“CAB was negative for immunosuppression in a T-cell–dependent antibody response (TDAR) study in rats, and was not associated with skin sensitization, skin irritation, ocular irritation, or phototoxicity.”
Low brain penetration; detected in rat fetal tissue
“Very small amounts were also detected in the brain, indicating that low levels of CAB cross the blood–brain barrier. CAB was also detected in fetal tissue in an investigative toxicokinetic (TK) study in pregnant rats.”
Injection-site reactions with the long-acting IM formulation
“The main findings in pivotal local tolerance studies in dogs and minipigs via IM injection of RPV LA were injection site findings, which have been characterized in human subjects and are monitorable.”
