COVID Pre-exposure prophylaxis (PrEP) Overview

On December 08, 2021, the Food and Drug Administration (FDA) granted an Emergency Use Authorization (EUA) for AstraZeneca’s Evusheld (tixagevimab co-packaged with cilgavimab and administered together) for the pre-exposure prophylaxis (prevention) of COVID-19 in certain adults and pediatric individuals (12 years of age and older and weighing at least 40 kilograms.) This product is only authorized for use among individuals who are not currently infected with SARS-CoV-2 virus and have not recently been exposed to an individual infected with SARS-CoV-2. The EUA requires that individuals either have:

  • Moderate to severely compromised immune system due to a medical condition or receipt of immunosuppressive medications or treatments and may not mount an adequate immune response to COVID-19 vaccination OR
  • A history of severe adverse reactions to a COVID-19 vaccine and/or component(s) where administration of the vaccine is not recommended.

Evusheld is not authorized for individuals for the treatment of COVID-19 or for post-exposure prevention of COVID-19. Pre-exposure prophylaxis with Evusheld is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended, including those with moderate to severe immunocompromising conditions. For individuals who have received a COVID-19 vaccine, Evusheld should be administered at least two weeks after vaccination. For additional information see: FACT SHEET FOR HEALTHCARE PROVIDERS: EMERGENCY USE AUTHORIZATION FOR EVUSHELD™ (tixagevimab co-packaged with cilgavimab) (fda.gov)

Frequently Asked Questions

Please read the Frequently Asked Questions (FAQ) so you can help protect yourself, your family, your friends, and your community.

I am interested in providing COVID PrEP at my clinic. How do I become a COVID PrEP provider?

Please contact COVID.Therapeutics@state.nm.us to receive registration information.

What patient screening is recommended for COVID PrEP?

RECOMMENDED SCREENING FOR PATIENT WITH A CONTRAINDICATION TO VACCINE

Clear documentation that vaccination is contraindicated

The CDC considers a history of the following to be a contraindication to vaccination with COVID-19 vaccines:

1. Severe allergic reaction (e.g., anaphylaxis) after a previous dose or to a component of the COVID-19 vaccine

a. A patient with an allergic reaction to a mRNA vaccine may be able to receive Janssen COVID-19 vaccine and vice versa.

2. Known diagnosed allergy to a component of the COVID-19 vaccine.

 Please refer to the CDC clinical considerations for guidance regarding contraindications and precautions. https://www.cdc.gov/vaccines/covid-19/clinical-considerations/covid-19-vaccines-us.html#Contraindications

 RECOMMENDED SCREENING FOR IMMUNOCOMPROMISED PATIENTS

 This is a recommendation to assist providers in prioritizing patients. The following laboratory screening is not a requirement.

 Negative IgG SARS-CoV-2 antibody assay following a full course of vaccination

If a laboratory offers multiple tests for COVID-19 antibodies, testing should be performed using the test for IgG spike or RBD antibodies rather than for nucleocapsid antibodies, since vaccines do not contain nucleocapsid antibody.

Negative IgG SARS-CoV-2 antibody screening is not required.

 The appropriate test include: TriCore test number COVIGG, Labcorp test number 164055 and Quest test number 34499.

Can I give Evusheld as post-exposure prophylaxis?

No, this product is only authorized for use among individuals who are not currently infected with SARS-CoV-2 virus and have not recently been exposed to an individual infected with SARS-CoV-2.

I am not an Evusheld provider. Where may I refer my patient for treatment?

A list of Evusheld providers can be found at cv.nmhealth.org/treatments.

 You may also contact COVID.Therapeutics@state.nm.us if you are interested in becoming an Evusheld provider.

What is the efficacy of Evusheld against the Omicron variant?

Preliminary data for the neutralizing activities of Tixagevimab/Cilgavimab against the Omicron (B.1.1.529) variant of concern are available. In vitro testing of Tixagevimab/Cilgavimab for neutralization of a pseudovirus expressing the spike protein representative of the predominant lineage of the SARS-CoV-2 Omicron variant has demonstrated a 132 to 183-fold reduction of potency (IC50) compared with its activity against the D614G variant. A 12 to 30-fold reduction in potency was demonstrated using authentic Omicron virus.

The clinical significance of the reduced in vitro potency of Tixagevimab/Cilgavimab against the Omicron variant is unknown at this time.

COVID PrEP Required Reporting

Reporting of Evusheld Inventory and Utilization

  • All sites are required to report their inventory and utilization on HPOP. The data impacts the states allocation from the federal government. The data is also used to ensure equitable allocation between facilities. 

Reporting Adverse Events

COVID PrEP Distribution

Evusheld, is currently under allocation. The state is currently receiving a very limited number of doses. The federal government allocates a portion of the available supply to each state on a bi-weekly cycle. https://www.phe.gov/emergency/events/COVID19/therapeutics/distribution/Pages/data-tables.aspx 

New Mexico Department of Health allocates product to participating facilities. Shipments are received by facilities once every two weeks.
