Key inclusion & exclusion criteria

Inclusion Criteria:

- 0-6 months of age at the time of enrollment (randomization and treatment initiation
must occur before 7 months of age and infants born prematurely must have a corrected
age of at least 39 weeks, calculated by subtracting the number of weeks born before 40
weeks gestation from the actual chronological age, in weeks)

- Has a confirmed diagnosis of TSC based on established clinical or genetic criteria

Exclusion Criteria:

- Prior history of seizures (clinical or electrographic) at the time of enrollment or
identified on baseline EEG

- Has been treated in the past or is currently being treated at the time of enrollment
with conventional anticonvulsant medications (AEDs), systemic (oral) mTOR inhibitors
(such as rapamycin, sirolimus, or everolimus), ketogenic-related special diet, or
another anti-seizure therapeutic agent, device, or procedure

- Has taken any other investigational drug as part of another research study, within 30
days prior to the baseline screening visit

- Has a significant illness or active infection at the time of the baseline screening
visit

- Has a history of significant prematurity, defined as gestational age <30 weeks at the
time of delivery, or other significant medical complications at birth or during the
neonatal period that other than TSC would convey additional risk of seizures or
neurodevelopmental delay (i.e. HIE, severe neonatal infection, major surgery,
prolonged ventilatory or other life-saving supportive care or procedures)

- Abnormal laboratory values at baseline (i.e., renal function, liver function, or bone
marrow production) that are in the opinion of the investigator clinically significant
and may jeopardize the safety of the study subject

- Prior, planned or anticipated neurosurgery within 3 months of the baseline visit

- Has a TSC-associated condition for which mTOR treatment is clinically indicated (i.e.
SEGA or AML)

- Subjects who are, in the opinion of the investigator, unable to comply with the
requirements of the study
