RANDOMIZED PHASE II TRIAL AVAREG (ML25739) WITH
BEVACIZUMAB (BEV) OR FOTEMUSTINE (FTM) IN RECURRENT
GBM: FINAL RESULTS FROM THE RANDOMIZED PHASE II
TRIAL
Conclusions: BEV in recurrent GBM showed survival rates superimposable with FTM.

Aim: The treatment of recurrent glioblastoma (GBM) remains an open issue and the
role of BEV has been largely debated since only few data compared this agent with the
standard agents.
Methods: A multicenter, open label, randomized (2:1), non-comparative phase II study
(EudraCT 2011-001363-46; AVAREG - ML25739) with BEV 10 mg/m2 iv every 2
weeks or FTM 75 mg/m2 iv day 1-8-15 followed, after a 35 days interval, by FTM 100
mg/m2 every 3 weeks was conducted. Primary endpoint was overall survival at 6
months (OS6). Stratification factors were age (<55 years [yrs] or >55 yrs) and resection
for recurrent disease (yes vs no).
Results: 91 patients ( pts) with recurrent GBM were enrolled among 10 Italian centers
between 11/2011 and 9/2012. Median age was 57 yrs (range: 28-78), ECOG PS was 0/1/
2 in 42/35/14 pts. All pts received RT/TMZ accordingly with EORTC 26981-22981/
NCIC CE3. Time from diagnosis to 1st recurrence was 331 days in the BEV arm and
460 days in the FTM arm. At the time of recurrence, 21 pts (23.1%) underwent
re-resection before the inclusion into the study (13/8 pts in BEV/FTM arms,
respectively). Fifty-nine pts were enrolled in the BEV arm and 32 pts in the FTM arm.
OS6 was 62.1% (95%CI: 48.4 - 74.5) and 73.3% (95%CI: 54.1 - 87.7), OS9 was 37.9%
(95%CI: 25.5–51.6) and 46.7% (95%CI 28.3–65.7) in the BEV and FTM arms,
respectively. Median OS was 7.3 months (95%CI: 5.8 - 9.2) in the BEV arm and 8.7
months (95%CI: 6.3-15.4) in the FTM arm. In the BEV arm, OS6 and OS9 were 77.8%
(95%CI: 57.7–91.4) and 59.3% (95%CI: 38.8 - 77.6) in pts ≤55 yrs, and were 48.4%
(95%CI: 30.1 - 66.9) and 19.3% (95%CI: 7.4 - 37.5) in pts >55 yrs. HR for OS in BEV
group for pts >55 yrs compared with pts ≤55 yrs was 2.0 (95%CI: 1.0-4.1, p = 0.05).
