Filter by:This randomized, double-blind multiple ascending dose study will evaluate the safety and tolerability, pharmacokinetics and efficacy of RO4917523 in patients with Fragile X Syndrome. The patients will be randomized to receive either active drug or placebo. The anticipated time on study treatment is 6 weeks. The target sample size is <100 patients.
The objectives of this study are to determine the safety and tolerability of single oral doses of STX107 and to determine basic pharmacokinetic (PK) parameters following single oral doses of STX107 when administered via an oral suspension
The purpose of this study is to investigate the effectiveness and tolerability of riluzole in adults with Fragile X Syndrome.
The subjects that meet the inclusion and exclusion criteria and consent to participate in protocol 22003 will be offered participation in 22003A which will evaluate secreted protein before and after treatment with STX209 and placebo to determine if they correlate with effectiveness of treatment or susceptibility to treatment with STX209. These same subjects will also be asked to contribute a blood sample for DNA (deoxyribonucleic acid) collection. The investigators will study the DNA to determine if STX209 works better in people with specific gene variations, or to find new gene variations that predict how well STX209 works.
Measurement of metabotropic glutamate receptor type 5 (mGluR5) binding capacity in the brain, may be a valuable tool in the early detection, understanding, or evaluation of Parkinson disease (PD), Huntington disease (HD), Fragile X syndrome (FXS), Autism Spectrum Disorder(ASD), Alzheimer's Disease(AD), and subjects with mild cognitive impairment (MCI). The goal of this study is to assess [18F]F-PEB positron emission tomography (PET) imaging as a tool to detect mGluR5 density in the brain of PD, HD, FXS ASD, AD, and MCI research participants and similarly aged healthy subjects.
Fragile X Syndrome (FXS) is the most common known inherited form of mental impairment, developmental disability and autism. Minocycline is an antibiotic that has recently been used to treat the mouse model for Fragile X, and was found to reverse the structural abnormalities that are seen their brain cells. The purpose of this research study is to determine if minocycline is an effective treatment for patients with fragile X syndrome (FXS).
The subjects that meet the inclusion and exclusion criteria and consent to participate in protocol 22001 will be offered participation in 22001A which will evaluate secreted protein before and after treatment with STX209 and placebo to determine if they correlate with effectiveness of treatment or susceptibility to treatment with STX209. These same subjects will also be asked to contribute a blood sample for DNA (deoxyribonucleic acid) collection. The investigators will study the DNA to determine if STX209 works better in people with specific gene variations, or to find new gene variations that predict how well STX209 works.
The study objective is to explore the efficacy, safety and tolerability of STX209 for treatment of irritability in subjects with FSX. We hypothesize that STX209 will improve irritability and other typical problem behaviors associated with fragile X syndrome. We also hypothesize that STX209 will be safe and well tolerated.
This study will evaluate the safety, tolerability and efficacy of multiple doses of AFQ056 in patients with Fragile X Syndrome. The dose range will be 50 to 150 mg b.i.d. The primary read-out of efficacy is reduction in Aberrant-Behavior Checklist score.
This is an open label exploratory study to investigate the safety and effects of a single dose of NPL-2009(50 mg - 150 mg) on Prepulse Inhibition (PPI) Tests and Continuous Performance Tasks (CPT) in adults with Fragile X Syndrome
