Real-World Data on Inotuzumab Ozogamicin for Adult Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia: A GRELAL-Chile Study.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
backgroundInotuzumab Ozogamicin (InO) has shown efficacy in relapsed/refractory acute lymphoblastic leukemia (R/R ALL), but evidence from Latin America is scarce. We evaluated the outcomes of Chilean patients treated with InO in public and private health centers.
methodsWe retrospectively analyzed 35 patients with R/R ALL (median age 33 years; 54% male). Twenty percent had BCR::ABL-positive ALL, 78% expressed CD22, and 91% expressed CD19. Response rates, measurable residual disease (MRD), survival outcomes, and treatment-related toxicities were assessed. Multivariate analyses explored prognostic factors.
resultsComplete remission or remission with incomplete recovery (CR/CRi) was achieved in 74% of patients. Among those evaluated, 82% reached MRD < 0.01%. Patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT) after InO had superior overall survival (OS) compared with those who did not (24.2 vs. 5.2 months). Median progression-free survival (PFS) was 6.9 months and median OS was 8.8 months. Sinusoidal obstruction syndrome occurred in 14% of patients but was generally mild. Multivariate analysis identified comorbidities and high blast counts as adverse prognostic factors, whereas MRD negativity and subsequent Allo-HSCT were associated with improved outcomes.
conclusionsInO demonstrated high remission and MRD negativity rates in Chilean patients with R/R ALL, with OS and PFS comparable to existing research. Although SOS incidence was higher, it was generally mild. Achieving MRD negativity and proceeding to Allo-HSCT provided the greatest survival benefit. Study limitations include short follow-up and limited data.
