Matching-adjusted indirect comparison between asciminib and flumatinib as first-line treatment for chronic myeloid leukemia in China.
Article in Translational cancer research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are 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
Background: Asciminib, a novel BCR::ABL1 inhibitor that functions by specifically targeting the myristoyl pocket, has shown superior efficacy and favorable safety and tolerability compared with adenosine triphosphate-competitive tyrosine kinase inhibitors (TKIs) in patients with newly diagnosed chronic myeloid leukemia in chronic phase (CML-CP). Flumatinib, a second-generation TKI available exclusively in China, does not have a head‑to‑head comparison with asciminib till date with asciminib. Therefore, this study aimed to conduct an anchored matching‑adjusted indirect comparison using data from the ASC4FIRST and FESTnd trials to fill this evidence gap. Methods: Imatinib was the common comparator across the ASC4FIRST (NCT04971226) and FESTnd (NCT02204644) trials. To match the two populations, effect modifiers and baseline variables were identified. Adjusted estimates were derived from individual patient-level data (ASC4FIRST) for asciminib and imatinib and from aggregate data for flumatinib (FESTnd). Outcomes were compared based on early molecular response (EMR), major molecular response (MMR), and treatment discontinuation due to adverse events (AEs). Results: Asciminib demonstrated significantly higher EMR rates at 12 weeks (adjusted: 90.0%) than did flumatinib (82.1%), yielding a significantly higher odds ratio [odds ratio (OR): 1.95; 95% confidence interval (CI): 1.05-3.73; P=0.03]. MMR rates, both at 48 and 96 weeks, were significantly higher for asciminib (adjusted: 66.5% and 74.0%, respectively) than for flumatinib (an estimated 52.6% and 61.3%, respectively), with an OR of 1.79 (95% CI: 1.17-2.75; P=0.006). Safety analysis showed fewer discontinuations due to AEs at 48 weeks with asciminib (5.5%) than with flumatinib (10.2%), corresponding to a significantly lower risk of discontinuation due AEs (risk ratio: 0.29; 95% CI: 0.10-0.84; P=0.02). Conclusions: A robust statistical model indicated that asciminib provides consistently superior efficacy and safety over flumatinib, supporting its value as a first-line treatment option for patients with CML-CP.
