ImmunoGen Announces Presentations at AACR Annual Meeting Highlighting Continued Innovation in ADCs
“ImmunoGen has in-depth expertise in all aspects of ADCs, which has
resulted in the most comprehensive toolbox of ADC technologies in the
industry,” said
Details of ImmunoGen’s poster presentations are as follows:
Title: “A new class of DNA alkylating indolino-benzodiazepine
agents (BIAs) linked with a DNA binding moiety for use with
antibody-drug conjugates (ADCs)” (abstract
#747)
Date:
Time: 1:00 –
- A new class of DNA alkylating effector molecules for use in ADC development in which an IGN (indolino-benzodiazepine) monomer subunit is connected to a DNA binding moiety (e.g., Bi-Aryl, or Bis-Aryl) are termed BIAs. BIA ADCs displayed potent, antigen-specific in vitro activity across a panel of FRα-expressing cell lines. In vivo, these ADCs demonstrated potent efficacy in xenograft models at doses well below the maximum tolerated dose.
Title: “Development of an in vivo model system to assess the
interplay between the various drivers of antibody drug conjugate (ADC)
activity” (abstract
#753)
Date:
Time: 1:00 –
- To better understand the variables that impact ADC pharmacokinetics, tolerability, bio-distribution, and efficacy, a novel, cross-reactive model system was created. An anti-murine folate receptor alpha (FRα) antibody was generated that binds to both mouse and human FRα. The model system allows experiments to be designed in a cross-reactive system to examine how modifications to the antibody, linker or cytotoxic payload impact safety, and efficacy.
Title: “Evaluation of endoglin/CD105 as a tumor vasculature
target with antibody drug conjugates” (abstract
#2900)
Date:
Time: 1:00 –
- Endoglin/CD105 is a well-acknowledged endothelial cell proliferation marker, which is strongly expressed in tumor-associated vasculature. It was evaluated as an oncology target using ADCs of an anti-CD105 antibody with potent anti-microtubule maytansinoids DM1 and DM4, and the highly potent IGN DNA-alkylating payload, DGN549. Endoglin targeted huRH105-DM and huRH105-DGN549 conjugates produced modest anti-tumor activity and therapeutic indices in rat models.
