Inhibited primary antibody responses to some antigens, attributed to BTK role in B cells
“Remibrutinib inhibited primary antibody responses to certain, but not all, tool antigens in rodent pharmacology studies at pharmacologically relevant exposure, considered related to the role of BTK in B cells.”
Broad tissue distribution except brain, eye lens, spinal cord and white fat
“A single oral dose of remibrutinib resulted in broad distribution in all tissues except for the brain, lens of the eye, spinal cord, and white fat, with a Tmax of 0.5 to 8 hours.”
Infection and bleeding risk from inhibited antibody responses and platelet function
“Important potential risks at pharmacologically relevant exposure are related to effects of remibrutinib on primary antibody responses (potential risks of infection, impact on at least some antibody responses) as well as on specific platelet functions (potential risk of bleeding).”
