Main objective
Scope: Efficacy, Therapy, Safety
Neuropsychologic outcome at 24 months of age assessed by rater blinded neuropsychologic testing measured by the cognitive scale on the Bayley Scales of Infant and Toddler Development III (BSID-III)
compared with Standard of Care (SOC) alone.
Secondary objectives 12
- Neuropsychologic outcome at 12 months of age assessed by rater blinded neuropsychologic testing using the cognitive scale on the BSID-III in both groups. Cognitive impairment will be defined as BSID-III cognitive scale score <70 similar to the EPISTOP trial.
- Adaptive behaviour assessed by the Vineland Adaptive Behaviour Scales (VABS-3; digital) at the age of 12 months and 24 months.
- Evidence for autism spectrum disorder measured at 12 months and 24 months of age by the Autism Diagnostic Observation Schedule (ADOS-2). Suspicion of autism spectrum disorder will be defined as ADOS >12, similar to the EPISTOP trial.
- Evidence for autism spectrum disorder measured by the Modified Checklist for Autism in Toddlers revised (M-CHAT-R/F).
- TSC-associated Neuropsychiatric Disorders (TAND) severity assessed by the TAND-L Checklist (German version) at 12 and 24 months
- Assessment of seizure frequency and the occurrence/severity of infantile spasms (IS) measured by seizure diaries, care giver questionnaires and electroencephalogram (EEG) recordings
- Reduction of number and size of cardiac rhabdomyoma and arrhythmia (if present).
- Reduction of cerebral tumor number and size on cranial magnetic resonance imaging (cMRI) (if present)
- Adverse events (AE), serious adverse events (SAE) and Adverse Events of Special Interest (AESI), assessed by the Common Terminology Criteria of Adverse Events (CTCAE, Version 5.0, or most recent version).
- Assessment of safety laboratory data and vital signs
- Assessment of EEG recordings for the occurrence of hypsarrhythmia and epileptiform discharges.
- Renal changes in abdominal sonography: Volume and size of angiomyolipomas (if present), kidney size, renal pelvis dilation, echogenicity.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 3
- Definite diagnosis of TSC according to the 2021 Updated International Tuberous Sclerosis Complex Diagnostic Criteria
- <4 months of age at the time of enrolment (randomization and treatment initiation must occur before 4 months of age; 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)
- Signed informed consent from legal guardian(s) prior to any study specific procedure.
Exclusion criteria 7
- Has a TSC-associated condition for which mTOR treatment is clinically indicated, i.e. subependymal giant cell astrocytoma (SEGA).
- Has been treated in the past or is currently being treated at the time of enrolment with systemic mTOR inhibitors (such as rapamycin, sirolimus, or everolimus)
- Contraindication to study medication. Rapamune® oral solution contains soya oil. Patients allergic to peanut or soya must not take this medicine
- Current enrolment, or observation period of competing clinical trials at any time during enrolment in the study.
- 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, apart from TSC, would convey additional risk of seizures or neurodevelopmental delay (i.e. hypoxic ischemic encephalopathy (HIE), severe neonatal infection, major surgery, prolonged ventilatory or other lifesaving supportive care or procedures)
- Abnormal laboratory values at screening (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.
- Parents / caregiver of the child who are, in the opinion of the investigator, unable to comply with the requirements of the study
