MAKING A DIFFERENCE IN ADC
WITH GEMINIMAB

At Syndivia, we are dedicated to advancing treatment options for cancer patients through our innovative GeminiMab Technology. This platform enables the creation of site-specific antibody-drug conjugates (ADCs) in the hinge region, ensuring optimal drug-to-antibody ratios (DAR), including the unique site-specific DAR1. Our approach leverages these targeted ADCs' distinct properties to significantly enhance antitumor efficacy, offering a powerful and well-tolerated therapeutic option for cancer patients.

THE SCIENCE

GEMINIMAB ADC PLATFORM

Bringing site-specificity to the hinge: GeminiMab is the first and only platform that allows for hinge-region site-specific conjugation of native antibodies. It enables unprecedented simplicity and scope in creating efficient and well-tolerated antibody conjugates with optimal drug-to-antibody ratios (DAR), including unique DAR1, DAR2, and DAR4 hinge region site-specific ADCs.

GeminiMab eliminates the need for enzymes, antibody sequence modification, or specific pretargeting units to achieve site specificity. The resulting conjugates preserve the native glycosylation profile, and maintain antibody flexibility and integrity, while ensuring the covalent linkage between antibody chains. The conjugation site is located in the safest and most clinically validated antibody hinge region, naturally concealing payload hydrophobicity and immunogenicity without requiring additional modifications or tweaks of the payload.

OPTIMAL DAR & CONJUGATION SITE

Syndivia leverages GeminiMab Technology to develop a proprietary pipeline of ADC candidates with payloads conjugated at the optimal drug-to-antibody ratios (DAR) site-specifically within the most clinically validated and efficient site on the antibody – the hinge region. This allows for the highest dosing without compromising safety. Achieved through improved tumor penetration and enhanced therapeutic efficacy, GeminiMab stands apart from other available ADC technologies.
