Population Pharmacokinetics for Pediatric Extrapolation of GenSci006: A 3.75-mg Triptorelin Acetate Microsphere Formulation for Central Precocious Puberty.
Article in Clinical pharmacokinetics, 2026. 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
objectivesTriptorelin acetate microspheres are long-acting gonadotropin-releasing hormone (GnRH) agonist used for treating central precocious puberty (CPP). GenSci006 is a newly developed 3.75-mg formulation intended as a local alternative to Diphereline
methodsThis study comprised two components: (1) PopPK modeling and model-based simulation to characterize exposure and support pediatric extrapolation; and (2) a comparative pharmacodynamic assessment based on serum luteinizing hormone (LH) responses.
resultsThe final PopPK model employed a three-compartment structure with mixed sequential absorption phases (two first-order and a zero-order absorption), capturing triptorelin's multiphasic release. Covariates, including weight, age, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), serum creatinine, total bilirubin, and creatinine clearance, showed no significant effect on PK. Allometric scaling (exponents 0.75 for clearance [CL] and 1 for central volume distribution [V
conclusionModel-based simulations predicted approximately two-fold higher exposure in lighter children (20-30 kg) compared with adults. This difference was not clinically meaningful given the plateau PD effect and wide therapeutic range of triptorelin.
