huCD19 Tg mouse: reduced fertility index at both 3 and 30 mg/kg doses given weekly from 15 days before mating to GD15
“Animals that received IV doses (0, 3, or 30 mg/kg) inebilizumab weekly beginning 15 days prior to mating and through GD15 showed reduced fertility index at both dose levels.”

Safety pharmacology
No stand-alone studies; endpoints incorporated into repeat-dose toxicology studies
“Stand-alone safety pharmacology studies were not conducted for inebilizumab. Safety pharmacology endpoints were evaluated as part of the repeat-dose general toxicology studies.”

No dedicated safety pharmacology; no neurological, cardiovascular or respiratory effects in repeat-dose studies
“Dedicated safety pharmacology studies were not performed. The potential for exaggerated pharmacology on the neurological, cardiovascular, and respiratory systems was assessed through cage side observations and detailed physical examinations conducted during the repeat-dose toxicology studies.”
