METHODS FOR TREATING HETEROTOPIC OSSIFICATION

摘要

The invention describes dosing regimens for treating subjects with fibrodysplasia ossificans progressiva characterized by a quiescent period and a non-quiescent period, wherein a therapeutically effective amount of palovarotene is administered to the subjects during the non- quiescent period, little or no palovarotene is administered to the subjects during the quiescent period, and imatinib is administered to the subjects during the quiescent period and optionally during the non-quiescent period. The dosing regimens can reduce heterotopic ossification, reduce the number of flare- ups, and/or reduce the severity of flare-ups in subjects suffering from fibrodysplasia ossificans progressiva.
