Safety and efficacy of two dose levels of taliglucerase alfa in pediatric patients with Gaucher disease
Bibliographic record
Abstract
Taliglucerase alfa is a plant cell-expressed beta-glucocerebrosidase approved in the United States, Israel, Australia, Canada, and other countries for enzyme replacement therapy in adults with Type 1 Gaucher disease (GD), for treatment of pediatric patients in the United States, Australia, and Canada, and for the hematologic manifestations of Type 3 GD in pediatric patients in Canada. This multicenter, randomized, double-blind, parallel-dose, 12-month study assessed efficacy and safety of taliglucerase alfa in pediatric patients with GD. Eleven children were randomized to taliglucerase alfa 30U/kg (n=6) or 60U/kg (n=5) per infusion every other week. From baseline to month 12, the following changes were noted in the taliglucerase alfa 30-U/kg and 60-U/kg dose groups, respectively: median hemoglobin concentrations increased by 12.2% and 14.2%; the interquartile ranges of median percent change in hemoglobin levels from baseline were 20.6 and 10.4, respectively; mean spleen volume decreased from 22.2 to 14.0 multiples of normal (MN) and from 29.4 to 12.9 MN; mean liver volume decreased from 1.8 to 1.5 MN and from 2.2 to 1.7 MN; platelet counts increased by 30.9% and 73.7%; and chitotriosidase activity was reduced by 58.5% and 66.1%. Nearly all adverse events were mild/moderate, unrelated to treatment, and transient. One patient presented with treatment-related gastroenteritis reported as a serious adverse event due to the need for hospitalization for rehydration. No patient discontinued. These data suggest that taliglucerase alfa has the potential to be a therapeutic treatment option for children with GD. This study was registered at www.clinicaltrials.gov as NCT01132690.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
