Quality Considerations for Continuous Manufacturing; Draft 
Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

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

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a draft guidance for industry entitled ``Quality 
Considerations for Continuous Manufacturing.'' This draft guidance 
provides information regarding FDA's current thinking on the quality 
considerations for continuous manufacturing of small molecule, solid 
oral drug products that are regulated by the Center for Drug Evaluation 
and Research (CDER). The draft guidance describes several key quality 
considerations and provides recommendations for how applicants should 
address these considerations in new drug applications (NDAs), 
abbreviated new drug applications (ANDAs), and supplemental NDAs and 
ANDAs, for small molecule, solid oral drug products that are produced 
via a continuous manufacturing process. FDA supports the development 
and implementation of continuous manufacturing for drug substances and 
all finished dosage forms where appropriate, including those submitted 
in NDAs, ANDAs, drug master files, biologics license applications 
(BLAs), and nonapplication over the counter products. Scientific 
principles described in this draft guidance may also be applicable to 
continuous manufacturing technologies used for these drugs. However, 
this draft guidance is not intended to provide recommendations specific 
to continuous manufacturing technologies used for biological products 
under a BLA.

DATES: Submit either electronic or written comments on the draft 
guidance by May 28, 2019 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

ADDRESSES: You may submit comments on any guidance at any time as 
follows:

you claim to be confidential with a heading or cover note that states 
``THIS DOCUMENT CONTAINS CONFIDENTIAL INFORMATION.'' The Agency will 
review this copy, including the claimed confidential information, in 
its consideration of comments. The second copy, which will have the 
claimed confidential information redacted/blacked out, will be 
available for public viewing and posted on https://www.regulations.gov. 
Submit both copies to the Dockets Management Staff. If you do not wish

SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Quality Considerations for Continuous Manufacturing.'' The 
draft guidance was prepared by CDER's Office of Pharmaceutical Quality, 
which is committed to supporting and enabling pharmaceutical innovation 
and modernization as part of the Agency's mission to protect and 
promote public health. While the implementation of emerging technology, 
such as continuous manufacturing, is critical to modernizing 
pharmaceutical manufacturing and improving quality, FDA also recognizes 
that innovative approaches to manufacturing may represent challenges to 
industry and regulators. By the very nature of an approach being 
innovative, a limited knowledge and experiential base about the 
technology may exist. Pharmaceutical companies may have concerns that 
using continuous manufacturing could result in delays while FDA 
reviewers and investigators familiarize themselves with the new 
technologies and determine how they fit within existing regulatory 
approaches.
    This draft guidance provides information regarding FDA's current 
thinking on the quality considerations for continuous manufacturing of 
small molecule, solid oral drug products that are regulated by CDER. 
The draft guidance describes several key quality considerations and 
provides recommendations for how applicants should address these 
considerations in NDAs, ANDAs, and supplemental NDAs and ANDAs, for 
small molecule, solid oral drug products that are produced via a 
continuous manufacturing process.
    The draft guidance takes into account the comments that were 
submitted to Docket No. FDA-2017-N-2697 (``Submission of Proposed 
Recommendations for Industry on Developing Continuous Manufacturing of 
Solid Dosage Drug Products in Pharmaceutical Manufacturing; 
Establishment of Public Docket''). FDA invites general comments on the 
quality considerations described in the draft guidance, including 
comments on control strategy, facility, and process validation 
considerations for continuous manufacturing of small molecule, solid 
oral drug products.
    In addition to this draft guidance, pharmaceutical manufacturers 
with product-specific continuous manufacturing questions may submit a 
proposal to the Emerging Technology program. Refer to FDA guidance for 
industry, ``Advancement of Emerging Technology Applications for 
Pharmaceutical Innovation and Modernization'' (September 2017) at 
https://www.fda.gov/ucm/groups/fdagov-public/@fdagov-drugs-gen/documents/document/ucm478821.pdf.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the current thinking of FDA on ``Quality 
Considerations for Continuous Manufacturing.'' 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. This guidance is not subject to 
Executive Order 12866.

II. Additional Issues for Consideration

    In addition to comments on the draft guidance generally, FDA is 
requesting comments and related supporting information on the following 
topics: (1) Data storage and handling from process analytical 
technology systems, (2) potential approaches for situations where 
direct attribute measurement is not possible (e.g., low-dose 
compounds), (3) contract manufacturers employing continuous 
manufacturing, (4) risk-based reporting of routine model maintenance 
and updates, and (5) statistical approaches using large samples (e.g., 
Large N). FDA is seeking public comment on topics for potential 
inclusion in the final guidance or additional guidance and any other 
alternative approaches.

III. Paperwork Reduction Act of 1995

    This draft guidance contains information collection provisions that 
are subject to review by the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3520). 
The collections of information in 21 CFR parts 210-211 have been 
approved under OMB control number 0910-0139. The submission of INDs 
under 21 CFR 312.23 is approved by OMB control

[[Page 6405]]

number 0910-0014. The submission of BLAs under 21 CFR 601.2 and 601.12 
is approved by OMB control number 0910-0338. The submission of NDAs and 
ANDAs under 21 CFR 314.50, 314.70, 314.71, 314.94, and 314.97 is 
approved by OMB control number 0910-0001. The information to be 
included in a meeting request for a product submitted in an IND, BLA, 
or NDA is approved by OMB control number 0910-0429 (``Guidance for 
Industry on Formal Meetings Between the FDA and Sponsors or 
Applicants'' (December 2017)). Information to be included in a meeting 
request for a product submitted in an ANDA is approved by OMB control 
number 0910-0797 (``Guidance on Controlled Correspondence Related to 
Generic Drug Development'' (December 2015)).
