Dose escalation study of the HLA-A2-WT1 CD3 bispecific antibody RO7283420 in relapsed/refractory acute myeloid leukemia.
Trial report in Blood neoplasia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
A novel T-cell bispecific antibody (TCB), RO7283420, engaging CD3 and the HLA-A2-Wilms tumor protein 1 complex, was evaluated in this phase 1 study to characterize safety and tolerability, determine the maximum tolerated dose (MTD), and recommend a phase 2 dose for patients with relapsed/refractory acute myeloid leukemia in 2 groups: hematologic (group I, n = 57) and molecular (group 2, n = 5) relapse. In group I, 51 received RO7283420 intravenously (IV) and 6 subcutaneously. The IV doses ranged from 0.15-4 mg (flat; n = 13), 3-18 mg (step-up; n = 34) every 3 weeks, or 9 mg weekly (step-up; n = 4). The MTD was 1/3/12 mg every 3 weeks. The most frequent adverse event in the overall population was cytokine release syndrome (61.3%) with grade ≥3 recorded in 9.7% of patients. Twelve dose-limiting toxicities were reported in 11 patients and 12 (19.4%) grade 5 adverse events, including 1 hemophagocytic lymphohistiocytosis case related to RO7283420. Among the 42 efficacy-evaluable IV patients in group I, 4.8% achieved complete remission (CR), and 2.4% achieved CR with incomplete hematologic recovery. RO7283420 induced pharmacodynamic changes in peripheral blood (PB) at doses ≥1 mg, including significant T-cell activation and expansion in the PB and bone marrow (BM). Significant associations were found between blast reduction and baseline immunophenotype, including lower regulatory T cells and higher non-exhausted CD8
