“Fair and equitable” distribution planned
During phase 1 of distribution, the agent will first be allocated to hospitals and hospital-affiliated locations only, John Redd, MD, MPH, chief medical officer, Office of the Assistant Secretary for Preparedness and Response at HHS, said at the press conference.
During phase 2, “there will be expanded distribution to outpatient sites,” he said. In an effort to keep the process transparent, a new website features the latest updates on the distribution of bamlanivimab.
Allocation will be based on two factors: the number of new cases reported in a state or territory in the prior 7 days, and rates of COVID-19 hospitalization during the same period.
Asked why the government would determine distribution of the antibody on the basis of the number of hospitalized patients when the indication includes prevention of admission, Woodcock replied that hospitalization is a surrogate measure that can reflect risk factors in a particular state population, such as obesity, diabetes, or the proportion of older people.
Furthermore, the confirmed cases are a “leading indicator,” she said, that can help identify a steep rise in COVID-19 cases that could indicate more hospitalizations are likely soon. “We don’t want to miss that.”
Data underlying the EUA decision
A decrease in hospitalizations or emergency department visits within 28 days of treatment in preclinical studies was “the most important evidence that bamlanivimab may be effective,” the agency noted in the press release announcing the EUA. Among patients at high risk for progression, 3% required such interventions, compared with 10% of placebo-treated patients.
Potential side effects of bamlanivimab include anaphylaxis, infusion-related reactions, nausea, diarrhea, dizziness, headache, itching, and vomiting.
“As illustrated by today’s action, the FDA remains committed to expediting the development and availability of potential COVID-19 treatments and providing sick patients timely access to new therapies where appropriate,” FDA Commissioner Stephen M. Hahn, MD, said in the news release.
Healthcare providers can download a detailed FDA fact sheet on the EUA for bamlanivimab, which includes dosing instructions.
