1 · What the graph read from 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.

Abstract

aimThis Phase Ib/II study aimed to evaluate the safety, tolerability, pharmacokinetics, and efficacy of Firsekibart in the treatment of gout flares.

methodsPhase Ib part utilized an open-label, single-dose, dose-escalation design. Patients were enrolled and received a single subcutaneous injection of Firsekibart at a dose of 50, 100, or 195 mg. Phase II part was a multicenter, randomized, double-blind, parallel, positive-controlled study. Patients were assigned to receive either Firsekibart (100 or 195 mg) or Diprospan.

resultsAs of June 9, 2022, a total of 120 patients (Phase Ib N = 29, Phase II N = 91) received the study drugs. In Phase Ib, Firsekibart demonstrated dose-dependent efficacy. Firsekibart 50 mg treatment provided less pain relief compared to the 100 mg and 195 mg. In Phase II, the visual analogue scale (VAS) score decreased by 5.51 ± 1.56, 4.72 ± 1.56 and 4.94 ± 2.44 cm after 72 h in Firsekibart 195 mg, 100 mg and Diprospan groups, respectively. Firsekibart 195 mg treatment showed a more effective pain relief trend. The pharmacokinetic (PK) profile of serum Firsekibart exhibits typical characteristics of monoclonal antibodies, featuring slow absorption (median T

conclusionA single subcutaneous injection of Firsekibart is safe and well tolerated in the treatment of gout flares. It provides dose-dependent pain relief with favorable pharmacokinetic properties and potential for reducing the risk of gout flare recurrence. TRAIL REGISTRATION: Trial Registration: ClinicalTrials.gov NCT05328531.
