Novel loop structure of human IgG1 Fc fused CD38 targeted bispecific antibodies and their anti-tumor effect in acute myeloid leukemia.
Article in Journal of translational medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAcute myeloid leukemia (AML) still lacks an ideal immunotherapy target. CD38 serves as a potential therapeutic target for AML. Classical bispecific antibody (BsAb) requires continuous infusion due to small molecular size and short half-life.
methodsThe anti-human CD38 single-chain variable fragment (scFv) and anti-human CD3 scFv were cloned to expression plasmids. ExpiCHO-S cells were transfected, and the anti-CD38/anti-CD3 bispecific antibody (38-3-BsAbs) in CHO supernatants was efficiently purified. The anti-AML efficacy of 38-3-BsAbs was evaluated in vitro and in vivo.
resultsThe novel loop structures of non-human IgG Fc fused and human IgG1 Fc fused anti-CD38/anti-CD3 BsAbs, 38-3-loop-BsAb and 38-3-loopFc-BsAb, were designed and produced. Both 38-3-loop-BsAb and 38-3-loopFc-BsAb showed excellent anti-AML effects at low concentrations in vitro. AML xenograft NOD-scid IL2gamma
conclusionsWe report on new structures of 38-3 bispecific antibody and demonstrate their anti-tumor effect in the treatment of AML.
