Preventing Epilepsy Using Vigabatrin In Infants With Tuberous Sclerosis Complex

Preventing Epilepsy Using Vigabatrin In Infants With Tuberous Sclerosis Complex (PREVeNT Trial) A Randomized, Double-blind, Placebo-controlled Seizure Prevention Clinical Trial for Infants With TSC

• Status: Completed
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 84 (actual)
• Sponsor: Martina Bebin · Academic / Other
• Sex: All
• Age: 1 Day – 6 Months
• Healthy volunteers: Not accepted

Summary

Study design is a Phase IIb prospective multi-center, randomized, placebo-controlled, double-blind clinical trial. The goal will be to enroll 80 infants with Tuberous Sclerosis Complex who are less than 6 months of age prior to the onset of their first seizure

Detailed description

The central hypothesis of this Phase IIb trial is that early identification of electroencephalography (EEG) biomarkers and early treatment versus delayed treatment with vigabatrin in infants with tuberous sclerosis complex (TSC) will have a positive impact on developmental outcomes at 24 months of age. It would also prevent or lower the risk of developing infantile spasms and refractory seizures. This preventative approach would be expected to result in more favorable long-term cognitive, behavioral, developmental and psychiatric outcomes and significantly improve overall quality of life. It is a randomized, double-blind, placebo-controlled clinical trial design. Successful completion of this trial will also advance the field by demonstrating the value of systematic surveillance with EEG in asymptomatic infants with TSC.

Conditions

• Tuberous Sclerosis Complex

Interventions

Type	Name	Description
DRUG	Early Vigabatrin	Subjects randomized to vigabatrin will be treated with vigabatrin 100mg/kg/day until 24 months of age or until they show evidence of clinical seizures or electrographic seizures on video EEG. If electrographic or clinical seizures occur while on study drug, they will transition into the Open label phase of the study and continue to be followed until 36 months of age.
DRUG	Delayed Vigabatrin (Placebo)	Subjects randomized to placebo will be treated with matching placebo at 100mg/kg/day until 24 months of age or until they show evidence of clinical seizures or electrographic seizures on video EEG. If electrographic or clinical seizures occur while on study drug, they will transition into the Open label phase of the study and continue to be followed until 36 months of age.
