Baricitinib for COVID-19

November 19, 2020

Baricitinib is authorized for use under an Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA), in combination with remdesivir, for treatment of suspected or laboratory confirmed coronavirus disease 2019 (COVID-19) in hospitalized adults and pediatric patients 2 years of age or older requiring supplemental oxygen, invasive mechanical ventilation, or extracorporeal membrane oxygenation (ECMO). For information on the authorized use of baricitinib and mandatory requirements under the EUA, please visit

The authorization is based on data from the Adaptive COVID-19 Treatment Trial (ACTT-2), a study investigating baricitinib conducted by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). This randomized, double-blind, placebo-controlled clinical trial began in May 2020 to evaluate a treatment regimen of baricitinib in combination with remdesivir in hospitalized adult patients with moderate to severe disease.

Baricitinib has not been approved by the FDA for the treatment of COVID-19. Baricitinib is authorized under an EUA only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of baricitinib under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. Under the EUA, baricitinib is available as 1-mg and 2-mg tablets.

Important Safety Information

The following provides essential safety information on the unapproved use of baricitinib under the Emergency Use Authorization.


  • Serious Infections: Serious infections have occurred in patients receiving baricitinib. Avoid the use of baricitinib with known active tuberculosis. Consider if the potential benefits outweigh the potential risks of baricitinib treatment in patients with active serious infections other than COVID-19 or chronic/recurrent infections.

  • Thrombosis: In hospitalized patients with COVID-19, prophylaxis for venous thromboembolism is recommended unless contraindicated. If clinical features of deep vein thrombosis or pulmonary embolism occur, patients should be evaluated promptly and treated appropriately.

  • Abnormal Laboratory Values: Evaluate at baseline and thereafter according to local patient management practice. Monitor closely when treating patients with abnormal baseline and post-baseline laboratory values. Follow dose adjustments as recommended in the Fact Sheet for Healthcare Providers for patients with abnormal renal, hematological and hepatic laboratory values. Manage patients according to routine clinical guidelines.

  • Hypersensitivity: If a serious hypersensitivity occurs, discontinue baricitinib while evaluating the potential causes of the reaction.

  • See Warnings and Precautions in the FDA-approved full Prescribing Information for additional information on risks associated with longer-term treatment with baricitinib.

  • Serious Side Effects: Serious venous thrombosis, including pulmonary embolism, and serious infections have been observed in COVID-19 patients treated with baricitinib and are known adverse drug reactions of baricitinib.

  • There are limited clinical data available for baricitinib use in coronavirus 2019 (COVID-19). Additional information regarding baricitinib for its FDA-approved indication, including safety information, may be found in the full Prescribing Information, including Boxed Warning about Serious Infections, Malignancies, and Thrombosis, and Medication Guide.

Use in Specific Populations

  • Pregnancy: Baricitinib should be used during pregnancy only if the potential benefit justifies the potential risk for the mother and the fetus.

  • Renal Impairment: There are limited data for baricitinib in patients with severe renal impairment. Baricitinib is not recommended for patients who are on dialysis, have end-stage renal disease, or have acute kidney injury.

  • Hepatic Impairment: Baricitinib has not been studied in patients with severe hepatic impairment. Baricitinib should only be used in patients with severe hepatic impairment if the potential benefit outweighs the potential risk.
