EXECUTIVE SUMMARY OF ICH GUIDELINES Q5A (R1) AND Q4B ANNEX 2 (R1)
VIRAL SAFETY EVALUATION OF BIOTECHNOLOGY PRODUCTS DERIVED FROM CELL LINES OF HUMAN OR ANIMAL ORIGIN – Q4B ANNEX 2 (R1):
This document is concerned with testing and evaluation of the viral safety of biotechnology products derived from characterized cell lines of human or animal origin. The scope of the document covers products derived from cell cultures initiated from characterized cell banks. It covers products derived from in vitro cell cultures, recombinant DNA – derived products and also includes products derived from hybridoma cells grown in vivo.
Three principal approaches have evolved to control the potential viral contamination of biotechnology products:
a) Selecting & testing cell lines and other raw materials, including media components, for the absence of undesirable viruses which may be infectious and/or pathogenic for humans.
b) Assessing the capacity of the production processes to clear infectious viruses.
c) Testing the product at appropriate steps of production for absence of contaminating infectious viruses.
The guideline suggests approaches for the evaluation of the risk of viral contamination and for the removal of virus from the product. Following are the recommended tests for the brief description of a general framework and philosophical background within which the manufacturer should justify the testing that was done;
1) Test for Retroviruses
2) In vitro Assay

Summary
Medical devices are regulated by the National Medical Product Administration (NMPA), formerly the China Food and Drug Administration (CFDA)
Manufacturers must register their devices with the NMPA before selling or distributing in China.
The NMPA reviews all device applications and has strict requirements for submission documentation, testing, and clinical data.
Any instrument, apparatus, appliance, material, or other article whether used alone or in combination, including the software necessary for its proper application.
Diagnosis, prevention, monitoring, treatment or alleviation of disease
Diagnosis, monitoring, treatment, alleviation of compensation for an injury or handicap conditions
Investigation, replacement or modification for anatomy or a physiological process
Control of conception
The Chinese authorities (CFDA/NMPA) have their own quality management system requirements.
However, these “GMP requirements” are very similar to ISO 13485.
Therefore, manufacturers usually submit the ISO 13485 certificate.
However, the audit will review this certificate against the Chinese GMP requirements.
These audits are regularly carried out during the approval procedure and/or after a recall.
NMPA issued and implemented the "Guideline on Inspection of Quality Management System for Medical Device Registration" on October 10, 2022.
Product Life-cycle Process
The guideline specifies the basic requirements for registration inspection, self-inspection, commissioned inspection, and extended inspection, etc. Applicant needs to:
Ensure the design, development, production, and other process data to be true, accurate, complete, and traceable, and consistent with the registration application materials.
Carry out the registration QMS inspection in reference to the registration application materials, and focus on the design, development, procurement, production management, and quality control of the product.
For lower-risk medical devices (Class I and Class II), clinical evaluation may not always be required. However, higher-risk devices (Class III and implantable devices) generally require clinical evaluation.
The evaluation involves reviewing existing clinical data, scientific literature, and relevant clinical research to assess the safety and performance of the device.
All clinical trials for medical devices must follow China Good Clinical Practices
Clinical investigations are required if no equivalent devices can be found and safety and efficacy cannot be proven with other clinical and non-clinical data.
For certain medical devices, the NMPA may require clinical investigations, especially for novel devices or those with significant risk.
Clinical investigations involve conducting studies on human subjects to generate clinical data on the safety and effectiveness of the device.

Japan Medical Device Regulatory Approval ProcessKate Jablonski
Before deciding to sell your device in the Japanese market, it is important to understand how the regulations apply to your device, which steps to take, and what resources are required to complete the process. In this presentation, Ann Marie Boullie, Vice President of Business Development for EMERGO, outlines some of the most complex aspects of the Japanese registration process, including:
JMDN codes: device classification and predicates
Clinical data requirements and PMDA pre-submission meetings
Registration routes (Todokede, Ninsho, Shonin)
QMS (Ordinance 169) requirements
Role of the Marketing Authorization Holder (MAH)
Promises and Challenges of Manufacturing and Testing Viral Producer Cell LinesMerck Life Sciences
To date, manufacturing of lentivirus (LV) vectors for gene therapy commonly relies on transient transfection of adherent HEK293 cells. This method is costly, time-consuming, difficult to scale-up and poorly reproducible, rendering large-scale applicability to fulfill increasing demand of LV in clinical pipelines cumbersome. The use of suspension-adapted transient producer cell lines for LV production has overcome some of these challenges. Furthermore, successful creation of stable producer cell lines would allow creation of master and working cell banks easily amenable to commercial production. The ideal producer cell lines should demonstrate stability in growth and gene expression, and be easily adaptable to chemically defined culture conditions and optimized for high-titer virus production. The availability of more robust producer cell lines thus represents an important scalable first step towards manufacturing processes that are conducive to large-scale production. Ultimately, these producer cell lines must be screened to satisfy various biosafety and regulatory implications.
In this webinar, you will learn:
• Process development for transient and stable producer cell lines
• Screening of cellular gene targets via CRISPR to improve LV production from producer cell lines
• cGMP and Regulatory readiness: Cell line characterization and release testing through BioReliance® global service offering
In the month of February 2014 US Food and Drug Administration Commissioner Margaret Hamburg visited India to discuss issues of drug quality with her counterparts in the Indian Government. The FDA has imposed a rash of regulatory sanctions on Indian generic makers in the last year, triggering concerns about the quality of the medicines supplied by the $14 billion industry to countries including the United States, the biggest market. India is second only to Canada as a drug exporter to the United States, where it supplies about 40 percent of generic and over-the-counter drugs.There were comments made about the US and Indian GMP Standards. Drug Regulations has now compared the GMP standards of US and India. The comparison is given in the presentation here.

New European Medical Device Regulations: Keeping Your Orthopaedic and Spine ...April Bright
For years, notified bodies and industry experts have warned orthopaedic device companies to prepare for the forthcoming EU Medical Device Regulation (MDR). Though the regulation is expected to be officially published in the first half of 2017, a recent study shows that not only are companies not prepared, but regulatory and quality affairs professionals say that they have not studied the regulation closely.
The regulation includes new requirements for orthopaedic (and especially spine) companies that must be met in a timely manner to keep products on the market. Among the MDR changes are more stringent clinical evidence, identification of a “qualified person,” implementation of UDI and rigorous postmarket oversight.
Dr. Li covers highlights of the regulation and the provided transition period toward fulfillment of the new expectations. He explains the impact of device up-classification and the need for additional clinical data toward passing this new regulation successfully and toward fulfilling the postmarket reporting requirements accordingly.
How to Prepare for the New EU Medical Device Regulations (MDR)Greenlight Guru
The new MDR is expected to be formally published in late 2016 or early 2017, and there will be a three-year transition period to be compliant.
Many forward thinking medical device companies are already developing their plans for compliance now to gain strategic advantages over their competitors.
In this presentation you will learn:
-Why the European regulations are changing
-An overview of the text being voted on
-What does the new regulation mean for manufactures
-Examine the risk based approach to classification
-Strategy for technical documentation preparation

Use of rapid quality control test methods as alternatives to traditional meth...Merck Life Sciences
Abstract:
As the market for advanced therapy medicinal products (ATMP) matures the complexities of these molecules are evident and challenging when routine standard quality control (QC) testing is applied. Short shelf life from the point of manufacture to administration to the patient results in relatively low volumes for small scale clinical trials or small patient populations. Within a limited time period and with this low product volume, it is necessary to complete required regulatory QC testing, be that for early or late phase clinical trials, or for licensed drug product in a reduced timescale. So, the challenges with QC testing of cell and gene therapies using traditional test methods is time to results, due to short shelf-life, and availability of sufficient sample, due to low production volumes. Over the past years the application of rapid testing of short-life cell and gene therapies that may also help conserve limited product availability have been utilised. Regulatory expectations for using rapid test methods in place of classical or compendial test methods have been defined and this presentation will provide examples and data from our own experience of a range of alternate methods for application to ATMP products.

The Viscosity Reduction Platform: Viscosity-reducing excipients for improveme...Merck Life Sciences
Protein viscosity is a major challenge in preparing highly concentrated protein formulations suitable for subcutaneous injection. Recently, the Viscosity Reduction Platform (VRP) was introduced and its technical key features and benefits for formulations were discussed. However, highly viscous solutions do not only pose a challenge when administering a drug to a patient, they can also impose technical limitations in the manufacturing process.
This white paper evaluates the effect of the excipients in the Viscosity Reduction Platform on ultrafiltration processes used to produce a highly concentrated formulation of a monoclonal antibody (mAb). Two filtration methods are demonstrated in this work.

Use of Excipients in Downstream Processing to Improve Protein PurificationMerck Life Sciences
Excipients are used to improve the stability of protein-based therapeutics by protecting the protein against a range of stress conditions such as temperature changes, pH changes, or agitation. Similar stresses are applied to proteins during downstream purification. Shifts in pH during Protein A chromatography, subsequent incubations at low pH for virus inactivation, and changes in conductivity in ion exchange chromatography can lead to aggregation, fragmentation, or other chemical modifications of the therapeutic protein. Given the potential impact on the protein’s structural integrity, there is a need for approaches to reduce the risk presented by the conditions during downstream processing. For example, integration of a solution to prevent aggregation of proteins would be a more efficient strategy than implementing steps to remove multimeric forms.
This white paper highlights the results from a recent paper by Stange et. al., in which protein stabilizing excipients such as polyols, sugars, and polyethylene glycol (PEG4000) were used as buffer system additives. Effect of the excipients on elution patterns, stabilization of the monomer antibody, host-cell protein removal, virus inactivation rates and binding capacity of cation exchange chromatography were explored.
Exploring the protein stabilizing capability of surfactants against agitation...Merck Life Sciences
Agitation of therapeutic protein solutions during manufacturing, shipping and handling is one of the major initiators for protein aggregation and particle formation during the life history of a protein drug. Adsorption of protein molecules to liquid-air interfaces leads to the formation of highly concentrated protein surface films. The rupture of these protein films due to various mechanical processes can then result in the appearance of protein aggregates and particles in the bulk solution phase.
One technique to stabilize proteins against stress induced by liquid-air interfaces is the use of non-ionic surfactants. About 91% of antibody formulations commercially available in 2021 contained a surfactant. Polysorbate 20 and 80, composed of a hydrophilic polyoxyethylene sorbitan and hydrophobic fatty acid esters, made up the largest part being employed in 87% of said formulations.
Despite their frequent use in parenteral drug products, concerns have been raised for decades about the application of polysorbates as surfactants in biopharmaceutical formulations. Autoxidation of polysorbate, caused by residual peroxides in polysorbates, can damage the proteins and can further drive the oxidative degradation of polysorbate. Chemical and enzymatic hydrolysis of polysorbate may lead to the formation of free fatty acid particles, which may become visible; and both mechanisms eventually lead to the reduction in polysorbate concentration. Therefore, the purpose of the current study was to compare various molecules for their capabilities to reduced agitation-induced protein aggregation and particle formation; and furthermore, investigate their underlying protein stabilizing mechanisms.

Characterization of monoclonal antibodies and Antibody drug conjugates by Sur...Merck Life Sciences
Watch the presentation of this webinar: https://bit.ly/3Pjpjvr
Highlights of this webinar:
- Surface plasmon resonance as a powerful tool for biologic characterization including mAbs and ADCs.
- SPR allows rapid binding analysis in real time without using labels for SARS-CoV-2 receptor binding domain mutations.
- Kinetic data is indicative of possible neutralizing activity allowed assessment of neutralizing ability of therapeutic monoclonal antibodies.
- The application can provide preliminarily efficacy information and facilitated mAbs/ACDs candidate selection process
Detailed description:
Characterization of therapeutic monoclonal antibodies (mAbs) or Antibody drug conjugates (ADCs) is challenging due to their ability to bind to a variety of proteins via their Fc and Fab domains, giving rise to diverse biological functions associated with each domain. The Fc domain of mAbs interacts with Fc receptors with varying affinities, which can influence biological processes such as Complement-dependent cytotoxicity (CDC) and Antibody-dependent cellular cytotoxicity (ADCC), transcytosis, phagocytosis, and/or serum half-life.
An important characteristic of an antibody is its Fc effector function. Antibodies can be engineered to obtain desired binding of the Fc region to Fc receptors expressed on effector cells. Hence, it is crucial to evaluate the binding interaction of mAbs/ADC with Fc receptors in the early phase of drug development to understand the potential biological activity of the product in vivo.
Surface Plasmon Resonance (SPR) is a powerful technique to establish binding kinetics in real-time, label free, and high sensitivity with low sample consumption. Along with target antigen binding, it is crucial to evaluate the binding interaction of antibodies and ADCs with Fc receptors. Our SPR case studies investigated the impact on binding kinetics of ADCs with different linkers and the binding interactions of SARS-CoV-2 spike protein variants and evaluated the neutralizing ability of therapeutic mAbs. SPR characterisation can be facilitated in all stages of the product life cycle to ensure the quality and safety of mAbs and ADCs.

Improve Operational Efficiency by Over 30% with Product, Process, & Systems A...Merck Life Sciences
Watch the presentation of this webinar here: https://bit.ly/3adaxWh
When implementing new automation systems, organizations must consider things like deployment time, user adoption, and costs.
They must also consider the cost of doing nothing – that is, what competitive advantage is lost in standing still? What time and quality is lost in repetitive, manual tasks rather than an automated, digital workflow? What operational efficiencies are lost?
In this webinar we examine how a product, process, and system agnostic automation platform can be deployed faster than traditional system specific software while bringing greater operational efficiencies (in many cases over 30% improvement).
To remain competitive in the market, biopharma manufacturers must adopt automation and digital technologies, but most plants still have island of automation consisting of independently functioning, standalone unit operations. This results in operational inefficiency, regulatory concerns, and a poor understanding of the process and product life cycle.
Taking the first, right step must include considering risks, costs, timelines, and technology alternatives. Traditional automation approaches tied to specific systems, processes, and products are, by their nature, limited; while an agnostic platform will address current biomanufacturing business challenges and ensure future readiness. With the right platform, a phased automation implementation can yield operational efficiency gains of up to 30% and improved product quality and regulatory compliance.
In this webinar, let's explore:
• Challenges of automation and digital technology adoption
• What a product, process, and system agnostic platform entails
• Applications and benefits of a process orchestration platform
• Ensuring future readiness with process orchestration

Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

12. General strategy
Regulatory guidance on adventitious agent testing
12
• US FDA and WHO suggest full characterisation of
MCB and maximum PDL used for production cells
(EOPC); minimal testing on WCB.
• EP 5.2.3 01/2009 suggested that all adventitious
virus testing should be performed on EOPC but
new revision (01/2018) indicates that the
appropriate testing stages should be selected
based on a viral risk assessment and accepts
alternative strategies that focus on more
extensive testing at the MCB or WCB level.
• EP 5.1.7 Viral safety, describes parameters that
should be considered in a viral risk assessment.
13. Assays to detect adventitious viruses
•All documents aligned in recommending using live cells or cell lysate (at 107
cells/ml in
conditioned medium)
•In Vivo assay
• FDA guidance recommends adult mice (20 observed for 21 days); suckling mice (20,
observed for total 28 days with passage at 14 days); embryonated eggs (allantoic and
yolk sac inoculation with passage); Guinea pigs (42 days observation to detect
Mycobacterium)
• WHO recommends adult mice (20 observed for 28 days); suckling mice (20 , observed for
28 days but no passage at 14 days); Guinea pigs but can be replaced by in vitro method
for Mycobacterium; embryonated eggs but only if testing avian cell lines or novel cell
substrates.
• EP 5.2.3 only recommends inoculation of suckling mice (> 10, observed for 28 days) if
risk assessment indicates it provides risk mitigation taking into account the overall testing
package. Embryonated eggs only required for avian cell substrates.
Regulatory guidance on adventitious agent testing (2)
13
14. Retrovirus testing
•Similar approach recommended by FDA, WHO and EP
•If the cell line is not known to produce retroviral particles:
• Test using a product-enhanced reverse transcriptase (PERT) assay and examine by
transmission electron microscopy (TEM)
• If PERT and TEM give a positive or equivocal result test using an infectivity assay
•If the cell line is known to produce retroviral particles (e.g. rodent and avian cells)
• Test by TEM and using an infectivity assay
• If both TEM and infectivity are negative test using a PERT assay.
Regulatory guidance on adventitious agent testing (3)
14
15. Tests for specific viruses
•The list of specific viruses to be tested should be defined based on a viral contamination risk
assessment (defined in EP 5.1.7 Viral safety).
•Use PCR in cases where viruses cannot readily be grown in culture.
Specific human viruses
•FDA recommendations:
• Hepatitis A, B & C; HIV 1 & 2; HTLV 1 & 2; B19 parvovirus; EBV, CMV, HHV 6,7 & 8
• Enteroviruses, Circoviruses, papillomaviruses, human polyoma viruses, human adenovirus
• Should also consider simian viruses that could infect humans.
Specific bovine and porcine viruses
•FDA and WHO recommend testing for 9 bovine viruses and porcine parvovirus (trypsin)
specified in 9CFR 113.47 & 113.53
•Additional assays should be considered for:
• Bovine: bovine polyoma virus, bovine circovirus, bunyaviruses (Cache valley virus), EHDV
• Porcine: porcine circovirus, porcine hepatitis E virus, anelloviruses, hokovirus, bocavirus

massively parallel sequencing (MPS) methods,
degenerate PCR for whole virus families or random-
priming methods (associated or not with sequencing),
hybridisation to oligonucleotide arrays and mass
spectrometry. These methods may be used either as
an alternative to in vivo or specific NAT tests or as a
supplement/alternative to in vitro culture tests, in
agreement with the competent authority.’

“MP-Seq™”
Next Generation Sequencing
(High Throughput/Deep/Massively Parallel Sequencing)
High throughput, concurrent sequencing by synthesis with three basic steps:
20. • Extraction
Extract total nucleic acids — purify all genomes (RNA/DNA/ss/ds/ linear/circular)
Library must be dsDNA so convert all material using a cDNA synthesis kit (pre-processing)
• Library preparation
Shear DNA to an appropriate size range
Add adaptors to ends of fragments
Quantify DNA
Tagged DNA is then amplified to enrich for sequences containing the proper tags for sequencing
Amplification means the assay cannot be quantitative
There is no selection or targeting of virus sequences — all sequences are converted into the library
• Sequencing by synthesis
Addition of fluorescently-labeled nucleotides to complementary DNA strand releases fluorescent probe

24. MVSS should be screened fully for adventitious bacteria, fungi, mycoplasma,
mycobacterium and viruses taking account of the origin and isolation of virus stock
Neutralising antiserum is required for infectivity assays
Should be prepared from a stock that is different from stock used for production and prepared using
SPF animals
Not of human or simian origin
Pre-studies are required to ensure neutralisation of virus stocks before testing
Where neutralising antisera of high enough titre cannot be prepared a panel of PCR assays
may be used
Production control cells (not inoculated with virus) grown in same medium and handled
alongside production cells are tested for adventitious mycoplasma and viruses
EP 2.6.16 only recommends using suckling mice as the in vivo assay for adventitious
viruses.
‘Each virus seed lot is tested in suckling mice if the risk assessment indicates that this test provides a
risk mitigation taking into account the overall testing package.’

• Alignment of millions of reads
against one or more defined
reference sequences
• Unlike Sanger (consensus)
sequencing, NGS enables
sequencing & reporting of millions
to billions of individual molecules
→ analysis on a per molecule basis
• Exquisite variant detection down to
a single molecule level
• Sub-1% variant detection is possible
→ can identify ultra-rare variants

31. Develop a multi-faceted virus contaminant risk mitigation strategy when developing
a viral vaccine
Prevent: Ensure quality of raw materials
Detect: Implement testing package for cell banks,
maximum PDL cells, virus seed stocks and virus harvests
Inactivate/remove: Where possible implement virus
contaminant clearance technologies
Overall testing strategy for viral vaccines is shared by US FDA, WHO and EP
EP is recommending reducing in vivo virus detection assays and supplementing classical
virus detection and identity assays with new technologies such as NGS analysis
