Bamlanivimab COVID-19 Antibody Treatment Description

Eli Lilly's Bamlanivimab (LY-CoV555) neutralizing IgG1 monoclonal antibody (mAb) 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. 

Bamlanivimab emerged from the collaboration between Lilly and AbCellera to create antibody therapies to prevent and treat COVID-19. Lilly scientists rapidly developed the antibody in less than three months after being discovered by AbCellera and tested by the NIAID Vaccine Research Center scientists.

Bamlanivimab is authorized in the USA by the U.S. FDA to treat mild to moderate COVID-19 in adults and pediatric patients 12 years and older with a positive COVID-19 test, who are at high risk for progressing to severe COVID-19 and/or hospitalization. Therefore, Bamlanivimab should be administered as soon as possible after a positive COVID-19 test and within ten days of symptom onset.

On April 16, 2021, Lilly requested Bamlanivimab's single-use authorization in the USA to be withdrawn. In addition to Bamlanivimab, a second Lilly antibody, LY-CoV016, which binds a different epitope in the SARS-CoV-2 spike region, has been added to the BLAZE-1 clinical trial. Etesevimab (LY-CoV016, also known as JS016) is a recombinant fully human monoclonal neutralizing antibody, which specifically binds to the SARS-CoV-2 surface spike protein receptor-binding domain with 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.

On June 25, 2021, the Assistant Secretary for Preparedness and Response (ASPR) announced, 'it is immediately pausing all distribution of bamlanivimab and etesevimab together and etesevimab alone (to pair with the existing supply of bamlanivimab at a facility for use under EUA 094) on a national basis until further notice.

The NEJM published an Orginal Article on July 14, 2021, that concluded, 'Among high-risk ambulatory patients, bamlanivimab plus etesevimab led to a lower incidence of Covid-19–related hospitalization and death than did placebo and accelerated the decline in the SARS-CoV-2 viral load.' And the U.S. NIH published updated Anti-SARS-CoV-2 Monoclonal Antibodies guidance on August 4, 2021.

On August 27, 2021, a US Public Health Emergency notice issued bamlanivimab and etesevimab administered together are currently authorized for use in the states of Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, New Hampshire, Michigan, Minnesota, Missouri, Montana, Nebraska, North Dakota, Ohio, Rhode Island, South Dakota, Utah, Vermont, Wisconsin, and Wyoming. Therefore, effective today, ASPR will resume distribution of bamlanivimab and etesevimab together and etesevimab alone (to pair with the existing supply of bamlanivimab at a facility for use under EUA 094 to these states.

The U.S. FDA confirmed on August 27, 2021, the changes to the authorized use of the monoclonal antibodies bamlanivimab and etesevimab, administered together. 

On September 15, 2021, the U.S. NIH published COVID-19 Treatment Guidelines Panel’s Statement on Bamlanivimab 700 mg Plus Etesevimab 1,400 mg for the Treatment of Mild to Moderate COVID-19 in Nonhospitalized Patients with intravenous infusion in regions where the combined frequency of potentially resistant SARS-CoV-2 virus variants is low.

The U.S. FDA expanded the EUA on September 16, 2021, for bamlanivimab 700 mg and etesevimab 1400 mg administered together to include post-exposure prophylaxis in certain individuals for the prevention of SARS-CoV-2 infection. Daniel Skovronsky, M.D., Ph.D., Lilly's chief scientific and medical officer, and president of Lilly Research Laboratories, said in a related press release, "We're pleased that this expansion will help us provide antibody therapies as post-exposure prophylaxis to help prevent the spread of COVID-19 to some of the most at-risk individuals in the U.S." The expanded EUA is based on data from BLAZE-2 (NCT04497987), a study conducted in partnership with the U.S. NIAID.

Patients and physicians can visit the NICA Infusion Center Locator or the HHS Therapeutics Distribution locator to find a potential therapy location.

Etesevimab Monoclonal Neutralizing Antibody

Etesevimab (LY-CoV016, JS016) is a recombinant fully human monoclonal neutralizing antibody. It specifically binds 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. The U.S. FDA published a revised Fact Sheet on March 20, 2021.

Eli Lilly licensed etesevimab from Junshi Biosciences after jointly developed by Junshi Biosciences and the Institute of Microbiology, Chinese Academy of Science. 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.

 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 COVID-19 Antibody Treatment History 

On November 9, 2020, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for bamlanivimab and etesevimab administered together. They are authorized to treat mild to moderate COVID-19 in adult patients and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing and who are at high risk for progressing to severe COVID-19 and/or hospitalization. The issuance of a EUA does not constitute FDA approval of a product. The COVID-19 Treatment Guidelines Panel reviewed the available evidence from the published data on bamlanivimab for the treatment for COVID-19 and the FDA fact sheet that supported the EUA, said the NIH.

The company announced a new purchase agreement with the US government on December 2, 2020, for $812.5 million. The bamlanivimab doses will be delivered through January 31, 2021, with at least 350,000 additional doses given in December 2020. 

On January 26, 2021, Lilly announced new data show treatment with the neutralizing antibodies bamlanivimab (LY-CoV555) and etesevimab (LY-CoV016) reduces the risk of COVID-19 hospitalizations and death by 70%. "These exciting results, which replicate positive Phase 2 data in a much larger set of patients, add valuable clinical evidence about the role neutralizing antibodies can play in fighting this pandemic. While the preliminary nature of Phase 2 results from COVID-19 neutralizing monoclonal antibodies may have limited acceptance of treatment, these Phase 3 data further strengthen the available evidence," said Daniel Skovronsky, M.D., Ph.D., Lilly's chief scientific officer and president of Lilly Research Laboratories, in a press statement.

The U.S. FDA announced a EUA granting on February 9, 2021, for Lilly's investigational bamlanivimab (LY-CoV555) 700 mg and etesevimab (LY-CoV016) 1400 mg together. This therapy is authorized to treat mild to moderate COVID-19 in patients aged 12 and older who are at high risk for progressing to severe COVID-19 and/or hospitalization. This EUA states Bamlanivimab and etesevimab should be administered together via a single intravenous infusion as soon as possible after a positive COVID-19 test and within ten days of symptom onset. The FDA has also authorized infusion times for bamlanivimab alone and bamlanivimab and etesevimab together to be as short as 16 or 21 minutes, respectively – a significant reduction from the previously authorized time of 60 minutes.

On March 11, 2021, the EMA announced its review process had launched.

On May 11, 2021, the US Centers for Medicare & Medicaid Service (CMS) confirmed the investigational monoclonal antibody therapies are available under FDA emergency use authorization (EUA): Bamlanivimab and etesevimab, administered together (EUA issued February 9, 2021). The FDA authorized the use of these monoclonal antibody therapies to treat mild-to-moderate COVID-19 in adults and pediatric patients when both of these apply: the patient has a positive COVID-19 test result, and the patient is at high risk for progressing to severe COVID-19, hospitalization, or both.

Bamlanivimab COVID-19 Antibody Treatment Indication

Bamlanivimab (LY-CoV555) is indicated to prevent or mitigate the progression of COVID-19 infection caused by the SARS-CoV-2 coronavirus. As of November 9, 2020, Bamlanivimab was authorized for patients with positive results of direct SARS-CoV-2 viral testing who are 12 years of age and older, weighing at least 40 kilograms (about 88 pounds), and who are at high risk for progressing to severe COVID-19 and/or hospitalization. Bamlanivimab should be administered as soon as possible after a positive COVID-19 test and within ten days of symptom onset, says Lilly.

The U.S. FDA EUA includes 65 years of age or older or certain chronic medical conditions. Bamlanivimab is not authorized for hospitalized patients due to COVID-19 or requires oxygen therapy due to COVID-19. Healthcare providers should review the Fact Sheet for information on the authorized use of bamlanivimab and mandatory requirements of the EUA. In August 2021, the FDA published an updated Fact Sheet.

AbCellera (Nasdaq: ABCL) announced on September 16, 2021, the U.S. FDA had expanded the EUA for bamlanivimab (LY-CoV555) 700 mg administered with etesevimab (LY-CoV016) 1400 mg to include post-exposure prophylaxis to prevent SARS-CoV-2 infection or symptomatic COVID-19. The neutralizing antibodies can now be used together to treat high-risk individuals 12 years of age and older who have not been fully vaccinated against COVID-19 or are not expected to mount an adequate immune response to complete vaccination, and have been exposed to someone infected with SARS-CoV-2 or who are at high risk of exposure in an institutional setting, including a nursing home or prison.

Bamlanivimab COVID-19 Treatment Side Effects

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%).

Bamlanivimab COVID-19 Antibody Treatment Safety Information

The U.S. FDA has not Approved Bamlanivimab and etesevimab together and bamlanivimab alone FDA for any use. It is unknown if bamlanivimab and etesevimab together or bamlanivimab alone are safe and effective for the treatment of COVID-19. There are limited clinical data available for bamlanivimab. Serious and unexpected adverse events may occur that have not been previously reported with bamlanivimab use. Infusion-related reactions have been observed with the administration of bamlanivimab.

There are insufficient data on the use of bamlanivimab during pregnancy. Therefore, Bamlanivimab should only be used during pregnancy if the potential benefit outweighs the mother and fetus's potential risk. In addition, there are no available data on the presence of bamlanivimab in human or animal milk, the effects on the breastfed infant, or the effects on milk production. Therefore, breastfeeding individuals with COVID-19 should follow practices according to clinical guidelines to avoid exposing the infant to COVID-19.

On September 9, 2021, the EMA published COVID-19 treatment: Under Evaluation that is not Authorised specifically for patients with COVID-19.

Bamlanivimab COVID-19 Antibody Treatment Guidelines

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.'

The revised NIH COVID-19 Treatment Guidelines Panel’s Statement on the Emergency Use Authorization of Bamlanivimab for the Treatment of COVID-19 indicates the optimal dose of bamlanivimab plus etesevimab for the treatment of COVID-19 has not yet been established, and the dose currently recommended by the EUA may be revised as data from clinical trials emerge.

On August 20, 2021, the U.S. FDA and ASPR announced the Authorization of an extension to the shelf-life from 12 months to 18 months for the refrigerated Eli Lilly monoclonal antibody, bamlanivimab, which is currently authorized for emergency use only when administered together with etesevimab.  As a result of this extension, unopened vials of bamlanivimab, injection, 700 mg/20 mL, should be stored under refrigerated temperature at 2°C to 8°C (36°F to 46°F), and maybe stored for an additional 6 months from the labeled date of expiry.

Bamlanivimab COVID-19 Antibody Allocations

A current list of countries with a purchase agreement and regulatory authorization is found on this Eli Lilly webpage. The quantity listed is approximate, based on medical allocations, and – as noted in the process – the actual volume shipped could be more or less, depending on what the country accepted for purchase and any additional quantities that were available for purchase if another country did not accept its full allocation.

As of August 27, 2021, the U.S. FDA posted a list of states, territories, and U.S. jurisdictions in which bamlanivimab and etesevimab administered together are currently authorized, and a list of states, territories, and U.S. jurisdictions in which bamlanivimab and etesevimab, administered together, are not currently authorized and will periodically update both lists as new data and information become available. The FDA will determine this considering current variant frequency data, trends in variant frequency over time, and the precision of the estimates and information regarding emerging variants of concern.

The U.S. HHS announced on September 3, 2021, it is immediately implementing the following changes to help promote optimal and equitable use of the available supply of monoclonal antibodies while we continue efforts to procure additional products: Limiting immediate orders and shipment only to administration sites with HHSProtect accounts and current utilization reporting; Reviewing all orders for alignment with utilization, currently estimated at 70% of orders.
