Pooled safety analysis of pimitespib for the treatment of patients with advanced gastrointestinal stromal tumors.
Trial report in International journal of clinical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02965885 (A Phase IA/IB Study Evaluating TAS-116 in Patients With Advanced Solid Tumors), which is not on this 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.

Abstract
backgroundPimitespib is a first-in-class heat shock protein 90 (HSP90) inhibitor, approved in Japan for the treatment of advanced gastrointestinal stromal tumors (GIST). This study aimed to characterize the incidence and time course of adverse drug reactions (ADRs) associated with pimitespib.
methodsThis was a post hoc analysis of pooled safety data from a phase 1 (NCT02965885), phase 2 (jRCT2080223127), and phase 3 (jRCT2080224033) study of pimitespib in patients with advanced GIST. The present analysis included Japanese study participants who received oral pimitespib 160 mg once daily for 5 days followed by 2 days' rest per week in 21-day cycles. Pooled safety outcomes included the incidence and severity of ADRs; ADRs leading to treatment modifications or discontinuation; and the time to ADR onset and resolution.
resultsIn total, 119 patients were included. ADRs were reported in 114 patients (95.8%); gastrointestinal ADRs were most common (99 patients [83.2%]; most often diarrhea [75.6%]) and ocular ADRs occurred in 26 patients (21.8%; most often night blindness [11.8%]). Median time to first onset of any gastrointestinal ADR was 3.0 days; the outcome of gastrointestinal ADRs was recovered/recovering in 61 patients (61.6%), with a median time to resolution of 44.0 days. Median time to first onset of any ocular ADR was 19.0 days; ocular ADRs were recovered/recovering in 20 patients (76.9%), with a median time to resolution of 21.0 days.
conclusionsThis analysis suggests that most ADRs associated with pimitespib are manageable and reversible, thus supporting its use in patients with advanced GIST.
