Safety, tolerability, pharmacokinetics, and pharmacodynamics of a novel kappa opioid receptor agonist ZYKR1: a randomized double-blind placebo-control phase 1 study in healthy adult human participants.

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
To perform first-in-human single-dose escalation trial of ZYKR1, which is a potent, selective, and peripherally-restricted kappa opioid receptor agonist, is the purpose of this study. This randomized, double-blind, placebo-controlled single ascending dose study conducted at Zydus Research Centre, Ahmedabad, India included healthy male participants aged 18-55 years and weighing > 50 kg. The primary objective was to evaluate the safety and tolerability of ZYKR1. The secondary objective was to evaluate the pharmacokinetics and pharmacodynamics (PD) of ZYKR1. Participants received ZYKR1 (0.5 - 6 mcg/kg) or placebo infused intravenously in 15 ± 1 min. Of total five dose groups (0.5 - 6 mcg/kg), each group included eight participants with six and two randomized to ZYKR1 and placebo, respectively. Three participants experienced six treatment-emergent adverse events (TEAEs); two were gastrointestinal disorders (nausea and vomiting at 2 mcg/kg); and four were related to the nervous system (headache (at 2 mcg/kg) and facial tingling, facial numbness and paresthesia (at 6 mcg/kg)); all TEAEs were mild and resolved without sequelae.
