About this study
- To assess treatment efficacy with YCJ-01 by changes in the number of epileptic seizures in patients with refractory epilepsy secondary to Tuberous Sclerosis Complex. 2. To assess the safety of the treatment with YCJ-01 in patients with refractory epilepsy secondary to Tuberous Sclerosis Complex.
Read the detailed description
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.
To assess the proportion of subjects in treatment with YCJ- 01/placebo who achieve a 25%, 50%, 75%, or 90% reduction compared to the baseline period (from visit P0 to P1) in the number of epileptic seizures To assess the proportion of patients in treatment with YCJ-01/placebo free of seizures since the initiation of the assigned treatment.
To assess the effect of YCJ-01 on control of epileptic seizures (changes in seizure severity and types) before and after the initiation of the treatment.
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).

(Variable associated with primary objective 1).
Response rate to YCJ-01: patients who achieve a decrease of at least a 50 % of the number of epileptic seizures with respect to the baseline period (from visit P0 to P1) in visits P3, P4, P6, and P7 will be considered responders. (Variable associated to the secondary objective 1).

Proportion of patients in treatment with YCJ-01 free of epileptic seizures: defined as those participants with no seizure of any type from the initiation of the treatment with YCJ-01 till visit P7, or a period of time that doubles the baseline maximum interval between seizures (International League Against Epilepsy, ILAE).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing YCJ-01 Full Spectrum cannbis Extract in people with Tuberous Sclerosis Complex (TSC), run by Oils4Cure at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 11 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
