Study summary

This is a study of immunocompromised individuals who have received or plan to receive a drug called EVUSHELD. This study is looking at any serious adverse events that might happen after receiving EVUSHELD, the levels of EVUSHELD in participant's blood, blood antibody levels, neutralizing antibodies against SARS-CoV-2 (the virus that causes COVID-19), and other blood responses related to the immune system and COVID-19. Investigators are collecting blood and may also collect other samples such as nose swabs, oral swabs, or saliva.

Read the detailed description

This is a prospective study of 500 immunocompromised participants at UPMC health system. EVUSHELD will be given according to the EUA in the United States as a part of standard of care by the patient's health care provider. Patients who receive intramuscular EVUSHELD as standard of care will be enrolled and followed for 12-months. The target sample size is 500 immunocompromised individuals; serum concentrations of AZD7442 will be obtained in all patients at the 6 (or at enrollment if the time point has passed) and 12 month timepoints.

What researchers measure

Primary outcomes

  1. Concentration of AZD7442 in serum over time [ENROLLMENT, 6 MONTHS, 12 MONTHS] Concentration of AZD7442 in serum over time [ENROLLMENT, 6 MONTHS, 12 MONTHS] Concentration of AZD7442 in serum over time [ENROLLMENT, 6 MONTHS, 12 MONTHS]

    The primary objective of PrEP C-19 is to measure AZD7442 serum concentration levels by blood draws at 6 months (or at enrollment if the time point has passed) and 12 months after IM administration of EVUSHELD.

    Time frame: 12-months

    Collected at enrollment and 1, 3, 6, 9, and 12 months

    Time frame: 12-months

  3. Assessment of T-cell responses using an ELISPOT assay

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2022 to primary completion in Jan 2024, 18 months.

Of 1,625 non-industry observational studies under COVID-19, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 29. This study's 18 months is above that.

Counting every sponsor, half of 1,750 studies reached it within 13 months; a quarter within 5 and three quarters within 29.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 15, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
