A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Is within the required age range at the time of signing (or at the time of the participant’s parent(s)/LAR signing) the informed consent or providing assent (as applicable): • Participants based in the US: 1 to 65 years of age, inclusive. • Participants based outside the US: 2 to 65 years of age, inclusive.
- Participant’s parent(s)/ or LAR is willing to allow the responsible authorities to be notified of the participant’s involvement in the study, if mandated by local law.
- Participant’s parent(s)/LAR is willing to allow his or her primary care practitioner (if they have one) and consultant (if they have one) to be notified of participation in the study, if the primary care practitioner/consultant is different to the investigator.
- Participant (including adults lacking capacity) has a dedicated caregiver to participate in the study.
- Has a confirmed clinical diagnosis of TSC with a history of seizures in accordance with the 2012 International Tuberous Sclerosis Complex Consensus Conference criteria.
- Has behaviors (eg, aggression, impulsivity, temper tantrum, self-injury, hyperactivity, extreme shyness, mood swings, poor eye contact, repetitive behaviors, restlessness, difficulty getting along with peers, rigid/inflexible to procedure and/or change) that are considered moderate or severe per the CareGI-S at Screening. • At Baseline, participants must have a most problematic behavior score of ≥ 6 to remain eligible.
You likely can't join if
- Has a clinically significant unstable medical condition other than epilepsy.
- Has laboratory values at the Baseline Visit that are abnormal and of clinical significance in the investigator’s opinion.
- Participant has significantly impaired hepatic function at the Baseline Visit, defined as any of the following: a. Serum ALT or AST > 5 × ULN b. Serum ALT or AST > 3 × ULN and TBL > 2 × ULN or INR > 1.5 c. Serum ALT or AST > 3 × ULN with the presence of fatigue, nausea, vomiting, right upper quadrant pain or tenderness, jaundice, fever, rash, and/or eosinophilia (> 5%) Note: This criterion can only be confirmed once the laboratory results are available; participants enrolled into the study who are later found to meet this criterion must be withdrawn from the study.
- Has any history of suicidal behavior or any suicidal ideation of type 4 or 5 as evaluated with C-SSRS or Children’s C-SSRS at the Screening Visit (for participants ≥ 4 years of age).
- Has any known or suspected hypersensitivity to cannabinoids or any of the excipients of CBD-OS.
- Has a known or suspected history of alcohol or substance abuse.

- Is naïve to CBD-OS treatment or has been off CBD-OS treatment for at least 3 months prior to Screening.
- Is willing to maintain any factors expected to affect seizures stable (eg, alcohol consumption, smoking, concomitant medication usage).
- Is male or female a. Male participants: • Male participants are eligible to participate if they agree to the following during the intervention period and for at least 2 weeks, corresponding to the time needed to eliminate the study intervention (eg, 5 terminal half-lives) after the last dose of study intervention: − Refrain from donating fresh unwashed semen. PLUS − Use a male condom in addition to a second method of acceptable contraception used by their female partners when having sexual intercourse with a WOCBP who is not currently pregnant. b. Female participants: • A female participant is eligible to participate if she is not pregnant or breastfeeding and one of the following conditions applies: − Is a woman of nonchildbearing potential. OR − Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of < 1% per year), preferably with low user dependency, as described in (Appendix 4 Contraceptive and Barrier Guidance), during the study intervention period and for at least 3 months after the last dose of study intervention. The investigator should evaluate the potential for contraceptive method failure (eg, noncompliance, recently initiated) in relationship to the first dose of study intervention.
- Participant or the participant’s parent(s)/LAR is capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol. • In cases where the participant’s parent(s)/LAR representative signs the ICF and the participant possesses adequate understanding, assent should also be taken according to local regulations.
