Events Leading to Formation of
FDA
1905 - Samuel Hopkins Adams :11 articles The Great American Fraud in
Collier's Weekly.
– analyzed the contents of some of the country's most popular medicines.
– argued that many of the companies producing these medicines were
making false claims about their products.
– some cases, these medicines were actually damaging the health of
those people using them
1906 - Upton Sinclair: The Jungle
– fictional portrait of life and death of working class immigrates in turn-ofthe-century Chicago
– filled with page after page of nauseating detail he had researched about
the meat-packing industry
Public demanded sweeping reforms in the food industry
30 June 1906 President Roosevelt signed the Food and Drugs Act, known
simply as the Wiley Act.

1906 Food and Drugs Act
• Prohibited interstate transport of unlawful food and drugs
under penalty of seizure of the questionable products
and/or prosecution of the responsible parties
• Basis on regulation of product labeling rather than premarket approval
• Drugs, defined in accordance with the standards of
strength, quality, and purity in the United States
Pharmacopoeia and the National Formulary, could not
be sold in any other condition unless the specific
variations from the applicable standards were plainly
stated on the label

1906 Food and Drugs Act
• Foods were not defined according to analogous
standards, but the law prohibited the addition of any
ingredients that would substitute for the food, conceal
damage, pose a health hazard, or constitute a filthy or
decomposed substance
• If the manufacturer opted to list the weight or measure of
a food, this had to be done accurately
• The food or drug label could not be false or misleading in
any particular, and the presence and amount of eleven
dangerous ingredients, including alcohol, heroin, and
cocaine, had to be listed

Drug Development and Approval
Process
• U.S. system most rigorous in the world
• On average, it costs a company $360 million to get one new
medicine from the laboratory to the pharmacist's shelf
• It takes 12 years on average for an experimental drug to travel from
lab to medicine chest.
• Only five in 5,000 compounds that enter preclinical testing make it to
human testing.
• One of these five tested in people is approved.
PharmaSys, Inc.
www.pharma-sys.com
24
Biological Screening and
Pharmacological Testing
• Studies to explore the pharmacological
activity and therapeutic potential of
compounds.
– animals, isolated cell cultures and tissues,
enzymes and cloned receptor sites as well as
computer models.

26
Toxicology and Safety Testing
• Tests to determine the potential risk a
compound poses to man and the
environment
– These studies involve the use of animals,
tissue cultures, and other test systems to
examine the relationship between factors
such as dose level, frequency of
administration, and duration of exposure to
both the short- and long-term survival of living
organisms.

monitored by the FDA to protect and ensure the safety of participants in
medical research.
An IRB must be composed of no less than five experts and lay people with
varying backgrounds to ensure a complete and adequate review of activities
commonly conducted by research institutions.
In addition to possessing the professional competence needed to review
specific activities, an IRB must be able to ascertain the acceptability of
applications and proposals in terms of institutional commitments and
regulations, applicable law, standards of professional conduct and practice,
and community attitudes.
Therefore, IRBs must be composed of people whose concerns are in
relevant areas.

beginning of human testing and just prior to marketing to
show that the formulation used to demonstrate safety
and efficacy in clinical trials is equivalent to the product
that will be distributed for sale.
• Companies also conduct bioavailability studies on
marketed products whenever they change the method
used to administer the drug (e.g., from injection or oral
dose form), the composition of the drug, the
concentration of the active ingredient, or the
manufacturing process used to produce the drug.

74
§ 820.30(h) Design Transfer
• Each manufacturer shall establish and maintain
procedures to ensure that the device design is
correctly translated into production
specifications.
– Production specifications must ensure that
manufactured devices are repeatedly and reliably
produced within product and process capabilities.
– The process of encapsulating knowledge about the
device into production specifications is critical to
device quality.
PharmaSys, Inc.
www.pharma-sys.com
75
§ 820.30(j) Design history file
• Each manufacturer shall establish and maintain
a DHF for each type of device.
– Other national regulations require some form of
documentation and records. Product documentation
required by Canada, Europe, and Japan contain
certain elements of the U. S. FDA design history file
requirements without requiring all the elements to be
compiled in a file.
– Virtually every section of the design control
requirements specifies information which should be
recorded. The compilation of these records is
sometimes referred to as the design history file.
PharmaSys, Inc.
www.pharma-sys.com
76
Typical DHF
• Detailed design and development plan
specifying design tasks and deliverables.
• Copies of approved design input
documents and design output documents.
• Documentation of design reviews.
• Validation documentation.
• When applicable, copies of controlled
design documents and change control
records.
PharmaSys, Inc.
www.pharma-sys.com
77
Design changes
• establish and maintain procedures for
design changes before their
implementation.
– Document control
– Change control
PharmaSys, Inc.

78
Production Testing is not
Verification
• Some manufacturers erroneously equate production
testing with verification.
– Verification testing establishes conformance of design output
with design input
– Production testing is to determine whether the unit under test
has been correctly manufactured… screen out manufacturing
process errors and detect infant mortality failures
• Typically, a small subset of functional and performance
tests accomplish this objective with a high degree of
accuracy.
• Production testing is rarely, if ever, comprehensive
enough to verify the design.
PharmaSys, Inc.
www.pharma-sys.com
79
Example
A leakage test may be used during production to
ensure that a hermetically-sealed enclosure was
properly assembled … may not be sensitive
enough to detect long-term diffusion of gas
through the packaging material.
Permeability of the packaging material is an
intrinsic property of the material rather than an
assembly issue… likely be verified using a more
specialized test than is used during production.
PharmaSys, Inc.
www.pharma-sys.com
80
Environmental Conditions
• Validation should include simulation of the
expected environmental conditions
PharmaSys, Inc.
www.pharma-sys.com
81
VALIDATION DOCUMENTATION
• Validation is a compilation of the results of all
validation activities.
• For a complex design, the detailed results may
be contained in a variety of separate documents
and summarized in a validation report.
• Supporting test articles should be explicitly
referenced in the validation report and either
included as an appendix or available in the
design history file.
PharmaSys, Inc.
www.pharma-sys.com
82
WHAT PROCESSES SHOULD BE
VALIDATED
• Routine end-product tests have insufficient
sensitivity to verify the desired safety and
efficacy of the finished devices
• Clinical or destructive testing would be required
to show that the manufacturing process has
produced the desired result or product
• Routine end-product tests do not reveal all
variations in safety and efficacy that may occur
in the finished devices.
• The process capability is unknown, or it is
suspected that the process is barely capable of
meeting the device specifications.

§ 820.75 PROCESS VALIDATION
•
(a) Where the results of a process cannot be fully verified by subsequent
inspection and test, the process shall be validated with a high degree of
assurance and approved according to established procedures.
– The validation activities and results, including the date and signature of the
individual(s) approving the validation and where appropriate the major equipment
validated, shall be documented.
•
(b) Each manufacturer shall establish and maintain procedures for
monitoring and control of process parameters for validated processes to
ensure that the specified requirements continue to be met.
– (1) Each manufacturer shall ensure that validated processes are performed by
qualified individual(s).
– (2) For validated processes, the monitoring and control methods and data, the
date performed, and, where appropriate, the individual(s) performing the process
or the major equipment used shall be documented.
•
(c) When changes or process deviations occur, the manufacturer shall
review and evaluate the process and perform revalidation where
appropriate. These activities shall be documented.

Planning the Process Validation
Study
• The plan should include design reviews.
• The plan for the validation study is documented
in the validation protocol.
• A copy of the protocol and validation results are
placed in the Design History File (DHF) [820.30
(j)] or quality system record file (820.186).
• The operational, monitoring, and other
production-related procedures are part of the
device master record (DMR) (820.181).

Process Performance
Qualification
• The purpose of process performance qualification is to
rigorously test the process to determine whether it is
capable of consistently producing an output or inprocess or finished devices which meet specifications. In
entering the process performance qualification phase of
validation, it is understood that the:
– device, packaging, and process specifications have been
established, documented, and essentially proven acceptable
through engineering, laboratory or other verification methods
[820.30; 820.70(a)]; and
– process and ancillary equipment and the environment have been
judged acceptable on the basis of installation and operation
qualification studies [820.70(g)].

Product Performance
Qualification
• Demonstrate that the process has not adversely affected the
finished product and that the product meets its predetermined
specifications and quality attributes.
• Products used for design validation should be manufactured using
the same production equipment, methods and procedures that will
be used in routine production.
• Design validation can be conducted using finished products made
during process validation studies and will satisfy the need for
product performance qualification.
• Design validation shall ensure that devices conform to defined user
needs and intended uses and shall include testing production units
under actual or simulated use conditions [820.30(g)].
• Original designs and design changes are subject to design control
requirements [820.30(i)]. The results of design validation are subject
to review under the design control review requirements [820.30(e)].
