Jazz Pharmaceuticals is running a phase 1b study to test its cannabidiol oral solution in people with focal-onset seizures. The goal is to see if the drug, already approved for other hard-to-treat seizure disorders, can safely reduce seizure burden in patients aged 12 to 75, which could expand its use and support longer-term revenue growth.
The treatment is an oral cannabidiol solution known as CBD-OS, also called GWP42003-P or JZP926. It is designed to be added to current seizure medicines to improve seizure control without adding major side effects or complex monitoring.
The trial is interventional, with all participants placed into a single treatment group that receives CBD-OS. There is no placebo or blinding, so doctors and patients know they are getting the study drug, and the main goal is to assess treatment benefit and safety in real-world style use.
The study is listed as recruiting, which signals active enrollment and operational momentum. It was most recently updated on June 1, 2026, giving investors comfort that timelines and site activity remain current despite no posted results yet.
Positive data here could strengthen Jazz’s epilepsy franchise and support a broader label, which may lift revenue expectations and support JAZZ’s valuation multiple. Investors should also watch peers in the epilepsy space, as any shift toward cannabidiol-based options could pressure older therapies while creating a niche growth segment.
The study remains active and updated, and investors can track further protocol and status changes on the ClinicalTrials portal.
