COVID-19 Clinical Trials and Expanded Access

To determine if the reduction in TMPRSS2 activity via direct inhibition with Camostat mesilate combined with standard of care (SOC) treatment will increase the proportion of patients alive and free from respiratory failure at Day 28 in SARS-CoV-2 as compared to SOC treatment with placebo.

SARS-CoV-2 is the novel coronavirus responsible for COVID-19, coronavirus disease 2019. This new coronavirus was first detected in Wuhan, China in late December 2019. According to WHO, the incidence rate of COVID-19 is prominent among adults and elderly people, reaching so far >2 million cases globally. Meanwhile, confirmed death cases reached >126 thousands of reported cases in 185 countries and still increasing. We anticipate that immunological differences among COVID19-infected patients might be a reason behind the variation of patient outcomes. Therefore, we intend to investigate cellular and humoral immune responses of COVID19-positive patients, and we claim to discover new indicators of patients' prognosis. Our target population includes three categories of patients staying at ICU, HMC (COVID19-positive vs. COVID19-negative vs. healthy control). Throughout their ICU stay, multiple blood samples will be screened for leukocytes surface markers, leukocytes' production of certain molecules, and circulating cytokines/chemokines/checkpoint inhibitors. Their plasma/serum will be used as well for immune proteomics, metabolomics, and other serological tests. Such parameters can provide the more comprehensive status of COVID19-infected patients at infection onset, during treatment intake, and at recovery or relapse stage. Following analysis, the main prospective outcome of this study is to identify the most reflective markers of COVID19-positive patients' outcomes.

This is a multi-center study comparing clinical outcomes in patients with COVID-19 in subjects hospitalized at Hadassah and other hospitals for PCR or serology confirmed COVID-19 and compare the outcomes to the presence of different degrees of a cytokine storm. The patients will be subdivided into a mild, moderate, and severe course according to NEWS2.

Severe acute respiratory syndrome coronavirus 2 (COVID-19) poses substantial challenges for health care systems. With a vastly expanding amount of publications on COVID-19, clinicians need evidence synthesis to produce guidance for handling patients with COVID-19.

A clinical and experimental study will be carried out in which the clinician will investigate the PCR of the virus early in different body fluids (blood, semen, urine, saliva) and monitor its experimental clearance and evaluate in vitro diagnostic tests and inhibitory factors of viral proliferation.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first appeared in China, in December 2019 and is now spreading worldwide and poses a great threat to public health. In 12th July 2020, the total number of cases worldwide was about 13 million cases with case fatality rate of 4.4% and in Egypt the total cases was 81158 and case fatality rate was 4.6%. (1,2). In recent years, novel coronaviruses emerge periodically in different areas around the world. Severe acute respiratory syndrome coronavirus (SARS-CoV) occurred in 2002, which reportedly infected 8422 people with about 10% case fatality rate (3). Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in 2012 in Saudi Arabia, bringing a total of 1401 MERS-CoV infections, and about 35% case fatality rate (1). All the infection cases and recent epidemics show that coronaviruses impose a continuous threat to human beings and the economy as they emerge unexpectedly, spread easily, and lead to catastrophic consequences. As the number of recovered patients with COVID-19 continues to be increasing, the strength and duration of immunity after infection is an important point to be studied. Moreover, understanding this issue is a critical point for controlling this epidemic as they are the key for herd immunity and for informing decisions on how and when to ease physical distancing restrictions and to be ready for other waves of the infection. There is currently no evidence if the people who have recovered from COVID-19 have antibodies and protected from a second attack of infection or future wave of this pandemic or not. Therefore, we will carry out a longitudinal study of immunity in recovered patients to assess SARS-Cov2 patients' risk for future reinfection.

The recent COVID-19 outbreak has put the health care workers on the frontline to interact and provide support to the patients. Based on previous disease outbreak-associated studies, it is evident that these individuals are at a high-risk of developing psychological distress such as burnout, anxiety, depression, and stress (BADS). Thus, the current study aims to evaluate the mental health outcomes of healthcare workers dealing with COVID-19 patients within Qatar and internationally, during and after the COVID-19 crisis. The participants will be divided into two groups: those working with COVID-19 patients and those not working with COVID-19 patients. The magnitude of symptoms of BADS will be assessed using electronic versions of the standardized questionnaires: Maslach Burnout Inventory (MBI-HSS), Hospital Anxiety and Depression Scale (HADS), Depression, Anxiety and Stress Scale (DASS-21), and Conditions for Work Effectiveness (CWEQ). A follow-up survey will be sent to both groups after the COVID-19 crisis to assess their vulnerability to develop post-trauma stress disorder (PTSD) using a PDS-5 survey.

There are currently no antiviral drugs with proven efficacy nor are there vaccines for its prevention. Unfortunately, the scientific community has little knowledge of the molecular details of SARS-CoV-2 infection. The drugs we are chosen are used as clinical trials for antiviral and there is no proven guide for specificity and effectiveness against the virus so the results are different Now the clinical trials and research authorities are work speedily to target the most proven treatment for the virus so anything is infantile until now. the covid-19 with time be more explained by scientists it is steroid response disease and cause thromosis and cytokine storm , the aim of the study to inhibit viral replication and decrease the severity of the disease as antiviral and anticytokine storm , antithrombosis Zinc is a mineral element needed to regulate adaptive immune cells' functions. Higher level of intracellular zinc showed to increase intracellular pH; which affect on RNA-dependent RNA polymerase and decrease replication mechanism of RNA viruses. Therefore, drugs that described as zinc ionophores could be used with zinc supplement to act as antiviral against many RNA viruses including SARS-CoV-2 Quercetin is natural compound act as zinc ionophore to cause zinc influx intracellular. Quercetin is a safe natural anti-oxidant and anti-inflammatory polyphenolic compound that found in various natural sources include onion, red grapes, honey and citrus fruits. It was shown that quercetin has the ability to chelate zinc ions and act as zinc ionophore. Therefore, quercetin could have antiviral activity against many RNA viruses . Quercetin, a flavonoid found in fruits and vegetables, has unique biological properties that may improve mental/physical performance and reduce infection risk ; These properties form the basis for potential benefits to overall health and disease resistance, including anti-carcinogenic, anti-inflammatory, antiviral, antioxidant, and psychostimulant activities, as well as the ability to inhibit lipid peroxidation, platelet aggregation and capillary permeability, and to stimulate mitochondrial biogenesis .There are various studies that report the immunomodulatory effect of bromelain . Bromelain activates natural killer cells and augments the production of granulocyte-macrophage-colony stimulating factor, IL-2, IL-6 and decreases the activation of Thelper cells. Thus, bromelain decreases the majority of inflammatory mediators and has demonstrated a significant role as an anti-inflammatory agent in various conditions Vitamin C is known as an essential anti-oxidant.,and enzymatic co-factor for physiological reactions such as hormone production, collagen synthesis and immune potentiation . Naturally, an insufficiency of vitamin C leads to severe injuries to multiple organs, especially to the heart and brain, since they are both highly aerobic organs that produce more oxygen radicals. In fact, studies of in vivo effect on vitamin C are difficult since most animals, except human and some primate, are capable of synthesizing vitamin C endogenously

This study is an observational study (Non-interventional study) to evaluate the safety and efficacy of favipiravir in patients older than 15 years of age, diagnosed with COVID-19 and initiated treatment with favipiravir before enrollment to the study. Patients who have already had a routine favipiravir treatment decision or alternatively favipiravir treatment started at the time of enrollment, will be included in this study.

Coronavirus Disease 19 (COVID-19) is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Severe disease occurs in 15% of the cases with COVID-19 and may progress to critical disease in only 5% of the cases with a high risk of mortality. Critical disease may present as acute respiratory failure secondary to Acute Respiratory Distress Syndrome (ARDS) and is caused by the body's hyper-immune response to the virus in the form of a cytokine storm syndrome (CSS). There is currently no effective anti-viral treatment against SARS-CoV-2 and the mainstay of treatment is supportive. Co-trimoxazole (combination of trimethoprim and sulphamethoxazole in a 1:5) ratio is a Sulphur containing anti-folate bactericidal antibiotic indicated for the treatment of respiratory tract infections. It has been around for over 60 years and is inexpensive and readily available with a good safety profile. It has a rapid onset of action with excellent bioavailability and lung penetration. In addition to having antimicrobial properties co-trimoxazole have immunomodulatory and anti-inflammatory properties and may be a potential treatment option for cytokine storm syndrome mediated severe COVID-19. This open-label randomized controlled trial will be conducted in the department of medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Anwar Khan Modern Medical college and Mughda Medical College Hospital (DMCH), Dhaka for a duration of 6 months following approval of this protocol. It will recruit at least 94 consecutive adults (18 years or older) patients with clinically suspected COVID-19 and severe illness as per WHO criteria. After taking informed written consent patients will be randomly assigned in a 1:1 ratio to either oral co-trimoxazole in addition to standard therapy or standard therapy alone. Baseline characteristics, changes in the physiological and biochemical parameters like (SpO2/FiO2 ratio, respiratory rate, body temperature and C - reactive protein), length of hospital stay, side effects of drugs, requirement for ventilatory support (non-invasive and invasive ventilation) and in-patient mortality between the two groups will be compared. Conclusion If the results from this clinical trial demonstrate the beneficial effects of co-trimoxazole in severe COVID-19 patients it could be used widely, thereby reducing the need for respiratory support and potentially saving thousands of lives in developing nations with limited resources where healthcare may be easily overwhelmed.
