 calendar days of the
requested date.

VIII. 	MEETING PACKAGE
Premeeting preparation is critical for achieving a productive discussion or exchange of
information. Preparing the meeting background package should help the requester focus on
describing its principal areas of interest. The meeting package should provide information
relevant to the discussion topics and enable the FDA to prepare adequately for the meeting.
A. 	Timing of Meeting Package Submission
As discussed in section VII., Assessing and Responding to Meeting Requests, if the meeting
package is not submitted with the meeting request for BIA, BPD Type 1, BPD Type 2a, BPD
Type 2b, and BPD Type 3 meetings, the meeting request is considered incomplete, and the FDA
generally will deny the meeting. For BPD Type 4 meetings, the background package must be
received no later than 14 calendar days after the FDA’s receipt of the meeting request.20
B. 	Where and How Many Copies of Meeting Packages to Send
Requesters must submit a meeting package to the appropriate review division or office21 and, if
previously assigned, the meeting package is expected to be submitted to the relevant pre-IND file
or application(s) (e.g., IND, BLA). Meeting packages are expected to be submitted via the
appropriate center’s document room (paper submission) or electronic gateway, as applicable.
Submissions must be made in accordance with any applicable electronic submission
requirements.22
Occasionally, to facilitate the meeting process, CDER staff may request, in addition to the
electronic format, a limited number of meeting packages in paper format (desk copies). The
number of desk copies of a meeting package will vary based on the meeting. The CDER project
manager will advise on the number of desk copies needed for the meeting attendees. CBER
neither requests nor accepts paper copies (desk copies) of meeting packages that have been
submitted in electronic format.
C. 	Meeting Package Content
The meeting package should provide information relevant to the product, stage of development,
and meeting type requested (see section III., Meeting Types), in addition to any supplementary
information needed to develop responses to issues raised by the requester or review division.
The meeting package should contain sufficient details to meet the intended meeting objectives.
For example, inclusion of raw data in addition to the derived conclusions may be appropriate in
20 BsUFA III goals letter.

some situations. Similarly, merely describing a result as significant does not provide the review
division with enough information to give advice or identify important problems the requester
may have missed. FDA guidances identify and address many issues related to biosimilar,
including interchangeable biosimilar, product development, and requesters should consider these
when planning, developing, and providing information needed to support a meeting with the
FDA.23 If a product development plan adopts an alternative approach from that recommended in
FDA guidance, the alternative approach should be identified and explained. Known or expected
difficult design and evidence issues should be raised for discussion (e.g., selection of study
populations, doses, or endpoints different from those studied for the reference product’s
licensure; extrapolation of data and information).
To facilitate FDA review, the meeting package content should be organized according to the
proposed agenda. The meeting package should be a sequentially paginated document with a
table of contents, appropriate indices, appendices, and cross-references. It should be tabbed or
bookmarked to enhance reviewers’ navigation across different sections within the package, both
in preparation for and during the meeting. Meeting packages generally should include the
following information in the order listed below:
1. 	Application number (if previously assigned).
2. 	Development-phase code name of product (if pre-licensure).
3. 	Proper name (if post-licensure).
4. 	Structure (if applicable).
5. 	Proper and proprietary names of the reference product.
6. 	Proposed indication(s) or context of product development.
7. 	Dosage form, route of administration, dosing regimen (frequency and duration), strength,
and presentation(s).
8. 	Pediatric study plans (if applicable).
9. 	Human factors engineering plan (if applicable).
10. Combination product information (e.g., constituent parts, including details of the device
constituent part, intended packaging, planned human factors studies) (if applicable).
11. List of planned attendees, including titles and affiliations, from the requester’s
organization, including consultants and interpreters (if applicable).

https://www.fda.gov/drugs/biosimilars/industry-information-and-guidance.

12. Background section that includes the following:
a. 	Brief history of the development program and relevant communications with the FDA
before the meeting.
b. 	Substantive changes in product development plans (e.g., manufacturing changes, new
study population or endpoint) (when applicable).
c. 	Status of product development (e.g., CMC; nonclinical; clinical, including any
development outside the United States, as applicable).
13. Brief statement summarizing the purpose of the meeting.
14. Proposed agenda, including estimated times needed for discussion of each agenda item.
15. List of questions for discussion, grouped by FDA discipline and with a brief summary for
each question to explain the need or context for the question. Questions regarding
combination product issues should be grouped together.
16. Data to support discussion organized by FDA discipline and question. The level of detail
of the data should be appropriate to the meeting type requested and the stage of product
development.
IX. 	PRELIMINARY RESPONSES
Communications before the meeting between requesters and the FDA, including preliminary
responses, can serve as a foundation for discussion or as the final meeting responses.
Nevertheless, preliminary responses should not be construed as final unless there is agreement
between the requester and the FDA that additional discussion is not necessary for any question
(i.e., when the meeting is canceled because the requester is satisfied with the FDA’s preliminary
responses), or a particular question is considered resolved, allowing time for discussion of the
other questions during the meeting. Preliminary responses communicated by the FDA are not
intended to generate the submission of new information or new questions. If a requester
nonetheless provides new data or a revised or new proposal, the FDA may not be able to provide
comments on the new information, and the requester may need to submit a new meeting request
for the FDA to provide feedback on the new information.
The FDA holds internal meetings, including meetings with relevant committees within CDER or
CBER, to discuss the content of meeting packages and to gain internal alignment on the
preliminary responses. The FDA will send the requester its preliminary responses to the
questions in the meeting package no later than 5 calendar days before the in-person, virtual
(videoconference), or teleconference meeting date for BPD Type 2b and BPD Type 3 meetings.
For all other meeting types, the FDA intends to send the requester its preliminary responses to
the questions no later than 2 calendar days before the in-person, virtual (videoconference), or
teleconference meeting.
Contains Nonbinding Recommendations
16
X. 	RESCHEDULING MEETINGS
Occasionally, circumstances arise that necessitate the rescheduling of a meeting. If a meeting
needs to be rescheduled, it should be rescheduled as soon as possible after the original meeting
date. A new meeting request should not be submitted. Requesters and the FDA should take
reasonable steps to avoid rescheduling meetings. For example, if an attendee becomes
unavailable, a substitute can be identified, or comments on the topic that the attendee would have
addressed can be forwarded to the requester following the meeting. It is at the discretion of the
review division whether the meeting should be rescheduled depending on the specific
circumstances.
The following situations are examples of when the FDA may reschedule a meeting. This list
includes representative examples and is not intended to be an exhaustive list.
• 	The review team determines that additional information is needed to address the
requester’s questions or other important issues, and it is possible to identify the additional
information needed and arrange for its timely submission.
• 	Essential attendees are no longer available for the scheduled date and time because of an
unexpected or unavoidable conflict or an emergency situation.
• 	Before preliminary responses to the questions are sent by the FDA, the requester sends
the FDA additional questions or data that are intended for discussion at the meeting and
require additional review time.
• 	Attendance by additional FDA personnel not originally anticipated or requested is critical
and their unavailability precludes holding the meeting on the original date.
XI. 	CANCELING MEETINGS
Failure to pay required BPD fees for a product within the required time frame may result in the
cancellation by the FDA of a scheduled BPD meeting.24 For more information on BPD fees,
refer to the guidance for industry Assessing User Fees Under the Biosimilar User Fee
Amendments of 2022. If the requester pays the required BPD fee after the meeting has been
canceled because of nonpayment, the goal time frame for the FDA’s response to a meeting
request will be calculated from the date on which the FDA received the payment, not the date on
which the requester originally submitted the meeting request.25
Occasionally, other circumstances arise that necessitate the cancellation of a meeting. If a
meeting is canceled for reasons other than nonpayment of a required BPD fee, the FDA
24 See section 744H(a)(1)(E)(i) of the FD&C Act.
25 BsUFA III goals letter.
Contains Nonbinding Recommendations
17
considers a subsequent request to schedule a meeting to be a new request and the goal time frame
for the FDA’s response is calculated from the date of the subsequent request. Requesters and the
FDA should take reasonable steps to avoid canceling meetings (unless the meeting is no longer
necessary).
The following situations are examples of when a meeting may be canceled. This list includes
representative examples and is not intended to be an exhaustive list.
• 	The requester determines that preliminary responses to its questions are sufficient for its
needs and additional discussion is not necessary (see section IX., Preliminary Responses).
In this case, the requester should contact the FDA regulatory project manager to request
cancellation of the meeting. The FDA then considers whether it agrees that the meeting
should be canceled. Some meetings can be valuable because of the discussion they
generate and the opportunity for the division to ask about relevant matters, even if the
preliminary responses to the requester’s questions seem sufficient. If the FDA agrees that
the meeting can be canceled, the reason for cancellation is documented and the
preliminary responses represent the final responses and the official record.
• 	The FDA determines that the meeting package is inadequate or, for BPD Type 4
meetings, the meeting package is not received by the FDA within 14 calendar days of the
meeting request. Meetings are scheduled on the condition that the requester has
submitted appropriate information to support the discussion. Adequate planning by the
requester should avoid this problem.
XII. 	MEETING CONDUCT
Meetings will be chaired by an FDA staff member and begin with introductions and an overview
of the agenda. Attendees should not make audio or visual recordings of discussions at meetings
described in this guidance.
In general, presentations by requesters are not needed because the information necessary for
review and discussion should be part of the meeting package. If a requester plans to make a
presentation, the presentation should be discussed ahead of time with the FDA project manager
to determine if a presentation is warranted and to ensure that the FDA has the presentation
materials ahead of the meeting, if possible. All presentations should be kept brief to maximize
the time available for discussion. The FDA will not extend the length of a meeting to
accommodate a presentation. If a presentation contains more than a small amount of content,
distinct from clarifications or explanations of previous data, that was not included in the original
meeting package submitted for review, FDA staff may not be able to provide commentary.
Either a representative of the FDA or the requester should summarize the important discussion
points, agreements, clarifications, and action items. Summation can be done at the end of the
meeting or after the discussion of each question. Generally, the requester is asked to present the
summary to ensure that there is mutual understanding of meeting outcomes and action items.
FDA staff can add or further clarify any important points not covered in the summary and
Contains Nonbinding Recommendations
18
relevant discussion points, agreements, clarifications, and action items can be added to the
meeting minutes.
At BPD Type 4 meetings for original applications reviewed under the Program, the requester and
the FDA should also summarize agreements regarding the content of a complete application and
any agreements reached on delayed submission of certain minor application components.
XIII. 	MEETING MINUTES
Because the FDA’s minutes are the official records of meetings, the FDA’s documentation of
meeting outcomes, agreements, disagreements, and action items is critical to ensuring that this
information is preserved for meeting attendees and future reference. The FDA will issue the
official, finalized minutes to the requester within 30 calendar days after the meeting.
The following are general considerations regarding meeting minutes:
• 	FDA minutes will outline the important agreements, disagreements, issues for further
discussion, and action items from the meeting in bulleted format. This information does
not need to be in great detail. The minutes are not intended to represent a transcript of
the meeting.
• 	FDA project managers will use established templates to ensure that all important meeting
information is captured.
• 	The FDA may communicate additional information in the final minutes that was not
explicitly communicated during the meeting (e.g., PREA requirements, data standards) or
that provides further explanation of discussion topics. The FDA’s final minutes will
distinguish this additional information from the discussion that occurred during the
meeting.
• 	In cases of a WRO, the WRO will serve as the meeting minutes.
The following steps should be taken when a requester disagrees that the minutes are an accurate
account of the meeting:
1. 	The requester should contact the FDA project manager and describe the concern. If, after
contacting the FDA project manager, the requester still disagrees with the content of the
minutes, the requester should submit a description of the specific disagreements either to
the application or if there is no application, in a letter to the division director, with a copy
to the FDA project manager.
2. 	The review division and the meeting chair will take the concerns under consideration, and
the FDA will act in one of the following two ways:
Contains Nonbinding Recommendations
19
• 	If the minutes are deemed to accurately and sufficiently reflect the meeting
discussion, the FDA project manager will convey this decision to the requester and
the minutes will stand as the official documentation of the meeting.
• 	If the FDA deems it necessary, the FDA will document changes in an addendum to
the official minutes. The addendum will also document any remaining requester
objections.
XIV. 	FOLLOW-UP OPPORTUNITY
For all meeting types, to ensure the sponsor’s understanding of FDA feedback from meeting
discussions or a WRO, sponsors may submit clarifying questions to the Agency. Only questions
of a clarifying nature will be permitted (i.e., to confirm something in minutes or a WRO issued
by the FDA) rather than raising new issues or new proposals.26 The FDA intends to develop
criteria and parameters for permissible requests, and the FDA may exercise discretion about
whether requests are in scope.27 The clarifying questions should be sent in writing as a “Request
for Clarification” to the FDA within 20 calendar days following receipt of meeting minutes or a
WRO. For questions that meet the criteria, the FDA will issue a response in writing within 20
calendar days of receipt of the clarifying questions. The FDA’s response will reference the
original meeting minutes or WRO.
To request information on additional issues that were not addressed at the meeting, the requester
should submit a new meeting request or a submission containing specific questions for FDA
feedback.
