Development and Evaluation of a Bispecific Single-Chain Antibody Targeting PSMA and CD3 to Enhance T-Cell-Mediated Lysis.
Article in American journal of men's health. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Prostate cancer is among the most prevalent malignancies in men worldwide and is associated with poor outcomes in advanced stages. Conventional therapies, including androgen deprivation and chemotherapy, provide limited benefit and are often accompanied by significant toxicity. This study aimed to evaluate the efficacy and immunological impact of a novel bispecific single-chain antibody targeting prostate-specific membrane antigen (PSMA) and CD3 in preclinical models. A bispecific single-chain variable fragment (scFv) antibody was engineered to simultaneously bind PSMA on tumor cells and CD3 on T cells. The construct was expressed in mammalian cell lines, and its purity, specificity, and binding affinity were characterized. In vivo efficacy was assessed in murine xenograft models of prostate cancer, with treatment groups receiving human T cells with or without the bispecific antibody. Tumor growth, survival, and immunological responses were evaluated using flow cytometry, immunohistochemistry, and histopathological analysis. The bispecific antibody demonstrated high purity (mean 97.7%), strong binding affinity to PSMA (Kd 0.23 nM) and CD3 (Kd 0.30 nM), and specificity >99%. In vivo, treatment significantly reduced tumor growth (75.45 ± 3.52 mm³ vs. 543.39 ± 44.35 mm³ in controls at Day 28; Student's
