2.Progression (according to RANO criteria) after prior radiation and temozolomide treatment
3.No more than 3 prior episodes of tumor progression
4.= 4 weeks between surgical resection or chemotherapy
5.= 12 weeks since last radiotherapy
6.Patients > 18 years of age.
7.Karnofsky performance status (KPS) of = 70%
8.Stable steroid dose for = 1 week
9.QT interval < 410 ms on ECG
10.Haematocrit >29%
11.ANC >10³ cells/µl
12.Platelet count >105/µl
13.Maximum 5 years since last Pneumovax (or equivalent) and varicella vaccination
14.Serum creatinine, AST and bilirubin = 1.5 times the IULN
15.Female patients of childbearing potential with a negative pregnancy test within 7 days of initiation of study treatment. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.
16.Male and female patients of reproductive potential who agree to employ an effective method of birth control throughout the study and for up to 6 months following discontinuation of study drug.*

13.Known HIV infection, active Hepatitis B or C infection
14.Any ongoing toxicity from prior anti-cancer therapy that is > grade 1 and/or that is progressing in severity (except alopecia) and delayed recovery following last temozolomide cycle
15.Additional anti-cancer treatment for glioblastoma other than study drug and supportive measures (i.e. dexamethasone)

Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective is to assess the safety and tolerability of the CUSP9v3 Treatment Protocol in patients with recurrent glioblastoma.;Secondary Objective: •Overall survival<br>•Progression-Free Survival<br>•Tumor Response<br>;Primary end point(s): The primary endpoint of this trial is the number of patients experiencing dose-limiting toxicity defined as:<br>-Either any unmanageable grade 3-4 toxicity at the end of the second treatment cycle<br>-Or inability to receive at least 7 of the 10 drugs, , all of them being given at =50% of the target doses<br>Modifications in terms of doses and/or number of drugs are accepted at any time during treatment.<br><br>;Timepoint(s) of evaluation of this end point: -Either any unmanageable grade 3-4 toxicity at the end of the second treatment cycle<br>-Or inability to receive at least 7 of the 10 drugs, will be decide at the weekly study visit within the inductioncycles
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): •Overall survival according to Kaplan-Meier estimates <br>•Progression-free survival according to Kaplan-Meier estimates <br>•Best tumor response according to the RANO criteria<br>;Timepoint(s) of evaluation of this end point: -Overall survival according to Kaplan-Meier estimates at every study visit (weekly; after three month every two weeks)<br>•Progression-free survival according to Kaplan-Meier estimates every month<br>Best tumor response according to the RANO criteria: after one year (end of Treatment) or at time of death
