Trial overview
These clinical trials are studying Sotrovimab as part of research on COVID-19 and SARS-CoV-2 infection.[1][2] The available trial data show two Phase 3 interventional studies that focus on virus control, immune response, and follow-up after treatment with monoclonal antibodies.[1][2]
TURN-COVID Biobank study
The first study is the TURN-COVID Biobank, a Dutch cohort study for the evaluation of neutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2.[1] It is listed as a Phase 3 interventional study with 400 participants and the status Completed.[1]
This study includes people with SARS-CoV-2 infection and examines several treatment options used in the study setting, including Xevudy, which is the product name listed for Sotrovimab in the trial data.[1] Other listed treatments in the same study are Ronapreve, EVUSHELD, and Paxlovid.[1]
The main goals are to study how the viral load changes during and after treatment, whether infection occurs when these treatments are used to prevent disease, and whether viral variants, spike mutations, or immune escape appear during treatment.[1] The study also measures viral antibody and inflammatory response changes over time and aims to create a biobank for future research.[1]
Immune response and revaccination study
The second study is titled Temporal kinetics of antibody and cellular response markers and relative impact of revaccination in patients recovered from COVID-19 after treatment with monoclonal antibodies.[2] It is an authorised Phase 3 interventional study with 150 participants.[2]
This study includes people who recovered from COVID-19 after receiving monoclonal antibodies and looks at the effect of different vaccination histories at the time of infection.[2] The intervention list includes Comirnaty, Spikevax, EVUSHELD, Xevudy, and Nuvaxovid.[2]
The main endpoint is the effect of revaccination at 4 versus 12 months on the timing of humoral and cellular response markers.[2] In simple terms, the study is checking how antibody-based and cell-based immune responses change over time and whether the timing of revaccination matters.[2]
Outcomes and endpoints
The first trial measures SARS-CoV-2 viral load kinetics, infection occurrence when used as prophylaxis, viral variant changes, spike mutations, immune escape, and immune and inflammatory response kinetics.[1] It also has a biobank goal, which means it collects and stores samples for future questions about current and future COVID-19 treatments.[1]
The second trial measures the effectiveness of revaccination timing on the temporal kinetics of humoral and cellular response markers.[2] This means the researchers are tracking how the immune response changes across time after vaccination and after earlier monoclonal antibody treatment.[2]
Who is being studied
The target population in these trials includes people with SARS-CoV-2 infection or COVID-19 infection, as well as people who recovered after receiving monoclonal antibodies.[1][2] Some participants are studied based on their vaccination status at the time of infection or during follow-up.[2]
- People with active infection: These participants help researchers see how the treatment affects virus levels and immune responses during illness.[1]
- People recovered after treatment: These participants help researchers understand longer-term immune markers after monoclonal antibody treatment.[2]
- People with different vaccination timing: These participants help researchers compare revaccination at 4 months and 12 months.[2]
Study design and phase
Both studies are interventional, which means researchers are actively giving treatments or vaccines and then measuring the results.[1][2] Both are also Phase 3 studies, which usually means they are testing the treatment in larger groups and looking closely at real patient outcomes.[1][2]
The trial data do not provide detailed participant rules such as age limits or exclusion criteria, so the most reliable description is that the studies focus on patients with SARS-CoV-2 infection, COVID-19 infection, or recovery after monoclonal antibody treatment.[1][2]
