Santhera to Present Long-term Efficacy Results with Idebenone in DMD at the 2019 MDA Clinical and Scientific Conference
Pratteln, Switzerland,? Santhera Pharmaceuticals (SIX: SANN) and its collaborating clinical experts present results of long-term efficacy on respiratory function outcomes in idebenone-treated patients with Duchenne muscular dystrophy (DMD) at the 2019 Muscular Dystrophy Association (MDA) Clinical and Scientific Conference held in Orlando, USA, April 13-17, 2019.
Posters presented at the MDA conference show consistent long-term efficacy data from two randomized placebo-controlled studies and their extended long-term data collections in patients treated with idebenone (Posters #7 and #9). In addition, new natural history data demonstrates the predictive value of slowing the rate of respiratory function decline on delaying time to initiation of assisted ventilation or death (Poster #11). Collectively, these data support the long-term potential of treatment with idebenone to delay the time to clinically relevant outcomes.
Poster #7: ?SYROS study ? long-term reduction in rate of respiratory function decline in patients with Duchenne Muscular Dystrophy (DMD) treated with idebenone?
Presenter: Oscar H Mayer, MD, pediatric pulmonologist and Director of the Pulmonary Function Laboratory at Children's Hospital of Philadelphia, USA
Poster #9: ?Consistent long-term effect of idebenone in reducing respiratory function decline in advanced patients with Duchenne Muscular Dystrophy (DMD)?
Presenter: Oscar H Mayer, MD
Poster #11: ?Crossing thresholds and changing rates of respiratory function decline are predictive of clinical outcomes in Duchenne Muscular Dystrophy (DMD)?
Presenter: Craig McDonald, MD, Professor and Chair, Department of Physical Medicine & Rehabilitation and Director of Neuromuscular Disease Clinics, UC Davis Health, USA
Time/place: Monday, April 15, 2019, 6pm ? 8pm, during the Networking and Poster Reception in the Exhibit Hall (on display all day).
Additionally, the new data will be presented at a Santhera hosted Industry Forum Lunch by a panel of clinical experts:
Title: ?Respiratory function decline in Duchenne muscular dystrophy: insights and evolving treatment strategies?
Presenters: Craig McDonald, MD and Oscar H Mayer, MD
Time/place: Tuesday, April 16, 2019, 12:30 ? 1:45pm, Hall Florida B-C.

In February, Santhera announced topline results from the SYROS study which demonstrated that long-term treatment with idebenone consistently reduced the rate of respiratory function loss in patients with Duchenne muscular dystrophy (DMD) for up to 6 years in a real-world setting. This long-term data further supports the potential for idebenone to modify the course of respiratory function decline in DMD and thereby delay the time to clinically relevant milestones.
The posters can be viewed here and the findings from the SYROS study will be submitted for publication in a peer-reviewed journal.
About Duchenne Muscular Dystrophy
DMD is one of the most common and devastating types of progressive muscle weakness and degeneration starting at an early age and leading to early morbidity and mortality due to respiratory failure. It is a genetic, degenerative disease that occurs almost exclusively in males with an incidence of up to 1 in 3,500 live male births worldwide. DMD is characterized by a loss of the protein dystrophin, leading to cell damage, impaired calcium homeostasis, elevated oxidative stress and reduced energy production in muscle cells. With age, progressive respiratory muscle weakness affecting thoracic accessory muscles and the diaphragm causes respiratory disease, impaired clearance of airway secretions, recurrent pulmonary infections due to ineffective cough, and eventually respiratory failure. There is currently no treatment approved for slowing loss of respiratory function in patients with DMD.
About Idebenone in Duchenne Muscular Dystrophy
Idebenone is a synthetic short-chain benzoquinone and a cofactor for the enzyme NAD(P)H:quinone oxidoreductase (NQO1) capable of stimulating mitochondrial electron transport, reducing and scavenging reactive oxygen species (ROS) and supplementing cellular energy levels.
DELOS was a Phase III, double-blind, placebo-controlled 52-week study which randomized 64 patients, not taking concomitant steroids, to receive either idebenone (900 mg/day) or matching placebo. The study met its primary endpoint, the change from baseline in peak expiratory flow (PEF) expressed as percent of predicted, which demonstrated that idebenone can slow the loss of respiratory function. Supportive data for idebenone were shown in the Phase II double-blind, placebo-controlled DELPHI study and its 2-year open-label extension study (DELPHI-E).
SYROS was a prospectively planned, retrospective collection of long-term respiratory function data from 18 patients who completed the DELOS study and subsequently received idebenone (900 mg/day) under Expanded Access Programs (EAPs). The SYROS study showed that the previously observed beneficial effect of idebenone in reducing the rate of respiratory function decline was maintained for up to six years during treatment.
