Rezurock inhibits the action of ROCK-2 in cells, thereby blocking the signaling and anti-inflammatory pathways induced by ROCK-2. Rezurock is used to treat chronic graft-versus-host disease (cGvHD) in adults and children over 12 years of age after failure of at least 2 prior systemic therapies.

Rezurock is in the form of tablets, taken orally once a day after meals with a full glass of water. The patient should swallow the Rezurock tablet whole instead of crushing, chewing, or biting the tablet. Patients should take Rezurock at the same time each day, 24 hours apart.
