A Study of LY3819253 (LY-CoV555) in Participants Hospitalized for COVID-19

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04411628

Brief Summary:
The purpose of this study is to test the safety and tolerability of LY3819253 when it is given by injection into a vein to participants hospitalized with COVID-19. Blood tests will be done to check how much LY3819253 is in the bloodstream and how long the body takes to eliminate it. Participation could last about 8 weeks and may include up to 15 visits in the hospital or the home.

Arm Intervention/treatment
Experimental: LY3819253
Participants received single doses of 700 milligrams (mg), 2800 mg or 7000 mg LY3819253 administered as intravenous infusion.
Drug: LY3819253
Administered IV.
Other Names:
  • LY-CoV555
  • Bamlanivimab

Placebo Comparator: Placebo
Participants received single dose of Placebo as intravenous infusion.
Drug: Placebo
Administered IV.

Primary Outcome Measures :
  1. Number of Participants With One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration [ Time Frame: Baseline through Day 60 ]
    An SAE is any adverse event that results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. The number of participants with 1 or more SAEs considered by the investigator to be related to study drug administration is reported. A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, were reported in the Reported Adverse Events module.

Secondary Outcome Measures :
  1. Pharmacokinetics (PK): Mean Concentration of LY3819253 on Day 29 [ Time Frame: Day 29 ]
    Pharmacokinetics (PK): Mean Concentration of LY3819253 on Day 29.

  2. Pharmacodynamics (PD): Change From Baseline to Day 29 in Viral Load [ Time Frame: Baseline, Day 29 ]
    Pharmacodynamics (PD): Change from Baseline to Day 29 in Viral Load.

  3. Pharmacodynamics (PD): SARS-CoV-2 Viral Load AUC [ Time Frame: Day 1 pre-dose, Days 3, 7, 11, 15, 22, 29 post dose ]
    The SARS-CoV-2 viral load was derived from the cycle time (CT) values using a polymerase chain reaction (PCR) assay. Higher CT values indicate a lower viral load.

  4. Pharmacodynamics (PD): Time to SARS-CoV-2 Clearance [ Time Frame: Day 1 pre-dose, Days 3, 7, 11, 15, 22, 29 post dose ]
    Pharmacodynamics (PD): Time to SARS-CoV-2 clearance.
