PRODUCT LIFE CYCLE CONCEPT

Linking target product profile, process development and process

qualification to demonstrate sustainable quality, safety and

efficacy.

Process lifecycle

• Process design

• Process qualification

• Continuous process verification

Approach

• Traditional

• Enhance

• Hybrid

IMPLEMENTING LIFECYCLE AND

CONTROL STRATEGY

Definition phase

Bigger picture! Example

The source of active material Plant (whole, leaf, fruit seed etc.)Percentage of active and related substance

Target compound (the molecule) StructureSolubilityPolymorphismChirality

Target patients Human Veterinary medicine

Potential dosage form OralTopicalInjectable

Target product profile Identity, strength, purity, potency, safety and other Critical Quality Attributes (CQA)

Process Analytical Technology Off-line, at-line on-lineIR, NMR, HPLC, GC, MSMS

Demand vs process scalability Grams, Kg, Tons

• Physical Appearance• Compare with

botanically certified standard

• HPTLC identification or HPLC finger printing

• Assay (> X %)• Moisture content

EXAMPLE CONTROL STRATEGY

Processing Technology Screening

Lab (small) Scale Manufacturing

Large Scale Development Batches

Commercial Batches

• Record everything! • Test everything!• Collect, data for CPP

such as temperature, time, pH, pressure, vacuum etc.

• Recovery and process efficiency for each step.

• Study reprocessing capabilities

• Reduce in process testing• Include meaningful in

process testing• Introduce upper and

lower range for temperature, time, pH, pressure, vacuum etc

• Finalise reprocessing pathways

• Finalised in-process specification and acceptance criteria

• Tightened range of CPP• Implement reprocessing

policy and procedures

Process Control

• Physical Appearance• Identification FTIR, HPLC• Assay % (report results)• Impurities (all impurities,

Report result)• Moisture content• More testing is better

• Physical Appearance• Identification FTIR, HPLC• Assay % (report results)• Impurities (all impurities

, Report result)• Moisture content

(Report result)• Elemental impurities

(USP) • Residual solvents (Report

result)• Micro (USP)• Endotoxin (Report result)

• Physical Appearance• Identification FTIR, HPLC• Assay % (> X %)• Specified Impurities (≤ X

% impurities , above identification threshold or degradation impurities)

• Unspecified Impurities (≤ X % impurities , above Reportable

• Moisture content (Report result)

• Elemental impurities (USP)

• Residual solvents (Report result)

• Micro (USP)• Endotoxin (Report result)• Residue on ignition

• Too far • Team building • Training

• Planning• Timing• No of batches

• Batch record fine tuning• Master plan and Protocol

• Testing high risk CQA and CPP

• Smooth Execution of PVP• Continued verification

CHALLENGES

• Understanding source of variability and degree of variation

• Linking the impact of variation to the CQA of the product

• Controlling variation while maintaining sustainable yield

• Balancing quality and commercial viability

• Collaboration of multidisciplinary functions such as R&D, clinical,

quality, regulatory

• Time

• Resources

• Organisational culture and mindset

doomed to repeat it.”
