Study Summary

The goal of this clinical trial is to learn if an antisense oligonucleotide (TS1-ASO) can safely treat and potentially prevent neuropsychiatric and neurodevelopmental symptoms in pediatric participants (age \>2 months) with Timothy Syndrome Type 1 (TS1). The main questions it aims to answer are: 1. Is TS1-ASO safe and well tolerated when administered intrathecally in children with TS1? 2. What are the pharmacokinetics and preliminary efficacy of TS1-ASO on neurodevelopmental and neurologic outcomes? This is a single-arm study (no comparison group). Participants will: 1. Receive intrathecal injections of TS1-ASO via lumbar puncture using a stepwise dose-escalation approach 2. Undergo safety monitoring including neurologic exams, cardiac monitoring, laboratory testing, and adverse event assessments 3. Provide cerebrospinal fluid (CSF) and blood samples for pharmacokinetic and biomarker analyses 4. Complete neurodevelopmental, behavioral, and functional assessments (e.g., adaptive behavior, motor function, communication, seizure tracking) over time

Primary Outcome

Safety and tolerability of TS1-ASO will be evaluated by systematic collection and analysis of AEs and SAEs following intrathecal administration. Events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 and assessed for severity, seriousness, and relationship to study drug and procedure. Safety assessments include continuous cardiac monitoring (telemetry), serial electrocardiograms, neurologic examinations, and routine la
