Discusses quality systems in research labs, testing labs, and production facilities in the biotechnology field. Explains informal and formal quality systems, oversight, consequences of poor quality, and regulatory compliance.
E N D
OVERVIEW • Talk about product quality systems • In broad way • Apply ideas to the various work places we talked about
QUALITY SYSTEMS • Broad systems of regulations, standards, or policies that ensure the quality of the final product
Discussion of product quality and quality systems leads to… • Regulatory affairs • Interaction of government with the industry • Which for biotechnology…. • Takes us to GMP
WHAT IS PRODUCT QUALITY? • What is a “good” product in biotechnology? • That depends… • Consider biotech: • Research labs • Testing labs • Production facilities
QUALITY PRODUCT: RESEARCH LAB • Research lab, knowledge is product: • Knowledge of nature (basic research) • Understanding of technology (applied research, R&D)
QUALITY SYSTEMS IN RESEARCH LABS • Quality system in research • Ensure meaningful data • has been around a long time • It is called:
“DOING GOOD SCIENCE” • Less formalized than other quality systems • No one book spells it out • No laws to obey • But it exists
INFORMAL SYSTEM • Consequences of poor quality product not life-threatening so • Government seldom involved in monitoring research quality • Oversight not generally by outside inspectors or auditors
BUT THERE IS OVERSIGHT • Oversight is by peers • Grant review • Publications • Reputation
CHANGE: RESEARCH LABS • Change is good • Basis for advances • Flexibility is valued • Willingness to change directions is necessary
SUMMARY: RESEARCH LABS • Quality system: “Doing Good Science” • Least formal • Not found in any one book • No laws to follow • No enforcement by regulatory agency • Change is accepted • Oversight is by peers
Compare and contrast situation in research labs and other work places
PRODUCT QUALITY: TESTING LAB • Testing lab: • Information about samples that can be relied on when making decisions
CONSEQUENCES • A poor quality product can be life-threatening or have serious effects
QUALITY SYSTEMS IN TESTING LABS • Include most of what we call “doing good science” plus • Specific formal requirements • Personnel • Equipment • Training • Facilities • Documentation…
You can find a book that spells it out for: • Clinical labs • Forensic labs • Environmental labs…
ENFORCEMENT: TESTING LABS • Since consequences of poor product can be life-threatening • Is outside oversight • FBI • EPA • Etc.
CHANGE: TESTING LABS • Change is controlled • May improve test methods, but • Test new methods against old ones • Document changes • Control change
PRODUCT QUALITY: PRODUCTION FACILITY • Make tangible items • Quality means fulfill intended purpose • Ex.: reagent grade salt vs road salt vs table salt
QUALITY SYSTEMS IN PRODUCTION FACILITIES • Depends on nature of product • Poor product may or may not have life-threatening consequences
SO, FOR EXAMPLE • Products for research use, not generally regulated • Agricultural products are regulated in one way • Pharmaceutical products are regulated in another
VOLUNTARY STANDARDS • Companies that are not regulated may choose to comply with a product quality system for business reasons
ISO 9000 • ISO 9000 • Formal product quality system • Extensive • Exists in a series of books • Companies comply voluntarily to improve the quality of products • …and to make more money
Developed by the International Organization for Standardization (ISO) • International
OVERSIGHT: ISO 9000 • Oversight by outside auditors, paid by company
CHANGE: ISO 9000 • Change is controlled • Deviations monitored • Operation of systems maintained in narrow range
BIOTECH AND MEDICAL PRODUCTS • Many biotech companies that make money make medical/pharmaceutical products • Consequences of poor product can be life-threatening
SO… • These products are highly regulated by the government • But, it wasn’t always this way…

“THE JUNGLE” • Upton Sinclair described shocking conditions in food industry in U.S.
CANNOT SELL ADULTERATED PRODUCTS “A drug or device shall be deemed adulterated – (a)1 if it consists in whole or part of any filthy…substance (2) (A) If it has been prepared, packed, or held under insanitary conditions whereby it may have been contaminated with filth…
Or (B) if it is a drug and 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 current good manufacturing practice to assure 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…”
KEY IDEAS: 1906 FDCA • Adulteration • Good manufacturing practices, which we now call cGMP • FDA (Food and Drug Administration) eventually established to interpret and enforce this law
SULFANILAMIDE -- 1937 • Diethylene glycol used to dissolve sulfanilamide • Hundreds of people died, mainly children
First drug recall, because the drug was labeled “elixir” and had no alcohol
KEY IDEAS: 1938 FDCA • Required new drugs to be shown SAFE • Eliminated requirement to prove intent to defraud in drug misbranding cases. • Extended control to cosmetics and therapeutic devices. • Authorized factory inspections…
CROSS-CONTAMINATIONSULFATHIAZOLE • Nearly 300 deaths and injuries resulted from sulfathiazole tablets tainted with phenobarbital. • FDA dramatically revised manufacturing and quality controls -- good manufacturing practices (GMPs).
KEY IDEAS: GMP REGULATIONS 1941 • Cover actual manufacturing • Raw materials must be good • Must have lab testing of raw materials, samples as you go along, products • Facilities, personnel, equipment must be good • Documentation
Safety Testing Approval Process Revised GMP Regulations 1941
THALIDOMIDE -- 1960 • Sedative that appeared safe but in reality caused severe birth defects • Thousands of children affected throughout Europe • Led to tightened laws
CONTAMINATED IV BAGS --1976 • Septicemia • 1960s and 1970s there were many cases caused by IV fluids contaminated with bacteria. • Many people died
FDA INSPECTIONS • Found serious problems: • Contaminated cooling water • Sterilization equipment that did not reach sterilizing temperature • Contamination
