Pharmacokinetics and Safety Profile of SNS812, a First in Human Fully Modified siRNA Targeting Wide-Spectrum SARS-CoV-2, in Healthy Subjects.
Trial report in Clinical and translational science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Severe acute respiratory syndrome caused by the coronavirus (SARS-CoV-2) in the COVID-19 pandemic has highlighted the need for effective treatments, as rapid viral mutations complicate therapeutic development. SNS812, a fully modified inhaled siRNA that targets the conserved RNA-dependent RNA polymerase (RdRP) gene of SARS-CoV-2, has been shown to possess its suppression ability against wide-spectrum SARS-COV-2 variants preclinically. To evaluate the safety and tolerability of inhaled SNS812 in healthy participants, a randomized, double-blind, placebo-controlled phase 1 trial was conducted. To justify the first-in-human inhalation study, this research was divided into two parts: single ascending doses (0.3, 0.6, and 1.2 mg/kg) and multiple doses (0.6 and 1.2 mg/kg) of daily inhalation for seven consecutive days to assess the safety, tolerability, immunogenicity, and pharmacokinetics of SNS812. Of the 44 participants, 3 in the 0.3 mg/kg single-dose group, 2 in the 1.2 mg/kg multiple ascending doses group, and 1 in the placebo group reported treatment-emergent adverse events (TEAEs). No serious adverse events (SAEs), treatment-related adverse events (TRAEs), or TEAEs caused discontinuation or deaths were observed. PK showed rapid absorption of SNS812, with peak concentrations (median T
