Abstract 12470: Sacubitril/Valsartan in Patients With Heart Failure and Deterioration of Kidney Function to Estimated Glomerular Filtration Rate Less Than 30ml/min/1.73m <sup>2</sup> : Insights From PARAGON-HF and PARADIGM-HF
Bibliographic record
Abstract
Background: Sacubitril/valsartan is a foundational therapy for patients with heart failure (HF). Although current US FDA labeling does not identify threshold kidney function below which initiation or continuation of sacubitril/valsartan is precluded, guidelines generally identify eGFR<30mL/min/1.73m 2 as a contraindication to therapy. Methods: The RCTs PARAGON-HF and PARADIGM-HF assessed sacubitril/valsartan versus valsartan or enalapril in patients with HF. Patients with eGFR <30 (PARADIGM) or <25 mL/min/1.73 m 2 (PARAGON) at randomization were excluded. Discontinuation below this eGFR during follow-up was not mandated. We examined the effects of sacubitril/valsartan on efficacy and safety in patients experiencing progression of CKD to eGFR<30mL/min/1.73m 2 in follow-up. Results: Among 4,746 patients in PARAGON-HF and 8,346 patients in PARADIGM-HF (with eGFR>30ml/min/1.73m 2 at randomization), 613 (12.9%) and 691 (8.3%), respectively, had an eGFR<30mL/min/1.73m 2 at least once in follow-up. Patients with CKD progression had higher rates of study drug discontinuation and hyperkalemia (>5.5 mmol/L); however, rates remained similar between treatment groups. Patients with deterioration in kidney function to eGFR<30ml/min/1.73m 2 were at a higher risk of the primary composite outcome in both PARAGON-HF (RR 2.08; 95% CI: 1.72-2.52) and PARADIGM-HF (HR 2.32; 95% CI: 1.94-2.76). The incidence of the primary composite outcome was lower in patients treated with sacubitril/valsartan irrespective of deterioration in kidney function to eGFR<30mL/min/1.73m 2 in both PARAGON-HF (P int =0.74) and PARADIGM-HF (P int =0.50); Figure 1 . Conclusion: HF patients with progression of CKD to eGFR<30ml/min/1.73m 2 experience high risk of CV outcomes and continuation of sacubitril/valsartan was associated with persistent benefit. These data support potential continuation of sacubitril/valsartan, even among patients experiencing progression to advanced CKD.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
