(January 7, 2018)
The FDA approved 46 new chemical drugs and three important biological drugs in 2017 after only approving 22 chemical drugs in 2016. The four drugs below were fast-tracked for approval under "priority review" status and also represent "first-in-class" innovation for the drug type. The first two are for extremely rare diseases that afflict children and received rare FDA pediatric disease priority review. The second two treat rare forms of leukemia, including a break-through gene therapy (Kymriah) that is only approved for use in children and young adults up to age 25.

Battern disease is a rare fatal inherited brain disease;
children born with the disease start showing symptoms at age 2
and many lose the ability to walk and talk at around age 6. Most
die by their teens. This drug slows the progression of loss of
ambulation so it helps the child to be able to walk longer. It
is an enzyme replacement therapy. Only 20 children are born with
the disease in the U.S. each year.
