Trial overview
Official title: Prospective cohort study to monitor the emergence of SARS-CoV-2 spike viral variants in immunocompromised non-hospitalized patients exposed to sotrovimab in Great Britain: LUNAR study
Trial description: Sotrovimab binds to a conserved epitope on the severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 spike protein outside the receptor-binding motif and has been shown to reduce the risk of hospitalization and/or death when administered as early treatment in non-hospitalized patients that are at risk for progression to severe disease. Immunocompromised (IC) patients are prioritized to receive early treatment for COVID-19 as they are at high risk of disease progression, and because of their potential for prolonged viral shedding and the resulting increased risk of emergent viral mutations and potential onward community transmission. This genomic surveillance study will aim to describe changes in the SARS-CoV-2 spike protein observed in IC participants receiving sotrovimab as standard of clinical care in sentinel sites at a national level to assess potential emergence of viral variants.
Primary purpose:
Treatment
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Not applicable
Primary outcomes:
Proportion of participants eligible for sequence analysis with amino acids (AA) change from baseline in the epitope of sotrovimab binding
Timeframe: Baseline (Day 0) and up to Day 28 ([plus-minus] ± 2 days)
Proportion of participants eligible for sequence analysis that have any AA, change from baseline in the spike protein
Timeframe: Baseline (Day 0) and up to Day 28 (± 2 days)
Secondary outcomes:
Proportion of participants eligible for sequence analysis with variants of concern (VOC) and variants under investigation (VUI) on the earliest possible sample including baseline
Timeframe: Baseline (Day 0) and up to Day 28 (± 2 days)
Proportion of participants with undetectable virus by reverse transcriptase polymerase chain reaction (RT-PCR)
Timeframe: Baseline (Day 0) and up to Day 28 (± 2 days)
Proportion of participants with all cause hospital admissions and COVID-19 related hospital admissions
Timeframe: Up to Day 28 (± 2 days)
Proportion of participants on new or increased oxygen support, including those requiring mechanical ventilation or extracorporeal membrane oxygenation (ECMO)
Timeframe: Up to Day 28 (± 2 days)
Proportion of participants with all cause intensive care unit (ICU) admission
Timeframe: Up to Day 28 (± 2 days)
Proportion of participants with all cause deaths and COVID-19 related deaths
Timeframe: Up to Day 28 (± 2 days)
Number of participants with AA changes in SARS-CoV-2 spike protein is >5% in samples compared to baseline following sotrovimab administration
Timeframe: Baseline (Day 0) and up to Day 28 (± 2 days)
Number of participants with AA changes in the consensus sequence (>50%) of SARS-CoV-2 spike protein samples from baseline following sotrovimab administration
Timeframe: Baseline (Day 0) and up to Day 28 (± 2 days)
