Current Environment:

Summary

This phase I/II clinical trial is an open-label clinical trial design to verify safety and dosing for TAVT-18 (sirolimus) powder for oral solution in TSC infants (N=5).

Conditions

Tuberous Sclerosis Complex, Epilepsy

Recruitment Status

Active, not recruiting

Detailed Description

Tuberous Sclerosis Complex (TSC) is caused by genetic mutation in TSC1 or TSC2, resulting in dysregulation of the mechanistic target of rapamycin (mTOR) signaling pathway. Age at time of seizure onset in TSC infants has been linked to long-term neurodevelopmental outcome in this high-risk population. TAVT-18 is a novel formulation of sirolimus, an mTOR inhibitor. This study evaluates TAVT-18 as a targeted, disease-modifying drug therapy for preventing or delaying seizure onset in TSC using a rational, mechanism-based therapeutic approach.

Eligibility 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
