Summit Granted US Patent for Utrophin Modulator SMT C1100 in Treatment of DMD
Oxford, UK, 7 August 2013 - Summit (AIM: SUMM), a drug discovery and development company advancing therapies for Duchenne Muscular Dystrophy ('DMD') and C. difficile infection, announces that the United States Patent and Trademark Office has issued patent number 8,501,713 that protects the use of SMT C1100 in treating the fatal muscle wasting disease DMD.
The patent, entitled "Drug Combinations for the Treatment of Duchenne Muscular Dystrophy," covers the combination use of SMT C1100, the small molecule utrophin modulator drug, with corticosteroids such as prednisolone and deflazacort. It provides an exclusivity period until at least February 2029.
Corticosteroids are commonly used in patients to slow the progression of DMD. Summit has shown in the widely used preclinical efficacy model that there is a significant benefit in using prednisolone in combination with SMT C1100. Results from a preclinical fatigue study, analogous to the 6 minute walk distance test used in DMD patient trials, demonstrated that the combined treatment completely protected against fatigue with the treatment group able to travel three and half times the distance of the untreated group. These data have been published in the peer reviewed scientific journal PLoS ONE (Ref: Tinsley et al, Volume 6, Issue 4, May 2011).
"The grant of this US patent covering the use of SMT C1100 in combination with steroids forms part of our broader estate protecting the intellectual property rights of our utrophin modulation programme for DMD," commented Glyn Edwards, Chief Executive Officer of Summit. "This patent estate provides Summit with a commercial advantage from which to exploit the promise of our utrophin modulation programme for the treatment of this devastating disease."
About DMD and Utrophin Modulation
DMD is a progressive muscle wasting disease that affects around 1,500 boys and young men in the UK. It is caused by different genetic faults in the gene that encodes dystrophin, a protein that is essential for the healthy function of muscles. There is no cure and life expectancy is around the mid-twenties. Utrophin protein is the functional equivalent of dystrophin and non-clinical studies have shown it can substitute for dystrophin to maintain the healthy function of skeletal and cardiac muscle. Utrophin modulation has the potential to slow down or even stop the progression of DMD regardless of the dystrophin mutation. Importantly it is also expected to be complementary to other DMD therapeutic approaches in development.
