Further study details as provided by Summit Therapeutics:

Primary Outcome Measures:
  • Change in MRI leg muscle parameters [ Time Frame: Baseline, Weeks 12, 24, 36 and 48 ]
  • SMTC1100 (ezutromid) plasma concentrations [ Time Frame: Pre-dose and post-dose at Weeks 1, 4, 8, 12, 24, 36 and 48 ]

Secondary Outcome Measures:
  • Change in utrophin membrane staining via quantifiable imaging of immunostained biopsy sections [ Time Frame: Baseline and at either Week 24 or 48 ]
  • Change in muscle regenerating fibres by measuring via muscle biopsy a combination of fibre size and neonatal myosin positivity [ Time Frame: Baseline and at either Week 24 or 48 ]
  • Treatment emergent adverse events (AEs) and safety laboratory abnormalities [ Time Frame: Through study completion of 48 weeks ]

Estimated Enrollment: 40
Study Start Date: June 2016
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Open Label Treatment Arm
SMTC1100 (ezutromid) oral suspension
Drug: ezutromid
oral suspension
Other Name: SMTC1100

Detailed Description:

This is a Phase 2, open-label, study to assess the activity and safety of utrophin modulation with SMT C1100 (ezutromid) 2500 mg administered orally bid in ambulatory paediatric male subjects with DMD. Approximately 40 subjects with DMD will be enrolled in this study.

This study will be conducted in a multi-centre setting in both the United Kingdom and the United States of America and comprises of a Screening and Baseline Phase of up to 28 days, a 48-week open label Treatment Phase and a 30-day Safety Follow up Phase.
