1 RANDOMIZED PHASE III TRIAL COMPARING FOLFIRINOX (5FU/leucovorin, irinotecan and oxaliplatin) VS GEMCITABINE AS FIRST-LINE TREATMENT FOR METASTATIC PANCREATIC ADENOCARCINOMA Prodige 4 - ACCORD 11/0402 trial: final results T.

2 Background Metastatic pancreatic ductal adenocarcinoma:
incurable disease few good treatment options Gemcitabine as single agent: cornerstone of treatment median survival: 6 to 7 mo. Gemcitabine-based combinations generally failed to increase survival Some trials suggested a possible benefit from combination chemotherapy in good performance status patients

3 Background Folfirinox regimen assessed in a phase II study (n=35)
promising regimen in good PS patients with M1 disease median survival of 9.5 months A phase II-III randomized study comparing Folfirinox regimen to gemcitabine alone was launched Results of phase II randomized study step (n=88) were presented during ASCO 2007: 31.8% RR in the Folfirinox arm vs 11.4% in the gemcitabine arm Due to these encouraging interim results, the trial continued as a phase III study.

4 Prodige 4 - ACCORD 11 trial design
6 months of chemotherapy recommended CT scans: obtained every 2 months for both arms: R A N D O M I Z E Folfirinox Metastatic pancreatic cancer Gemcitabine Stratification : center performance status: 0 versus 1 location of the tumor: head versus other location of the primary

5 Inclusion Criteria Histologically/cytologically confirmed pancreatic adenocarcinoma ECOG performance status of 0 or 1 Measurable metastases No prior cytotoxic chemotherapy No prior abdominal radiotherapy Age years Adequate hematopoietic, hepatic and renal function Bilirubin < 1.5 UNL No unstable angina or myocardial infarction within 12 months before entry Written informed consent

9 Endpoints Primary: overall survival Secondary:
objective response rate (RECIST) toxicity (NCI-CTC version 3.0 grading) progression-free survival (PFS) quality of life (EORTC QLQ-C30 v 3.0)

10 Statistical considerations
Hypothesis: Study designed to have 80% power to detect an increase in median overall survival from 7 to 10 months (HR 0.70) Sample size: 360 patients required to reach 250 events for final analysis, based on the use of the log-rank test with a two-sided significance level of 5% Planned interim analysis after observation of 167 events Intent to treat analysis (ITT)

11 Trial progress Recruitment: January 2005-October 2009
IDMC meeting, 30 September, 2009: Preplanned interim analysis after 192 events Recommendation to stop accrual: preplanned primary objective met (p <0.001) Final accrual of 342 patients Current analysis database frozen: 16 April, 2010 Number of deaths observed: 273 (73.4% of the sample size)

21 Time to definitive QoL degradation

22 Conclusions Folfirinox treatment resulted in a higher frequency of gr. 3/4 febrile neutropenia (5.4%), emphasizing the need for vigilant patient selection, education, monitoring, and active management Folfirinox regimen: is more toxic but has manageable toxicity Significantly improves PFS: reduced risk of disease progression by 53% Delays QoL degradation Significantly improves overall survival (HR 0.57, p<0.0001) : median survival 11.1 mo. Folfirinox recommended as new worldwide standard of care for patients with metastatic pancreatic cancer, bilirubin <1.5 UNL and PS 0-1 This combination will be tested in adjuvant setting
