MO06.06 - Oral vinorelbine (NVBo) and cisplatin (P) or pemetrexed (Pem) and P as first-line chemotherapy for non squamous (NS) metastatic or locally advanced non small cell lung cancer (M or LA NSCLC): Final results of a prospective randomised phase II trial (NAVoTrial 1) (ID 276)

Background
NVBo and P are an established regimen in advanced NSCLC. The approval of Pem and P in NS NSCLC recognises histology as treatment driver even if the higher chemosensitivity of NS NSCLC is recognised and reported with other chemotherapies (Ardizzoni. JNCI 2007). NVBo + P also showed better survival in NS NSCLC than in Squamous NSCLC (Tan. Ann.Oncol. 2009). The current randomised (2:1) phase II trial assessed disease control (DCR) (SD + PR + CR) of NVBo/CDDP or PEM/CDDP in NS NSCLC.Methods
Stage IIIB/IV untreated/relapsed NS NSCLC 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, non PD pts 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 patients were enrolled in 31 centers and 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.Conclusion
Both doublets reported good efficacy and acceptable tolerability. The maintenance allowed continuation of effective treatment with either oral vinorelbine or pemetrexed as single agent, with an acceptable safety with both agents. These results are sufficiently compelling to consider whether a phase III randomised non inferiority study with oral vinorelbine maintenance after induction vinorelbine/cddp could be as effective as pemetrexed maintenance. An oral maintenance may be a definite advantage over intravenous maintenance.Only Members that have purchased this event or have registered via an access code will be able to view this content.

O02.01 - Geographic differences in the combined-modality treatment of stage III unresectable non-small cell lung cancer: Results from a global phase III trial of tecemotide (L-BLP25) (ID 2712)

Background
Chemo-radiotherapy (chemo/RT) is the standard of care for patients with unresectable stage III non-small cell lung cancer (NSCLC), but little is known about differences in clinical practice between regions of the world. The START trial is a global phase III trial of the MUC1-specific cancer immunotherapy tecemotide (L-BLP25), for which key efficacy and safety results have been reported previously. Here we report regional differences in diagnostic procedures and treatment of stage III NSCLC prior to enrolment in START.Methods
The START trial recruited patients (performance status 0/1) with unresectable stage III NSCLC who had not progressed within 28–84 days of completing ≥2 cycles of platinum-based chemotherapy with concurrent or sequential radiotherapy (≥50 Gy). Baseline characteristics, diagnostic procedures and the initial chemo/RT administered of those recruited were compared between centers in different regions.Results
From Jan 2007 to Nov 2011, 1513 patients were recruited at >250 centers in 33 countries: Western Europe 40.3%, Eastern Europe 26.0%, North America 21.8%, Latin America 5.7%, Asia 3.4%, Australia 2.8%. The majority of patients (92.1%) were Caucasian and median age was 61 years. Overall, 6.3% of patients were never-smokers with little inter-regional variation except for Asia (31.4%). The proportion of current smokers upon entry into the trial was highest in Eastern Europe (36.3%) and lowest in Australia (11.6%). Median tobacco consumption by region ranged from 36.2 (Eastern Europe) to 53.6 (Latin America) pack-years. The proportion of patients considered for the START trial who received concurrent rather than sequential chemo/RT varied widely between regions and was highest in North America and Australia, lower in Western Europe, Latin America and Asia, and lowest in Eastern Europe. There were also substantial variations in the diagnostic procedures between the regions, although pathological confirmation of N-status was infrequent in all regions. Detailed results by region for the time from diagnosis to randomization, duration of chemo- and radiotherapy, and chemotherapy agents used will be presented.Proportion of patients (%) with: Use of concurrent chemo/RT N-status determined with PET or PET/CT N-status determined with mediastinoscopy Australia (n=43) 100 74.4 2.3 North America (n=330) 92.7 37.9 18.5 Asia (n=51) 66.7 21.5 2.0 Latin America (n=86) 65.1 7.0 5.8 Western Europe (n=609) 67.2 32.2 6.9 Eastern Europe (n=394) 28.9 7.3 3.6 Conclusion
Baseline data from the START trial suggest substantial variations in the management of unresectable stage III NSCLC between different regions of the world. While recruited patients from North American and Australian centers mostly received concurrent chemo/RT in accordance with current recommendations, a substantial proportion of patients in Europe, Latin America and Asia received sequential chemo/RT. More frequent use of concurrent chemo/RT as the recommended standard of care should be made across geographic regions.Only Members that have purchased this event or have registered via an access code will be able to view this content.
