Arbaclofen – Will it help kids/adults with Myotonic Dystrophy?

While poking around looking for solutions and help in the autism area I found a lot of help and support. And I found a new drug that is being tested now in Phase II studies. Its being tested for a sister disease that has a lot in common with Myotonic Dystrophy. Fragile X is a triple repeat disease and has some symptoms similar to myotonic dystrophy kids.  Fragile X syndrome (FXS) is a genetic condition that causes intellectual disability, behavioral and learning challenges and various physical characteristics. Though FXS occurs in both genders, males are more frequently affected than females, and generally with greater severity.

Both of these diseases are single gene cause of mental retardation  and autism. Perhaps the drug that treats one may be applicable to the other.

The good news is that there is a drug in late stage development that might help with autism in kids with myotonic dystrophy. This drug is called arbacofen and has been successfully tested in not only in kids with fragile X but also in other kids with autism as well. The outcome is promising and the studies are continuing. Its fairly advanced with studies in the Phase IIb, which means they are getting close to commercialization.

What is a Possible Cause of Autism?

In doing a little digging about autism and myotonic dystrophy, Fragile X is a disease that pops right to the top of the screen. This is also a triplet expansion disease and it has a couple of similarities especially to some of the childhood forms of myotonic dystrophy. Fragile x causes mental retardation (Global developmental delay) as well as many of the kids have Autism or Autism spectrum disorder. Here is a review of Autism and Fragile X
