Efficacy and Safety of Glofitamab Plus Polatuzumab Vedotin in Relapsed/Refractory Large B-Cell Lymphoma Including High-Grade B-Cell Lymphoma: Results From a Phase Ib/II Trial.
Trial report in Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03533283 (An Open-Label, Multi-Center, Phase IB/II Study of Glofitamab and Atezolizumab or Polatuzumab Vedotin), which is not on this map. Cited by 13 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
purposeAn unmet need remains for more effective therapies for relapsed/refractory (R/R) large B-cell lymphoma (LBCL), especially high-grade B-cell lymphoma (HGBCL). We present the primary analysis of a phase Ib/II study (ClinicalTrials.gov identifier: NCT03533283) investigating efficacy and safety of glofitamab plus polatuzumab vedotin (Glofit-Pola) in patients with R/R LBCL, including HGBCL and those who received previous chimeric antigen receptor (CAR) T-cell therapy.
methodsPatients received 1,000 mg obinutuzumab on Cycle (C)1 Day (D)1 (once daily). Polatuzumab vedotin (1.8 mg/kg) was given on C1D2 and D1 of C2-6 (21-day cycles; once daily). Glofitamab was given as step-up doses in C1 (D8, 2.5 mg; D15, 10 mg) followed by 30 mg on D1 of C2-12 (21-day cycles; once daily). Polatuzumab vedotin was given for six fixed-duration cycles, and glofitamab for 12.
resultsAs of September 2, 2024, 129 patients with LBCL (HGBCL; n = 44, 34.1%), received ≥1 dose of study treatment. The median age was 67 years (range, 23-84), and 63.6% were male. Patients had received a median of 2 (range, 1-7) previous lines of treatment (previous CAR T-cell therapy, n = 28, 21.7%). The independent review committee-assessed overall response rate was 78.3% (complete response rate, 59.7%). The median progression-free survival and overall survival (OS) were 12.3 and 33.8 months, respectively (median OS follow-up time, 32.7 months). The most common adverse event (AE) was cytokine release syndrome (43.4%; grade 1-2: 41.9%; one grade 5 event). Grade 3-4 AEs occurred in 58.9% of patients; 9.3% had grade 5 AEs, and 14.7% discontinued treatment because of AEs.
conclusionGlofit-Pola demonstrated high efficacy and durable responses, with manageable safety, in heavily pretreated patients with R/R LBCL, including patients with HGBCL and previous CAR T-cell therapy failure.
