Primary Outcome Measures:
  • Fase I: To determine the MTD of nelfinavir as an adjuvant in the radiochemotherapy treatment in primary glioblastoma patients. Fase 2: Progression free survival at 6 months [ Time Frame: Fase 1: after treatment; fase 2: 6 months after treatment ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Fase 1/2: Incidence of acute toxicity; OS; Metabolic ratios of SUV of serial 18F-FDG: assessed by PET-CT.Fase 1:6-months PFS; Relative blood flow measurement by perfusion MRI. Fase 2: PFS at 12 months; Phosphorylation of AKT in tumour tissue. [ Time Frame: fase 1: 6 months after treatment; fase 2: 12 months after treatment ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 6
Study Start Date: March 2009
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: B Drug: nelfinavir
The start dose of nelfinavir in phase 1 is 1000mg BID. The maximum administered dose, if no DLT occurs, will be1250 mg BID (2500mg). Nelfinavir will be administered 1 week before start of the chemoradiotherapy until the last day of chemoradiotherapy.

Detailed Description:

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)
