Bamlanivimab and Etesevimab COVID-19 Antibody Treatment Description

Eli Lilly's Bamlanivimab (LY-CoV555) neutralizing IgG1 monoclonal antibody (mAb) is directed against the spike protein of the SARS-CoV-2 coronavirus. Bamlanivimab was designed to block viral attachment and entry into human cells, thus neutralizing the virus, potentially preventing and treating COVID-19 patients. Bamlanivimab emerged from the collaboration between Lilly and AbCellera

Lilly scientists developed the mAb in less than three months and tested them at the NIAID Vaccine Research Center. Bamlanivimab and etesevimab are artificial neutralizing antibody drugs. When there's a virus in your body, like COVID-19, your immune system makes antibodies to fight it off. But it takes time for your body to produce antibodies for a new virus — and in the meantime, you could get very sick. Bamlanivimab and etesevimab do not have any COVID-19 virus in them.

Etesevimab (LY-CoV016, JS016) is a recombinant fully human monoclonal neutralizing antibody. Eli Lilly licensed etesevimab from Junshi Biosciences after jointly developed by Junshi and the Institute of Microbiology, Chinese Academy of Science.

On February 9, 2021, the U.S. FDA authorized bamlanivimab and etesevimab administered together to treat mild-to-moderate COVID-19 in adults and certain pediatric patients.

On December 3, 2021, the FDA issued a revised EUA for bamlanivimab and etesevimab (previously authorized for pediatric patients 12 years of age and older weighing at least 40 kilograms, or about 88 pounds), to additionally authorize bamlanivimab and etesivimab administered together for the treatment of mild to moderate COVID-19 in all younger pediatric patients, including newborns, who have a positive COVID-19 test and are at high risk for progression to severe COVID-19, including hospitalization or death. In addition, this revision also authorizes bamlanivimab and etesevimab to be administered together for post-exposure prophylaxis to prevent COVID-19 in all pediatric patients, including newborns, at high risk of progression severe COVID-19, including hospitalization or death. 

As of December 2021, please see the FDA Letter of Authorization and Fact Sheet for Parents-Caregivers, and FAQs on the Emergency Use Authorization for Bamlanivimab and Etesevimab.

Etesevimab Monoclonal Neutralizing Antibody

Etesevimab binds explicitly to the SARS-CoV-2 surface spike protein receptor-binding domain high affinity and can block the binding of the virus to the ACE2 host cell surface receptor. In addition, point mutations were introduced into the native human IgG1 antibody to mitigate effector function. As a result, the U.S. FDA published a revised Fact Sheet on March 20, 2021.

Junshi Biosciences has completed a similar Phase 1 study in healthy volunteers in China and globally as initiated Phase 1b/2 trials in COVID-19 patients. Junshi Biosciences (HKEX: 1877; SSE: 688180) leads development in Greater China, while Lilly leads growth in the rest of the world. In addition, a Phase 2 study assessing the efficacy and safety of bamlanivimab alone and bamlanivimab with other neutralizing antibodies versus placebo to treat symptomatic low-risk COVID-19 in the outpatient setting (BLAZE-4. NCT04634409) has completed enrollment.

Bamlanivimab and Etesevimab COVID-19 Antibody Effectiveness Against Omicron Variant

On December 23, 2021, the U.S. FDA issued an updated Provider Fact Sheet with specific information regarding expected activity against the Omicron variant (B.1.1.529/BA.1). These data show that it is unlikely that bamlanivimab and etesevimab administered together will retain activity against the Omicron variant.

As of January 17, 2022, the U.S. NIH's OpenData Portal reported in vitro Therapeutic Activity against the Omicron variant. Anti-SARS-CoV-2 mAbs that target the spike protein has been shown to have a clinical benefit in treating SARS-CoV-2 infection. But, given the breaking nature of these releases, Omicron data should be interpreted with caution.

Bamlanivimab and Etesevimab COVID-19 Antibody Availability

On January 17, 2022, the U.S. HHS Assistant Secretary for Preparedness and Response confirmed 44,550​​ doses of Bamlanivimab and Etesevimab were recently distributed in the U.S. Since September 13, 2021, about 850,000 treatments were shipped in the U.S. 

Patients and physicians can visit the NICA Infusion Center Locator or the HHS Therapeutics Distribution locator to find a potential therapy location. Please refer to the FDA webpage Bamlanivimab / Etesevimab Authorized States, Territories, and U.S. Jurisdictions for the latest information on bamlanivimab plus etesevimab distribution.

A current list of countries with a purchase agreement and regulatory authorization is found on this Eli Lilly webpage.

Bamlanivimab and Etesevimab COVID-19 Antibody Treatment History 

On November 9, 2020, the U.S. FDA issued a EUA for a single infusion of 700 mg bamlanivimab to treat mild-to-moderate COVID-19 in adult and certain pediatric patients. This EUA was revoked on March 2, 2021. On January 26, 2021, Lilly announced new data showing treatment with the neutralizing antibodies bamlanivimab and etesevimab reduces the risk of COVID-19 hospitalizations and death by 70%. On May 11, 2021, the US Centers for Medicare & Medicaid Service (CMS) confirmed the investigational monoclonal antibody therapies are available under FDA EUA.

In addition, the U.S. NIH information from the Panel's Statement on Bamlanivimab Plus Etesevimab is updated at Please see The Panel's Updated Statement on the Prioritization of Anti-SARS-CoV-2 Monoclonal Antibodies.

Bamlanivimab and Etesevimab COVID-19 Antibody Treatment Indication for Children

Bamlanivimab and Etesevimab treatment is indicated to prevent or mitigate the progression of COVID-19 infection caused by the SARS-CoV-2 coronavirus. Bamlanivimab and etesevimab were authorized on December 3, 2021, as the first and only neutralizing antibody therapy for emergency use in COVID-19 patients under the age of 12; the EUA was extended for the pediatric and infant population.

Bamlanivimab and Etesevimab COVID-19 Antibody Dosage

The authorized dosage for adults and certain pediatric patients (weighing at least 40 kg) is 700 mg bamlanivimab and 1,400 mg of etesevimab administered together as a single intravenous infusion.

Patients weighing less than 40 kg (88 pounds) received doses of bamlanivimab and etesevimab adjusted for their body weight to achieve comparable exposures to adults and adolescents receiving the authorized dose. Given the similar course of COVID-19 disease, the authorization of bamlanivimab and etesevimab in younger pediatric patients, including neonates, is supported by safety and efficacy data in adolescents and adults, together with additional pharmacokinetic and safety data from the clinical trial in pediatric patients. The youngest participant in the pediatric clinical trial was ten months of age and weighed 8.6 kg [see Clinical Trials and Supporting Data for EUA (18.1)]

Bamlanivimab and Etesevimab COVID-19 Treatment Side Effects and Safety

There are limited clinical data available for bamlanivimab and etesevimab. Serious and unexpected adverse events may occur that have not been previously reported using bamlanivimab and etesevimab together. Serious hypersensitivity reactions, including anaphylaxis, have been observed with the administration of bamlanivimab and etesevimab. Adverse events reported in at least 1% of BLAZE-1 clinical trial participants on bamlanivimab 700 mg and placebo were Nausea (3% vs 4%), diarrhea (1% vs 5%), dizziness (3% vs 2%), Headache (3% vs 2%), Pruritus (2% vs 1%) and Vomiting (1% vs 3%).

There are insufficient data to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Therefore, Bamlanivimab and etesevimab should only be used during pregnancy if the potential benefit outweighs the potential risk for the mother and the fetus. And there are no available data on the presence of bamlanivimab or etesevimab in human or animal milk, the effects on the breastfed infant, or milk production. Breastfeeding individuals with COVID-19 should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19.

Anyone can submit a side effect report to VAERS, including parents and patients. And healthcare providers are required by law to report to VAERS.

Bamlanivimab and Etesevimab COVID-19 Antibody Treatment Guidelines

In light of recent National Institutes of Health clinical guidelines published on Dec. 30, 2021, and the significant variability in the prevalence of the Omicron Variant of Concern (VOC), all states and territories can continue to order bamlanivimab plus etesevimab from HHS based on allocated amounts for clinically appropriate use.

Eli Lilly says, 'If you've recently been diagnosed with COVID-19, you may have a new treatment option: bamlanivimab. The research shows that taking this drug may help limit the number of viruses in the body for certain people. This may help their symptoms improve sooner — and they may be less likely to need to go to the hospital. But bamlanivimab is a new drug that's still being studied, so there's a lot that scientists don't know about the benefits and risks. Together, you and your doctor can decide if this treatment is right for you.'

Bamlanivimab and COVID-19 Vaccination Benefits

A non-peer-reviewed study published on December 16, 2021, suggests a complementary role for COVID-19 mAbs with COVID-19 vaccines and that the benefit of receiving COVID-19 vaccination at the earliest opportunity outweighs the minimal effect on the endogenous immune response due to prior prophylactic COVID-19 mAb infusion. The effect of an anti-SARS-CoV-2 monoclonal antibody, bamlanivimab, on the endogenous immune response to COVID-19 vaccination study. All bamlanivimab and placebo study participants mounted a robust immune response following full COVID-19 vaccination, irrespective of age, risk category, and vaccine type, with any observed differences unlikely to be clinically meaningful.
