ritonavir and umifenovir

To systematically evaluate the efficacy and safety of arbidol and lopinavir/ritonavir (LPV/r) in the treatment of coronavirus disease 2019 (COVID-19) using a meta-analysis method.. The China Knowledge Network, VIP database, WanFang database PubMed database, Embase database, and Cochrane Library were searched for a collection of comparative studies on arbidol and lopinavir/ritonavir in the treatment of COVID-19. Meta-analysis was used to evaluate the efficacy and safety of Arbidol and lopinavir/ritonavir in the treatment of COVID-19.. The results of the systematic review indicated that Arbidol had a higher positive-to-negative conversion rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid on Day 7 (p = 0.03), a higher positive-to-negative conversion rate of SARS-CoV-2 nucleic acid on Day 14 (p = 0.006), a higher improvement rate of chest computed tomography on Day 14 (p = 0.02), a lower incidence of adverse reactions (p = 0.002) and lower rate of mortality (p = 0.007). There was no difference in the rate of cough disappearance on Day 14 (p = 0.24) or the rate of severe/critical illness (p = 0.07) between the two groups.. Arbidol may be superior to lopinavir/ritonavir in the treatment of COVID-19. However, due to the small number of included studies and the number of patients, high-quality multicenter large-sample randomized double-blind controlled trials are still needed for verification.

Because of the lack of vaccination, it is urgent to find effective antiviral agents for COVID-19 treatment.. Online databases were searched for articles published before or on 22 June 2020. Studies reporting the effectiveness and safety of antiviral agents for COVID-19 were analysed.. A total of 42 studies were included in this analysis. Hydroxychloroquine (HCQ) was not associated with the incidence of death (risk ratio (RR)=1.08; 95% CI 0.81 to 1.44) and severe cases (RR=1.05; 95% CI 0.61 to 1.81). Patients treated with HCQ obtained few benefits with respect to the clearance of viral RNA and were more likely to have adverse reactions. HCQ treatment could shorten the body temperature recovery time (weighted mean difference = -1.04; 95% CI -1.64 to -0.45). Lopinavir/ritonavir (LPV/r) (RR=0.90; 95% CI 0.76 to 1.07) and Arbidol (RR=1.09; 95% CI 0.92 to 1.29) were not associated with the negative conversion rate. Integrative Chinese-Western medicine alleviated clinical symptoms and decreased the incidence of severe cases (RR=0.38; 95% CI 0.25 to 0.59). Remdesivir treatment reduced the 14-day mortality rate of patients with severe COVID-19 (RR=0.64; 95% CI 0.44 to 0.94). Convalescent plasma (CP) tended to increase the negative conversion rate (RR=2.47; 95% CI 1.70 to 3.57).. HCQ, LPV/r and Arbidol bring little benefit in COVID-19 treatment. Integrative Chinese-Western medicine improved the clinical symptoms of patients with COVID-19. Remdesivir and CP might be the potential treatments for patients with severe COVID-19. However, large-scale clinical randomised trials are needed to validate our conclusions.

The ongoing SARS-CoV-2 pandemic stresses the need for effective antiviral drugs that can quickly be applied in order to reduce morbidity, mortality, and ideally viral transmission. By repurposing of broadly active antiviral drugs and compounds that are known to inhibit viral replication of related viruses, several advances could be made in the development of treatment strategies against COVID-19. The nucleoside analog remdesivir, which is known for its potent in vitro activity against Ebolavirus and other RNA viruses, was recently shown to reduce the time to recovery in patients with severe COVID-19. It is to date the only approved antiviral for treating COVID-19. Here, we provide a mechanism and evidence-based comparative review of remdesivir and other repurposed drugs with proven in vitro activity against SARS-CoV-2.

We are living through an unprecedented crisis with the rapid spread of the new coronavirus disease (COVID-19) worldwide within a short time. The timely availability of thousands of SARS-CoV-2 genomes has enabled the scientific community to study the origin, structures, and pathogenesis of the virus. The pandemic has spurred research publication and resulted in an unprecedented number of therapeutic proposals. Because the development of new drugs is time consuming, several strategies, including drug repurposing and repositioning, are being tested to treat patients with COVID-19. Researchers have developed several potential vaccine candidates that have shown promise in phase II and III trials. As of 12 November 2020, 164 candidate vaccines are in preclinical evaluation, and 48 vaccines are in clinical evaluation, of which four have cleared phase III trials (Pfizer/BioNTech's BNT162b2, Moderna's mRNA-1273, University of Oxford & AstraZeneca's AZD1222, and Gamaleya's Sputnik V vaccine). Despite the acquisition of a vast body of scientific information, treatment depends only on the clinical management of the disease through supportive care. At the pandemic's 1-year mark, we summarize current information on SARS-CoV-2 origin and biology, and advances in the development of therapeutics. The updated information presented here provides a comprehensive report on the scientific progress made in the past year in understanding of SARS-CoV-2 biology and therapeutics.

The whole world is battling through coronavirus disease 2019 (COVID-19) which is a fatal pandemic. In the early 2020, the World Health Organization (WHO) declared it as a global health emergency without definitive treatments and preventive approaches. In the absence of definitive therapeutic agents, this thorough review summarizes and outlines the potency and safety of all molecules and therapeutics which may have potential antiviral effects. A number of molecules and therapeutics licensed or being tested for some other conditions were found effective in different in vitro studies as well as in many small sample-sized clinical trials and independent case studies. However, in those clinical trials, there were some limitations which need to be overcome to find the most promising antiviral against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In conclusion, many of above-mentioned antivirals seems to have some therapeutic effects but none of them have been shown to have a strong evidence for their proper recommendation and approval in the treatment of COVID-19. Constantly evolving new evidences, exclusive adult data, language barrier, and type of study (observational, retrospective, small-sized clinical trials, or independent case series) resulted to the several limitations of this review. The need for multicentered, large sample-sized, randomized, placebo-controlled trials on COVID-19 patients to reach a proper conclusion on the most promising antiviral agent is warranted.

Despite aggressive efforts on containment measures for the coronavirus disease 2019 (COVID-19) pandemic around the world, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is continuously spreading. Therefore, there is an urgent need for an effective antiviral agent. To date, considerable research has been conducted to develop different approaches to COVID-19 therapy. In addition to early observational studies, which could be limited by study design, small sample size, non-randomized design, or different timings of treatment, an increasing number of randomized controlled trials (RCTs) investigating the clinical efficacy and safety of antiviral agents are being carried out. This study reviews the updated findings of RCTs regarding the clinical efficacy of eight antiviral agents against COVID-19, including remdesivir, lopinavir/ritonavir, favipiravir, sofosbuvir/daclatasvir, sofosbuvir/ledipasvir, baloxavir, umifenovir, darunavir/cobicistat, and their combinations. Treatment with remdesivir could accelerate clinical improvement; however, it lacked additional survival benefits. Moreover, 5-day regimen of remdesivir might show adequate effectiveness in patients with mild to moderate COVID-19. Favipiravir was only marginally effective regarding clinical improvement and virological assessment based on the results of small RCTs. The present evidence suggests that sofosbuvir/daclatasvir may improve survival and clinical outcomes in patients with COVID-19. However, the sample sizes for analysis were relatively small, and all studies were exclusively conducted in Iran. Further larger RCTs in other countries are warranted to support these findings. In contrast, the present findings of limited RCTs did not indicate the use of lopinavir/ritonavir, sofosbuvir/ledipasvir, baloxavir, umifenovir, and darunavir/cobicistat in the treatment of patients hospitalized for COVID-19.

The effectiveness of umifenovir against COVID-19 is controversial; therefore, clinical trials are crucial to evaluate its efficacy.. The study was conducted as a single-center, randomized, open-label clinical trial. Eligible moderate-severe hospitalized patients with confirmed SARS-Cov-2 infection were randomly segregated into intervention and control groups. The intervention group were treated with lopinavir/ritonavir (400 mg/100 mg bid for 10-14 days) + hydroxychloroquine (400 mg single dose) + interferon-β1a (Subcutaneous injections of 44 µg (12,000 IU) on days 1, 3, 5) + umifenovir (200 mg trice daily for 10 days), and the control group received lopinavir/ritonavir (same dose) + hydroxychloroquine (same dose) + interferon-β1a (same dose).. Of 1180 patients with positive RT-PCRs and positive chest CT scans, 101 patients were finally included in the trial; 50 were assigned to receive IFNβ1a + hydroxychloroquine + lopinavir/ritonavir group and 51 were managed to treat with IFNβ1a + hydroxychloroquine + lopinavir/ritonavir + umifenovir. Since all patients received the intended treatment as scheduled, the analysis just included as the ITT population. Time to clinical improvement (TTCI) did not hold a statistically significant difference between intervention and control groups (median, 9 days for intervention group versus 7 days for the control group; P: 0.22). Besides, Hazard Ratio for TTCI in the Cox regression model was 0.75 (95% CI: 0.45-1.23, P:0.25) which also confirmed that there was no statistically significant difference between the treatment group and the control group. The mortality was not statistically significant between the two groups (38% in controls vs 33.3% treatment group).. Our findings shed new lights on the facts that additional umifenovir has not been found to be effective in shortening the duration of SARS-CoV-2 in severe patients and improving the prognosis in non-ICU patients and mortality.. The trial was confirmed by the Ethics in Medical Research Committee of the Shahid Beheshti University of Medical Sciences. signed informed consents were obtained from all the participants or their legally authorized representatives. This trial has been registered as ClinicalTrials.gov, NCT04350684.

The pandemic of coronavirus disease 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) presents an unprecedented challenge to identify effective drugs for prevention and treatment. Given the rapid pace of scientific discovery and clinical data generated by the large number of people rapidly infected by SARS-CoV-2, clinicians need accurate evidence regarding effective medical treatments for this infection.. No proven effective therapies for this virus currently exist. The rapidly expanding knowledge regarding SARS-CoV-2 virology provides a significant number of potential drug targets. The most promising therapy is remdesivir. Remdesivir has potent in vitro activity against SARS-CoV-2, but it is not US Food and Drug Administration approved and currently is being tested in ongoing randomized trials. Oseltamivir has not been shown to have efficacy, and corticosteroids are currently not recommended. Current clinical evidence does not support stopping angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in patients with COVID-19.. The COVID-19 pandemic represents the greatest global public health crisis of this generation and, potentially, since the pandemic influenza outbreak of 1918. The speed and volume of clinical trials launched to investigate potential therapies for COVID-19 highlight both the need and capability to produce high-quality evidence even in the middle of a pandemic. No therapies have been shown effective to date.

The virus severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is currently affecting more than 200 countries and territories worldwide. It has been declared as pandemic by World Health Organization (WHO) and the whole world is suffering from corona virus disease 2019 (COVID-19). Currently, no treatment for SARS-CoV-2 are approved because of lack of evidence, but a number of clinical trials are in process and we are expecting fruitful results very soon. This review focuses on various approaches of treatment and few of the most recent clinical trials carried out in this field.

Antiviral medications are being given empirically to some patients with coronavirus disease 2019 (COVID-19). To support the development of a COVID-19 management guideline, we conducted a systematic review that addressed the benefits and harms of 7 antiviral treatments for COVID-19.. We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed and 3 Chinese databases (CNKI, WANFANG and SinoMed) through Apr. 19, medRxiv and Chinaxiv through Apr. 27, and Chongqing VIP through Apr. 30, 2020. We included studies of ribavirin, chloroquine, hydroxychloroquine, umifenovir (arbidol), favipravir, interferon and lopinavir/ritonavir. If direct evidence from COVID-19 studies was not available, we included indirect evidence from studies of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) for efficacy outcomes and other acute respiratory viral infections for safety outcomes.. In patients with nonsevere COVID-19 illness, the death rate was extremely low, precluding an important effect on mortality. We found only very low-quality evidence with little or no suggestion of benefit for most treatments and outcomes in both nonsevere and severe COVID-19. An exception was treatment with lopinavir/ritonavir, for which we found low-quality evidence for a decrease in length of stay in the intensive care unit (risk difference 5 d shorter, 95% confidence interval [CI] 0 to 9 d) and hospital stay (risk difference 1 d shorter, 95% CI 0 to 2 d). For safety outcomes, evidence was of low or very low quality, with the exception of treatment with lopinavir/ritonavir for which moderate-quality evidence suggested likely increases in diarrhea, nausea and vomiting.. To date, persuasive evidence of important benefit in COVID-19 does not exist for any antiviral treatments, although for each treatment evidence has not excluded important benefit. Additional randomized controlled trials involving patients with COVID-19 will be needed before such treatments can be administered with confidence.

Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), initially termed 2019-new CoV (2019-nCoV), is a novel coronavirus responsible for the severe respiratory illness currently ongoing worldwide from the beginning of December 2019. This beta gene virus, very close to bat coronaviruses (bat-CoV-RaTG13) and bat-SL-CoVZC45, causes a severe disease, similar to those caused by Middle East respiratory syndrome (MERS)-CoV and SARS-CoV viruses, featured by low to moderate mortality rate. Unfortunately, the antiviral drugs commonly used in clinical practice to treat viral infections, are not applicable to SARS-Cov-2 and no vaccine is available. Thus, it is extremely necessary to identify new drugs suitable for the treatment of the 2019-nCoV outbreak. Different preclinical studies conducted on other coronaviruses suggested that promising clinical outcomes for 2019-nCoV should be obtained by using alpha-interferon, chloroquine phosphate, arabinol, remdesivir, lopinavir/ritonavir, and anti-inflammatory drugs. Moreover, clinical trials with these suitable drugs should be performed on patients affected by SARS-Cov-2 to prove their efficacy and safety. Finally, a very promising therapeutic drug, tocilizumab, is discussed; it is currently used to treat patients presenting COVID-19 pneumonia. Herein, we recapitulate these experimental studies to highlight the use of antiviral drugs for the treatment of SARS-Cov-2 disease.

The fight against the novel coronavirus pneumonia (namely COVID-19) that seriously harms human health is a common task for all mankind. Currently, development of drugs against the novel coronavirus (namely SARS-CoV-2) is quite urgent. Chinese medical workers and scientific researchers have found some drugs to play potential therapeutic effects on COVID-19 at the cellular level or in preliminary clinical trials. However, more fundamental studies and large sample clinical trials need to be done to ensure the efficacy and safety of these drugs. The adoption of these drugs without further testing must be careful. The relevant articles, news, and government reports published on the official and Preprint websites, PubMed and China National Knowledge Infrastructure (CNKI) databases from December 2019 to April 2020 were searched and manually filtered. The general pharmacological characteristics, indications, adverse reactions, general usage, and especially current status of the treatment of COVID-19 of those potentially effective drugs, including chemical drugs, traditional Chinese medicines (TCMs), and biological products in China were summarized in this review to guide reasonable medication and the development of specific drugs for the treatment of COVID-19.

The Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly become a global pandemic. Up to now, numerous medicines have been applied or approved for the prevention and control of the virus infection. However, the efficiency of each medicine or combination is completely different or still unknown. In this review, we discuss the types, characteristics, antiviral mechanisms, and shortcomings of recommended candidate medicines for SARS-CoV-2 infection, as well as perspectives of the drugs for the disease treatment, which may provide a theoretical basis for drug screening and application.

SARS-CoV-2 has caused a pandemic which is putting strain on the health-care system and global economy. There is much pressure to develop both preventative and curative therapies for SARS-CoV-2 as there is no evidence to support therapies to improve outcomes in patients with SARS-CoV-2. Medications that inhibit certain steps of virus life cycle that are currently used to treat other illnesses such as Malaria, Ebola, HIV and Hepatitis C are being studied for use against SARS-CoV-2. To date, data is limited for medications that facilitate clinical improvement of COVID-19 infections.

Since a novel coronavirus pneumonia outbreak in late December 2019, coronavirus disease -19 (COVID-19) epidemic has gradually spread worldwide, becoming a major public health event. No specific antivirals are currently available for COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The treatments for COVID-19 are mainly based on the experiences of similar virus such SARS-CoV, MERS-CoV, HIV and influenza viruses. Scientists have taken great efforts to investigate the effective methods for the treatment of COVID-19. Up to now, there are over 1000 clinical studies for COVID-19 all over the world. In this article, we reviewed the current options for COVID-19 therapy including small molecules such as Remdesivir, Favipiravir, Lopinavir/Ritonavir etc, peptide inhibitors of ACE2, Traditional Chinese Medicines and Biologics such as SARS-CoV-2-specific neutralizing antibodies, mesenchymal stem cells and vaccines etc. Meanwhile, we systematically reviewed their clinical safety, clinical applications and progress of antiviral researches. The therapeutic effect of these antiviral drugs is summarized and compared, hoping to provide some ideas for clinical options of COVID-19 treatment and also provide experiences for the life-threatening virus diseases in the future.

The unprecedented challenge faced by mankind due to emergence of coronavirus 2019 (COVID-19) pandemic has obligated researchers across the globe to develop effective medicine for prevention and treatment of this deadly infection. The aim of this review is to compile recently published research articles on anti-COVID 19 management with their benefits and risk to facilitate decision making of the practitioners and policy makers. Unfortunately, clinical outcomes reported for antivirals are not consistent. Initial favorable reports on lopinavir/ritonavir contradicted by recent studies. Ostalmovir has conflicting reports. Short term therapy of remdesivir claimed to be beneficial. Favipiravir demonstrated good recovery in some of the cases of COVID-19. Umifenovir (Arbidol) was associated with reduction in mortality in few studies. Overall, until now, U.S. Food and Drug administration issued only emergency use authorization to remdesivir for the treatment of suspected or laboratory-confirmed COVID-19 in adults and children hospitalized with severe disease.

Coronavirus disease 2019, also known as COVID-19, is caused by a novel coronavirus named severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2. The infection has now catapulted into a full-blown pandemic across the world, which has affected more than 2 million people and has led to approximately 150,000 fatalities all over the world (WHO). In this review, we elaborate all currently available data that shed light on possible methods for treatment of COVID-19, such as antiviral drugs, corticosteroids, convalescent plasma, and potentially effective vaccines. Additionally, ongoing and discontinued clinical trials that have been carried out for validating probable treatments for COVID-19 are discussed. The review also elaborates the prospective approach and the possible advantages of using convalescent plasma and stem cells for the improvement of clinical symptoms and meeting the demand for an instantaneous cure.

In December 2019, a novel coronavirus SARS-CoV-2, causing the disease COVID-19, spread from Wuhan throughout China and has infected people over 200 countries. Thus far, more than 3,400,000 cases and 240,000 deaths have occurred worldwide, and the coronavirus pandemic continues to grip the globe. While numbers of cases in China have been steadying, the number of infections outside China is increasing at a worrying pace. We face an urgent need to control the spread of the COVID-19 epidemic, which is currently expanding to a global pandemic. Efforts have focused on testing antiviral drugs and vaccines, but there is currently no treatment specifically approved. Traditional Chinese medicine (TCM) is grounded in empirical observations and the Chinese people use TCM to overcome these sorts of plagues many times in thousands of years of history. Currently, the Chinese National Health Commission recommended a TCM prescription of Qing-Fei-Pai-Du-Tang (QFPDT) in the latest version of the "Diagnosis and Treatment guidelines of COVID-19" which has been reported to provide reliable effects for COVID-19. While doubts about TCM still exist today, this review paper will describe the rationalities that QFPDT is likely to bring a safe and effective treatment of COVID-19.

The coronavirus disease 2019 (COVID-19) is declared as an international emergency in 2020. Its prevalence and fatality rate are rapidly increasing but the medication options are still limited for this perilous disease. The emergent outbreak of COVID-19 triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) keeps propagating globally. The present scenario has emphasized the requirement for therapeutic opportunities to relive and overcome this latest pandemic. Despite the fact, the deteriorating developments of COVID-19, there is no drug certified to have considerable effects in the medical treatment for COVID-19 patients. The COVID-19 pandemic requests for the rapid testing of new treatment approaches. Based on the evidence, hydroxychloroquine is the first medicine opted for the treatment of disease. Umifenovir, remdesivir, and fevipiravir are deemed the most hopeful antiviral agent by improving the health of infected patients. The dexamethasone is a first known steroid medicine that can save the lives of seriously ill patients, and it is shown in a randomized clinical trial by the United Kingdom that it reduced the death rate in COVID-19 patients. The current review recapitulates the existing evidence of possible therapeutic drugs, peptides, humanized antibodies, convulsant plasma, and vaccination that has revealed potential in fighting COVID-19 infections. Many randomized and controlled clinical trials are taking place to further validate these agent's safety and effectiveness in curing COVID-19.

Shufeng Jiedu capsules (SFJDC), a patented herbal drug composed of eight medicinal plants, is used for the treatment of different viral respiratory tract infectious diseases. Based on its antiviral, anti-inflammatory and immunoregulatory activity in acute lung injury, SFJDC might be a promising candidate for the treatment of COVID-19.. To evaluate the antiviral and anti-inflammatory properties and to discover the mechanism of action of SFJDC as a potential drug for the treatment of COVID-19. Furthermore, the study should determine the clinical effectiveness of SFJDC for the treatment of COVID-19.. We analyzed the antiviral and anti-inflammatory effects of SFJDC in a HCoV-229E mouse model on lung index, virus load in the lung, the release of cytokines, and on T- and B-lymphocytes. The mechanism of action was further investigated by network analysis. Additionally, we investigated data from a clinical pragmatic real-world study for patients with confirmed COVID-19, to evaluate the clinical effect of SFJDC and to determine the best time to start the treatment.. SFJDC significantly reduced the virus load in the lung of HCoV-229E mice (from 1109.29 ± 696.75 to 0 ± 0 copies/ml), decreased inflammatory factors IL-6, IL-10, TNF-α, and IFN-γ in the lung, and increased the amount of CD4. SFJDC might be a promising drug for the treatment of COVID-19, but large-scale randomized, double-blinded, placebo-controlled clinical trials are needed to complement the real-world evidence. It might be beneficial to start SFJDC treatment as early as possible in suspected cases of COVID-19.

Antiviral therapies against the novel coronavirus SARS-CoV-2, which has caused a global pandemic of respiratory illness called COVID-19, are still lacking.. Our study (ClinicalTrials.gov: NCT04252885, named ELACOI), was an exploratory randomized (2:2:1) controlled trial assessing the efficacy and safety of lopinavir/ritonavir (LPV/r) or arbidol monotherapy for treating patients with mild/moderate COVID-19.. This study successfully enrolled 86 patients with mild/moderate COVID-19, with 34 randomly assigned to receive LPV/r, 35 to arbidol, and 17 with no antiviral medication as control. Baseline characteristics of the three groups were comparable. The primary endpoint, the rate of positive-to-negative conversion of SARS-CoV-2 nucleic acid, was similar between groups (all p > 0.05). There were no differences between groups in the secondary endpoints, the rates of antipyresis, cough alleviation, or improvement of chest computed tomography (CT) at days 7 or 14 (all p > 0.05). At day 7, 8 (23.5%) patients in the LPV/r group, 3 (8.6%) in the arbidol group, and 2 (11.8%) in the control group showed a deterioration in clinical status from moderate to severe/critical (p = 0.206). Overall, 12 (35.3%) patients in the LPV/r group and 5 (14.3%) in the arbidol group experienced adverse events during the follow-up period. No apparent adverse event occurred in the control group.. LPV/r or arbidol monotherapy present little benefit for improving the clinical outcome of patients hospitalized with mild/moderate COVID-19 over supportive care.. This study was supported by project 2018ZX10302103-002, 2017ZX10202102-003-004, and Infectious Disease Specialty of Guangzhou High-level Clinical Key Specialty (2019-2021).

A severe epidemic of COVID-19 has broken out in China and has become a major global public health event. We focus on the Acute Respiratory Distress Syndrome (ARDS)-like changes and overactivation of Th17 cells (these produce cytokines) in patients with COVID-19. We aim to explore the safety and efficacy of ixekizumab (an injectable drug for the treatment of autoimmune diseases) to prevent organ injury caused by the immune response to COVID-19. Ixekizumab is a human monoclonal antibody that binds to interleukin-17A and inhibits the release of pro-inflammatory cytokines and chemokines.. The experiment is divided into two stages. In the first stage, the open trial, 3 patients with COVID-19 are treated with ixekizumab, and the safety and efficacy are observed for 7 days. In the second stage, 40 patients with COVID-19 are randomly divided into two groups at 1:1 for 14 days. This is a two-center, open-label, randomized controlled pilot trial with 2-arm parallel group design (1:1 ratio).. Patients with COVID-19 aged 18-75 with increased Interleukin (IL)-6 levels will be enrolled, but patients with severe infections requiring intensive care will be excluded. The trial will be undertaken in two centers. The first stage is carried out in Xiangya Hospital of Central South University, and the second stage is carried out simultaneously in the Third Xiangya Hospital of Central South University.. In the first stage, three subjects are given ixekizumab ("Taltz") (80 mg/ml, 160 mg as a single hypodermic injection) and antiviral therapy (α-interferon (administer 5 million U by aerosol inhalation twice daily), lopinavir/ritonavir (administer 100mg by mouth twice daily, for the course of therapy no more than 10 days), chloroquine (administer 500mg by mouth twice daily, for the course of therapy no more than 10 days), ribavirin (administer 500mg by intravenous injection two to three times a day, for the course of therapy no more than 10 days), or arbidol (administer 200mg by mouth three times a day, for the course of therapy no more than 10 days), but not more than 3 types). The treatment course of the first stage is 7 days. In the second stage, 40 randomized patients will receive the following treatments--Group 1: ixekizumab (80 mg/ml, 160 mg as a single hypodermic injection) with antiviral therapy (the same scheme as in the first stage); Group 2: antiviral therapy alone (the same scheme as in the first stage). The length of the second treatment course is 14 days.. The primary outcome is a change in pulmonary CT severity score (an imaging tool for assessing COVID-19, which scores on the basis of all abnormal areas involved). Pulmonary CT severity score is assessed on the 7th day, 14th day, or at discharge.. In the second stage, 40 patients with COVID-19 are randomly divided into two groups at 1:1 for 14 days. The eLite random system of Nanjing Medical University is used for randomization.. The main efficacy indicator, the CT results, will be evaluated by the third-party blinded and independent research team.. In the second stage, 40 patients with COVID-19 are randomly divided into two groups at 1:1 for 14 days.. Trial registration number is ChiCTR2000030703 (version 1.7 as of March 19, 2020). The recruitment is ongoing, and the date recruitment was initiated in June 2020. The anticipated date of the end of data collection is June 2021.. The name of the trial register is the Chinese Clinical Trial Registry. The trial registration number is ChiCTR2000030703 ( http://www.chictr.org.cn/ ). The date of trial registration is 10 March 2020.. The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1).

Treatment of patients with COVID-19 has included supportive care to mainly relief symptoms of the disease. Although World Health Organization (WHO) has not recommended any effective treatments for COVID-19, there are some reports about use of antiviral drugs. The aim of this study is to determine the effect of Arbidol (ARB) on COVID-19 disease.. Using an open-label randomized controlled trial, we examined the efficacy of ARB in patients with COVID-19 in a teaching hospital. One hundred eligible patients with diagnosis of COVID-19 were recruited in the study and assigned randomly to two groups of either hydroxychloroquine followed by KALETRA (Lopinavir/ritonavir) or hydroxychloroquine followed by ARB. The primary outcome was hospitalization duration and clinical improvement 7 days after admission. The criteria of improvement were relief of cough, dyspnea, and fever. Time to relief from fever was also assessed across the two groups. Without any dropouts, 100 patients were entered into the study for the final analysis at significance level of 0.05.. The mean age of patients was 56.6 (17.8) years and 56.2 (14.8) years in ARB and KALETRA groups, respectively. Majority of patients were male across two groups (66 and 54%). The duration of hospitalization in ARB group was significantly less than KALETRA arm (7.2 versus 9.6 days; P = 0.02). Time to relief fever was almost similar across two groups (2.7 versus 3.1 days in ARB and KALETRA arms, respectively). Peripheral oxygen saturation rate was significantly different after 7 days of admission across two groups (94% versus 92% in ARB and KALETRA groups respectively) (P = 0.02). Based on multiple linear regression analysis, IHD, Na level, and oxygen saturation at the time of admission and type of therapy were the independent adjusted variables that determined the duration of hospitalization in patients with COVID-19.. Our findings showed that Arbidol, compared to KALETRA, significantly contributes to clinical and laboratory improvements, including peripheral oxygen saturation, requiring ICU admissions, duration of hospitalization, chest CT involvements, WBC, and ESR. We suggest further studies on ARB against COVID-19 using larger sample size and multicenter design.. IRCT20180725040596N2 on 18 April 2020.

Coronavirus disease 19 (COVID-19) has posed serious threats to the general population. To relieve the crisis, a comparison of drug effects against COVID-19 is instructive. Between January 27, 2020 and March 21, 2020, a total of 333 patients treated with arbidol, corticosteroids, hydroxychloroquine, lopinavir/ritonavir, or oseltamivir monotherapy, having definite outcomes and serological antibody detection results, were retrospectively analyzed. The hydroxychloroquine group had a significantly reduced duration of hospital stay than the arbidol and corticosteroids groups. The oseltamivir group had a significantly shorter length of hospital stay than the arbidol, corticosteroids, and lopinavir/ritonavir groups. The hydroxychloroquine group had a significantly higher IgM titer than the other four groups and exhibited significantly higher IgG levels than the arbidol, lopinavir/ritonavir, and oseltamivir groups. Our findings indicated that hydroxychloroquine might have the potential for efficient COVID-19 management, while oseltamivir should be prudently considered in combination therapy.

This study aims to comparatively analyze the therapeutic efficacy upon multiple medication plans over lopinavir/ritonavir (LPV/r), arbidol (ARB), and methylprednisolone on patients with coronavirus disease 2019 (COVID-19). Totally, 75 COVID-19 patients admitted to The First Affiliated Hospital, Zhejiang University School of Medicine from January 22, 2020 to February 29, 2020 were recruited and grouped based on whether or not LPV/r and ARB were jointly used and whether or not methylprednisolone was used. Indexes including body temperature, time for nucleic acid negative conversion, hospital stays, and laboratory indexes were examined and compared. For all patients, there were no significant differences in the change of body temperature, the time for negative conversion, and hospital stays whether LPV/r and ARB were jointly used or not. While for severe and critically severe patients, methylprednisolone noticeably reduced the time for negative conversion. Meanwhile, the clinical efficacy was superior on patients receiving methylprednisolone within 3 days upon admission, and the duration of hospital stays was much shorter when methylprednisolone was given at a total dose of 0-400 mg than a higher dose of >400 mg if all patients received a similar dose per day. Nonetheless, no significant changes across hepatic, renal, and myocardial function indexes were observed. LPV/r combined with ARB produced no noticeably better effect on COVID-19 patients relative to the single-agent treatment. Additionally, methylprednisolone was efficient in severe and critically severe cases, and superior efficacy could be realized upon its early, appropriate, and short-term application.

Coronavirus disease 2019 (COVID-19) is an emerging disease caused by severe acute respiratory syndrome coronavirus 2; no specific effective medication to treat the disease has been identified to date. We aimed to investigate the administered medications and intervention times for patients who completely recovered from COVID-19.This single-center, retrospective, observational study included 55 patients with COVID-19 who were transferred to Shenyang Sixth People's Hospital between January 20 and March 15, 2020. Data on demographics, symptoms, laboratory indicators, treatment processes, and clinical outcomes were collected. Administered drugs and intervention times were compared in 47 and 8 patients with mild and severe symptoms, respectively.All 55 patients recovered. Fifty-three patients (96.36%) received antiviral therapy, including 45 in the mild group (median treatment: 14 days; 17 received umifenovir) and all 8 severe-group patients (median treatment: 17.5 days; 4 received lopinavir/ritonavir). Twenty-nine patients (52.72%) were administered antibiotics, including 21 in the mild group (median treatment: 13.5 days; 15 received moxifloxacin) and all 8 in the severe group (median treatment: 9 days; 2 received linezolid). Moreover, 7 patients (12.72%) were treated with glucocorticoids and 9 (16.36%) with immunomodulators.Given the 100% recovery rate, early administration of antiviral drugs can be considered. Umifenovir may benefit patients with mild symptoms, while lopinavir/ritonavir may benefit those with severe symptoms. Prophylactic administration of common antibiotics may reduce the risk of co-infection. The use of glucocorticoids is usually not necessary. Randomized, double-blind, and controlled trials remain necessary for more accurate conclusions.

This study aimed to evaluate the antiviral efficacy of lopinavir-ritonavir alone or combined with arbidol in the treatment of hospitalized patients with common coronavirus disease-19 (COVID-19).. In this retrospective observational study, hospitalized COVID-19 patients were identified and divided into two groups based on the antiviral agents during their hospitalization. Patients in group LR were treated with lopinavir-ritonavir 400 mg/100 mg, twice a day, while patients in group LR+Ar were treated with lopinavir-ritonavir 400 mg/100 mg twice a day and arbidol 200 mg three times a day for at least 3 days. Data from these patients were collected from electronic medical record management system.. 73 patients were divided into two groups: group LR (34 cases) and group LR+Ar (39 cases), according to the antiviral agents. The overall cure rate of COVID-19 in group LR+Ar and group LR were 92.3% and 97.1%, respectively, with no significant difference (p = 0.62). In a modified intention-to-treat analysis, lopinavir-ritonavir combined with arbidol led to a median time of hospital stay that was shorter by 1.5 days than in group LR (12.5 days vs. 14 days). The percentages of -COVID-19 RNA clearance was 92.3 in group LR and 97.1 in group LR+Ar which was similar to the cure rate. The median time to nucleic acid turning negative = (date of first negative PCR test) - (date of last positive PCR test) was 8.0 days in both groups with no significant difference (p = 0.59). Treatment of lopinavir-ritonavir combined with arbidol did not significantly accelerate main symptom improvement and promote the image absorption of pulmonary inflammation.. No benefit was observed in the antiviral effect of lopinavir-ritonavir combined with arbidol compared with lopinavir-ritonavir alone in the hospitalized patients with COVID-19. More clinical observations in COVID-19 patients may help to confirm or exclude the effect of antiviral agents.

The coronavirus disease 2019 (COVID-19) emerged around December 2019 and have become a global epidemic disease currently. Specific antibodies against SAS-COV-2 could be detected in COVID-19 patients' serum or plasma, but the clinical values of these antibodies as well as the effects of clinical drugs on humoral responses have not been fully demonstrated. In this study, 112 plasma samples were collected from 36 patients diagnosed with laboratory-confirmed COVID-19 in the Fifth Affiliated Hospital of Sun Yat-sen University. The IgG and IgM antibodies against receptor binding domain (RBD) and spike protein subunit 1 (S1) of SAS-COV-2 were detected by ELISA. We found that COVID-19 patients generated specific antibodies against SARS-CoV-2 after infection, and the levels of anti-RBD IgG within 2 to 3 weeks from onset were negatively associated with the time of positive-to-negative conversion of SARS-CoV-2 nucleic acid. Patients with severe symptoms had higher levels of anti-RBD IgG in 2 to 3 weeks from onset. The use of chloroquine did not significantly influence the patients' antibody titer but reduced C-reaction protein (CRP) level. Using anti-viral drugs (lopinavir/ritonavir or arbidol) reduced antibody titer and peripheral lymphocyte count. While glucocorticoid therapy developed lower levels of peripheral lymphocyte count and higher levels of CRP, lactate dehydrogenase (LDH), α-Hydroxybutyrate dehydrogenase(α-HBDH), total bilirubin (TBIL), direct bilirubin (DBIL). From these results, we suggested that the anti-RBD IgG may provide an early protection of host humoral responses against SAS-COV-2 infection within 2 to 3 weeks from onset, and clinical treatment with different drugs displayed distinct roles in humoral and inflammatory responses.

Corrected QT (QTc) interval prolongation has been associated with poor patient prognosis. In this study, we assessed the effects of different drugs and cardiac injury on QTc interval prolongation in patients with coronavirus disease 2019 (COVID-19).The study cohort consisted of 395 confirmed COVID-19 cases from the Wuhan Union Hospital West Campus. All hospitalized patients were treated with chloroquine/hydroxychloroquine (CQ/HCQ), lopinavir/ritonavir (LPV/r), quinolones, interferon, Arbidol, or Qingfei Paidu decoction (QPD) and received at least 1 electrocardiogram after drug administration.Fifty one (12.9%) patients exhibited QTc prolongation (QTc ≥ 470 ms). QTc interval prolongation was associated with COVID-19 severity and mortality (both P < .001). Administration of CQ/HCQ (odds ratio [OR], 2.759; 95% confidence interval [CI], 1.318-5.775; P = .007), LPV/r (OR, 2.342; 95% CI, 1.152-4.760; P = .019), and quinolones (OR, 2.268; 95% CI, 1.171-4.392; P = .015) increased the risk of QTc prolongation. In contrast, the administration of Arbidol, interferon, or QPD did not increase the risk of QTc prolongation. Notably, patients treated with QPD had a shorter QTc duration than those without QPD treatment (412.10 [384.39-433.77] vs 420.86 [388.19-459.58]; P = .042). The QTc interval was positively correlated with the levels of cardiac biomarkers (creatine kinase-MB fraction [rho = 0.14, P = .016], high-sensitivity troponin I [rho = .22, P < .001], and B-type natriuretic peptide [rho = 0.27, P < .001]).In conclusion, QTc prolongation was associated with COVID-19 severity and mortality. The risk of QTc prolongation was higher in patients receiving CQ/HCQ, LPV/r, and quinolones. QPD had less significant effects on QTc prolongation than other antiviral agents.

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has occasioned worldwide alarm. Globally, the number of reported confirmed cases has exceeded 84.3 million as of this writing (January 2, 2021). Since there are no targeted therapies for COVID-19, the current focus is the repurposing of drugs approved for other uses. In some clinical trials, antiviral drugs such as remdesivir (Grein et al., 2020), lopinavir/ritonavir (LPV/r) (Cao et al., 2020), chloroquine (Gao et al., 2020), hydroxychloroquine (Gautret et al., 2020), arbidol (Wang et al., 2020), and favipiravir (Cai et al., 2020b) have shown efficacy in COVID-19 patients. LPV/r combined with arbidol, which is the basic regimen in some regional hospitals in China including Zhejiiang Province, has shown antiviral effects in COVID-19 patients (Guo et al., 2020; Xu et al., 2020). A retrospective cohort study also reported that this combination therapy showed better efficacy than LPV/r alone for the treatment of COVID-19 patients (Deng et al., 2020).

Corona Virus Disease 2019 (COVID-19) due to the 2019 novel coronavirus (SARS-CoV-2) emerged in Wuhan city and rapidly spread throughout China. We aimed to compare arbidol and lopinavir/ritonavir(LPV/r) treatment for patients with COVID-19 with LPV/r only.. In this retrospective cohort study, we included adults (age≥18years) with laboratory-confirmed COVID-19 without Invasive ventilation, diagnosed between Jan 17, 2020, and Feb 13, 2020. Patients, diagnosed after Jan 17, 2020, were given oral arbidol and LPV/r in the combination group and oral LPV/r only in the monotherapy group for 5-21 days. The primary endpoint was a negative conversion rate of coronavirus from the date of COVID-19 diagnosis(day7, day14), and assessed whether the pneumonia was progressing or improving by chest CT (day7).. We analyzed 16 patients who received oral arbidol and LPV/r in the combination group and 17 who oral LPV/r only in the monotherapy group, and both initiated after diagnosis. Baseline clinical, laboratory, and chest CT characteristics were similar between groups. The SARS-CoV-2 could not be detected for 12(75%) of 16 patients' nasopharyngeal specimens in the combination group after seven days, compared with 6 (35%) of 17 in the monotherapy group (p < 0·05). After 14 days, 15 (94%) of 16 and 9 (52·9%) of 17, respectively, SARS-CoV-2 could not be detected (p < 0·05). The chest CT scans were improving for 11(69%) of 16 patients in the combination group after seven days, compared with 5(29%) of 17 in the monotherapy group (p < 0·05).. In patients with COVID-19, the apparent favorable clinical response with arbidol and LPV/r supports further LPV/r only.

Lopinavir/ritonavir and arbidol have been previously used to treat acute respiratory syndrome- coronavirus 2 (SARS-CoV-2) replication in clinical practice; nevertheless, their effectiveness remains controversial. In this study, we evaluated the antiviral effects and safety of lopinavir/ritonavir and arbidol in patients with the 2019-nCoV disease (COVID-19). Fifty patients with laboratory-confirmed COVID-19 were divided into two groups: including lopinavir/ritonavir group (34 cases) and arbidol group (16 cases). Lopinavir/ritonavir group received 400 mg/100mg of Lopinavir/ritonavir, twice a day for a week, while the arbidol group was given 0.2 g arbidol, three times a day. Data from these patients were retrospectively analyzed. The cycle threshold values of open reading frame 1ab and nucleocapsid genes by RT-PCR assay were monitored during antiviral therapy. None of the patients developed severe pneumonia or ARDS. There was no difference in fever duration between the two groups (P=0.61). On day 14 after the admission, no viral load was detected in arbidol group, but the viral load was found in 15(44.1%) patients treated with lopinavir/ritonavir. Patients in the arbidol group had a shorter duration of positive RNA test compared to those in the lopinavir/ritonavir group (P<0.01). Moreover, no apparent side effects were found in both groups. In conclusion, our data indicate that arbidol monotherapy may be superior to lopinavir/ritonavir in treating COVID-19.

Here we report on the most recent updates on experimental drugs successfully employed in the treatment of the disease caused by SARS-CoV-2 coronavirus, also referred to as COVID-19 (COronaVIrus Disease-19). In particular, several cases of recovered patients have been reported after being treated with lopinavir/ritonavir [which is widely used to treat Human Immunodeficiency Virus (HIV) infection] in combination with the anti-flu drug oseltamivir. In addition, remdesivir, which has been previously administered to Ebola virus patients, has also proven effective in the U.S. against coronavirus, while antimalarial chloroquine and hydroxychloroquine, favipiravir and co-administered darunavir and umifenovir (in patient therapies) were also recently recorded as having anti-SARS-CoV-2 effects. Since the recoveries/deaths ratio in the last weeks significantly increased, especially in China, it is clear that the experimental antiviral therapy, together with the availability of intensive care unit beds in hospitals and rigorous government control measures, all play an important role in dealing with this virus. This also stresses the urgent need for the scientific community to devote its efforts to the development of other more specific antiviral strategies.

The novel coronavirus (COVID-19) is currently in epidemic stage. After large-scale interpersonal infection, asymptomatic patients appear. Whether asymptomatic patients are contagious or not and whether they need medication are the arguments among clinical experts.. This paper reports a special asymptomatic couple with COVID-19, of which the male patient is an intercity bus driver but has not induced confirmed infection of his 188 passengers. The patients were treated with four combinations of lopinavir/ritonavir tablets, arbidol tablets, Lianhuaqingwen granules, and recombinant human interferon-α2b (IFN-α2b) injection via aerosol. Their clinical characteristics and medication were summarized and analyzed.. The two asymptomatic patients far away from Wuhan did not seem to be highly contagious. They improved obviously, after treatment with the quadruple therapy, but the effective drug is still unknown. It should be noted that lopinavir/ritonavir tablets have many drug interactions and are the most likely drugs to cause hyperlipidemia and hyperglycemia in these two patients. IFN-α2b is more effective in the early stage of virus infection. Arbidol instruction dose may not be sufficient to inhibit the novel coronavirus

Since the outbreak of coronavirus disease (COVID-19) that was discovered in 2019 in Wuhan, China, no standard therapy guideline has been set despite the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its high infectivity. The globally pandemic outbreak suggests that COVID-19 is highly infectious and difficult to control. A dual-combination of ribavirin and interferon-α has been the widely used regimen for the treatment of this disease in China. However, due to the varying results of treatment with these drugs, a novel antiviral combination therapy is urgently needed. This case reports the usage of lopinavir/ritonavir-based combination antiviral regimen for a patient with SARS-CoV-2 infection.

Interferons (IFNs) are widely used in treating coronavirus disease 2019 (COVID-19) patients. However, a recent report of ACE2, the host factor mediating SARS-Cov-2 infection, identifying it as interferon-stimulated raised considerable safety concern. To examine the association between the use and timing of IFN-α2b and clinical outcomes, we analyzed in a retrospective multicenter cohort study of 446 COVID-19 patients in Hubei, China. Regression models estimated that early administration (≤5 days after admission) of IFN-α2b was associated with reduced in-hospital mortality in comparison with no admission of IFN-α2b, whereas late administration of IFN-α2b was associated with increased mortality. Among survivors, early IFN-α2b was not associated with hospital discharge or computed tomography (CT) scan improvement, whereas late IFN-α2b was associated with delayed recovery. Additionally, early IFN-α2b and umifenovir alone or together were associated with reduced mortality and accelerated recovery in comparison with treatment with lopinavir/ritonavir (LPV/r) alone. We concluded that administration of IFN-α2b during the early stage of COVID-19 could induce favorable clinical responses.

Presentation of a case illustrating the benefits of traditional Chinese medicine (TCM) for treatment of Coronavirus disease 2019 (COVID-19) in critically ill patients.. A 58-year-old woman presented with cough, fever, dizziness, chest tightness, polypnea and poor appetite. She was admitted to Guizhou Provincial People's hospital, and diagnosed with critically ill type of COVID-19 in February 2020. According to the patient's symptoms and signs, the TCM syndrome differentiation was qi deficiency, dampness-stasis and toxin accumulation. Then she received the combined therapy of a modified Chinese herbal formula and Western medicine. During a twelve-day period of treatment, her respiratory distress and appetite quickly improved. Abnormal laboratory indicators were resumed in time and lung lesions in CT scan largely absorbed. No side effects associated with this Chinese herbal formula were found. Before discharge, two consecutive nasopharyngeal swabs were shown to be negative for severe acute respiratory coronavirus 2 (SARS-CoV-2).. Our case report suggests that collaborative treatments with traditional Chinese medicine prove beneficial in the management of COVID-19 in critically ill patients. In order to give optimal care for this COVID-19 crisis for the whole world, Chinese medicine practitioners and Western medical doctors should work together in frontline.
