-- If Granted by the European Commission, Veklury will Become the Only Direct-Acting Antiviral with Full Marketing Authorization in the EU --

FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Commission (EC) adopted a positive opinion on the fulfillment of the last specific obligation and recommended the granting of Marketing Authorization (MA) for Veklury® (remdesivir) that is no longer subject to specific obligations. Veklury was initially granted a conditional marketing authorization in July 2020 for the treatment of COVID-19 in adults and adolescents (from 12 years of age and weighing at least 40 kilograms) with pneumonia requiring supplemental oxygen (low- or high-flow oxygen or other non-invasive ventilation at the start of treatment). In December of 2021, the conditional authorization was expanded to include adults who do not require supplemental oxygen and are at increased risk of developing severe COVID-19. The EC will review the CHMP recommendation and, pending adoption, Veklury will be fully authorized for these patients with COVID-19.

“We welcome the Committee’s positive opinion recommending a full marketing authorization for Veklury. Veklury continues to demonstrate durable activity against SARS-CoV-2 as it evolves, and it is the most used antiviral in hospitalized patients,” said Merdad Parsey, MD, PhD, Chief Medical Officer of Gilead. “More than two years into this pandemic, it’s critical to continue to secure access to effective treatments. We are proud of the role Veklury plays as the COVID-19 antiviral standard of care for hospitalized patients, and we remain committed to make it available to all patients that can benefit from it. We look forward to the EC’s decision.”

This positive opinion is based upon the fulfilment of the last specific obligation for Veklury, which included the review of virology data inclusive of in vitro data showing Veklury retains activity against variants of concern, including Alpha, Beta, Gamma, Delta and Omicron (BA.1 and BA.2). In addition, an assessment of the current risk-benefit of Veklury, which considered the efficacy and safety data accumulated since the initial granting of the conditional marketing authorization, was reviewed by the CHMP to support the change to a full marketing authorization.

In the European Economic Area (EEA), Veklury is the only antiviral indicated for both the treatment of COVID-19 in adult and adolescent patients with pneumonia requiring supplemental oxygen (low- or high-flow oxygen or other non-invasive ventilation) and adults who do not require supplemental oxygen and are at increased risk of developing severe COVID-19.

About Veklury

Veklury (remdesivir) is a nucleotide analog invented by Gilead, building on more than a decade of the company’s antiviral research. Veklury is a foundation for the treatment of hospitalized patients with COVID-19 and is a recommended treatment for reducing disease progression in non-hospitalized patients at high risk of disease progression. Veklury has an established safety profile and minimal drug interactions in diverse populations. It can help reduce disease progression across a spectrum of disease severity and enable patients to recover faster, freeing up limited hospital resources and saving healthcare systems money.

Veklury directly inhibits viral replication inside of the cell by targeting the SARS-CoV-2 viral RNA polymerase. Based on sequence analyses, Veklury should remain active against Omicron BA.4 and BA.5, as there are no new substitutions in the polymerase of BA.4 and BA.5. This suggests that Veklury will continue to be active against known Omicron variants. Gilead continuously evaluates the activity of Veklury against new SARS-CoV-2 variants of concern as they emerge around the world.

Veklury is approved in 50 countries worldwide. To date, Veklury and generic remdesivir have been made available to more than 11 million patients around the world, including more than 7 million people in 127 middle- and low-income countries through Gilead’s voluntary licensing program. These licenses currently remain royalty-free, reflecting Gilead’s existing commitment to enabling broad patient access to remdesivir.

U.S. Indication for Veklury

Veklury® (remdesivir 100 mg for injection) is indicated for the treatment of COVID-19 in adults and pediatric patients (≥28 days old and weighing ≥3 kg) with positive results of SARS-CoV-2 viral testing, 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.

U.S. Important Safety Information for Veklury

Contraindication

Veklury is contraindicated in patients with a history of clinically significant hypersensitivity reactions to Veklury or any of its components.

Warnings and precautions

• Hypersensitivity, including infusion-related and anaphylactic reactions: Hypersensitivity, including infusion-related and anaphylactic reactions, has been observed during and following administration of Veklury; most occurred within one hour. Monitor patients during infusion and observe for at least one hour after infusion is complete for signs and symptoms of hypersensitivity as clinically appropriate. Symptoms may include hypotension, hypertension, tachycardia, bradycardia, hypoxia, fever, dyspnea, wheezing, angioedema, rash, nausea, diaphoresis, and shivering. Slower infusion rates (maximum infusion time up to 120 minutes) can potentially prevent these reactions. If a severe infusion-related hypersensitivity reaction occurs, immediately discontinue Veklury and initiate appropriate treatment (see Contraindications).
• Increased risk of transaminase elevations: Transaminase elevations have been observed in healthy volunteers and in patients with COVID-19 who received Veklury; these elevations have also been reported as a clinical feature of COVID-19. Perform hepatic laboratory testing in all patients (see Dosage and administration). Consider discontinuing Veklury if ALT levels increase to >10x ULN. Discontinue Veklury if ALT elevation is accompanied by signs or symptoms of liver inflammation.
• Risk of reduced antiviral activity when coadministered with chloroquine or hydroxychloroquine: Coadministration of Veklury with chloroquine phosphate or hydroxychloroquine sulfate is not recommended based on data from cell culture experiments, demonstrating potential antagonism, which may lead to a decrease in antiviral activity of Veklury.

Adverse reactions

• The most common adverse reaction (≥5% all grades) was nausea.
• The most common lab abnormalities (≥5% all grades) were increases in ALT and AST.

Drug interactions

• Drug interaction trials of Veklury and other concomitant medications have not been conducted in humans.

Dosage and administration

• Dosage: For adults and pediatric patients 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. For pediatric patients ≥28 days and weighing ≥3 kg: 5 mg/kg on Day 1, followed by once-daily maintenance doses of 2.5 mg/kg from Day 2, administered only via intravenous infusion.
• Treatment duration:
  • For hospitalized patients requiring invasive mechanical ventilation and/or ECMO, the recommended total treatment duration is 10 days. Veklury should be initiated as soon as possible after diagnosis of symptomatic COVID-19.
  • For hospitalized patients not requiring invasive mechanical ventilation and/or ECMO, the recommended treatment duration is 5 days. If a patient does not demonstrate clinical improvement, treatment may be extended for up to 5 additional days for a total treatment duration of up to 10 days.
  • For non-hospitalized patients diagnosed with mild-to-moderate COVID-19 who are at high risk for progression to severe COVID-19, including hospitalization or death, the recommended total treatment duration is 3 days. Veklury should be initiated as soon as possible after diagnosis of symptomatic COVID-19 and within 7 days of symptom onset.
• Testing prior to and during treatment: Perform eGFR, hepatic laboratory and prothrombin time testing prior to initiating Veklury and during use as clinically appropriate.
• Renal impairment: Veklury is not recommended in individuals with eGFR
