Nedosiran in pediatric patients with PH1 and relatively preserved kidney function, a phase 2 study (PHYOX8)
Bibliographic record
Abstract
BACKGROUND: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive disorder with dysregulated glyoxylate metabolism in the liver. Oxalate over-production leads to renal stones, progressive kidney damage and renal failure, with potentially life-threatening systemic oxalosis. Nedosiran is a synthetic RNA interference therapy, designed to reduce hepatic lactate dehydrogenase (LDH) to decrease oxalate burden in PH. METHODS: received nedosiran once monthly for 6 months. RESULTS: Urinary oxalate:creatinine (Uox:Ucr) levels reduced by 64% on average. Mean Uox:Ucr reduction was 52% at day 60 and ˃60% at day 180. At one or more study visits, 93.3% (N = 14) of participants reached Uox:Ucr < 1.5 × upper limit of normal (ULN), and 53.3% (N = 8) reached ≤ 1.0 × ULN. Median percent change in plasma oxalate (12.0 µmol/L at baseline) to day 180 was -39.23% (n = 10). Average number of kidney stones per participant remained stable, whilst a 10.1% average decrease in summed surface area was observed. Median percent change from baseline in eGFR was 2.5%, indicating preservation of renal function. CONCLUSIONS: Nedosiran was well tolerated, with only 3 participants experiencing at least one serious adverse event, none considered treatment-related. The incidence of injection site reactions was 6.7% (1/15 participants). In conclusion, nedosiran treatment led to a significant and sustained reduction of Uox levels in children with PH1. These findings support nedosiran treatment in pediatric patients to reduce Uox and shows promise for limiting PH1-related complications.

How this classification was reachedexpand
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.
