    ABSTRACT: PURPOSETo compare single-agent pemetrexed (P) versus the combination of carboplatin and pemetrexed (CP) in first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC) with an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 2. PATIENTS AND METHODS In a multicenter phase III randomized trial, patients with advanced NSCLC, ECOG PS of 2, any histology at first and later amended to nonsquamous only, no prior chemotherapy, and adequate organ function were randomly assigned to P alone (500 mg/m(2)) or CP (area under the curve of 5 and 500 mg/m(2), respectively) administered every 3 weeks for a total of four cycles. The primary end point was overall survival (OS).ResultsA total of 205 eligible patients were enrolled from eight centers in Brazil and one in the United States from April 2008 to July 2011. The response rates were 10.3% for P and 23.8% for CP (P = .032). In the intent-to-treat population, the median PFS was 2.8 months for P and 5.8 months for CP (hazard ratio [HR], 0.46; 95% CI, 0.35 to 0.63; P < .001), and the median OS was 5.3 months for P and 9.3 months for CP (HR, 0.62; 95% CI, 0.46 to 0.83; P = .001). One-year survival rates were 21.9% and 40.1%, respectively. Similar results were seen when patients with squamous disease were excluded from the analysis. Anemia (grade 3, 3.9%; grade 4, 11.7%) and neutropenia (grade 3, 1%; grade 4, 6.8%) were more frequent with CP. There were four treatment-related deaths in the CP arm. CONCLUSION Combination chemotherapy with CP significantly improves survival in patients with advanced NSCLC and ECOG PS of 2.

    ABSTRACT: Background Effective maintenance therapies after chemoradiotherapy for lung cancer are lacking. Our aim was to investigate whether the MUC1 antigen-specific cancer immunotherapy tecemotide improves survival in patients with stage III unresectable non-small-cell lung cancer when given as maintenance therapy after chemoradiation. Methods The phase 3 START trial was an international, randomised, double-blind trial that recruited patients with unresectable stage III non-small-cell lung cancer who had completed chemoradiotherapy within the 4–12 week window before randomisation and received confirmation of stable disease or objective response. Patients were stratified by stage (IIIA vs IIIB), response to chemoradiotherapy (stable disease vs objective response), delivery of chemoradiotherapy (concurrent vs sequential), and region using block randomisation, and were randomly assigned (2:1, double-blind) by a central interactive voice randomisation system to either tecemotide or placebo. Injections of tecemotide (806 μg lipopeptide) or placebo were given every week for 8 weeks, and then every 6 weeks until disease progression or withdrawal. Cyclophosphamide 300 mg/m2 (before tecemotide) or saline (before placebo) was given once before the first study drug administration. The primary endpoint was overall survival in a modified intention-to-treat population. This study is registered with, number NCT00409188. Findings From Feb 22, 2007, to Nov 15, 2011, 1513 patients were randomly assigned (1006 to tecemotide and 507 to placebo). 274 patients were excluded from the primary analysis population as a result of a clinical hold, resulting in analysis of 829 patients in the tecemotide group and 410 in the placebo group in the modified intention-to-treat population. Median overall survival was 25·6 months (95% CI 22·5–29·2) with tecemotide versus 22·3 months (19·6–25·5) with placebo (adjusted HR 0·88, 0·75–1·03; p=0·123). In the patients who received previous concurrent chemoradiotherapy, median overall survival for the 538 (65%) of 829 patients assigned to tecemotide was 30·8 months (95% CI 25·6–36·8) compared with 20·6 months (17·4–23·9) for the 268 (65%) of 410 patients assigned to placebo (adjusted HR 0·78, 0·64–0·95; p=0·016). In patients who received previous sequential chemoradiotherapy, overall survival did not differ between the 291 (35%) patients in the tecemotide group and the 142 (35%) patients in the placebo group (19·4 months [95% CI 17·6–23·1] vs 24·6 months [18·8–33·0], respectively; adjusted HR 1·12, 0·87–1·44; p=0·38). Grade 3–4 adverse events seen with a greater than 2% frequency with tecemotide were dyspnoea (49 [5%] of 1024 patients in the tecemotide group vs 21 [4%] of 477 patients in the placebo group), metastases to central nervous system (29 [3%] vs 6 [1%]), and pneumonia (23 [2%] vs 12 [3%]). Serious adverse events with a greater than 2% frequency with tecemotide were pneumonia (30 [3%] in the tecemotide group vs 14 [3%] in the placebo group), dyspnoea (29 [3%] vs 13 [3%]), and metastases to central nervous system (32 [3%] vs 9 [2%]). Serious immune-related adverse events did not differ between groups. Interpretation We found no significant difference in overall survival with the administration of tecemotide after chemoradiotherapy compared with placebo for all patients with unresectable stage III non-small-cell lung cancer. However, tecemotide might have a role for patients who initially receive concurrent chemoradiotherapy, and further study in this population is warranted. Funding Merck KGaA (Darmstadt, Germany).

    ABSTRACT: INTRODUCTION:: Denosumab, a fully human anti-RANKL monoclonal antibody, reduces the incidence of skeletal-related events in patients with bone metastases from solid tumors. We present survival data for the subset of patients with lung cancer, participating in the phase 3 trial of denosumab versus zoledronic acid (ZA) in the treatment of bone metastases from solid tumors (except breast or prostate) or multiple myeloma. METHODS:: Patients were randomized 1:1 to receive monthly subcutaneous denosumab 120 mg or intravenous ZA 4 mg. An exploratory analysis, using Kaplan-Meier estimates and proportional hazards models, was performed for overall survival among patients with non-small-cell lung cancer (NSCLC) and SCLC. RESULTS:: Denosumab was associated with improved median overall survival versus ZA in 811 patients with any lung cancer (8.9 versus 7.7 months; hazard ratio [HR] 0.80) and in 702 patients with NSCLC (9.5 versus 8.0 months; HR 0.78) (p = 0.01, each comparison). Further analysis of NSCLC by histological type showed a median survival of 8.6 months for denosumab versus 6.4 months for ZA in patients with squamous cell carcinoma (HR 0.68; p = 0.035). Incidence of overall adverse events was balanced between treatment groups; serious adverse events occurred in 66.0% of denosumab-treated patients and 72.9% of ZA-treated patients. Cumulative incidence of osteonecrosis of the jaw was similar between groups (0.7% denosumab versus 0.8% ZA). Hypocalcemia rates were 8.6% with denosumab and 3.8% with ZA. CONCLUSION:: In this exploratory analysis, denosumab was associated with improved overall survival compared with ZA, in patients with metastatic lung cancer.

    ABSTRACT: BACKGROUND: No targeted therapies are available for KRAS-mutant non-small-cell lung cancer (NSCLC). Selumetinib is an inhibitor of MEK1/MEK2, downstream of KRAS, with preclinical evidence of synergistic activity with docetaxel in KRAS-mutant cancers. We did a prospective, randomised, phase 2 trial to assess selumetinib plus docetaxel in previously treated patients with advanced KRAS-mutant NSCLC. METHODS: Eligible patients were older than 18 years of age; had histologically or cytologically confirmed stage IIIB-IV KRAS-mutant NSCLC; had failed first-line therapy for advanced NSCLC; had WHO performance status of 0-1; had not received previous therapy with either a MEK inhibitor or docetaxel; and had adequate bone marrow, renal, and liver function. Patients were randomly assigned (in a 1:1 ratio) to either oral selumetinib (75 mg twice daily in a 21 day cycle) or placebo; all patients received intravenous docetaxel (75 mg/m(2) on day 1 of a 21 day cycle). Randomisation was done with an interactive voice response system and investigators, patients, data analysts, and the trial sponsor were masked to treatment assignment. The primary endpoint was overall survival, analysed for all patients with confirmed KRAS mutations. This study is registered with, number NCT00890825. FINDINGS: Between April 20, 2009, and June 30, 2010, we randomly assigned 44 patients to receive selumetinib and docetaxel (selumetinib group) and 43 to receive placebo and docetaxel (placebo group). Of these, one patient in the selumetinib group and three in the placebo group were excluded from efficacy analyses because their tumours were not confirmed to be KRAS-mutation positive. Median overall survival was 9·4 months (6·8-13·6) in the selumetinib group and 5·2 months (95% CI 3·8-non-calculable) in the placebo group (hazard ratio [HR] for death 0·80, 80% CI 0·56-1·14; one-sided p=0·21). Median progression-free survival was 5·3 months (4·6-6·4) in the selumetinib group and 2·1 months (95% CI 1·4-3·7) in the placebo group (HR for progression 0·58, 80% CI 0·42-0·79; one-sided p=0·014). 16 (37%) patients in the selumetinib group and none in the placebo group had an objective response (p<0·0001). Adverse events of grade 3 or higher occurred in 36 (82%) patients in the selumetinib group and 28 (67%) patients in the placebo group. The most common grade 3-4 adverse events were neutropenia (29 [67%] of 43 patients in the selumetinib group vs 23 [55%] of 42 patients in the placebo group), febrile neutropenia (eight [18%] of 44 patients in the selumetinib group vs none in the placebo group), dyspnoea (one [2%] of 44 patients in the selumetinib group vs five [12%] of 42 in the placebo group), and asthenia (four [9%] of 44 patients in the selumetinib group vs none in the placebo group). INTERPRETATION: Selumetinib plus docetaxel has promising efficacy, albeit with a higher number of adverse events than with docetaxel alone, in previously treated advanced KRAS-mutant NSCLC. These findings warrant further clinical investigation of selumetinib plus docetaxel in KRAS-mutant NSCLC. FUNDING: AstraZeneca.

    ABSTRACT: Background: Linifanib is a potent and selective inhibitor of VEGF and PDGF receptors with modest single-agent activity in NSCLC. We evaluated the combination of linifanib with carboplatin (C) and paclitaxel (P) for first-line therapy of advanced non-squamous NSCLC. Methods: Patients (pts) with stage IIIB/IV, non-squamous NSCLC, stratified by ECOG PS and gender, were randomized to receive up to six 3-wk cycles of C (AUC 6 mg/ml/min) and P (200 mg/m2) with daily placebo (Arm A), linifanib 7.5 mg (Arm B), or linifanib 12.5 mg (Arm C). The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), 12 m survival rate, and objective response rate (ORR). Safety was assessed by NCI-CTCAE v3.0. Results: 138 pts were randomized at 37 sites in 6 countries. Baseline characteristics were: median age, 61 y; men, 57%; smoker, 84%. Efficacy results are shown in the table. Thrombocytopenia was the only Grade 3/4 AE significantly higher on linifanib (Arm B: 16.7%; Arm C: 29.8%) vs. placebo (2.1%). Other adverse events (AEs) related to the dose of linifanib were diarrhea, thrombocytopenia, hypertension, weight loss, palmar-plantar erythrodysaesthesia syndrome, and hypothyroidism. Analysis of samples for predictive biomarkers including serum VEGF and placental growth factor are underway. Conclusions: The addition of linifanib to chemotherapy was tolerable at the doses tested and resulted in a significant improvement in PFS, with a modest survival improvement for Arm C in first-line therapy of advanced non-squamous NSCLC.

    ABSTRACT: Pralatrexate, a folate analogue targeting dihydrofolate reductase, has antitumor activity in non-small-cell lung cancer (NSCLC). This randomized phase 2b trial was designed to further evaluate pralatrexate activity in NSCLC by estimating overall survival (OS) relative to erlotinib in patients with relapsed/refractory disease. In 43 centers across 6 countries, patients were randomized 1:1 to receive intravenous pralatrexate 190 mg/m on days 1 and 15 of a 28-day cycle, or oral erlotinib 150 mg/day. The primary objective was to estimate OS in all patients and prespecified subgroups using relative comparisons of hazard ratios (HRs). Secondary endpoints included progression-free survival, response rate, and safety. Key eligibility criteria included: (1) ≥1 prior platinum-based therapy, (2) Eastern Cooperative Oncology Group performance status of 0 to 1, and 3) a smoking history of 100 cigarettes or more. A total of 201 patients were randomized. A trend toward improvement in OS favoring pralatrexate was observed with an HR of 0.84 (95% confidence interval: 0.61-1.14) in the intent-to-treat population. This favorable survival result was seen in most prespecified subgroups for pralatrexate. The largest reduction in the risk of death was observed in patients with nonsquamous cell carcinoma (n = 107; HR = 0.65; 95% confidence interval: 0.42-1.0). The most common grade 3 to 4 adverse event in the pralatrexate arm was mucositis (23%). Discontinuation of pralatrexate for any grade of mucositis was 21%. Pralatrexate demonstrated a trend toward improved survival relative to erlotinib in patients with advanced NSCLC. Future studies should include a mucositis management plan to improve tolerability and maximize treatment benefit.

    ABSTRACT: Platinum-based doublet chemotherapy is considered the standard of care for advanced non-small cell lung cancer (NSCLC). However, prognosis after recurrent or progressive disease following first-line chemotherapy is usually poor. Maintenance chemotherapy, second line treatment and even third line chemotherapy are available for patients with advanced NSCLC. Unfortunately, few patients are candidates for chemotherapy beyond first line. The present study evaluated characteristics of patients with NSCLC and outcomes of the treatment of their metastatic disease, with emphasis on second and third-line chemotherapy. This was a retrospective observational study of 2,673 patients with metastatic, stage IV, non-small cell lung cancer admitted for treatment in two São Paulo institutions. First-line chemotherapy was defined as the first chemotherapeutic approach administered to the patient. Second and third-line chemotherapy were defined as the systemic treatment administered after discontinuing first-line chemotherapy, either for intolerance or for progressive or recurrent disease. Most patients (57.9%) received first-line chemotherapy, and approximately 23.4% received second-line and 8% third-line regimens. Only 2.5% received fourth-line chemotherapy. Median overall survival (OS) was 8 months (95% CI: 8-9 months). At univariate analyses, gender (p < 0.05), histology, first-line chemotherapy, objective response to first-line chemotherapy and second-line chemotherapy (p < 0.01) were prognostic factors related to overall survival. At multivariate analysis, only performance status (p = 0.04), receiving any second-line chemotherapy (p < 0.01) and response to first-line chemotherapy (p < 0.01) were independent predictors of overall survival. Second-line chemotherapy is a therapeutic strategy that should be considered for a selected group of patients. Performance status and response to first-line chemotherapy could be determinant characteristics to select patients who might be treated beyond first-line chemotherapy.

    ABSTRACT: 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.

    ABSTRACT: Several studies have shown the efficacy, tolerability, and ease of administration of pemetrexed-an antifolate antineoplastic agent-in patients with advanced non-small-cell lung cancer. We assessed pemetrexed as maintenance therapy in patients with this disease. This randomised double-blind study was undertaken in 83 centres in 20 countries. 663 patients with stage IIIB or IV disease who had not progressed on four cycles of platinum-based chemotherapy were randomly assigned (2:1 ratio) to receive pemetrexed (500 mg/m(2), day 1) plus best supportive care (n=441) or placebo plus best supportive care (n=222) in 21-day cycles until disease progression. Treatment was randomised with the Simon and Pocock minimisation method. Patients and investigators were masked to treatment. All patients received vitamin B(12), folic acid, and dexamethasone. The primary endpoint of progression-free survival and the secondary endpoint of overall survival were analysed by intention to treat. This study is registered with, number NCT00102804. All randomly assigned participants were analysed. Pemetrexed significantly improved progression-free survival (4.3 months [95% CI 4.1-4.7] vs 2.6 months [1.7-2.8]; hazard ratio [HR] 0.50, 95% CI 0.42-0.61, p<0.0001) and overall survival (13.4 months [11.9-15.9] vs 10.6 months [8.7-12.0]; HR 0.79, 0.65-0.95, p=0.012) compared with placebo. Treatment discontinuations due to drug-related toxic effects were higher in the pemetrexed group than in the placebo group (21 [5%] vs three [1%]). Drug-related grade three or higher toxic effects were higher with pemetrexed than with placebo (70 [16%] vs nine [4%]; p<0.0001), specifically fatigue (22 [5%] vs one [1%], p=0.001) and neutropenia (13 [3%] vs 0, p=0.006). No pemetrexed-related deaths occurred. Relatively fewer patients in the pemetrexed group than in the placebo group received systemic post-discontinuation therapy (227 [51%] vs 149 [67%]; p=0.0001). Maintenance therapy with pemetrexed is well tolerated and offers improved progression-free and overall survival compared with placebo in patients with advanced non-small-cell lung cancer. Eli Lilly.

    ABSTRACT: This study evaluated whether the combination of the synthetic rexinoid bexarotene with first-line cisplatin/vinorelbine therapy provides additional survival benefit in patients with advanced non-small-cell lung cancer (NSCLC). Patients with stage IIIB with pleural effusion or stage IV NSCLC and Eastern Cooperative Oncology Group performance status 0 to 1 were randomly assigned to open-label bexarotene 400 mg/m(2)/d with cisplatin/vinorelbine or to cisplatin/vinorelbine alone. Antilipid agents were initiated on or before day 1 in the bexarotene arm. Primary efficacy end point was overall survival. Primary, secondary and supportive efficacy analyses were conducted. A total of 623 patients (312 control, 311 bexarotene) were enrolled. Overall, no significant difference in survival occurred between the two treatment groups. However, an unplanned retrospective analysis showed that a subpopulation of bexarotene patients (n = 98 of 306) who experienced National Cancer Institute grade 3/4 hypertriglyceridemia had longer median survival compared with control patients (12.3 v 9.9 months; log-rank P = .08). Within that subgroup, those who benefited the most included males, smokers, those with stage IV disease, and those with a 6-month prior weight loss of 5% or more. Incidence, type and severity of grade 3/4 adverse events were comparable between arms, except for leukopenia (higher in chemotherapy arm) and hyperlipemia, hypothyroidism, dyspnea, and headache (higher in chemotherapy/bexarotene arm). The addition of bexarotene to first-line chemotherapy did not increase survival in patients with advanced NSCLC. However, a subgroup (32%) of bexarotene-treated patients developing high-grade hypertriglyceridemia appeared to have better survival (12.3 months) than controls; thus triglyceride response may be a biomarker of survival benefit with bexarotene.

    ABSTRACT: Patients with advanced non-small cell lung cancer (NSCLC) require care that emphasizes symptom palliation in addition to extending survival. The low response rates and minimal survival gains observed in second-line studies underscore the need to assess treatment efficacy with symptomatic end points. To characterize the relationship between patient-reported health-related quality of life outcomes and efficacy end points (tumor response, overall survival [OS], progression-free survival [PFS]), retrospective analyses were performed on Lung Cancer Symptom Scale (LCSS) data (n = 488) from the phase III study of pemetrexed (500 mg/m2 once every 3 weeks) versus docetaxel (75 mg/m2 once every 3 weeks) in advanced NSCLC. The LCSS data consisted of patient ratings of six symptoms and three summary items using 100-mm visual analogue scales. The mean maximum improvement for each item was categorized according to best tumor response, with statistical analyses based on a two-factor interaction model (with treatment arm and response group as fixed factors). Additional analyses pooled data between treatment arms and examined correlation (nonparametric and Pearson's) of time to first worsening of symptoms (TWS) with PFS and OS. All LCSS items, except hemoptysis, showed mean maximum improvement over baseline for responders and patients with stable disease (p < 0.01), with greater improvement associated with response. Median TWS for each LCSS item ranged between 2.3 months (fatigue) and 7.0 months (cough), with correlation between TWS and PFS and OS (all p values </=0.017). For most NSCLC patients, second-line chemotherapy provides symptomatic improvement that is linked to standard efficacy outcomes. Health-related quality of life data provides complementary efficacy information that can guide routine clinical practice.

    ABSTRACT: The phase III Iressa Survival Evaluation in Lung Cancer (ISEL) trial compared gefitinib with placebo in 1,692 patients with refractory advanced non-small-cell lung cancer. We analyzed ISEL tumor biopsy samples to examine relationships between biomarkers and clinical outcome after gefitinib treatment in a placebo-controlled setting. Biomarkers included epidermal growth factor receptor (EGFR) gene copy number by fluorescence in situ hybridization (n = 370); EGFR (n = 379) and phosphorylated Akt (p-Akt) protein expression (n = 382) by immunohistochemistry; and mutations in EGFR (n = 215), KRAS (n = 152), and BRAF (n = 118). High EGFR gene copy number was a predictor of a gefitinib-related effect on survival (hazard ratio [HR], 0.61 for high copy number and HR, 1.16 for low copy number; comparison of high v low copy number HR, P = .045). EGFR protein expression was also related to clinical outcome (HR for positive, 0.77; HR for negative, 1.57; comparison of high v low protein expression HR, P = .049). Patients with EGFR mutations had higher response rates than patients without EGFR mutations (37.5% v 2.6%); there were insufficient data for survival analysis. No relationship was observed between p-Akt protein expression and survival outcome, and the limited amount of data collected for KRAS and BRAF mutations prevented any meaningful evaluation of clinical outcomes in relation to these mutations. EGFR gene copy number was a predictor of clinical benefit from gefitinib in ISEL. Additional studies are warranted to assess these biomarkers fully for the identification of patients most likely to benefit from gefitinib treatment.

    ABSTRACT: Whether adjuvant chemotherapy improves survival of patients with non-small-cell lung cancer (NSCLC) is not known. We aimed to compare the effect of adjuvant vinorelbine plus cisplatin versus observation on survival in patients with completely resected NSCLC. 840 patients with stage IB-IIIA NSCLC from 101 centres in 14 countries were randomly assigned to observation (n=433) or to 30 mg/m(2) vinorelbine plus 100 mg/m(2) cisplatin (n=407). Postoperative radiotherapy was not mandatory and was undertaken according to every centre's policy. The primary endpoint was overall survival. Analysis was by intention to treat. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN95053737. 367 patients in the chemotherapy group and 431 in the control group received their assigned treatment. 301 (36%) patients had stage IB disease, 203 (24%) had stage II disease, and 325 (39%) had stage IIIA disease. Tolerance to chemotherapy mainly included neutropenia in 335 (92%) patients and febrile neutropenia in 34 (9%); seven (2%) toxic deaths were also recorded. Compliance was greater with cisplatin than with vinorelbine (median dose intensity 89% [range 17-108] vs 59% [17-100]). After a median follow-up of 76 months (range 43-116), median survival was 65.7 months (95% CI 47.9-88.5) in the chemotherapy group and 43.7 (35.7-52.3) months in the observation group. Adjusted risk for death was significantly reduced in patients assigned chemotherapy compared with controls (hazard ratio 0.80 [95% CI 0.66-0.96]; p=0.017). Overall survival at 5 years with chemotherapy improved by 8.6%, which was maintained at 7 years (8.4%). Adjuvant vinorelbine plus cisplatin extends survival in patients with completely resected NSCLC, better defining indication of adjuvant chemotherapy.

    ABSTRACT: This placebo-controlled phase III study investigated the effect on survival of gefitinib as second-line or third-line treatment for patients with locally advanced or metastatic non-small-cell lung cancer. 1692 patients who were refractory to or intolerant of their latest chemotherapy regimen were randomly assigned in a ratio of two to one either gefitinib (250 mg/day) or placebo, plus best supportive care. The primary endpoint was survival in the overall population of patients and those with adenocarcinoma. The primary analysis of the population for survival was by intention to treat. This study has been submitted for registration with, number 1839IL/709. 1129 patients were assigned gefitinib and 563 placebo. At median follow-up of 7.2 months, median survival did not differ significantly between the groups in the overall population (5.6 months for gefitinib and 5.1 months for placebo; hazard ratio 0.89 [95% CI 0.77-1.02], p=0.087) or among the 812 patients with adenocarcinoma (6.3 months vs 5.4 months; 0.84 [0.68-1.03], p=0.089). Preplanned subgroup analyses showed significantly longer survival in the gefitinib group than the placebo group for never-smokers (n=375; 0.67 [0.49-0.92], p=0.012; median survival 8.9 vs 6.1 months) and patients of Asian origin (n=342; 0.66 [0.48-0.91], p=0.01; median survival 9.5 vs 5.5 months). Gefitinib was well tolerated, as in previous studies. Treatment with gefitinib was not associated with significant improvement in survival in either coprimary population. There was pronounced heterogeneity in survival outcomes between groups of patients, with some evidence of benefit among never-smokers and patients of Asian origin.

    ABSTRACT: We conducted a randomized, placebo-controlled, double-blind trial to determine whether the epidermal growth factor receptor inhibitor erlotinib prolongs survival in non-small-cell lung cancer after the failure of first-line or second-line chemotherapy. Patients with stage IIIB or IV non-small-cell lung cancer, with performance status from 0 to 3, were eligible if they had received one or two prior chemotherapy regimens. The patients were stratified according to center, performance status, response to prior chemotherapy, number of prior regimens, and prior platinum-based therapy and were randomly assigned in a 2:1 ratio to receive oral erlotinib, at a dose of 150 mg daily, or placebo. The median age of the 731 patients who underwent randomization was 61.4 years; 49 percent had received two prior chemotherapy regimens, and 93 percent had received platinum-based chemotherapy. The response rate was 8.9 percent in the erlotinib group and less than 1 percent in the placebo group (P<0.001); the median duration of the response was 7.9 months and 3.7 months, respectively. Progression-free survival was 2.2 months and 1.8 months, respectively (hazard ratio, 0.61, adjusted for stratification categories; P<0.001). Overall survival was 6.7 months and 4.7 months, respectively (hazard ratio, 0.70; P<0.001), in favor of erlotinib. Five percent of patients discontinued erlotinib because of toxic effects. Erlotinib can prolong survival in patients with non-small-cell lung cancer after first-line or second-line chemotherapy.
