The EU-funded I3LUNG Project: Integrative Science, Intelligent Data Platform for Individualized LUNG Cancer Care With Immunotherapy.

Although immunotherapy (IO) has changed the paradigm for the treatment of patients with advanced non-small cell lung cancers (aNSCLC), only around 30% to 50% of treated patients experience a long-term benefit from IO. Furthermore, the identification of the 30 to 50% of patients who respond remains a major challenge, as programmed Death-Ligand 1 (PD-L1) is currently the only biomarker used to predict the outcome of IO in NSCLC patients despite its limited efficacy. Considering the dynamic complexity of the immune system-tumor microenvironment (TME) and its interaction with the host's and patient's behavior, it is unlikely that a single biomarker will accurately predict a patient's outcomes. In this scenario, Artificial Intelligence (AI) and Machine Learning (ML) are becoming essential to the development of powerful decision-making tools that are able to deal with this high-complexity and provide individualized predictions to better match treatments to individual patients and thus improve patient outcomes and reduce the economic burden of aNSCLC on healthcare systems. I3LUNG is an international, multicenter, retrospective and prospective, observational study of patients with aNSCLC treated with IO, entirely funded by European Union (EU) under the Horizon 2020 (H2020) program. Using AI-based tools, the aim of this study is to promote individualized treatment in aNSCLC, with the goals of improving survival and quality of life, minimizing or preventing undue toxicity and promoting efficient resource allocation. The final objective of the project is the construction of a novel, integrated, AI-assisted data storage and elaboration platform to guide IO administration in aNSCLC, ensuring easy access and cost-effective use by healthcare providers and patients.

Design and Rationale of the HANSE Study: A Holistic German Lung Cancer Screening Trial Using Low-Dose Computed Tomography.

Despite the high prevalence and mortality of lung cancer and proven effectiveness of low-dose computed tomography (LDCT) to reduce mortality, Germany still lacks a national screening program. The German Institute for Quality and Efficiency in Health Care (IQWiG) and the Federal Office for Radiation Protection (BfS) both published positive scientific evaluations recommending a quality-controlled national screening program. IQWiG underlined the importance of a clear risk definition, integrated smoking cessation programs, and quality assurance, highlighting the necessity of procedural optimization.In the HANSE study, former and current smokers aged 55-79 years are assessed for their lung cancer risk by the NELSON and PLCOM2012 risk scores. 5000 high-risk participants, defined as PLCOM2012 6-year risk ≥ 1.58 % or fulfilling NELSON risk inclusion criteria, will be screened by LDCT at baseline and after 12 months. Lung nodules are analyzed by a modified Lung-RADS 1.1 score of the HANSE study, and values of emphysema and coronary calcium are determined and randomly reported to the participants. 7100 low-risk participants serve as a control. All patients are followed-up for up to 10 years. The sensitivity and specificity of the two risk assessments and LDCT screening, effects of the randomized LDCT reporting, efficiency of lung nodule management, and several other factors are assessed to analyze the success and quality of the holistic screening program.The HANSE study is designed as a holistic lung cancer screening study in northern Germany to answer pressing questions for a successful implementation of an effective German lung cancer screening program. · HANSE is designed to address pressing questions for the implementation of lung cancer screening in Germany.. · HANSE compares NELSON and PLCOM2012 risk assessments for optimal definition of the high-risk group. . · HANSE integrates cardiac calcium and pulmonary emphysema scoring in a holistic screening approach..

Plasma biomarkers correlating with clinical outcome in a phase II study of sorafenib in advanced NSCLC.

We investigated the relationship between plasma protein biomarker concentrations and clinical outcomes in 52 patients with relapsed/refractory advanced non-small cell lung cancer (NSCLC) treated with 400~mg bid sorafenib in a phase II trial. Blood samples were collected at baseline, on day 15 of cycle 1 (C1D15), and on day 1 of cycle 3 (C3D1), and plasma concentrations of total VEGF, VEGF-165, soluble (s) VEGFR-2, PDGF-BB, sPDGFR-ß, sEGFR, sHER-2, uPA, PAI-1, uPAR, TIMP-1, and circulating Ras p21 were assayed by ELISA. Elevated baseline VEGF, VEGF-165, PDGF-BB, Ras p21, and TIMP-1 concentrations were associated with poorer patient outcomes (shorter overall survival [OS] and/or progression-free survival [PFS]). During treatment, the mean concentrations of sVEGFR-2, PDGF-BB, sPDGFR-ß, TIMP-1, uPAR, and PAI-1 decreased, while the mean sEGFR concentration increased. Increases in VEGF, VEGF-165, PDGF-BB, and TIMP-1 during treatment were associated with better outcomes (longer OS and/or PFS), whereas increases in plasma Ras p21 during treatment were associated with shorter PFS. The associations between baseline concentrations and/or pharmacodynamic changes in plasma proteins and clinical outcomes in NSCLC patients treated with sorafenib suggest that these biomarkers may have a prognostic role and/or predict the efficacy of sorafenib in patients with NSCLC.

Phase III study of carboplatin and paclitaxel alone or with sorafenib in advanced non-small-cell lung cancer.

PURPOSE This phase III, multicenter, randomized, placebo-controlled trial assessed the efficacy and safety of sorafenib, an oral multikinase inhibitor, in combination with carboplatin and paclitaxel in chemotherapy-naïve patients with unresectable stage IIIB or IV non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Nine hundred twenty-six patients were randomly assigned to receive up to six 21-day cycles of carboplatin area under the curve 6 and paclitaxel 200 mg/m(2) (CP) on day 1, followed by either sorafenib 400 mg twice a day (n = 464, arm A) or placebo (n = 462, arm B) on days 2 to 19. The maintenance phase after CP consisted of sorafenib 400 mg or placebo twice a day. The primary end point was overall survival (OS); secondary end points included progression-free survival and tumor response. RESULTS Overall demographics were balanced between arms; 223 patients (24%) had squamous cell histology. On the basis of a planned interim analysis, median OS was 10.7 months in arm A and 10.6 months in arm B (hazard ratio [HR] = 1.15; 95% CI, 0.94 to 1.41; P = .915). The study was terminated after the interim analysis concluded that the study was highly unlikely to meet its primary end point. A prespecified exploratory analysis revealed that patients with squamous cell histology had greater mortality in arm A than in arm B (HR = 1.85; 95% CI, 1.22 to 2.81). Main grade 3 or 4 sorafenib-related toxicities included rash (8.4%), hand-foot skin reaction (7.8%), and diarrhea (3.5%). CONCLUSION No clinical benefit was observed from adding sorafenib to CP chemotherapy as first-line treatment for NSCLC.

Phase II, double-blinded, randomized study of enzastaurin plus pemetrexed as second-line therapy in patients with advanced non-small cell lung cancer.

INTRODUCTION: We examined the efficacy of enzastaurin plus pemetrexed as second-line therapy in patients with advanced (stage IIIA/B or IV) non-small cell lung cancer in a double-blinded, randomized, phase II study. METHODS: Patients received pemetrexed 500 mg/m intravenously on day 1 of 21-day cycles (day 8 in cycle 1) plus oral enzastaurin (250 mg two times per day; combination arm) or placebo (pemetrexed arm). Both arms received supplementation with vitamin B12, folic acid, and dexamethasone. An interim analysis was conducted to determine whether efficacy would warrant a phase III study. RESULTS: The interim analysis showed no evidence of improved progression-free survival with enzastaurin. At final analysis (N = 160, 80 in each arm), baseline characteristics were well balanced. There was no significant difference in progression-free survival (3.0 months, p = 0.544) or overall survival (9.6 months in combination arm and 7.4 months in pemetrexed arm, p = 0.171). Drug-related serious adverse events included cerebrovascular accident, palpitations, and renal failure (n = 1, each) in combination arm and neutropenic sepsis, thrombocytopenia, and panniculitis (n = 1, each) in pemetrexed arm. Nonhematologic drug-related grade 3/4 toxicities were similar in both arms. Grade 3/4 hematologic toxicities were higher with the combination, specifically leukopenia (6.3% versus 0%), neutropenia (15.2% versus 5.0%), and thrombocytopenia (8.9% versus 1.3%). Of the 26 deaths reported on-study or within 30 days of discontinuation (10 in combination arm and 16 in pemetrexed arm), none were drug related. CONCLUSION: The combination regimen of enzastaurin and pemetrexed is well tolerated but does not improve efficacy over pemetrexed and placebo as second-line treatment of unselected patients with advanced non-small cell lung cancer.

Phase II, multicenter, uncontrolled trial of single-agent sorafenib in patients with relapsed or refractory, advanced non-small-cell lung cancer.

PURPOSE: Sorafenib is an oral multikinase inhibitor that targets the Ras/Raf/MEK/ERK mitogenic signaling pathway and the angiogenic receptor tyrosine kinases, vascular endothelial growth factor receptor 2 and platelet-derived growth factor receptor beta. We evaluated the antitumor response and tolerability of sorafenib in patients with relapsed or refractory, advanced non-small-cell lung cancer (NSCLC), most of whom had received prior platinum-based chemotherapy. PATIENTS AND METHODS: This was a phase II, single-arm, multicenter study. Patients with relapsed or refractory advanced NSCLC received sorafenib 400 mg orally twice daily until tumor progression or an unacceptable drug-related toxicity occurred. The primary objective was to measure response rate. RESULTS: Of 54 patients enrolled, 52 received sorafenib. The predominant histologies were adenocarcinoma (54%) and squamous cell carcinoma (31%). No complete or partial responses were observed. Stable disease (SD) was achieved in 30 (59%) of the 51 patients who were evaluable for efficacy. Four patients with SD developed tumor cavitation. Median progression-free survival (PFS) was 2.7 months, and median overall survival was 6.7 months. Patients with SD had a median PFS of 5.5 months. Major grades 3 to 4, treatment-related toxicities included hand-foot skin reaction (10%), hypertension (4%), fatigue (2%), and diarrhea (2%). Nine patients died within a 30-day period after discontinuing sorafenib, and one patient experienced pulmonary hemorrhage that was considered drug related. CONCLUSION Continuous treatment with sorafenib 400 mg twice daily was associated with disease stabilization in patients with advanced NSCLC. The broad activity of sorafenib and its acceptable toxicity profile suggest that additional investigation of sorafenib as therapy for patients with NSCLC is warranted.

A phase II pharmacodynamic study of erlotinib in patients with advanced non-small cell lung cancer previously treated with platinum-based chemotherapy.

PURPOSE: To examine potential markers of clinical benefit and the effects of erlotinib on the epidermal growth factor receptor (EGFR) signaling pathway in advanced non-small cell lung cancer patients refractory to platinum-based chemotherapy. EXPERIMENTAL DESIGN: Patients were given erlotinib (150 mg/d). Tumor biopsies were done immediately before treatment and in a subgroup of patients after 6 weeks' treatment. RESULTS: Of 73 evaluable patients, 7 (10%) had partial response and 28 (38%) had stable disease. In 53 patients with baseline tumor samples, no relationship was observed between pretreatment levels of EGFR, phosphorylated (p)-EGFR, p-AKT, p-mitogen-activated protein kinase (MAPK), or p27 and clinical benefit (i.e., response, or stable disease >/=12 weeks). Tumors from 15 of 57 patients had high EGFR gene copy number, assessed using fluorescence in situ hybridization (FISH positive), 10 of whom had clinical benefit, compared with 5 of 42 FISH-negative patients. FISH-positive patients had longer median progression-free [137 versus 43 days, P = 0.002; hazard ratio (HR), 0.37] and overall (226 versus 106 days, P = 0.267; HR, 0.70) survival than FISH-negative patients. In paired biopsy samples from 14 patients, p-EGFR (P = 0.002), p-MAPK (P = 0.001), and Ki-67 (P = 0.025) levels were significantly reduced after 6 weeks' treatment. Apoptosis was significantly increased in patients with clinical benefit (P = 0.029), and may be a marker of clinical benefit. CONCLUSION: In this study, EGFR FISH-positive status was associated with improved outcome after erlotinib therapy. Erlotinib led to reduced levels of p-EGFR, p-MAPK, and Ki-67, and stimulated apoptosis in tumor samples from patients with clinical benefit.

Single-agent pemetrexed or sequential pemetrexed/gemcitabine as front-line treatment of advanced non-small cell lung cancer in elderly patients or patients ineligible for platinum-based chemotherapy: a multicenter, randomized, phase II trial.

INTRODUCTION: This randomized phase II trial evaluated single-agent pemetrexed or sequential pemetrexed/gemcitabine in patients with non-small cell lung cancer (NSCLC) who were elderly (> or = 70 years) or younger than 70 years and ineligible for platinum-based chemotherapy. METHODS: Chemonaive patients with stage IIIB/IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 2 received either 500 mg/m2 of pemetrexed (day 1, every 3 weeks) for eight cycles, or the same dosage of pemetrexed for cycles 1 and 2 and then 1200 mg/m2 of gemcitabine (days 1 and 8, every 3 weeks) for cycles 3 and 4 (repeated once for a total of eight cycles). All patients were given vitamin B12 and folic acid supplementation. RESULTS: From July 2003 to July 2004, 87 patients (44 pemetrexed; 43 pemetrexed/gemcitabine) received treatment. The median time to progression was 4.5 (95% confidence interval: 3.0-9.3) and 4.1 months (95% confidence interval: 1.7-5.8) for the pemetrexed and pemetrexed/gemcitabine arms, respectively, and the median progression-free survival time was 3.3 months for both arms. Tumor response rates for the pemetrexed and pemetrexed/gemcitabine arms were 4.5% and 11.6%, respectively. The median overall survival time was 4.7 months for the pemetrexed arm and 5.4 months for the pemetrexed/gemcitabine arm, with respective 1-year survival rates of 28.5% and 28.1%. Grade 3/4 hematologic toxicity consisted of neutropenia (4.5% pemetrexed; 2.3% pemetrexed/gemcitabine), febrile neutropenia (4.5% pemetrexed; 4.7% pemetrexed/gemcitabine), thrombocytopenia (4.5% pemetrexed; 7.0% pemetrexed/gemcitabine), and anemia (6.8% pemetrexed; 4.7% pemetrexed/gemcitabine). No grade 3/4 nonhematologic toxicities exceeded 4.7% in either arm. CONCLUSIONS: Single-agent pemetrexed and sequential pemetrexed/gemcitabine have shown moderate activity and are well tolerated as first-line treatments for advanced NSCLC in elderly patients or patients unsuitable for platinum-based combination chemotherapy.
