Pharmacokinetics of the Urokinase Receptor-Derived Peptide UPARANT After Single and Multiple Doses Administration in Rats.
Article in European journal of drug metabolism and pharmacokinetics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
BACKGROUND AND
objectivesUPARANT has emerged as a novel therapeutic agent with the potential to treat ocular diseases as assessed by studies in animal models. Since limited information is available on the pharmacokinetics of UPARANT, the aim of this study is to evaluate its pharmacokinetics after single and multiple ascending dose (SAD and MAD) administration in rats.
methodsMale (n = 27) and female (n = 27) Sprague-Dawley rats were divided into six groups (n = 9/sex/group). UPARANT was administered via subcutaneous injection as single (10, 50 or 100 mg/kg; day 1) and multiple (10, 50 or 100 mg/kg/day; 7 consecutive days; day 7) dosing. Blood samples were collected on day 1 (pre-dose, 0.5, 1, 2, 4, 8 and 24 h post dose) and day 7 (pre-dose, 0.5, 1, 2, 4, 8, 24, 48 and 192 h post dose). The plasma concentration of UPARANT was determined by a validated liquid chromatography mass spectrometry method.
resultsThe plasma concentration-time profiles of UPARANT were similar in SAD and MAD administration in both male and female rats. The compound reached maximum plasma concentration (C
conclusionThe pharmacokinetics of UPARANT were not sex-related, and there was negligible accumulation in plasma after 7 days of treatment. However, the compound exhibited no dose-proportional pharmacokinetics after single and multiple ascending subcutaneous dosing.
