What is Coronavirus disease (COVID-19)?

From the Guidelines

COVID-19 patients should be managed based on the severity of their symptoms, with a focus on supportive care, antiviral medications for high-risk individuals, and prevention through vaccination. The management of COVID-19 involves understanding the disease's biphasic nature, with an initial stage of infection followed by a potential second phase characterized by a dysfunctional host inflammatory response 1. Symptoms of COVID-19 can range from mild to severe and include fever, cough, fatigue, shortness of breath, and loss of taste or smell.

Key Considerations

• The disease's severity and risk of hospitalization and mortality are influenced by factors such as age, sex, number of comorbidities, and specific clinical markers like respiratory rate, oxygen saturations, and C-reactive protein 1.
• Antiviral, immunosuppressive, and immunomodulatory treatments have been explored, with randomized clinical trials providing evidence for specific interventions 1.
• Prevention through vaccination is crucial, as it significantly reduces the risk of severe illness, hospitalization, and death.

Management Approach

• For mild cases, symptom management with rest, hydration, and over-the-counter medications like acetaminophen for fever and pain is recommended.
• High-risk individuals may benefit from antiviral medications, such as those prescribed within 5 days of symptom onset.
• Prevention measures, including vaccination, wearing masks in crowded indoor settings, maintaining good hand hygiene, and improving ventilation, are essential to reduce transmission.

Ongoing Considerations

• The ongoing circulation of COVID-19 necessitates continued vigilance and adherence to preventive measures and management strategies.
• Immunity from vaccination and prior infection has contributed to a reduction in the disease's impact, alongside improved treatments and management strategies 1.

From the FDA Drug Label

VEKLURY is a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleotide analog RNA polymerase inhibitor indicated for the treatment of coronavirus disease 2019 (COVID-19) in adults and pediatric patients (birth to less than 18 years of age weighing at least 1.5 kg) who are: Hospitalized, or Not hospitalized and have mild-to-moderate COVID-19, and are at high risk for progression to severe COVID-19, including hospitalization or death. The answer to the question about Covid is that remdesivir (IV) is indicated for the treatment of COVID-19 in certain patients, including those who are:

• Hospitalized
• Not hospitalized with mild-to-moderate COVID-19 and at high risk for progression to severe COVID-19 2

From the Research

Covid-19 Treatment Options

• The use of remdesivir and corticosteroids has been studied as a potential treatment for Covid-19, with varying results 3, 4, 5, 6, 7.
• A Bayesian re-analysis of clinical trial data found that remdesivir had a low probability of achieving a clinically meaningful reduction in mortality, except for patients needing supplemental oxygen without mechanical ventilation 3.
• Another study found that remdesivir was associated with a lower mortality rate and higher rates of extubation and hospital discharge in patients requiring mechanical ventilation 4.

Remdesivir and Corticosteroid Combination Therapy

• A study comparing the outcomes of combined corticosteroid and remdesivir therapy with corticosteroid monotherapy in ventilated Covid-19 patients found that the combination therapy was non-inferior to corticosteroid monotherapy in reducing 28-day all-cause in-hospital mortality 5.
• Another study found that early combination treatment with remdesivir and high-dose corticosteroid pulse therapy reduced in-hospital mortality and the need for admission to the ICU in patients with severe Covid-19 pneumonia 6.

Remdesivir Treatment Outcomes

• A retrospective study of patients with Covid-19 pneumonia requiring high oxygen support found that remdesivir treatment was associated with high recovery rates and low all-cause mortality 7.
• The study also found that the majority of patients who received remdesivir therapy achieved clinical improvement within 28 days, with a significant proportion of patients being discharged from the hospital 7.

Adverse Events

• The most frequent adverse events associated with remdesivir treatment were sinus bradycardia and alanine transaminase increase, with almost all adverse events being classified as Grades 1-3 7.
