DMD: Eteplirsen Results Very Encouraging at 48 Weeks

Editor's note (Oct. 3, 2012): Please read A Closer Look at the 48-Week Eteplirsen Trial Results for a more in-depth discussion of the phase 2b trial in boys with Duchenne MD.

Study of Tadalafil in BMD Revised, Reopened

Update (Nov. 9, 2012): This story has been updated to reflect that recruitment for this study ends Dec. 31, 2012.

An MDA-supported, short-term trial of the vasodilating drug tadalafil (Cialis) in teens and men with Becker muscular dystrophy (BMD) has undergone some minor restructuring and is now open to 12 additional participants.

MDA Muscle Symposium: Newborn Screening in DMD

Update (Feb. 8, 2013): Longtime MDA grantee Jerry Mendell, who directs the Center for Gene therapy at Nationwide Children's Hospital in Columbus, Ohio, published Report of MDA Muscle Disease Symposium on Newborn Screening for Duchenne Muscular Dystrophy in Muscle & Nerve, Feb. 8, 2013.

DMD Briefs: Stopping Inflammation on Earth and in Space

Inflammation— the immune system's first line of defense in tissue that's been damaged by injury or infection — is a good example of a process that's a good thing up to a point and under certain circumstances and a bad thing in excess or under the wrong circumstances.

Sarepta Issues ‘Open Letter’ Explaining Development of Eteplirsen for DMD

In July 2012, Sarepta Therapeutics announced encouraging interim results for its phase 2b trial of eteplirsen, an experimental exon-skipping drug in development to treat Duchenne muscular dystrophy (DMD) caused by specific mutations in the dystrophin gene.

MDA Applauds Congress for Including Two Neuromuscular Diseases in Pediatric Research Bill

In July, days before the U.S. House of Representatives and Senate went into recess, bipartisan legislation was introduced in both houses to strengthen research into pediatric diseases.

MDA Commits $10.7 Million to Neuromuscular Disease Research

The Muscular Dystrophy Association has awarded 33 new grants totaling $10,684,481 to fund research projects focused on uncovering the causes of, and developing therapies for, neuromuscular disease.

MDA's Board of Directors reviewed and approved the new grants based on recommendations from the Association's Scientific and Medical Advisory Committees, and the grants took effect Aug. 1.

DMD Research Briefs: Exon Skipping Advances in Trials, Lab

Exon skipping is an experimental therapeutic strategy in which regions — exons— of a gene are targeted and blocked ("skipped") by laboratory-designed molecules. The goal is that the remaining genetic instructions will lead to production of a shorter but still-functional protein.

DMD/BMD — Daniel Michele, Ph.D.

Daniel Michele, associate professor in the department of molecular and integrative physiology at the University of Michigan in Ann Arbor, was awarded an MDA research grant totaling $364,965 over three years to study the underlying mechanisms of muscle weakness and muscle fatigue in Duchenne (DMD) and Becker (BMD) muscular dystrophies.

Survey Examines Newborn Screening for Neuromuscular Disease

MDA is conducting a survey designed to assess the experiences of parents in the United States whose babies underwent newborn screening at the time of birth, with an eye toward the future possibility of newborn screening tests being recommended for certain neuromuscular diseases in which therapy development is advancing rapidly.
