5.3.6 nMABs and other antiviral drugs

Neutralising monoclonal antibodies (nMABs) and antivirals for COVID-19 for non-hospitalised patients

Antivirals or neutralising monoclonal antibodies (nMABs) are recommended for non-hospitalised patients with COVID-19 who are considered to be at highest risk of progression to severe disease, hospital admission or death. Eligibility criteria for treatment are outlined in a national clinical commissioning policy. The treatment options from 10 February 2022 are:

  • First-line: Paxlovid (oral antiviral) OR sotrovimab (nMAB given by intravenous infusion)
  • Second-line: Remdesivir (antiviral given by intravenous infusion)
  • Third-line: Molnupiravir (oral antiviral)

GPs must not prescribe nMABs or antivirals for COVID-19. Community pharmacies and dispensing practices will not have access to stocks of these medicines

Access to these medicines for non-hospitalised patients is through the local COVID Medicine Delivery Units (CMDU).

Referral to a CMDU
See the clinical referral guidelines below for information on which patients require referral to a CMDU and how to refer:

Please do not email referrals to DRSS (as previously advised) as this may introduce a delay in the referral reaching the service.

Where will patients receive nMABs or antivirals treatment?
nMABs are administered intravenously so a patient will need to safely travel to a CMDU site. If the CMDU decides that an antiviral is the most appropriate treatment option, these will be dropped off to a patient’s home, either via a friend or family member of the patient, or via a delivery service.

PANORAMIC study
Oral antivirals will be made available to a wider cohort of at-risk patients through a national study known as the PANORAMIC study. Further information is available here: PANORAMICtrial. Patients eligible for nMABs or oral antivirals under the UK interim commissioning policies must first be referred to the CMDU.
