Mechanism of action

IO102-IO103 combines IO102 (a personalized neoantigen vaccine) with IO103 (an anti-CTLA-4 checkpoint inhibitor) to enhance anti-tumor immunity. The vaccine targets neoantigens derived from individual patient tumors, while the checkpoint inhibitor removes immune suppression, allowing T cells to mount a more robust response against cancer cells.
