To describe characteristics and acute clinical outcomes for patients with COVID-19 treated with sotrovimab, nirmatrelvir/ritonavir or molnupiravir, or untreated patients at highest risk per National Health Service (NHS) criteria. Retrospective study of non-hospitalized patients between 1 December 2021 and 31 May 2022, using data from the Discover-NOW dataset (North-West London). Included patients were aged ≥12 years and treated with sotrovimab, nirmatrelvir/ritonavir or molnupiravir, or untreated but expected to be eligible for early treatment per NHS highest-risk criteria. COVID-19-related and all-cause hospitalizations were reported for 28 days from COVID-19 diagnosis (index). Subgroup analyses were conducted in patients with advanced renal disease, those aged 18–64 and ≥65 years, and by period of Omicron BA.1, BA.2 and BA.5 (post-hoc exploratory) predominance. Overall, 1503 treated and 4044 eligible high-risk untreated patients were included. A high proportion of patients on sotrovimab had advanced renal disease (29.3%), ≥3 high-risk comorbidities (47.6%) and were aged ≥65 years (36.9%). Five of 696 (0.7%) patients on sotrovimab, <5/337 (0.3–1.2%) on nirmatrelvir/ritonavir, 10/470 (2.1%) on molnupiravir and 114/4044 (2.8%) untreated patients were hospitalized with COVID-19. Similar results were observed across all subgroups. The proportion of patients dying within 28 days of the index period was similarly low across all cohorts (<2%). Patients receiving sotrovimab appeared to show evidence of multiple high-risk comorbidities. Low hospitalization rates were observed for all treated cohorts across subgroups and periods of predominant variants of concern. These results require confirmation with comparative effectiveness analyses adjusting for differences in underlying patient characteristics. [ABSTRACT FROM AUTHOR]

Background: To describe outcomes of high-risk patients with coronavirus disease 2019 (COVID-19) treated with sotrovimab, other monoclonal antibodies (mAbs), or antivirals, and patients who did not receive early COVID-19 treatment. We also evaluate the comparative effectiveness of sotrovimab versus no treatment in preventing severe clinical outcomes. Methods: This observational retrospective cohort study analyzed Mayo Clinic electronic health records. Non-hospitalized adult patients diagnosed with COVID-19 from May 26, 2021 and April 23, 2022 and at high risk of COVID-19 progression were eligible. The primary outcome was 29-day all-cause hospitalization and/or death. Outcomes were described for patients treated with sotrovimab, other mAbs, or antivirals, and eligible but untreated patients, and compared between sotrovimab-treated and propensity score (PS)-matched untreated cohorts. Results: We included 35,485 patients (sotrovimab, 1369; other mAbs, 6488; antivirals, 133; high-risk untreated, 27,495). A low proportion of patients treated with sotrovimab (n = 33/1369, 2.4%), other mAbs (n = 147/6488, 2.3%), or antivirals (n = 2/133, 1.5%) experienced all-cause hospitalization or death. Among high-risk untreated patients, the percentage of all-cause hospitalization or death was 3.3% (n = 910/27,495). In the PS-matched analysis, 2.5% (n = 21/854) of sotrovimab-treated patients experienced all-cause hospitalization and/or death versus 2.8% (n = 48/1708) of untreated patients (difference, –0.4%; p = 0.66). Significantly fewer sotrovimab-treated patients required intensive care unit admission (0.5% vs 1.8%; difference, –1.3%; p = 0.002) or respiratory support (3.5% vs 8.7%; difference, –5.2%; p < 0.001). Conclusions: There was no significant difference in the proportion of sotrovimab-treated and PS-matched untreated patients experiencing 29-day all-cause hospitalization or mortality, although significantly fewer sotrovimab-treated patients required intensive care unit admission or respiratory support.

Purpose: Emerging SARS-CoV-2 variants have impacted the in vitro activity of sotrovimab, with variable fold changes in neutralization potency for the Omicron BA.2 sublineage and onward. The correlation between reduced in vitro activity and clinical efficacy outcomes is unknown. A systematic literature review (SLR) evaluated the effectiveness of sotrovimab on severe clinical outcomes during Omicron BA.2 predominance. Methods: Electronic databases were searched for peer-reviewed journals, preprint articles, and conference abstracts published from January 1–November 3, 2022. Results: Five studies were included, which displayed heterogeneity in study design and population. Two UK studies had large samples of patients during BA.2 predominance: one demonstrated clinical effectiveness vs molnupiravir during BA.1 (adjusted hazard ratio [aHR] 0.54, 95% CI 0.33–0.88; p = 0.014) and BA.2 (aHR 0.44, 95% CI 0.27–0.71; p = 0.001); the other reported no difference in the clinical outcomes of sotrovimab-treated patients when directly comparing sequencing-confirmed BA.1 and BA.2 cases (HR 1.17, 95% CI 0.74–1.86). One US study showed a lower risk of 30-day all-cause hospitalization/mortality for sotrovimab compared with no treatment during the BA.2 surge in March (adjusted relative risk [aRR] 0.41, 95% CI 0.27–0.62) and April 2022 (aRR 0.54, 95% CI 0.08–3.54). Two studies from Italy and Qatar reported low progression rates but were either single-arm descriptive or not sufficiently powered to draw conclusions on the effectiveness of sotrovimab. Conclusion: This SLR showed that the effectiveness of sotrovimab was maintained against Omicron BA.2 in both ecological and sequencing-confirmed studies, by demonstrating low/comparable clinical outcomes between BA.1 and BA.2 periods or comparing against an active/untreated comparator.

Primary care is a major component of England's National Health Service (NHS), responsible for approximately 300 million consultations per year with GPs in England, which represents 70-90% of all patient contacts with the NHS. In addition to providing healthcare to the registered population, GPs are charged with coordination and gatekeeping of access to services provided by secondary care, tertiary care and other allied healthcare providers. As GPs will be assuming a key role in commissioning health services in England, there is a clear opportunity to re-model care delivery to maximize outcomes, cost efficiency and patient access by focusing on diseases that are most amenable to management in primary care. It is essential that there is evidence to inform what conditions are most sensitive to management in primary care - commonly referred to as primary care sensitive conditions or ambulatory care sensitive conditions. Such definitions would aid resource planning, drafting of local management protocols and simplification of the interface between primary and secondary care for a number of chronic conditions. Indeed, inappropriate utilization of secondary care resources is likely to represent a significant opportunity cost to healthcare providers and may be less desirable for patients.
