5 Multi-centre, Adaptive, Randomized Trial of the Safety and Efficacy of Treatments of COVID-19 in Hospitalized Adults

This study is a multi-centre, adaptive, randomized, open clinical trial of the safety and efficacy of treatments for COVID-19 in hospitalized adults. The study is a multi-centre/country trial that will be conducted in various sites in Europe with Inserm as sponsor. Adults (≥18 year-old) hospitalized for COVID-19 with SpO2 ≤ 94% on room air OR acute respiratory failure requiring supplemental oxygen or ventilatory support will be randomized between 4 treatment arms, each to be given in addition to the usual standard of care (SoC) in the participating hospital: SoC alone versus SoC + Remdesivir versus SoC + Lopinavir/Ritonavir versus SoC + Lopinavir/Ritonavir plus interferon ß-1a versus SoC + Hydroxychloroquine. Randomization will be stratified by European region and severity of illness at enrollment (moderate disease: patients NOT requiring non-invasive ventilation NOR high flow oxygen devices NOR invasive mechanical ventilation NOR ECMO and severe disease: patients requiring non-invasive ventilation OR high flow oxygen devices OR invasive mechanical ventilation OR ECMO). The interim trial results will be monitored by a Data Monitoring Committee, and if at any stage evidence emerges that any one treatment arm is definitely inferior then it will be centrally decided that that arm will be discontinued. Conversely, if good evidence emerges while the trial is continuing that some other treatment(s) should also be being evaluated then it will be centrally decided that one or more extra arms will be added while the trial is in progress. The primary objective of the study is to evaluate the clinical efficacy and safety of different investigational therapeutics relative to the control arm in patients hospitalized with COVID-19, the primary endpoint is the subject clinical status (on a 7-point ordinal scale) at day 15.

8 Evaluation of the Safety and Clinical Efficacy of Hydroxychloroquine Associated With Azithromycin in Patients With Pneumonia Caused by Infection by the SARS-CoV2 Virus - Coalition COVID-19 Brasil II - Severely-ill Patients

The Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV2) is a new and recognized infectious disease of the respiratory tract. Around 20% of those infected have severe pneumonia and currently there is no specific or effective therapy to treat this disease. Therapeutic options using malaria drugs chloroquine and hydroxychloroquine have shown promising results in vitro and in vivo test. But those efforts have not involved large, carefully-conducted controlled studies that would provide the global medical community the proof that these drugs work on a significant scale. In this way, the present study will evaluate the effectiveness and safety of the use of hydroxychloroquine combined with azithromycin compared to hydroxychloroquine monotherapy in patients hospitalized with pneumonia by SARS-CoV2 virus.

11 Hydroxychloroquine Versus Placebo in Patients Presenting COVID-19 Infection and at Risk of Secondary Complication: a Prospective, Multicentre, Randomised, Double-blind Study

A new human coronavirus responsible for pneumonia, SARS-CoV-2, emerged in China in December 2019 and has spread rapidly. COVID-19, the disease caused by this virus, has a very polymorphous clinical presentation, which ranges from upper respiratory tract infections to acute respiratory distress syndrome. It may appear serious straightaway or may evolve in two stages, with a worsening 7 to 10 days after the first clinical signs, potentially linked to a cytokine storm and accompanied by a high risk of thrombosis. The global mortality rate of COVID-19 is between 3% and 4%, with severe forms being more frequent among older patients. Management is symptomatic as no antiviral treatment has demonstrated any clinical benefit in this condition. Hydroxychloroquine is a derivative of chloroquine commonly used in some autoimmune diseases, such as systemic lupus erythematosus. It is active in vitro in cellular models of infection by many viruses such as HIV, hepatitis C or SARS-CoV. However, its interest in viral infections in humans has not been demonstrated. Very recently, a preliminary uncontrolled study evaluated the effect of hydroxychloroquine on viral shedding in subjects with COVID-19. Among 20 patients treated with hydroxychloroquine at a dose of 600 mg per day, the percentage of patients with detectable SARS-CoV-2 RNA in the nasopharynx decreased from 100% at inclusion (start of treatment) to 43% six days later. In comparison, 15 of 16 untreated patients had a positive RT-PCR six days after inclusion. Furthermore, hydroxychloroquine has immunomodulating and anti-inflammatory properties, which could theoretically prevent or limit secondary worsening. The research hypothesis is that treatment with hydroxychloroquine improves prognosis and reduces the risk of death or use for invasive ventilation in patients with COVID-19.

12 Chemoprophylaxis of SARS-CoV-2 Infection (COVID-19) in Exposed Healthcare Workers : A Randomized Double-blind Placebo-controlled Clinical Trial

Since December 2019, the emergence of a new coronavirus named SARS-Cov-2 in the city of Wuhan in China has been responsible for a major epidemic of respiratory infections, including severe pneumonia. Within weeks, COVID-19 became a pandemic. In the absence of specific antiviral treatment, a special attention should be given to prevention. Personal protection equipments may be insufficiently protective, including in healthcare workers, a significant proportion of whom (around 4%) having been infected in the outbreaks described in China and more recently in Italy. Infection in healthcare workers could result from the contact with COVID-19 people in community or with infected colleagues or patients. As it will take at least a year before vaccines against SARS-CoV-2 becomes available, chemoprophylaxis is an option that should be considered in this setting where prevention of SARS-CoV-2 infection in Health Care Workers. The COVIDAXIS trial evaluates a chemoprophylaxis of SARS-CoV-2 infection in Health Care Workers. This trial is divided into two distinct studies that could start independently each with its own randomization process: COVIDAXIS 1 will study Hydroxychloroquine (HCQ) versus placebo; COVIDAXIS 2 will study Lopinavir/ritonavir (LPV/r) versus placebo. Upon randomization healthcare workers (HCWs) involved in the management of suspected or confirmed COVID-19 cases will be assigned to one of the following 2 treatment groups:

14 A Randomized, Double-blind, Placebo-controlled Trial to Assess the Efficacy and Safety of Oral Hydroxychloroquine for the Treatment of SARS-CoV-2 Positive Patients for the Prevention of Severe COVID-19 Disease.

Albertans with COVID-19 are at risk of deteriorating and developing severe illness. Those over age 40 or with co-morbid illness, and likely those who are immune suppressed, are at highest risk. This study will include a focus on people with immune-suppressed states. Individuals confirmed to have SARS-CoV-2 infection will be identified using administrative data (positive lab result, age 18 or over, not hospitalized, and not living in SL4 level of care). They will then be contacted by AHS staff, independent of the researchers, to obtain their consent for the researchers to contact them about this trial. The AHS staff member who contacts the individual will enroll consenting individuals into a study database. If they provided an email address an email will automatically be sent to the individual with study information. Those who decline to be contacted will also be informed of the study website so they can choose to review the study information and self-enrol, although they will need to do so quickly to meet study timelines. Enrolled participants will be contacted by a study coordinator. Those without access to the internet will be informed about the study details when they are contacted by a study coordinator. When the study coordinator contacts potential participants the study will be reviewed, and the potential participant will have an opportunity to ask questions. Consent for participation will be obtained by telephone. Telephone consent will be recorded. Participants will then be screened for inclusion and exclusion criteria by telephone interview and review of Alberta Netcare. Alberta Netcare is the province of Alberta's public Electronic Health Record used to store patient information so that it is easily accessible to healthcare professionals for the purpose of care. Information like immunizations, ECG results, diagnostic images and reports, written medical reports (e.g. surgery reports, consultations, hospital admissions), diagnostic lab testing results (e.g. blood tests, urine tests, blood bank info), allergies and intolerances (drug and food allergies, food intolerances), prescription history, and general patient information (e.g. name, birthdate, personal health number, address, phone number). Those who are not eligible for the study will be informed of the reason(s) for ineligibility (generally it will be a safety exclusion and they should be aware of this). Those who are eligible will be randomized to receive HCQ or placebo for a total duration of 5 days. Study drug will be delivered to their residence by courier. Telephone follow-up will occur at day 7 (range 7-10 days) and at day 30 (range 25-35 days).

15 A Trial of Ciclesonide Alone or in Combination With Hydroxychloroquine for Adults With Mild COVID-19

According to In vitro studies, ciclesonide showed good antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although some cases were reported for the clinical effectiveness of ciclesonide in the treatment of COVID-19, there is no clinical trial to evaluate the antiviral effect on the reduction of viral load in patients with COVID-19. In this study, we aimed to investigate whether ciclesonide alone or in combination with hydroxychloroquine could eradicate SARS-CoV-2 from respiratory tract earlier in patients with mild COVID-19.

28 Low-dose Hydroxychloroquine for Primary Prophylaxis Against SARS-CoV-2 in Health-care Workers - a Randomized, Double-blind, Controlled Trial

Background: Aim: To demonstrate the efficacy of low-dose hydroxychloroquine as primary prevention in healthcare workers Design, participants and interventions: Prospective, randomized, parallel group, double-blinded, placebo controlled, study. including 440 participants who will be randomised to 2 treatment arms: hydroxychloroquine or placebo. Outcome variables: symptomatic or asymptomatic SARS-CoV-2 infection confirmed by PCR, viral load during SARS-CoV-2 infection, seroconversion during the study period, incidence of any acute respiratory infection, days of sick leave. Statistical considerations: No trials have been published investigating the efficacy of HCQ as primary prophylaxis of SARS-CoV-2 infection in health care workers. Thus, sample size calculations in the proposed trial are based on the investigators' best estimates for several parameters. In accordance to the effect of oseltamivir against symptomatic influenza, we assumed an approximate effectiveness of approximately 60% (HR of 0.4) (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6464969/) as realistic. As a prophylactic intervention with HCQ, which may have side effects and for which supply shortage can be expected, was judged justifiable only if its effectiveness is high, we based our sample size consideration on a HR of 0.3. To estimate the probability of an event in both the experimental and the control group, very little data is available. In a Dutch point-prevalence study 0-10% of health-care workers were infected depending on the healthcare institution, depending on the hospital. This point-prevalence study was performed between 6 and 9 March, when the reported number of cases in the Netherlands was 33 and 77, respectively, according to the RIVM (https://www.rivm.nl/nieuws/resultaat-steekproef-4-ziekenhuismedewerkers-heeft-coronavirus). Additionally, in an a report published in the Lancet, 20% of responding healthcare workers in Italy were found to be infected with SARS-CoV2 within less than one month (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30627-9/fulltext). Several media reports indicate that this proportion is similar across various healthcare institutions and countries (https://www.nytimes.com/2020/03/24/world/europe/coronavirus-europe-covid-19.html) and (https://www.aljazeera.com/news/2020/03/spain-tightens-restrictions-week-lockdown-begins-2003 30191539568.html). As the proposed study will be performed in a high-risk setting, we assumed an event (i.e. PCR positivity) probability of 10% in the control group and 3% in the experimental arm after the maximum study period. In summary, a sample size of 210 participants per arm is necessary to detect a HR of 0.3 with a power of 80.3% with an alpha-error of 0.05. To account for drop-outs and asymptomatic, undetected infection at inclusion or past infection with existing immunity, an additional 10 participants will randomized per treatment arm. The overall study population is therefore 440 participants. Statistical analysis will be based on two populations: A Modified Intention to Treat population excluding those who withdrew consent after randomization and those with a positive serology at baseline. And a per protocol population including all randomized subjects who completed at least 3 out of 4 follow-up visits and took at least 80% of all doses of study medication.

32 Hydroxychloroquine for the Treatment of Mild COVID-19 Disease

The current outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is a global health emergency with a case fatality rate so far approximately 4% and a growing number of confirmed cases (>57.000) in Germany. There is no data available on the efficacy of antiviral agents for the treatment of COVID-19. In-vitro data show that hydroxychloroquine can inhibit SARS-CoV-2 [1] replication and anecdotal reports from Chinese COVID-19 patients [2, 3] suggest that chloroquine is a good candidate for treatment. No data have been published and reported evidence is based on non-controlled use of hydroxychloroquine. The aim of this placebo-controlled trial is to assess the effect of hydroxychloroquine on duration of symptoms in mild COVID-19 patients and time of virus shedding as an important tool to reduce the risk of further community transmissions. This data will inform practice for the design of larger trials on clinical efficacy of hydroxychloroquine in the treatment and post- and preexposure prophylaxis of COVID-19 and as a tool for reduction of community transmission.

Coronaviruses (CoV) are positive-sense single-stranded RNA viruses that infect a wide range of hosts producing diseases ranging from the common cold to serious / fatal events. Nitazoxanide (NTZx) is a derivative of 5-nitrothiazole, synthesized in 1974 by Rosignol - Cavier. NTZx has powerful antiviral effects through the phosphorylation of protein kinase activated by double-stranded RNA, which leads to an increase in phosphorylated factor 2-alpha, an intracellular protein with antiviral effects. The purpose of this study is to contrast the beneficial effect of NTZx vs NTZx plus hydroxychloroquine in patients Coronavirus Disease (COVID-19) as well as against other treatments.

35 Efficacy of Sarilumab + Azithromycin + Hydroxychloroquine, and Sarilumab Alone, for Adult Patients Hospitalized With Moderate to Severe COVID-19: a Multicenter Open-label 1:1 Randomized Controlled Trial

The overall objective of the study is to determine the therapeutic effect and tolerance of Sarilumab in combination with Azithromycin and Hydroxychloroquine, compared to Sarilumab only, patients with moderate, severe pneumonia associated with Coronavirus disease 2019 (COVID-19). Sarilumab is a human IgG1 monoclonal antibody that binds specifically to both soluble and membrane-bound IL-6Rs (sIL-6Rα and mIL-6Rα) and has been shown to inhibit IL-6-mediated signaling through these receptors. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering investigational treatments administration to patients enrolled in the CORIMUNO-19 cohort (NCT04324047). Sarilumab+Azithromycin+Hydroxychloroquine, or Sarilumab only will be administered to consenting adult patients hospitalized with COVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation. All patients will receive standard of care along with randomized investigational treatments. Outcomes of included patients will be compared between groups as well as with outcomes of patients in the CORIMUNO-19 cohort treated with other immune modulators or standard of care.

36 Hydroxychloroquine for Outpatients With Confirmed COVID-19

A novel coronavirus, SARS-CoV-2, is responsible for a rapidly spreading pandemic that has reached 160 countries, infecting over 500,000 individuals and killing more than 24,000 people. SARS-CoV-2 causes an acute and potentially lethal respiratory illness, known as COVID-19, that is threatening to overwhelm health care systems due to a dramatic surge in hospitalized and critically ill patients. Patients hospitalized with COVID-19 typically have been symptomatic for 5-7 days prior to admission, indicating that there is a window during which an effective intervention could significantly alter the course of illness, lessen disease spread, and alleviate the stress on hospital resources. There is no known treatment for COVID-19, though in vitro and one poorly controlled study have identified a potential antiviral activity for HCQ. The rationale for this clinical trial is to measure the efficacy and safety of hydroxychloroquine for reducing viral load and shedding in adult outpatients with confirmed COVID-19.

44 EVALUATION OF THE EFFICACY OF THE HYDROXYCHLOROQUINE-AZITHROMYCIN COMBINATION IN THE IN THE PREVENTION OF COVID-19 RELATED SDRA

Since end of December, a new coronavirus, close to the 2002 SARS coronavirus, cause serious pneumonias throughout world. There is currently no strong evidence of an efficient specific treatment. Hydroxychloroquine is an old chloroquine-derived drug, prescribed for auto-immune disorders. It has shown efficacy against Sars-CoV-2 in vitro. Some studies showed that Hydroxychloroquine might improve the clinical status of Sars-CoV-2 infected patients. Azithromycin is a macrolide antibiotic, with immunomodulatory properties. Adding Azithromycin to a hydroxychloroquine-based treatment showed an apparent accelerated viral clearance in infected patients. This study wants to evaluate the clinical impact of adding Azithromycin to Hydroxychloroquine in the treatment of Sars-CoV-2 pneumonia

48 An Open-label Randomized Controlled Trial on Interferon β-1b and Hydroxychloroquine Combination Versus Hydroxychloroquine Alone, as Treatment for COVID-19 Infection

The novel coronavirus (SARS-CoV-2), is a single-stranded RNA coronavirus. The virus was first isolated from patients presented with pneumonia in Wuhan in December 2019. Sequences of the Wuhan betacoronavirus show similarities to betacoronaviruses found in bats, sharing a common ancestor with the 2003 SARS coronavirus (SARS-CoV) and the bat coronavirus HKU9, a virus found in fruit bats. Similar to SARS-CoV, it is a member of Beta-CoV lineage B. Five genomes of the novel coronavirus have been initially isolated and reported including BetaCoV/Wuhan/IVDC-HB-01/2019, BetaCoV/Wuhan/IVDC-HB-04/2020, BetaCoV/Wuhan/IVDC-HB-05/2019, BetaCoV/Wuhan/WIV04/2019, and BetaCoV/Wuhan/IPBCAMS-WH-01/2019 from the China CDC. The SARS-CoV-2 has since spread from China to the rest of the world. As of 5 April 2020, more than 1.05 million people been confirmed to have infected by SARS-CoV-2, resulting in more than 500,000 deaths. No specific antiviral treatment for the SARS-CoV-2 is currently available, but existing medication could be repurposed. Genetic sequencing demonstrated similarity of the SARS-CoV-2 to the SARS-CoV and MERS CoV.2 We expect patients infected with the SARS-CoV-2 will also present similarly with initial upper respiratory tract symptoms including fever, cough, sputum, myalgia and shortness or breath. More severe cases might complicate with pneumonia and required ventilatory or ECMO support. According to our previous studies in 2003 on patients hospitalized for severe SARS-CoV, the viral load peaked between day 7 from symptoms onset and coincided with clinical deterioration of pneumonia and respiratory failure, with majority of the patients required intensive care support. Higher viral load isolated from different human system also correlated with worsened SARS manifestation and complications. Previously, we have demonstrated that interferon-beta 1b, commonly used in the treatment of multiple sclerosis and lopinavir/ ritonavir, also demonstrated to improve the outcome of MERS-CoV infection in a non-human primate model of common marmoset. A non-randomized trial has also suggested that a combination of hydroxychloroquine and azithromycin might be effective in suppressing SARS-CoV-2 viral load in patients, despite in-vitro activity was only found in hydroxychloroquine. Therefore, we propose to conduct an open-label randomized controlled trial on a short course of interferon β-1b and hydroxychloroquine combination treatment for patients hospitalized for COVID-19 infection.

56 Efficacy of Hydroxychloroquine, Telmisartan and Azithromycin on the Survival of Hospitalized Elderly Patients With COVID-19: a Randomized, Multicenter, Adaptative Study

In November 2019, Wuhan city in China, became the center of an outbreak of pneumonia due to a novel coronavirus SARS-CoV-2, which disease was named coronavirus disease 2019 (COVID19) in February, 2020. The COVID19 is much more dangerous for people over 60 with a death rate of 3.6% after 60, 8.0% after 70 and 14.8% after 80 -and according to our Italian colleagues over 20% after 90- against 2.3% in the general population. The elderly patients who died most often had multiple comorbidities and in particular: cardiovascular disease (10.5% mortality), diabetes (7.3%), chronic respiratory disease (6.3%) and hypertension (6%). These elderly patients with COVID19 are therefore very fragile and require treatment that fights the virus but is also adapted to their state of health and age. Most of current therapeutic trials worldwide exclude people aged over 75 years, which is precisely the age group affected by COVID19. We therefore propose to carry out a therapeutic trial specific to the elderly with drugs at doses that are bearable for these patients. Using the WHO, clinicaltrial, pubmed and the Chinese CCDC/CHCTR websites to find the better drugs adapted to elderly people, we decided after concertation between infectiologists and geriatricians to do a four arms clinical trial during two weeks twice a day: Hydroxychloroquine 200mg, Telmisartan 40mg, Azithromycin 250mg and standard care. We therefore hypothesize that one or more of these treatments may have a beneficial effect in controlling COVID19, without major and repeated side effects in elderly patients.

57 An Open Label Cluster Randomized Controlled Trial of Chloroquine, Hydroxychloroquine or Only Supportive Care in Patients AdmItted With Moderate to Severe COVID-19

Rationale: Currently there are no approved treatments for COVID-19. In the Dutch treatment protocol guideline (SWAB) designated treatment is supportive care with the option to add chloroquine base (CQ) or hydroxychloroquine (HCQ). CQ and HCQ are implemented because of their in vitro activity, results from small animal studies, and anecdotal patient's data. There are no published randomized studies with these medications in patients with disease caused by any coronavirus. Objective: To evaluate if treatment with only supportive care or addition of one of two anti-COVID_19 agents (chloroquine or hydroxychloroquine) results in less disease progression in patients with moderate to severe COVID-19 who require hospital admission. Study design: Multicentre, cluster randomized cross-over, open label trial. Hospitals will be randomly allocated to one of 3 treatment arms in sequential periods of one week: chloroquine base versus hydroxychloroquine versus supportive care without any drug presumed active against SARS-COV-2. Patients will be treated based on the date of inclusion. Study population: Adults aged of 18 years and older with moderate to severe, with a NEWS-2 score ≤ 5, laboratory confirmed COVID-19, who require hospital admission in a ward outside the Medium Care or Intensive Care. Intervention (if applicable): Depending on the treatment arm, the study subject will receive only supportive care or an addition with one of the two agents active against SARS-CoV-2 (chloroquine or hydroxychloroquine). Main study parameters/endpoints: Disease progression defined as a NEWS-2 score ≥ 7 within 14 days, or admission to Medium Care or Intensive Care Unit, or death.

COVID-19 is a respiratory disease due to a novel coronavirus (SARS-CoV-2) that causes substantial morbidity and mortality. To date, no treatment has been proved to be effective in COVID-19. Elderly patients and patients with comorbidities have the worse prognosis with a higher risk of hospitalization, ICU admission and death. The efficacy of an early outpatient treatment could be suggested but need to be confirmed. This confirmation is mandatory to improve prognosis of COVID-19 but also to avoid unsuspected deleterious effect of drugs already used in clinical practice but not based on evidence.

63 Efficacy and Safety of Hydroxychloroquine in Primary Prophylaxis of SARS-CoV-2 Infection in Healthcare Workers at Risk of Exposure: Randomised Control Trial

Healthcare personnel are at an increased risk of exposure to SARS-CoV-2 infection while handling such patients. Currently, there is no treatment available for SARS-CoV-2 and stringent preventive measures are advised to avoid or minimize risk of exposure to healthcare workers. There are in vitro studies available which show inhibition of corona virus by hydroxychloroquine, a widely-used agent against malaria and certain autoimmune conditions and of low-cost and limited toxicity. However, evidence regarding its effects in patients is limited. We plan to conduct a randomized controlled trial to evaluate the safety and potential prophylactic efficacy of hydroxychloroquine in preventing secondary SARS-CoV-2 infection among healthcare workers at high-risk of exposure while managing such patients.

67 A Phase II Randomized Double-Blind Trial of Baricitinib or Placebo Combined With Antiviral Therapy in Patients With Moderate and Severe COVID-19

This phase II trial studies the effect of baricitinib in combination with antiviral therapy for the treatment of patients with moderate or severe coronavirus disease-2019 (COVID-19). Treatment with antiviral medications such as hydroxychloroquine, lopinavir/ritonavir, and/or remdesivir may act against infection caused by the virus responsible for COVID-19. Baricitinib may reduce lung inflammation. Giving baricitinib in combination with antiviral therapy may reduce the risk of the disease from getting worse and may help prevent the need for being placed on a ventilator should the disease worsen compared to antiviral therapy alone.

68 A Randomised Controlled Trial of Early Intervention in Patients HospItalised With COVID-19: Favipiravir Verses HydroxycholorquiNe & Azithromycin & Zinc vErsEs Standard CaRe

Currently we do not know how best to treat patients infected with COVID-19. This study is looking at whether randomising participants to either a combination of azithromycin, hydroxychloroquine and zinc or favipiravir, alongside usual care, can help patients with suspected or proven COVID-19 infection.

69 Randomized, Multi-arm Phase II Trial of Novel Agents for Treatment of High-risk COVID-19 Positive Patients

This is a multi-arm, phase II trial for rapid efficacy and toxicity assessment of multiple therapies immediately after COVID19 positive testing in high-risk individuals. Therapies include stand-alone or combination treatment with hydroxychloroquine, azithromycin, ivermectin, or camostat mesilate. The hypothesis of this study is that the addition of agents that inhibit viral entry or replication of SARS-CoV-2 virus, through alternative mechanisms to hydroxychloroquine, will be devoid of additional moderate to severe toxicities, will prevent clinical deterioration, and will improve viral clearance in high risk individuals.
