European Society of Toxicologic Pathology (ESTP)
    European Society of Toxicologic Pathology
ESTP Committee for Regulatory & Scientific Standards

The CRSS is a dedicated committee under the auspices of the European Society of Toxicologic Pathology (ESTP). Team members are not chosen but volunteer to participate in the Committee and are all members of the ESTP. The number of members of the CRSS may vary but should be composed of at least 5 members. The respective ESTP STP SRPC liaison is automatically a member of the CRSS and should regularly participate in the meetings. The CRSS chair is responsible to ensure that regular meetings are held, communication to the ESTP board, recruitment of appropriate members to the CRSS, its continuation and the fulfilment of its tasks. The ESTP administrative support is responsible for the establishment of the meeting minutes and supports the CRSS in communication with other societies.

CRSS members commit to a regular participation in the meetings (generally 5-9 per year) of a minimum of 6 meetings annually to ensure a quorum for decision making and appropriate cover of all necessary activities.

Mission

The overall mission of the ESTP Regulatory and Scientific Standards Committee is

  1. to keep the ESTP membership updated on guideline documents and regulatory activities impacting the field of toxicologic pathology & drug/agrochemical development;
  2. to promote scientific excellence and appropriate visibility of ESTP member/working group contributions via reviewing/supporting publications for the Journal of Toxicologic Pathology in collaboration with the ESTP EC, and
  3. to appropriately influence regulatory guidance in the wider field of toxicologic pathology via commenting Draft guidelines in collaboration with the ESTP membership.

This includes (but is not necessarily limited to):

  • Review & Response to Draft regulatory guidelines (FDA, OECD, ICH, EMEA, EPA) impacting the work of toxicologic pathologists.
  • Information about Final Regulatory guidelines (or updates) to the ESTP membership (via e-mail and/or LinkedIn)
  • Review of Publications provided by STP/BSTP/ESTP for publication in Toxicologic Pathology in the scope of the respective MoU and ESTP Procedures.
  • Support ESTP working groups/authors in providing guidance on the Categories of Publication and review of the respective Charters.
  • May initiate new proposals for Working Groups to prepare Best Practice Papers, Points to Consider Papers or Opinion Papers which are interesting for the toxicologic pathology community.
  • Link to STP SRPC (Scientific Regulatory Policy Committee) via the ESTP STP SRPC liaison.
  • Link to ESTP Associate Editor regarding ESTP banner publications in the Journal of Toxicologic Pathology
  • Create efficient and robust process documents and participate in review and finalization of process documents and Society MoUs which impact the above-mentioned activities of the CRSS.

Procedure:

  • Internal communication within the CRSS is guaranteed by regular on-line meetings in which all main activities of the committee mentioned above are discussed. Communication also occurs via e-mail when more information, detail or contribution for specific subjects or issues is needed.
  • Meetings minutes are prepared and made available in the member area of the ESTP website.
  • External communication is mainly done by e-mail, in most cases via the ESTP administrator.
  • Individual members of the CRSS are responsible to regularly review websites of specific regulatory bodies (i.e. EMA, FDA, ICH, OECD, EPA, EFSA/ECA) to inform the Committee of any new draft guidelines or updates which fall within the scope of the CRSS.
  • The ESTP STP SRPC liaison will share STP SRPC activities at the CRSS meetings and regularly share STP SRPC minutes with the CRSS and the ESTP EC.
  • The CRSS reviews Draft publications to be published under the ESTP banner in Toxicologic Pathology and equally Draft publications to be reviewed from other societies seeking ESTP endorsement/approval/ratification, as well as in the scope of the societies MoUs following the respective procedures.
  • Review & Response to Draft Guidelines
    • For Guidelines impacting directly the work of Toxicologic Pathologists, depending on the Review period for comments, the CRSS first reaches out to the ESTP membership to collect comments, and then prepares a collation of comments with a general assessment (if applicable) to be shared with the ESTP EC for comment and endorsement within a given timeframe; the ESTP EC will respond within the timeframe following the respective procedure (generally within 10 WDs).
    • The CRSS chair (or delegate) is responsible to organize a timely submission of the comments document in collaboration with the ESTP EC and administrator (official signatures)
  • Information about Final or updated Regulatory Guidelines:
    • Final/Updated Regulatory Guidelines: An informative email with bullet points highlighting the relevant information is prepared by a member and is after approval by other members (at least one) distributed to the ESTP-members via the ESTP administrator for information. Depending on the impact for the field of Toxicologic Pathology, the information is shared with the Councillor for the Website to be posted in the Members Only area.
  • Review of Draft Projects/Publications under ESTP banner for Publication in the Journal of Toxicologic Pathology
    • Working group projects: when solicited, the CRSS provides the Draft Charter form to gather the relevant overview to be able to provide guidance on the potential category of the final publication.
    • Draft Publication for final endorsement: the CRSS reviews the publication and provides the document (incl. comments; if applicable) with a recommendation to the ESTP EC for approval following the respective procedure and timelines.
  • Review of Draft Projects/Publications from STP/BSTP or other societies for Publication in the Journal of Toxicologic Pathology
    • the CRSS reviews the publication and provides the document (incl. comments; if applicable) with a recommendation to the ESTP EC for approval following the respective procedure and timelines.
  • General support
    • Active involvement in preparing or updating SOPs or Society MoUs (e.g. on the different publication categories).
    • Propose new subjects for Working Groups that can prepare publications on interesting issues for the Toxicologic Pathology Community.

Mission: Scientific standards for scientific value

The ESTP Committee for Regulatory & Scientific Standards (CRSS) has reviewed the following guidance documents or position papers:

  • FDA draft guidance on "Nonclinical safety evaluation of the immunotoxic potential of drugs and biologics" (February 2020) : a comparison with the withdrawn FDA guidance on Immunotoxicology evaluation of investigational new drugs (2002) was made and a tabulated summary of changes in the new guidance summary is presented here:

    FDA Guidance - Version 2002b FDA Guidance - Draft Version 2020a
    Guidance applicable to small molecules only Guidance applicable to small molecules + some biologics (therapeutic proteins and recombinant/plasma-derived blood proteins)
    Focuses mainly on immunosupression Focuses also on immunostimulation (ex: TGN1412) with in vitro assays assessing immune activation, cytokine release and ligand-receptor interactions
    No corresponding ICH guidelines except ICH S6 (1st version) Refers to ICH S8c (2006), S11d (2020), S9e (2010), S5 R3f (2020) in addition to S6 R1g (2012)
    Developmental immunotoxicity limited to standard DART studies Juvenile Tox studies (all species) + NHP enhanced PPND study added in addition to standard DART studies
    For TDAR : SRBC Plaque Assay was recommended as 1st choice KLH is now the 1st choice for TDAR assay
    T-DAR is also proposed for increased IgM/G production in addition de decreased IgM/G production.
    Dogs and monkeys were the only two NR species recommended Minipig added in non rodent species in addition to dogs and NHPs
    LLNA recommended LLNA not recommended anymore (limits for this test) – In vitro tests recommended instead (OECD guidelines 2019 test No. 442C/D/E)
    a FDA draft guidance for Nonclinical safety evaluation of the immunotoxic potential of drugs and biologics (February 2020) https://www.fda.gov/media/135312/download
    b FDA guidance for Industry Immunotoxicology Evaluation of Investigational New Drugs (October 2002) https://www.fda.gov/media/72228/download
    c ICH S8 Immunotoxicity studies for human pharmaceuticals (April 2006)
    d ICH S11 Nonclinical Safety Testing in Support of Development of Paediatric Medicines (January 2019)
    e ICH S9 Nonclinical Evaluation for Anticancer Pharmaceuticals – Questions and Answers (June 2018)
    f ICH S5(R3) Detection of Toxicity to Reproduction for Human Pharmaceuticals (November 2017)
    g ICH S6(R1) Preclinical Safety Evaluation of Biotechnology-Derived Pharmaceuticals (May 2012)

  • FDA guidance for industry, clinical laboratories, healthcare facilities, pathologists and FDA staff on "Enforcement Policy for Remote Digital Pathology Devices During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency" (April 2020): this policy, which is effective during the public health emergency related to Covid-19 only, is provided by the FDA to expand the availability of devices for remote evaluation of digital pathology images. Although applying only to medical pathologists from clinical laboratories and hospitals, it is also a positive signal for the current shift toward a digital pathology approach in the preclinical safety and toxicologic pathology and its acceptance by the regulatory authorities.
  • EMEA-related guidelines: there are 2 Final Guidelines that will be effective in July 2020
    • Guideline on assessment and control of DNA reactive (mutagenic) impurities in veterinary medicinal products (1 July 2020)
    • ICH S5 (R3) guideline on reproductive toxicology: Detection of toxicity to reproduction for human pharmaceuticals- step 5 (30 July 2020)
  • EMEA: There is a lot of information concerning Covid-19 on the website of EMEA that may be of interest for the toxicologic pathologist (e.g the treatments and vaccines now under investigation and guidance for developers and companies)
  • OECD GLP Position paper regarding possible influence of sponsors on conclusions of GLP Studies (7th May 2020)

The Scope of the ESTP Committee for Regulatory & Scientific Standards (CRSS, formerly the Guideline Committee) has a dual focus:

The internal focus is to update and inform the ESTP members about recent developments, changes and issues affecting guidelines and scientific standards which impact the daily work of toxicopathologists and correlated scientific fields. This should happen in an interactive fashion. Comments, proposals and criticism are welcome via email or in the Members Only area. The opinions and feed-back of the members will be a useful tool for the second focus:

The external focus of the CRSS is the generation of comments or position papers related to guidelines and scientific standards which are then released by the ESTP Board and sent towards the regulatory bodies as input to these draft guidelines. The CRSS may also review draft Points to Consider documents (eg from other Societies) which could have an impact on our work and thus ensure partnership with international STP Regulatory & Guideline committes. The process we follow is as follows:

  • Individual members of the CRSS are responsible for reviewing websites of specific regulatory bodies (namely EMA, FDA, ICH, OECD, EPA) and informing the Committee of any draft guidelines which fall within the scope of the CRSS.
  • The CRSS will develop preliminary comments on behalf of the ESTP which are then submitted to the Society's Executive Board for endorsement; the Board will make efforts to respond within 10 days. The CRSS comments will be made available in parallel in the Members Only area and any member of ESTP is invited to make further comments or suggestions.
  • If the Executive Board feel that the draft guideline could have a particularly significant impact on our work then a more proactive engagement of the Society's membership may be proposed (including an extension of time available, if possible).
  • The ESTP website will be updated with the final set of comments submitted to the regulatory body in question.
  • Once the final guideline is published a statement to that effect (and a link) will be placed on the ESTP website.

The information available is placed under the categories shown below. Please note that most of the documents are available as PDF files.
