The Biomanufacturing Process Introduction to Biotechnology
Getting a Drug to Market • US Food and Drug Administration is the main consumer watchdog for pharmaceuticals in the USA. • FDA evaluates new drugs (prescription and OTC) before they can be sold. • How would you describe the FDA’s role in regard to consumers?
Getting a Drug to Market • The development of a new drug is lengthy and expensive for BOTH chemical pharmaceutical and biopharmaceutical industries. • As the process moves from lab to manufacturing, the size and variety of jobs grows. • Can you anticipate the types of jobs you might find in biomanufacturing?
Drug Discovery and Testing • In the past, drug discovery was done by trial and error. • With biotechnology, scientists have a better understanding of life processes, which helps the drug discovery process. • Based on your understanding of how genes and proteins work, can you think of any drugs a scientist might go looking for?
Drug Discovery and Testing • Drug discovery begins in the laboratory. • Promising drugs pre-clinical studies with animals and non-human test systems. • If pre-clinical trials promising, company may file Investigational New Drug Application (IND) with the FDA.
Clinical Trials • Before FDA approval, human studies to test drug effectiveness. • It takes 2-10 years, average 6 years. • If clinical trials indicate drug is safe and effective, the company files a New Drug Application (NDA) with the FDA. • NDA averages 2 years to be approved.
Clinical Trials • Final step in Clinical Trials is Post-Marketing Surveillance • This system monitors the safety of a marketed drug, and includes adverse action reporting from the medical and pharmaceutical communities. • Are drugs ever taken off the market during Post-Marketing Surveillance?
Production • Synthesis (chemical or cell culture) • First, the materials needed for the creation of the product are prepared. • Second, the product is created, either by chemical synthesis (traditional pharmaceuticals) or through cell culture or fermentation (biomanufacturing).
Purification • Purification is the process of separating the bulk product from the leftover chemicals or cellular byproducts. • What cellular byproducts do you think there would be in biomanufacturing?
Formulation and Final Form • Chemical mixing to blend bulk product (active ingredient) with other substances such as fillers. • Final dosage form preparation • Made into final form (tablets, sterile solutions) • Dispensed into containers • Do you think the final form has any bearing on the sale of a drug product?
Quality Control (QC) • All employees must follow Good Manufacturing Practices (GMP) and FDA regulations. • Quality Control – testing product during stages of the manufacturing process. • Why is quality control important in biomanufacturing?
Quality Assurance (QA) • Quality assurance follows Standard Operating Procedures (SOPs) which define each procedure in detail so it can be performed exactly the same way every time. • Both QA and QC require all process details and checks in writing. • “If it isn’t written down, it never happened.”
Validation • Validation proves that the manufacturing process will produce an exact product when carried out exactly with specified equipment. • Do you know of anything that must be “validated”? Why?
The Price of Poor Quality • To be competitive in any industry, companies need to produce high quality products. • What happens to companies when they produce poor quality products?
Five Rules for Quality • Understand customer needs. • Say what you do – write down procedures. • Do what you say – follow procedures. • Prove it – keep records. • Improve it.
Standard Operating Procedures • SOPs define a particular process in detail so that it can be performed the same way every time. • Biomanufacturing is regulated by the FDA, which requires companies to follow their SOPs. • Regulations that regulate pharmaceutical manufacturing are known as Good Manufacturing Practices (GMPs).
Summary • How does a drug get to market? • What is a clinical trial? • What organization regulates biomanufacturing? • What does quality mean? • What are standard operating procedures and regulations?
