Janssen Pharmaceutica NV • A Global Pharmaceutical Company • A pharmaceutical company of Johnson & Johnson • HQ in Beerse, Belgium • Multiple R&D sites in Europe, US, China and India Janssen, Beerse, Belgium Janssen, Geel, Belgium
Outline • Background & Challenges in Pharmaceutical R&D • Overview of LEA platform in Janssen Pharmaceutical Research & Development • Case Studies: • Excipient Compatibility • Accelerated Stability Assessment Program (ASAP)
Our challenge in pharmaceutical R&D • More complex products (the easy ones are gone) • Constantly increasing regulatory and patient expectations • Cost of drug development is rising exponentially, and timelines are expanding • We need more shots on goal due to high attrition • Need more killer experiments The solution???
Drug Product Development • Can be developed only if • Bioavailability • Processability • Stability • are achieved simultaneously • Parallel concept development is the major approach to accelerate drug product development process
Parallel concept development – a design space perspective • Need systematic experimentation, e.g.DoE • Parallel concept development • Need higher throughput • Down-scaling and automation is the key Narrowed design space Entire design space Good stability subspace Good processability subspace Good bioavailability subspace
Challenges with down-scaled, automatic experiments Amount of information Smaller scale and more automation Progress of experiment

Product Design and Developability Workflows • Support to Drug substance and drug product development • 16 active screening workflows implemented and used as part of our platform-based development approach
PART I. Excipient Compatibility – The Dynamics of Drug Product Stability
Excipient Compatibility • Study chemical compatibility behavior between API and excipients • Closely related to drug safety and efficacy • Normally carried out in early development phase • Sometimes included in the preformulation package • Solid state form selection need to be done before excipient compatibility • Final morphology, particle size are preferred • Final synthesis route is best in place
Different Approaches Towards Excipient Compatibility • 1:1 mixtures • Easy to set-up • May overestimate (Not the actual ratio) • May underestimate (Synthetic effect) • Full Blend then N-1 method (remove one excipients per time) • Gives more information • 2-step method • More time consuming • DoE approach – Mixture Design • Able to predict the dynamics of mixture • Much more samples need to be prepared
Challenges to conquer before getting the benefits of mixture DoE • Powder dispensing • Mixing powder homogeneously in small scale

Mixing in Small Scale • Vortex Mixing • Particle size/morphology not affected • Mixing efficiency depends on load • Gentle mixing • Magnetic stirrer bar/disk • Particle size/morphology may affected • Longer mixing time • Turbula Mixer • Particle size/morphology may affected • Good mixing efficiency • Gentle mixing Blend Load (mg) Vortex mixing speed (rpm)
Case Study I: Compound X formulation challenge • Standard capsule formulation • Poor flowability (formulator suggested to add more silicon dioxide) • High Dose (around 50% API load) Medium silicon dioxide High silicon dioxide No silicon dioxide
Case Study I: Compound X formulation challenge • Silicon dioxide could cause degradation • Interactions between silicon dioxide with fillers were revealed • Optical formulation ranges can be suggested from stability perspective • The amount of silicon dioxide need to be carefully controlled • Mixture DoE and small-scale experiments can be used for excipient compatibility studies
PART II. Accelerated Stability Assessment Program– The Kinetics of Drug Product Stability
The concept of Accelerated Stability Assessment Program (ASAP) • Relative Humidity corrected Arrhenius equation • Isoconversion • Monte-Carlo simulation • Packaging 70°C % Degradant 50°C 25°C Time KC Waterman, AAPS PharmSciTechVol 12 No.3, September 2011
Case Study II: Bench Mark the Stability Behavior of Compound Y concepts • Compound Y is under BCS Class II (Low solubility, high permeability) • Need amorphous solid dispersion to boost bioavailabiilty • 28 amorphous solid dispersion concepts were investigated • Need to predict/compare shelf life for each concepts • 12 samples need to be prepared for each concept according to ASAP • 336 samples in total prepared by CM3
Case Study II: Bench Mark the Stability Behavior of Compound Y concepts The samples preparation is finished within 2 days on CM3 … • Automation enabled timely stability study for parallel drug product development • Shelf-life can be predicted via ASAP approach
Conclusion & Challenges • With DoE and ASAP, down-scale and automation has added-on value for stability studies • Parallel drug product development could benefit from down-scale and automation • CM3 is not GMP certified yet • Combine dynamics and kinetics studies • Data handling challenge (HPLC peak identification)
