Summit is a leader in the field of utrophin modulation. Our most advanced utrophin modulator, ezutromid (SMT C1100), is in a Phase 2 clinical trial called PhaseOut DMD. PhaseOut DMD aims to provide proof of concept for ezutromid and utrophin modulation by measuring muscle fat infiltration, as well as by measuring utrophin protein and muscle fibre regeneration in muscle biopsies. Further information on this trial is available at: . We also have an online resource for the Duchenne community, which includes answers to frequently asked questions on our utrophin programme and clinical trials: .

Patients with Becker muscular dystrophy have an abnormality in dystrophin, but unlike patients with Duchenne muscular dystrophy, some dystrophin is present.

Muscular dystrophies, of which Duchenne and Becker are two types, are characterized by progressive skeletal muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue. Because Becker muscular dystrophy has dystrophin (albeit abnormal), the progression of muscle weakness is slower, with the diagnosis typically made after age 8 years. Similar to patients with Duchenne muscular dystrophy, patients with Becker muscular dystrophy have pseudohypertrophy of the calves, markedly increased creatine kinase levels, and X-linked transmission of the condition.

Incorrect Answers:
Answer 2:This answer choice describes Spinal muscular atrophy. These patients have proximal muscle weakness, but the onset of weakness occurs earlier in childhood. These patients also have absent deep tendon reflexes and fasciculations, but pseudohypertrophy is absent and creatine kinase levels are normal.
Answer 3: This answer choice describes Emery-Dreifuss dystrophy. Patients with Emery-Dreifuss dystrophy may have a similar clinical picture to Becker’s muscular dystrophy, but pseudohypertrophy is absent and creatine kinase levels are only mildly elevated. In addition, neck extension, elbow flexion, and ankle equinus contractures develop at an early age.
Answer 4: This answer choice describes Guillain-Barre syndrome. This is a condition associated with results from postinfectious demyelination of the peripheral nerves. These patients have the acute onset of weakness, hypotonia, and areflexia; creatine kinase levels are normal.
Answer 5: This answer choice describes Duchenne muscular condition is primarily differentiated from Becker's muscular dystrophy by the complete absence of dystrophin, and a more severe disease course.

At the start of the year, PPMD made its biggest investment ever -- $ to Jerry Mendell at Nationwide Children’s Hospital -- for a Phase 1 Safety trial of gene therapy in Duchenne. This new publication of data showing that the technology works very well in dogs gives us added evidence that gene therapy is ready to go into humans and supports our decision to invest heavily in this approach. While dogs and humans are not exactly the same, these results are so very encouraging. We look forward to working with Dr. Mendell and his team at Nationwide and Sarepta, our co-investors, to move this trial forward.

Mercier et al. (2013) reviewed the features of 26 female carriers of pathogenic mutations in the DMD gene who were referred for symptoms related to the disorder before 17 years of age. Five had a Duchenne-like phenotype with loss of ambulation before age 15 years, 13 had a Becker-like phenotype with muscle weakness but persistence of ambulation after age 15 years, and 8 had exercise intolerance. Initial symptoms included significant muscle weakness (88%), mostly affecting the lower limbs, or exercise intolerance (27%). Cardiac dysfunction was present in 19%, and cognitive impairment in 27%. Cognitive impairment was associated with mutations in the distal part of the gene. Muscle biopsy showed dystrophic changes in 83% and mosaic immunostaining for dystrophin in 81%. The X-chromosome inactivation pattern was biased in 62% of cases. Mercier et al. (2013) concluded that carrier females may have significant symptoms of the disorder.
