XY0206 targets FLT3-dependent resistance states in acute myeloid leukemia.
Article in The Journal of clinical investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04471064 (A Multicenter, Open, Dose Increasing Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Primary Efficacy of xy0206 Tablets in Relapsed / Refractory Acute Myeloid Leukemia Subjects), 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.

Abstract
Activating mutations in FMS-like tyrosine kinase 3 (FLT3) drive aggressive acute myeloid leukemia (AML) and confer poor prognosis. Although FLT3 inhibitors have improved AML outcomes, their efficacy is frequently limited by microenvironment-mediated signaling and treatment-emergent resistance. XY0206 is a structurally optimized derivative of sunitinib, an inhibitor approved for multiple solid tumors. Biochemical, multi-omics, and functional analyses showed that XY0206 directly engages FLT3 and suppresses downstream STAT5, AKT, and ERK signaling, resulting in apoptosis of AML cells with FLT3-internal tandem duplications (FLT3-ITD). Across models of FLT3-dependent resistance, XY0206 retained antileukemic activity, including in FLT3-ITD cells harboring the F691L gatekeeper mutation, a recurrent alteration conferring resistance to approved FLT3 inhibitors. In primary AML blasts and xenograft models, XY0206 exhibited enhanced antileukemic activity with favorable tolerability relative to gilteritinib. In a phase I/II trial of XY0206 monotherapy in patients with relapsed or refractory (R/R) AML (ClinicalTrials.gov identifier NCT04471064), XY0206 achieved a composite complete remission rate (CRc) of 45.7% overall, with a notable 60.0% CRc rate among patients with FLT3-ITD mutations. Three of 8 patients with prior FLT3 inhibitor-exposed R/R AML also achieved CRc. Together, these findings support further clinical evaluation of XY0206 as an FLT3-directed therapeutic in AML, particularly in disease settings with reduced sensitivity to existing FLT3 inhibitors.
