Safety and Efficacy of the First Subcutaneous ICI, Envafolimab, in the Treatment of Advanced Lung Cancer Patients: A Real-World Study.
Article in Thoracic cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundEnvafolimab is a novel immune checkpoint inhibitor (ICI) with several advantages due to its subcutaneous administration. Phases I and II randomized controlled trials have demonstrated promising efficacy in treating colorectal and gastric cancer. However, the safety and efficacy of Envafolimab in patients with advanced lung cancer remain to be investigated.
methodsThis retrospective, multicenter, open-label, single-arm cohort study examined real-world medical data from patients treated at four medical centers to assess the safety and efficacy of Envafolimab in treating patients with advanced lung cancer. The primary safety outcome was Envafolimab-related treatment-emergent adverse events (TEAEs) and immune-related adverse events (irAEs). The primary efficacy outcomes included overall survival (OS) and progression-free survival (PFS). Then, the relationship between clinical parameters and prognosis was investigated using univariate and multivariate regression analyses. Furthermore, the impact of tumor EGFR driver mutation status and PD-L1 expression on prognosis was explicitly explored in patients with nonsmall-cell lung cancer (NSCLC).
resultsThe cohort comprised 58 patients with a median follow-up time of 8.3 months (from March 1, 2022, to March 7, 2024). Envafolimab-related TEAEs and irAEs were observed in 53.4% and 27.6% of patients, respectively. No specific clinical factors were identified as being associated with irAEs. The median OS was 8.5 months (95% confidence interval [CI] 6.2-10.8), and the median PFS was 6.1 months (95% CI 3.8-8.3). For 47 patients with NSCLC, factors including ECOG PS > 2 (HR: 2.91, p = 0.015), Stage IV tumor (HR: 3.43, p = 0.043), and nonfirst-line Envafolimab treatment (HR: 3.27, p = 0.026) were associated with poor prognosis.
conclusionEnvafolimab demonstrates a tolerable safety profile and favorable efficacy. With its subcutaneous formulation, Envafolimab shows promising potential for treating advanced lung cancer.
