Summit Corporation and Children's National Medical Center Enter Utrophin Biomarker Collaboration for Duchenne Muscular Dystrophy  
2/6/2013 10:31:46 AM

Oxford, UK, 6 February 2013 – Summit (AIM: SUMM), a drug discovery and development company advancing therapies for Duchenne Muscular Dystrophy (“DMD”) and C. difficile infections, announces that it has entered into a collaboration with Dr Yetrib Hathout from Children’s National Medical Center in Washington DC, for the development of utrophin biomarkers for DMD. The collaboration is being financially supported by a grant from the Foundation to Eradicate Duchenne and is part of a comprehensive biomarker programme being undertaken by Summit to advance its utrophin modulator programme for DMD. In late 2012, Summit reported that in a Phase 1 trial in healthy volunteers, its lead candidate SMT C1100 was safe and well-tolerated.

“We are delighted to be working with Dr Hathout on developing new biomarkers that will help advance our understanding of DMD while supporting the progress of Summit’s utrophin modulator programme,” commented Glyn Edwards, Chief Executive Officer of Summit. “Developing biomarker indicators capable of accurately measuring utrophin protein levels in muscle will be vital in helping to confirm the activity of our clinical candidate SMT C1100 in future patient trials. We thank the Foundation to Eradicate Duchenne for their continuing support in advancing this important medical research.”

Joel Wood, President of the Foundation to Eradicate Duchenne added, “We are committed to ensuring that urgently needed treatments have the best possible chance of successfully progressing through clinical trials. As such, we are pleased to provide funding to support Summit’s utrophin modulation programme, which is a novel and promising approach for treating all genetic forms of DMD.”

DMD is caused by genetic mutations that prevent patients from making the structural protein dystrophin, which leads to progressive muscle wasting and is ultimately fatal. Summit is pioneering utrophin modulation to stimulate production of utrophin, a functionally similar protein to dystrophin that is expressed in foetal and regenerating muscle, and which has the potential to restore and maintain healthy muscle function. This disease modifying approach would benefit all DMD patients, regardless of the underlying genetic fault causing their illness. SMT C1100 is the Company’s leading utrophin modulator drug and successfully completed a Phase 1 clinical trial in late 2012.

The development of new biomarkers that accurately quantify utrophin protein levels in DMD muscles will play an important role in providing evidence for the potential effectiveness of Summit’s utrophin modulator drugs in future patient clinical trials. Dr Hathout, a Principal Investigator at the Center for Genetic Medicine Research at Children’s National, will apply his expertise in cutting-edge proteomic techniques to develop a sensitive, robust mass-spectrometry based assay that can quantitatively measure utrophin protein levels in biopsies of DMD muscle. This collaboration is part of Summit’s comprehensive biomarker programme developing a range of assays that will measure biological endpoints to demonstrate muscle benefit after treatment with small molecule utrophin modulators.

About Foundation to Eradicate Duchenne

The Foundation to Eradicate Duchenne Muscular Dystrophy (‘FED’) is a non-profit organisation founded in 2002 to provide funding into research for treatments and ultimately a cure for Duchenne Muscular Dystrophy (‘DMD’). THE FED raises money to support the world’s only clinical trials network for DMD. The clinical trials network is known as CINRG and works with scientists all over the world on therapies for DMD.
