• CAS 600 mg plus IMD 600 mg as a single IV infusion over 1 hour
• IV infusion is the preferred route of administration. However, when IV infusion is not feasible or would delay treatment, CAS 600 mg plus IMD 600 mg can be administered as 4 SUBQ injections (2.5 mL per injection) at 4 different sites. See the FDA EUA for detailed information.

Dose Recommended in FDA EUA for PEP for Individuals With Ongoing Exposure to SARS-CoV-2:

• After initial dose, repeat dosing of CAS 300 mg plus IMD 300 mg by SUBQ injections or IV infusion every 4 weeks for duration of ongoing exposure.

• Hypersensitivity, including anaphylaxis and infusion-related reactions
• These AEs were observed in multiple trials in which participants received CAS 600 mg plus IMD 600 mg or higher doses of each drug.
• Injection site reactions, including ecchymosis and erythema, in clinical trial participants who received CAS plus IMD as SUBQ injections

• Only for administration in health care settings by qualified health care providers who have immediate access to emergency medical services and medications to treat severe infusion reactions.
• Monitor during IV infusion or SUBQ injections and for ≥1 hour after infusion or injections are completed.

• Drug-drug interactions are unlikely between CAS plus IMD and medications that are renally excreted or that are CYP substrates, inhibitors, or inducers.

Availability:

• Distribution of CAS plus IMD has paused because the Omicron VOC has markedly reduced in vitro susceptibility to CAS plus IMD, and this regimen is not expected to provide clinical benefit.
• HHS Public Health Emergency updates on the distribution of CAS plus IMD are available.
• A list of clinical trials is available: Casirivimab Plus Imdevimab

Dose Recommended in FDA EUA for Treatment of COVID-19 in Adults and Pediatric Patients Aged ≥12 Years and Weighing ≥40 kg:

• SOT 500 mg as an IV infusion over 15 minutes for 50 mL bag or over 30 minutes for 100 mL bag

• Rash
• Diarrhea
• Hypersensitivity, including anaphylaxis and infusion-related reactions

• Only for administration in health care settings by qualified health care providers who have immediate access to emergency medical services and medications to treat severe infusion reactions.
• Monitor during IV infusion and for ≥1 hour after infusion is completed.

• Drug-drug interactions are unlikely between SOT and medications that are renally excreted or that are CYP substrates, inhibitors, or inducers.

Availability:

• Distribution of SOT has paused because the Omicron BA.2 subvariant has markedly reduced susceptibility to SOT, and SOT is not expected to provide clinical benefit.
• HHS Public Health Emergency updates on the distribution of SOT are available.
• A list of clinical trials is available: Sotrovimab

Doses Recommended in EUA for PrEP of COVID-19 in Adults and Pediatric Patients Aged ≥12 Years and Weighing ≥40 kg:

• TIX 300 mg plus CIL 300 mg as 2 consecutive 3 mL IM injections

For patients who previously received a dose of TIX 150 mg plus CIL 150 mg, administer a second dose per the following criteria as soon as possible:

• If the initial dose was ≤3 months ago, the second dose should be TIX 150 mg plus CIL 150 mg.
• If the initial dose was >3 months ago, the second dose should be TIX 300 mg plus CIL 300 mg.

• Hypersensitivity, including anaphylaxis and injection-related reactions
• In 1 clinical trial, cardiac events were reported in participants with cardiac risk factors (0.6% in TIX plus CIL arm vs. 0.2% in placebo arm).

• Use with caution in individuals with thrombocytopenia or any coagulation disorder.
• Monitor for ≥1 hour after injection.

• If a person has received a COVID-19 vaccine, TIX plus CIL should be administered ≥2 weeks after vaccination.
• Drug-drug interactions are unlikely between TIX plus CIL and medications that are renally excreted or that are CYP substrates, inhibitors, or inducers.

• Under the FDA EUA, TIX plus CIL for PrEP of COVID-19 is available for certain patients at high risk of infection. See Prevention of SARS-CoV-2 Infection for more information.²
• A list of clinical trials is available: Tixagevimab Plus Cilgavimab

Dose Recommended in FDA EUA for Treatment of COVID-19:

• Per the EUA, consider starting clinical dosing with 1 high-titer COVID-19 CP unit (about 200 mL), with administration of additional CP units based on the prescribing provider’s medical judgment and the patient’s clinical response.

• TRALI
• TACO
• Allergic reactions
• Anaphylactic reactions
• Febrile nonhemolytic reactions
• Hemolytic reactions
• Hypothermia
• Metabolic complications
• Transfusion-transmitted infections³
• Thrombotic events
• Theoretical risk of antibody-mediated enhancement of infection and suppressed long-term immunity

• Before administering CP to patients with a history of severe allergic or anaphylactic transfusion reactions, the Panel recommends consulting a transfusion medicine specialist who is associated with the hospital blood bank.
• Monitor for transfusion-related reactions.
• Monitor vital signs at baseline and during and after transfusion.

• Drug products should not be added to the IV infusion line for the blood product.

• The decision to use COVID-19 CP for the treatment of COVID-19 in patients aged <18 years should be based on an individualized assessment of risk and benefit.⁴
• In patients with impaired cardiac function and heart failure, it may be necessary to reduce the CP volume or decrease the transfusion rate.

• Under the FDA EUA, high-titer COVID-19 CP is available for hospitalized patients with COVID-19.⁴ See Convalescent Plasma.
• A list of clinical trials is available: COVID-19 Convalescent Plasma 

Dose in Clinical Trials for Treatment of COVID-19:

• Dose varies by clinical trial.

• TRALI
• TACO
• Allergic reactions
• Antibody-mediated enhancement of infection
• RBC alloimmunization
• Transfusion-transmitted infections³

• Monitor for transfusion-related reactions.
• Monitor vital signs at baseline and during and after transfusion.

• Drug products should not be added to the IV infusion line for the blood product.

• A list of clinical trials is available: SARS-CoV-2 Immunoglobulin
