Sotrovimab |
GlaxoSmithKline (Xevudy) |
Intravenous infusion Must be Administered by a certified Health Care Provider |
The CDC found that sotrovimab is not active against the BA.2 Omicron subvariant. The FDA no longer authorizes sotrovimab to treat COVID-19 in the U.S. due to the Omicron BA.2 sub-variant becoming the dominant variant. The CDC reports that BA.2 now accounts for 72.2% of all COVID-19 cases with BA.1.1 accounting for most of the remaining cases. Recommended Dose: 500 mg per 8 mL of D5W or NS |
Recommend agent of choice Variants of concern: Alpha (S) Beta (S) Gama (S) Delta (S) Variants of interest: Epsilon (S) Theta (I) iota (S) Eta (S) Kappa (S) |
Provides intermediate coverage of omicron Does not cover the BA.2 sub variant |
Sotrovimab provides antibody coverage for most strains of COVID-19 (11) Dose adjustment is not needed (11) Sotrovimab is not authorized in patients that are hospitalized with COVID-19 (11) Patients should be monitored for 24 hrs after infusion for safety concerns (11) Refrigerate and allow to come to room temperature prior to administration (11) Do not shake upon administration (11) |

Usage was also granted for Mild - Moderate COVID-19 in Non Hospitalized patients, including neonates (4) Pediatric patients that are >12 kg are authorized to receive a treatment dose of 150/350 mg Bamlanivimab and etesevimab are not authorized for use in patients 2 years and older who are hospitalized due to COVID-19 (4) Bamlanivimab and etesevimab are not authorized for post-exposure prophylaxis of COVID-19 in geographic regions where exposure is likely to have been to a nonsusceptible SARS-CoV-2 variant (4) Recommended Dose: (700 mg/700 mg) per 20 mL NS or D5W |
Variants of concern: Alpha (S) Beta (I) Gama (I) Delta (I) Variants of Interest Kappa (S) Epsilon (S) Theta ( R ) Iota (P) Eta ( R ) |

(12) Prophylaxis for Post exposure 600 mg / 600 mg then 300 mg /300 mg once every 4 weeks. in Normal Saline mL (12) Casirivimab and imdevimab are not authorized for patients who are hospitalized or require supplemental oxygen (12) 600 mg / 600 mg in normal NS |
Varients of concern: Alpha (S) Beta (S) gamma (I) Delta (I) Variants of interest: Kappa (P) Epsilon (I) Mu (S) Iota (S) |
Not recommended by FDA due to reduced efficacy against omicron. (12) |
Combination of Casirivimab & Imdevimab is needed for efficacy (12) Should not be used if patient has hypertension. (12) No dose adjustments for Kidney function needed (12) Must be administered as soon as possible or within 10 days of a positive diagnosis (12) Must be refrigerated when not in use (12) Do not shake upon administration (12) Do not expose to light (12) Patients should be monitored for 24 hrs after infusion for safety concerns.

An additional 150 mg / 150 mg for patients that have already received an initial dose) should be considered (1) Must be refrigerated and protected from light (1) Should not be used if patient has hypersensitivity (1) Bring to room temperature upon administration (1) Do not shake upon administration (1) Evusheld is well tolerated and has shown no safety issues (1) |
Bebtelovimab |
Lilly |
Intravenous infusion Must be Administered by a certified HCP |
The FDA removed the EUA for bebtelovimab to treat COVID-19 because the antibody is not expected to neutralize Omicron subvariants BQ.1 and BQ.1.1. Bebetlovimab also is not approved for hospitalized patients. (3) Recommended dose: 175 mg / 2 mL of D5W or NS |
