Pharmacokinetics, Safety, and Tolerability of Intravenous Felbinac Trometamol in Healthy Chinese Volunteers: A First-in-Human Single- and Multiple-Dose Escalation Phase I Study with a Randomized, Double-Blind, Placebo-Controlled Design.
Trial report in CNS drugs, 2020. 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
backgroundFelbinac trometamol, an anti-inflammatory and analgesic drug, has been used to treat immediate postoperative pain.
objectiveThe aim of this study was to evaluate the safety, tolerability, and pharmacokinetics of single or multiple intravenous infusions of felbinac trometamol in healthy Chinese volunteers.
methodsA total of 56 healthy subjects were enrolled in a single-ascending dose study (11.78-377.00 mg), meanwhile 36 subjects were enrolled in a multiple-ascending dose study (47.13-188.50 mg). Safety endpoints included treatment-emergent adverse events, vital signs, electrocardiograms, and laboratory parameters. Pharmacokinetic endpoints included exposure of subjects to felblinac and metabolites of the drug in plasma, urine, and feces.
resultsFelblinac time to maximum plasma concentration was obtained at 0.5 h, corresponding to the end of the infusion. Maximum plasma concentration and area under the curve increased in a dose-dependent manner for felblinac and its metabolite, showing linear pharmacokinetic characteristics at single and multiple doses. After intravenous infusions of multiple doses three times (30 min each time) per day, the accumulation ratio of felblinac and its metabolite based on the area under the curve had a range of 1.34-1.45 and 1.60-1.87, respectively, across cohorts. After administration of the fourth dose, the plasma concentration of both felblinac and its metabolites was maintained at a steady state. Felbinac trometamol was well tolerated. Neither treatment-emergent adverse event frequency nor severity increased with increasing felbinac trometamol dose.
conclusionsFelbinac trometamol was well tolerated in our study. Based on the dose range in this study, 94.25 mg is the recommended target dose for a phase II study. CLINICAL
