FDB Single-Use Bioprocessing Journey Learning from Early Adoption of Single-Use Technologies Process Design Goals for New Facility Facility Layout, Room Classifications, and Closure Strategy Upstream and Downstream Single-Use Processes and Equipment Modeling to Design Small (2 g/l), Medium (5 g/l), and Large (8 g/l) Downstream Process
Creating biomanufacturing capacity A global partnership Driven by the industry need for cgmp mammalian cell culture biomanufacturing capacity Four successful capacity expansion projects on two continents Creating the UK s first fully single-use biomanufacturing facility 1000 L project Single-use WAVE Bioreactor systems Xcellerex XDR cell culture suite ÄKTA ready and ReadyToProcess prepacked columns Billingham, UK 2013 2014 2000 L project Xcellerex XDR 2000L bioreactor added Research Triangle Park, US 1000 L project 2012 Xcellerex single-use mixers Xcellerex XDR cell culture suite ÄKTA ready purification system Research Triangle Park, US 2015 2000 L project Xcellerex XDR 2000L bioreactor added Billingham, UK Ongoing partnership 2017 2018 2019
Development of FDB Single Use Bioreactor Platform Why Single Use? Capacity can be increased quickly Capital investment and payback time are less Footprints are reduced Less utilities are required (CIP/SIP) No cleaning verification/validation Less cost for room classifications, EM monitoring, personnel gowning/flow Multi-product manufacture ( ballroom ) suites Multiple products in multiple suites (reduced changeover times) Production Bioreactor Selection Process performance (mixing, mass transfer, sparger flexibility) Engineering design (hardware and bag design) Control system capability and automation tie-in Equipment cost and product support Speed and ease of implementation and qualification Track record

Upstream Learning from Early Adoption Hardware Design MFC sizing Automated exhaust filter strategy SUB Bag Design Enough addition lines with correct diameters Tubing is long enough for all connections Multiple exhaust filters Evaluate the bag film Connectivity Minimize the number of sterile connections Welding vs. sterile connectors Solution bags with on-board filters and tubing to match the SUB Raw Materials Liquid media Pre-made solutions (nutrient feeds if stability allows, glucose, glutamine, antifoam) Have capability to formulate if needed

Downstream Learning from Early Adoption Design Limitations Skids: flow rates, mixing, temperature control, hydroxide exposure, flow kit max usage time (limited tubing lifetime in peristaltic pump) mab throughputs: low chrom skid flow rates, low TFF membrane throughput Instrumentation Limitations Sensor (P, T, UV, flow, conductivity) issues Use of traditional ph probe instead of inline ph probe Installation Limitations Operators must standardize sensors as part of self check Manifold installation is cumbersome Lack of manifold labeling can result in cross connectivity issues Standard manifold tubing sizes may require different connectors (connecting 1 to ½ tubing) Tubing management and consumable design were key early learnings Need to manage customization against cost
Process Design Goals for HT, mab Facility Standardized offering All single-use equipment Medium/high density fed batch CHO (10 40 E6 cells/ml) Downstream to process a wide range of upstream titers Small (2 g/l), Medium (5 g/l) and Large (8 g/l) Downstream Scenarios One set of standard equipment with scaling flexibility Define closed processing needs and connectivity strategy Placement of unit operations for optimal suite scheduling and process flow Allowable process duration for each unit operation Off-the-shelf products wherever possible BOMs for small, medium, and large downstream Raw material and consumable costs for a batch
