Parallel Comparison Analyses Confirm That Insys Therapeutics' Synthetic CBD Is Identical in Chemical Structure to Plant-Derived CBD

PHOENIX, AZ--(Marketwired - Dec 4, 2014) - Independent comparison analyses have found that cannabidiol (CBD) synthetically produced by Insys Therapeutics, Inc. (NASDAQ: INSY) is chemically identical to plant-derived CBD. Analyses were conducted independently by Insys and the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.

The two separately-conducted analyses ascertained that Insys' synthetically produced CBD:

  • Has identical identity and chemical structure to plant-derived CBD;
  • Has identical stereochemistry to plant-derived CBD; both demonstrated the same (-) CBD enantiomer with no (+) enantiomer present, which was confirmed by Chiral Assay;
  • Is more pure, with a 2% higher CBD Assay value than plant-derived CBD;
  • Insys CBD total HPLC purity 99.9% vs. plant-derived CBD at 98.7%; and,
  • Meets all ICH impurity guidelines, with no impurities greater than 0.10%, vs. plant-derived CBD which contained multiple impurities above ICH guidelines.

"The results of NIDA's analyses confirm those conducted in our laboratories, demonstrating that our CBD is identical in chemical structure to plant-derived CBD as determined by multiple methods," said Michael L. Babich, President and Chief Executive Officer of Insys. "We believe our product's purity levels will provide consistent material for our clinical programs, including our program to evaluate CBD in pediatric patients suffering from Dravet Syndrome and Lennox-Gastaut Syndrome. We plan to dose our first human subjects in the first quarter of 2015 in a Phase I setting."

For these independent comparison analyses, both organizations utilized NIDA-supplied natural, plant-derived CBD and synthetically produced CBD supplied by Insys. Insys' synthetic, pharmaceutical CBD is manufactured under cGMP conditions at its FDA-inspected and Drug Enforcement Administration (DEA)-approved facility in Round Rock, Texas, and therefore Insys manufactured CBD has greater batch-to-batch consistency and uniformity. Insys believes that it is the only U.S.-based company with the capacity to produce pharmaceutical cannabinoids in scalable quantities.

NIDA, a component of the National Institutes of Health, U.S. Department of Health and Human Services, supports most of the world's research on the health aspects of drug abuse and addiction. Insys has been approved as a qualified supplier of CBD to NIDA, and NIDA will refer CBD requests (from state agencies, research projects, clinical trials, etc.) directly to Insys.
