Objectives Identification of biomarkers associated with clinical benefit may be crucial in establishing optimal treatment choice for patients with squamous cell carcinoma (SCC) of the lung after first-line chemotherapy. In this study, the ability of the VeriStrat serum protein test to predict differential clinical benefit with afatinib versus erlotinib, and the association of VeriStrat status with clinical outcomes irrespective of EGFR-TKI used, was assessed in a retrospective analysis of the phase III LUX-Lung 8 trial. Materials and methods Pretreatment plasma samples were analyzed using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Spectra were evaluated to assign a VeriStrat ‘Good' (VS-G) or VeriStrat ‘Poor' (VS-P) classification. Overall survival (OS), progression-free survival, and other endpoints were assessed with respect to pretreatment VeriStrat status; OS was the primary efficacy variable. Results Of 795 patients randomized in LUX-Lung 8, 675 were classified (VS-G: 412; VS-P: 263). In the VS-G group, OS was significantly longer with afatinib versus erlotinib (HR 0.79 [95% CI: 0.63–0.98]). In the VS-P group, there was no significant difference in OS between afatinib and erlotinib (HR 0.90 [0.70–1.16]). However, there was no interaction between VeriStrat classification and treatment group for OS (p_interaction=0.5303). OS was significantly longer in VS-G versus VS-P patients, both in the overall VeriStrat-classified population (HR 0.41 [0.35–0.49]) and afatinib-treated patients (HR 0.40 [0.31–0.51]). Multivariate analysis showed that VeriStrat was an independent predictor of OS in afatinib-treated patients, regardless of ECOG PS or best response to first-line chemotherapy. Outcomes with other efficacy endpoints were similar. Conclusion VS-G classification is strongly associated with favorable survival outcomes with either afatinib or erlotinib compared with VS-P classification. In VS-G patients, survival outcomes with afatinib are superior to those with erlotinib. VeriStrat classification may guide treatment decisions in patients with SCC of the lung.

Background and Objectives: CRC is one of the leading causes of cancer-related deaths worldwide. New biomarkers are needed to identify the high-risk patient population after primary treatment and to personalize and perfect treatment and follow-up. Indicators of cancer-associated systemic inflammatory response, such as the LMR, have been widely investigated and have yielded conflicting results. The aim of this study was to investigate the effect of preoperative LMR on the prognosis of recurrent CRC. Materials and Methods: We included 204 patients admitted to our center for recurrent CRC between January 2010 and January 2015. Retrospectively, we investigated the preoperative LMR data and its effect on RFS and OS. Results: The cut-off value of LMR was 24.72 and, according to this value, we created two groups: LMR-H and LMR-L. There were 104 (50.9%) patients in the H group and 100 (49.1%) patients in the L group. The median OS was 38.0 months (95% confidence interval (CI): 30.66–45.33) for the L group and 49.0 months (95% CI: 44.06–53.94) for the H group. Overall population median OS was calculated as 44.0 months (95% CI: 40.1–47.8, p = 0.004). Median RFS was 21.3 months (95% CI: 18.3–24.2) for the LMR-L group and 28.39 months (95% CI: 24.9–31.8) for the LMR-H group (p = 0.004). Conclusions: The association between the LMR at diagnosis and early recurrence, as well as survival outcomes, was investigated in patients with recurrent CRC. Higher preoperative LMR levels were found to correlate with improved OS and RFS.

Background: Non-small cell lung cancer (NSCLC) is often diagnosed late with many patients (pts) not responding to first line therapy or only responding for a limited time. BNT116 is an intravenously administered uridine RNA-based lipoplex cancer vaccine comprising six mRNAs (MAGE A3, CLDN6, KK-LC-1, PRAME, MAGE A4, MAGE C1), each encoding a tumor-associated antigen (TAA) frequently expressed in NSCLC. Here, we present preliminary results from pts with advanced unresectable or metastatic NSCLC (ECOG 0-1) receiving BNT116 + docetaxel (DTX). Methods: LuCa-MERIT-1 (NCT: 05142189, EudraCT: 2021-004739-94) is a first-in-human, open label, Phase I trial to determine safety (dose limiting toxicities [DLTs]; treatment-emergent adverse events [TEAEs]) and clinical activity (RECIST v1.1) of BNT116 alone or in combinations. The cohort reported here will inform the dose of BNT116 in combination with DTX. Pts must have progressed on PD-1/PD-L1 inhibitor and a platinum-based chemotherapy. Biomarker analysis includes e.g., immunogenicity (ELISpot, n=3), cytokines (MSD, n=20), ctDNA (Avenio ctDNA Surveillance, n=~20), and PD-L1 (IHC, n=20). Results: As of 01 DEC 2023, 20 pts (median age 66 years) have received BNT116 in addition to DTX at 75 mg/m2 Q3W. The combination demonstrated a manageable safety profile. All pts experienced at least one TEAE. TEAEs ≥Grade 3/4, (incidence rate ≥10%) include neutropenia (n=10 [50%]), pneumonia (n=3 [15%]), hypertension (n=3 [15%]), lymphocyte count decreased, diarrhea, and fatigue (each n=2 [10%]). Serious TEAEs were observed in ten pts (50%), of which three were considered as related to BNT116 (Grade 3 cytokine release syndrome, Grade 3 bronchospasm, and Grade 3 pyrexia) and three were considered as related to DTX (Grade 3 diarrhea, Grade 3 rash, and Grade 4 febrile neutropenia). No DLTs within the dose confirmation period or deaths under treatment were observed. Seven of 20 pts (35%) had a partial response, 10 of 20 pts (50%) had stable disease. The objective response rate was 35% (95% CI: 15.4-59.2) and the disease control rate was 85% (95% CI: 62.1-96.8). Robust antigen-specific T-cell responses and cytokine induction were observed even with the addition of DTX and the use of prophylactic dexamethasone on Day 2 of each cycle. Conclusions: BNT116 + DTX shows encouraging antitumor activity, consistent induction of immune responses, a manageable safety profile, and no signs of additive toxicity. Updated safety and clinical activity data will be presented along with additional biomarker data.
