First-Line Treatment with Tivozanib for Metastatic Renal Cell Carcinoma in Real-World Settings Across Germany: Results of the Prospective, Non-Interventional, Post-Approval Study T-Rex.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe efficacy and safety of tivozanib for the treatment of advanced or metastatic renal cell carcinoma (mRCC) have been established in the first-line setting in the Phase III trial TIVO-1.
methodsThe prospective T-Rex study conducted in German clinical practice evaluated the safety, effectiveness and impact on quality of life (QoL) of first-line treatment with tivozanib in 32 patients with mRCC recruited between May 2019 and April 2021.
resultsRecruited patients were predominantly elderly, with 53.1% aged over 75 years. Patients received a median of 6.5 tivozanib treatment cycles and the median time on treatment was 5.7 months. Overall, 78.1% of patients experienced treatment-related adverse events, including diarrhea, nausea and hypotension/hypertension. A clinical (i.e., complete or partial) response was observed in 46.9% of patients. Patients' QoL remained stable from baseline to the end of treatment and most symptomatic toxicities resolved by the final treatment cycle, with the exclusion of dry skin, itching, and hand-foot syndrome.
conclusionsThese data demonstrate that first-line treatment with tivozanib was associated with clinical activity, favorable tolerability, and stable QoL in patients with mRCC treated in everyday clinical practice across Germany, including those with advanced age.
