TPS7109 Background: This is an ongoing phase III multicenter randomized trial comparing adjuvant pharmacogenomic-driven chemotherapy, based on thymidilate synthase (TS) and excision-repair cross-complementing -1 (ERCC1) gene expression versus standard adjuvant chemotherapy in completely resected stage II-IIIA non-small cell lung cancer (EudraCT #: 2008-001764-36). Methods: In all registered patients, before randomization, expression of ERCC1 and TS is assessed by qRT-PCR on paraffin-embedded tumor specimens in a central laboratory. Randomization is stratified by stage and smoking status. Trial was emended on Feb, 2011 with the 7th staging system. Primary end point is overall survival; secondary end points include recurrence-free survival, therapeutic compliance, toxicity profile and comparative evaluation of ERCC1 and TS mRNA versus protein. It is assumed that the 5-year survival in the control arm is 45% and the hazard reduction associated to the experimental treatment is 30%. With a power of 90% to detect the estimated effect with log-rank test, a significant level of 5% (2 tails), 336 events have to be observed; the expected total number of patients is 700. The final statistical analysis will group together all control arms and all tailored chemotherapies groups. Efficacy analysis will be done on an intent-to-treat basis. Cox proportional hazard model will be used for estimating hazard ratios after adjusting for relevant variables. Within 45 days post-surgery, patients in each genetic profile are randomized to receive either a standard chemotherapy selected by the investigator (cisplatin/vinorelbine, cisplatin/docetaxel or cisplatin/gemcitabine) or an experimental treatment (tailored arms) selected as follows: 1) high ERCC1 and high TS 4 cycles of single agent paclitaxel 2) high ERCC1 and low TS 4 cycles of single agent pemetrexed 3) low ERCC1 and high TS 4 cycles of cisplatin/gemcitabine 4) low ERCC1 and low TS) 4 cycles of cisplatin/pemetrexed. All chemotherapy regimens are administered for a total of 4 cycles on a 3-weekly basis. Currently, 312 patients have been randomized from 26 institutions mainly located in Italy and Germany (average enrolment: 13 patients/month).

1015 Background: Gemcitabine (G), either as a single agent or in combination with taxanes, has demonstrated efficacy in MBC in phase II and III studies. We conducted a phase III study to compare time to progression (TTP) of G plus docetaxel (T) versus (vs.) T alone. The secondary endpoints included overall survival (OS), overall response rate (ORR), and toxicity. Methods: Females with HER-2-negative locally advanced or MBC and a WHO performance status ≤ 2 were randomized to GT (G 1,000mg/m2 day 1 + 8; T 75mg/m2 day 1) or T (100mg/m2 day 1) every 21 days. Pts were previously untreated, had prior anthracycline-based (neo)adjuvant chemotherapy or had received a single prior anthracycline-bsed chemotherapy regimen for MBC. Time-to-event endpoints were estimated using the Kaplan-Meier method, and the log-rank test was applied for comparisons between regimens. The planned sample size was 254 evaluable pts with α I and β of 0.05 and 0.90, respectively. Results: A total of 336 pts were randomized (170 GT; 166 T), data from one centre are yet missing and the present evaluation is based on data from 306 pts (155 GT; 151 T). The pts had a median age of 58 years in both regimens; range 36–73 years and 30–74 years, respectively. The median TTP was 7.5 months for the GT regimen vs. 6.5 months for the T regimen. The GT arm demonstrated an ORR of 44% vs. 38% in the T arm with 4 and 3 % complete responses, respectively. The OS was 13.4 vs. 13.2 months in the GT and T arm, respectively. Hematologic toxicity was common, especially grade 3–4 neutropenia (GT = 69%; T = 61%); infection was reported in 22 and 20% of the pts, respectively (none of the pts received G-CSF). The most commonly reported non-hematologic toxicities of grade 3–4 included mucositis (GT = 2%; T = 5%), diarrhea (GT = 4%; T = 7 %), fatigue (GT = 6%; T = 11%), oedema (GT = 10%; T = 3%), and peripheral neuropathy (GT = 9%; T = 28%). Conclusions: Preliminary data of GT as first- or second-line chemotherapy demonstrates a TTP advantage among HER-2-negative pts with advanced breast cancer. Updated results and proper statistical analyses will be presented. No significant financial relationships to disclose.

320 Background: HFS and related skin toxicities are common side effects of tyrosine kinase inhibitors such as SU, a multitargeted inhibitor of VEGF and PDGF receptors plus other receptor tyrosine kinases. In a randomized phase III trial of treatment-naïve mRCC pts, SU showed superior progression-free survival (PFS) and objective response rate (ORR) over interferon-alfa, with a median PFS of 11 mo and median overall survival (OS) of 26.4 mo, establishing SU as a reference standard of care (Motzer et al, 2009). In this retrospective analysis, correlations between SU-associated HFS and efficacy endpoints were investigated in mRCC pts from 5 clinical trials in the first- and second-line treatment settings. Methods: Analyses included pooled data from 770 pts who received single-agent SU as 50 mg/d on a 4-week-on/2-week-off schedule (n=544; 71%) or 37.5 mg continuous once-daily dosing (n=226; 29%). Median PFS and OS were estimated by Kaplan–Meier methods and compared between pts with vs without HFS using a log-rank test. ORR was compared by Pearson's chi-square test. Tumor response was assessed by investigators and adverse events were recorded regularly. Multivariate and time-dependent covariate analyses were performed. Results: Of 770 pts, 179 (23%) developed any-grade HFS, compared with 591 (77%) who did not. Most instances of HFS (63%) initially occurred during the first 3 treatment cycles. Pts who developed HFS had significantly better ORR (55.6% vs. 32.7%), PFS (14.3 vs. 8.3 mo), and OS (38.3 vs. 18.9 mo) than pts who did not develop HFS (p<0.0001). In a multivariate analysis, SU-associated HFS remained a significant independent predictor of both PFS and OS (and of OS by time-dependent covariate analysis). Conclusions: In mRCC pts, SU-associated HFS was significantly and independently associated with improved clinical outcomes. Overall, pts who did not develop HFS still had substantial benefit from SU. However, the presence of HFS identified a subset of pts that manifested highly favorable efficacy results with SU. These findings suggest that development of HFS may serve as a predictive biomarker of SU efficacy, although prospective validation is warranted. [Table: see text]

6006 Background: We studied the association of human papillomavirus (HPV) and excision repair cross-complementation group 1 (ERCC1) tumor expression with clinical outcomes in patients (pts) with R/M SCCHN. Methods: Archival baseline specimens were obtained from pts on ECOG trials: E1395, phase III trial of cisplatin/paclitaxel (CP) vs. cisplatin/5-FU (CF), and E3301, phase II trial of docetaxel/irinotecan. HPV DNA was detected by in situ hybridization (ISH) with a wide spectrum HPV probe. Tumor p16 status was defined as positive if immunohistochemical staining for p16 was strong and present in >80% of tumor cells. ERCC1 expression was measured (HistoRx PM-2000) and data analyzed using AQUA algorithms, after tissue was stained with ERCC1 ab (1:5000 HPA0297731, Sigma), and a wide-spectrum cytokeratin ab (Dako Z0622) for tumor mask. A prior determined cut point for nuclear staining was utilized. Fisher's exact test and log-rank test were used to compare categorical variables and survival. Stratified logistic regression and Cox regression model were used to estimate odds ratio (OR) and hazard ratio (HR), respectively, adjusting for potential confounding factors. p-values were two-sided. Results: Tissue was evaluable from 65 tumors (T) for HPV, 66 for p16 (E1395 and E3301), and 43 for ERCC1 expression (E1395). 11 T were HPV+ (12 p16+), and 54 were HPV-/p16-. HPV+ tumors were similarly represented in all treatment groups (p=0.58). Objective response rates (RR): 67% for HPV+, 22% for HPV- (p=0.013); 60% p16+, 22% p16- (p=0.05). RR rates were calculated excluding cases with unevaluable/unknown responses. HR for OS was 2.66 (HPV, p=0.02) and 2.27 (p16, p=0.04), favoring HPV+/p16+ pts. 18 T were ERCC1 high (H) and 25 ERCC1 low (L). HR for OS (H vs. L) was 1.96 (p=.11) RR: CF, 58% (L), 29% (H); CP, 33% (L), 56% (H). A test of ERCC1 by treatment interaction (p=0.12) suggested the effect of ERCC1 may be different for taxane vs. non-taxane regimens. Conclusions: This is the first study to show that HPV+/p16+ status is associated with a significant improvement in RR and OS among pts treated for R/M SCCHN. ERCC1 L was associated with a trend towards a better OS.

e12105 Background: The best sequence of anthracyclines and taxanes in the neoadjuvant chemotherapy of HER2-negative breast cancer is still unknown. The aims of this study were to assess the impact of the sequence order in the pathological complete response (pCR) rate, and in the disease free survival (DFS) and overall survival (OS). Methods: We retrospectively reviewed 235 HER2-negative breast cancer women treated with neoadjuvant chemotherapy from 2003 to 2011 at our cancer center. The patients were pooled in two groups: anthracycline-based followed by taxanes (AC-T) and the reverse sequence (T-AC). The chi-square test was performed to verify the homogeneity between the groups and to compare pCR rate among the treatment groups. Cumulative survival probabilities were calculated using the Kaplan-Meier method. Differences between survivals were tested using the log-rank test. Results: The AC-T (n = 161) and T-AC (n = 74) groups were balanced for age, staging, receptor profile and histologic grade. The follow-up was at least five years for each patient. The median age was 50.1 years. Most patients (97%) had stage III tumors and 72 (30%) had triple negative disease. pCR rate was higher in triple negative compared with luminal cases (16.3 vs. 7.3%; p = 0.049). Treatment sequence did not influence the occurrence of pCR (10.5 vs. 8.5%; p = 0.8) or median survival times (DFS: 87.9 vs. 64.1, p = 0.85; OS: 91.1 vs. 71.6 months, p = 0.15), in the AC-T and T-AC groups, respectively. Conclusions: The sequence of neoadjuvant taxane-anthracycline-based chemotherapy regimen in daily practice did not show difference in the evaluated clinical outcomes. The retrospective design and the low number of patients may limit the power of the study to detect statistically significant differences. Phase III trials should be stimulated in this context.

Purpose To compare the efficacy of four cycles of paclitaxel–bleomycin, etoposide, and cisplatin (T-BEP) to four cycles of bleomycin, etoposide, and cisplatin (BEP) in previously untreated patients with intermediate-prognosis germ-cell cancer (GCC). Patients and Methods Patients were randomly assigned to receive either T-BEP or standard BEP. Patients assigned to the T-BEP group received paclitaxel 175 mg/m2 in a 3-hour infusion. Patients who were administered T-BEP received primary granulocyte colony-stimulating factor (G-CSF) prophylaxis. The study was designed as a randomized open-label phase II/III study. To show a 10% improvement in 3-year progression-free survival (PFS), the study aimed to recruit 498 patients but closed with 337 patients as a result of slow accrual. Results Accrual was from November 1998 to April 2009. A total of 169patients were administered BEP, and 168 patients were administered T-BEP. Thirteen patients in both arms were ineligible, mainly as a result of a good prognosis of GCC (eight patients administered BEP; six patients administered T-BEP) or a poor prognosis of GCC (one patient administered BEP; four patients administered T-BEP). PFS at 3 years (intent to treat) was 79.4% in the T-BEP group versus 71.1% in the BEP group (hazard ratio [HR], 0.73; CI, 0.47 to 1.13; P [log-rank test] = 0.153). PFS at 3 years in all eligible patients was 82.7% versus 70.1%, respectively (HR, 0.60; CI: 0.37 to 0.97) and was statistically significant (P = 0.03). Overall survival was not statistically different. Conclusion T-BEP administered with G-CSF seems to be a safe and effective treatment regimen for patients with intermediate-prognosis GCC. However, the study recruited a smaller-than-planned number of patients and included 7.7% ineligible patients. The primary analysis of the trial could not demonstrate statistical superiority of T-BEP for PFS. When ineligible patients were excluded, the analysis of all eligible patients demonstrated a 12% superior 3-year PFS with T-BEP, which was statistically significant.

7629 Background: Platinum-based chemotherapy is currently recommended as the standard approach for pts with advanced NSCLC. However prospective clinical trials specifically designed for elderly pts demonstrating the P benefit are still lacking. Therefore, we conducted a phase III trial to determine whether the addition of P to single agent-chemotherapy for elderly NSCLC pts could improve survival. Methods: Eligibility criteria included; chemotherapy-naive; stage III/IV NSCLC; age=70 and PS 0–1. Pts were randomized to receive either DP or D with minimization method balancing site, age (=74/=75) and stage (III/IV), and both regimens were given every 4 weeks. DP comprised D (20 mg/m2) and P (25 mg/m2) iv on days 1, 8, 15. D comprised D (25 mg/m2) iv on the same schedule. Primary endpoint was overall survival (OS). The planned sample size was 115 pts in each arm to provide 80% power to detect 0.667 hazard ratio for DP to D in OS and 2.5% one-sided alpha. Results: Between Apr 2003 and Apr 2006, 126 pts were randomized (D/DP: 63/63). The second planned interim analysis was performed on 112 assessable pts (D/DP:56/56, median age 76, =74/=75: 39/61%, male/female: 77/23%, PS 0/1: 39/61%, III/IV: 30/70%). Maturity of information, defined proportion of interim events to the planned events, was 26% (=49/191). As the one-sided p-value(p=0.00515) of the stratified log-rank test by age and stage was not lower than the critical value for the interim analysis, the formal criterion for stopping the trial failed to meet. However the Data and Safety Monitoring Board recommended study termination and disclosure of the results based on the strong interaction (two-sided p=0.077, hazard ratios [95% C.I.] for =74/=75: 0.23 [0.09–0.62]/0.72 [0.35- 1.49]) that DP may be beneficial for subgroup of age between 70- 74. Major Grade 3–4 toxicities were (%D/DP): neutropenia 4.9/13.1, anemia 1.6/16.4, anorexia 8.3/24.2, infection 11.7/8.1, pneumonitis 1.7/1.6. TRD occurred in 1 pt in DP arm. Conclusions: The interpretation of study results is limited due to early stopping and resultant loss of statistical power. But these data indicated that =74 young elderly have no more need to evaluate tolerability and efficacy of P. No significant financial relationships to disclose.

7575 Background: NVBo+P is considered as a standard treatment (trt) in M or LA NSCLC. The recent approval of Pem+P as front line chemotherapy (CT) for non-SCC demonstrates that today, histology could become a “new guidance” to treat patients (pts). Phase III trial (Scagliotti. JCO 2008) showed efficacy of Pem+P in patients with non-SCC pts. Moreover, the higher chemosensitivity of non-SCC is recognised and reported with other chemotherapies (Ardizzoni.JNCI 2007). In GLOB 3 study, NVBo+P also showed better survival in adenocarcinoma (11.7m) than in SCC (8.9m) (Tan.Ann of Oncol 2009). This trial was set up to assess the efficacy of NVBo+P compared to Pem+P for pts with non-SCC histological type. The primary end-point was disease control rate (DCR) including overall response rate (ORR) and stable disease (SD). Methods: Pts were randomised to receive NVBo 80 mg/m² D1D8 (60 at Cycle 1) + P 80 mg/m² D1 q3w or Pem 500 mg/m² + P 75 mg/m² D1 q3w. After 4 cycles of trt, for pts showing a disease control, single agent as continuation maintenance (CM) was proposed until progression or toxicity. Given that Pem+P is now considered as a reference trt in non-SCC, pts were randomised on a 2/1 basis and stratified according to stage (IIIB - IV - relapse), non-SCC confirmed by histology or cytology, gender, smoking status and centre. Results: From 10/09 to 02/11, 153 pts were randomised to receive NVBo+P (102 pts) or Pem+P (51 pts). The efficacy between the 2 arms is similar: The ORR/DCR (Recist 1.1) after 4 cycles of trt are 26%/75% in the NVBo arm (100 eval pts in ITT population) and 24%/78% in the Pem arm (50 eval pts in ITT population). At the end of December 2011, 7 patients are still treated in CM: 5 pts in the NVBo arm and 2 pts in the Pem arm. Conclusions: The 2 CT regimen, NVBo+P or Pem+P have a similar efficacy in terms of ORR/DCR for pts with advanced non-SCC NSCLC. These results appear to be in line with the published data. As the analysis is currently in progress, final results including safety data, PFS and OS will be presented during the meeting.

7017 Background: We previously reported the superiority of combined chemo-radiotherapy (CRT) over RT alone in elderly pts with locally advanced NSCLC (Atagi et al. ECCO2011). One and a half years follow-up data from last accrual are presented. Methods: Pts older than 70 years with unresectable stage III NSCLC were randomized to either RT alone (RT arm), a total dose of 60 Gy, or CRT arm including the same RT plus concurrent chemotherapy with carboplatin 30 mg/m2/day, 5 days/week × 20 days. The primary endpoint was overall survival (OS). The planned sample size was 100 pts in each arm with one-sided alpha of 5% and 80% power to detect a difference in median survival time (MST) from 10 months in RT arm to 15 months in CRT arm. Results: Between Sep 2003 and May 2010, 200 pts were randomized. Baseline characteristics were similar in the RT (n=100) vs CRT (n=100) arms: median age, 77 vs 77 years; stage IIIB (n), 46 vs 49; PS 0/1/2 (n), 41/55/4 vs 41/56/3. The second planned interim analysis was performed 10 months after the completion of accrual. In accordance with the pre-specified stopping rule, the JCOG Data and Safety Monitoring Committee recommended early publication of this trial because of the difference in OS favoring the CRT arm. In the updated analysis, OS was better in the CRT arm than the RT arm (HR = .64, 95% CI = .46-.89, one-sided p = .0033 by stratified log-rank test). In each arm (RT/CRT), MST was 16.5 mo/22.4 mo with 3-year OS of 14.3%/34.6%, response rate of 44.9%/54.6% (p=.201) and median progression-free survival of 6.9 mo/8.9 mo (p=.003). Gr 3/4 toxicities were (RT/CRT): neutropenia 0%/57.3%, infection 4.1%/12.5%, dysphagia 0%/1.0%, late RT toxicities 7.4%/7.5%. The pattern of relapse site and post-protocol treatment were almost similar between the arms. Even after an adjustment by the Cox regression analysis with six variables [stage, PS, sex, age, histology, smoking status], CRT arm showed better survival (HR=.71, p=.038). Conclusions: The CRT using daily carboplatin is considered to be the standard treatment for elderly pts with locally advanced NSCLC.

8043 Background: NVBo+P is considered as a standard treatment in M or LA NSCLC. The recent approval of Pem+P as front line chemotherapy (CT) for non SCC demonstrates that today, histology could become a “new guidance” to treat patients (pts). The importance of histological types was highlighted in a phase III trial (Scagliotti. JCO 2008). Moreover, the higher chemosensitivity of non SCC is recognised and reported with other chemotherapies (Ardizzoni. JNCI 2007). In GLOB 3 study, NVBo+P also showed better survival in adenocarcinoma (11.7m) than in SCC (8.9m) (Tan. Ann Oncol. 2009). This trial was set up to assess the efficacy of NVBo+P (Arm A) and Pem+P (Arm B) for pts with Non SCC histological type, evaluated in terms of Disease Control Rate (DCR) (SD+PR+CR). Methods: Pts were randomised to receive q3w NVBo 80 mg/m² D1D8 (60 at Cycle 1) + P 80 mg/m² D1 (Arm A) or Pem 500 mg/m² + P 75 mg/m² D1 (Arm B). After 4 cycles of combination, pts with DCR received single agent NVBo (Arm A) or PEM (Arm B) as maintenance until progression or toxicity. Pts were randomised on a 2/1 basis and stratified according to stage (IIIB - IV - relapse), non SCC confirmed by histology or cytology, gender, smoking status and centre. Results: From 11/09 to 02/11, 153 pts were randomised to Arm A (102 pts) or Arm B (51 pts). DCR after combination and maintenance was 75.0% (95% CI, 65.3 to 83.1) in Arm A and 76.5% (95% CI, 62.5 to 87.2) in Arm B. Median PFS was 4.2 (95% CI, 3.6 to 4.7) and 4.3 months (95% CI, 3.8 to 5.6) in Arm A and Arm B, respectively. Median OS was 10.2 months (95% CI, 7.8 to 11.9) and 10.8 months (95% CI, 7.0 to16.4) in Arm A and Arm B, respectively. During the combination period grade 3/4 neutropenia was 44.0% in Arm A and 18.3% in Arm B but febrile neutropenia was 2% in both arms; grade 3/4 thrombopenia was 0% and 6% in Arm A and Arm B, respectively. Conclusions: Even if the current results should be confirmed in a phase III study, the choice of a platinum-based doublet with oral vinorelbine as front-line chemotherapy could be a useful alternative in non SCC. Clinical trial information: 2009-012001-19.

232 Background: REACH was a global, multicenter, randomized, double-blind, phase 3 study evaluating the efficacy and safety of RAM as a single agent for the treatment of pts with advanced HCC after prior sorafenib therapy. The primary outcome for REACH was presented at ESMO 2014. The overall survival (OS) HR for the ITT population (RAM 283; placebo [PBO] 282) was 0.866 (95% CI 0.717, 1.046; p=0.1391); median OS was 9.2m for RAM vs 7.6m for PBO. The pre-specified subgroup analysis of baseline AFP (cutoff 400 ng/mL) suggested AFP is a predictive marker for RAM survival benefit. Methods: Pre-specified subgroup analysis was performed based on baseline AFP with a cutoff of 400 ng/mL. Additional analyses were conducted using stratified/unstratified cox regression models and corresponding log rank test to evaluate the relationship between baseline AFP and RAM treatment effect. Results: In 250 pts with baseline AFP ≥400 ng/mL (RAM 119; PBO 131), OS HR was 0.67 (95% CI 0.51–0.90; p=0.0059). Median OS was 7.8m for RAM vs 4.2m for PBO. In 417 pts with a baseline AFP ≥1.5 × upper limit of normal (ULN; RAM 205; PBO 212), mOS was 8.6m for RAM vs 5.7m for PBO and the HR was 0.749 (95% CI: 0.603, 0.930) (p=0.0088). The interaction testing of baseline AFP and RAM treatment effect on OS using both cutoffs (400 ng/mL and 1.5 xULN) are significant (p-value = 0.0272 and 0.0372, respectively). The safety profile in these pt populations was similar to that observed in the overall safety population. Additional REACH analyses demonstrating the predictive value of baseline AFP for RAM treatment effect on OS will be presented. Conclusions: A clinically meaningful improvement in OS was observed in populations with a baseline AFP ≥400 ng/mL or ≥1.5 × ULN. Additional analyses demonstrated a consistent RAM OS benefit for the pt population with baseline AFP over a wide range of values above the normal range. Baseline AFP is a likely predictive marker for RAM OS benefit. Clinical trial information: NCT01140347.
