10032 Background: We previously showed in the BFR14 study that IM interruption results in increased risk of disease progression (PD) after 1 and 3 years (yr) in non progressing patients (pts). The impact of IM discontinuation on progression free survival (PFS) in responding pts at 5 yrs is unknown. Methods: This prospective multicenter BFR14 study was initiated in 06/02 and completed inclusion in 05/09. After 1, 3, and 5 yrs of IM 400 mg/day, pts free from PD were randomly offered to continue (C arm) or Stop (S arm) IM. Pts allocated to the S arm had to restart IM (same dose) in case of PD. Primary endpoint was PFS. A Bayesian model was implemented for this part of the BFR14 study. Results: Overall, 434 pts were included in the BFR14 study. Fifty-eight (n=26 vs. n=32), 50 (n=25 vs. n=25) and 21 (n=11 vs. n=10) non progressive pts at were randomized at 1, 3 or 5 yrs in the S vs C arms. The 2 yr-PFS were 13% and 16% in the S arms after 1 and 3 years of treatment compared to 62% and 80% in the C arms after 1...
