Tourmaline Bio, Inc. (NASDAQ: TRML), a late-stage clinical biotechnology company, has presented new data from its ongoing Phase 2 TRANQUILITY trial of pacibekitug at the European Society of Cardiology (ESC) Congress 2025 in Madrid, Spain. The presentation highlighted the drug's ability to consistently reduce high-sensitivity C-reactive protein (hs-CRP) across a broad range of subgroups. Additionally, the study reported statistically significant reductions in secondary pharmacodynamic biomarkers associated with IL-6 pathway activity, including lipoprotein(a), fibrinogen, and serum amyloid A. The trial is a randomized, placebo-controlled study evaluating pacibekitug, a long-acting anti-IL-6 monoclonal antibody, in patients with elevated hs-CRP and chronic kidney disease. The results were previously summarized in a May 2025 press release by Tourmaline.
