Efficacy of Nafamostat in Covid-19 Patients (RACONA Study)
COVID19RACONA is a prospective trial that will test the hypothesis that nafamostat can lower lung function deterioration and need for intensive care admission in COVID-19 patients. Design: Adult hospitalized COVID-19 patients will be randomized in a prospective double-blind randomized placebo-controlled study to test the clinical efficacy of nafamostat mesylate (administered intravenously) on top of best standard of care. Primary outcome measures: the time-to-clinical improvement, defined as the time from randomization to an improvement of two points (from the status at randomization) on a seven category ordinal scale or live discharge from the hospital, whichever comes first.

Covid19 PneumoniaTitle: The use of Tocilizumab in the management of patients who have severe COVID-19 with suspected pulmonary hyperinflammation. This is a study designed to assess the therapeutic value of intravenous tocilizumab administered as single 8mg/Kg dose in patients affected by SARS-CoV2 infection with a pulmonary manifestation causing hypoxia. Aim of the study is to test the hypothesis that anti-IL6 treatment can be effective in reducing the virus-induced cytokine storm, blocking deterioration of lung function or even promoting a rapid improvement of clinical conditions, preventing tracheal intubation and/or death. This drug will be administered to those patients entering the ICU with severe acute respiratory failure COVID-19 disease. The endpoints are death and duration of hospitalization. The patients will be assessed with surrogate markers determining the level of the cytokine storm.

COVIDCombination of Recombinant Bacterial ACE2 receptors -like enzyme of B38-CAP and Isotretinoin could be promising treatment for COVID-19 infection- and Its inflammatory complications Mahmoud ELkazzaz1 1Department of chemistry and biochemistry, Faculty of Science, Damietta University, Egypt. _____________________________________________________________________________________________________________________________________________________________________ B38-CAP is a bacteria-derived ACE2-like enzyme that suppresses hypertension and cardiac dysfunction Angiotensin-converting enzyme 2 (ACE2) is critically involved in cardiovascular physiology and pathology, and is currently clinically evaluated to treat acute lung failure. Here we show that the B38-CAP, a carboxypeptidase derived from Paenibacillus sp. B38, is an ACE2-like enzyme to decrease angiotensin II levels in mice. In protein 3D structure analysis, B38-CAP homolog shares structural similarity to mammalian ACE2 with low sequence identity. A study demonstrated that the bacterial B38-CAP as an ACE2-like carboxypeptidase, indicating that evolution has shaped a bacterial carboxypeptidase to a human ACE2-like enzyme. Bacterial engineering could be utilized to design improved protein drugs for hypertension and heart failure. pretreatment of B38-CAP markedly down regulated a massive increase of plasma Ang II levels at 5 min after Ang II injection In addition to the currently used drugs to inhibit Ang II generation or signaling, such as ACE inhibitors or Angiotensin receptor blockers, direct down-modulation of Ang II levels by rhACE2 protein is one of the promising candidates for new therapeutic strategy in cardiovascular disease and other Ang II-related diseases, e.g. ARDS. On the other hand, although mass production of rhACE2 as a protein drug costs due to requirement of mammalian cell expression systems, B38-CAP is easily prepared with E. coli expression system and is cost effective. Therapeutic efficacy and less toxicity in mouse heart failure models would warrant further investigation of B38-CAP or other microbial carboxypeptidases in disease models. Finally the principal investigator expects that treatment with ACE2-like enzyme of bacteria B38-CAP expected to work efficiently Like human ACE2 and it will save the lung cells from COVID - 19 inhibitory effect and down regulation of ACE2 because COVID-19 binds to human ACE2 and down regulates it and this receptors is very important for lung cells survival and function So ,the principal investigator also expects that B38-CAP ACE2 like enzyme may be not recognized by COVID -19 spike protein because evolutionary it is too far away from human ace2 and human ACE2 is a real receptor of COVID -19 not ACE2 like enzyme but in the same time it will make the same function of human ACE2 In another study by Sinha et al who analyzed a publicly available Connectivity Map (CMAP) dataset of pre/post transcriptomic profiles for drug treatment in cell lines for over 20,000 small molecules, isotretinoin was the strongest down-regulator of ACE 2 receptors. On the other hand, they found 6 drugs in CMAP that are currently being investigated in clinical trials for treating COVID-19 (chloroquine, thalidomide, methylprednisolone, losartan, lopinavir and ritonavir, from clinicaltrials.gov), none of which was found to significantly alter ACE2 expression (P>0.1) Moreover, another study demonstrated that isotretinoin is a Potential papain like protease (PLpro) inhibitors which is a protein encoded by SARS-CoV-2 genes and considered one of the proteins that should be targeted in COVID-19 treatment by performing target-based virtual ligand screening . So, the principal investigator expects strong inhibition of COVID - 19 infection And rescuing the lung cells from its serious attack by treating with ACE2 like enzyme and Isotretinoin Keywords: COVID 2019 , Isotretinoin,B38-CAP , Bacterial ACE2 receptors -like enzyme , rhACE226.

Assess the Safety and Efficacy of Convalescent Plasma to Limit COVID-19 Associated Complications...
COVID 19The novel coronavirus disease (COVID-19), which began in Wuhan, China, in December 2019, has been declared to be a pandemic by the World Health Organization (WHO), Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), COVID-19 has resulted in 1,781,127 cases and 108,994 deaths globally (till 12th April, 2020), affecting 199 countries and 2 international conveyances. US FDA has recently approved Convalescent Plasma from patients recovered from COVID 19 for the treatment of severe or life threatening COVID-19 infections. In a small case series, five critically ill COVID-19 patients with ARDS were treated with convalescent plasma containing neutralizing antibodies. Infusion of plasma was followed by improvement in clinical status in all five patients, with no deaths and the study reported that three patients were discharged, whilst two continued to be stable on mechanical ventilation. We designed this phase II, open label, randomized clinical trial with the primary objective to assess the safety and efficacy of the therapy in the second stage.

Vielight RX Plus for the Treatment of COVID-19 Respiratory Symptoms
COVID-19The objective of this study is to obtain data on the efficacy of the Vielight RX Plus in decreasing time to recovery of symptoms in subjects with COVID-19. The study will be conducted among COVID-19 positive subjects at home in self-isolation via electronic data collection (EDC). There will be no physical contact between the subjects and the Qualified Investigator (QI) or other study staff. This study aims to demonstrate that the Vielight RX Plus is a useful adjunct to standard of care (SOC). We hypothesize that the Vielight RX Plus will accelerate recovery and reduce viral infection severity.
