21 CFR Part 210
[Docket No. 2005N-0285]
Current Good Manufacturing Practice Regulation and
Investigational New Drugs
AGENCY: Food and Drug Administration, HHS.
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is amending its current
good manufacturing practice (CGMP) regulations for human drugs,
including biological products, to exempt most investigational ``Phase
1'' drugs from complying with the requirements in FDA's regulations.
FDA will instead exercise oversight of production of these drugs under
the agency's general statutory CGMP authority and investigational new
drug application (IND) authority. In addition, FDA is making available
simultaneously with the publication of this direct final rule, a
guidance document setting forth recommendations on approaches to CGMP
compliance for the exempted Phase 1 drugs.
Elsewhere in this issue of the Federal Register, FDA is publishing
a companion proposed rule, under FDA's usual procedure for notice-and-
comment rulemaking, to provide a procedural framework to finalize the
rule in the event the agency receives any significant adverse comments
and withdraws this direct final rule. The companion proposed rule and
direct final rule are substantively identical.
Elsewhere in this issue of the Federal Register, FDA is announcing
the availability of a draft guidance for industry entitled ``INDs--
Approaches to Complying With CGMP During Phase 1'' to provide further
guidance on the subject.
DATES: This rule is effective June 1, 2006. Submit written or
electronic comments on or before April 3, 2006. If FDA receives no
significant adverse comments within the specified comment period, the
agency will publish a document confirming the effective date of the
final rule in the Federal Register within 30 days after the comment
period on this direct final rule ends. If timely significant adverse
comments are received, the agency will publish a notice of significant
adverse comment in the Federal Register withdrawing this direct final
rule before May 2, 2006.

SUPPLEMENTARY INFORMATION:
I. Discussion
This action is intended to streamline and promote the drug
development process while ensuring the safety and quality of the
earliest stage investigational drug products, those intended for use in
Phase 1 clinical trials. Together with its companion guidance, this
rule represents a significant step in the agency's plan to formally lay
out an approach to aid manufacturers in implementing manufacturing
controls that are appropriate for this stage of development.
As defined in 21 CFR 312.21, a Phase 1 clinical trial includes the
initial introduction of an investigational new drug into humans. Such
studies are aimed at establishing basic safety and are designed to
determine the metabolism and pharmacologic actions of the drug in
humans. The total number of subjects in a Phase 1 study is limited--
generally no more than 80 subjects. This is in contrast to Phase 2 and
Phase 3 trials, which may involve substantially greater numbers of
subjects being exposed to the drug product, and which aim to test the
effectiveness of the drug product. During Phase 2 or 3, drug products
may be made available for treatment use through one of several
mechanisms for expanded access to investigational drugs.
FDA's general CGMP regulations for human drugs are set forth in
parts 210 and 211 (21 CFR parts 210 and 211). Although the preamble to
the September 1978 final rule issuing these regulations expressly
stated that the CGMP regulations applied to investigational drug
products, it also raised the possibility of proposing an additional
CGMP regulation to cover drugs being used in research:
The Commissioner finds that, as stated in Sec. 211.1, these CGMP
regulations apply to the preparation of any drug product for
administration to humans or animals, including those still in
investigational stages. It is appropriate that the process by which a
drug product is manufactured in the development phase be well
documented and controlled in order to assure the reproducibility of the
product for further testing and for ultimate commercial production. The
Commissioner is considering proposing additional CGMP regulations to
cover drugs in research stages (43 FR 45014 at 45029, September 29,
1978).
Such additional regulations have never been issued.
In 1991, the agency issued a ``Guideline on the Preparation of
Investigational New Drug Products (Human and Animal).'' That document,
however, did not discuss all manufacturing scenarios, and did not
clearly address small- or laboratory-scale production of drug products
for use in Phase 1 clinical trials. Additionally, the 1991 guidance did
not fully discuss the agency's expectations on appropriate approaches
to manufacturing controls for batches produced during drug development.
For several reasons, FDA believes that production of human drug
products, including biological drug products, intended for use in Phase
1 clinical trials should be exempted from complying with the specific
regulatory requirements set forth in parts 210 and 211. First, even if
exempted from the requirements of parts 210 and 211, investigational
drugs remain subject to the statutory requirement that deems a drug
adulterated:
if * * * the facilities or controls used for, its manufacture,
processing, packing, or holding do not conform to or are not operated
or administered in conformity with current good manufacturing practice
to assure that such drug meets the requirements of * * * [the Federal
Food, Drug, and Cosmetic] Act as to safety and has the identity and
strength, and meets the quality and purity characteristics, which it
purports or is represented to possess (21 U.S.C. 351(a)(2)(B)).
Second, FDA oversees drugs for use in Phase 1 trials through its
existing IND authority. Every IND must contain, among other things, a
section on chemistry, manufacturing, and control information that
describes the composition, manufacture, and control of the
investigational drug product (21 CFR 312.23(a)(7)). Submission of this
information, along with other information required in the IND, informs
the agency of the steps that the manufacturer is taking to ensure the
safety and quality of the investigational drug. Under this IND
authority, FDA has the option to place an IND on clinical hold if the
study subjects would be exposed to an unreasonable and significant risk
or if the IND does not contain sufficient information to assess the
risks to subjects (21 CFR 312.42). FDA also may terminate an IND if the
methods, facilities, and controls used for the manufacturing,
processing, and packing of the investigational drug are inadequate to
establish and maintain appropriate standards of identity, strength,
quality, and purity as needed for subject safety (21 CFR
312.44(b)(iii)).
Thus, even though FDA is exempting Phase 1 drug products from
compliance with the specific requirements of the CGMP regulations, the
agency retains the ability to take appropriate actions to address
manufacturing issues. For example, in addition to the authority to put
an IND on clinical hold or terminate an IND, FDA may initiate an action
to seize an investigational drug or enjoin its production if its
production does not occur under conditions sufficient to ensure the
identity, strength, quality, and purity of the drug, which may
adversely affect its safety.
FDA believes this change in the CGMP regulations (parts 210 and
211) is appropriate because many of the issues presented by the
production of investigational drugs intended for use in the relatively
small Phase 1 clinical trials are different from issues presented by
the production of drug products for use in the larger Phase 2 and Phase
3 clinical trials or for commercial marketing. We are considering
additional guidance and regulations to clarify the agency's
expectations with regard to fulfilling CMGP requirements when producing
investigational drugs for Phase 2 and Phase 3 clinical studies.
Additionally, many of the specific requirements in the regulations
in part 211 do not apply to the conditions under which many drugs for
use in Phase 1 clinical trials are produced. For example, the concerns
underlying the regulations' requirement for fully validated
manufacturing processes, rotation of the stock for drug product
containers, the repackaging and relabeling of drug products, and
separate packaging and production areas are generally not concerns for
these very limited production investigational drug products used in
Phase 1 clinical trials. Consequently, in this direct final rule, FDA
is amending the scope section of the drug CGMP regulations in 21 part
[[Page 2460]]
210 to make clear that production of investigational drugs for use in
Phase 1 studies conducted under an IND does not need to comply with the
regulations in part 211. However, once an investigational drug product
has been manufactured by, or for, a sponsor and is available for use in
a Phase 2 or Phase 3 study thus demonstrating an intent to expose more
subjects to the investigational drug and requiring that the
regulations' CGMP requirements be met, the same investigational drug
product used in any subsequent Phase 1 study by the same sponsor must
be manufactured in compliance with part 211. In addition to drug
products that, if eventually approved, would be approved under section
505 of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C.
355), this rule would apply to investigational biological products that
are subject to the CGMP requirements of section 501(a)(2)(B) of the act
(21 U.S.C. 351(a)(2)(B)). Examples of such products include recombinant
and nonrecombinant therapeutic products, vaccine products, allergenic
products, in vivo diagnostics, plasma derivative products, blood and
blood products, gene therapy products, and somatic cellular therapy
products (including xenotransplantation products) that are subject to
the CGMP requirements of section 501(a)(2)(B).
To convey the agency's current thinking on the possible approaches
to manufacturing controls for the production of Phase 1 drugs, FDA is
issuing simultaneously with this direct final rule a draft guidance
titled ``INDs--Approaches to Complying With CGMP During Phase 1,''
which sets forth recommendations on approaches to statutory compliance.
Comments on that guidance can be submitted to the public docket
identified in that document.
II. Direct Final Rulemaking
FDA has determined that the subject of this rulemaking is suitable
for a direct final rule. This direct final rule adds Sec. 210.2(c) to
make clear that production of an investigational drug for use in a
Phase 1 study conducted under an IND, when the drug has not yet been,
or is not being, manufactured for use in Phase 2 or 3 studies or for an
already approved use, is not subject to the requirements in part 211.
Additionally, the rule states that once an investigational drug product
has already been manufactured and is available for use in Phase 2 or
Phase 3 studies or for an already approved use, the investigational
drug product used in any subsequent Phase 1 investigational studies
must comply with part 211.
Because of the small batch size for these drugs, many of the issues
implicated in larger scale production, which occurs late in the drug
development process, or in commercial manufacture are not present
during production of drugs for use in Phase 1 studies. The action taken
should be noncontroversial, and the agency does not anticipate
receiving any significant adverse comment on this rule.
If FDA does not receive significant adverse comment the agency will
publish a document in the Federal Register confirming the effective
date of the final rule. The agency intends to make the direct final
rule effective 30 days after publication of the confirmation document
in the Federal Register. A significant adverse comment is one that
explains why the rule would be inappropriate, including challenges to
the rule's underlying premise or approach, or would be ineffective or
unacceptable without a change. A comment recommending a rule change in
addition to this rule will not be considered a significant adverse
comment unless the comment also states why this rule would be
ineffective without the additional change.
Elsewhere in this issue of the Federal Register, FDA is publishing
a companion proposed rule, identical in substance to the direct final
rule, that provides a procedural framework from which to proceed with
standard notice-and-comment rulemaking should the direct final rule be
withdrawn because of significant adverse comment. The comment period
for the direct final rule runs concurrently with that of the companion
proposed rule. Any comments received under the companion proposed rule
will be treated as comments regarding this direct final rule and vice
versa. FDA will not provide additional opportunity for comment on the
companion proposed rule. A full description of FDA's policy on direct
final rule procedures may be found in a guidance document published in
the Federal Register of November 21, 1997 (62 FR 62466).
III. Legal Authority
Under section 501(a)(2)(B) of the act (21 U.S.C. 201 et seq.) a
drug is deemed adulterated if the methods used in, or the facilities,
or controls used for, its manufacture, processing, packing, or holding
do not conform to or are not operated in conformity with CGMP to ensure
that such drug meets the requirements of the act as to safety, and has
the identity and strength, and meets the quality and purity
characteristics, which it purports or is represented to possess. The
rulemaking authority conferred on FDA by Congress under the act permits
the agency to amend its regulations as contemplated by this direct
final rule. Section 701(a) of the act (21 U.S.C. 371(a)) gives FDA
general rulemaking authority to issue regulations for the efficient
enforcement of the act. We refer readers to the legal authority section
of the preamble of the 1978 CGMP regulations for a fuller discussion
(43 FR 45014 at 45020-45026).
IV. Environmental Impact
The agency has determined that under 21 CFR 25.30(h) 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.
V. Analysis of Impacts
FDA has examined the impacts of the direct final rule under
Executive Order 12866 and the Regulatory Flexibility Act (5 U.S.C. 601-
612), and the Unfunded Mandates Reform Act of 1995 (Public Law 104-4).
Executive Order 12866 directs 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 agency believes that
this direct final rule is not a significant regulatory action under the
Executive order.
The Regulatory Flexibility Act requires agencies to analyze
regulatory options that would minimize any significant impact of the
rule on small entities. Because exempting production of drugs for use
in Phase 1 studies from compliance with specific regulatory
requirements does not add any burden, the agency certifies that the
rule will not have a significant economic impact on a substantial
number of small entities. Therefore, under the Regulatory Flexibility
Act, no further analysis is required.
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
[[Page 2461]]
after adjustment for inflation is $115 million using the most current
(2003) Implicit Price Deflator for the Gross Domestic Product. FDA does
not expect this final rule to result in any 1-year expenditure that
would meet or exceed this amount.
The purpose of this direct final rule is to amend our current CGMP
regulations to exempt the manufacture of Phase 1 drugs from compliance
with the regulatory requirements in part 211. The rule will affect drug
manufacturers, chemical manufacturers, and laboratories that
manufacture drugs on a small scale for use in Phase 1 clinical trials.
For drug manufacturers that produce Phase 1 drug products in-house
and also produce approved drug products, this direct final rule is
expected to reduce the amount of documentation they produce and
maintain when they manufacture a Phase 1 drug. In some cases, it should
also reduce the amount of component and product testing.
Because they have far less experience with pharmaceutical CGMPs,
some chemical manufacturers and laboratories may experience a slight
increase in documentation if they currently do not have written
standard operating procedures (SOPs), or if they need to modify
existing methods of documentation. Although formats may be different,
the rule should not require more information than is already collected
as part of standard laboratory practices.
Because the actual SOPs and manufacturing requirements are
different for each new drug product and manufacturing facility, the
procedures to comply with the statutory CGMP requirements for Phase 1
production are generated as part of product development. The savings or
costs would be incurred on a per-IND and not per-facility basis.
This rule is intended to clarify requirements of the statutory
CGMPs that are necessary for Phase 1 products and to exempt certain
drugs produced under INDs from other CGMP requirements. Some
manufacturers may realize savings because they no longer must meet
certain requirements. The savings to drug manufacturers that produce
the phase 1 drugs in-house will vary greatly from product to product.
FDA lacks data to estimate the extent of cost savings. Some examples
where substantial savings may be realized are the level of testing and
analyzing components and in-process materials. These costs can
typically range from $50 to $1,200 per component tested. The extent of
the need for SOPs and methods validation may also be greatly reduced.
We estimate that large drug manufacturers that produce Phase 1 drugs
in-house could potentially save between 24 to 40 hours per IND. In
addition, the clarifications we have made could lead some large firms
to produce future drugs for Phase 1 trials in-house, rather than
contracting the work out.
For chemical manufacturers and laboratories, the requirements in
this rule may increase the time required for developing SOPs for
quality, process, and procedural controls and will be incurred on a
recurring basis for each new product produced. There may also be an
incremental increase in training costs to educate employees on the CGMP
requirements. We estimate that an additional 12 to 24 hours may be
required for these activities depending on the experience of the entity
and its employees with our current CGMP rule.
The facility that manufactures the drug for the Phase 1 trials is
identified in the IND. We do not keep a database of these facilities
and, therefore, we do not have a precise number of entities that might
be affected by this final rule. To estimate the economic impact, we
derived an estimate of the number affected annually based on the number
of INDs we receive.
In 2003, we received about 350 research and 500 commercial INDs.
However, this rule would not apply to the majority of these INDs
because they are for drug products that already have approvals and thus
are subject to part 211. To derive an estimate of the percentage of
INDs that would be affected by this rule, we used the percentage of
total new drug applications (NDAs) that were for new molecular entities
(NMEs) and applied that percentage to the number of annual IND
applications. Historically, about 30 percent of NDAs are for NMEs each
year. Assuming the relationship would be the same for the INDs and that
the number of INDs will remain at about 850, this rule would affect
about 255 INDs per year. A firm may produce multiple drug products for
Phase 1 trials in a given year and use different companies to produce
each of these drugs. Therefore, we do not know how many individual
entities would be affected by this rule each year.
The Small Business Administration (SBA) defines manufacturers of
biologic drugs as small entities if they employ fewer than 500 people
and other drug manufacturers as small if they employ fewer than 750
people. FDA estimates that about 65 percent of the entities that submit
NDAs and biologics license applications to the agency meet SBA's
definition of a small entity. We assume that the distribution of large
to small entities that submit INDs would be about the same. Although
many of the entities that produce drug products for Phase 1 trials are
laboratories, they are usually part of much larger institutions and are
not considered small under SBA's definition. All of the entities
affected by this rule have personnel with the skills necessary to
comply with the requirements.
Because we do not know the experience levels the affected entities
have with our current CGMP requirements, we used the midpoint of the
estimated ranges to estimate the potential recurring savings or costs.
Savings to large manufacturers from reduced SOP and validation
requirements for Phase 1 drug production in-house, assuming a time
savings of 32 hours per application, a fully loaded wage rate of $45
and 90 INDs per year (approximately 35 percent of 255) would total
$129,600 per year or $1,440 per IND. This would be in addition to any
other savings from decreased component testing.
The incremental average annual cost to chemical manufacturers and
laboratories, assuming all would incur costs and assuming an average
increase of 18 hours per application for writing SOPs and training, a
fully loaded wage rate of $45, and 165 INDs (approximately 65 percent
of 255) affected per year, would total $133,650 per year or $810 per
IND.
Although we do not know the number and size distribution of the
entities affected by this rule, FDA believes that the impact on them
will be negligible and should actually reduce the compliance burden for
some. To clarify the requirements for the manufacture of drugs for
Phase 1 trials, we have prepared a draft guidance document with
recommendations for compliance.
VI. Paperwork Reduction Act of 1995
This direct final rule contains no new information collection
requirements that are subject to review by the Office of Management and
Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520). Under the direct final rule, the production of human drug
products, including biological drug products, intended for use in Phase
1 clinical trials will be exempted from complying with the specific
regulatory requirements set forth in parts 210 and 211. Parts 210 and
211 contain information collection requirements that have been approved
by OMB under control number 0910-0139. As explained in the following
paragraph, the information collection requirements
[[Page 2462]]
in parts 210 and 211 will be reduced under this direct final rule.
The OMB-approved hourly burden to comply with the information
collection requirements in parts 210 and 211 (control number 0910-0139)
is 848,625 hours. FDA estimates that, under the direct final rule,
approximately 7,315 drugs will be exempted from complying with the
specific regulatory requirements set forth in parts 210 and 211. Based
on this number and the total number of drugs that are subject to parts
210 and 211, FDA estimates that the burden hours approved under control
number 0910-0139 will be reduced by approximately 50,493 hours. Thus,
as a result of the direct final rule, the amended burden hours in
control number 0910-0139 will be approximately 798,132 hours.
VII. Federalism
FDA has analyzed this direct final rule in accordance with the
principles set forth in Executive Order 13132. FDA has determined that
the rule does not contain policies that 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 has concluded
that the 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.
