-- Veklury Is First and Only FDA-Approved Treatment for COVID-19 in the United States --

-- Veklury Shortened Time to Recovery By Five Days in Hospitalized COVID-19 Patients --

FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the U.S. Food and Drug Administration (FDA) has approved the antiviral drug Veklury® (remdesivir) for the treatment of patients with COVID-19 requiring hospitalization. As an antiviral drug, Veklury works to stop replication of SARS-CoV-2, the virus that causes COVID-19. Previously authorized by the FDA for emergency use to treat COVID-19, Veklury is now the first and only approved COVID-19 treatment in the United States. The drug is now widely available in hospitals across the country, following early investments to rapidly expand manufacturing capacity to increase supply.

In the United States, Veklury is indicated for adults and pediatric patients (12 years of age and older and weighing at least 40 kg) for the treatment of COVID-19 requiring hospitalization. Veklury should only be administered in a hospital or in a healthcare setting capable of providing acute care comparable to inpatient hospital care. Veklury is contraindicated in patients who are allergic to Veklury or any of its components; please see below for additional Important Safety Information for Veklury.

This approval is based on three randomized controlled trials including the recently published, final results of the National Institute of Allergy and Infectious Diseases’ (NIAID) double blind, placebo-controlled Phase 3 ACTT-1 trial, which showed that treatment with Veklury resulted in clinically meaningful improvements across multiple outcome assessments compared with placebo in hospitalized patients with COVID-19. Based on the strength of these data, Veklury has become a standard of care for the treatment of COVID-19 in hospitalized patients.

“The approval of Veklury marks an important milestone in efforts to help address the pandemic by offering an effective treatment that helps patients recover faster and, in turn, helps preserve scarce healthcare resources,” said Barry Zingman, MD, Professor of Medicine at the Albert Einstein College of Medicine and Montefiore Medical Center, New York. “The availability of a rigorously tested treatment that can significantly speed recovery and offers other benefits such as lower rates of progression to mechanical ventilation, provides hospitalized patients and their families important hope and offers healthcare providers a critical tool as they care for patients in need.”

“Since the beginning of the COVID-19 pandemic, Gilead has worked relentlessly to help find solutions to this global health crisis. It is incredible to be in the position today, less than one year since the earliest case reports of the disease now known as COVID-19, of having an FDA-approved treatment in the U.S. that is available for all appropriate patients in need,” said Daniel O’Day, Chairman and Chief Executive Officer, Gilead Sciences. “The speed and rigor with which Veklury has been developed and approved in the U.S. reflect the shared commitment of Gilead, government agencies and clinical trial investigators to advance well-tolerated, effective treatment options for the fight against COVID-19. We will continue to work at speed with the aim of enhancing patient outcomes with Veklury to ensure all patients with COVID-19 have the best chance at recovery.”

In the randomized, double-blind, placebo-controlled ACTT-1 trial, Veklury significantly improved time to recovery as compared to placebo – by five days in the overall study population (10 vs. 15 days; rate ratio, 1.29; 95% CI, 1.12 to 1.49; p94% and radiological evidence of pneumonia. The primary endpoint was clinical status on Day 11 assessed on a 7-point ordinal scale.

About Veklury

Veklury (remdesivir) is a nucleotide analog invented by Gilead, building on more than a decade of the company’s antiviral research. Veklury has broad-spectrum antiviral activity both in vitro and in vivo in animal models against multiple emerging viral pathogens, including Ebola, SARS, Marburg, MERS and SARS-CoV-2, the virus that causes COVID-19.

Veklury has been approved or authorized for temporary use as a COVID-19 treatment in approximately 50 countries worldwide. In our continuing commitment to develop effective treatments for COVID-19, multiple ongoing international Phase 3 clinical trials are evaluating the safety and efficacy of Veklury for the treatment of COVID-19, in different patient populations, formulations, and in combination with other therapies.

As announced on October 1, 2020, Gilead is now meeting real-time demand for Veklury in the United States and anticipates meeting global demand for Veklury in October, even in the event of potential future surges of COVID-19.

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. Monitor patients under close medical supervision for hypersensitivity reactions during and following administration of VEKLURY. Symptoms may include hypotension, hypertension, tachycardia, bradycardia, hypoxia, fever, dyspnea, wheezing, angioedema, rash, nausea, diaphoresis, and shivering. Slower infusion rates (maximum infusion time ≤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 due to antagonism observed in cell culture, 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 ≥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 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
