Monoclonal Antibody Therapy at Montefiore

If you have COVID-19, you may be at high-risk for severe symptoms. Talk to your doctor to see if you are eligible for monoclonal antibody treatment, based on your age, the length of your symptoms, and existing medical conditions.

What is monoclonal antibody therapy?
Monoclonal Antibody

Monoclonal antibodies are created in a lab and function like naturally occurring antibodies, fighting infections before they spread. Studies show that when monoclonal antibodies are given intravenously to high-risk people diagnosed early with COVID-19, it can prevent them from experiencing severe symptoms that lead to hospitalizations.

Montefiore has been offering monoclonal antibody treatment to patients since December 2020 in our Montefiore’s Bronx Emergency Departments. Since then, Montefiore opened an infusion suite – now the main location for this therapy – and is partnering with local nursing homes to treat their residents.

There are multiple monoclonal antibody therapies available, which have been authorized by the Food and Drug Administration. We are now offering the Regeneron combination of Casirivimab and Imdevimab, which has also proved effective in treating COVID-19 variances.

How is monoclonal antibody therapy given?

The monoclonal antibody treatment is given using IV therapy, administered through a vein in the arm, for about an hour. Patients are evaluated by a nurse practitioner and then monitored for any allergic reactions, which are extremely rare. The appointment takes about three hours to complete; afterward, patients receive a follow-up phone visit. A few weeks later, a telehealth appointment is completed with an infectious disease doctor who reviews recovery and symptoms.
