DIMA's Solution to Drive ADC Excellence

ADCs (Antibody-Drug Conjugates) combine the targeted precision of monoclonal antibodies with the potent impact of small-molecule cytotoxic drugs. This transformative approach not only advances the accuracy of cancer treatment but also minimize the undesired side effects associated with traditional therapies. The key to successful ADC development lies in the selection of the right antibody molecules, a pivotal factor in ensuring the efficacy and safety of these groundbreaking therapies.

Specific Cell Killing by Anti-GPRC5D Antibodies Conjugated with MMAE
In this experiment, three cell types were tested: K562 (negative control, left), K562-GPRC5D (positive cells, center), and H929 (GPRC5D-expressing natural cell line, right). The black and red curves represent MMAE-conjugated anti-GPRC5D antibodies (Ab1/2), showing specific killing of GPRC5D-positive cells. The blue curve represents MMAE-conjugated anti-GPRC5D positive control antibodies, and the green curve represents MMAE-conjugated IgG negative control. The data demonstrates the specific cytotoxicity of anti-GPRC5D antibodies against GPRC5D-positive cells following MMAE conjugation.

Cross-Reactivity Analysis of GPRC5D Candidate Antibodies with Cyno and Mouse GPRC5D Positive Cells Using FACS

In this study, we assessed four distinct cell types: 293T-hu GPRC5D, 293-cyno GPRC5D, 293-mouse GPRC5D, and 293T-negative control. The negative control, 293-PTT5 cells, lacked overexpressed GPRC5D proteins, while the other cells contained overexpressed GPRC5D proteins from human, cyno, and mouse species. We employed candidate antibodies, including G01~G09 (humanized antibodies developed by DIMA Bio) and G00 (a humanized antibody molecule developed by Eureka Therapeutics), to interact with these four cell types using FACS. Our data clearly reveals that G00, G05, G07, and G09 antibodies exhibit cross-reactivity with Cynomolgus Monkey GPRC5D, while the G00 antibody displays cross-reactivity with Mouse GPRC5D.
