Abstract
e24031 Background: Plinabulin is a novel non-G-CSF small molecule being developed for the prevention of chemotherapy in conjunction with pegfilgrastim and is administered via 30 min IV infusion, 30 min after chemo on Day (D) 1. The QoL was analyzed using the Functional Assessment of Cancer Therapy - General questionnaire (FACT-G) as part of a phase 3 (Ph3) clinical trial comparing pegfilgrastim alone versus pegfilgrastim and plinabulin for the prevention of neutropenia in newly diagnosed breast cancer patients being treated with Docetaxel (75 mg/m 2 ), Doxorubicin (50 mg/m 2 ), and Cyclophosphamide (500 mg/m 2 ) (TAC) on D1 for four 21 D cycles and study treatment. Methods: The FACT-G was administered to patients in China and Ukraine using an ePRO app downloaded onto patients' phones as part of the Phase 3 PROTECTIVE-2 trial (NCT0329457) with TAC. Patients completed the FACT-G during each chemo cycle at D-1, D1, D8 and D15. Patients received reminders 1 hour before the required completion time and all entries were time stamped. The FACT-G measured the impact of cancer on four categories: Physical wellbeing, Social wellbeing, Emotional wellbeing and Functional wellbeing. Results: Compared to pegfilgrastim alone, patients on plinabulin + pegfilgrastim performed significantly better for Physical wellbeing on D8 and D15 of Cycle 2 (p < 0.0589 and p < 0.0039 respectively) and Cycle 3 (p < 0.0360 and p < 0.0343 respectively). Further analysis of the sub questions showed that both energy levels “I have a lack of energy” and pain”(I have pain” were significantly better for the plinabulin + pegfilgrastim combination versus pegfilgrastim alone (p < 0.0377 and p < 0.0420 respectively). Overall FACT-G completion compliance for the trial was 91%. Conclusions: The Physical wellbeing (in particular, pain and for energy levels) of patients receiving plinabulin in combination with pegfilgrastim for the prevention of TAC CIN, was significantly less impacted by chemo dosing compared to the pegfilgrastim alone arm. In addition, the results suggest that patients receiving the combination therapy recovered their pre-chemo Physical wellbeing levels more rapidly. Clinical trial information: NCT03531099.

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.
