Discovery and Phase 1 study of a novel monoclonal antibody against human IL-1β for the treatment of IL-1β-mediated diseases.

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
Interleukin-1β (IL-1β) is a key mediator of innate immunity against pathogen infections. However, dysregulated IL-1β activity is associated with various autoinflammatory, autoimmune, degenerative, atherosclerotic diseases, and cancers. Biologic drugs that neutralize excess IL-1β activity, such as canakinumab, have been effective in treating IL-1β-mediated diseases. This article reports the discovery and development of a novel humanized anti-IL-1β antibody, designated as TAVO103A, which exhibited potent binding affinities to human and monkey IL-1β. TAVO103A demonstrated more potent neutralization of IL-1β activities compared to canakinumab in multiple assays, including tests on the IL-1β-driven signal transduction cascade, inflammatory cytokine release from MRC-5 cells, chemokine release from A549 cells, and the proliferation of D10.G4.1 helper T cells. Ex vivo studies showed that TAVO103A effectively neutralized IL-1β-mediated release of pro-inflammatory cytokines from peripheral blood mononuclear cells. In addition, TAVO103A exhibited dose-dependent efficacy in a knee joint inflammation mouse model. TAVO103A underwent Fc engineering to reduce binding to Fcγ receptors, increase affinity to FcRn receptors, and enhance its resistance to proteolytic degradation. In a Phase 1 study, TAVO103A was found to be safe, well tolerated, and demonstrated a median half-life of 63 days in healthy subjects. By recognizing a different epitope, TAVO103A provided more potent neutralization of IL-1β activities, a longer circulating half-life, and improved safety profiles compared to canakinumab, positioning it to be a potential best-in-class therapeutic option for various IL-1β-mediated diseases.
