New treatment option for Proven Pathogenic or Probably Pathogenic TBR1 Variant
Official title A Study Evaluating 24 Months of Lithium Carbonate Treatment in Patients With TBR1-related Neurocognitive Disorder
ClinicalTrials.gov ID: NCT06776848
What this study is testing
What is Lithium treatment?
Lithium treatment is an investigational medicine, given as an once-daily, being studied as a potential treatment for proven pathogenic or probably pathogenic tbr1 variant.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- TBR1 is a human gene encoding a brain-specific transcription factor, principally expressed in the excitatory neurons of the neocortex. It regulates development of axonal projection and expression of numerous genes involved in autism spectrum disorders (ASD) and intellectual disability (ID).
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
