Summit Completes Enrolment of PhaseOut DMD, a Phase 2 Clinical Trial of Ezutromid in Patients with DMD
OXFORD, United Kingdom, May 15, 2017 (GLOBE NEWSWIRE) -- Summit Therapeutics plc (NASDAQ:SMMT) (AIM:SUMM), the drug discovery and development company advancing therapies for Duchenne muscular dystrophy (‘DMD’) and Clostridium difficile infection, today announces that it has completed enrolment in PhaseOut DMD, a Phase 2 proof of concept clinical trial of the utrophin modulator, ezutromid, in patients with DMD. PhaseOut DMD aims to provide proof of concept for ezutromid through measures of a number of endpoints related to muscle structure, health and function. The Company believes the trial could provide valuable insight into utrophin modulation as a potential disease-modifying treatment for all patients with DMD, regardless of the underlying dystrophin mutation.
With the dosing of the last patient in the trial, the Company has triggered a $22 million milestone payment as part of the Company’s licence and collaboration agreement with Sarepta Therapeutics, Inc.
“Completing enrolment in PhaseOut DMD is a major step in the development of ezutromid as we seek to understand if this utrophin modulator has positive effects on muscle structure leading to changes in muscle health and function in patients with DMD,” said Dr David Roblin, Chief Operating Officer and President of R&D of Summit. “Utrophin modulation has potential as a universal treatment option for patients with DMD, and we look forward to the 24-week data readout expected in the first quarter of 2018.”
PhaseOut DMD is a 48-week open-label trial that has enrolled 40 patients at sites in the UK and the US. As part of the trial, each patient undergoes two biopsies, a baseline biopsy on enrolment and a second either at 24 or 48 weeks. In the first quarter of 2018, Summit expects to report 24-week biopsy analysis from approximately 20 patients, as well as 24-week MRI and functional data from all 40 patients enrolled in the trial. Top-line data from the complete 48-week trial are expected in the third quarter of 2018.

About Utrophin Modulation in DMD
DMD is a progressive muscle wasting disease that affects around 50,000 boys and young men in the developed world. The disease is caused by different genetic faults in the gene that encodes dystrophin, a protein that is essential for the healthy function of all muscles. There is currently no cure for DMD and life expectancy is into the late twenties. Utrophin protein is functionally and structurally similar to dystrophin. In preclinical studies, the continued expression of utrophin has a meaningful, positive effect on muscle performance. Summit believes that utrophin modulation has the potential to slow down or even stop the progression of DMD, regardless of the underlying dystrophin gene mutation. Summit also believes that utrophin modulation could potentially be complementary to other therapeutic approaches for DMD. The Company’s lead utrophin modulator, ezutromid, is an orally administered, small molecule. DMD is an orphan disease, and the US Food and Drug Administration (‘FDA’) and the European Medicines Agency have granted orphan drug status to ezutromid. Orphan drugs receive a number of benefits including additional regulatory support and a period of market exclusivity following approval. In addition, ezutromid has been granted Fast Track designation and Rare Pediatric Disease designation by the FDA.
About the Licence and Collaboration Agreement with Sarepta Therapeutics, Inc.
In October 2016, Summit announced a licence and collaboration agreement with Sarepta. This granted Sarepta exclusive commercial rights to the Company’s utrophin modulator pipeline, including ezutromid, in Europe, Turkey and the Commonwealth of Independent States, with an option over specific countries in Central and South America. Summit retains commercialisation rights in all other countries, including the US and Japan. Under the agreement, Summit received an upfront payment and is eligible to receive development, regulatory and sales milestones related to its utrophin modulator pipeline, including ezutromid, as well as royalties on net sales in the licensed territories. For further details, please refer to earlier RNS announcements and/or Summit’s filings with the Securities and Exchange Commission.
