Understanding the immune response to therapeutic antibodies: Insights from recent research

Therapeutic antibodies have transformed modern biopharmaceuticals, providing targeted and highly specific treatments for a range of diseases, including oncology, autoimmune disorders, and infectious diseases.

However, immunogenicity concerns, particularly the development of anti-drug antibodies (ADAs), continue to pose challenges, affecting the pharmacokinetics (PK), efficacy and safety profiles of these biologics.

In this post, we delve into the key insights from a recent editorial in Frontiers in Immunology on the immune response to therapeutic antibodies and explore how Svar Life Science can help overcome these challenges.

Understanding the immune response to therapeutic antibodies: Insights from recent research

Therapeutic antibodies have transformed modern biopharmaceuticals, providing targeted and highly specific treatments for a range of diseases, including oncology, autoimmune disorders, and infectious diseases.

However, immunogenicity concerns, particularly the development of anti-drug antibodies (ADAs), continue to pose challenges, affecting the pharmacokinetics (PK), efficacy and safety profiles of these biologics.

In this post, we delve into the key insights from a recent editorial in Frontiers in Immunology on the immune response to therapeutic antibodies and explore how Svar Life Science can help overcome these challenges.

The editorial highlights several studies with the following crucial points:

  1. Advances and Challenges: Therapeutic antibodies represent one of the most successful classes of biologic drugs, playing a critical role in precision medicine and targeted immunotherapy. However, the development of anti-drug antibodies (ADAs) remains a significant challenge, as highlighted by a recent FDA guidance stating the necessity for clear reporting on product labels regarding the incidence and clinical significance of ADAs.
  1. Impact of ADAs: ADAs can trigger neutralizing or non-neutralizing immune responses, with potential consequences ranging from reduced drug efficacy to severe immune-related adverse events, particularly when they cross-react with endogenous proteins.

  2. Innovative Techniques: The field of therapeutic antibody engineering is rapidly advancing with innovative immunogenicity mitigation strategies, such as nanobody-based therapeutics, framework shuffling, and complementary determining region (CDR) aimed at improving safety and efficacy.

  3. Chemical Modifications: While antibody humanization and sequence optimization have helped mitigate immunogenicity, post-translational modifications such as PEGylation and glycosylation can introduce novel immunogenic epitopes, necessitating comprehensive immunogenicity risk assessment through specialized assays.
5. Comprehensive Assessments
Given the multifactorial nature of immunogenicity, there is an increasing demand for integrated bioanalytical platforms capable of detecting, characterizing, and quantifying ADAs to support regulatory-compliant risk assessments.
A trend towards risk-centered approaches that involve multiple assays is emerging, with pharmacokinetic (PK) assays serving as a basis for characterizing the ADA response to T-cell engager bispecific antibodies.

6. Preclinical and Clinical Studies: Evaluating immunogenicity risks in preclinical studies is crucial. Research has shown that different administration routes can lead to reduced ADA responses and that cytokine domains can significantly affect these responses.

7. Role of Dendritic Cells: ADA production is initiated by antigen uptake by dendritic cells, which present peptide fragments to T cells, triggering B-cell activation and ADA production.

8. In Vitro Methods: Assays like MHC-II-associated peptide proteomics (MAPPs) are employed to assess the immunogenic potential of therapeutic antibodies, taking into account geographical differences in HLA alleles.
