Intro to cGMP & Quality Mangement Systems & Clean Room Policies

cGMP

current practices that ensure the manufacturing, testing, and quality assurance of pharmaceutical products; must align with industry regulations enforced by regulatory agencies

importance of cGMP

prevents contamination, errors, and defects in products; protects consumer health

regulatory bodies

FDA, EMA, WHO, ICH

key principles of cGMP

quality management, personnel qualification & training, facility & equipment maintenance, documentation & record-keeping, continuous improvement

CFR

Code of Federal Regulations

role of quality control

involves testing products to ensure they meet specifications, conducts lab tests to verify product quality, and compiles the evidence supporting product quality

role of quality assurance

focuses on preventing mistake during manufacturing, develops & enforces SOPs, and reviews & approves evidence supporting product quality

personnel & training

personnel must be adequately trained in cGMP principles such as understanding SOPs, hygiene practices, and equipment use

facility & equipment design

facilities are designed to minimize contamination risks; equipment must be regularly maintained, calibrated, and validated

metrology

the scientific study of measurement

documentation in cGMP

documentation ensures traceability and accountability; includes training evidence, maintenance, calibration, SOPs, batch records and testing logs

Standard Operating Procedures

outline step-by-step instructions for performing tasks to ensure consistency and compliance

production and process controls

“controls” are all of the checks and balances that are put in place to document & confirm that SOPs were followed; ensures that each product batch meets quality standards; involves in-process controls, monitoring, and adjustment

process validation

demonstrates that a process consistently produces a product meeting quality criteria; occurs in three stages - process design, process qualification, and continued process verification 

control of raw materials

raw materials must meet predefined quality specifications; includes sampling, testing, and approval processes; includes auditing raw material production facilities 

packaging and labeling controls

ensure the correct product is placed in the correct packaging with the correct label; prevent mix-ups, mislabeling, and cross-contamination; protect the integrity, stability, and traceability of the product

good laboratory practices (GLP)

ensures accuracy, reliability, and consistency of test results; includes proper handling of samples, equipment calibration, and data integrity

data integrity in cGMP

ensures that data is complete, consistent and accurate; ALOCA and ALOCA+ principles

ALOCA

Attributable, Legible, Contemporaneous, Original, Accurate

ALOCA+

complete, consistent, enduring, and available

environmental controls

includes air quality (HVAC systems), water systems, and cleaning protocols to prevent contamination of products

water systems in cGMP

types of water include purified water, water for injection WFI (not sterile), and sterile water

purified water (PW)

highly purified water used for non-parental formulations and cleaning

water for injection (WFI)

ultra-purified water suitable for parental (injectable) product preparation - not sterile

sterile water

WFI that has been sterilized and packaged in single-use containers

handling deviations

must conduct investigation, get results, propose, implement and validate new SOPs; must be documented, investigated, and corrected

change control

any changes to processes, equipment or materials must be controlled and documented; effect of change on process must be fully understood and change must not negatively impact product quality

corrective and preventative actions (CAPA)

corrective actions address existing issues and preventative actions prevent future occurrences of issues; CAPAs can prevent deviations & ensures continuous improvement

audit

a formal examination of some aspect of an individual, process, facility, etc

internal audit

conducted by the company to ensure compliance with standards, a key component of QMS maintenance and serves to identify areas needing improvement

external audit

conducted by regulatory agencies or third parties (FDA can inspect ANYTHING!!)

preparing for regulatory inspections

ensure documentation is up to date, train staff on inspection protocols, conduct regular self-audits as QMS, and address any potential compliance gaps

consequence of non-compliance

warning letters → product recalls → facility shutdowns → legal penalties (fines, disbarment, jail time)

benefits of cGMP compliance

ensures high product quality, reduces the risk of recalls and regulatory actions, and builds consumer confidence/trust for the brand

future trends in cGMP

increased focus on data integrity & digitalization, use of AI & machine learning in quality control, and continuous improvement

what is QMS?

a formalized system that documents process, procedures, and responsibilities for achieving quality polices and objectives; it helps organizations ensure product and service quality via a “comprehensive quality systems model”

importance of QMS

ensures consistent product quality, enhances customer satisfaction, facilities compliance with regulatory requirements, and promotes continuous improvement

key components of QMS

quality policy, quality objectives, documented information, process approach, and risk-based thinking

historical background of QMS

evolved from the early quality control systems in manufacturing; the ISO 9000 standard established in the 1980s

W. Edwards Deming

cultivated leadership role, continuous improvement, and the involvement of all employees in the pursuit of quality; systematic approach to quality management, focusing on reducing process variation through statistical process control

Joseph M. Juran

believed that quality should be managed like any other business function, top managements should be committed to quality (investigating in quality, not profit), a few causes are responsible for most problems

quality policy

a formal statement of an organization’s commitment to quality, provides a framework for setting quality objectives, and communicates expectations to employees and investors

quality objectives

specific, measurable goals related to quality which must align with the quality policy

documented information

includes policies, procedures, work instructions, and records; ensures consistency and traceability; must be controlled and maintained

process approach

emphasizes managing processes as a system; focuses on inputs, activities, and outputs; identifies interactions between processes (in an overall process, build efficiency)

risk-based thinking

encourages organizations to identify and address risks and opportunities; helps prevent issues before they occur; improves decision-making and planning

ISO 9001: 2015 Standard I

the most widely recognized QMS standard; provides a framework for managing quality; based on seven quality management principles

the seven quality management principles associated with ISO 9001: 2015 Standard I

1) customer focus 2) leadership 3) engagement of people 4) process approach 5) improvement 6) evidence-based decision making 7) relationship management

ISO 9001 - customer focus

understanding & meeting customer needs; enhancing customer satisfaction; building long-term relationships

ISO 9001 - leadership

top management must demonstrate commitment to quality, establishes a clear vision and direction, promotes a culture of quality within the organization

ISO 9001 - engagement of people

involves employees at all levels, encourages participation and feedback, recognizes contributions to quality improvement

ISO 9001 - process approach

managing activities as processes improves efficiency, identifies critical and potential failures, and supports consistent and predictable results

ISO 9001 - improvement

continuous improvement is essential for QMS effectiveness, strengthen the weakest link, utilizes tools like PDCA cycle, and encourages innovation and problem-solving

PDCA cycle

Plan-Do-Check-Act cycle

ISO 9001 - evidence-based decision making

decisions should be based on data and analysis, ensures objectivity and reliability, and reduces guesswork and assumptions

ISO 9001 - relationship management

managing relationships with stakeholders is crucial; includes suppliers, customers, and employees; and builds trust & mutual benefit

QMS implementation steps

1. define scope and objectives

2. develop and follow quality policies and procedures

3. train employees

4. conduct internal audits

5. continuously monitor and improve

role of documentation in QMS

provides a foundation for QMS; ensures consistency and traceability; and includes manuals, procedures and records

QMS in pharmaceutical industry

ensures compliance with cGMP regulations; focuses on product safety, efficacy, and quality; critical for regulatory approvals and audits

QMS tools and techniques

process mapping, root cause analysis, risk assessment, PDCA cycle, and six sigma

process mapping

identify processes and interrelations; understand sequencing such as inputs, core processes, outputs, and support processes

benefits of QMS

improves product and service quality; enhances customer satisfaction; reduces risk & operational costs; increases efficiency and effectiveness

challenges in QMS implementation

resistance to change, lack of management commitment, inadequate training & resources, and complex regulatory requirements

future trends in QMS

digital transformation and automation; integration with AI and machine learning; focus on data integrity and cybersecurity; sustainable and ethical practices

clean room classification (ISO 14644)

clean rooms are classified by allowable particle concentration and are categorized by ISO #; HVAC must meet classification at rest and in operation; impacts airflow, filtration, pressurization, and monitoring

cGMP clean room zoning

defined zone: critical, controlled, and support areas; HVAC maintains gradients between zones; pressure differentials prevent cross-contamination; zoning determines filtration, airflow, and monitoring needs

airflow principles

clean rooms use unidirectional or non-directional flow; laminar flow is vital in critical operations & turbulent flow adequate in lower classifications; airflow patterns validated during commissioning

filtration technologies

HEPA filters remove over 99.97% of 0.3 um particles; Ultra low particle filters remove over 99.999% of 0.12 for higher grades; pre-filters extend HEPA filter life and reduce load; filter integrity testing required per cGMP

temperature and humidity control

target setpoints depend on product/process needs; humidity impacts microbial growth and static generation; tight control reduces variability in operations; sensors must be calibrated and redundantly monitored

pressure differentials

pressure cascades maintain directional flow; high-to-low gradients protect critical spaces; door openings and equipment placement affect stability; differential pressure gauges and alarm are required

air changes per hour (ACH)

higher ACH dilutes contaminants effectively; ACH requirements vary depending on the ISO #; energy consumption balanced with contamination control & the ACH must be verified during qualification

HVAC and contamination risk assessment

risk assessment per ICH Q9 guides design & monitoring; higher risks require redundancy and stricter controls; HVAC is closely tied to contamination control strategy (CCS); risk-based monitoring ensures efficient resource allocation

material and personnel flow

HVAC supports unidirectional movement to reduce contamination; airlocks and pass-throughs maintain pressure integrity; changes in personnel behavior influence contamination load; flow mapped during facility design

return air and exhaust system

return air placement impacts turbulence and cleanliness; exhaust systems used for hazardous or potent compounds; balancing ensures adequate circulation and pressure control; exhaust failure alarms are critical for safety

monitoring of airborne particules

real-time monitoring in critical areas; trending required for state-of-control evaluation; alerts and action levels established using USP1116

microbial monitoring

active and passive methods used; HVAC affects airborne microbial load and recovery rates; data trending used for a contamination control strategy; deviations trigger investigation and CAPA

controlled non-classified areas (CNC)

these areas may support clean rooms depending on operations; HVAC is less strict but still regulated to prevent contamination; pressure relationships maintained with adjacent ISO rooms; often monitoring at reduced frequency

clean room commissioning

includes design review, installation verification, and function checks; ensures HVAC meets operational needs before qualification; documentation required for GMP compliance; commissioning precedes IQ/OQ/PQ

qualification: IQ/OQ/PQ

IQ verifies installation per design specifications; OQ tests functions under controlled conditions; PQ tests performance during operation; HVAC must pass airflow, particle and pressure tests

alarm and control systems

BMS/EMS monitor HVAC continuously; alarms for T/H, pressure, and particle excursions; remote notification critical for 24/7 operations; audit trails required for data integrity

redundancy and reliability

redundant fans, filters and sensors improve robustness; critical spaces may use N+1 design; minimizes downtime and product loss; risk-based justification required for redundancy levels

energy efficiency in cGMP HVAC

clean rooms are energy-intensive with impactful efficiency; variable air volume systems are used where allowed; heat recovery systems reduce utility costs; must maintain compliance while conserving energy

common HVAC deviations

pressure loss, temperature drift, or filter failures; human factors such as doors proposed open, poor maintenance; each deviation requires documented investigation and CAPA system ensures prevention of recurrence

maintenance requirements

preventative maintenance essential in GMP facilities; HEPA replacement schedule based on performance (not time alone); calibration of sensors ensures accuracy and reliability; documentations must be GMP-compliant

cleaning and sanitization impacts on HVAC

cleaning chemicals can damage filters or coils; HVAC must withstand disinfectants used in the clean room; cleaning activities impact airflow and particle levels; procedures aligned with validated cleaning program

emerging technologies

smart sensors for real-time monitoring; advanced modeling for airflow and pressure control; energy-optimized clean rooms with predictive maintenance; integration with digital quality systems
