Cannabidiol preparations and its uses
Patent 11,207,292
Issued: December 28, 2021
Inventor(s): Guy Geoffrey & Knappertz Volker & Whalley Benjamin & Woolley-Roberts Marie & Brodie James & Lach-Falcone Katarzyna & Sutton Alan & Gray Royston & Rana Rohini Rajyalaxmi
Assignee(s): GW Research LimitedCannabidiol (CBD) is a cannabinoid designated chemically as 2-[(1R,6R)-3-Methyl-6-(1-methylethenyl)-2-cyclohexen-1-yl]-5-pentyl-1,3-benzenediol. Its empirical formula is CHOand its molecular weight is 314.46. CBD is a cannabinoid that naturally occurs in the L. plant. CBD is a white to pale yellow crystalline solid which is insoluble in water and soluble in organic solvents. The present invention encompasses the surprising recognition that certain CBD preparations which are prepared from a botanical origin are more effective in treating diseases or disorders than preparations of CBD which are synthetic or purified to the extent no other impurities in the form of other cannabinoids are present. Prior CBD compositions have been prepared such that no psychoactive components, e.g., tetrahydrocannabinol (THC), remain in the final CBD preparation. Surprisingly, the absence of such minor impurities reduces the efficacy of CBD treatment. Such CBD preparations are characterized by chemical components and/or funtional properties that distinguish them from prior CBD compositions. One or more components of the preparations described herein provide an unexpectedly synergistic effect when utilized in combination.

Glossary
| Term | Definition |
|---|---|
| Drug Patent | A drug patent is assigned by the U.S. Patent and Trademark Office and assigns exclusive legal right to the patent holder to protect the proprietary chemical formulation. The patent assigns exclusive legal right to the inventor or patent holder, and may include entities such as the drug brand name, trademark, product dosage form, ingredient formulation, or manufacturing process A patent usually expires 20 years from the date of filing, but can be variable based on many factors, including development of new formulations of the original chemical, and patent infringement litigation. |
| Drug Exclusivity | Exclusivity is the sole marketing rights granted by the FDA to a manufacturer upon the approval of a drug and may run simultaneously with a patent. Exclusivity periods can run from 180 days to seven years depending upon the circumstance of the exclusivity grant. |
| RLD | A Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart. |
