1 · What the graph read from 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.

2 · The registry

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

aimAvelumab first-line (1L) maintenance was approved for treatment of advanced urothelial carcinoma (UC) based on results from the JAVELIN Bladder 100 Phase 3 trial. We report real-world data from an early access program (EAP) for avelumab 1L maintenance treatment in Malaysia.

methodsData from patients with locally advanced or metastatic UC who received ≥ 1 dose of avelumab 1L maintenance treatment between September 2021 and January 2023 were obtained retrospectively. Patient and treatment characteristics, best response to treatment, and safety were assessed.

resultsData were provided from 13 patients treated at 9 hospitals in Malaysia. Seven patients (53.8%) were female, and ECOG performance status prior to 1L chemotherapy was 0-1 in 11 patients (84.6%) and 2 in 2 patients (15.4%). Chemotherapy included cisplatin in 6 patients (46.2%) and carboplatin in 7 patients (53.8%), and the best response was complete response in 1 patient (7.7%), partial response in 7 patients (53.8%), and stable disease in 5 patients (38.5%). The median duration of avelumab treatment was 9 months, with treatment ongoing in 4 patients (30.8%) at last follow-up. The objective response rate was 30.8% and an additional 5 patients (38.5%) had stable disease as the best response. Median PFS was 10.4 months. Reasons for discontinuation were disease progression in 8 patients (61.5%) and patient withdrawal in 1 patient (7.7%). Treatment-related adverse events occurred in 3 patients (23.1%) and were grade 2 in 1 patient (7.7%) and grade 1 in 2 (15.4%).

conclusionsData from this small EAP population support the use of avelumab 1L maintenance treatment in patients with advanced UC in Malaysia.
