Abstract
OBJECTIVES: The study aimed to evaluate inclacumab for the reduction of myocardial damage during a percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation myocardial infarction. BACKGROUND: P-selectin is an adhesion molecule involved in interactions between endothelial cells, platelets, and leukocytes. Inclacumab is a recombinant monoclonal antibody against P-selectin, with potential anti-inflammatory, antithrombotic, and antiatherogenic properties. METHODS: Patients (N = 544) with non-ST-segment elevation myocardial infarction scheduled for coronary angiography and possible ad hoc PCI were randomized to receive 1 pre-procedural infusion of inclacumab 5 or 20 mg/kg or placebo. The primary endpoint, evaluated in patients who underwent PCI, received study medication, and had available efficacy data (n = 322), was the change in troponin I from baseline at 16 and 24 h after PCI. RESULTS: There was no effect of inclacumab 5 mg/kg. Placebo-adjusted geometric mean percent changes in troponin I with inclacumab 20 mg/kg were -24.4% at 24 h (p = 0.05) and -22.4% at 16 h (p = 0.07). Peak troponin I was reduced by 23.8% (p = 0.05) and area under the curve over 24 h by 33.9% (p = 0.08). Creatine kinase-myocardial band yielded similar results, with changes of -17.4% at 24 h (p = 0.06) and -16.3% at 16 h (p = 0.09). The incidence of creatine kinase-myocardial band increases >3 times the upper limit of normal within 24 h was 18.3% and 8.9% in the placebo and inclacumab 20-mg/kg groups, respectively (p = 0.05). Placebo-adjusted changes in soluble P-selectin level were -9.5% (p = 0.25) and -22.0% (p < 0.01) with inclacumab 5 and 20 mg/kg. There was no significant difference in adverse events between groups. CONCLUSIONS: Inclacumab appears to reduce myocardial damage after PCI in patients with non-ST-segment elevation myocardial infarction.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
