Quality of life, functioning, and symptoms in patients with previously treated locally advanced or metastatic urothelial carcinoma from EV-301: A randomized phase 3 trial of enfortumab vedotin versus chemotherapy.
Bibliographic record
Abstract
4539 Background: In EV-301, a randomized, open-label phase 3 study (NCT03474107), enfortumab vedotin (EV), a Nectin-4–directed therapy, significantly prolonged median overall survival by ̃3.9 months and reduced the risk of death by 30% compared with standard chemotherapy (SC; docetaxel, paclitaxel, or vinflunine) in patients with previously treated locally advanced/metastatic urothelial carcinoma. Understanding patient perspectives and experiences is important to further contextualize the benefits/risks of EV. Here, we report key prespecified quality-of-life (QoL) endpoints, a secondary objective of EV-301. Methods: Patients completed the validated European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire Core 30 (QLQ-C30) at baseline, on Day 1 of each week for the first 12 weeks, and then every 12 weeks until discontinuation. The QLQ-C30 assessed functional domains, symptom scales/items, financial impact, and overall health/QoL. Descriptive statistics were used to summarize instrument compliance rates and scores; mixed model repeated measures were used to evaluate changes from baseline over time. Logistic regressions were conducted to assess confirmed improvement rates, defined as clinically meaningful improvement (predefined per domain) over two subsequent visits. Results: Of the 608 randomized patients (EV, n = 301; SC, n = 307), 77.3% were male, median age was 68 (range: 30-88), and 30.9% had liver metastasis. Questionnaire compliance rates at baseline were ̃90% in both groups; during the study, average rates were 70.2% (EV) and 66.9% (SC). Baseline QLQ-C30 scores were similar between groups. At Week 12, scores on the global health status (GHS) scale were similar between groups (EV: -2.8, SC: -5.0; P=.2429), but SC was associated with numerically greater deterioration and more variability in QoL over the first 12 weeks. Patients receiving EV had significant reduction in pain symptoms (EV: -5.62, SC: +0.11; adjusted difference: -5.73, P<.05), but significant worsening of appetite loss (EV: +8.55, SC: +1.26; adjusted difference: 7.29, P<.05) compared with SC. Other symptom scores were not significantly different between groups. Higher proportions of patients on EV vs SC had significant confirmed improvements across all functioning domains (role, physical, emotional, social, cognitive), GHS, and several symptom scales (pain, fatigue, dyspnea, constipation). The greatest difference in improvement was reported for pain (EV: 51.6%, SC: 28.8%; OR = 2.76[1.81, 4.22]). Conclusions: Compared with SC, patients receiving EV had numerically less deterioration and variability in QoL during the first 12 weeks of treatment. More patients in the EV group had improvements over SC in 10 of 15 QLQ-C30 domains; improvement in pain showed the largest benefit. Clinical trial information: NCT03474107.

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.
