INTRODUCTION: We assessed the Aurora A kinase inhibitor, alisertib, plus paclitaxel (henceforth referred to as alisertib/paclitaxel) as second-line treatment for SCLC. METHODS: In this double-blind study, patients with relapsed or refractory SCLC were stratified by relapse type (sensitive versus resistant or refractory) and brain metastases and randomized 1:1 to alisertib/paclitaxel or placebo plus paclitaxel (henceforth referred to as placebo/paclitaxel) in 28-day cycles. The primary end point was progression-free survival (PFS). Associations of c-Myc expression in tumor tissue (prespecified) and genetic alterations in circulating tumor DNA (retrospective) with clinical outcome were evaluated. RESULTS: A total of 178 patients were enrolled (89 in each arm). The median PFS was 3.32 months with alisertib/paclitaxel versus 2.17 months with placebo/paclitaxel (hazard ratio [HR] = 0.77, 95% confidence limit [CI]: 0.557-1.067, p = 0.113 in the intent-to-treat population versus HR = 0.71, 95% CI: 0.509-0.985, p = 0.038 with corrected analysis applied). Among 140 patients with genetic alternations, patients with cell cycle regulator mutations (cyclin-dependent kinase 6 gene [CDK6], retinoblastoma-like 1 gene [RBL1], retinoblastoma-like 2 gene [RBL2], and retinoblastoma 1 gene [RB1]) had significantly improved PFS with alisertib/paclitaxel versus with placebo/paclitaxel (3.68 versus 1.80 months, respectively [HR = 0.395, 95% CI: 0.239-0.654, p = 0.0003]), and overall survival (7.20 versus 4.47 months, respectively [HR = 0.427, 95% CI: 0.259-0.704, p = 0.00085]). A subset of patients with c-Myc expression showed significantly improved PFS with alisertib/paclitaxel. The incidence of grade 3 or higher drug-related adverse events was 67% (58 patients) with alisertib/paclitaxel versus 22% (25 patients) with placebo/paclitaxel. Twelve patients (14%) versus 11 (12%) died on study, including four versus zero treatment-related deaths. CONCLUSIONS: Efficacy signals were seen with alisertib/paclitaxel in relapsed or refractory SCLC. c-Myc expression and mutations in cell cycle regulators may be potential predictive biomarkers of alisertib efficacy; further prospective validations are warranted.

INTRODUCTION: This study evaluated noninferiority of darbepoetin alfa versus placebo for overall survival (OS) and progression-free survival (PFS) in anemic patients with NSCLC treated to a 12.0-g/dL hemoglobin (Hb) ceiling. METHODS: Adults with stage IV NSCLC expected to receive two or more cycles of myelosuppressive chemotherapy and Hb less than or equal to 11.0 g/dL were randomized 2:1 to blinded 500 μg darbepoetin alfa or placebo every 3 weeks. The primary endpoint was OS; a stratified Cox proportional hazards model was used to evaluate noninferiority (upper confidence limit for hazard ratio [HR] < 1.15). Secondary endpoints were PFS and incidence of transfusions or Hb less than or equal to 8.0 g/dL from week 5 to end of the efficacy treatment period. RESULTS: The primary analysis set included 2516 patients: 1680 were randomized to darbepoetin alfa; 836 to placebo. The study was stopped early per independent Data Monitoring Committee recommendation after the primary endpoint was met with no new safety concerns. Darbepoetin alfa was noninferior to placebo for OS (stratified HR = 0.92; 95% confidence interval [CI]: 0.83‒1.01) and PFS (stratified HR = 0.95; 95% CI: 0.87‒1.04). Darbepoetin alfa was superior to placebo for transfusion or Hb less than or equal to 8.0 g/dL from week 5 to end of the efficacy treatment period (stratified odds ratio = 0.70; 95% CI: 0.57‒0.86; p < 0.001). Objective tumor response was similar between the groups (darbepoetin alfa, 36.4%; placebo, 32.6%). Incidence of serious adverse events was 31.1% in both groups. No unexpected adverse events were observed. CONCLUSIONS: Darbepoetin alfa dosed to a 12.0-g/dL Hb ceiling was noninferior to placebo for OS and PFS and significantly reduced odds of transfusion or Hb less than or equal to 8.0 g/dL in anemic patients with NSCLC receiving myelosuppressive chemotherapy.

INTRODUCTION: In an earlier report of the ASCEND-8 study (open-label, phase I, three-arm study, treatment-naive patients and pre-treated patients with advanced/metastatic NSCLC), it was shown that ceritinib 450 mg with food had comparable exposure and better gastrointestinal tolerability than 750-mg fasted. METHODS: Here, we report efficacy and updated safety data from primary efficacy analysis of the ASCEND-8 study. Key secondary endpoints were overall response rate and duration of response, assessed by blinded independent review committee (BIRC) using Response Evaluation Criteria in Solid Tumors 1.1. RESULTS: In total, 306 patients were randomized to ceritinib 450-mg fed (n = 108) or 600-mg fed (n = 87) or 750-mg fasted (n = 111), of which 304 patients were included in safety analysis and 198 treatment-naive patients (ALK receptor tyrosine kinase [ALK]-positive by immunohistochemistry) were included in the efficacy analysis (450-mg fed [n = 73], 600-mg fed [n = 51], and 750-mg fasted [n = 74]). The BIRC-assessed overall response rate was 78.1% (95% confidence interval [CI]: 66.9-86.9), 72.5% (95% CI: 58.3-84.1), and 75.7% (95% CI: 64.3-84.9), respectively; and the median duration of response (months) by BIRC was not estimable (NE) (95% CI: 11.2-NE), 20.7 (95% CI: 15.8-NE), and 15.4 (95% CI: 8.3-NE), respectively. Based on the safety analysis (n = 304), the 450-mg fed arm showed the highest median relative dose intensity (100% versus 78.5% versus 83.7%), lowest proportion of patients with dose reductions (24.1% versus 65.1% versus 60.9%), and lowest proportion of patients with gastrointestinal toxicities (75.9% versus 82.6% versus 91.8%). CONCLUSION: Ceritinib at a dose of 450 mg with food compared to 750-mg fasted showed consistent efficacy and less gastrointestinal toxicity.

BACKGROUND: Genome-wide association studies are widely used to map genomic regions contributing to lung cancer (LC) susceptibility, but they typically do not identify the precise disease-causing genes/variants. To unveil the inherited genetic variants that cause LC, we performed focused exome-sequencing analyses on genes located in 121 genome-wide association study-identified loci previously implicated in the risk of LC, chronic obstructive pulmonary disease, pulmonary function level, and smoking behavior. METHODS: Germline DNA from 260 case patients with LC and 318 controls were sequenced by utilizing VCRome 2.1 exome capture. Filtering was based on enrichment of rare and potential deleterious variants in cases (risk alleles) or controls (protective alleles). Allelic association analyses of single-variant and gene-based burden tests of multiple variants were performed. Promising candidates were tested in two independent validation studies with a total of 1773 case patients and 1123 controls. RESULTS: We identified 48 rare variants with deleterious effects in the discovery analysis and validated 12 of the 43 candidates that were covered in the validation platforms. The top validated candidates included one well-established truncating variant, namely, BRCA2, DNA repair associated gene (BRCA2) K3326X (OR = 2.36, 95% confidence interval [CI]: 1.38-3.99), and three newly identified variations, namely, lymphotoxin beta gene (LTB) p.Leu87Phe (OR = 7.52, 95% CI: 1.01-16.56), prolyl 3-hydroxylase 2 gene (P3H2) p.Gln185His (OR = 5.39, 95% CI: 0.75-15.43), and dishevelled associated activator of morphogenesis 2 gene (DAAM2) p.Asp762Gly (OR = 0.25, 95% CI: 0.10-0.79). Burden tests revealed strong associations between zinc finger protein 93 gene (ZNF93), DAAM2, bromodomain containing 9 gene (BRD9), and the gene LTB and LC susceptibility. CONCLUSION: Our results extend the catalogue of regions associated with LC and highlight the importance of germline rare coding variants in LC susceptibility.

INTRODUCTION: Lung cancer is the leading cause of cancer mortality worldwide; therefore, understanding the biological or clinical role of tumor-associated antigens and autoantibodies is of eminent interest for designing antitumor immunotherapeutic strategies. METHODS: Here we prospectively analyzed the serum frequencies of New York esophageal squamous cell carcinoma 1 (NY-ESO-1), human epidermal growth factor 2/neu, and melanoma-associated antigen A4 (MAGE-A4) antibodies and expression of the corresponding antigens in tumors of 121 patients with NSCLC undergoing an operation without prior neoadjuvant chemotherapy and compared them with those in 57 control age-matched patients with no history of a malignant disease. RESULTS: We found that only antibodies specific for NY-ESO-1 (19.8% [n = 24 of 121]) were significantly increased in the group of patients with NSCLC compared with in the controls. NY-ESO-1 seropositivity was significantly positively associated with an active smoking history in patients with NSCLC but not in smokers from the control group. In tumors, the frequency of NY-ESO-1 mRNA expression was 6.3% (in four of 64 patients), the frequency of human epidermal growth factor 2/neu (HER 2/neu) expression was 11.9% (five of 42), and the frequency of MAGE-A4 expression was 35.1% (20 of 57). MAGE-A4 expression in tumors correlated with smoking status and male sex in patients with NSCLC. Patients with squamous cell carcinoma displayed higher expression of NY-ESO-1 and MAGE-A4 in tumors than did patients with adenocarcinoma. On the other hand, 94.7% of nonsmoking patients in our study had adenocarcinoma (of whom 73.7% were women). CONCLUSION: These results confirm the reported high immunogenicity of NY-ESO-1 and suggest that a smoking-induced chronic inflammatory state might potentiate the development of NY-ESO-1-specific immune responses. Moreover, smoking might contribute to the expression of other cancer/testis antigens such as MAGE-A4 at early stages of NSCLC development.

The ImplementatioN of perSonalized medicine In NSCLC in Central Europe: EGFR testing, Histopathology, and clinical feaTures (INSIGHT) observational study assessed both implementation of epidermal growth factor receptor (EGFR) mutation testing and treatment of patients with advanced EGFR mutation-positive non-small-cell lung cancer (NSCLC) in a real-world setting in Central Europe. A total of 1785 patients from 14 cancer centers of six Central European countries were enrolled. EGFR mutations were detected in tumors of 13.8% of the patients. More than 70% of patients with advanced EGFR mutation-positive NSCLC received EGFR tyrosine kinase inhibitors as first-line therapy. The INSIGHT study demonstrated the establishment of EGFR mutation testing, a mutation rate consistent with other Caucasian patients populations, and adherence to current guidelines regarding treatment of patients with EGFR mutation-positive tumors in Central Europe.

INTRODUCTION: Thymic carcinoma is a rare and aggressive thymic neoplasm. The European Society of Thoracic Surgeons developed a retrospective database collecting patients undergoing resection for thymic tumors from 1990 to 2010. METHODS: Of 2265 patients with thymic tumors, there were 229 thymic carcinomas. Clinicopathological characteristics were analyzed including age, associated paraneoplastic diseases, stage (Masaoka-Koga), World Health Organization histologic subtypes, type of resection (total/subtotal/biopsy/no resection), tumor size, pre/postoperative treatments, and recurrence. Outcome measures included overall survival (OS), freedom from recurrence, and cumulative incidence of recurrence. RESULTS: A complete resection was achieved in 140 patients (69%). Recurrence occurred in 54 patients (28%). Five- and 10-year OS rates were 0.61 and 0.37. Five- and 10-year freedom from recurrence rates were 0.60 and 0.43. Cumulative incidence of recurrence was 0.21 (3 yr), 0.27 (5 yr), and 0.32 (10 yr). Survival was better after surgical resection versus biopsy/no resection (p < 0.001), after complete resection versus subtotal resection (p < 0.001), and when using Masaoka-Koga system (stages I-II versus III versus IV) (p < 0.001). The use of multidisciplinary treatments resulted in a survival advantage which was significant in the surgery + radiotherapy group (p = 0.02). Incomplete resection (p < 0.0001) and advanced stage (Masaoka-Koga III-IV) (p = 0.02) had a negative impact on OS at multivariable analysis. Administration of adjuvant radiotherapy was beneficial in increasing OS (p = 0.02). CONCLUSIONS: The results of our study indicate that patients with thymic carcinoma should undertake surgical resection whenever possible; a complete resection and early Masaoka-Koga stage are independent predictors of improved survival; our results also suggest that postoperative radiotherapy is beneficial in improving survival.

INTRODUCTION: This randomized phase II study investigated the efficacy and safety of a new taxane, larotaxel (XRP9881), in combination with either cisplatin or gemcitabine in the first-line treatment of patients with nonirradiable stage IIIB or stage IV non-small cell lung cancer to select the combination having the most promising antitumor activity. METHODS: Patients received either larotaxel (50 mg/m) as a 1-hour infusion, followed by a 1-hour infusion of cisplatin (75 mg/m), every 3 weeks (arm A), or gemcitabine (800 mg/m) as a 30 minute infusion, on days 1 and 8, and larotaxel (60 mg/m) as a 1-hour infusion, on day 8 (following gemcitabine), every 3 weeks (arm B). The primary end point was the objective response rate (per-protocol population). RESULTS: Thirty-two patients were randomized to arm A and 30 to arm B. The response rate was higher in arm A compared with arm B in both the per-protocol (26.7% versus 18.2%) and intention-to-treat (28.1% versus 13.3%) populations. In the intention-to-treat population, median progression-free survival for arm A versus arm B was 4.7 versus 3.3 months and median overall survival was 8.6 versus 7.3 months, respectively. Fifty percent of patients in arm A and 66.7% in arm B experienced at least one National Cancer Institute common toxicity criteria grade 3/4 adverse event and grade 3/4 neutropenia was observed in 46.9% and 41.4% of patients, respectively. CONCLUSIONS: Both larotaxel combinations were effective and manageable, however all measured efficacy parameters (response rate, progression free survival, and survival) seemed to favor the combination with cisplatin
