NEW YORK CITY – Data from an initial proof-of-concept clinical pharmacokinetic study demonstrate that Receptor Life Sciences' research team has found a way to address the bioavailability and variability challenges that have stymied cannabinoid pharmaceutical researchers.

The company is pursuing pathways with the U.S. Food and Drug Administration to bring its investigational therapies to market, using drug delivery platforms already validated by their use in marketed prescription drugs.

"The effectiveness of cannabinoid medicines is negatively impacted by poor bioavailability, highly variable absorption, and erratic time to onset," said Dr. Andrea Leone-Bay, PhD, Chief Scientific Officer and a founder of Receptor Life Sciences. "We are developing solid dosage therapeutics, both oral and inhaled, designed to address these cannabinoid delivery challenges."

Dr. Leone-Bay will present data on the Company's initial oral and inhaled cannabinoidderived product candidates at the 3rd International Cannabinoid Derived Pharmaceuticals Summit.

"Currently available cannabinoid dosage forms attempt to compensate for some of these deficiencies with high doses," said Dr. Leone-Bay. "Unfortunately, higher doses bring the potential to produce undesirable side effects."

Dr. Leone-Bay is an internationally recognized authority on inhaled dry powder and oral drug delivery technologies. She brings unparalleled pharmaceutical development and formulation expertise with 48 publications in peer-reviewed journals and over 100 issued U.S. patents. She previously served as Vice President, Pharmaceutical R&D, Mannkind Corporation.

Researchers believe that cannabinoid medicine has incredible potential that has only recently become a focus of rigorous scientific investigation.

SEATTLE - Receptor Life Sciences ("RLS"), a leading biopharmaceutical company developing FDA regulated oral and inhaled cannabinoid medicines, today announced that the United States Patent and Trademark Office has issued the Company a Patent for compositions comprising cannabinoids and the company's oral absorption enhancing excipients: U.S. Patent No. 10,588,974.

Receptor's excipients increase oral cannabinoid bioavailability, reduce time to onset and can be formulated as either liquid or solid dosage forms. These products are specifically designed to overcome the challenges of poor, highly variable absorption and long time to onset characteristic of currently available oral cannabinoid medicines.

"This patent provides strong patent coverage for RLS' oral delivery technology platform," said Greg Wesner, Founder, CEO, and General Counsel, Receptor Life Sciences. "The patent provides a broad and versatile foundation for the development of a disruptive product line in oral cannabinoid medicines."

"The simplicity and versatility of RLS oral delivery system allows clear differentiation from the numerous traditional approaches prevalent in the industry; and is based on an excipient granted FDA-approval in other products," added Andrea Leone-Bay Founder and Chief Scientific Officer, Receptor Life Sciences.

Dr. Leone-Bay is an internationally recognized authority on inhaled dry powder and oral drug delivery technologies. The new patent is her 111th.
