Abstract
BACKGROUND/AIMS: This Phase III study examined the efficacy and safety of C.E.R.A., a continuous erythropoietin receptor activator, given once every 2 weeks (Q2W) via subcutaneous or intravenous injection using pre-filled syringes, for maintaining hemoglobin (Hb) levels in patients with chronic kidney disease (CKD) on dialysis who converted directly from epoetin therapy. METHODS: Patients (n = 336) were randomized 1:1 to continue epoetin at their current dose, route and administration interval (once to three times weekly (QW-TIW)), or receive C.E.R.A. Q2W by the same route as previous epoetin treatment for 36 weeks. Dosage was adjusted to maintain patients' Hb within +/-1.0 g/dl of baseline value and within 10.0-13.5 g/dl. Primary endpoint was mean change in Hb between baseline and the evaluation period (weeks 29-36). RESULTS: Mean change in Hb for C.E.R.A. and epoetin was 0.088 and -0.030 g/dl, respectively (endpoint Hb 11.93 and 11.86 g/dl, respectively). Analysis showed that C.E.R.A. was as effective as epoetin in maintaining Hb (p < 0.0001), and was well tolerated. The administration route had no impact on primary endpoint. CONCLUSION: Q2W C.E.R.A. administered using pre-filled syringes effectively maintains stable control of Hb in patients on dialysis who convert directly from epoetin QW-TIW.

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
