Study Endpoints

Primary Endpoints

Number of participants with any treatment-emergent adverse events (AEs)
Day 1 through 36 weeks

A treatment-emergent AE is any AE with an onset date on or after the investigational product start date and no later than 36 weeks after permanent discontinuation of the investigational product.

Number of participants with any serious AEs (SAEs)
Day 1 through 36 weeks

An SAE is any life-threatening event or one that results in hospitalization, significant disability/incapacity, death or congenital anomaly/birth defect.

Number of participants with any local site reactogenicity event after first dose
Day 1 through 14 days after first dose

Signs and symptoms will be captured at the injection site (e.g., pain/tenderness, swelling, redness and induration) through self-assessment via participant diaries and in-person clinical assessments.

Number of participants with any local site reactogenicity event after second dose
Day 1 through 14 days after second dose

Signs and symptoms will be captured at the injection site (e.g., pain/tenderness, swelling, redness and induration) through self-assessment via participant diaries and in-person clinical assessments.

Number of participants with any systemic reactogenicity event after first dose
Day 1 through 14 days after first dose

Systemic signs and symptoms (fever, headache, fatigue, arthralgia, myalgia, malaise, nausea, vomiting or chills) through self-assessment via participant diaries and in-person clinical assessments.

Number of participants with any systemic reactogenicity event after second dose
Day 1 through 14 days after second dose

Systemic signs and symptoms (fever, headache, fatigue, arthralgia, myalgia, malaise, nausea, vomiting or chills) through self-assessment via participant diaries and in-person clinical assessments.

Number of participants with any treatment-emergent clinical laboratory abnormalities (chemistry, hematology and liver function tests)
Day 1 through 36 weeks

A treatment-emergent clinical laboratory abnormality is a clinical laboratory value that increases at least 1 toxicity grade from baseline at any postbaseline timepoint up to 30 days after permanent discontinuation of study drug. Clinical laboratory abnormalities are graded using DAIDS Table for Grading and Severity of Adult and Pediatric Events, Corrected Version 2.1, July 2017.

Number of participants with CMV vector viremia (blood)
Day 1 through 36 weeks

Quantitative polymerase chain reaction (qPCR) for CMV will be performed on participant blood samples collected throughout the study. Positive samples will undergo follow-up confirmatory PCR testing to differentiate wild-type CMV from CMV vaccine vector sequences.

Number of participants with CMV vector shedding (urine and saliva)
Day 1 through 36 weeks

Quantitative polymerase chain reaction (qPCR) for CMV will be performed on both saliva and urine samples collected from participants throughout the study to monitor for viral shedding. Positive samples will undergo follow-up confirmatory PCR testing to differentiate wild-type CMV from CMV vaccine vector sequences.

Frequently asked questions about VIR-1111

What is VIR-1111 used for?

VIR-1111 is an investigational vaccine being developed for the prevention of HIV I Infection. It is currently in Phase 1 clinical development and is being studied in healthy volunteers to evaluate its safety and immunogenicity.

Who makes VIR-1111?

VIR-1111 is being developed by Vir Biotechnology, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol VIR. The company is conducting clinical research on this investigational vaccine for HIV I Infection.

What phase is VIR-1111 in?

VIR-1111 is in Phase 1 clinical development. It is an investigational vaccine and has not been approved by regulatory authorities. One Phase 1 clinical trial has been completed, and the vaccine remains under clinical investigation for HIV I Infection.

What clinical trials is VIR-1111 in?

VIR-1111 has been studied in one completed Phase 1 clinical trial, NCT04725877, titled "VIR-1111: A Prototype Human CMV-based Vaccine for Human Immunodeficiency Virus (HIV) in Healthy Volunteers." The trial enrolled 27 participants in the United States and was a randomized, double-blind, placebo-controlled study.

Is VIR-1111 a monoclonal antibody?

VIR-1111 is classified as a monoclonal antibody modality, but it is being developed as a vaccine for HIV I Infection. The completed Phase 1 trial evaluated it as a prototype human cytomegalovirus-based vaccine in healthy volunteers.
