 Rapid Therapeutic Prepares to file Investigational New Drug Application for its CBD Metered Dose Inhaler with FDA
 DALLAS, June 2, 2021 (GLOBE NEWSWIRE) -- Rapid Therapeutic Science Laboratories, Inc. (OTC Pink: RTSL) an SEC fully-reporting, growth-oriented aerosol manufacturing company focused on delivery of non-psychoactive cannabinoid compounds, announced today it has executed two (2) contracts to conduct Phase 1 human clinical trials of its flagship metered dose inhaler (MDI) containing Cannabidiol (CBD).  RTSL entered into these two contracts in preparation for filing an Investigational New Drug Application (IND) with the U.S. Food and Drug Administration (FDA). Filing is anticipated in the next 30 days. An IND is a request for the FDA's authorization to administer an investigational drug to humans and is the first step towards designing and conducting clinical trials in the U.S.
 RTSL engaged Dr. Charles Powell, MD who is the Chief Medical Officer (CMO) and founder of a primary care group in North Texas with over 90,000 patients from which volunteers will be solicited for the planned studies. Dr. Powell is responsible for oversight of the studies on behalf of RTSL. Dr. Powell in conjunction with Dr. Haresh Boghara, MD of Epic Medical Research, who has been engaged as RTSL’s primary medical investigator, will launch five clinical studies to assess RTSL’s MDI containing CBD for dosage, efficacy and safety. The planned studies will initially focus on therapeutic benefits of CBD relating to depression, anxiety, insomnia, ADHD and arthritis/chronic pain. Of importance, the studies will measure blood serum levels (pharmacokinetics) to support clinical observations. RTSL will need to file and obtain approval of the IND by the FDA to begin the planned studies.
 Dr. Powell stated, “Based upon my observation from our clinical experience with this product, we think these studies will translate into concrete data that will ultimately result in Phase 2 and 3 studies which will hopefully lead to a fully approved FDA product.”
 RTSL previously announced it was in discussions with Dr. Powell and Accent Clinical Research Professionals, LLC for eight clinical studies. These discussions fell through when the previously proposed lead investigator could not participate due to undisclosed personal reasons not having to do with the proposed testing. 
 RTSL’s CEO, Donal R. Schmidt, Jr. stated, “We made the decision to file an IND based upon a number of things. Most importantly, we believe we are the first company to develop and manufacture an MDI containing pure pharmaceutical grade 
 
 
 CBD isolate that has a good chance of ultimately being approved by the FDA for use in humans.”
 Mr. Schmidt continued “We believe our product is non-toxic, stable, unadulterated, and does not cause airway reactivity. We reached this conclusion after two years of work culminating this past month with Dr. Duane Drinkwine’s breakthrough discovery of a new proprietary method of manufacturing pharmaceutical grade CDB isolate that we believe can be safely delivered to the pulmonary tract without irritation. We will be releasing specific details of this discovery in the next month or two.”
 While the application process is pending with the FDA, RTSL plans to utilize its existing lab equipment to continue to develop and manufacture non-MDI aerosol products for sale to the growing hemp product market.
