RESUMEN
PURPOSE: To compare the efficacy and toxicity of pemetrexed versus docetaxel in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with chemotherapy. PATIENTS AND METHODS: Eligible patients had a performance status 0 to 2, previous treatment with one prior chemotherapy regimen for advanced NSCLC, and adequate organ function. Patients received pemetrexed 500 mg/m2 intravenously (IV) day 1 with vitamin B12, folic acid, and dexamethasone or docetaxel 75 mg/m2 IV day 1 with dexamethasone every 21 days. The primary end point was overall survival. RESULTS: Five hundred seventy-one patients were randomly assigned. Overall response rates were 9.1% and 8.8% (analysis of variance P = .105) for pemetrexed and docetaxel, respectively. Median progression-free survival was 2.9 months for each arm, and median survival time was 8.3 versus 7.9 months (P = not significant) for pemetrexed and docetaxel, respectively. The 1-year survival rate for each arm was 29.7%. Patients receiving docetaxel were more likely to have grade 3 or 4 neutropenia (40.2% v 5.3%; P < .001), febrile neutropenia (12.7% v 1.9%; P < .001), neutropenia with infections (3.3% v 0.0%; P = .004), hospitalizations for neutropenic fever (13.4% v 1.5%; P < .001), hospitalizations due to other drug related adverse events (10.5% v 6.4%; P = .092), use of granulocyte colony-stimulating factor support (19.2% v 2.6%, P < .001) and all grade alopecia (37.7% v 6.4%; P < .001) compared with patients receiving pemetrexed. CONCLUSION: Treatment with pemetrexed resulted in clinically equivalent efficacy outcomes, but with significantly fewer side effects compared with docetaxel in the second-line treatment of patients with advanced NSCLC and should be considered a standard treatment option for second-line NSCLC when available.
RESUMEN
PURPOSE: Linifanib, a potent, selective inhibitor of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptors, has single-agent activity in non-small-cell lung cancer (NSCLC). We evaluated linifanib with carboplatin and paclitaxel as first-line therapy of advanced nonsquamous NSCLC. PATIENTS AND METHODS: Patients with stage IIIB/IV nonsquamous NSCLC were randomly assigned to 3-week cycles of carboplatin (area under the curve 6) and paclitaxel (200 mg/m(2)) with daily placebo (arm A), linifanib 7.5 mg (arm B), or linifanib 12.5 mg (arm C). The primary end point was progression-free survival (PFS); secondary efficacy end points included overall survival (OS) and objective response rate. RESULTS: One hundred thirty-eight patients were randomly assigned (median age, 61 years; 57% men; 84% smokers). Median PFS times were 5.4 months (95% CI, 4.2 to 5.7 months) in arm A (n = 47), 8.3 months (95% CI, 4.2 to 10.8 months) in arm B (n = 44), and 7.3 months (95% CI, 4.6 to 10.8 months) in arm C (n = 47). Hazard ratios (HRs) for PFS were 0.51 for arm B versus A (P = .022) and 0.64 for arm C versus A (P = .118). Median OS times were 11.3, 11.4, and 13.0 months in arms A, B, and C, respectively. HRs for OS were 1.08 for arm B versus A (P = .779) and 0.88 for arm C versus A (P = .650). Both linifanib doses were associated with increased toxicity, including a higher incidence of adverse events known to be associated with VEGF/PDGF inhibition. Baseline plasma carcinoembryonic antigen/cytokeratin 19 fragments biomarker signature was associated with PFS improvement and a trend toward OS improvement with linifanib 12.5 mg. CONCLUSION: Addition of linifanib to chemotherapy significantly improved PFS (arm B), with a modest trend for survival benefit (arm C) and increased toxicity reflective of known VEGF/PDGF inhibitory effects.

BACKGROUND: Findings from the phase 3 First-Line ErbituX in lung cancer (FLEX) study showed that the addition of cetuximab to first-line chemotherapy significantly improved overall survival compared with chemotherapy alone (hazard ratio [HR] 0·871, 95% CI 0·762-0·996; p=0·044) in patients with advanced non-small-cell lung cancer (NSCLC). To define patients benefiting most from cetuximab, we studied the association of tumour EGFR expression level with clinical outcome in FLEX study patients. METHODS: We used prospectively collected tumour EGFR expression data to generate an immunohistochemistry score for FLEX study patients on a continuous scale of 0-300. We used response data to select an outcome-based discriminatory threshold immunohistochemistry score for EGFR expression of 200. Treatment outcome was analysed in patients with low (immunohistochemistry score <200) and high (≥200) tumour EGFR expression. The primary endpoint in the FLEX study was overall survival. We analysed patients from the FLEX intention-to-treat (ITT) population. The FLEX study is registered with ClinicalTrials.gov, number NCT00148798. FINDINGS: Tumour EGFR immunohistochemistry data were available for 1121 of 1125 (99·6%) patients from the FLEX study ITT population. High EGFR expression was scored for 345 (31%) evaluable patients and low for 776 (69%) patients. For patients in the high EGFR expression group, overall survival was longer in the chemotherapy plus cetuximab group than in the chemotherapy alone group (median 12·0 months [95% CI 10·2-15·2] vs 9·6 months [7·6-10·6]; HR 0·73, 0·58-0·93; p=0·011), with no meaningful increase in side-effects. We recorded no corresponding survival benefit for patients in the low EGFR expression group (median 9·8 months [8·9-12·2] vs 10·3 months [9·2-11·5]; HR 0·99, 0·84-1·16; p=0·88). A treatment interaction test assessing the difference in the HRs for overall survival between the EGFR expression groups suggested a predictive value for EGFR expression (p=0·044). INTERPRETATION: High EGFR expression is a tumour biomarker that can predict survival benefit from the addition of cetuximab to first-line chemotherapy in patients with advanced NSCLC. Assessment of EGFR expression could offer a personalised treatment approach in this setting. FUNDING: Merck KGaA.

BACKGROUND: Findings from the phase 3 FLEX study showed that the addition of cetuximab to cisplatin and vinorelbine significantly improved overall survival, compared with cisplatin and vinorelbine alone, in the first-line treatment of EGFR-expressing, advanced non-small-cell lung cancer (NSCLC). We investigated whether candidate biomarkers were predictive for the efficacy of chemotherapy plus cetuximab in this setting. METHODS: Genomic DNA extracted from formalin-fixed paraffin-embedded (FFPE) tumour tissue of patients enrolled in the FLEX study was screened for KRAS codon 12 and 13 and EGFR kinase domain mutations with PCR-based assays. In FFPE tissue sections, EGFR copy number was assessed by dual-colour fluorescence in-situ hybridisation and PTEN expression by immunohistochemistry. Treatment outcome was investigated according to biomarker status in all available samples from patients in the intention-to-treat population. The primary endpoint in the FLEX study was overall survival. The FLEX study, which is ongoing but not recruiting participants, is registered with ClinicalTrials.gov, number NCT00148798. FINDINGS: KRAS mutations were detected in 75 of 395 (19%) tumours and activating EGFR mutations in 64 of 436 (15%). EGFR copy number was scored as increased in 102 of 279 (37%) tumours and PTEN expression as negative in 107 of 303 (35%). Comparisons of treatment outcome between the two groups (chemotherapy plus cetuximab vs chemotherapy alone) according to biomarker status provided no indication that these biomarkers were of predictive value. Activating EGFR mutations were identified as indicators of good prognosis, with patients in both treatment groups whose tumours carried such mutations having improved survival compared with those whose tumours did not (chemotherapy plus cetuximab: median 17·5 months [95% CI 11·7-23·4] vs 8·5 months [7·1-10·8], hazard ratio [HR] 0·52 [0·32-0·84], p=0·0063; chemotherapy alone: 23·8 months [15·2-not reached] vs 10·0 months [8·7-11·0], HR 0·35 [0·21-0·59], p<0·0001). Expression of PTEN seemed to be a potential indicator of good prognosis, with patients whose tumours expressed PTEN having improved survival compared with those whose tumours did not, although this finding was not significant (chemotherapy plus cetuximab: median 11·4 months [8·6-13·6] vs 6·8 months [5·9-12·7], HR 0·80 [0·55-1·16], p=0·24; chemotherapy alone: 11·0 months [9·2-12·6] vs 9·3 months [7·6-11·9], HR 0·77 [0·54-1·10], p=0·16). INTERPRETATION: The efficacy of chemotherapy plus cetuximab in the first-line treatment of advanced NSCLC seems to be independent of each of the biomarkers assessed. FUNDING: Merck KGaA.

BACKGROUND: Use of cetuximab, a monoclonal antibody targeting the epidermal growth factor receptor (EGFR), has the potential to increase survival in patients with advanced non-small-cell lung cancer. We therefore compared chemotherapy plus cetuximab with chemotherapy alone in patients with advanced EGFR-positive non-small-cell lung cancer. METHODS: In a multinational, multicentre, open-label, phase III trial, chemotherapy-naive patients (>or=18 years) with advanced EGFR-expressing histologically or cytologically proven stage wet IIIB or stage IV non-small-cell lung cancer were randomly assigned in a 1:1 ratio to chemotherapy plus cetuximab or just chemotherapy. Chemotherapy was cisplatin 80 mg/m(2) intravenous infusion on day 1, and vinorelbine 25 mg/m(2) intravenous infusion on days 1 and 8 of every 3-week cycle) for up to six cycles. Cetuximab-at a starting dose of 400 mg/m(2) intravenous infusion over 2 h on day 1, and from day 8 onwards at 250 mg/m(2) over 1 h per week-was continued after the end of chemotherapy until disease progression or unacceptable toxicity had occurred. The primary endpoint was overall survival. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00148798. FINDINGS: Between October, 2004, and January, 2006, 1125 patients were randomly assigned to chemotherapy plus cetuximab (n=557) or chemotherapy alone (n=568). Patients given chemotherapy plus cetuximab survived longer than those in the chemotherapy-alone group (median 11.3 months vs 10.1 months; hazard ratio for death 0.871 [95% CI 0.762-0.996]; p=0.044). The main cetuximab-related adverse event was acne-like rash (57 [10%] of 548, grade 3). INTERPRETATION: Addition of cetuximab to platinum-based chemotherapy represents a new treatment option for patients with advanced non-small-cell lung cancer. FUNDING: Merck KGaA.

Previous studies have indicated that, in combination with cisplatin, fixed dose rate gemcitabine may be more efficacious than standard infusion gemcitabine. This open-label, randomised phase II study was aimed to compare the efficacy and safety of these regimens as treatment for advanced non-small cell lung cancer (NSCLC) in Latin American patients. Sixty-four patients were randomised to receive up to six cycles of treatment with cisplatin 75 mg/m(2) on Day 1 plus either gemcitabine 1000 mg/m(2) over 30 min on Days 1 and 8 of a 21-day cycle (standard arm, N=33) or gemcitabine 1000 mg/m(2) at a fixed dose rate of 10 mg/m(2)/min on Days 1 and 8 of a 21-day cycle (FDR arm, N=31). In the standard arm, 9 of 33 (27%) patients responded compared with 6 of 30 (20%) patients in the FDR arm (odds ratio: 0.67, 95% CI, 0.21-2.2; p=0.56). Median overall survival was 7.5 months in the standard arm and 9.9 months in the FDR arm. One-year survival rates were 35% and 37% in the standard arm and the FDR arm, respectively. Patients in the FDR arm experienced more grade 3/4 haematological toxicity than those in the standard arm (48% versus 21%). The results of this trial do not support FDR administration of gemcitabine in preference to the standard administration in Latin American patients with NSCLC.

BACKGROUND: Patients with advanced non-small cell lung cancer (NSCLC) do not have curative treatment options; therefore, treatments should prolong survival and improve quality of life (QoL). We compared the effect on QoL of two docetaxel-platinum regimens with vinorelbine-cisplatin. METHODS: QoL was assessed by the Lung Cancer Symptom Scale (LCSS) and the general EuroQol five-dimensional questionnaire (EQ-5D) in 926 chemotherapy-naïve patients with stages IIIB to IV NSCLC. Patients were randomly assigned to receive: docetaxel 75 mg/m2 plus cisplatin 75 mg/m2, every 3 weeks (DC); docetaxel 75 mg/m2 and carboplatin 6 mg/ml min, every 3 weeks (DCb); or vinorelbine 25 mg/m2/week plus cisplatin 100 mg/m2, every 4 weeks (VC). RESULTS: Overall, patients treated with either docetaxel-containing regimen had better QoL than VC-treated patients (LCSS global item "QoL today": P=0.064 for DC and P=0.016 for DCb versus VC; EQ-5D global item "health state today": P=0.016 for DC and P<0.001 for DCb versus VC). DC-treated patients experienced improved pain relief compared with VC (P=0.033), whereas pain relief with DCb and VC was similar. Patients treated with either docetaxel regimen had more favorable changes in performance status (P=0.065 for DC and P<0.001 for DCb versus VC) and mean weight loss (0.06 kg, gain of 0.08 kg, and 2.27 kg for DC, DCb, and VC, respectively; P<0.001 for both DC versus VC and DCb versus VC). CONCLUSION: The TAX 326 study shows that docetaxel-platinum regimens relieve symptoms and improve QoL in patients with advanced NSCLC. DCb and DC were superior to VC in all QoL outcomes assessed except for the difference between DC and VC in LCSS "QoL today", which was not significant.

PATIENTS AND METHODS: Eligible patients had a performance status 0 to 2, previous treatment with one prior chemotherapy regimen for advanced NSCLC, and adequate organ function. Patients received pemetrexed 500 mg/m(2) intravenously (i.v.) day 1 with vitamin B(12), folic acid, and dexamethasone or docetaxel 75 mg/m(2) i.v. day 1 with dexamethasone every 21 days. The primary end point was overall survival. RESULTS: Five hundred seventy-one patients were randomly assigned. Overall response rates were 9.1% and 8.8% (analysis of variance P =.105) for pemetrexed and docetaxel, respectively. Median progression-free survival was 2.9 months for each arm, and median survival time was 8.3 versus 7.9 months (P = not significant) for pemetrexed and docetaxel, respectively. The 1-year survival rate for each arm was 29.7%. Patients receiving docetaxel were more likely to have grade 3 or 4 neutropenia (40.2% v 5.3%; P <.001), febrile neutropenia (12.7% v 1.9%; P <.001), neutropenia with infections (3.3% v 0.0%; P =.004), hospitalizations for neutropenic fever (13.4% v 1.5%; P <.001), hospitalizations due to other drug related adverse events (10.5% v 6.4%; P =.092), use of granulocyte colony-stimulating factor support (19.2% v 2.6%, P <.001) and all grade alopecia (37.7% v 6.4%; P <.001) compared with patients receiving pemetrexed. CONCLUSION: Treatment with pemetrexed resulted in clinically equivalent efficacy outcomes, but with significantly fewer side effects compared with docetaxel in the second-line treatment of patients with advanced NSCLC and should be considered a standard treatment option for second-line NSCLC when available.

PURPOSE: To investigate whether docetaxel plus platinum regimens improve survival and affect quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC) compared with vinorelbine plus cisplatin as first-line chemotherapy. PATIENTS AND METHODS: Patients (n = 1,218) with stage IIIB to IV NSCLC were randomly assigned to receive docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks (DC); docetaxel 75 mg/m2 and carboplatin area under the curve of 6 mg/mL * min every 3 weeks (DCb); or vinorelbine 25 mg/m2/wk and cisplatin 100 mg/m2 every 4 weeks (VC). RESULTS: Patients treated with DC had a median survival of 11.3 v 10.1 months for VC-treated patients (P =.044; hazard ratio, 1.183 [97.2% confidence interval, 0.989 to 1.416]). The 2-year survival rate was 21% for DC-treated patients and 14% for VC-treated patients. Overall response rate was 31.6% for DC-treated patients v 24.5% for VC-treated patients (P =.029). Median survival (9.4 v 9.9 months [for VC]; P =.657; hazard ratio, 1.048 [97.2 confidence interval, 0.877 to 1.253]) and response (23.9%) with DCb were similar to those results for VC. Neutropenia, thrombocytopenia, infection, and febrile neutropenia were similar with all three regimens. Grade 3 to 4 anemia, nausea, and vomiting were more common (P <.01) with VC than with DC or DCb. Patients treated with either docetaxel regimen had consistently improved QoL compared with VC-treated patients, who experienced deterioration in QoL. CONCLUSION: DC resulted in a more favorable overall response and survival rate than VC. Both DC and DCb were better tolerated and provided patients with consistently improved QoL compared with VC. These findings demonstrate that a docetaxel plus platinum combination is an effective treatment option with a favorable therapeutic index for first-line treatment of advanced or metastatic NSCLC.
