COVID19 Paid Clinical Trials in Virginia

A randomized, observer-blind, placebo-controlled immuno-bridging, and broadening study to demonstrate the equivalence of the immune response between participants enrolled in Phase 3 efficacy trial in India and demographically diverse healthy adult participants in the US which matched in age and vaccine formulation setting to whom those efficacy results are extrapolated; and to assess the broadening of the BBV152 in participants who previously received two shots of messenger ribonucleic acid (mRNA) COVID-19 vaccine at least 6 months earlier or one-shots of viral vector J&J/Janssen COVID-19 vaccine at least 2 months earlier. Safety and tolerability evaluation is a secondary endpoint. Read Less

The overall purpose of this observational cohort study is to characterize COVID-specific immune responses to SARS-CoV-2 exposure or COVID vaccination in a real-world setting. Participants will be asked to provide blood samples (either a normal venous blood draw, a few drops of blood obtained with a small finger-stick device, or both), as well as saliva or nasal swab sample at a series of visits. Subjects will receive results of the testing that is approved for routine clinical use (i.e., their AditxtScore), while residual samples from each visit will be stored for future testing. These efforts will support ongoing AditxtScore test development and enhance the effectiveness of its interpretation - aiding efforts to maximize benefits of clinical laboratory testing in the pandemic response.

The primary objective of the study is to characterize the concentrations of casirivimab+imdevimab in serum over time after a single subcutaneous (SC) administration The secondary objectives of the study are: To assess the safety and tolerability of SC or single administration of casirivimab+imdevimab To assess the occurrence of grade ≥3 injection site reactions and grade ≥3 hypersensitivity reactions, in participants treated with SC doses of casirivimab+imdevimab To assess the immunogenicity of casirivimab+imdevimab Read Less
