Sector Call Summaries: Gene Therapy (2020)


>> View the call slide deck

1) SCB Updates

2) Landscape and Needed Standards Report feedback

Landscape Report feedback:

  • Add information on which standards are formally/informally FDA-recognized

  • Include more about framework of how SDOs are involved with SCB

  • Add more about implementation—how to do so, include links to relevant publications beyond the standards themselves

  • Add new sorting methods: types of products, processes, materials, equipment, quality/testing issues, supply chain

  • Capture search results for a pull-down menu of common terms

  • Include links to relevant documents, places standards can be purchased

  • Add list of standards related to starting materials for gene therapy products

Needed Standards Report feedback:

The gene therapy sector working group identified several ways to revise this report to make it more user-friendly and valuable, including adding standards needs related to:

  • Guidelines for vector quantification and validation

  • Reference standards for adeno-associated virus (AAV) antibodies

  • Validation of potency and purity assays

  • Comparability between assays for measuring immune response

3) SCB Project Updates

4) Communications Feedback

  • Invited feedback on ways to improve communication with stakeholders

5) Workshop/Courses

SCB is planning future workshop opportunities focused around standards for gene therapy. Possible topics include:

  • Measurement challenges and solutions for viral vector reference materials

  • Viral vector characterization, including needs, fit-for-purpose concerns, quality testing, and reporting

  • Data management needs

  • Impact of manufacturing standards on supply chain management

The new open ballots page was also shared.

1) COVID-19 UPDATES

  • Staff provided an update on plans to reschedule in-person SCB-hosted events from summer/fall to later in winter/spring

  • Shared updates from major standards developing organizations (SDOs), including virtual events and free access to standards relevant to COVID-19

2) SCB UPDATES

3) PROJECT UPDATES

4) IN-DEVELOPMENT STANDARDS

5) VIRAL VECTOR STANDARDS WORKSHOP

  • Staff shared plans for a September viral vector workshop hosted by the National Institute of Standards and Technology (NIST), Food and Drug Administration (FDA), and SCB. In advance of the workshop, SCB is collecting feedback for NIST and FDA on what viral vector standards are a priority for the field.

Participant feedback on high-priority viral vector standards for the field:

  • Reference materials and documentary standards related to titer in adeno-associated virus (AAV) vectors

  • Assay method for genomic titer (e.g., quantitative polymerase chain reaction [qPCR] and Digital Droplet PCR [ddPCR])

  • Standards addressing how viral vectors are classified and how quality is controlled in manufacturing processes where they are not the main component of therapy (e.g., CAR‑T therapy)

  • Definition of ancillary material versus raw material for viral vectors

  • A lexicon for newcomers to the field that captures definitions that are agreed on by experts but not written down

1) SCB News

  • Staff shared news about upcoming offerings, including standards implementation courses, planned feasibility reports, planned updates to the Regenerative Medicine Standards Landscape report, and a rapid microbial testing article that will be published in Cytotherapy journal.

2) Gene Therapy Standards Updates

3) Identification and Prioritization of Needed Standards

4) Upcoming Annual Meeting and SDO Forum

  • SCB is planning an annual meeting for January 2021 to inform the public about published and in-development standards, increase engagement with standards, and solicit input on standards needs.

  • There will be a meeting among SDO representatives in November to discuss current standards efforts under way and harmonize efforts, as well as focus on next steps for addressing community-identified needs.

1) SCB UPdates

Staff shared recent updates, including:

2) Cell Therapy Standards Updates

3) Identification and Prioritization of Needed Standards

  • Participants provided feedback on:

    • The functional areas with the greatest impact and urgency in the field

    • The standards areas with the greatest impact and urgency in the field

    • Which standards areas have the greatest community support

    • Which standards areas have the greatest scientific consensus

  • Participants also suggested additional standards needs to add to the report.

  • SCB will distribute a survey to gather additional feedback on these topics.

4) Upcoming Annual Meeting and SDO Forum

SCB is planning an annual meeting for January 2021 to:

  • Inform the public about published and in-development standards

  • Identify and prioritize needed standards

  • Increase engagement with standards

  • Answer questions on standards implementation
