Background: Patient-reported outcomes were evaluated in EPCORE NHL-1 in patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) treated with epcoritamab monotherapy (NCT03625037). Materials and Methods: Adults with R/R CD20+ LBCL and ≥2 prior systemic antilymphoma therapies, including anti-CD20, completed the Functional Assessment of Cancer Therapy–Lymphoma (FACT-Lym) and EQ-5D-3L. A subgroup of patients provided additional feedback in one-on-one qualitative interviews. FACT-Lym and EQ-5D-3L score changes from baseline (CFB) to cycle 9 or end of treatment were interpreted using published minimally important differences (MID). Results: In total, 157 patients (88.5% with diffuse LBCL) were treated (median age, 64 years). In total, 70.7% had ≥3 prior treatments, 61.1% had primary refractory disease, and 82.8% were refractory to last systemic therapy. FACT-Lym scores exceeded MID thresholds: mean (SD) CFB were 4.4 (15.2), MID 3.0 to 7.0 (FACT-General); 5.9 (7.6), MID 2.9 to 5.4 (FACT-Lymphoma subscale); 8.4 (15.2), MID 5.5 to 11.0 (FACT-Trial Outcome Index); 10.3 (20.2), MID 6.5 to 11.2 (FACT-Lym total score). EQ-5D-3L index scores, 0.09 (0.20), MID 0.08, and EQ-VAS scores, 16.6 (22.8), MID 7.0, improved. In 20 qualitative interviews, 88.2% reported symptom improvements; 80.0% were “very satisfied” or “satisfied” with epcoritamab. Conclusions: R/R LBCL patients reported consistent, clinically meaningful improvements in symptoms and HRQoL and satisfaction with epcoritamab.
