Introduction
• In the process of developing the new product the batch size used in the earliest human studies are small.
• The size of the batch is gradually increased (scale up)
• The scale up and the changes made after approval in the composition manufacturing equipment and change of
site have become known as scale up and post approval changes (SUPAC).

11. Bulk Active Chemical Post Approval Changes (BACPAC)
This guidance provide recommendation to holders of NADAs (New animal drug application), ANADAs
(Abbreviated new animal drug application),VMFs (Veterinary Master Files)
Post approval changes include,
• Site of manufacture
• Scale of manufacture
• Equipment
• Specifications
• Manufacturing process of intermediates in synthetic pathway leading to drug substances
The Guidance Covered,
• Site, scale, and equipment changes involving the synthetic steps up to and including the step that produces the
final intermediate
• Specification changes for raw materials, starting materials, and intermediates, except the final intermediate
• Manufacturing process changes involving the synthetic steps up to and including the final intermediate.
12. Types of Changes
Site, Scale, and Equipment Changes
• The manufacturing site, scale of manufacture, and manufacturing equipment changes discussed in this section do
not include any modifications to the synthetic pathway (i.e., the same starting materials, intermediates, solvents,
and reagents are involved).
Site Changes
• Changes to a different manufacturing site should be reported. Changes within the same manufacturing site need
not be submitted to the Agency, and equivalence testing as described in this document need not be carried out.
Test documentation (submitted as amendments to master files and/or in annual reports or supplements to the
applications, as appropriate) should include.
• The name and address of the new facility.
• A concise description of the manufacturing steps being transferred, a summary of any variation in equipment or
operating conditions, and a statement that the synthetic pathway is identical at the new site.
• Evaluation of the impurity profile and physical properties.
13. Scale Changes
• Scale changes include increases and decreases in the batch size of intermediates, Including the final
intermediate, beyond those approved in the original application.
Equipment Changes
• A change to new equipment need not be submitted to the Agency, even where equipment is specified in the
approved application.
Specification Change
• Specification changes for the final intermediate are not included in this guidance, nor are certain specification
changes for raw materials, starting materials, and intermediates derived from natural sources or biotechnology
(see section I).
• Test documentation (submitted in amendments to master files and/or in annual reports to the applications, as
appropriate) should include
14. • Specification Changes That Provide Greater Assurance of Quality
• Test documentation (submitted as amendments to master files and/or in annual reports to the applications, as
appropriate) should include,
• Rationale for the proposed change and a brief description of any new analytical procedures, including a
discussion of improvements over existing procedures.
• Updated specifications.
• Some specification changes that fall within the scope of section V.B.3 would clearly not affect the quality of
downstream intermediates or the drug substance and therefore no evaluation of equivalence would be needed.
• Elimination of a redundant test (e.g., deletion of a boiling point test for a solvent where a chromatographic assay
test is routinely performed).
Manufacturing Process Changes
• This category encompasses a wide range of process related changes. New specifications may be called for when
different solvents, reagents, starting materials, or intermediates are involved,
15. Changes That Do Not Involve New Starting Materials or Intermediates
• Changes in unit operations (e.g., addition, deletion, change in the order, repetition of an existing unit operation
on a routine basis).
• Addition or deletion of raw materials (e.g., solvents, reagents) or ancillary materials (e.g., resins, processing aids)
• Changes in solvent composition (other than for an analytical procedure, which would be covered under
Specification Changes)
• Operating conditions (e.g., temperature, pH, reagent stoichiometry, time).
• Test documentation (submitted as amendments to master files and/or in annual reports or supplements to the
applications, as appropriate) should include,
• Description of change
• Specifications for new reagents and solvents and Certificates of Analysis from the suppliers, if applicable
• Evaluation of the impurity profile and physical properties.
16. Changes in the Route of Synthesis in One or More Steps Involving Different Starting Materials and/or
Intermediates (except the final intermediate)
• Test documentation (submitted as amendments to master files and/or in supplements to the applications, as
appropriate) should include,
• Description of the change with details of the new synthetic procedure, the operating conditions, and controls of
critical steps and intermediates
• Appropriate structural characterization data for new intermediates
• Specifications for any new starting materials and/or intermediates
• Evaluation of the impurity profile and physical properties.
Changes in Which an Intermediate Is Redefined as a Starting Material
• This change is often in response to an increase in commercial availability of the proposed starting material. In
general, the specification for the proposed starting material should
17. • Test documentation (submitted as amendments to master files and/or in supplements to the applications, as
appropriate) should include,
• Rationale for the proposed change and overview of current synthetic procedure
• Evidence that the intermediate complies with the current definition and/or expected characteristics of a starting
material
• A new or revised specification, a description of new or revised analytical procedures for the redefined starting
material, and, if appropriate, additional tests and/or tightened acceptance criteria for downstream intermediates
• A list of sources of the redefined starting material
• A description of how the suitability of a new supplier or revised process from an existing supplier will be
assessed
• Evaluation of the impurity profile and physical properties.
18. Post Marketing Surveillance
• Despite CDER's vigilant premarket review, active post marketing surveillance of drug adverse effects is also
essential.
• Because all possible side effects of a drug can't be anticipated based on preapproval studies involving only
several hundred to several thousand patients, FDA maintains a system of post marketing surveillance and risk
assessment programs to identify adverse events that did not appear during the drug approval process. FDA
monitors adverse events such as adverse reactions and poisonings.
• The Agency uses this information to update drug labeling, and, on rare occasions, to reevaluate the approval or
marketing decision.
• This page describes how CDER works to assure the ongoing safety and effectiveness of drug products currently
marketed in the United States.
• The FDA Adverse Event Reporting System (FAERS) is a computerized information database designed to support
the FDA's post-marketing safety surveillance program for all approved drug and therapeutic biologic products.
19. • The ultimate goal of FAERS is to improve the public health by providing the best available tools for storing and
analyzing safety reports. The reports in FAERS are evaluated by a multidisciplinary staff safety evaluators,
epidemiologists and other scientists in the Center for Drug Evaluation and Research's (CDER) Office of
Surveillance and Epidemiology to detect safety signals and to monitor drug safety.
• As a result, the FDA may take regulatory actions to improve product safety and protect the public health, such as
updating a product's labeling information, sending out a "Dear Health Care Professional" letter, or re-evaluating
an approval decision.
• The MedWatch program is for health professionals and the public to voluntarily report serious reactions and
problems with medical products, such as drugs and medical devices.
• It also ensures that new safety information is rapidly communicated to the medical community thereby improving
patient care.
• All data contained on the MedWatch form will be entered into the AERS database. The MedWatch page includes
sections on how to report an adverse event, safety information, and publications. For more information on how to
report adverse events, see Reporting Problems to FDA.
20. • The Division of Drug Marketing, Advertising and Communications page also contains other useful drug
advertising and surveillance information.
• After a drug is approved and marketed, the FDA uses different mechanisms to assure that firms
i. Adhere to the terms and conditions of approval described in the application
ii. That the drug is manufactured in a consistent and controlled manner. This is done by periodic,
unannounced inspections of drug production and control facilities by FDA's field investigators and
analysts.
• Manufacturers of prescription medical products are required by regulation to submit adverse event reports to the
FDA.
• The MedWatch site provides information on mandatory reporting by manufacturers.
• In addition, drug manufacturers must submit either error and accident reports or drug quality reports when
deviation from current good manufacturing practice regulations occur.
21. • Therapeutic Inequivalence Reporting. In the past 10 years, FDA's Center for Drug Evaluation and Research has
received an increase of reports of drug products that fail to work in patients because the product simply has no
effect or is toxic.
• These problems are usually attributed to switching brands of drugs. As a result, on Sept. 14, 1988, FDA created
in CDER the Therapeutic Inequivalence Action Coordinating Committee (TIACC) to identify and evaluate
reports of therapeutic failures and toxicity that could indicate that one product is not equivalent to another
similar product.
