Additional measures to allow experts to focus on COVID-19 activities
The new temporary measures include: -
For Pre-authorisation procedures: -
All initial marketing authorisation applications (MAAs) for COVID-19 vaccines and therapeutics will continue to be given first priority. There will continue to be two independent, simultaneous scientific assessments with separate initial reports for these procedures, with no change to the current responsibilities of the rapporteur and co-rapporteur at EMA’s human medicines committee (CHMP).
For initial MAAs for non-COVID-19 products, unless they are advanced therapy medicinal products (ATMPs) or other very complex medicines to be considered by the CHMP, the co-rapporteur will no longer provide a separate assessment report to the rapporteur in the first phase of the evaluation. Instead, he or she will review the submitted data and give a detailed critique of the rapporteur’s assessment report. These measures will free up some of the co-rapporteur resources to focus on COVID-19 activities.
For all applications, there will temporarily no longer be a separate, formally appointed peer reviewer, but the assessment will rely on the intrinsic peer review that is part of the CHMP’s role in the evaluation process. In the case of COVID-19 products, there are additional reviews by the COVID-19 EMA pandemic Task Force (COVID ETF).
These measures will apply to initial MAAs starting in May 2021.
For Post-authorisation procedures: -
Currently, the involvement of co-rapporteurs in the assessment of post-authorisation procedures to extend indications and extension applications (so-called line extensions) depends on the complexity of the file. The approach to these procedures is being temporarily amended as follows:
For COVID-19 products, the co-rapporteur will be systematically involved in all such procedures; however, the need for two separate assessment reports, or for providing a detailed critique of the rapporteur’s assessment report, will depend on the complexity of the application.
For non-COVID 19 products, when the co-rapporteur is involved, the co-rapporteur will produce comments on the rapporteur’s assessment report but will not draft a full separate report in the first phase of the evaluation.
These changes will take effect from May 2021.
Frequently asked questions
EMA has recently updated its FAQ pages
EMA / ANVISA Confidentiality Agreement
The European Commission, EMA and Brazil’s Agência Nacional de Vigilância Sanitária (ANVISA) signed a confidentiality arrangement in 2021. It is valid for an indefinite period of time, unless terminated by either party.
Minutes of the 111th meeting of the EMA Management Board
EMA has published the minutes of this meeting which took place virtually on 11 March 2021.
New Organization First User QPPV/RP or Change of EU QPPV/RP
If a change of qualified person for pharmacovigilance/responsible person for EudraVigilance (QPPV/RP), named person or legal representative within the organisation occurs, you need to notify EMA. There are 2 possible scenarios,
A) There is still a QPPV/RP in your organisation–change of QPPV/RP
B) There is no QPPV/RP in your organisation–first user QPPV/RP of a new organisation
Procedural advice for medicinal products intended exclusively for markets outside the European Union in the context of co-operation with the World Health Organisation (WHO)
EMA has updated this advice. This document addresses a number of questions that users of Article 58 of Regulation (EC) No 726/2004 may have. It provides an overview of the EMA’s position on issues that are typically addressed in pre-submission meetings. The EMA emphasises the importance of pre-submission meetings with applicants. These meetings are an opportunity for applicants to obtain procedural and regulatory advice to streamline the submission of their application. Together with the guidance in this document, successful pre-submission meetings should enable applicants to submit applications that conform to legal and regulatory requirements and that can be validated speedily. Pre-submission meetings also enable applicants to establish contact with the EMA product team who will be involved with the application as it proceeds. In addition, applicants are actively encouraged to seek scientific advice as early as possible in the development process.
Addendum to the guideline on testing for carcinogenicity of pharmaceuticals S1B(R1)
EMA has published this endorsed draft version ICH guideline.
This Addendum covers all small molecule pharmaceuticals where carcinogenicity evaluations are recommended as described in S1A. This Addendum expands theesting scheme for assessing human carcinogenic risk of small molecule pharmaceuticals by introducing an additional approach that is not described in the original S1B Guideline is an integrative approach that provides specific weight of evidence (WoE) criteria that inform whether or not a 2-year rat study adds value in completing a human carcinogenicity risk assessment. The Addendum also adds a plasma exposure ratio-based approach for setting the high dose in the rasH2-Tg mouse model, while all other aspects of the recommendations for high dose selection in S1C(R2) Guideline would still apply.
ICH Q3C (R6) Residual solvents
EMA has updated its advice on this topic.
Medical Device Regulation comes into application
The Medical Device Regulation (MDR), which was adopted in April 2017, changes the European legal framework for medical devices and introduces new principal and supportive responsibilities for EMA and for national competent authorities in the assessment of certain categories of products. The Regulation entered into force in May 2017 and had a staggered transitional period.
The MDR introduces new or revised responsibilities for EMA for:
medicines with an integral device, such as pre-filled syringes and pens, and pre-filled inhalers;
medical devices containing an ancillary medicinal substance to support the proper functioning of the device. Examples include drug-eluting stents, bone cement containing an antibiotic, catheters coated with heparin or an antibiotic agent and condoms coated with spermicides;
medical devices made from substances that are absorbed by the human body to achieve their intended purpose;
borderline products for which there is uncertainty over which regulatory framework applies. Common borderlines are between medicinal products, medical devices, cosmetics, biocidal products, herbal medicines and food supplements.
To support the implementation of the MDR, updated guidance on quality requirements for medical devices in human medicines that include a medical device, as well as an updated Q&A, are currently under preparation and will be published shortly.
EDQM
Particulate contamination: sub-visible particles – PDG revision of general chapter released for public consultation
A new, revised version of general chapter 2.9.19. Particulate contamination: sub-visible particles has been published in Pharmeuropa 33.2. In addition to applying to solutions for dialysis, the European Pharmacopoeia requires this test to be performed for liquid parenteral preparations (0520), sterilised water for injections (0169) and solutions for organ preservation (1264).
This new version is the result of lengthy and fruitful discussions with experts from the Japanese Pharmacopoeia and the United States Pharmacopoeia within the Pharmacopoeial Discussion Group (PDG). The three pharmacopoeias each made a significant effort to come to a consensus on an updated text that is now undergoing public consultation in all three regions.
Comments to be submitted before 30 June 2021.
Adoption of the revised General Notices chapter
The European Pharmacopoeia (Ph. Eur.) Commission adopted a revised version of chapter 1. General Notices.
The chapter was overhauled to provide greater clarity for users, the structure and content of the chapter have also been reviewed.
The chapter features new additions such as a section on monographs for medicinal products containing chemically defined active substances. This new section also provides information on related substances and impurities taken from the relevant Technical Guide.
The wording and terminology have been further harmonised and clarified. E.g, synonyms have been weeded out, with “medicinal product” selected over the formerly interchangeable “finished product” and “pharmaceutical preparation”.
Further terminological changes include “shelf life” and “re-test period” instead of “period of validity” and “period of use”, in accordance with the ICH guidelines. Definitions have also been added for “freshly prepared solution” and “immediately before use”.
Another addition is a sub-section on “Demonstration of suitability of monographs” that provides useful guidance for users.
The scope of first and second identification series and of alternative identifications described in monographs have been clarified and several changes, including an explanation of the rounding rule, information on chiral substances and an example of equivalents, have been introduced in the tests and assay sections of the General Notices.
Lastly, all the paragraphs concerning monographs on herbal drugs that were previously dispersed throughout the text are now gathered together in a single section, for enhanced readability.
The revised chapter will be published in Ph. Eur. Supplement 10.7, available in October 2021.
United States of America
The US Food and Drug Administration (USFDA)
The US FDA has recently published six ICH documents. Three of these are of particular interest / relevance to readers of The Update and are referenced below.
S5(R3) Detection of reproductive and developmental toxicity for human pharmaceuticals
This guidance revises the ICH guidanceS5 Detection of Toxicity to Reproduction for Medicinal Products (September 1994). This revision brings the guidance into alignment with other ICH guidances, elaborates on the use of exposure margins in dose-level selection, incorporates a section on risk assessment, and expands the scope to include vaccines and biopharmaceuticals. It also describes qualification of alternative assays, describes potential scenarios of use, and provides options for deferral of developmental toxicity studies. To assess a human pharmaceutical’s effect on reproduction and development, there should generally be information available that addresses the potential impact of exposure to a pharmaceutical and, when appropriate, its metabolites (ICH M3 (ref. 1), ICH S6 (ref. 2)) on all stages of reproduction and development. No guidance can provide sufficient information to cover all possible cases, and flexibility in testing strategy is warranted.
Q12 Technical and Regulatory Considerations for Pharmaceutical Product Lifecycle Management
This guidance provides a framework to facilitate the management of post approval chemistry, manufacturing, and controls (CMC) changes in a more predictable and efficient manner. A harmonized approach regarding technical and regulatory considerations for lifecycle management will benefit patients, industry, and regulatory authorities by promoting innovation and continual improvement in the pharmaceutical sector, strengthening quality assurance, and improving supply of medicinal products. The concepts outlined in prior ICH Quality guidances for industry (ICH Q8(R2), Q9, Q10, and Q11) provide opportunities for science- and risk-based approaches for use in drug development and regulatory decisions. These guidances are valuable in the assessment of CMC changes across the product lifecycle. ICH Q8(R2) and Q11 guidances focus mostly on early stage aspects of the product lifecycle (i.e., product development, registration, and launch). This guidance addresses the commercial phase of the product lifecycle (as described in ICH Q10) and it both complements and adds to the flexible regulatory approaches to post approval CMC changes described in ICH Q8(R2) and Q10 Annex 1.This guidance is also intended to demonstrate how increased product and process knowledge can contribute to a more precise and accurate understanding of which post approval changes should result in a regulatory submission as well as the definition of the levels of reporting categories for such changes (i.e., a better understanding of risk to product quality). Increased knowledge and effective implementation of the tools and enablers described in this guidance should enhance industry’s ability to manage many CMC changes effectively under the company’s Pharmaceutical Quality System (PQS) with less need for extensive regulatory oversight prior to implementation. This approach can incentivize continual improvement by providing an opportunity for greater flexibility in making post approval changes. It could also result in fewer associated post approval submissions to the Marketing Authorization Application (MAA) and less associated regulatory burden. The extent of this operational and regulatory flexibility and its adequate implementation is subject to the regulatory framework in place, as well as product and process understanding (ICH Q8(R2) and Q11), application of quality risk management principles (ICH Q9), and an effective PQS (ICH Q10).
Also published is an Annex to Q12. The examples provided in sections I.A through I.F of the ICH Q12 Annexes are mock examples provided for illustrative purposes. They only suggest how the tools described in sections III, IV, and V of the ICH Q12 guidance could be applied, and should not be used as a template or the sole basis for a regulatory submission. In addition, the reporting categories, as described in section II of the ICH Q12 guidance, may differ across regions depending on regional legislation; the nature of the product; and the Marketing Authorization Holder’s (MAH’s) demonstrated understanding of the product, process, and analytical procedure.
ICH Q12: Implementation considerations for FDA-regulated products
This draft guidance should be read in conjunction with ICH Q12, which this guidance complements by clarifying how the ICH Q12 tools and enablers can be implemented within the U.S . regulatory system. These guidances apply to drug substances and drug products that are the subject of new drug applications (NDAs), biologics license applications (BLAs), abbreviated new drug applications (ANDAs), and supplements to these applications regulated by the Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER). They also apply to combination products with device constituent parts that are the subject of NDAs, BLAs, ANDAs, and supplements to these applications regulated by CDER and CBER.
Q3D(R2) Elemental Impurities
This draft document for public consultation is comprised of extracts of the Q3D(R2) Guideline with the revisions to the Q3D(R1) Guideline:
Part 1 - Extract of Appendix 2: Correction of PDEs for Gold, Silver and Nickel
Part 2 - Extract of Appendix 3: Correction of Gold monograph
Part 3 - Extract of Appendix 3: Correction of Silver monograph
Part 4 - New Appendix 5
development of bispecific antibodies, which are genetically-engineered, recombinant antibodies that consist of two distinct binding domains capable of binding two different antigens or two different epitopes of the same antigen A scientific rationale often exists for engaging two targets in the therapeutic strategy for a specific disease. Bispecific antibodies can target multiple disease-modifying molecules with one drug, with possible advantages over combination therapy or the use of antibody mixtures. The possibility of immune cell retargeting through the delivery of an effector or effector cell to a specific target cell or the possibility of synergistic efficacy through engagement of multiple targets gives bispecific antibodies the potential to advance the development of antibody-based therapies. Challenges may arise in developing bispecific antibodies such as immunogenicity related to novel structures and complex structural and functional characterization.
This final guidance provides recommendations to assist industry and other stakeholders involved in the development of bispecific antibodies. In addition to general considerations, the guidance provides recommendations for specific regulatory, quality, nonclinical, and clinical considerations for bispecific antibody development programs. Although this guidance is intended for bispecific antibodies, the principles discussed in this guidance may also inform the development of other types of bispecific protein products and multi-specific products.
International
Australia
Australia Therapeutic Goods Administration (TGA)
Guidance on the management of GMP compliance signals
The guidance outlines the GMP compliance requirements for manufacturing biologicals and medicines intended for supply in Australia and our framework for managing GMP compliance signals.
This guidance applies to:
licensed manufacturers in Australia
sponsors responsible for any overseas site in the manufacture of a Medicine or active pharmaceutical ingredient supplied to Australia.
Faecal microbiota transplant (FMT) products regulation
On 1 January 2020, TGA provided clarity for the new regulatory model for FMT products. Following an 18-month transition period, the new regulatory requirements for FMT products commenced on 1 July 2021.
Most FMT products are regulated as biologicals. This includes significantly processed products (e.g. capsules) that are derived from stool. How an FMT product will be regulated by TGA depends on the level of clinical oversight and external governance in its preparation.
As a general principle, most FMT products will currently be regulated as either Class1 or Class 2 biologicals depending on whether or not they are:
manufactured in a hospital
minimally manipulated
However, where a strain(s) of microorganisms, known to be present in stool, is characterised and grown from established isolates with standardised consistency, it may be regulated as a medicine rather than a biological.
From 1 July 2021, the supply of FMT products can only occur in Australia where:
TGA has included the product in the Australian register of therapeutic goods (ARTG) or
TGA has granted approval or been notified utilising the ‘unapproved’ product pathways where specific criteria are met
Consultation: Remaking of standards and legislative instruments for human cell and tissue (HCT) products, blood and blood components
is conducting a public consultation seeking feedback on a proposal to remake some of the legislative instruments relating to human cell and tissue (HCT) products (including blood and blood components), which sunset in October 2021.
The TGOs relevant to this consultation can be broadly categorised into three groups:
Product-specific standards: TGO 83,84,85 & 86.
Labelling requirements: TGO 87
General donor selection and testing requirements: TGO 88
This consultation will also consider two other legislative instruments: Therapeutic goods -Things that are not biologicals and Therapeutic goods -Things that are biologicals
The consultation opens on 27 May 2021. Interested parties should respond by close of business 11 July 2021
PIC/S
Revision of PIC/S Blood Guidance Documents (PE 005-4 and PI 008-4)
The following two PIC/S guidance documents have been revised:
PE 005-4: PIC/S Good Practice Guidelines for Blood Establishments and Hospital Blood Banks
PI 008-4: PIC/S Aide Memoire to Inspections of Blood Establishments and Plasma Warehouses
The revised guidance documents enter into force on 1 June 2021.

More flexible storage conditions for BioNTech/Pfizer’s COVID-19 vaccine
EMA’s human medicines committee (CHMP) has recommended a change to the approved storage conditions of Comirnaty , the COVID-19 vaccine developed by BioNTech and Pfizer, that will facilitate the handling of the vaccine in vaccination centres across the European Union (EU).
This change extends the approved storage period of the unopened thawed vial at 2-8°C (i.e. in a normal fridge after taking out of deep-freeze conditions) from five days to one month (31 days). The change was approved following assessment of additional stability study data submitted to EMA by the MA holder. Increased flexibility in the storage and handling of the vaccine is expected to have a significant impact on planning and logistics of vaccine roll-out in EU Member States. Australia’s TGA has made a similar decision
First COVID-19 vaccine approved for children aged 12 to 15 in EU
EMA’s CHMP has recommended granting an extension of indication for the COVID-19 vaccine Comirnaty to include use in children aged 12 to 15.
One-dose Janssen COVID-19 vaccine approved by the UK MHRA
The COVID-19 Vaccine Janssen has been given regulatory approval by the MHRA.
This is the fourth COVID-19 vaccine to be authorised by the UK’s regulator and is the first to be approved for protection against COVID-19 with a single dose.
Safety updates COVID-19 vaccines
EMA has published several safety updates for EU approved COVID-19 vaccines
EMA starts rolling review of COVID-19 Vaccine (Vero Cell) Inactivated
EMA’s CHMP has started a rolling review of COVID-19 Vaccine (Vero Cell) Inactivated, developed by Sinovac Life Sciences Co., Ltd. The EU applicant for this medicine is Life'On S.r.l.
The CHMP’s decision to start the rolling review is based on preliminary results from laboratory studies (non-clinical data) and clinical studies. These studies suggest that the vaccine triggers the production of antibodies that target SARS-CoV-2, the virus that causes COVID-19, and may help protect against the disease.
EMA will evaluate data as they become available to decide if the benefits outweigh the risks. The rolling review will continue until enough evidence is available for a formal marketing authorisation application.
EMA issues advice on use of sotrovimab (VIR-7831) for treating COVID-19
EMA’s human medicines committee (CHMP) has completed its review on the use of the monoclonal antibody sotrovimab (also known as VIR-7831 and GSK4182136) to treat patients with COVID-19. This review was undertaken to provide a harmonised scientific opinion at EU level to support national decision-making on the possible use of the antibody prior to marketing authorisation.
The Agency concluded that sotrovimab can be used to treat confirmed COVID-19 in adults and adolescents (aged 12 years and above and weighing at least 40 kg) who do not require supplemental oxygen therapy and who are at risk of progressing to severe COVID-19.
The medicine is given by infusion (drip) into a vein.
EMA reply to ‘Doctors for COVID ethics’ letters
EMA acknowledges receipt of follow-up letters dated 1 and 20 April 2021 regarding the COVID-19 vaccines. It strongly rejects any accusations of complacency and concealing the truth.
In fact, EMA is providing enhanced transparency of its regulatory activities on treatments and vaccines for COVID-19, beyond that provided for other medicines. In this respect EMA is publishing clinical data submitted as part of regulatory procedures on COVID-19 medicines.
In addition to being more transparent, EMA also routinely communicates to the public and to healthcare professionals on all outcomes of its assessments through dedicated press releases and direct healthcare professional communication,
EMA is therefore providing comprehensive and invaluable information to support informed treatment decisions. EMA is fully committed to following scientific evidence in all its decisions. It is mobilising extensive resources to closely monitor safety and assess any new information for all COVID-19 vaccines as outlined in their respective pharmacovigilance plans.
The European Commission granted marketing authorisations to the COVID-19 vaccines based on favourable CHMP scientific opinions. These opinions confirmed that the COVID-19 vaccines are compliant with the technical requirements in Directive 2001/83/EC, applicable to all medicines, and the provisions in Regulation (EC) No 726/2004 which allow for a conditional marketing authorisation to be granted on less comprehensive data than normally required.

Call for Advanced Therapies to be exempt from EU GMO legislation (Joint industry association paper [ARM/EFPIA/EuropaBio])
The European Commission should exempt advanced therapies from Genetically Modified Organism (GMO) legislation, which hurts Europe’s ability to attract clinical trials and delays patient access to transformative medicines, said the Alliance for Regenerative Medicine (ARM), the European Federation of Pharmaceutical Industries and Associations (EFPIA), and the European Association of Bioindustries (EuropaBio) in a paper published online yesterday in the journal Human Gene Therapy. The European Commission recognized that GMO requirements hinder the conduct of clinical trials in its April 29 study on new genomic techniques and in the 2020 Pharmaceutical Strategy for Europe, when it called for GMO legislation to be “fit for purpose” for addressing medicines. The original GMO legislation was primarily enacted to protect food consumers and the environment, but Advanced Therapy Medicinal Products (ATMPs) such as gene therapies are affected as an unintended consequence. The uneven application of GMO requirements across EU Member States causes significant clinical trial delays despite findings that gene therapies pose a negligible risk to the environment. Galvanized by the pandemic, the European Commission granted a temporary derogation from GMO requirements to investigational COVID-19 medicinal products to accelerate the development of vaccines and treatments. An industry survey suggested that the temporary derogation decreased the amount of time required to complete clinical trials in Europe. A similar, but permanent, exemption is justified for gene therapies which often treat life-threatening diseases that have few, or no, treatment options – while still preserving high quality and safety standards.
ARM, EFPIA, and EuropaBio look forward to engaging with the European Commission and other stakeholders to find the best possible solutions to ensure that Europe is a competitive destination for the development of advanced therapies and that European patients have access to the most innovative, life-changing treatments.
Call for postponed application and phased implementation of the in vitro diagnostic Regulation (joint (EFPIA)(ECPC) concerns)
EFPIA, the European Cancer Patient Coalition (ECPC) and Diaceutics have shared their concerns related to the lack of readiness of the healthcare sector ahead of the date of application of the in vitro diagnostic Regulation (IVDR) with European institutions calling for its phased implementation. While they agree that well-regulated diagnostics are critical for quality testing, they are concerned that the infrastructure supporting the transition to this new regulation will not be ready in time to ensure the continued availability of tests required for cancer patients whose therapeutic management relies on the delivery of appropriate in vitro diagnostics.
With exactly one year to go before the date of application of the IVDR, only four Notified Bodies (NBs) have been designated to date (22 under the previous legislation) whereas the workload to assess diagnostics for NBs is estimated to increase by 600-700% under the new regulation compared to the situation under the existing legislation. Additionally, current device certification capacity is so limited that product files are taking on average 9 to 12 months for review regardless of the device classification.
Should institutions not agree to a phased implementation, we believe that most diagnostics currently on the EU market will not be authorised for use in EU Member States healthcare systems as of 26 May 2022, severely impacting the management of cancer patients across Europe.
And finally…
