Phase I/II Study for Patients With Newly Diagnosed Glioblastoma Testing Nelfinavir in Combination With Concomitant Temozolomide and Radiotherapy.

Glioblastoma multiforme is the most malignant and common, about 50%, variant of all primary
brain tumours. The treatment strategies for this disease have not changed appreciably for
many years consisting of a surgical intervention (biopsy or tumour resection) and
post-operative local radiotherapy until several years ago. Combined chemoradiotherapy with
temozolomide is at the moment the standard medical practice after results of the joint
EORTC-NCIC phase III study randomizing between radiotherapy alone and combined
chemoradiotherapy with temozolomide showed a significant improvement in 2-years survival
from 8% to 24% for the combined treatment arm (Stupp 2005). Given the poor prognosis of
these patients and the still poor treatment response, further therapeutic improvement will
remain the most challenging topic for the future. The next step to further improve survival
for this patient group would be the addition of biological modifying and/or antiangiogenic
therapies. These strategies are motivated by the fact that glioblastomas often express very
high levels of vascular endothelial growth factor which is a key mediator of blood vessel
growth as high expression of EGFR, which upregulates the downstream PI3K-AKTpathway.
(Fischer I, Carmeliet P, Koul D) One possible candidate is nelfinavir, a protease inhibitor
interfering with Akt activity downstream of EGFR and upstream of VEGF. (Geng L, Gorski D,
HLu B)
