Trial reportCancer2017
Bevacizumab alone or in combination with TRC105 for patients with refractory metastatic renal cell cancer.
Trial report in Cancer, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTargeting the vascular endothelial growth factor (VEGF) pathway has improved outcomes in metastatic renal cell carcinoma (RCC); however, resistance inevitably occurs. CD105 (endoglin) is an angiogenic pathway that is strongly upregulated after VEGF inhibition, potentially contributing to resistance. The authors tested whether TRC105, a monoclonal antibody against endoglin, impacted disease control in patients with previously treated RCC who were receiving bevacizumab.
methodsEligible patients with metastatic RCC who had previously received 1 to 4 prior lines of therapy, including VEGF-targeted agents, were randomized 1:1 to receive bevacizumab 10 mg/kg intravenously every 2 weeks (arm A) or the same plus TRC105 10 mg/kg intravenously every 2 weeks (arm B). The primary endpoint was progression-free survival (PFS) at 12 and 24 weeks. Correlative studies included serum transforming growth factor β (TGFβ) and CD105 levels as well as tissue immunostaining for TGFβ receptors.
resultsFifty-nine patients were enrolled (28 on arm A and 31 on arm B), and 1 patient on each arm had a confirmed partial response. The median PFS for bevacizumab alone was 4.6 months compared with 2.8 for bevacizumab plus TRC105 (P = .09). Grade ≥ 3 toxicities occurred in 16 patients (57%) who received bevacizumab compared with 19 (61%) who received bevacizumab plus TRC105 (P = .9). Baseline serum TGFβ levels below the median (<10.6 ng/mL) were associated with longer median PFS (5.6 vs 2.1 months; P = .014).
conclusionsTRC105 failed to improve PFS when added to bevacizumab. TGFβ warrants further study as a biomarker in RCC. Cancer 2017;123:4566-4573. © 2017 American Cancer Society.
