Safety, Tolerability, Pharmacokinetics, and Viral Pharmacodynamics of the Monoclonal Antibody Sotrovimab Administered via Intramuscular Injection in Participants with Early, Mild-to-Moderate COVID-19: A Randomized Clinical Trial.
Trial report in Drugs in R&D, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04779879 (A Multicenter, Randomized, Double-Blind, Parallel Group Phase II Study to Evaluate the Safety, Tolerability and Pharmacokinetics of a Second Generation VIR-7831 Material in Non-Hospitalized Participants With Mild to Moderate Coronavirus Disease 2019), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
BACKGROUND AND
objectivesNew coronavirus disease 2019 (COVID-19) therapeutics, including intramuscular (IM) formulations, may increase patient access. In COMET-TAIL, sotrovimab 500 mg IM was non-inferior to 500 mg intravenous (IV) in reducing the risk of COVID-19 progression; however, 250 mg IM was associated with more hospitalizations, despite similar viral load (VL) reductions to 500 mg IM.
methodsCOMET-PEAK was a randomized, three-part study to assess safety, tolerability, and viral pharmacodynamics of sotrovimab in adults with early, mild-to-moderate COVID-19. Parts B/C evaluated sotrovimab 500-mg IV infusion versus 500-mg or 250-mg IM injection. The primary objective was to compare virologic response of sotrovimab IM versus IV (mean area under the curve from day 1 to day 8 [AUC
resultsParts B/C included 167 and 157 participants, respectively. Median age range was 42-47 years, and approximately 50% of participants had one or more risk factor for severe disease. The primary objective was met: the ratio of geometric mean VL AUC
conclusionsBoth sotrovimab IM doses were equivalent to 500 mg IV with respect to SARS-CoV-2 VL change. IM administration was safe and well tolerated. The validity of VL as a biomarker for COVID-19 progression warrants further study. CLINICAL
