Each individual 5cm ID GMP Run Ready column is labeled with the following 1. Catalog Number 2. Resin description 3. Lot number 4. Serial number
OPUS® Column Part Numbers OPUS® Column part numbers are structured so basic column configuration details can be deciphered. The OPUS® part number system, which is governed by QA-FM-10107, is not unique for all user specified inputs, and therefore an OPUS® Work Order is generated for every new purchase order even if the same column/part number is re-ordered. See Figure 2.5 for the OPUS® part number format. Figure 2.5 OPUS® Part Number Format
13
OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
If for example a customer were to order a 45 x 15 cm GMP Run Ready OPUS® R Column packed with Repligen-sourced CaptivA® resin, the part number would be, BC-450-CPRI-150-GR. The part number code works as follows:
The first 2 digits (“BC”) show the resin is Repligen sourced (vs. customer supplied)
The next 3 digits show the nominal column diameter in millimeters (“450”)
The subsequent 4 digits show the unique code for resin being packed (“CPRI”)
The next 3 digits show the target/specified bed height in millimeters (“150”),
The last 1 or 2 digits reference the GMP level (Pre-GMP or GMP Run Ready) as well as if the column configuration includes an OPUS® R port (“GR”)
2.4 Column Manufacturing and Packing
Obtaining User Specified Column Inputs
All OPUS® columns are manufactured using input from the OPUS® quote request form (https://www.repligen.com/rfq/), which documents user specified configurable product aspects such as,
Column details: internal diameter, bed height, resin source, GMP Level
Acceptance criteria (if specified): plate count, asymmetry, pressure vs. flow
Application specific (if specified): maximum working flow rate, maximum working pressure,
preferred storage solution
All fields on the OPUS® Quote Request form are filled in with input from the end user and/or a Repligen sales professional. The form is then submitted for review prior to the formal quoting process. Once a purchase order has been submitted and accepted against a formal quotation, an OPUS® Work Order is drafted by Repligen to formalize the user specified inputs contained in the quote request form. The Work Order is then sent to the customer for review and approval. Upon written approval from the customer, the OPUS® Work Order (QA-FM-10016) is finalized and the column/s is added to the manufacturing schedule. See Section 3 for more information on the OPUS® Work Order.
Resin Supply
When ordering an OPUS® column, the resin may be supplied by the customer, drop shipped from the resin manufacturer, or procured through Repligen. If the customer decides to source the resin and supply it to Repligen for column packing, then the Health and Safety Declaration for Accepting Customer Supplied Resin form (QA-FM-02-10035) must be completed. Overview of OPUS® Column Production Processes* Column Components: All incoming raw materials and custom components are subject to an incoming inspection procedure. Only the parts in compliance with the criteria set forward in the approved Raw Materials and Component Specifications documents are released for column assembly and packing. Resins: For all resins, Repligen maintains strict material controls including assignment of internal lot numbers to enable full traceability within batch records consistent with good documentation practices. The SOPs which govern these procedures are SOP-1094 (Control of Incoming Materials),
14
OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
SOP-10042 (Control of Incoming Components) and SOP-10035 (Customer Property). In addition, all resins are tested for identity (FTIR) prior to release for column packing.
Manufacturing Qualification: The column assembly processes are qualified and documented with appropriate SOPs and batch records as specified in Repligen’s ISO 9001 Quality Management System.
Preparation of Column Components: Column parts are washed and cleaned prior to assembly. Washing and cleaning procedures are qualified and validated.
Column Packing: OPUS® 5, 10 – 60/R cm ID columns are packed in a controlled, classified clean room that meets ISO Class 7 standards.
Quality Control: Each pre-packed column is individually tested according to the specifications detailed on the OPUS® Work Order. The specifications and the results of the release tests are documented on the Certificate of Analysis.
Packaging: Columns are secured by foam packaging material, and shipped in qualified shipping containers.
The OPUS® 5, and 10 – 30 cm columns are sealed in polyolefin bags in a controlled, classified clean room that meets ISO Class 7 NVP standards and then packaged in a cardboard box with foam packaging material. For OPUS® 10 - 30 cm columns, the box is strapped and shipped on a plastic pallet. See Sections 4 and 6 for more information.

Technical Documents: A variety of supporting technical documents, presentations, and videos can be found on Repligen’s website by visiting www.repligen.com/opus. CE-Certificate: EG directive 97/23/EG is not applicable for OPUS® columns, and therefore no columns will be CE-signed.
Performance OPUS® columns are designed to provide chromatographic performance equivalent to or better than traditional self-packed columns. The performance is attained through a semi-automated packing process and the design of the flow distribution system.
Optimal flow distribution is achieved through a flow distributor design with minimized dead
space volume. Rigorous Computational Fluid Dynamics (CFD) models validated by experiments
have provided evidence this flow distributor design is optimal for uniform radial distribution.
Mathematical modeling and performance testing have verified that the flow distributor design
provides chromatographic performance consistent with traditional columns.
Multi-cycle performance tests have shown that OPUS® columns deliver robust and reproducible
chromatographic results
Note: More information on column performance can be found on at www.repligen.com/opus. Ease of Use The OPUS® 5, 10 – 60/R cm ID platform design incorporates ease of use features such as lifting
handles, castors, and industry standard sanitary tri-clamp inlet and outlet connections (see Table for
more information).
Inlet/Outlet Port Locations The OPUS® 10-60/R column inlet and outlet ports are both located on the top side of the column.
The column inlet and outlet are secured with a tri-clamp fitting designed by SaniSure® to be both
leak-proof and tamper-evident.
The OPUS® 5 cm column design has inlet and outlet ports located at either end of the tube like a typical lab scale self-pack column design.

2.7 Column Stability Repligen conducted a study to assess shelf life stability for OPUS® columns when stored according to instructions in the user guide. Two different studies ran in parallel over an 18 month period:
Mechanical stability study: This study looked at the structural integrity of the column assembly at pre-determined time points over the course of 18 months.
Study design: Three columns of different internal diameters (10 cm, 20 cm, and 30 cm ID) initially filled with 18.5% EtOH solution up to a 20 cm bed height were pressurized to 4 bar and the pressure decay was monitored for 60 minutes. During the course of this pressure hold period, the column was visually inspected for gross failure such as leakage from ports and/or threads, and general structural integrity. See Table 2.6 for the mechanical stability test schedule and acceptance criteria. Results are summarized in Table 2.7.
Chromatographic performance stability study: This study looked at the chromatographic performance of the large scale columns over an 18 month period when stored at 2-8 Celsius. The goal of this study was to show no significant performance degradation will occur if a customer purchases a column and places it on the shelf for up to 18 months. Cold storage was deemed as “worst case” due to the polypropylene materials becoming more brittle in cold temperatures.
Study Design: Four 20 cm columns were packed with agarose resin to a 15 cm bed height. Acceptance criteria for the columns is summarized in Table 2.6 at “T=0.” One column was retested at each of the time intervals and compared with the performance of that specific column at time zero. The results are summarized in Table 2.8.

At the end of 18 months, bioburden for all 4 packed columns (serial numbers 0001 – 0004) was 0 CFU/ml and endotoxin for all 4 packed columns (serial numbers 0001-0004) was <0.1 EU/ml.
Cleanability
OPUS® Columns are used for purification of biological products which have specific regulatory
requirements for bioburden and endotoxin levels. Therefore, a quantitative cleaning investigation
was performed to demonstrate the effectiveness of sanitization using sodium hydroxide as a
cleaning agent.
Method: Several different OPUS® Columns were packed with Sepharose 6FF in 20 cm bed heights.
Each column was loaded with 1 column volume of E. coli bacteria at a concentration of 0.1 OD
(optical density) at 600 nm. The columns were left to incubate at ambient temperature overnight,
and then flushed with reverse osmosis deionized (RODI) water for 2-3 column volumes in down-
flow. Samples were collected to measure bioburden and endotoxin. A sanitization procedure was
subsequently used as followed:
Sanitization procedure: • Flush with 1 M sodium hydroxide in up-flow at 100 cm/h for 30 minutes
• Flush with 1 M sodium hydroxide in down-flow at 100 cm/h for 30 minutes
• Recirculation of 1 M sodium hydroxide for 2 hours in up-flow at 100 cm/h
• Incubation of the column in 1 M sodium hydroxide for 1 hour (static sanitization for compete
removal of endotoxins)
• Flush with RODI water at 100 cm/h until neutral pH is achieved
Each column was then left to incubate at ambient temperature overnight prior to pulling samples for
bioburden and endotoxin testing.
Results: Results for bioburden and endotoxin levels from the microbial challenge are outlined in the
table below, which shows the sanitization procedure completely removed bioburden from millions
of CFU to zero CFU in the post-sanitization water rinse. In addition, endotoxin levels were brought
below the limit of detection (0.25 EU/mL) for the assay.

Conclusions: In order to test effectiveness of sanitization on an OPUS® column, a worst case scenario was devised where the column was loaded with an excess of E. coli culture (a gram-negative, endotoxin producing bacteria). The results of the sanitization protocol demonstrate the effective removal of bioburden and endotoxin contamination.
2.7.1 Warranty
Repligen aspires to complete customer satisfaction, and has implemented the following warranty policy for OPUS® Columns.
If the column arrives at the customer site in damaged condition, Repligen will accept the damage risk and issue a replacement at no charge.
If the column fails passing specifications as agreed to on the OPUS® Work Order, Repligen will conduct troubleshooting efforts and if unsuccessful, will ask for the column to be returned for further evaluation. If the root cause of the failed test is determined to be a compromised packed bed, Repligen will pack a replacement at no charge.
If the column’s packed bed is compromised (i.e. a channel develops) and the root cause is packing, then Repligen will replace the column at no charge.
2.8 Material Safety Data Sheet OPUS® columns are made from plastic components only and therefore no MSDS is needed. An MSDS for the chromatography resin packed into an OPUS® Column may be obtained from the resin manufacturer.

3.5 OPUS® Column Manufacturing
Packing Environment and Environmental Controls All OPUS® columns are packed in ISO Class 7 classified clean rooms and buffers prepared in an ISO 8 classified clean room. The rooms are monitored on a weekly basis for viable contaminants using TSA settle plates. Microbial contaminants (bacteria) are counted and reported. Viable contamination limits have been set for the ISO 8 rooms as follows:
Alert Limit: > 20 CFU/plate Action Limit: > 35 CFU/plate
Viable contamination limits have been set for the ISO 7 rooms as follows: Alert Limit: > 10 CFU/plate Action Limit: > 25 CFU/plate Counts which exceed an alert or action limit are investigated according to SOP-MFG-1207.
The OPUS® manufacturing suite is monitored on a weekly basis for Non-Viable Particles (≥ 0.5 µm). Each room is monitored in predetermined locations, measuring 1 cubic foot of air over the course of 1 minute. NVP limits have been set for the ISO Class 8 clean room spaces as follows:
Alert Limit: ≥ 25,000 particles per ft3 (880,000 particles per m3) Action Limit: ≥ 50,000 particles per ft3 (1,760,000 particles per m3) ISO 8 Specification: ≤ 100,000 particles per ft3 (3,520,000 particles per m3)
NVP limits have been set for the ISO Class 7 clean room spaces as follows: Alert Limit: ≥ 2,500 particles per ft3 (88,000 particles per m3) Action Limit: ≥ 5,000 particles per ft3 (176,000 particles per m3) ISO 7 Specification: ≤ 10,000 particles per ft3 (352,000 particles per m3)

OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
OPUS® Work Order and User Specified Inputs Once a purchase order for a column has been received, the OPUS® Work Order (QA-FM-10015) is created. The OPUS® Work Order compiles information from the purchase order as well as the user specified inputs which were recorded from the OPUS® quote request form (https://www.repligen.com/rfq/). Note: All OPUS® columns are built to order and each column ordered must have a quote request form and unique Work Order. These forms document critical user specified inputs and therefore cannot be eliminated from the ordering process. In addition, each OPUS® Work Order is unique to a PO number and column part number. The OPUS® Work Order captures a variety of information including the following,
Quote number, purchase order number and column part number
Column size, type, and resin
Column packing method and solutions used
Column performance release method and specifications (ex: Asymmetry and plate count)
Revision history Once all required fields have been populated, Repligen sends the OPUS® Work Order to the appropriate customer contact for review. If all the details in the document are satisfactory, the customer signs and dates the form, and then sends the signed form back to Repligen. Once the signed form is received, Repligen can begin column packing. Note: Column packing cannot begin without a customer approved work order. See below for an example of the OPUS® Work Order. Figure 3.1 OPUS Work Order Example (blank)

OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
Chromatography Resin Control All chromatography resins are tested for identity using FTIR prior to being released for production. A copy of the FTIR spectrum is maintained with the completed batch record. The SOPs governing chromatography resin control procedures are SOP-1094 (Control of Incoming Materials), SOP-10042 (Control of Incoming Components) and SOP-10035 (Customer Property).
Repligen Supplied Resins Resins purchased and supplied by Repligen for column packing are controlled as a raw material according to SOP-1094 (Control of Incoming Materials). Upon arrival, each resin is placed into quarantine pending disposition by Repligen Quality assurance. Upon release, each batch of resin is given a unique internal lot number and expiration date to ensure full traceability throughout the manufacturing process. Customer Supplied Resins Repligen’s customer property procedures (SOP-10035) are designed to protect our customer’s financial and intellectual property interests to prevent unauthorized use, disclosure, or disposal. All resins shipped to Repligen for column packing must be unused. Each customer supplied resin is assigned a unique customer property number which is typically linked to a specific purchase order and part number. The customer property number is noted on the form entitled, Health and Safety Declaration for Accepting Customer Supplied Resin, which must be filled out by an end user prior to shipping resin to Repligen. Upon arrival, the resin is managed according to SOP-10035, which dictates the resin must be labeled, segregated, and then stored according to the resin vendor’s recommendation. All customer supplied resin is also tested for identity using FTIR prior to being released for production. Unused media is either returned or discarded according to the customer’s instructions.
Repligen understands in some instances customers may have a requirement to sample and test a small aliquot of the resin for identity (ex. FTIR). Unused resin in containers, which have been sampled for QC testing, are compatible with Repligen’s quality requirements and therefore can be accepted for column packing.
Resin Preparation Once the appropriate resin has been released, parts cleaned, and column packing batch record documentation have been issued, the follow steps occur: 1. Manufacturing operators move sealed resin containers into one of the OPUS® ISO 7 clean
rooms. Note: only the released resin is allowed in the packing room, and only one resin type at a time can be present.
2. Manufacturing operators verify the appropriate resin by checking against the OPUS® Work Order.
3. After verifying the resin, containers are opened for resin preparation (decantation of storage solution, fines removal, etc.).
4. For OPUS® GMP Run Ready columns only, prior to beginning resin prep an operator removes 10-30 mL of resin per resin lot from the original container. This operation is performed using a sterile pipette and the operator dispenses the resin aliquot into a 60 mL gamma irradiated, tamper evident PETG (polyethylene terephthalate) bottle. The bottle is then sealed and labeled with resin name, lot number, part number, date, and Repligen operator initials. In the event multiple resin lots are packed into a single column, a single side sample of each resin lot will be taken. Therefore, multiple side samples will be delivered with a GMP Run Ready column if multiple resin lots are packed.
32
OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
5. After column packing, the resin “QC sample/s” or “resin side sample/s” are stored with the finished the OPUS® GMP Run Ready column for shipment.
In general, Repligen uses the following approach for slurry preparation and percent solids determination: 1. Decant off storage solution 2. Perform defining of resin as specified by resin MFG. 3. Suspended resin in packing buffer to target the desired % solids 4. Combine resin bottles in a holding tank if required 5. Pull resin samples 6. Record mass and volume added for density calculations 7. Spin samples in a centrifuge 8. Read spin down solids volume 9. Determine average % solids (solids vol. / total vol.) 10. Use target compression factor (CF = target column vol./uncompressed resin vol.) as derived by
a. Past empirical data b. Resin manufacturer recommendations c. Repligen R&D recommendations
11. Calculate target solids volume to add (target bed volume / CF) 12. Apply % solids (Step 9) and density (Step 6) to target solids calculations (Step 11) to determine
mass of slurry required 13. (Target solids vol. / % solids) * density = mass slurry to dose Assembly, Packing, and Performance Testing OPUS® columns are assembled from qualified and controlled components. Inspected and released component parts are taken from inventory and brought into the ISO 8 classified cleanroom through an automated parts washer. Parts which do not enter through the parts washer are chemically cleaned with NaOH, followed by rinse with RODI water to depyrogenate and reduce bioburden. Both processes have been qualified and validated to the following specifications:
Table 3.2 Parts Cleaning Specifications
Method Parts Cleaning Specifications
Bioburden Endotoxin TOC Conductivity pH
Parts Washer < 10 cfu/ml < 0.5 EU/ml < 10 PPM < 10 uS/cm 5.0 – 7.0
NaOH Soak < 10 cfu/ml < 0.25 EU/ml N/A < 50 uS/cm 5.0 - 7.0
The following points summarize the major steps which occur during OPUS® Column packing: 1. Solutions and buffers are prepared in the ISO 8 area of the OPUS® clean rooms. All buffers and
solutions are filtered with a 0.2um filter. 2. Packing solutions/buffers and allocated parts, which have been cleaned, are brought into the
designated ISO 7 packing room. 3. All subsequent steps are performed in the designated ISO 7 clean room. 4. The bottom flow distributor with the ultrasonically welded mesh is inserted into the bottom end
of the tube to form a water-tight seal. The flow distributor assembly is then secured in place with a polypropylene weld or adhesive bond.
33
OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
5. The chromatography resin is added to the open ended column by dosing directly into the column or using a peristaltic pump.
6. The top flow distributor is inserted into the column tube and packing is initiated to establish a uniform bed. OPUS® columns utilize flow packing, axial compression, and/or a combination of both methods to achieve a well packed bed. In general, packing protocols are developed in Repligen’s R&D department and subsequently transferred to the production team.
7. Following the prescribed packing procedure, the top flow distributor is precisely positioned to create the correct resin compression. Note: Rigid particle resins such as ceramic hydroxyapatite are not compressed, rather the top flow distributor is positioned so there is no significant gap between the consolidated resin bed and the flow distributor assembly.
8. Bed performance is tested according to the procedure and specifications as documented on the OPUS® Work Order. Note: A column may be tested and flow distributor adjusted during the packing process to ensure optimal performance.
9. Once the final flow distributor position is set and the column has met the performance specifications (theoretical plates/meter and Asymmetry) as documented on the OPUS® Work Order, the packing process can conclude.
10. The column is then sanitized using a procedure recommended by the resin manufacturer and/or as documented on the OPUS® Work Order.
11. Post sanitization, the column is then neutralized (typically with RODI water), and Bioburden or Endotoxin samples taken (OPUS® GMP Run Ready Columns only).
12. After neutralization, each pre-packed column is put in its final storage solution as documented on the OPUS® Work Order.
13. The column assembly is then finished by securing the flow distributors in place using a polypropylene weld or adhesive bond, and assembling the top cap, bottom cap, and side-guard. Note: The top cap, bottom cap, and side guard serve cosmetic and ergonomic functions, and therefore do not impact the performance of the column.
14. Inlet and outlet ports are capped and sealed using a tamper evident SaniSure clamp. 15. Each OPUS® 5, 10 – 30 cm Column is sealed in a polyethylene bag before being removed from
the OPUS® cleanroom suite. Note: OPUS® 45/R and 60/R cm Columns are not bagged since they are on wheels.
16. Columns are then stored according to storage conditions as noted on the OPUS® Work Order.
Client resin verification upon arrival: Included with each column lot is a copy of the resin vendor’s Certificate of Analysis1 and a small sample/s (10-30 mL) of resin (GMP Run Ready columns only) intended for incoming quality control analysis. As described above, in the event multiple resin lots are packed into a column, a resin aliquot is taken for each resin lot and delivered with the column. Finally, the column label contains the resin description, and the certificate of analysis for each column indicates the part number and lot number of the pre-packed resin.
Equipment Used in the Manufacturing of OPUS® Columns: Wherever possible, all equipment used to pack OPUS® columns is dedicated single use equipment such as:
Slurry tanks and carboys
Single-use liners for buffer tanks
Single-use platinum cured tubing for pipe transfers
1 In rare cases a resin vendor’s certificate of analysis may not be included with the OPUS CoA package. For
example, when a customer ships custom resin without a CoA to Repligen for packing, Repligen may not be able to include a resin CoA in the OPUS CoA package if the custom resin CoA is not readily available from the manufacturer.

Where reusable components are used in the manufacturing process which might come into contact with the resin or the inside of the column, Repligen employs validated cleaning protocols to ensure the risk of cross resin “contamination” is mitigated.
3.6 Bioburden and Endotoxin Release Testing Columns are tested according to the specifications detailed in the OPUS® Work Order. Bioburden and endotoxin testing is performed on OPUS® “GMP Run Ready” columns and samples are taken in RODI water post sanitization and just prior to introducing the storage solution. The release specifications are as follows:
Bioburden: <10 CFU/mL
Endotoxin: <0.25 EU/mL Repligen performs endotoxin and bioburden testing in-house using the following two methods. Bioburden assay method Bioburden is analyzed by a vacuum filtration method. The sample is applied to a sterile filter under vacuum and then rinsed with peptone water. The filter is collected aseptically and placed onto TSA media. The plate is placed into an incubator at 32C +/- 2C for 5 days. An analyst reads the plates at day 3 and day 5 and documents the results. A negative control of the peptone water is also plated and incubated to demonstrate the reagents used during the analysis were not contaminated. Endotoxin assay method Endotoxin is analyzed by gel clot method. Repligen uses a commercially available kit and performs the test according to the manufacturer’s instructions which have been transcribed into an internal test procedure. A column rinse sample with a volume of 0.25 mL is introduced to the gel clot tube and incubated in a 37C water bath. The tubes are then read by an analyst and the data is recorded. A positive control is run alongside the sample for this assay. Bioburden and Endotoxin test results are documented on the Certificate of Analysis as a pass/fail result for each GMP Run Ready column. See Section 2.0 for sample CoA documents. Note: OPUS® Pre-GMP columns are not tested for bioburden or endotoxin.

4. Shipping Qualification
4.1 Summary
To certify the packaging, column components, and column performance remains intact during and after shipping, International Safe Transit Association (ISTA) tests were conducted on a variety of OPUS® column sizes. A third party certified laboratory performed the shipping tests, and Repligen tested chromatographic performance pre and post shipping. Results from the studies show the packaging withstands the stressors of commercial shipping, and chromatographic performance is maintained.
4.2 Introduction Objective The objective of the shipping studies is to demonstrate the custom made packaging (Figures 5.1 and 5.2) and pre-packed columns of multiple diameters arrive intact after worst case shipping simulations. See Section 6 for engineering drawings of packaging used for each internal diameter column. OPUS® columns employ different packaging based on size and weight. To cover the range of different column dimensions and packaging methods/materials the following column sizes were evaluated.
OPUS® 5 cm Column
OPUS® 10 cm Column (uses identical packaging as the OPUS® 14 cm Column)
OPUS® 20 cm Column (uses identical packaging as the OPUS® 25, and 30 cm Columns)
OPUS® 45 (uses identical packaging as the OPUS® 45R Column)
OPUS® 60 (uses identical packaging as the OPUS® 60R Column)

Acceptance Criteria The shipping tests documented in this regulatory support file have two different acceptance criteria categories as detailed below.
Visual inspection of packaging Per ISTA guidelines, procedures 2A and 2B call for a simple pass/fail assessment based on a visual test of packaging materials. This assessment is made by the certified ISTA test facility and documented in a summary report.
Chromatographic performance Repligen assessed chromatographic performance by measuring plate count and asymmetry to compare “pre-shipping” performance with “post-shipping” performance. In order to pass the chromatographic portion of the test, the minimum post-shipping theoretical plate count and asymmetry measurements had to be within +/-25% of pre-shipping results.

4.3 Method: ISTA 2A and 2B Tests
4.3.1 ISTA Test Methods
ISTA Procedure 2A was used for the OPUS® 5 cm ID and 2B2 was used for OPUS® 10 – 60/R cm IDs. The selection of the two tests has to do with weight and shipping methods (see below).
ISTA Procedure 2A is a worst case simulation test for individual packaged-products shipped in boxes (“parcel shipments).
ISTA Procedure 2B is a worst case simulation test for individual packaged-products shipped on pallets
Both tests are used to:
Evaluate the performance of a packaged product
Compare relative performance of the package and product design
During the test, the package and product are considered together and not separately.
Tests and Conditions All studies were performed by Atlas Box and Crate in Sutton, MA per ISTA guidelines. The specific test conditions are described further in Table 5.1 below. The 5, 10, 20, 45, 60, and 60R columns were manufactured by Repligen, packaged into their respective shipping containers, picked up by Atlas, shipped to their certified testing facility, and tested according the applicable standards. After the tests were complete, Atlas returned the shipping containers to Repligen for post testing analysis.

4.3.5 Conclusion
In summary, the following was observed post worst case shipping simulation:
No significant damage to the shipping containers
No damage to the column structures
No discernable damage to the packed beds

5. Extractables and Leachables
5.1 Introduction and Background
Plastic materials have been used in the manufacturing of therapeutics for many decades. Over the last 15 years, focused product development by many vendors and biotechnology companies has resulted in a plethora of single-use technologies. During this time, the industry has witnessed the development and adoption of critical disposable and single-use technologies like mixers, bioreactors, filters, and connectors. As a result, standards and best practices for evaluating component safety have been set for the selection and qualification of plastics.
In general, plastics used in biopharmaceutical manufacturing have low defined extractables and have been determined to be non-toxic at equivalent therapeutic doses. Many base standards used for guidance have been set by regulatory publications including USP, CFR 21, and EMEA. These basic standards have been elaborated on by industry organizations like the Bio-Process Systems Alliance (BPSA) and Parenteral Drug Association (PDA) as well as product manufacturers through the publication of best practices of testing and assessment of data. In addition, end user therapeutic manufacturers have become more demanding in their analytical requirements, assessment of data, determination of risk, and minimum threshold for meeting internal standards.
Repligen is sensitive to the demands of the industry and will therefore supply relevant and applicable information about the plastics used in the product contact components of OPUS® columns. In accordance with industry standards, Repligen uses the definitions for extractables and leachables as stated in the 2007 BPSA document, "Recommendations for Extractables and Leachables Testing: Part 1.”
Extractables: Chemical compounds that migrate from any product-contact material when exposed
to an appropriate solvent under exaggerated conditions of time and temperature.
Leachables: Chemical compounds, typically a subset of extractables that migrate into a drug
formulation from any product contact material as a result of direct contact under normal process
conditions.
There is a general consensus that it is the responsibility of the product technology vendor to provide an extractable data package. In recent years there have been efforts to standardize the testing procedures for extractables, and wherever possible it is Repligen’s intent to comply with the standardization efforts. In addition, in compliance with CFR 21, Part 211.65, OPUS® columns are designed such that all product contact materials are not reactive, additive, or absorptive so as to alter the safety, identity, strength, quality, or purity of the drug product beyond established requirements.
Therefore, using the BPSA guidance as a backdrop, Repligen has designed an extractables program to produce a robust data package by conducting extractables testing using three solvents as well as exaggerated time and temperature conditions. Solvents were chosen for their common usage in chromatography columns. Leachables, however, are considered to be process specific and the responsibility of the end user to define within specific process parameters.

OPUS® 5, 10 – 60 cm, OPUS® R Columns Regulatory Support File
5.2 OPUS® Extractables Strategy Based on the above discussion, Repligen has applied the following philosophy in its approach to developing a meaningful extractables and leachables package for OPUS® columns:
1. All plastics used will be certified to meet four criteria (see Sections 3.2.1–3.2.4 for more detail):
a) Certified to meet USP <88> Biological Reactivity Tests, In Vivo (USP Class VI) b) Certified to meet CFR 21 Part 177 Indirect food Additives: Polymers
i. Sec. 177.1520 Olefin polymers (Polypropylene) ii. Sec. 177.2600 Rubber articles intended for repeated use (Silicone)
c) USP General Chapters 661: Polypropylene Containers d) Certified Animal Free or compliant with EMEA 410/01
2. Extractables from the OPUS® 5, and 10 – 60/R cm Column platform were determined according
to an approved written experimental rationale for exaggerated time and temperature conditions
and tested against an approved protocol.
3. Leachables from the OPUS® 5, and 10 – 60/R cm Column platform: Repligen will not conduct,
nor present data for leachables in this Regulatory Support File for any process specific solution
beyond what is determined in the extractables testing. Repligen will on request, support client
based leachable testing by providing component test materials.
5.3 USP<88> Biological Reactivity Tests, In Vivo Six plastic classes are defined in Table 3.1. This classification is based on responses to a series of in vivo tests for which extracts, materials, and routes of administration are specified. These tests are directly related to the intended end-use of the plastic articles.

Acute Systemic Toxicity Test Purpose: In-vivo systemic tests evaluate the impairment or activation of a system rather than the impairment of individual cells or organs. In “acute” systemic toxicity tests, the test material (extract) is tested for systemic toxic effects as a result of a single, acute exposure. This test is designed to evaluate systemic responses to the extracts of materials following injection into mice.
Irritation Test: Intracutaneous Irritation Test
Purpose: The irritation tests are in-vivo screening tests to evaluate the potential of test materials or their extracts to cause irritation on the exposed part of the body. This test is designed to evaluate local responses to the extracts of materials following intracutaneous injection into rabbits.
Implantation Test: Intramuscular Purpose: Implant studies evaluate the local pathological effects on living tissue at both the gross and microscopic level of a test article surgically implanted into an appropriate implant site. The implantation test is designed for the evaluation of plastic materials and other polymeric materials in direct contact with living tissue.
5.3.1 CFR 21 Part 177 Indirect food Additives: Polymers
Subpart B: Substances for Use as Basic Components of Single and Repeated Use Food Contact Surfaces. Section 177.1520 – Olefin Polymers (Applied to Polypropylene). The olefin polymers from polypropylene referenced in CFR 21 Part 177 Sec. 177.1520 may be safely used as articles or components of articles intended for use in contact with food, subject to the provisions of this section. Subpart C: Substances for use only as components of articles intended for repeated use Sec. 177.2600, and rubber articles intended for repeated use (applied to silicone). Rubber articles intended for repeated use may be safely used in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food, subject to the provisions of this section.
5.3.2 USP General Chapters 661: Polypropylene Containers
The standards and test provided in this section characterize polypropylene containers produced from homopolymers or co-polymers that are suitable for packaging dry solid or liquid oral dosage forms.
5.3.3 Animal Free and EMEA 410/01
Note: This is for guidance on minimizing the risk of transmitting animal spongiform encephalopathy agents via human and veterinary medicinal products. Scientific principles for minimizing risk (EMEA 410/01): Use of materials from ‘non TSE-relevant animal species’ or non-animal origin is preferred. If materials from ‘TSE-relevant animal species’ have to be used, consideration should be given to all the necessary measures to minimize the risk of transmission of TSE.

5.4 Extractable Test Protocol and Results
By Michael Ruberto, Ph.D.
Background Repligen has performed polymer deformulation and extractables testing on the product contact components of their OPUS® columns. This data has been consolidated into a format that will be suitable for use in the OPUS® product literature. Extractables and Leachables Materials The materials used to fabricate single-use processing equipment for biopharmaceutical manufacturing are often polymers, such as plastic or elastomers (rubber), as opposed to the traditional metal or glass. Polymers offer more versatility, since they are light-weight, flexible and much more durable than their traditional counterparts. Plastic and rubber are also disposable, so issues associated with cleaning and its validation are often avoidable. Whenever there is contact between a material of construction for a manufacturing component and therapeutic, there is always the possibility for chemicals from the material to migrate or leach into the drug. All materials can produce leachables. Leachables are the chemicals that migrate from single-use processing equipment into the various components of the drug product during manufacturing. Extractables are chemicals entities, organic and inorganic, that can be extracted from single-use processing equipment using common laboratory solvents in controlled experiments. They represent the worst case scenario and are used as a tool to predict the types of leachables that can be encountered during pharmaceutical production. So, extractables are the “potentials” and leachables are the “actuals.” An effective way to minimize and control leachables is to use well characterized materials to fabricate the manufacturing equipment. The OPUS® column product contact materials are mainly constructed from polypropylene (PP) homopolymers and platinum cured silicone. PP homopolymer is much less prone to leachables than other types of polyolefins due to its mechanical and physical properties (such as melting point, glass transition temperature, molecular weight distribution, and percent crystallinity.) All of these important polymer characteristics have been measured and benchmarked for each PP product contact component and can be used as a quality control measure to ensure that all incoming raw materials have similar properties. This can help to ensure consistent, batch-to-batch leachables profiles for the OPUS® product contact components. The additives package has also been determined for each polymer in an effort to predict and control leachables. The platinum cured silicone components are very durable materials that are often used in medical applications. These silicone elastomers are amorphous polymers that usually do not require formulation with additives such as phthalates, antioxidants, or heat and light stabilizers. This less complex formulation greatly reduces the risk of leachables. The silicone polymers have also been fortified with silica fillers to provide the essential mechanical properties required for the OPUS® chromatography applications. As in the case of the PP components, the mechanical and physical properties of the platinum cured silicone gaskets and tubing have all been measured and benchmarked. All polymers used to construct the product contact components have met the requirements of a USP Class VI polymer and are regulated for food contact application according to 21CFR Part 177 Indirect Food Additives. The specific polymer and regulatory information is summarized in the table below.

Testing The polymers utilized in medical and pharmaceutical applications should be compliant with the appropriate USP guidelines and it is recommended that they meet the USP Class VI testing requirements. The appropriate extractables and leachables (E&L) testing programs should be implemented for the bioprocessing materials that come into direct contact with components of the drug formulation. Three industry groups have published “Best Practices” for conducting this testing. Several presentations and publications were prepared by the Product Quality Research Institute (PQRI) for the evaluation and safety assessment of extractables and leachables in packaging for various drug dosage forms of high risk. These recommendations apply to the primary and secondary packaging associated with these pharmaceutical products. The BioProcess Systems Alliance (BPSA) and BioPhorum Operation Group (BPOG) have also published technical guideline for evaluating the risk associated with extractables and leachables specifically for single-use processing equipment.
The Repligen approach to E&L testing is that it is the responsibility of the product technology vendor to provide a technical extractable package. Leachables, on the other hand, are considered to be process specific and the responsibility of the end user to define with specific process solutions. With that in mind, Repligen has designed an extractables program to produce a robust data package by conducting extractables testing using three solvents under exaggerated conditions of contact. The materials of contact in the OPUS® Column platform:
Extruded PP (5, and 10 – 30 cm tubes only)
Polypropylene / E-Glass Composite (OPUS® 45/R – 60/R cm tubes only)
Machined Compression Molded PP
Polypropylene Mesh
Platinum Cured Silicone O-Rings
Platinum Cured Silicone Braided Tubing
Each were extracted with USP Water, 20% Ethanol, and 2.2% Benzyl Alcohol for 72 hours at 40oC. The extracts were analyzed for semi-volatiles by GC/MS, non-volatiles by LC/PDA/MS, and inorganics by ICP-MS. In addition, the neat OPUS® components were analyzed for volatiles by Headspace GC/MS. The data generated from this comprehensive series of extractables testing is detailed below.

5.4.7 Conclusions
The product contact materials used in OPUS® pre-packed chromatography columns meet the requirements of a USP Class VI plastic and are regulated for food contact applications. Each polymer has been hand selected based on its mechanical / physical properties, inherent stability, and low potential risk for leachables. Only those polymer additives that are functionally necessary are present in the OPUS® product contact components. This has been confirmed experimentally through a complete quantitative analysis of the additives package in each polymer. Extractables testing has been conducted for the product contact components using conditions of 40ºC for 72 hours in three solvents: USP water, 20% ethanol, and 2.2% benzyl alcohol. The extracts were analyzed for volatiles, semi-volatiles, non-volatiles, and metals. The identified extractables were correlated back to their source of origin in the OPUS® component so that they can be controlled during manufacturing. Structure elucidation was performed on the unknowns and empirical formulae were proposed when possible. The physical properties of the polymers that have the most influence over leachables (such as melting point, glass transition temperature, percent crystallinity, and molecular weight distribution) have been benchmarked to ensure a consistent batch-to-batch leachables profile for these components and a well-managed supply chain for raw

materials used in their construction. The result is a chromatography column which has achieved a minimization and control of leachables through comprehensive material characterization, quality control, and extractables testing.
5.5 Leachables: OPUS® Column Strategy The extractables information in this regulatory support file is designed to be the foundation of a leachable substances therapeutic safety assessment. The data presented represent an extractables profile of what might be extracted from an OPUS® Column under extreme exaggerated conditions (prolonged exposure at high temperature).
Role of the End User Each process is different, and therefore must be evaluated for impact of leachables. In many cases, the data provided by an extractables test can be used to create a risk based assessment to support a leachables program.
Role of Repligen Repligen will provide suitable component test materials and upon request to support application and process specific leachables testing.
5.6 Considerations for Leachables Testing Purpose To assess the safety risk posed to patients through exposure to low levels of chemical entities extracted from plastics in the manufacturing process.
Role of the “model solvent” extraction test In general, the model extraction vehicles in a standard extractables test will likely show all of the materials which could possibly be extracted from a plastic product. Model stream extraction vehicles are chosen for their ability to extract compounds from plastics as well as their relevance to the test application (chromatography in this case). The results of extractable tests can be compiled and analyzed to create a risk based approach for conducting (or not conducting) a leachables study.
Chromatography: An assessment of application impact In the case of chromatography the method from start to finish should be considered, however, a risk analysis should focus on the elution fluid, which in most cases will be an aqueous solution. Although a pre-packed chromatography column will see solvents such as 0.5N NaOH, phosphoric acid, high and low pH additives, and high salt conditions, in general none of these compounds or additives are meant to pass into the final product pool. In addition, impact to the final product pool is limited due to multiple chromatography or filtration steps which help to eliminate extractables throughout a typical downstream process. Therefore, to assess the impact of other solvents in addition to the elution solvent, extractables and leachables studies can be carried out with the proposed purification methods in mind. This will enable a thorough understanding of the impact of the chromatography steps as it pertains to leachables in the final product pool.
