You've found the most recent data we have available! The results are very encouraging, particularly that none of the infants involved displayed any negative effects. The absolute infant dose found here (absolute infant dose of 0.024 mg/kg/d) is quite low. While there still isn't much data to go off of, these large molecule drugs don't pass into the breastmilk to a large degree. Even further, there is a reason Ocrevus is given as an injection--it isn't absorbed well orally. This protects the infant from any Ocrevus that does get in your milk. In most situations with a healthy 3-month-old, breastfeeding on Ocrevus is feasible with your pediatrician's blessing.
