Safety, tolerability, and pharmacokinetics of HRS9432(A) injection in healthy Chinese subjects: a phase-I randomized, double-blind, dose escalation, placebo-controlled study.

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
HRS9432(A) is a long-acting echinocandin antifungal medication primarily used to treat invasive fungal infections, particularly invasive candidiasis. The safety, tolerability, and pharmacokinetic characteristics of HRS9432(A) injection were investigated in a randomized, double-blind, placebo-controlled, single- and multiple-ascending-dose Phase I study involving 56 healthy adult subjects. Doses ranging from 200 to 1200 mg were administered. Safety was continually monitored, including adverse events, clinical laboratory examinations, vital signs, 12-lead electrocardiograms, and physical examinations, while the pharmacokinetic profile within the body was evaluated. The results indicated that concentrations of HRS9432 peaked immediately after infusion, demonstrating essentially linear pharmacokinetic characteristics within the dosage range of 200-1,200 mg. It exhibited a low clearance rate and an extended half-life, with a clearance of approximately 0.2 L/h, a volume of distribution of around 40 L, and a half-life of approximately 140h following a single dose. The accumulation index for AUC0-τ after multiple doses ranged from 1.41 to 1.75. No severe adverse events occurred during the study, and the severity of all adverse events was mild or moderate. Therefore, the intravenous administration of HRS9432(A) in healthy Chinese adult subjects, either as multiple infusions of 200 to 600 mg (once a week, four doses) or as a single infusion of 900-1,200 mg, demonstrated overall good safety and tolerability. The pharmacokinetic exhibited essentially linear characteristics in the body, supporting a weekly dosing frequency for clinical applications and providing additional options for the treatment or prevention of invasive fungal infections.
