Article Synopsis
- * Trofinetide is a medication developed specifically for RTT, recently approved by the FDA for patients aged 2 years and older.
- * The successful development of trofinetide highlights the importance of collaboration between research institutions, pharmaceutical companies, and patient advocacy groups in creating effective treatments for rare diseases.
Article Synopsis
- - Rett syndrome (RTT) is a serious neurodevelopmental disorder without any approved treatments, but a phase 2 trial showed promising results for trofinetide, a drug that improved symptoms in females aged 5-15 compared to a placebo.
- - A new phase 3 trial, called LAVENDER, will evaluate the safety and efficacy of trofinetide in 187 girls and women aged 5-20 using specific clinical scales to assess various aspects of the disorder.
- - The research is designed to track changes in core RTT symptoms and could potentially provide the first strong evidence of a medication’s effectiveness for RTT, marking a significant step forward in treatment options.
Background: We analyze the safety and tolerability of trofinetide and provide a preliminary evaluation of its efficacy in adolescent and adult males with fragile X syndrome.
Methods: This study was an exploratory, phase 2, multicenter, double-blind, placebo-controlled, parallel group study of the safety and tolerability of orally administered trofinetide in 72 adolescent and adult males with fragile X syndrome. Subjects were randomly assigned in a 1:1:1 ratio to 35 or 70 mg/kg twice daily trofinetide or placebo for 28 days.
Objective: To determine safety, tolerability, and pharmacokinetics of trofinetide and evaluate its efficacy in female children/adolescents with Rett syndrome (RTT), a debilitating neurodevelopmental condition for which no pharmacotherapies directed at core features are available.
Methods: This was a phase 2, multicenter, double-blind, placebo-controlled, parallel-group study, in which safety/tolerability, pharmacokinetics, and clinical response to trofinetide were characterized in 82 children/adolescents with RTT, aged 5 to 15 years. Sixty-two participants were randomized 1:1:1:1 to receive placebo twice a day (bid) for 14 days, followed by placebo, 50, 100, or 200 mg/kg bid of trofinetide for 42 days.
Background: This study aimed to determine the safety and tolerability of trofinetide and to evaluate efficacy measures in adolescent and adult females with Rett syndrome, a serious and debilitating neurodevelopmental condition for which no therapies are available for its core features.
Methods: This was an exploratory, phase 2, multicenter, double-blind, placebo-controlled, dose-escalation study of the safety and tolerability of trofinetide in 56 adolescent and adult females with Rett syndrome. Subjects were randomly assigned in a 2:1 ratio to 35 mg/kg twice daily of trofinetide or placebo for 14 days; 35 mg/kg twice daily or placebo for 28 days; or 70 mg/kg twice daily or placebo for 28 days.
Rett syndrome (RTT) requires total caregiver attention and leads to potential difficulties throughout life. The Caregiver Burden Inventory, designed for Alzheimer disease, was modified to a RTT Caregiver Inventory Assessment (RTT CIA). Reliability and face, construct, and concurrent validity were assessed in caregivers of individuals with RTT.

Although the clinical consequences of Rett syndrome are profound and lifelong, currently no approved drug treatments are available specifically targeted to Rett symptoms. High quality outcome measures, specific to the core symptoms of a disorder are a critical component of well-designed clinical trials for individuals with neurodevelopmental disorders.

This is due, in part, to incomplete consensus on the manifestations of anxiety in this population. Autism Speaks assembled a panel of experts to conduct a systematic review of available measures for anxiety in youth with ASD.

ASD is a heterogeneous group of disorders, often accompanied by associated medical issues. Thus, the development of effective treatments is a complex task requiring consideration of diverse etiologic and phenotypic characteristics.
