Multicenter phase III randomized study of cisplatin and etoposide with or without bevacizumab as first-line treatment in extensive stage (ED) small cell lung cancer (SCLC) Dr. Andrea Ardizzoni, Dr. Marcello Tiseo Small Cell Lung Cancer: highlights • Decreased incidence (from 20% to 12%) • Revised histological classification (SCLC vs mixed SCLC-LC, WHO 2004) • Stage migration (< LD due to improved PET and brain MRI staging) • Cisplatin or carboplatin + etoposide (PE) remains the standard of care • 25 years of evaluating various CT cocktails have failed to produce a survival benefit over PE • Decreased scientific interest (orphan disease) Ardizzoni and Tiseo, Educational Book ASCO 2007 Why this trial in SCLC? • PE has reached an efficacy pleateu • New treatement with molecular targeted agents are necessary • No other ongoing or planned investigator-initiated randomized trials for first-line in Italy • SCLC is believed an ideal model for testing antiangiogenic drugs • The anti-angiogenic approach has allowed a significant step forward in other malignancies (colorectal, breast, renal cancer and NSCLC) Angiogenesis and SCLC • High vascularization by microvessel density count • Increased levels of serum VEGF have been reported in SCLC patients • SCLC express functional VEGFR-2 and VEGFR-3 • High serum and tumor levels of VEGF have been associated with poorer survival in some but not all studies • Serum VEGF levels may or may not correlate with extent of disease or response to chemotherapy Lucchi Eur J Cardio-Thoracic Surg 2002; Stefanou D Histol Histopathol 2004 Tanno S Lung Cancer 2004; Tas F Cancer Investigation 2006 Bevacizumab in Extensive Stage SCLC ECOG 3501 Cisplatin 60 mg/m2, D1 Etoposide 120 mg/m2, D1-3 Bevacizumab 15 mg/kg, D1 Q 21 days x 4 cycles Bevacizumab 15 mg/kg D1 q 3 weeks until PD Horn et al, J Clin Oncol 2009 CALGB 30306 Cisplatin 30 mg/m2, D1, 8 Irinotecan 65 mg/m2, D1, 8 Bevacizumab 15 mg/kg, D1 Q 21 days X 4 – 6 cycles Ready et al, J Clin Oncol 2011 Phase II Trials of Bevacizumab in ED-SCLC ECOG 3501: 65 pts CALGB 30306: 72 pts Median Survival 11.6 months OS PFS 6 month PFS: 30.2% Median PFS: 7 months 12-months 43.8% 1° Endpoint: 6 month PFS increased from 16% to 33% 1° Endpoint: to differentiate between 50 and 65% 12-months survival rates mPFS from 2.3 to 3.8 months Bevacizumab in Extensive Stage SCLC Randomized Phase II SALUTE trial Cisplatin 75 mg/m2, D1 or Carboplatin AUC 5, D1 Etoposide 100 mg/m2, D1-3 Bevacizumab 15 mg/kg, D1 or Placebo Q 21 days x 4 cycles Bevacizumab 15 mg/kg, D1 or Placebo q 3 weeks until PD End-point primario: PFS (HR: 0.70) Spigel et al, J Clin Oncol 2011 Bevacizumab in Extensive Stage SCLC Randomized Phase II SALUTE trial Spigel et al, J Clin Oncol 2011 Bevacizumab in Extensive Stage SCLC Randomized Phase II SALUTE trial Spigel et al, J Clin Oncol 2011 7505: Randomized phase II-III study of bevacizumab in combination with chemotherapy in previously untreated extensive small-cell lung cancer: Results from the IFCT-0802 trial – Pujol J-L et al • Study objective – Phase II study to assess the efficacy and safety of adding bevacizumab to first-line standard CT in extensive disease SCLC Key patient inclusion criteria • Extensive disease SCLC • ECOG PS 0–2 • Age ≤75 years • Weight loss <10% 2 x induction cycles of CT (cisplatin+ etoposide) or (cisplatin+ cyclophosphamide +epidoxorubicin+ etoposide) (n=147) 4 x cycles of CT (n=37) R 1:1 PD Stratification • ECOG PS, liver metastases, gender, induction CT, centre 4 x cycles of CT + bevacizumab 7.5 mg/kg q3w (n=37) Primary endpoint Secondary endpoints • Response rate 2 cycles after randomisation • PFS, OS, biomarkers, safety and QoL PD • Patients – Median number of CT cycles was 6 in both treatment arms Pujol et al.
