This is a Phase 3, global, double-blind, randomized, placebo-controlled study of adjunctive GNX treatment in children and adults with TSC-related epilepsy. The study consists of a 4-week prospective Baseline phase, defined as the first 28 days following screening, followed by a double-blind phase consisting of a 4-week titration period (Day 1 to Day 28) and a 12-week maintenance period (Day 29 to Week 16).

Adjunctive GNX Treatment Compared With Placebo in Children and Adults With TSC-related Epilepsy

A Phase 3, Double-blind, Randomized, Placebo-controlled Trial of Adjunctive Ganaxolone (GNX) Treatment in Children and Adults With Tuberous Sclerosis Complex (TSC)-Related Epilepsy (TrustTSC)

Seizure frequency will be calculated as the total number of seizures divided by the number of days with seizure data, multiplied by 28.

Treatment responders are defined as those participants with ≥ 50% reduction from Baseline in seizure frequency

The CGI-I is a 7-point Likert scale that the parent(s)/caregiver(s)/legally authorized representative (LAR)(s) and clinician uses to rate the change in overall seizure control, behavior, safety, and tolerability after initiation of the Investigational product (IP) relative to Baseline (prior to treatment with the IP). It was rated as: 1- "very much improved", 2- "much improved', 3- "minimally improved", 4- "no change", 5- "minimally worse", 6- "much worse", and 7- "very much worse". Higher scores indicated worse condition.

The ADAMS is a rating scale designed to screen for anxiety and depression in individuals with intellectual disability. The 28-question scale is filled out by the parent(s)/caregiver(s)/LAR(s) and is based on the participant's behavior. Each question will be rated on 4-point Likert scale as follows: 0- "behavior has not occurred or is not a problem"; 1- "behavior occurs occasionally or is a mild problem"; 2- "behavior occurs quite often or is a moderate problem"; and 3- "behavior occurs a lot or is a severe problem". Higher scores indicated worse condition.

The SF-36 is a multi-purpose survey designed to capture participant or parent(s)/caregiver(s)/LAR(s) perceptions of own health and well-being. The SF-36 has 36 items grouped in 8 dimensions: physical functioning, physical and emotional limitations, social functioning, bodily pain, general, and mental health, which are the weighted sums of the questions in each section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. Higher scores represent better health-related quality-of-life.

Peds-QL-FIM is designed to measure the impact of pediatric chronic health conditions on parents and the family. It composes of 6 scales measuring parent self-reported functioning: 1) Physical functioning (6 items), 2) Emotional functioning (5 items), 3) Social functioning (4 items), 4) Cognitive functioning (5 items), 5) Communication (3 items), 6) Worry (5 items), and in addition two scales measuring parent-reported family functioning: 7) Daily activities (3 items) and 8) Family relationships (5 items). Each of the items have five Likert response options: 0 = never a problem, 1 = almost never, 2 = sometimes, 3 = often, 4= almost always. Items are reverse-scored and linearly transformed to a 0-100 scale (0 = 100, 1 = 75, 2 = 50, 3 = 25, 4 = 0); higher scores indicate better functioning (less negative impact).

The ELDQOL is a parent/caregiver/LAR-reported measure that examines seizure severity, seizure related injury, anti-seizure medication (ASM) side effects, behavior, mood, physical status, cognitive and social functioning, communication, overall health and quality of life, and family concerns. There are a total of 70 items, some of which are responded as 1=yes/2=no, some of which range 1-4 and others 1-5. For those items, higher is more severe. For mood-related items, however, the scoring is always/often/sometimes/never which are coded as 1-4 but may be good or bad, depending on the mood. Finally: there are qualitative questions with open-ended answers related to "were any questions difficult to answer" and "are there any other comments you would like to make". Each of the 70 items is characterized as its own measurement, and they are not aggregated or tabulated into an overall score.

The CGI-CSID is a 7-point Likert scale in which the parent(s)/caregiver(s)/LAR(s) assesses change in seizure intensity and/or duration after initiation of investigational product relative to Baseline (prior to treatment with investigational product). The scale ranges from 1- very much improved, 2- much improved, 3- minimally improved, 4- no change, 5- minimally worse, 6- much worse, and 7- very much worse. Higher scores indicate worse condition

ganaxolone suspension (50 mg/ml) TID for 12 weeks with 24 week extension

titration followed by maintenance and extension period

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.

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.

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

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)

Primary seizures include atonic/drop, bilateral clonic, bilateral tonic, focal motor without impairment of consciousness or awareness, focal (motor or non-motor) with impairment of consciousness or awareness, focal to bilateral tonic-clonic, generalized tonic-clonic. Baseline 28-day seizure frequency was calculated as the total number of primary seizures in the Baseline period divided by the number of days with non-missing seizure data in the Baseline period, multiplied by 28. The Baseline Visit was defined as Week 0. Percent change from Baseline in 28-day seizure frequent was calculated as the difference in post-Baseline 28-day seizure frequency and Baseline 28-day seizure frequency, divided by Baseline 28-day seizure frequency, multiplied by 100.

Primary seizures include atonic/drop, bilateral clonic, bilateral tonic, focal motor without impairment of consciousness or awareness, focal (motor or non-motor) with impairment of consciousness or awareness, focal to bilateral tonic-clonic, generalized tonic-clonic. Percentage of participants reporting \>=50 percent reduction in seizure frequency has been presented.

Safety population comprised of all participants who received at least one dose of Ganaxolone.

Participants \>28 kilograms (kg) were administered with Ganaxolone 1800 milligrams per day (mg/day). Following the Treatment period, participants with a seizure reduction of \>=35 percent compared to the Baseline period and who did not have any other contraindications continued to be treated with Ganaxolone in the Open label period.
