Personalized tumor-loaded monocyte-derived dendritic cell vaccination in combination with atezolizumab as maintenance treatment in extensive-stage small cell lung cancer (ES-SCLC): phase Ib-II VENEZOLUNG trial.
Trial report in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04487756 (Phase Ib/II Trial of the Combination of Atezolizumab With Dendritic Cell Vaccination as Maintenance Treatment in Patients With Extensive Stage Small Cell Lung Cancer), which is not on this map.

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.

Abstract
backgroundDespite the incorporation of atezolizumab, an anti-programmed death-ligand 1 (PD-L1) antibody, into first-line chemotherapy regimen, survival in patients with extensive-stage small cell lung cancer (ES-SCLC) remains poor. Given the role of dendritic cells (DCs) in modulating responses to anti-programmed cell death protein 1 (PD-1) antibodies, a promising avenue is the development of vaccines based on DCs, together with the evaluation of how DC phenotypic modifications shape treatment efficacy. MATERIALS AND
methodsThis is a single-arm, phase Ib/II, open-label clinical trial investigating the safety and activity of combining autologous tumor lysate pulsed DCs administered intradermally with intravenous atezolizumab as maintenance therapy for patients with ES-SCLC. Following leukapheresis, monocytes were differentiated ex vivo into mature DCs and loaded with irradiated autologous tumor lysate. After standard induction therapy (four cycles of carboplatin, etoposide, and atezolizumab), patients received up to six doses of mature DCs intradermally, along with intravenous atezolizumab 1,200 mg every 3 weeks, until disease progression.
results20 patients were enrolled, including six patients with brain metastases. 18 patients received DC vaccination, with a median of three doses (range 1-6). Most grade 3-4 treatment-related adverse events were hematological and related to chemotherapy. DC vaccination was well tolerated, with only grade 1-2 transient skin irritation at the injection site. Among 18 evaluable patients, 17 (94.4%) achieved an objective response. After a median follow-up of 31.4 months, progression-free survival at 2 years (PFS
conclusionDC immunization combined with atezolizumab maintenance following standard chemotherapy plus atezolizumab treatment is well tolerated. Its clinical activity cannot be definitively determined in this study, as it was administered as maintenance therapy; however, the observed rate of long-term survivors suggests a potential benefit. Our findings suggest a pivotal role for cDC1s in mediating the antitumor activity in long-term survivors. TRIAL REGISTRATION NUMBER: NCT04487756.
