Cannabis oil trial aims to tame seizures in rare genetic disorder
NCT ID NCT07403266
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tests a full-spectrum cannabis extract (YCJ-01) in 84 people aged 2 to 65 with tuberous sclerosis complex (TSC) whose seizures have not been controlled by standard treatments. Participants will receive either the cannabis extract or a placebo for two months. The study measures whether the extract reduces monthly seizure counts and monitors for side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- full-spectrum cannabis extract (YCJ-01)
- What this could lead to
- If it works, this could offer a new treatment option to reduce seizures in people with tuberous sclerosis complex who have not responded to other therapies.
- What could go wrong
- This is a Phase 3 trial, but it is still relatively small (84 participants). The cannabis extract may not reduce seizures more than a placebo, and side effects are possible.
