Lilly's neutralizing antibody bamlanivimab (LY-CoV555) receives interim authorization from Health Canada as a treatment for COVID-19
Health Canada today granted authorization, under the Interim Order Respecting the Importation, Sale and Advertising of Drugs for Use in Relation to COVID-19, for the use of bamlanivimab (LY-CoV-555) as a treatment of adults and pediatric patients 12 years of age or older with mild to moderate COVID-19 who weigh at least 40 kg and are at high risk of progressing to severe COVID-19 illness and/or hospitalization, Eli Lilly and Company (NYSE: LLY) announced. This authorization, the second authorization around the world for bamlanivimab, is based on data from BLAZE-1, a randomized, double-blind placebo-controlled phase 2 study in patients with recently diagnosed, mild to moderate COVID-19.
"This authorization in Canada furthers our goal of making bamlanivimab available to patients who need it around the world and is evidence of the strong collaboration between industry and governments to get COVID-19 medicines to people as quickly as possible," said David A. Ricks, Lilly's chairman and CEO. "We are proud that this treatment, which was developed in partnership with the Canadian biotech company AbCellera, will soon be available to help people in Canada combat this pandemic."
In BLAZE-1, patients treated with bamlanivimab showed reduced viral load and rates of symptoms and hospitalization. In BLAZE-1, frequency and types of adverse events were similar between bamlanivimab and placebo, with the majority being mild to moderate in severity. Infusion reactions and other allergic hypersensitivity events have been reported.
"As a Canadian company, we are proud to contribute to the global fight against COVID-19 and hope our efforts will help people in Canada and around the world in the face of this medical emergency," said Carl Hansen, Ph.D., CEO of AbCellera. "We applaud Lilly for bringing bamlanivimab to patients at record speed and its commitment to ensure treatment access for patients with high unmet needs, no matter where they live."
Global manufacturing, supply and regulatory updates
Lilly has a robust, global supply chain in place and began large-scale manufacturing of bamlanivimab at risk earlier this year. Lilly anticipates manufacturing up to one million doses of bamlanivimab 700 mg by the end of 2020, for use around the world through early next year.
On November 9th, the U.S. Food and Drug Administration (FDA) granted Emergency Use Authorization (EUA) for bamlanivimab 700 mg. In the U.S., bamlanivimab is authorized for the treatment of mild to moderate COVID-19 in adults and pediatric patients 12 years and older weighing at least 40 kg with a positive COVID-19 test, who are at high risk for progressing to severe COVID-19 and/or hospitalization.
Lilly is in discussions with global regulators to make bamlanivimab available around the world. The company is focused on areas with the highest disease burden and pursuing authorization in countries such as India, Brazil, Russia and across Europe. Global allocation will be made based on Lilly's guiding principles that aim to ensure access for patients with high unmet need, no matter where they live.
About bamlanivimab
Bamlanivimab is a recombinant, neutralizing human IgG1 monoclonal antibody (mAb) directed against the spike protein of SARS-CoV-2. It is designed to block viral attachment and entry into human cells, thus neutralizing the virus, potentially treating COVID-19. Bamlanivimab emerged from the collaboration between Lilly and AbCellera to create antibody therapies for the prevention and treatment of COVID-19. Lilly scientists rapidly developed the antibody in less than three months after it was discovered by AbCellera and the scientists at the National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center. It was identified from a blood sample taken from one of the first U.S. patients who recovered from COVID-19.
Lilly has successfully completed a Phase 1 study of bamlanivimab in hospitalized patients with COVID-19 (NCT04411628). A Phase 2 study in people recently diagnosed with COVID-19 in the ambulatory setting (BLAZE-1, NCT04427501) is ongoing. A Phase 3 study of bamlanivimab for the prevention of COVID-19 in residents and staff at long-term care facilities (BLAZE-2, NCT04497987) is also ongoing. In addition, bamlanivimab is being tested in the National Institutes of Health-led ACTIV-2 study in ambulatory COVID-19 patients.
About BLAZE-1
BLAZE-1 (NCT04427501) is a randomized, double-blind, placebo-controlled Phase 2 study designed to assess the efficacy and safety of bamlanivimab alone or in combination with a second antibody for the treatment of symptomatic COVID-19 in the outpatient setting. To be eligible, patients were required to have mild or moderate symptoms of COVID-19 as well as a positive SARS-CoV-2 test based on a sample collected no more than three days prior to drug infusion.
The monotherapy arms of the trial enrolled mild to moderate recently diagnosed COVID-19 patients, studying three doses of bamlanivimab (700 mg, 2800 mg, and 7000 mg) versus placebo. The primary outcome measure for the completed arms of the BLAZE-1 trial was change from baseline to day 11 in SARS-CoV-2 viral load. Additional endpoints include the percentage of participants who experience COVID-related hospitalization, ER visit or death from baseline through day 29, as well as safety.
The study is ongoing with additional treatment arms. Across all treatment arms, the trial will enroll over 800 participants.
Data from the monotherapy arms of BLAZE-1 were published in the New England Journal of Medicine.
