“Several works have reported on the antiepileptic impact of cannabis-based preparations in patients with treatment-resistant epilepsy (TRE). However, current formulations suffer from low bioavailability and side effects. PTL-101, an oral formulation containing highly purified cannabidiol (CBD) embedded in seamless gelatin matrix beadlets was designed to enhance bioavailability and maintain a constant gastrointestinal transit time.
Sixteen patients (age: 9.1±3.4) enrolled in the study; 11 completed the full treatment program. The average maintenance dose was 13.6±4.2mg/kg. Patient adherence to treatment regimens was 96.3±9.9%. By the end of the treatment period, 81.9% and 73.4±24.6% (p<0.05) reductions from baseline median seizure count and monthly seizure frequency, respectively, were recorded. Responders’ rate was 56%; two patients became fully seizure-free. By study end, 8 (73%) caregivers reported an improved/very much improved condition, and 9 (82%) reported reduced/very much reduced seizure severity. Most commonly reported treatment-related adverse effects were sleep disturbance/insomnia, (4 (25.0%) patients), followed by somnolence, increased seizure frequency, and restlessness (3 patients each (18.8%)). None were serious or severe, and all resolved.
PTL-101 was safe and tolerable for use and demonstrated a potent seizure-reducing effect among pediatric patients with TRE.”
