Large-Scale Trial of Idebenone in DMD is Now Open

A large-scale, phase 3 trial of idebenone (Catena) in Duchenne muscular dystrophy (DMD) is now open at one U.S. site and several sites in Europe, under the auspices of Santhera Pharmaceuticals.

Longer Chromosome Tips Mean Better Muscle Repair in DMD mice

Dystrophin-deficient mice (known as mdx mice) have been used in experiments as a model of human Duchenne muscular dystrophy (DMD) for decades. However, scientists have long noted that mdx mice, even though they develop a disease that mimics some aspects of human DMD, fare much better than human DMD patients. Mdx mouse muscles don't deteriorate as severely, and their ability to move and maintain heart function is far better than that of humans with the disease.

Does Spirituality Influence Acceptance of Disability?

With approximately 54 million Americans living with disabilities, exploring and understanding factors that might facilitate or hinder acceptance of one’s disability may be an important area of research.

But what exactly is the relationship between religious/spiritual attitudes and acceptance or lack of acceptance of disability for people with neuromuscular disorders?

Encouraging Results in LGMD Gene Therapy Trial

Results from an MDA-supported, phase 1 study of gene therapy for the type 2D form of limb-girdle muscular dystrophy (LGMD2D) show sustained protein production from the transferred genes in two out of three trial participants six months after injection of the genes into a foot muscle.

The new results follow an announcement last year showing protein production from transferred genes in the first three participants in this trial at either six weeks or three months after the gene transfer.

Early-Life Protein, Made Too Late, Causes Trouble in FSHD

Little by little, the molecular underpinnings of facioscapulohumeral muscular dystrophy (FSHD) are yielding to scientific investigations. The latest revelations about a protein known as DUX4, announced in October, could bring a treatment for FSHD closer to the clinic.

Viagra May be Heart Helper in DMD

Results from a recent study have shown that treatment with the drug sildenafil (brand name Viagra) conferred both long-term protection against cardiac (heart) dysfunction in younger mice, and rapid reversal of heart damage in aged mice with a disease resembling Duchenne muscular dystrophy (DMD).

Intravenous AVI4658 Shows Safety, Benefit in DMD

The experimental drug AVI4658, in development by AVI BioPharma to treat Duchenne muscular dystrophy (DMD) caused by specific genetic mutations, was well tolerated and resulted in increased production of the needed dystrophin protein. Measured aspects of cardiac, pulmonary and skeletal muscle function remained stable.

Low-Dose Ataluren Shows Some Benefit in DMD/BMD

A low-dose regimen of ataluren (formerly called PTC124), an experimental drug developed by PTC Therapeutics to treat  Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) caused by a certain type of genetic mutation, is superior to a high-dose regimen or a placebo.
