Veklury (Remdesivir) Antiviral Treatment Description
Veklury (remdesivir; GS-5734) is a nucleotide analog with broad-spectrum antiviral activity. Gilead's Veklury demonstrated in vitro and in vivo activity in animal models against the viral pathogens MERS and SARS, coronaviruses, and are structurally similar to SARS-CoV-2 causes COVID-19.
Gilead Sciences' Veklury (remdesivir) acts to inhibit the SARS-CoV-2 RNA-dependent RNA polymerase, which is essential for viral replication, says the company. Veklury (remdesivir) is administered through a vein by intravenous infusion, one time each day for up to 10 days, as determined by your healthcare provider, says Gilead Sciences.
Veklury is a prodrug that distributes into cells where it is metabolized into the pharmacologically active remdesivir triphosphate (RDV-TP). RDV-TP acts as an analog of ATP and competes with it for incorporation into nascent viral RNA. Incorporating RDV-TP into nascent viral RNA results in delayed chain termination (position i+3), disrupting SARS-CoV-2 viral RNA replication.
Gilead Sciences, Inc. announced on October 22, 2020, that the U.S. Food and Drug Administration (FDA) has approved the antiviral drug Veklury® (remdesivir) for use in adult and pediatric patients 12 years of age and older and weighing at least 40 kilograms (about 88 pounds) for the treatment of COVID-19 requiring hospitalization. In addition, on March 7, 2021, the European Medicines Agency issued marketing approval in the EU.

Veklury (Remdesivir) Antiviral History
As of May 1, 2020, Veklury (remdesivir) was issued an Emergency Use Authorization in the USA for hospitalized with severe disease. The FDA authorized the use of Veklury (remdesivir) to treat hospitalized adult and pediatric patients with suspected or laboratory-confirmed SARS-CoV-2 infection and severe COVID-19 disease.
On May 12, 2020, Mylan N.V. announced a license agreement signed with Gilead to manufacture and distribute Veklury (remdesivir) in 127 low- and middle-income countries, including India. In India, Mylan will launch the drug under the brand name DESREM.
And on May 26, 2020, the UK Department of Health announced that adults and teenagers with severe COVID-19 would be treated with Veklury (remdesivir) if they fit specific criteria.
On June 15, 2020, the FDA issued a drug interaction alert regarding the co-administration of Veklury (remdesivir) and chloroquine phosphate, or hydroxychloroquine sulfate may result in reduced antiviral activity. The U.S. FDA announced on August 28, 2020, broadened the scope of the existing EUA for Veklury to include treatment of all hospitalized adult and pediatric patients with suspected or laboratory-confirmed COVID-19, irrespective of their severity of the disease.
On October 1, 2020, the U.S. HHS announced the Office of the Assistant Secretary for Preparedness and Response records indicate that of the 500,000 treatment courses of Veklury made available in the USA between July and September 2020, state and territorial health departments accepted 84% of their allocations (423,765 treatment courses); however, only 32% (160,981 treatment courses) of the total allocation was actually purchased by hospitals in their jurisdictions.
The U.S. FDA approved the antiviral drug Veklury (remdesivir) on October 22, 2020, for use in adult and pediatric patients 12 years of age and older and weighing at least 40 kilograms for the treatment of COVID-19 requiring hospitalization. Thus, Veklury is the first treatment for COVID-19 to receive FDA approval. Furthermore, on December 3, 2020, the U.S. NIH stated: 'Remdesivir, an antiviral agent, is recommended for use in hospitalized patients who require supplemental oxygen. However, it is not routinely recommended for patients who require mechanical ventilation due to the lack of data showing benefit at this advanced stage of the disease.'
A study published by the NEJM on December 11, 2020, found 'The results of this randomized, double-blind, placebo-controlled trial show that combination treatment with the anti-inflammatory drug baricitinib and the antiviral drug remdesivir was safe and superior to remdesivir alone for the treatment of hospitalized patients with Covid-19 pneumonia.'
On February 12, 2021, the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency concluded its review of a safety signal to assess acute kidney injury reports in patients with COVID-19 treated Veklury (remdesivir). The PRAC assessed all available information, including data provided by the marketing authorization holder, analysis of reported adverse reactions, data from clinical trials, and published scientific literature. After considering all the data, the PRAC concluded that there is no evidence indicating that the reported kidney problems are associated with Veklury.
Gilead Science first received a patent (US9724360B2) for the drug (remdesivir) to treat Ebola in 2017. In fall 2015, Gilead applied for two patents for remdesivir, one for combating coronaviruses and another for filoviruses, the family of pathogens that includes Ebola. Both were approved in spring 2019.
Gilead Science, Inc. is located in Foster City, CA 94404.
Veklury (Remdesivir) Antiviral Use in Pregnant and Lactating Women
Pregnancy: There is insufficient human data on the use of Veklury during pregnancy. Pregnant women hospitalized with COVID-19 are at risk for serious morbidity and mortality. Veklury should be used during pregnancy only if the potential benefit justifies the potential risk for the mother and the fetus. Lactation: It is not known whether Veklury can pass into breast milk. Breastfeeding individuals with COVID-19 should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19.
Veklury (Remdesivir) Antiviral Warnings and Precautions
Veklury is contraindicated in patients with a history of clinically significant hypersensitivity reactions to Veklury or any of its components. Hypersensitivity, including infusion-related and anaphylactic reactions, has been observed during and following the administration of Veklury. Drug interaction trials of Veklury and other concomitant medications have not been conducted in humans.
Veklury (Remdesivir) Antiviral Dosage and Administration
Dosage: For adults and pediatric patients ≥12 years old and weighing ≥40 kg: 200 mg on Day 1, followed by once-daily maintenance doses of 100 mg from Day 2 administered only via intravenous infusion over 30 to 120 minutes. Treatment duration: For patients not requiring invasive mechanical ventilation and/or extracorporeal membrane oxygenation (ECMO): 5 days; may be extended up to 5 additional days (10 days total) if clinical improvement is not observed. For patients requiring invasive mechanical ventilation and/or ECMO: 10 days. Testing before and during treatment: Perform eGFR, hepatic laboratory, and prothrombin time testing before initiating Veklury and during use as clinically appropriate. Renal impairment: Veklury is not recommended in individuals with eGFR <30 mL/min.
Voluntary Licensing Agreements for Veklury (Remdesivir)
In May 2020, Gilead announced non-exclusive voluntary licensing agreements with generic pharmaceutical manufacturers based in Egypt, India, and Pakistan to expand the supply of remdesivir further. The agreements allow the companies – Cipla Ltd.; Dr. Reddy's Laboratories Ltd.; Eva Pharma; Ferozsons Laboratories; Hetero Labs Ltd.; Jubilant Lifesciences; Mylan; Syngene, a Biocon company; and Zydus Cadila Healthcare Ltd. – to manufacture remdesivir for distribution in 127 countries. The countries consist of nearly all low-income and lower-middle-income countries and several upper-middle- and high-income countries that face significant obstacles to healthcare access.
Veklury (Remdesivir) Antiviral Delivery
The Veklury (remdesivir) FDA approval includes two presentations: remdesivir for injection, 100 milligrams (mg), a sterile, preservative-free lyophilized powder, and remdesivir injection, 100 mg/20 milliliters (mL) (5 mg/mL), a sterile, preservative-free solution. Veklury is an injectable drug and should only be administered in a hospital or in a health care setting capable of providing acute care comparable to inpatient hospital care.
The U.S. FDA issued a caution on February 4, 2021, against compounding remdesivir drug products under section 503A of the Federal Food, Drug, and Cosmetic Act (FD&C Act). Drug products compounded by outsourcing facilities from bulk remdesivir do not qualify for the exemptions under section 503B of the FD&C Act unless remdesivir is added to the 503B bulks list or the approved remdesivir product appears on FDA’s drug shortage list.
India-based Zydus announced on March 24, 2021, its version of Remdesivir, Remdac, is more affordable at Rs. 899 for a 100 mg lyophilized injection. Remdac was launched in August 2020 at Rs. 2800.
