Results from Seizure Study Program
Lexaria Bioscience Corp. (“Lexaria”) has partially completed its study program EPIL-A21-1 which was designed as a three-part series utilizing Sprague Dawley rats; 21 animals in the pilot study; 24 animals in time to peak efficacy study; and 24 animals in the ED50 study (the dose required to achieve seizure inhibition in 50% of the animals tested); to determine whether DehydraTECH-CBD could provide similar seizure inhibiting efficacy, at lower doses than were required with Epidiolex®. In all three experiments, seizure activity was induced by the using an established, vehicle-controlled, acute animal seizure model induced by electrical stimulation (“MES”) and treatment effect was judged by evaluation of acute clinical signs in the animals. Treatment timing relative to seizure induction following the MES model methodology was based upon published literature of the biological activity of the positive control, Epidiolex. Study program EPIL-A21-1 is being performed by a leading, US-based independent laboratory and is fully funded by Lexaria.
The pilot study examined three different doses and revealed that, at the lower doses of 50 mg/kg and 75 mg/kg, DehydraTECH-CBD was more efficacious than Epidiolex in reducing or eliminating seizure activity. Epidiolex was more efficacious than DehydraTECH-CBD in eliminating seizure activity at the highest dose tested in the pilot study of 100 mg/kg. Only DehydraTECH-CBD demonstrated some reduction in seizure activity at the 50 mg/kg dose. At the 75 mg/kg dose DehydraTECH-CBD demonstrated full elimination of seizure activity in 66.6% of the animals compared to 50% of the Epidiolex treated animals. In this regard there was an apparent trend for DehydraTECH-CBD to be more efficacious at lower doses than Epidiolex.
The time to peak efficacy study compared the effectiveness of DehydraTECH-CBD to Epidiolex at various post-dosing time points and showed an apparent trend toward enhanced effectiveness of DehydraTECH-CBD, in this case based on rapidity of action. At the 30-minute timepoint, 50% of the animals dosed with DehydraTECH-CBD showed partial reduction or full elimination of seizure activity whereas 100% of the Epidiolex-dosed animals were exhibiting full seizure activity at 30 minutes. At the 60-minute timepoint 87.5% of the animals dosed with DehydraTECH-CBD showed partial reduction or full elimination of seizure activity compared to 62.5% of the Epidiolex-dosed animals showing partial reduction or full elimination of seizure activity. Epidiolex showed some enhanced seizure reduction capabilities at later time points in the study.
The final ED50 study is currently underway and Lexaria will provide updates regarding this study’s results when they become available.
