OBJECTIVE To confirm the efficacy and safety of recombinant human alpha-L-iduronidase (laronidase) in patients with mucopolysaccharidosis I (MPS I). STUDY DESIGN This was a randomized, double-blinded, multinational study of 45 patients with MPS I administered 100 U/kg (0.58 mg/kg) laronidase, or placebo intravenously weekly for 26 weeks. The coprimary(More)
Research on animal models of fragile X syndrome suggests that STX209, a γ-aminobutyric acid type B (GABA(B)) agonist, might improve neurobehavioral function in affected patients. We evaluated whether STX209 improves behavioral symptoms of fragile X syndrome in a randomized, double-blind, placebo-controlled crossover study in 63 subjects (55 male), ages 6 to(More)
BACKGROUND Inhaled glucocorticosteroids are indicated for the treatment of persistent asthma; however, many young children are unable to effectively use currently available inhalers. OBJECTIVE We sought to evaluate the efficacy and safety of 3 different twice daily doses of budesonide inhalation suspension (Pulmicort Respules) in inhaled steroid-dependent(More)
RATIONALE Topical antiinflammatory medications such as inhaled corticosteroids are recommended for therapy of asthma, but no formulation suitable for administration to infants and young children is available in the United States. METHODS This was a 12-week, multicenter, double-blind, randomized, parallel-group study comparing the efficacy and safety of(More)
STX209 (arbaclofen), a selective GABA-B agonist, is hypothesized to modulate the balance of excitatory to inhibitory neurotransmission, and has shown preliminary evidence of benefit in fragile X syndrome. We evaluated its safety, tolerability, and efficacy in non-syndromic autism spectrum disorders, in an 8-week open-label trial enrolling 32 children and(More)
BACKGROUND & AIMS Budesonide is a highly potent topical glucocorticosteroid that is characterized by low systemic availability as a result of high first-pass hepatic metabolism. The aim of this study was to evaluate the efficacy and safety of three doses of an enema preparation of budesonide in patients with active distal ulcerative colitis/proctitis. (More)
BACKGROUND Inhaled glucocorticosteroids (GCS) are the most effective long-term controller medications for the treatment of persistent asthma. Currently, however, available delivery devices limit their use in young children. A nebulized formulation of budesonide has been developed to address the needs of infants and young children. OBJECTIVE To evaluate(More)
Arbaclofen improved multiple abnormal phenotypes in animal models of fragile X syndrome (FXS) and showed promising results in a phase 2 clinical study. The objective of the study is to determine safety and efficacy of arbaclofen for social avoidance in FXS. Two phase 3 placebo-controlled trials were conducted, a flexible dose trial in subjects age 12–50(More)
Autism Spectrum Disorder (ASD) is associated with persistent impairments in adaptive abilities across multiple domains. These social, personal, and communicative impairments become increasingly pronounced with development, and are present regardless of IQ. The Vineland Adaptive Behavior Scales, Second Edition (Vineland-II) is the most commonly used(More)
We conducted a double-blind, placebo-controlled, multicenter trial comparing the efficacy of famotidine 40 mg administered at bedtime (HS), 20 mg given twice daily (BID), and placebo to relieve heartburn and to heal endoscopically documented esophageal erosions or ulcerations. A total of 338 patients were randomized: 135 to receive famotidine 40 mg HS, 137(More)
