Abstract Background Remdesivir is FDA approved for the treatment of hospitalized patients with COVID-19 and has been shown to shorten time to recovery and improve clinical outcomes in randomized trials. Methods This was the final day 28 comparative analysis of data from a phase 3, randomized, open-label study comparing 2 remdesivir regimens (5 vs 10 days, combined for this analysis [remdesivir cohort]) and a real-world retrospective longitudinal cohort study of patients receiving standard-of-care treatment (non-remdesivir cohort). Eligible patients, aged ≥18 years, had confirmed SARSCoV-2, oxygen saturation ≤94% on room air or required supplemental oxygen, with pulmonary infiltrates. Propensity score matching (up to 1:10 ratio) was used to ensure comparable populations. We assessed day 14 clinical recovery (determined using a 7-point ordinal scale) and day 28 all-cause mortality (coprimary endpoints). Results Altogether, 368 (remdesivir) and 1399 (non-remdesivir) patients were included in the matched analysis. The day 14 clinical recovery rate was significantly higher among the remdesivir versus the non-remdesivir cohort (65.2% vs 57.1%; OR 1.49, 95% CI 1.16–1.90; P = .002). The day 28 mortality rate was significantly lower in the remdesivir cohort versus the non-remdesivir cohort (12.0% vs 16.2%; OR 0.67, 95% CI 0.47–0.95; P = .03). Conclusions Remdesivir was associated with significantly higher rates of day 14 clinical recovery, and lower day 28 mortality, compared with standard-of-care treatment in hospitalized patients with COVID-19. Collectively, these data support the use of remdesivir to improve clinical recovery and decrease mortality from SARS-CoV-2 infection.

Abstract Background We compared the efficacy of the antiviral agent, remdesivir, versus standard-of-care treatment in adults with severe coronavirus disease 2019 (COVID-19) using data from a phase 3 remdesivir trial and a retrospective cohort of patients with severe COVID-19 treated with standard of care. Methods GS-US-540–5773 is an ongoing phase 3, randomized, open-label trial comparing two courses of remdesivir (remdesivir-cohort). GS-US-540–5807 is an ongoing real-world, retrospective cohort study of clinical outcomes in patients receiving standard-of-care treatment (non-remdesivir-cohort). Inclusion criteria were similar between studies: patients had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, were hospitalized, had oxygen saturation ≤94% on room air or required supplemental oxygen, and had pulmonary infiltrates. Stabilized inverse probability of treatment weighted multivariable logistic regression was used to estimate the treatment effect of remdesivir versus standard of care. The primary endpoint was the proportion of patients with recovery on day 14, dichotomized from a 7-point clinical status ordinal scale. A key secondary endpoint was mortality. Results After the inverse probability of treatment weighting procedure, 312 and 818 patients were counted in the remdesivir- and non-remdesivir-cohorts, respectively. At day 14, 74.4% of patients in the remdesivir-cohort had recovered versus 59.0% in the non-remdesivir-cohort (adjusted odds ratio [aOR] 2.03: 95% confidence interval [CI]: 1.34–3.08, P < .001). At day 14, 7.6% of patients in the remdesivir-cohort had died versus 12.5% in the non-remdesivir-cohort (aOR 0.38, 95% CI: .22–.68, P = .001). Conclusions In this comparative analysis, by day 14, remdesivir was associated with significantly greater recovery and 62% reduced odds of death versus standard-of-care treatment in patients with severe COVID-19. Clinical Trials Registration NCT04292899 and EUPAS34303.

Abstract Background: The COVID-19 pandemic, caused by the human coronavirus SARS CoV-2, has led to millions of deaths across the globe. Not only is the SARS CoV-2 virus highly infectious, it also mutates very easily. This creates additional challenges for development of robust therapeutic solutions. Along with modern system of healthcare, there is a definite need for exploring natural plant based antiviral compounds directed against the SARS CoV-2 virus. Objective: The present observational study investigates the efficacy of an Ayurvedic polyherbal formulation of 19 ingredients, NOQ19, in the management of COVID-19. Methodology: A single arm, single centric, open label study design was adopted for this feasibility study. 161 RT-PCR positive COVID-19 patients were enrolled. The enrolled participants were provided the Ayurvedic intervention, 2 tablets of NOQ19, thrice daily along with the standard of care treatment. Follow up COVID-19 RT- PCR tests were conducted on Day 5, Day 10 and Day 14, or until the patient turned negative. The time required for testing negative on the RT-PCR test or becoming asymptomatic was noted. Results: A subjective analysis demonstrated that 74% of patients turned RT-PCR negative within 5 days of taking NOQ19. Additionally, 98% of the subjects turned RT-PCR Negative on Day 10 after taking NOQ19 in addition to the standard of care treatment of Vitamin C , Zinc and antipyretic (as necessary). None of the participants reported any adverse or side effects to the medication.Conclusion: NOQ19 Ayurvedic polyherbal formulation can be an effective and safe option for the symptomatic management of COVID-19.

Background: Globally there is a scarcity of effective treatments for SARS-CoV-2 infections (causing COVID 19). Repurposing existing medications may offer the best hope for treating COVID 19 patients to curb the pandemic. IMU-838 is a dihydroorotate dehydrogenase (DHODH) inhibitor, which is an effective mechanism for antiviral effects against respiratory viruses. When used synergistically with Oseltamivir, therapeutic effects have been observed against influenza and SARS-CoV-2 in rodents.(13) The IONIC trial is a randomized control trial that will investigate whether time to clinical improvement in COVID 19 patients is improved following a 14 day course of IMU-838 + Oseltamivir versus Oseltamivir alone. Methods: IONIC trial is an open label study in which participants will be randomised 1:1 in two parallel arms; the intervention arm (IMU-838 + Oseltamivir) and control arm (Oseltamivir only). The primary outcome is time-to-clinical improvement; defined as the time from randomisation to: a 2-point improvement on WHO ordinal scale; discharge from hospital, or death (whichever occurs first). The study is sponsored by UHCW NHS Trust and funded by LifeArc. Discussion: The IONIC Protocol describes an overarching trial design to provide reliable evidence on the efficacy of IMU-838 (vidofludimus calcium) when delivered in combination with an antiviral therapy (Oseltamivir) [IONIC Intervention] for confirmed or suspected COVID-19 infection in adult patients receiving usual standard of care. Trial Registration: The trial was registered with EudraCT (2020-001805-21) on 09.04.2020 and ISRCTN on 23.09.2020 (ISRCTN53038326) and Clinicaltrials.gov on 17.08.2020 (NCT04516915) Strengths and Limitations: This study is the first to recruit participants in the trial exploring the effectiveness of IMU-838 in COVID-19. In addition, we believe it is the only trial exploring the effectiveness of IMU-838 in combination with Oseltamivir (Tamiflu) in patients with moderate to severe COVID-19. However, to make the trial design flexible due to the on-going pandemic the trial is un-blinded.

Abstract BACKGROUND: Calcium release-activated calcium (CRAC) channel inhibitors stabilize the pulmonary endothelium and block proinflammatory cytokine release, potentially mitigating respiratory complications observed in patients with COVID-19. This study aimed to investigate the safety and efficacy of Auxora, a novel, intravenously administered CRAC channel inhibitor, in adults with severe or critical COVID-19 pneumonia METHODS: A randomized, controlled, open-label study of Auxora was conducted in adults with severe or critical COVID-19 pneumonia. Patients were randomized 2:1 to receive three doses of once-daily Auxora versus standard of care (SOC) alone. The primary objective was to assess safety and tolerability of Auxora. Following FDA guidance, study enrollment was halted early to allow for transition to a randomized, blinded, placebo-controlled study. RESULTS: In total, 17 patients with severe and three with critical COVID-19 pneumonia were randomized to Auxora and nine with severe and one with critical COVID-19 pneumonia to SOC. Similar proportions of patients receiving Auxora and SOC experienced ≥1 adverse event (75% versus 80%, respectively). Fewer patients receiving Auxora experienced serious adverse events versus SOC (30% versus 50%, respectively). Two patients (10%) receiving Auxora and two (20%) receiving SOC died in the 30 days after randomization. Among patients with severe COVID-19 pneumonia, median time to recovery with Auxora was five days versus 12 days with SOC; recovery rate ratio was 1.87 (95%CI, 0.72, 4.89). Invasive mechanical ventilation was needed in 18% of patients with severe COVID-19 pneumonia receiving Auxora versus 50% receiving SOC (absolute risk reduction=32%; 95%CI, -0.07, 0.71). Outcomes measured by an 8-point ordinal scale were significantly improved for patients receiving Auxora, especially for patients with a baseline PaO2/FiO2=101-200. CONCLUSIONS: Auxora demonstrated a favorable safety profile in patients with severe or critical COVID-19 pneumonia and improved outcomes in patients with severe COVID-19 pneumonia. These results, however, are limited by the open-label study design and small patient population resulting from early cessation of enrollment in response to regulatory guidance. The impact of Auxora on respiratory complications in patients with severe COVID-19 pneumonia will be further assessed in a planned randomized, blinded, placebo-controlled study.
