clinical study designed to evaluate the effect of cimetra in patients diagnosed with covid-19

Conditions: Corona Virus Infection; Covid19; SARS-CoV Infection

Summary: a preparation of cimertra, comprising artemisinin, curcumin, and boswellia, and vitamin c in a nanoparticular formulation, is proposed as a treatment for the disease associated with the novel coronavirus sars-cov-2. this initiative is presented under the urgent circumstances of the fulminant pandemic caused by this lethal disease, which is known as covid-19 and has spread across the globe causing death and disrupting the normal function of modern society. the grounds for the proposal are rooted in existing knowledge on the components and pharmacological features of this formulation and their relevance to the current understanding of the disease process being addressed. the severe acute respiratory syndrome-associated coronavirus disease 2019 (covid-19) illness results from the immediate response to the viral infection as well as from a subsequent host inflammatory response. systemic proinflammatory cytokines and biomarkers are elevated as the disease progresses towards its advanced stages, and correlate with worse chances of survival. serum cytokine levels that are elevated in patients with covid-19-associated cytokine storm include interleukin-1β, interleukin-6, ip-10, tnf, interferon-γ, macrophage inflammatory protein (mip) 1α and 1β, and vegf. higher interleukin-6 levels are strongly associated with shorter survival. the relative frequencies of circulating activated cd4+ and cd8+ t cells and plasmablasts are increased in covid-19. in addition to the elevated systemic cytokine levels and activated immune cells, several clinical and laboratory abnormalities, such as elevated crp and d-dimer levels, hypoalbuminemia, renal dysfunction, and effusions, are also observed in covid-19. laboratory test results reflecting hyper inflammation and tissue damage were found to predict worsening outcomes in covid-19. cimetra, comprising artemisinin, curcumin, boswellia, and vitamin c in a nanoparticular formulation, has been studied on patients with covid-19 in a randomized double-blind control phase ii study (mgc-006 - under a previous product name - artemic). the study product demonstrated excellent safety and efficacy profiles. experiments performed in vitro with cimetra demonstrated the ability to reduce cytokine elevation in response to stimulation of human pbmc preparations. the currently proposed multi-center multinational-controlled study is designed to include 252 adult patients who suffer from moderate covid-19 infection. safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments, and vital signs. after the screening visit, the study drug will be administrated twice a day morning and evening (every 12 hours) during (day 1 and day 2) the patients will be randomized in 1:1:1 ratio to study drug (cimetra) in addition to standard of care (arm 1 (cimetra-1) or arm 2 (cimetra-2)) or placebo in addition to standard of care (arm 3).

the study will take place during the patient's hospitalization due to a covid-19 infection. the study will last up to 4 weeks, until the conclusion on day 28. in case of hospital discharge within the study period, follow-up will continue per protocol until day 28 wherever the subject will be located, performed via phone call or in-clinic, depending on the status of the patient and study schedule. 252 adult patients who suffer from covid-19 infection and do not participate in any other clinical trial. the patient must not agree to participate in any new clinical study during the study duration. the study will take place during the patient's hospitalization due to a covid-19 infection. the study will last up to 4 weeks, until the conclusion on day 28. in case of hospital discharge within the study period, follow-up will continue per protocol until day 28 wherever the subject will be located, performed via phone call or in-clinic, depending on the status of the patient and study schedule. day 1 prior to engaging in any study procedures, the subject must meet the inclusion/exclusion criteria by history (which includes a signed declination), and review and sign an icf. following procedures will be performed during the visit -
