· Patients > 18 years of age.
· ECOG performance status of ≤ 2 (stable over 4 weeks prior to study entrance)
· 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.
· 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.*
· Signed informed consent prior to initiation of any study procedure |
|
E.4 | Principal exclusion criteria |
· Female patients who are pregnant or breast-feeding
· History of severe hypersensitivity reaction (≥grade 3) to any component of the investigational drugs or excipients (allergy to or other intolerability of gadolinium, docetaxel, cabazitaxel or polysorbate 80 containing drugs)
· Unable to undergo Gd-MRI
· Time since external beam radiotherapy <12 weeks
· Patients who have been treated with any investigational agent(s) within 28 days of the first day of administration of study drug.
· Current active second malignancy other than non-melanoma skin cancers and post-treatment of localized prostate cancer. Patients are not considered to have a currently active malignancy if they are in complete remission for > 3 years prior to study
· Uncontrolled severe illness or medical condition (including uncontrolled diabetes mellitus)
· Known HIV infection, active Hepatitis B or C infection
· Any serious and/or unstable pre-existing psychiatric or other condition that could interfere with subject’s safety, provision of informed consent, or compliance to study procedures
· Any ongoing toxicity from prior anti-cancer therapy that is > grade 1 and/or that is progressing in severity (except alopecia) and delayed hematological recovery following last temozolomide cycle
· Additional anti-cancer treatment for GBM other than study drug and supportive measures (i.e. dexamethason)
· Inadequate organ and bone marrow function as evidenced by:
a) Hemoglobin <9.0 g/dL
b) Absolute neutrophil count <1.5 x 109/L,
c) Platelet count <100 x 109/L,
d) AST/SGOT and/or ALT/SGPT >2.5 x ULN;
e) Total bilirubin >1.0 x ULN,
f) Serum creatinine >1.5 x ULN.
If creatinine 1.0 - 1.5 x ULN, creatinine clearance will be calculated
according to CKD-EPI formula and patients with creatinine clearance <60 mL/min should be excluded |

E.5 End points |
E.5.1 | Primary end point(s) |
• Response including SD, PR or CR determined by MRI (modified RANO criteria) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The response to treatment will be evaluated continuously after every two treatment cycles (in 42 day intervals) using the response criteria defined by the Response Assessment in Neuro-Oncoloy Working Group (RANO, Wen et al., 2010; Appendix
III). |
|
E.5.2 | Secondary end point(s) |
Primary Endpoint
· Overall and progression-free survival
· Safety and tolerability
· Pharmacokinetics data concerning drug interactions (i.e. CYP3A
induction)
· Quality of life and neurocognitive functioning
Safety endpoints
· Rates of deaths within 12 weeks
· Hematological and non hematological toxicity grade ≥ 2 according to CTCAE V4.0 |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
A first safety assessment will be performed after treatment of 12 patients. Safety assessment will be based on an observation period of each patient of at least four cycles (12 weeks). |
