Personalized pharmacokinetic-pharmacodynamic guided therapy via an induced pluripotent stem cell-derived multi-organoid platform in NF1-mutant breast cancer.
Article in Signal transduction and targeted therapy, 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
Effective precision oncology demands integration of pharmacokinetics/pharmacodynamics (PK/PD) profiling with tumor-specific genomic features. Here, we present a personalized treatment model using a patient-derived Networking Organoid Culture System (NOCS) composed of intestinal, liver, and kidney organoids differentiated from induced pluripotent stem cells (iPSCs) of an NF1-mutant breast cancer patient. This multi-organoid system enabled individualized assessment of drug absorption, distribution, metabolism, and excretion. Integrative genomic and pathway analyses uncovered therapeutic vulnerabilities, including responsiveness to a novel exon skipping therapy targeting NF1. PK/PD-guided screening on the NOCS prioritized Paxalisib, which, when combined with the exon skipping approach, demonstrated synergistic anticancer efficacy in patient-derived tumor models. These findings establish a clinically relevant framework that integrates multi-organ PK/PD modeling with genotype-driven therapeutic strategies, highlighting the potential of combining targeted gene correction with small-molecule therapy for personalized treatment. This platform offers broad applicability in precision oncology and drug development across diverse genetic contexts.
