E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether the addition of ABT-414 to concomitant radiotherapy and temozolomide prolongs overall survival (OS) in subjects with newly diagnosed GBM harboring EGFR amplificaton |
|
E.2.2 | Secondary objectives of the trial |
To determine whether the addition of ABT-414 to concomitant radiotherapy and temozolomide improves outcomes on the following: PFS, OS for EGFRvIII mutated tumor sub-group, PFS for EGFRvIII mutated sub-group, time to deterioration in neurocognitive functioning, time to deterioration in symptom severity and symptom interference scores of the MDASI-BT questionnaire, OS for the MGMT methylated subgroup |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
There is a pharmacogenetic sub-study optional translational and genetic sub-study for all subjects enrolled in the study. Amendment 3 includes an additional sub-study enrolling approximately 12 subjects with mild to moderate hepatic impairment. These subjects will receive open label ABT-414 and follow the same procedures and treatments as the blinded subjects in the blinded study. |
|
E.3 | Principal inclusion criteria |
1. de novo GBM tumors that test positive for EGFR amplification.
2. Age ≥ 18 years.
3. Karnofsky performance status ≥ 70 ≤ 14 days prior to randomization.
4. Must have recovered from effects of surgery, postoperative infection and other complications of surgery.
5. Adequate bone marrow, renal, and hepatic function ≤ 21 days prior to randomization. |
|
E.4 | Principal exclusion criteria |
1. multifocal, recurrent or metastatic GBM.
2. prior chemo therapy or radiosensitizer for cancer of the head and neck region.
3. prior radiotherapy to the head or neck resulting in overlap of radiation fields.
4. prior therapy for glioblastoma except surgery or other invasive malignancy.
5. prior, concomitant or planned treatment with anti-neoplastic intent including but not limited to Novo-TTF, EGFR-targeted therapy, bevacizumab, Gliadel wafers or other intratumoral or intracavity anti-neoplastic therapy. |

PFS, OS for EGFRvIII mutated tumor sub-group, PFS for EGFRvIII mutated sub-group, time to deterioration in neurocognitive functioning on the Hopkins Verbal Learning Test Revised (HVLT-R), time to deterioration in symptom severity score (MDASI-BT), time to deterioration on symptom interference score (MDASI-BT), OS for the MGMT methylated subgroup |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
MRIs will be performed every other cycle, HVLT-R and MDASI-BT performed at screening, prior initiation of adjuvant TMZ, and every 8 weeks thereafter. |
