The current situation of epilepsy is a very frequent problem with onset in the first years of life in patients with tuberous sclerosis complex (TSC). There are many current therapeutic options; however, 63.3% of patients have uncontrolled epilepsy and most of them experience daily seizures. Poor seizure control is correlated with intellectual disability and autism spectrum disorder. Given the lack of effective treatments for the management of refractory epilepsy, a prospective, experimental clinical trial has been designed. Although there are additional treatment options such as vagus nerve stimulation and the ketogenic diet (apart from antiepileptic drugs), they do not control epilepsy.
Comparison of the number of monthly seizures since the initiation of the treatment with YCJ-01 with respect to the baseline period: in patients assigned to receive YCJ-01, change in the number of monthly seizures in the second month of treatment with respect to the baseline period; and in patient assigned to receive a placebo, changes in the number of monthly seizures in the second month of treatment with YCJ-01 with respect to the baseline period.
Occurrence of Adverse Events (AE), Severe AE (SAE), AE resulting in study treatment withdrawal, AE of special interest (AESI), and changes in vital signs and laboratory values during the clinical trial. (Variable associated to the primary objective 2). To assess the response rate to YCJ-01/placebo: patients who achieve a decrease in at least a 50 % of the number of epileptic seizures compared to the baseline period (from visit P0 to P1) will be considered responders.

(Variable associated with the secondary objective 3).

(Variable associated with the secondary objective 3).
Effect on control of epileptic seizures (variable associated to the secondary objective 4): Changes in severity and in types of epileptic seizures will be assessed after the initiation of the treatment (from visit P1 to P2, from visit P2 to P3, from visit P3 to P4, from visit P4 to P5, from visit P5 to P6, from visit P6 to P7) with respect to the baseline period (form visit P0 to P1).Comparison of the number of monthly epileptic seizures between the two treatment groups and the baseline period: change in number of monthly seizures of patients assigned to receive the investigational medicinal product during the second month of treatment (from visit P2 to P3) with respect of the baseline period (from visit P0 to P1), in comparison to the second month of treatment (from visit P2 to P3) to the group receiving placebo with respect to the baseline period (from visit P0 to P1).
