- Abstract
Introduction: In November 2020, the FDA issued an emergency use authorization (EUA) for monoclonal antibody (mAb) therapy in patients with mild-to-moderate COVID-19 at high risk for disease progression., Methods: We retrospectively reviewed 38 adult hematology patients who received mAbs from 11/2020 to 2/2021., Results: Thirty (79%) patients received bamlanivimab and 8 (21%) casirivimab-imdevimab. Four (11%) patients were hospitalized due to COVID-19, two (5%) progressed to severe disease and one patient (3%) died within 30 days from COVID-19 disease. Most patients (n = 34, 89%) ultimately tested negative for SARS-CoV-2, with 34% (n = 13) clearing the virus within 14 days after mAb infusion. The median time to clearance of viral shedding was 25.5 days (range: 7-138). After mAb infusion, most patients with hematological malignancies (HM) (n = 10/15; 67%) resumed therapy for underlying disease with a median delay of 21.5 days (range: 12-42). We observed a significant difference in hospitalization among patients who received a HCT versus non-HCT (0% n = 0/26 and 36% n = 4/11, respectively; p < 0.01)., Conclusions: This study demonstrates that SARS-CoV-2 specific mAb was safe and may reduce hospitalization compared to what is reported in malignant hematology patients at high risk for disease progression. Our HCT cohort patients had less hospitalization rate compared with HM cohort patients., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)
