Scientific and Regulatory Considerations for Assessment of Immunogenicity Risk for Generic Peptide and Oligonucleotide Drug Products

Date and Time: October 7 , 8:30 am  –  5:35 pm ,
October 8 , 8:30 am  –  5:10 pm

Co-hosts: FDA and the Center for Research on Complex Generics (CRCG)

In person (at The Universities at Shady Grove; Rockville, MD) and virtual workshop.

Workshop Registration

The purpose of this workshop is to engage stakeholders industry, academia, and FDA in a discussion on the scientific and regulatory challenges associated with immunogenicity risk assessment for proposed generic peptide and oligonucleotide drug products.

Experts from the FDA, new and generic drug developers, academic institutions, contract research organizations (CROs), consultants and other scientists involved in generic peptide and oligonucleotide drug product development will collaborate to improve our understanding of the role of immunogenicity risk assessment in supporting generic peptide and oligonucleotide drug product development and enhancing the consistency of risk assessment. The workshop will also allow all interested parties to participate in in depth discussions via working sessions to analyze examples.

The talks and discussions on Day 1 will center on best practices used to assess the immunogenicity risk ascribed to both product- and process-related impurities that may be present in synthetic generic peptide products. The use of in silico and in vitro assays to assess major histocompatibility complex (MHC) binding and T cell responses will be discussed. In addition, several talks and discussions will center on the assessment of innate immune response modulating impurities in generic peptide products. On Day 2, the topics will shift to focus on the information that these methods can yield to inform the immunogenicity risk assessment of recombinant peptide and generic oligonucleotide products.

Through coordinated talks from regulatory, academic and industrial experts, attendees will gain an understanding of useful strategies, potential pitfalls (such as cell viability), considerations for reference standard selection, and statistical approaches to assess differences between datasets, as well as gaining clarity about regulatory expectations.

Virtual Attendees will have free access to all sessions of the workshop except the small group (in-person) working sessions. Virtual attendees will be able to:

  • Attend all presentations and panel discussions
  • Participate in all Q&A panel discussions by submitting questions online in real time to the speakers and panelists
  • Enjoy free access to workshop recordings of presentations and panel discussion (not including the working sessions)

In-Person Attendees will enjoy all the benefits of virtual attendees, and will also play an active part in improving how immunogenicity risk assessment can support generic peptide and oligonucleotide drug products development by:

  • Collaborating in person with FDA, industry, and academic experts throughout the workshop, and particularly during small group working sessions
  • Engaging in dialogue with attendees and faculty about the challenges associated with conducting both adaptive and innate immunogenicity assays and the basis for regulatory expectations when conducting such assays
  • Conversing with panelists during discussion panel Q&As
  • Networking with colleagues during breaks

Workshop Topics

  • Adaptive immunogenicity risk assessment for generic peptide drug products using in silico and in vitro approaches
  • Innate immunogenicity risk assessment for generic peptide drug products using in vitro innate immune response modulating impurity (IIRMI) assays
  • Immunogenicity risk assessment of host cell protein contaminants in peptide drug products
  • Alternative models for immunogenicity risk assessment of peptide drug products

Audience

This workshop is primarily developed for generic drug industry, academic institutions, CROs, consultants, and others interested in the development of generic peptide and oligonucleotide drug products.

  • Virtual Attendance is optimal for an audience that is interested in an introduction to the assessment of immunogenicity risk for generic peptide and oligonucleotide drug products.
  • In-Person Attendance is optimal for an audience that is invested in actively engaging with the FDA, industry colleagues, representatives from CROs, and consultants to discuss and develop best practices to address the scientific and regulatory challenges associated with immunogenicity risk assessment for proposed generic peptide and oligonucleotide drug products.

Introduction to the Workshop

This two-day hybrid (virtual and in-person) workshop is focused on addressing current challenges associated with immunogenicity risk assessment for complex generic peptide and oligonucleotide drug products.

Day 1:

Session 1: Adaptive Immunogenicity Risk Mitigation – Product-Related Impurities

Format: Presentations and a Panel Discussion Q&A (Virtual and In-Person Attendees)

  • In this session, regulators and industry presenters will provide an introduction to the major histocompatibility complex (MHC). The in silico analysis and in vitro MHC binding tools available will be discussed. Strategies for standardization of in vitro assay protocols will be considered including selection of cell lines, reference standard sourcing and qualification, and establishing appropriate test compound assay concentration.

Session 2: Innate Immunogenicity Risk Mitigation –Process-Related Impurities

Format: Presentations and a Panel Discussion Q&A (Virtual and In-Person Attendees)

  • This session will discuss the innate immune response modulating impurity (IIRMI) assay in the context of protocols, appropriate controls and reference standards, selection of cell lines, and assay validation.

Session 3: In-Person Activities (Working Session)

Format: Small Group Working Sessions (In-Person Attendees Only)

  • Small group working sessions will involve structured activities with in-person attendees, focusing on the areas discussed during Day 1 of the workshop. Discussions will consider the challenges with conducting both adaptive and innate immunogenicity assays and understanding the regulatory expectations for conducting such assays.

Day 2:

Session 4: Host Cell Proteins and Alternative Models

Format: Presentations and a Panel Discussion Q&A (Virtual and In-Person Attendees)

  • This session will discuss regulatory pathways for recombinantly manufactured peptide products and strategies for immunogenicity risk mitigation using an in vitro approach. More specifically, immunogenicity risk assessment of host cell proteins as potential contaminants in peptide drug products. Also discussed in this session will be alternative models for immunogenicity risk assessment.

Session 5: Synthetic Oligonucleotide Therapeutics

Format: Presentations and a Panel Discussion Q&A (Virtual and In-Person Attendees)

  • This session will discuss the challenges of characterization of sequence-related impurities for oligonucleotide drug products and considerations of structure of such impurities and immunogenicity risk. Also discussed will be the role of innate immune response modulating impurities (IIRMIs) in the overall risk assessment.

Session 6: In-Person Activities (Working Session)

Format: Small Group Working Sessions (In-Person Attendees Only)

Small group working sessions will involve structured activities for in-person attendees, focusing on the areas discussed during Day 2 of the workshop. First, groups will consider the regulatory challenges for recombinantly produced peptide products and possible in vitro strategies for assessing the risk of host cell protein impurities that may be present in such products. Second, the challenges associated with analytical characterization of oligonucleotide-related impurities and the immunogenicity risk assessment of such impurities and other potential IIRMIs will be discussed.

The workshop will be held at the Universities at Shady Grove (USG).

Address: Ballroom (please follow signs), 9630 Gudelsky Drive Building II, Rockville, MD 20850

  • Travel from local airports to Rockville, Md. (The Universities at Shady Grove (USG)) will require an Uber or Lyft, which is by far the best way to obtain car service.
  • As there is road traffic in the region, the fastest way to the Shady Grove campus is the DCA airport, then taking the Metro subway from the airport to Shady Grove, then taking Uber or Lyft. Alternatively, fly into any WAS airport and take Uber or Lyft. If flying into BWI airport, we suggest taking Uber or Lyft to USG.
  • The Metro subway serves DCA and IAD airports, which connects with the Shady Grove stop on the red line. If flying into IAD, taking the Metro will save some cost, but will probably take extra time, even if traffic is heavy.
