In brief

Coronavirus disease (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents a major threat to human health. SARS-CoV-2 is highly infectious and is associated with extensive morbidity and mortality. Our study shares important features with other clinical trials using supplements or other widely available medications (e.g., Ascorbic Acid, Zinc, Vitamin D, Vitamin C). Our study shares two important elements with these previous studies, including: 1. The use of adaptive and cost-effective study design methods, 2. The testing of prophylactic supplementation using known, natural substances that have demonstrated safety and limited side effects. The focus of this study is to use a supplement that combines Cannabidiol and Gigartina Red Algae in creating "CBDRA60", a sublingual tablet, which is hypothesized to help reduce the duration of symptoms in patients diagnosed with the novel coronavirus disease (COVID-19). The rationale and design of our trial (N=60), is as follows: 60 individuals newly diagnosed with COVID-19 infection will be randomized to one of two groups. They will either receive CBDRA60 (30mg CBD, 30mgRA / 60mg combo; 2x/daily with food or 120 mg total) or a placebo in a 1:1 ratio. The study duration will be 5 weeks. The primary outcome for newly diagnosed individuals is the prevention of disease progression which leads to hospitalization. The secondary outcome is a reduction in symptom severity scores. COVID-19 patients with weakened innate immune systems may be susceptible to more severe disease and higher mortality. An impaired host immune response may lead to higher SARS-COV-2 viral load and subsequent overactivation of the adaptive immune system that results in cytokine release syndrome. CBD and Gigartina Red Algae can modulate both the innate and adaptive immune responses, have anti-viral activity and thereby can suppress the consequent hyperinflammatory response. Viral infection activates a pathological inflammatory response to combat the pathogen and limit its spread. Viral pathogens, such as the severe acute respiratory syndrome (SARS) coronaviruses (SARS-CoV), and other viruses (such as HIV), have been linked to many human and animal diseases. Advancements in research over the past decade, has led to a better understanding of SARS-CoV biology and the mechanism by which this family of viruses, the coronaviridae, infect and enter the host cells (refs). SARS-CoV-2, a unique type of coronavirus, inhibits host defense by invading host cells, replicating, and infecting numerous tissues. Severe COVID-19 is associated with a cytokine storm, acute respiratory distress and consequent multiple organ pathology that can be fatal. This depictive storm is a result of increase in circulating levels of various proinflammatory cytokines including IL-6, IL-1 TNF-α as well as interferons (IFN-I; IFNα and IFNβ). CBD CBD is a non-psychotropic cannabinoid that has a broad spectrum of well-established anti-inflammatory and immunomodulatory effects. For example, CBD administration in a murine model of lung injury, reduces lung inflammation through inhibition of immune cell cytokine production and suppression of leukocyte infiltration. Our premise is that similar CBD-induced effects would be highly applicable and hugely beneficial to mitigating the acute respiratory distress syndrome observed in COVID-19. Published evidence also indicates that CBD can inhibit viral replication. Red algae (Rhodophyta) are known for their potent anti-viral properties, non-toxicity and for being well tolerated in humans. Rhodophyta contain several sulfated polysaccharides that exhibit high antiviral activity against enveloped viruses, including important human pathogens such as herpes simplex virus (HSV), human cytomegalovirus, dengue virus and respiratory syncytial virus. Sulfated polysaccharides can exert their anti-viral effects through interacting with the external glycoprotein of the virion envelope preventing attachment of the virus to cell surface receptors. Red algae also contain mannose specific lectins that specifically interact with viral envelope glycoproteins including the spike glycoprotein specific to SARS-CoV2 to inhibit viral entry. It is our premise that by using a safe and tolerable dose of the formulated CBDRA60 sublingual tablet, participants could either be protected from viral infection of the SARS-CoV-2 virus (COVID-19) or in subjects that are already infected, CBDRA60, could prevent virus attachment, mitigate virus-induced inflammation and avoid a cytokine storm, enabling a faster recovery.
