Expertise Across Emerging Oncology Modalities

Bioconjugates are creating new and more effective treatment options for patients, particularly in oncology. Abzena supports ADCs, bispecific ADCs, dual-payload ADCs, antibody-oligonucleotide conjugates (AOCs), and radiopharmaceutical conjugates (RDCs), alongside other innovative modalities, helping innovators overcome development complexity and accelerate clinical success.

Antibody-Drug Conjugates (ADCs)

ADCs have become one of the most powerful modalities in targeted oncology, delivering potent therapies directly to cancer cells while minimizing damage to healthy tissue. Abzena provides end-to-end ADC development and manufacturing solutions spanning antibody optimization, linker-payload design, bioconjugation, analytical development, and GMP manufacturing.

Key strengths include:

  • 400+ ADCs produced globally.
  • Proprietary ThioBridge® conjugation technology for precise, site-specific conjugation and enhanced stability.
  • Early de-risking and optimization to improve the likelihood of clinical success.

Antibody-Oligonucleotide Conjugates (AOCs)

In oncology, AOCs offer the potential to directly target cancer-driving genes while reducing off-target effects through antibody-mediated delivery. By combining the specificity of antibodies with technologies such as siRNA and antisense oligonucleotides, AOCs create new opportunities to address disease mechanisms that may be difficult to reach with conventional therapeutics.

Key strengths include:

  • End-to-end AOC development from design to GMP manufacture.
  • 20+ years of bioconjugation expertise across antibodies and oligos.
  • Scalable manufacturing and analytics for clinical-ready AOCs.

Degrader-Antibody Conjugates (DACs)

Degrader-Antibody Conjugates (DACs) represent an emerging class of targeted therapeutics that combine the selectivity of antibodies with the promise of targeted protein degradation. As oncology innovators explore new approaches to selectively eliminate disease-driving proteins, DACs are increasingly being investigated as a next-generation bioconjugate modality.

Key strengths include:

  • Extensive experience in antibody conjugation and complex biotherapeutics.
  • Advanced linker & payload design that optimizes degrader delivery, stability, and efficacy.
  • Supports progression from discovery through GMP production.

Bispecifics & T Cell Engagers (TCEs)

TCEs represent a new generation of antibody-based immunotherapies designed to redirect immune cells to selectively destroy cancer cells. Abzena’s expertise in bispecifics and multispecifics, molecular engineering, and platform-based development strategies helps developers create safer, scalable, and clinically viable immunotherapy candidates.

Key strengths include:

  • Deep bispecific design expertise across multiple formats.
  • Data-led molecular engineering for optimized TCE design.
  • Integrated development and manufacturing from discovery to clinic.

Case Study 1: Complex Biologics Development for a Bispecific Fusion Nanobody

A clinical-stage life sciences company developing conditionally acting medicines for cancer partnered with Abzena to advance a VHH camelid nanobody with cytokine fusion. Using the AbZelectPRO™ cell line development platform, Abzena delivered a highly stable, high-producing cell line for the bispecific oncology program within a fully integrated development environment.

Key Outcomes

  • Stable, high-producing cell line generated for a complex oncology biologic
  • Streamlined development through a single integrated partner

Case Study 2: Anti-PD1 Antibody Discovery Program

Through its B Cell discovery platform, Abzena supported an Anti-PD1 antibody discovery program designed to accelerate candidate identification. The approach delivered reduced timelines and earlier access to high-quality characterization data, enabling the generation of a diverse panel of recombinant antibodies for further development.

Key Outcomes

  • Faster discovery timelines
  • Earlier decision-making through improved candidate characterization

Case Study 3: Advancing ADC Development Through Mechanistic Understanding

Working with Sartorius, Abzena demonstrated how integrated live-cell imaging can provide deeper insight into ADC mechanisms of action. Using clinically validated ADCs as benchmarks, the team generated kinetic data that revealed important mechanistic differences and supported more informed candidate selection decisions.

Key Outcomes

  • Improved understanding of ADC pharmacology
  • Enhanced early-stage candidate selection and program de-risking

Case Study 4: ThioBridge® Technology for Next-Generation ADCs

Abzena’s proprietary ThioBridge® platform has been used to support ADC programs transitioning from preclinical development into clinical manufacturing.
