Mechanism of action

MGd irreversibly binds to BTK, a key enzyme in B-cell receptor signaling, preventing downstream activation of survival and proliferation pathways. This mechanism is particularly effective in B-cell malignancies where BTK signaling is critical for tumor cell survival. The drug has demonstrated clinical activity in chronic lymphocytic leukemia and other lymphoid malignancies.
