1.87/1000 patients. in hospital admission.
At 2003-40000patients. (USA) with primary Hepatic Encephalopathy -Cost:932M.US$
To date, there is no effective treatment of liver diseases with the related
· Hepatic-Encephalopathy occurs in:
30-45% of patients with cirrhosis.
10-50% of patients with transjugular intrahepatic portosystemic shunt.
· Minimal symptoms of Hepatic-Encephalopathy occur in 20-60% of patients with liver diseases.
· 30% of patients dying of end stage liver diseases experience significant Hepatic-Encephalopathy.
· NAFLD is estimated to occur in one-third of the general population in the US.
· Strategies to lower ammonia production/absorption.
· Medications to counteract ammonia effect on brain cell function.
· Devices to compensate liver dysfunction.
· Liver transplantation.
· Treatment of liver disease(Cirrhosis/steatosis) and hepatic encephalopathy with cannabidiol or capsaicin and/or cannabinoids (THC/HU308) / endocannabinoids ( 2-AG).
· Method of administration: oral, parenteral, sublingual or intranasal is yet to be determined.
· Has been shown to improve both liver and brain function in a mouse models of hepatic encephalopathy(Both acute and chronic models).
· No side effects were noticed (FHF acute model)(BDL chronic model).
· No toxicity in chronic administration.
We have shown in mouse experimental models that cannabinoids/endocannabinoids and/or capsaicin or cannabidiol, improve both liver and brain functions. We suggest a treatment modality based on the following mechanism/s: blocking the CB1 receptor and stimulating the CB2 receptor by 2AG or HU308 or THC (for hepatic encephalopathy) and/or the TRPV1 receptors by capsaicin and/or the 5HTIA receptors by Cannabidiol . Thus, inducing therapeutic effect which is mediated through effects in the liver and brain.
The Business Opportunity
We are presently seeking to raise 0.5M.US$ to complete efficacy and safety studies in animal models and to Progress to preliminary human studies (safety and proof of concept) once pre-clinical safety has been determined .
