Ezutromid (SMTC-1100) is a small molecule utrophin upregulator. Ezutromid was identified from an iterative analoging approach from initial hits identified using a human muscle-specific utrophin A promoter cell-based assay. It increases both utrophin RNA and protein resulting in a significant reduction in dystrophic symptoms and increased muscle function in dystrophin-deficient mdx mice ( a mouse model of Duchenne muscular dystrophy (DMD)). Ezutromid was deemed safe and well tolerated in a Phase 1a healthy volunteer study and successfully completed a Phase 1b study in DMD boys. Summit Therapeutics is developing Ezutromid for the treatment of Duchenne muscular dystrophy.

Sample Use Guides

A multicenter, Phase 1 study (NCT02056808) enrolled 12 pediatric patients with Duchenne muscular dystrophy, divided equally into three groups (A-C). Group A were given 50 mg/kg on Days 1 and 11, and 50 mg/kg bid on Days 2 to 10. Group B and C received 100 mg/kg on Days 1 and 11; Group B and Group C were given 100 mg/kg bid and 100 mg/kg tid, respectively, on Days 2 to 10.
Route of Administration: Oral
In vitro dosing of human myoblasts with Ezutromid (SMT C1100) leads to a 25% increase in utrophin mRNA when compared to vehicle-only dosing after three days of treatment. Treatment of human DMD cells with SMT C1100 lead to a 2-fold increase in utrophin protein levels at an optimal concentration of 0.3 µM after 3 days of treatment.
