Aspirin as an add-on Treatment of Refractory Epilepsy in Tuberous Sclerosis Complex

Study Purpose

There had been much evidence in aspirin controlling tumorous conditions conducted by basic researches, especially through mammilian target of rapamycin (mTOR) pathway. The investigator observed efficacy of aspirin in the treatment of tuberous sclerosis complex (TSC) in one child who got Kawasaki disease and in the addition four TSC patients with epilepsy. The investigator intend to evaluate whether aspirin would be an effective add-on treatment in TSC patients with refractory seizures.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. 6-30 years old TSC patients (by Gomez criteria) 2. more than 8 seizures occurred in the 4-week baseline time,with no continued seizure-free time of more than 10 days a month 3. more than two antiepileptic drugs (AED) had been administered but fail to control the situation; maintaining with 1 or more than 1 AEDS for over 2 months and intending to continue with the drugs 4. patients who had been treated with rapamycin should have been stopped for more than 3 months 5. vagus nerve stimulation (VNS) is allowed as a previous or current therapy and would maintain until the end of the trial

Exclusion Criteria:

1. Subependymal Giant Cell Astrocytoma and requires immediate surgery; 2. a history of intracranial surgery within 6 months; 3. epilepsy caused by improper use of drugs; 4. patients treated with aspirin had severe or intolerant side effects, including gastrointestinal ulcer, bleeding, aspirin allergy, and other conditions; 5. psychogenic seizures; 6. severe renal dysfunction and infection 7. pregnant women and lactating women 8. not regular follow-up 9. other: because when children and adolescents suffering from influenza or chickenpox, using aspirin may cause a rare life-threatening Reye syndrome (characterized with persistent vomiting), should temporary withdrawal, medication needs to consult a physician before using again.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03356769
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

There is no optional treatment for patients with tuberous sclerosis complex (TSC) and refractory epilepsy.The investigator observed efficacy of aspirin in the treatment of in one child who got Kawasaki disease. Subsequent adjunctive aspirin therapy in four patients yielded a reducted frequency of seizure for 51.2-89.7%. The investigator intend to evaluate whether aspirin would be an effective add-on treatment in TSC patients with refractory seizures. Refractory epilepsy was defined as more than 8 times of epileptic events in 4 weeks at baseline, and had been given more than two antiepileptic drugs maintaining for more than 3 months.TSC patients aged 6-30 years' old would be recruited with refractory seizures and randomly assigned to two groups, aspirin and antiepileptic drugs(AEDS) group and placebo-AEDS group after written informed consent be obtained. Patients and their guardians would be instructed to record their own seizure diary on the epileptic events and report monthly.The primary outcome would be reduction of seizure frequency (measured by average seizure frequency and response rate). The secondary outcome would include seizure-free days, seizure-free rates, changes in EEG, changes of facial angiofibromas, and exposure-response relationship analysis.The study is designed as a placebo-controlled, randomized, blinded evaluation trial.
