Phase 3 randomized, triple-masked trial comparing YCJ-01 (full‑spectrum cannabis extract) with placebo in people with refractory epilepsy caused by Tuberous Sclerosis Complex. The study measures changes in monthly seizure counts and tracks safety over a 6‑month period. Secondary measures include response rates, seizure‑free proportions, and changes in seizure type and severity.
What it is studying. Whether treatment with YCJ-01 (a full‑spectrum cannabis extract) changes seizure frequency, seizure control (severity and types), and safety compared with placebo in people with refractory epilepsy due to TSC.
What the researchers hope to learn. To assess efficacy of YCJ-01 by measuring changes in the number of epileptic seizures and to assess the safety profile. To measure response rates (including ≥50% seizure reduction), proportions achieving 25/50/75/90% reductions, rates of seizure‑freedom, and changes in seizure severity and types.

Study description and what participation involves
The study's detailed description, as published on ClinicalTrials.gov.
Show the detailed description from the registry
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).

AI summaryWhat participation may involve, in plain languageShow ▾Hide ▴
AI-written from the registry record, not the study's own wording. May contain errors or omissions. Check the registry text on this page and the original record ↗ before acting on it.
Participants are randomly assigned (triple‑masked) to receive either the full‑spectrum cannabis extract YCJ‑01 or a matching placebo. They will keep a seizure diary and attend regular study visits with safety checks (vital signs and blood tests) and assessments of seizure number and severity over the trial (primary outcomes measured through 6 months). Participants must report adverse events and follow study instructions; women of child‑bearing potential must use contraception as required. No unusually invasive procedures are listed in the record beyond routine safety monitoring.
How the study is structured. Phase 3 interventional (treatment) trial. Participants are randomly assigned to receive YCJ-01 or matching placebo in a sequential design. The study is triple-masked (participants, care providers, and outcome assessors are blinded). Participants are followed with repeated seizure counts and safety monitoring over the study period (primary outcomes recorded over 6 months). After the randomized, placebo-controlled part, the trial continues with an open-label phase in which all participants receive YCJ-01.
Questions you could ask
These questions are suggestions for a conversation with the study team or your own clinician, not advice.
- Some participants receive a placebo. How is that decided, and what happens for placebo-group participants when the study ends?
- The listed sites are in Spain. Is any of them reachable for me, and does the study help with travel?
- Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai
- refractory
- A condition that has not responded to a treatment. 'Relapsed' means it responded and then came back; 'refractory' means it did not respond in the first place.
- informed consent
- The process of explaining a study, including its risks and what participation involves, so that a person can decide freely whether to take part. Consent is usually documented in writing, and a participant can choose to leave the study later.
- investigational
- A treatment that is being tested and has not been approved for this use. It may be approved for a different condition. Being studied does not mean it works or is available outside the study.
- legal representative
- A person who is legally allowed to make decisions, including consent to research, on behalf of someone who cannot consent for themselves.
- placebo
- A treatment that looks like the study treatment but contains no active ingredient. Some participants receive it instead of the study treatment, usually without knowing which they got.
- Inclusion Criteria
- The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
- Exclusion Criteria
- The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
- baseline
- Measurements taken at the start of the study, before any study treatment, so that later results can be compared with them.
- Adverse Events
- Any unwanted medical problem that happens during a study, whether or not it was caused by the treatment. A 'serious' adverse event is one that meets specific criteria, such as causing death, being life-threatening, requiring or prolonging hospital admission, causing significant disability, or another medically important outcome.
- primary objective
- The main result the study is designed to measure and report on. Other results, called secondary outcomes, are also collected.
- secondary objective
- An additional result the study measures alongside the primary outcome, for example quality of life or a laboratory value.
