Abstract
The ubiquitin-proteasome pathway regulates bone formation through osteoblast differentiation. We analyzed variation alkaline phosphatase (ALP) during carfilzomib treatment. Data from 38 patients enrolled in the PX-171-003 and 29 patients in PX-171-004 studies, for patients with relapsed/refractory myeloma, were analyzed. All patients received 20 mg/m(2) of carfilzomib on Days 1, 2, 8, 9, 15, and 16 of a 28-day cycle. Sixty-seven patients from ALP data were evaluable. In PX-171-003, the ORR (>PR) was 18% and the clinical benefit response (CBR; >MR) was 26%, while in PX-171-004, the ORR was 35.5% overall and 57% in bortezomib-naive patients. ALP increment from baseline was statistically different in patients who achieved ≥ VGPR compared with all others on Days 1 (P = 0.0049) and 8 (P = 0.006) of Cycle 2. In patients achieving a VGPR or better, ALP increased more than 15 units per liter at Cycle 2 Day 1 over baseline. An ALP increase over the same period of time was seen in 26%, 13% and 11% of patients achieving PR, MR, and SD, respectively. This retrospective analysis of patients with relapsed or refractory myeloma treated with single-agent carfilzomib indicates that early elevation in ALP is associated with subsequent myeloma response.

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
