Phase 2 Study of Zilovertamab Vedotin in Participants with Metastatic Solid Tumors.
Trial report in Cancer research communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04504916 (A Phase 2 Study of VLS-101 in Patients With Solid Tumors), which is not on this map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
purposeZilovertamab vedotin, an antibody-drug conjugate targeting receptor tyrosine kinase-like orphan receptor 1 (ROR1), had manageable safety and promising antitumor activity in participants with relapsed or refractory non-Hodgkin lymphomas. We evaluated zilovertamab vedotin in participants with previously treated metastatic solid tumors. PATIENTS AND
methodsThis phase 2, open-label, nonrandomized study (NCT04504916) enrolled participants with metastatic triple-negative breast cancer, hormone receptor-positive breast cancer, nonsquamous non-small-cell lung cancer, platinum-resistant ovarian cancer, or pancreatic cancer. Participants received zilovertamab vedotin ≤2.5 mg/kg once every 3 weeks (Q1/3W) or <1.75 mg/kg twice every 3 weeks (Q2/3W). The primary endpoint was objective response rate per RECIST version 1.1 by blinded independent central review. ROR1 protein expression was correlated with clinical outcomes.
resultsA total of 102 participants were enrolled (Q1/3W, n = 70; Q2/3W, n = 32). The objective response rate was 1% [95% confidence interval (CI), 0%-8%] with Q1/3W dosing (one partial response, hormone receptor-positive/HER2-negative breast cancer cohort) and 0% with Q2/3W dosing. The median progression-free survival (95% CI) was 2.3 (2.0-4.1) and 1.9 (1.7-2.1) months, respectively; the median overall survival (95% CI) was 8.3 (5.2-10.3) and 5.5 (4.4-11.0) months, respectively. Across dosing regimens, treatment-related adverse events were reported in 85 participants (83%), most commonly fatigue (29%) and nausea (28%). Treatment-related peripheral neuropathy occurred in 8%. Treatment-related adverse events led to dose interruption/reduction in 32 participants (31%) and permanent treatment discontinuation in 7 (7%). Tissue for ROR1 IHC was available on 17 participants, with only 3 (all nonresponders) showing ROR1 expression.
conclusionsZilovertamab vedotin had minimal antitumor activity, with only a single responder, and manageable safety in participants with previously treated metastatic solid tumors. SIGNIFICANCE: Zilovertamab vedotin had minimal antitumor activity and manageable safety in participants with previously treated metastatic solid tumors of various histologic subtypes. The results suggest that further development of zilovertamab vedotin in these solid tumors is not warranted.
