Cardiol Therapeutics' Pharmaceutical Partner Noramco Presents at U.S. FDA Public Hearing on CBD

Addresses Need for Improved Standards and Regulations

Oakville, Ontario--(Newsfile Corp. - June 3, 2019) - Cardiol Therapeutics Inc. (TSX: CRDL) (OTCQX: CRTPF) ("Cardiol" or the "Company"), a leader in the research and commercial development of pharmaceutical cannabidiol (CBD) and targeted therapies for inflammatory diseases, announces that Noramco, Inc. (Noramco) of Wilmington, Delaware, Cardiol's pharmaceutical partner and manufacturer of its pure pharmaceutical CBD, was selected to present at the Food and Drug Administration's (FDA) Scientific Data and Information about Products Containing Cannabis or Cannabis-Derived Compounds, Part 15 Public Hearing, that took place on Friday, May 31, 2019, in Silver Spring, Maryland.

The goal of the hearing was to obtain additional scientific data and other information related to cannabis and cannabis-derived compounds to inform the FDA about these products. The FDA invited important stakeholders, including patients, researchers, manufacturers, retailers, and public health and government bodies, all of whom contributed data and experience.

Noramco has more than 40 years' experience and expertise in the manufacture and supply of controlled drug substance active pharmaceutical ingredients (APIs), including cannabinoids. Their APIs are sold in over 30 countries and they have 24 active US Drug Master Files (DMF), including a DMF for pharmaceutical CBD. Noramco is fully cGMP-compliant (FDA inspected and regulated) and has demonstrated a total capacity of >750,000 kg annually in state-of-the-art facilities.

Key messages and recommendations presented at the Hearing by Bill Grubb, Chief Innovation Officer and Executive VP of Business Development of Noramco, included the following:

There is a Need for Federal Oversight of Manufacturing and Testing of CBD Products

Noramco's own analysis using certified analytical reference standards and scientifically-sound analytical methods confirmed impurities of up to 4.39% in several available botanical CBD products - over 1,000 times higher than Noramco's pure pharmaceutical CBD.





Numerous other examples of mislabeled and impure CBD products in the marketplace have been cited, including a Journal of the American Medical Association (JAMA) study finding 69% of 84 cannabidiol botanical extract products were mislabeled, triggering the FDA to send warning letters to 14 businesses. The average amount of THC in the products was greater than 4000 parts per million (PPM), enough to produce intoxication or impairment.

cGMP Production is Essential to Provide Safe CBD

Noramco follows formal FDA-administered cGMP procedures to ensure the highest level of quality, purity, consistency, and





Noramco has established multi-ton cGMP production capability for pure pharmaceutical CBD in excess of 180,000 Kg per annum.





Noramco utilizes organic chemical synthesis to produce CBD. This process eliminates the risk of contamination by pesticide residues or heavy metals from soil and therefore there are no environmental influences on quality.

Tight Control Limits for Impurities and Assess Stability of Active Ingredients in all CBD Products

The FDA should adopt International Council for Harmonisation (ICH) guidelines for producers of CBD, from any source, for control of impurities, setting specifications, and for monitoring product stability.





Product stability and label accuracy over time can only be assured if CBD is produced and monitored according to long-established regulations, and all commercially available CBD products should have expiry dates.

Limit THC Impurity Levels to ≤1000 PPM in CBD medicines

CBD producers should control THC to ≤ 1000 PPM. Noramco's pharmaceutical CBD has THC levels orders of magnitude lower, measuring less than <10 PPM; meeting Health Canada's strict standards for products that do not require a warning label concerning THC content.

"Noramco's commitment to making the purest, safest, and most consistent CBD in the world, at multi-ton scale, underscores Cardiol's rationale for selecting their world-class pharmaceutical production capabilities for our proprietary CardiolRx pure pharmaceutical CBD formulations," said David Elsley, President & CEO of Cardiol Therapeutics. "In collaboration with Noramco and Dalton Pharma, our exclusive global drug formulation partner, Cardiol is now positioned to commercialize pure pharmaceutical CBD products designed to set the highest industry standards for product purity, safety, and consistency for consumers, patients and healthcare providers around the world."

"Noramco is pleased to be partnering with Cardiol Therapeutics to provide consumers access to the purest and safest CBD. Noramco's pharmaceutical CBD is produced in accordance with cGMP and is tested to assure identity, purity, quality, and strength. Noramco has clearly demonstrated that multi-ton cGMP-compliant production of CBD is now viable," stated Mr. Grubb of Noramco.
