Fragile X Syndrome Clinical Trial
Official title:
A Phase II Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Fixed-Dose Study of NNZ-2566 in Fragile X Syndrome
The purpose of this study is to determine whether NNZ-2566 is safe and well tolerated in the treatment of Fragile X Syndrome in adolescent and adult males.
Fragile X Syndrome is a genetically determined neurological disorder in which affected
individuals are intellectually handicapped to varying degrees and display a variety of
associated psychiatric symptoms. Clinically, Fragile X Syndrome is characterized by
intellectual handicap, hyperactivity and attentional problems, autism spectrum symptoms,
emotional lability and epilepsy. The epilepsy seen in Fragile X Syndrome is most commonly
present in childhood, but then gradually remits towards adulthood. Physical features such as
prominent ears and jaw, and hyper-extensibility of joints are frequently present but are not
diagnostic. Intellectual handicap is the most common feature defining the phenotype.
Treatment for the disorder is symptomatic - focusing on the management of symptoms - and
supportive, requiring a multidisciplinary approach.
This study will investigate the safety and tolerability of treatment with oral administration
of NNZ-2566 at 35 mg/kg or 70 mg/kg BID in adolescent or adult males with Fragile X Syndrome.
The study also will also investigate measures of efficacy during treatment.
