Long-term efficacy and safety of pexidartinib in patients with tenosynovial giant cell tumor: final results of the ENLIVEN study.
Trial report in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02371369 (A Double-blind, Randomized, Placebo-controlled Phase 3 Study of Orally Administered PLX3397 in Subjects With Pigmented Villonodular Synovitis or Giant Cell Tumor of the Tendon Sheath), which is not on this map.

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.

Abstract
backgroundPexidartinib is approved in the US, Taiwan, and Korea for adults with symptomatic tenosynovial giant cell tumor (TGCT) associated with severe morbidity or functional limitations and not amenable to improvement with surgery based on the phase III ENLIVEN study (NCT02371369). We report the final long-term efficacy and safety results from ENLIVEN.
methodsAdults with symptomatic TGCT not eligible for surgery were enrolled and randomized to pexidartinib or placebo (part 1). The blinded phase (part 1) ended at week 25; patients received pexidartinib (800 mg/day) until progression, toxicity, or study completion (part 2). This analysis includes patients who received pexidartinib at any time during ENLIVEN. Centrally reviewed overall response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and tumor volume score (TVS), time to response, duration of response (DOR), patient-reported outcomes (PROs), and long-term safety were assessed.
resultsOverall, 91 patients received pexidartinib. With a median follow-up of 31.2 (range: 2-66) months, ORR was 60.4% and 68.1% by RECIST and TVS, respectively. Median DOR by RECIST was not reached (range: 0.03-63.4 months). Most responses were within the first 6 months of treatment; most responders were on 800 mg vs 600/400 mg dose levels, respectively. Throughout parts 1 and 2, 3 (3%) patients had progressive disease per RECIST without dose reduction/interruption. PROs improved or were maintained. The most common grade 3/4 treatment-emergent adverse events were aspartate aminotransferase (AST) increase (9%), alanine aminotransferase (ALT) increase (10%), and hypertension (8%). Twenty-eight (31%) patients had AST or ALT ≥3 times the upper limit of normal (ULN); 17 (19%) patients had AST or ALT ≥5 times the ULN. No new safety signals were observed after long-term pexidartinib treatment.
conclusionsFinal long-term ENLIVEN results demonstrated that pexidartinib sustained clinical benefit, with increased ORR by RECIST and TVS compared to the end of the blinded phase at week 25. No new safety signals were reported.
