cGMP and GLP Regulations and Inspections for Quality Control Labs - An overview


A large number of quality control related 483s and warning letters in recent years demonstrate that regulated companies are having problems with the implementation of regulations for quality control laboratories. FDA and other agencies have held inspections of QC laboratories in the highest emphasis because the drug products and APIs (Active Pharmaceutical Ingredient) are released to the market after testing and approval without any further check. This article provides the regulatory background and informs you of what the inspectors will check during inspections.

In addition to reading this article, a demonstration of how quality control and quality assurance personnel can monitor industry practices to stay "current" with FDA requirements (cGMPs and GLPs) will be helpful. The seminar Quality Control Laboratory Compliance - cGMPs and GLPs takes a deep dive into the topic.

GMP requirements for Quality control laboratories B'211.160

for Quality control laboratories

'General requirements:

  • Scientifically sound and appropriate specs
  • Establish written specs, sampling, procedures
  • Conformity to written specifications
  • Calibration of instruments
  • Conformance to appropriate standards of identity, strength, quality, & purity
  • Test results documented at the time of performance
  • Appropriate procedures for the acceptance of components, in-process materials, and drug products
  • Methods must be documented and approved

Testing and Approval or Rejection of Components:

  • Hold back from use each lot of component, drug product containers, and closures until the lot has been sampled, tested, or examined and released for use
  • The Representative sample consists of a number of units that are drawn based on rational criteria such as random sampling and intended to assure that the sample accurately portrays the material being sampled.
  • At least one specific identity test is conducted on the component by the manufacturer at the time of receipt.
  • The manufacturer establishes the reliability of the supplier's analysis by validating the supplier's test results at appropriate intervals.

Sampling and Testing of In-process Materials and Drug Products:

  • Written procedures shall be established and followed for inprocess testing
  • In-process materials shall be tested for identity, strength, quality, and purity, and approved or rejected by the QU
  • Testing of samples shall assure that the drug product and in process material conform to specifications

Testing and Release for Distribution:

  • Documented accuracy, sensitivity, specificity, and reproducibility of test methods
  • Test each batch for conformance to specifications
  • Follow written sampling and testing plans
  • Document testing methods and number of units/batch

Drug Product Stability Testing:

  • Written stability testing program
  • Full shelf-life studies for determining the expiration date
  • Combination of accelerated studies and basic stability
  • Conducted on samples from representative batches
  • Sample size and test intervals based on statistical criteria

Reserve samples:

  • Reserve samples from representative sample lots or batches
  • Stored under conditions consistent with product labeling
  • Results of the examination shall be recorded and maintained with other stability data on the drug product
  • Investigate any evidence of reserve sample deterioration

Laboratory Records:

  • A description of the sample
  • The location of the method validation data
  • A description of the suitability of the method
  • Record of the sample weight including all test data obtained
  • A statement that test methods are accurate, reliable, and followed'

GLP regulations (21CFR part 58)

GLP regulations are published is CFR part 58 and apply to

Non-clinical laboratory studies that support or are intended to support application for research or marketing permits for the following products:

  • food and color additives
  • human and animal drugs
  • medical devices for human use
  • biological products
  • electronic products

(58.3)

"In vitro or in vivo experiments in which test articles are studied prospectively in test systems under laboratory conditions to determine their safety. The term does not include studies utilizing human subjects or clinical studies or field trials in animals.

The term does not include basic exploratory studies carried out to determine whether a test article has any potential utility or to determine the physical or chemical characteristics of a test article."

Elements of GLP

Elements of GLP

Management Responsibilities (58.31):

  • Before initiating the study, designate a Study Director
  • Ensure there is a Quality Assurance Unit
  • Ensure that the test and control article have been appropriately tested for identity, strength, purity, stability and uniformity, as applicable
  • Authorize significant changes in SOPs
  • Ensure that any deviation from GLP regulations reported by the quality assurance unit are communicated to the Study Director and corrective actions are taken and documented

Study Director:

"For each non-clinical laboratory study, a scientist or other professional of appropriate education, training and experience, or combination thereof, shall be identified as Study Director".

Quality assurance unit:

"A testing facility shall have a Quality Assurance unit which shall be responsible for monitoring each study to assure management that the facilities, equipment, personnel, methods, practices, records, and controls are in conformance with the regulations.

For any given study, the Quality Assurance unit shall be entirely separate from and independent of the personnel engaged in the direction and conduct of the study."

Testing Facility:

"A testing facility shall have standard operating procedures in writing setting forth non-clinical laboratory study methods that Management is satisfied are adequate to insure the quality and integrity of the data generated in the course of a study.

"Each laboratory area shall have immediately available laboratory manuals and standard operating procedures relative to the laboratory procedures being performed. Published literature may be used as a supplement to standard operating procedures."

"A historical file of standard operating procedures, and all revisions thereof, including the dates of such revisions, shall be maintained."
