EFFICACY and SAFETY OF BEVACIZUMAB (ZIRABEV®) IN PATIENTS WITH SEVERE HYPOXEMIC COVID-19

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.

Clinical Study Designed to Evaluate the Effect of CimetrA in Patients Diagnosed With COVID-19

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-1?, interleukin-6, IP-10, TNF, interferon-?, macrophage inflammatory protein (MIP) 1? and 1?, 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).
