Grange Castle Products The first advance in 20 years for the treatment of moderately to severely active rheumatoid arthritis (RA) in adult and juvenile patients Pneumococcal-Meningicoccal Vaccine Relistor is a new product, which will be used for the treatment of opioid-induced side effects, including constipation and post-operative bowel dysfunction. Antibiotic – for the treatment of complicated intra-abdominal infections
Recruitment • 80,000 job applications to date • 25,000 Interviews conducted to date • 1,224 full time employees in place today • 220 full time contractors • 11% of employees relocated from international locations • Half of this group are Irish people returning home • 95% with third level qualifications • 55% male; 45% female • Average age 37
Aim of Module • Experienced Process Engineer working in the industry • Invite any Questions I may be able to answer from my experience • Assignment - aim is to try to get you thinking in a real life ‘facility design’ frame of mind • Give you as much knowledge/ experience to allow you use your skills & knowledge
Facility Design & Operation • 1) Introduction • 2) Aseptic Processing • 3) Process Stages • 4) Utilities Introduction (inc HVAC)
Learning Outcomes At the end of this Lecture you should be able to ….. • Describe what is meant by Aseptic Processing • Define what is meant by a Critical Process step • Define types and sources of Contamination in Aseptic operations • Describe how contamination risk is minimised • Describe key factors influencing facility design • Describe the process steps in a typical Aseptic process • Define the area Classification Requirements for typical process steps • Describe what is meant by ‘Direct’ and ‘Indirect’ impact utility systems
Sterile Processing • Parenteral Drugs: • Injectable drugs bypass the body’s natural defences so must be sterile • Terminal Sterilisation: • Sterilise drug in final container (after manufacture and packaging) • Preferred method of sterilisation • Moist Heat Sterilisation • Gamma Radiation • E-Beam • Microwave • Many drugs not suitable for this method of sterilisation • Aseptic Processing: • Individual components are sterilised separately and brought together in the final form in a sterile environment.
Aseptic vs. Sterile • Definition of Aseptic “Free of or using methods to keep free of Pathological Micro-organisms” synonym : sterile • Sterile processing area is also know as the Aseptic Processing Area, Critical Processing Area or Sterile Core.
Aseptic Facility Design • Aseptic Processing AreaArea where critical process steps carried out • Critical Process StepsActivities during which the sterilised product and container / closure are exposed to atmosphere Design must minimise challenge to Aseptic Processing Area – HOW? Flow of raw materials, components, drug product containers, closures, in-process materials, drug products and people through the facility shall be designed to prevent contamination.
Contamination – Types & Sources • Non-Viable (Particulates) including Endotoxins • Sources: Equipment, Clothing, Water, Air • Viable (Micro-Organisms) • Sources: Equipment, People, Water, Air, Tools, Excipients, Active Ingredients
Contamination – Preventative Measures • Non Viable: • Contact Parts are cleaned and sterilised • Water is purified • Air is HEPA Filtered • Viable: • Interventions in sterile core are minimised • Solutions are sterile filtered through a 0.2m filter • Air is HEPA Filtered
Design concept to minimise challenge to Aseptic Processing Area Fig 2.1 Nested Manufacturing Zone (ISPE Guideline Vol 3)
Aseptic Facility Design Fig 2.2 Sterile Manufacturing Flowchart (ISPE Guideline Vol 3) • Highlights interdependence of operations in support of the core sterile activity • Highlights importance of support area design to GMP Compliance of Aseptic Processing Area
Exercise 1 You are members of a project team designing a new sterile product (s) facility – Discuss what product / process information you would need to ensure the facility can handle this new product
Exercise Answer Key Factors Influencing Facility Design • Product • Form - liquid/ powder (lyopholised) • Product Characteristics- light sensitive/ Excipients- number, quality, form, hazards etc. • Presentation- vials/ syringes • Market- market need, regulatory requirements- IMB/ FDA
Exercise Answer Key Factors Influencing Facility Design • Process • Degradation with thermal sterilisation? • Process duration - will impact production capacity • Cross Contamination Issues - e.g. strong antibiotics • Current Facility Capacity - spare capacity or shortfall
