Atrasentan in Patients With Advanced Renal Cell Carcinoma: A Phase 2 Trial of the ECOG-ACRIN Cancer Research Group (E6800).
Trial report in Clinical genitourinary cancer, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAtrasentan, an oral endothelin receptor A antagonist, demonstrated phase 1 activity in patients with renal cell carcinoma (RCC). A phase 2 study was undertaken in patients with measurable or bone-only metastatic RCC in the pre-VEGF/TKI era. METHODS AND MATERIALS: Patients were stratified by disease status and prior immunotherapy. Eligible patients had no prior chemotherapy, 0 to 1 prior immunotherapies, and an Eastern Cooperative Oncology Group performance status of 0 to 2. Patients received atrasentan 10 mg per day until progression. The primary end point was progression-free (PF) rate at 6 months. Rates of 25% among patients treated with prior immunotherapy and 45% among patients with no prior immunotherapy were considered promising. A 2-stage design was used for cohorts without prior immunotherapy.
resultsFrom 2003 to 2005, 98 patients were registered. Median treatment duration was 9.9 weeks (range, 0.3-107 weeks). Toxicities were mild; 71% of patients reported no grade 3 or higher treatment-related events. Grade 4 events included neutropenia (n = 3), dyspnea (n = 2), thrombosis (n = 1), and arrhythmia (n = 1). Two grade 5 events (dyspnea and constitutional) were possibly treatment related. Six-month PF rates (90% confidence interval) were 14% (6-25), 0% (0-39), 8% (1-23), and 22% (8-44), respectively, for patients with prior immunotherapy/measurable disease (n = 44), prior immunotherapy/bone metastases (n = 6), no prior immunotherapy/measurable disease (n = 25), and no prior immunotherapy/bone metastases (n = 18). Median PF survival was 2.3 months (95% confidence interval, 2.0-3.5 months).
conclusionAlthough well tolerated, atrasentan did not yield 6-month PF rates supporting its use as first-line monotherapy in patients with advanced RCC.
