Quality-adjusted time without symptoms of disease progression or toxicity of treatment in patients with primary advanced or recurrent endometrial cancer treated with dostarlimab plus carboplatin-paclitaxel versus carboplatin-paclitaxel
Bibliographic record
Abstract
OBJECTIVE: In part 1 of the phase 3 RUBY trial (NCT03981796) in patients with primary advanced or recurrent endometrial cancer, dostarlimab plus carboplatin-paclitaxel significantly improved progression-free and overall survival vs placebo plus carboplatin-paclitaxel. Post hoc analyses examined the impact of adding dostarlimab to chemotherapy, compared with placebo plus chemotherapy, on quality-adjusted time without symptoms of disease progression or toxicity of treatment in this patient population. METHODS: Patients were randomized 1:1 to receive dostarlimab/placebo plus chemotherapy every 3 weeks for 6 cycles, followed by dostarlimab/placebo monotherapy every 6 weeks for up to 3 years. Data from the first interim analysis (September 28, 2022) were used, and quality of life (QoL) was assessed with the EuroQoL 5-Dimensions 5-Level questionnaire. Quality-adjusted time without symptoms of disease progression or toxicity of treatment was calculated as the sum product of the restricted mean survival times spent in 3 mutually exclusive states: toxicity, time without symptoms of disease progression or treatment toxicity, and relapse, and utilized each state's corresponding QoL. RESULTS: In the dostarlimab and placebo arms, 241 and 246 patients were analyzed for safety, respectively. In the overall population, the mean (95% CI) duration of quality-adjusted time without symptoms of disease progression or toxicity of treatment was significantly longer in the dostarlimab arm (24.75 months [22.88 to 26.65 months]) than in the placebo arm (20.34 months [18.95 to 21.76 months]; the mean difference [95% CI] of 4.41 months [2.01 to 6.77 months], p < .001). Benefits in quality-adjusted time without symptoms of disease progression or toxicity of treatment after dostarlimab treatment were observed regardless of mismatch repair/microsatellite instability status or toxicity criteria used and were predominantly driven by the time without symptoms of disease. CONCLUSIONS: Dostarlimab plus carboplatin-paclitaxel treatment is associated with meaningful improvement in survival, avoidance of substantial toxicity, and maintenance of patient-reported QoL in patients with primary advanced or recurrent endometrial cancer.

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.
