QbD: new Guidance from EMA and FDA
The European Medicine Agency (EMA) and the U.S. Food and Drug Agency (FDA) have published a joint question-and-answer document that provides further guidance on the quality-by-design concept. Read more.
http://www.gmp-compliance.org/ecanl_654_0_news_4015_8280,8356,Z-PDM_n.html
The Quality by Design (QbD) concept has been introduced by the International Conference on Harmonisation (ICH) document Q8, supported by Q9, Q10 and also Q11. In the meantime it is well-known within the pharmaceutical industry. However many companies still struggle with the implementation. Both the European Medicine Agency (EMA) and the U.S. Food and Drug Agency (FDA) are supporting the pharmaceutical industry in the employment of the paradigm. Now, EMA and FDA have published a second joint question-and-answer document that provides further guidance on the quality-by-design concept.
The new document focuses on ‘design space verification’ and reflects conclusions reached in the on-going parallel assessment, which was launched in 2011. The objective of the parallel assessment is to share knowledge, facilitate a consistent implementation of the international guidelines on the implementation of the quality-by-design concept and promote the availability of medicines of consistent quality throughout the European Union (EU) and the USA.
The EMA and the US FDA will publish further conclusions on other quality-by-design-related topics as the pilot programme continues and more parallel assessments are conducted.

The European Medicines Agency (EMA) and the United States Food and Drug Administration
(US FDA) have published a second joint question-and-answer document that provides guidance on the quality-by-design concept.
Quality-by-design is a science and risk-based approach to pharmaceutical development and manufacturing. It involves designing and developing pharmaceutical formulations and manufacturing processes to help ensure product quality; these concepts are described in the international guidelines ICH Q8, Q9, Q10 and Q11.
The document published today focuses on ‘design space verification’, a demonstration that the combination of the process parameters and material attributes established at pilot scale during pharmaceutical development are capable of delivering a product of appropriate quality on a commercial scale.
In March 2011, the EMA and US FDA launched a three-year pilot programme for the parallel assessment of certain quality or chemistry manufacturing and control (CMC) sections of applications that are relevant to quality-by-design. With the agreement of the applicants, experts from the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) participate as observers in the programme.
The objective of the parallel assessment is to share knowledge, facilitate a consistent implementation of the international guidelines on the implementation of the quality-by-design concept and promote the availability of medicines of consistent quality throughout the European Union (EU) and the USA.
The question-and-answer document published today reflects the conclusions reached by the EU and US regulators on the specific topic of design space verification as part of their parallel assessment.
The EMA and the US FDA will publish further conclusions on other quality-by-design-related topics as the pilot programme continues and more parallel assessments are conducted.
The pilot programme is open to selected procedures, including applications for initial marketing authorisations, type-II variations and scientific advice. Participation in the pilot is voluntary. Interested applicants and sponsors should notify both agencies three months prior to submission of an application.

methodology provides a risk-based approach to residual solvent
analysis that considers a patient’s exposure to a solvent residue
in the drug product. Solvents have been classified based on their
potential health risks into three main classes:
1. Class 1: Solvents should not be used because of the
unacceptable toxicities or deleterious environmental effects.
2. Class 2: Solvents should be limited because of inherent
toxicities.
3. Class 3: Solvents may be regarded as less toxic and of lower
risk to human health.
Testing is only required for those solvents used in the
manufacturing or purification process of drug substances, excipients
or products. This allows each company to determine which solvents
it uses in production and develop testing procedures that address
their specific needs. It is the responsibility of the drug manufacturer
to qualify the purity of all the components used in the manufacturing
of the drug product. This would pertain to items such as excipients,
of which some contain residual levels of Class 1 solvents by nature
of the manufacturing process and/or nature of the starting materials
(e.g. ethyl cellulose). The new 467 monograph provides an optional
method to determine when residual solvent testing is required for
Class 2 solvents. Each Class 2 solvent is assigned a permitted daily
exposure (PDE) limit, which is the pharmaceutically acceptable
intake level of a residual solvent.
The USP has provided a method for the identification, control,
and quantification of Class 1 and 2 residual solvents. The method
calls for a gas chromatographic (GC) analysis with flame ionization
detection (FID) and a headspace injection from either water or
organic diluent. The monograph has suggested two procedures:
Procedure A G43 (Zebron ZB-624) phase and Procedure B G16
(Zebron ZB-WAXplus) phase. Procedure A should be used first. If
a compound is determined to be above the specified concentration
limit, then Procedure B should be used to confirm its identity.
Since there are known co-elutions on both phases, the orthogonal
selectivity ensures that co-elutions on one phase will be resolved
on the other. Neither procedure is quantitative, so to determine
the concentration the monograph specifies Procedure C, which
utilizes whichever phase will give the fewest co-elutions. Class
3 solvents may be determined by 731-Loss on Drying unless the
level is expected to be >5000 ppm or 50 mg. If the loss on drying
is >0.5 %, then a water deterrmination should be performed using
921-Water Determination.
One of the most important considerations is that, once
implemented, the new method will pertain to all currently marketed
drug products as well as those in development and clinical trials8
United States Pharmacopoeia (USP):
In 1988, the United States Pharmacopoeia (USP) provided
control limits and testing criteria for seven organic volatile impurities
(OVIs) under official monograph 4678
. According to USP, testing
should be conducted only if a manufacturer has indicated the
possible presence of a solvent in a product. Testing may be avoided
when a manufacturer has assurance, based on the knowledge of
the manufacturing process and controlled handling, shipping, and
storage of the product, that no potential exists for specific solvents
to be present and that the product, if tested, will comply with the
accepted limit. Items shipped in airtight containers (such as those
used for food additives) can be considered not to have acquired
any solvents during transportation2
.
The compounds are chosen based on relative toxicity and only
applied to drug substances and some excipients8
. In addition, a
test for ethylene oxide is conducted if specified in the individual
monograph. Unless otherwise specified in the individual monograph,
the acceptable limit for ethylene oxide is 10 ppm. USP does not
address all other solvents mentioned in the ICH guideline2
.
In an effort to harmonize with the International Conference
for Harmonization (ICH), the USP has proposed the adoption of
a slightly modified version of ICH (Q3C) methodology, which has
been scheduled for implementation on July 1, 2007. The ICH Q3C
Organic Volatile Impurities
Of the solvents targeted in USP 26 General Chapter 467, only
methylene chloride may appear in bulk pharmaceutical products
manufactured by Pfizer at the Kalamazoo plant. For those products
where OVI testing is required, our material will meet the compendial
limits for methylene chloride and other solvents that may be added
to the target list in the future.
No OVI requirement exists in the USP 26 monograph
for Triamcinolone, but Triamcinolone from Pfizer meets the
requirements of USP 26 General Chapter 467.
Introduction
Residual solvents in pharmaceuticals, commonly known as
organic volatile impurities (OVIs), are chemicals that are either
used or produced during the manufacture of active pharmaceutical
ingredients (APIs), excipients and drug products1, 2
.
Organic solvents play an essential role in drug-substance and
excipient manufacture (e.g., reaction, separation and purification)
and in drug-product formulation (e.g., granulation and coating) 3
.
Some organic solvents are often used during the synthesis of active
pharmaceutical ingredients and excipients or during the preparation
of drug products to enhance the yield, increase solubility or aid
crystallization2
. These process solvents cannot be completely
removed by practical manufacturing practices such as freeze–drying
and drying at high temperature under vacuum. Therefore, some
residual solvents may remain in drug substance material4
. Typically,
the final purification step in many pharmaceutical drug-substance
processes involves a crystallization step, and the crystals thus
formed can entrap a finite amount of solvent from the mother liquor
that may cause degradation of the drug, OVIs may also contaminate
the products during packaging, storage in warehouses and/or during
transportation3
.
While solvents play a key role in the production of
pharmaceuticals, there is also a downside, as many of the
solvents used have toxic or environmentally hazardous properties.
Complete removal of residual levels of solvents is impractical from a
manufacturing standpoint, so it is inevitable that traces will remain inthe final product. The presence of these unwanted chemicals even
in small amounts may influence the efficacy, safety and stability of
the pharmaceutical products. Because residual solvents have no
therapeutic benefits but may be hazardous to human health and
the environment, it must be ensured that they are either not present
in products or are only present below recommended acceptable
levels. It is a drug manufacturer’s responsibility to ensure that any
OVIs present in the final product are not harmful to humans and
that medicinal products do not contain levels of residual solvents
higher than recommended safety limits. Solvents known to cause
unacceptable toxicity should be avoided unless their use can be
justified on the basis of a risk-benefit assessment2
. Because of their
proven or potential toxicity, the level of residual solvents is controlled
through national and international guidelines, for example, through
the FDA and International Conference on Harmonization.
“All drug substances, excipients, and products are subject to
relevant control of residual solvents, even when no test is specified
in the individual monograph.”
Regulatory and Compliance Environment
One of the essential aspects of pharmaceutical manufacturing
is regulatory compliance, which typically encompasses two aspects.
The first is compliance with private sets of standards based on
an applicant filing with a regulatory agency, which requires the
applicant to report the determined residual solvent levels in a
number of representative batches of pharmaceutical product to
establish typical levels of solvent contamination that can routinely
be achieved. Based on a statistical evaluation of the reported
data, a specification is agreed for solvents used in the final step of
the process and a decision made on whether testing is required
for solvent used at earlier stages in the process. To arrive at a
specification that is a measure of the routine performance of the
process, regulatory agencies require numerical data rather than
reporting compliance with a limit test.
Internationally, there has been a need to establish regulatory
standard guidelines. In 1997, The International Conference on
Harmonization of Technical Requirements for Registration of
Pharmaceuticals for Human Use (ICH), through its Q3C Expert
working group formed by regulators from the three ICH regions,
industry representatives and interested parties/observers, finalized
the Q3C guideline on residual solvents. Essentially, ICH has
consistently proposed that limits on organic solvents be set at levels
that can be justified by existing safety and toxicity data, and also kept
proposed limits within the level achievable by normal manufacturing
processes and within current analytic capabilities.
The second aspect is compliance with public standards set
by Pharmacopoeias from the three ICH regions (United States
Pharmacopoeia (USP), European Pharmacopoeia (Ph. Eur.) and
Japanese Pharmacopoeia (JP)) and also with local pharmacopoeias
from countries outside the ICH regions. In the recent past, guidelines
for organic residual solvents for public standards have generally
been vague and not up-to-date. The pharmacopoeial approach
was typically a limit test for residual solvents, employing standard
addition3
. The USP set the official limits in USP 23rd edition in the
general chapter 467, Organic Volatile Impurities5
. Very early on,
the Ph. Eur. employed the ICH Q3C regulatory approach and
updated the acceptance limits but kept the methodology as a limit
test based on standard addition. The general method in Ph. Eur. for
Identification and Control of Residual Solvents in drug substances
defines a general procedure and describes two complementary gas
chromatography (GC) conditions for identifying unknown solvents.
‘‘System A’’ is recommended for general use and is equivalent
to ‘‘Methods IV and V’’ of the USP for analysis of volatile organic
impurities ‘‘System B’’ is used to confirm identification and to solve
co-elutions. Implementation of this general method is a subject of
debate in the pharmaceutical industry due to its limited selectivity
and sensitivity3
. Historically, until its 27th edition, the USP restricted
its listing of residual solvents to those of Class 1 and neglected to
consider the wide range of organic solvents used routinely in the
pharmaceutical industry. Furthermore, the limits stated for Class 1
solvents like benzene, chloroform, 1, 4-dioxane, methylene chloride,
and 1, 1, 1-trichloroethane are in the range 2–600 (ppm) and are
therefore not in concordance with the ICH guideline. Residual
solvent testing using GC has been included in the pharmacopeias
for almost 20 years, while residual solvent-test methods have
been reported in the literature since before that. With USP 28, the
public standard for residual solvents was updated to comply with
the ICH Q3C guideline, but the methodology (the same limit-test
approach as Ph. Eur.) and the targeted monographs were not
considered appropriate by industry and regulators, leading to a
notice postponing implementation in USP 296
.
ICh Guideline
The objective of this guidance is to recommend acceptable
amounts for residual solvents in pharmaceuticals for the safety of
the patient. The guidance recommends use of less toxic solvents
and describes levels considered to be toxicologically acceptable
for some residual solvents.
Residual solvents in pharmaceuticals are defined here as
‘organic volatile chemicals that are used or produced in the
manufacture of drug substances or excipients, or in the preparation
of drug products’. This guidance does not address solvents
deliberately used as excipients nor does it address solvates.
However, the content of solvents in such products should be
evaluated and justified.
Since there is no therapeutic benefit from residual solvents,
all residual solvents should be removed to the extent possible to
meet product specifications, good manufacturing practices, or other
quality-based requirements. Drug products should contain no higher
levels of residual solvents than can be supported by safety data.
Some solvents that are known to cause unacceptable toxicities
(Class 1) should be avoided in the production of drug substances,
excipients, or drug products unless their use can be strongly justified
in a risk-benefit assessment. Some solvents associated with less
severe toxicity (Class 2) should be limited in order to protect patients
from potential adverse effects. Ideally, less toxic solvents (Class 3)
should be used where practical7
Scope of the Guidance
Residual solvents in drug substances, excipients, and drug
products are within the scope of this guidance. Therefore, testing
should be performed for residual solvents when production or
purification processes are known to result in the presence of such
solvents. It is only necessary to test for solvents that are used or
produced in the manufacture or purification of drug substances,
excipients, or drug products. Although manufacturers may choose
to test the drug product, a cumulative method may be used to
calculate the residual solvent levels in the drug product from the
levels in the ingredients used to produce the drug product. If the
calculation results in a level equal to or below that recommended
in this guidance, no testing of the drug product for residual solvents
need be considered. If, however, the calculated level is above the
recommended level, the drug product should be tested to ascertain
whether the formulation process has reduced the relevant solvent
level to within the acceptable amount. Drug product should also be
tested if a solvent is used during its manufacture.
This guidance does not apply to potential new drug substances,
excipients, or drug products used during the clinical research
stages of development, nor does it apply to existing marketed
drug products. The guidance applies to all dosage forms androutes of administration. Higher levels of residual solvents may be
acceptable in certain cases such as short-term (30 days or less)
or topical application. Justification for these levels should be made
on a case-by-case basis7
.
Classification of Residual Solvents
OVIs are classified into three classes on the basis of their
toxicity level and the degree to which they can be considered
an environmental hazard. The list provided in the guideline is
not exhaustive, and one should evaluate the synthesis and
manufacturing processes for all possible residual solvents.
The term, tolerable daily intake (TDI), is used by the International
Program on Chemical Safety (IPCS) to describe exposure limits
of toxic chemicals and the term, acceptable daily intake (ADI), is
used by the World Health Organization (WHO) and other national
and international health authorities and institutes. The new term,
permitted daily exposure (PDE), is defined in the present guidance
as a pharmaceutically acceptable intake of residual solvents to avoid
confusion of differing values for ADI’s of the same substance7
.
Residual solvents are classified on the basis
of risk assessment:
1. Class 1 solvents (Solvents to be avoided): Known human
carcinogens, strongly suspected human carcinogens, and
environmental hazards.
2. Class 2 solvents (Solvents to be limited): Non-genotoxic
animal carcinogens or possible causative agents of other
irreversible toxicity such as neurotoxicity or teratogenicity.3. Class 3 solvents (Solvents with low toxic potential): Solvents
with low toxic potential to man; no health-based exposure limit
is needed. Class 3 solvents have PDE’s of 50 milligrams (mg)
or more per day.
4. Class 4 solvents (Solvents for which no adequate
toxicological data was found): No adequate toxicological
data on which to base a PDE (permitted dose exposure) was
found.
Environmental Regulation of Organic Volatile
Solvents
Several of the residual solvents frequently used in the
production of pharmaceuticals are listed as toxic chemicals in
Environmental Health Criteria (EHC) monographs and in the
Integrated Risk Information System (IRIS). The objectives of such
groups as the International Programme on Chemical Safety (IPCS),
the U.S. Environmental Protection Agency (EPA), and the U.S.
Food and Drug Administration (FDA) include the determination
of acceptable exposure levels. The goal is protection of human
health and maintenance of environmental integrity against the
possible deleterious effects of chemicals resulting from long-term
environmental exposure. The methods involved in the estimation
of maximum safe exposure limits are usually based on long-term
studies. When long-term study data are unavailable, shorter term
study data can be used with modification of the approach such as
use of larger safety factors. The approach described therein relates
primarily to long-term or lifetime exposure of the general population
in the ambient environment (i.e., ambient air, food, drinking water,
and other media) 7
.
Limits of Residual Solvents
Solvents to Be Avoided: Solvents in Class 1 (Table 1) should
not be employed in the manufacture of drug substances, excipients,and drug products because of their unacceptable toxicity or their
deleterious environmental effect. However, if their use is unavoidable
in order to produce a drug product with a significant therapeutic
advance, then their levels should be restricted as shown in Table
1, unless otherwise justified. The solvent 1, 1, 1-Trichloroethane
is included in Table 1 because it is an environmental hazard. The
stated limit of 1,500 ppm is based on a review of the safety data
Analysis of Residual Solvent in
Pharmaceuticals
The analysis of residual solvents is an essential part in the
quality control of drug substances used in preclinical or clinical
trials as well as for use in commercial drug products. Residual
solvent analysis of bulk drug substance and finished pharmaceutical
products is necessary for a number of reasons such as –
1. High levels of residual organic solvents represent a risk to human
health because of their toxicity.
2. Residual organic solvents also play a role in the physicochemical
properties of the bulk drug substance. Crystalline nature of the
bulk drug substance can be affected. Differences in the crystal
structure of the bulk drug may lead to changes in dissolution
properties and problems with formulation of the finished
product.
3. Finally, residual organic solvents can create odor problems
and color changes in the finished product and, thus, can lead
to consumer complaints.
4. Often, the main purpose for residual solvent testing is in its use
as a monitoring check for further drying of bulk pharmaceuticals
or as a final check of a finished product.
5. Testing for solvent content in intermediates may need to be
performed if a critical amount of residual solvent(s) remaining
in the intermediate can alter the next step of the process.
6. Knowledge of the solvent content in the starting materials may
help to the development chemist to understand the synthetic
routes and predict potential process related impurities.
7. Knowing the solvents used in the process allows the development
chemist to look for possible compound- solvent interactions
which can lead to the formation of impurities5, 16
.
Residual solvent analysis can be performed with a large array of
analytical techniques17. The most popular, and the most appropriate,
specific solvent analysis is testing by gas chromatography (GC).
Modern capillary-column gas chromatographs can separate a large
number of volatile components, permitting identification through
retention characteristics and detection at ppm levels using a broad
range of detectors5
.Gas chromatographic testing can be categorized
into three main procedures according to the means of introducing
the sample into the instrument. A direct gas chromatographic
procedure is one in which a portion of the actual drug substance
or formulation is injected into a GC system. The drug substance
is usually dissolved in an appropriate solvent and loaded into a
syringe and injected. Headspace analysis, on the other hand, is
an indirect testing procedure. The analysis is conducted when a
volume of gas above the drug substance or formulation is collected
and analyzed by a gas chromatograph. Finally, solid-phase microextraction (SPME) is making much progress in recent years for
residual solvent testing. In SPME, a silica fiber coated with a sorbent
is used to collect and concentrate the volatile solvents. The volatiles
are then thermally desorbed in the inlet of the gas chromatograph
and analyzed18
.
Many alternatives to gas chromatography have been used to
determine the level of residual solvent in pharmaceutical products.
Many of these procedures are either nonspecific—that is, the
solvents are not identified—or they have high detection limits, so
they are inappropriate for the detailed product characterization
required for a regulatory submission. The oldest and simplest
method for determining the quantity of volatile residue is measuring
the weight loss of a sample during heating. LOD method is widely
used, particularly for Class 3 solvents, due to its simplicity and
ease of introduction into even the most basic analytical laboratory5
.
Another approach is to use thermogravimetric analysis (TGA),
which is a well-known method for the quantitative analysis of the
loss of volatile components from a sample18. Spectroscopic and
spectrometric methods have generally lacked the low detection
limits needed for toxic residual solvents, although the detection limits
would be applicable for ICH class 2 and 3 solvents. In the case of
Infrared Spectroscopy (IR), a detection limit above 100 ppm and
lack of accuracy at low concentrations of residual solvent has been
reported. For NMR also high detection limit has been reported5
.
CONCLUSION
Whenever organic solvents are used in the production of
pharmaceutical products, especially in the last processing steps,
the content of residual solvent in the final product should be
analyzed. The complete removal of residual level of these solvents
is impracticable and traces always remain in the final products.
The presence of these residual solvents even in small amounts
has a negative influence not only on the quality of products but
also on human health. Acceptability of residual solvents seems to
be best judged following the ICH residual solvent guideline which
is adopted by the USP, EP and JP; it classifies the solvent into
four groups. In class 1 are included the most toxic solvents which,
unless strongly justified, should be avoided. For the toxic solvents
of class 2, the limits are expressed as concentrations (ppm) and
additionally in the case of known daily drug intake, by the very
important ‘permitted daily exposure’ (PDE). The class 3 includes
the solvents with low toxic potential for which the general limit is
set at 0.5%. The class 4 includes solvents for which no adequate
toxicological data was found.

How much does quality cost? Most companies would be hard-pressed to translate “quality” into dollars and cents. What they realize, however, is that a lack of quality could cost millions of dollars in rework, scrap, recall, or even liability lawsuits.
This is especially true in the strict FDA and ISO environments, where quality is closely incorporated in regulations and standards. The FDA explicitly states that the overarching philosophy of the Current Good Manufacturing Practice (CGMP) Regulations is this: Quality should be built into the product, and testing alone cannot be relied to ensure product quality. Similarly, the eight quality management principles that form the basis of the ISO 9000 series of standards articulate the importance of making quality an integral part of a manufacturer’s daily operations.
Six Ways for Optimization
This white paper posits that an optimal quality management system is the foundation for long-term regulatory compliance, and consequently, for enduring market success. Without a solid quality infrastructure, your organization is simply not equipped to face the challenges of the regulatory environment and the vicissitudes of a competitive market. In addition, an optimal system will spare you the unnecessary, and often staggering, cost of poor quality.
MasterControl Inc., a leading provider of quality management software solutions for companies in the FDA and ISO sectors, offers the following tips for optimizing your quality management system to ensure high-quality products/services and continuous compliance.
