Adjunctive Ganaxolone Treatment (Part A) in TSC Followed by Long-term Treatment (Part B) — TSC  

Tuberous Sclerosis Clinical Trial

Official title: A Phase 2 Open-label 12-Week Trial of Adjunctive Ganaxolone Treatment (Part A) in Tuberous Sclerosis Complex-related Epilepsy Followed by Long-term Treatment (Part B)

Status Completed

Clinical Trial Summary

To assess preliminary safety and efficacy of ganaxolone as adjunctive therapy for the treatment of primary seizure types in patients with genetically- or clinically-confirmed TSC-related epilepsy through the end of the 12 week treatment period.

Clinical Trial Description

This is an OL proof of concept study of adjunctive GNX treatment in patients with a confirmed clinical diagnosis of TSC and/or a mutation in either the TSC1 or TSC2 gene. The trial consists of two parts: Part A consists of a 4-week baseline period followed by a 12-week treatment period (4-week titration and 8-week maintenance). For patients not continuing in the 24-week OLE period (Part B), a 2-week taper period followed by a 2-week safety period would follow. The main difference between Part A and Part B is the length of treatment, less frequent assessments, and the ability to alter drug doses (both GNX and other antiepileptic drug [AED] treatments which includes initiating and stopping other medications) based on investigator evaluation of the patient's clinical course during Part B. Patients with a seizure frequency reduction during the 12-week treatment period in Part A compared to baseline may continue into Part B ("OLE eligible"), to assess long-term safety, efficacy and tolerability in patients with TSC-related Epilepsy. ;
