Brief Summary:
This is an ongoing Phase 2, open-label, multicenter, non-randomized study of MEDI4736 (durvalumab) in subjects with glioblastoma (GBM) enrolled into 5 non-comparative cohorts. Primary study objectives, which vary by cohort due to differences in subject populations, include evaluation of the clinical efficacy as measured by the overall survival (OS) rate at 12 months (Cohort A), progression-free survival (PFS) at 6 months (Cohorts B, B2, and B3), and OS at 6 months (Cohort C). For all cohorts, secondary objectives include evaluation of the safety/tolerability and clinical efficacy of study treatment, and exploratory objectives include evaluation of the neurologic function and correlative biomarkers.

Condition or disease Intervention/treatment Phase
Glioblastoma Drug: Durvalumab Radiation: Standard radiotherapy Biological: Bevacizumab Phase 2

Detailed Description:

Eligible subjects are enrolled in parallel into one of the following 5 cohorts as described below. In each cohort, the first study drug administration for the first subject and the second subject are separated by at least 1 week.

  • Cohort A: Subjects with newly diagnosed unmethylated O^6-methylguanine-deoxyribonucleic acid methyltransferase (MGMT) GBM receive durvalumab (10 mg/kg every 2 weeks [Q2W]) + standard radiotherapy. The first 6 subjects are evaluated for dose-limiting toxicity (DLT) for 10 weeks to determine whether the durvalumab dose should be lowered to 3 or 1 mg/kg.
  • Cohort B: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) as monotherapy.
  • Cohort B2: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + bevacizumab (10 mg/kg Q2W).
  • Cohort B3: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + bevacizumab (3 mg/kg Q2W).
  • Cohort C: Bevacizumab-refractory subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + continued bevacizumab (10 mg/kg Q2W). The first 6 subjects are evaluated for DLTs for 6 weeks to determine whether the durvalumab dose should be lowered to 3 or 1 mg/kg.

The Core Study lasts for up to 12 months; optional extension treatment may be offered to subjects who complete 51 weeks of treatment on the Core Study with stable disease or better and upon agreement between the subject, Investigator, and Sponsor.

Subjects are followed on study for 90 days after the last drug administration and off study every 6 months for 3 years from the date of the first dose of study treatment.

The primary study endpoints have been met in Cohorts B (n=31), B2 (n=33), B3 (n=33), and C (n=22), although some subjects remain in treatment and/or follow-up and data collection is ongoing. Evaluation of the primary endpoint in Cohort A (n=40) is ongoing.

Primary Outcome Measures :
  1. Overall Survival Rate at 12 Months (OS-12) as Estimated Using the Kaplan-Meier Method (Cohort A) [ Time Frame: Up to 12 months ]
    OS-12 is the primary endpoint of Cohort A (not yet reached) and is the percentage of subjects who remain alive at 12 months, where OS is measured from the time of diagnosis until the recorded date of death or last follow-up. Subjects who are lost to follow-up at the time of the analysis will be censored on the date of last follow-up.

  2. Progression-free Survival Rate at 6 Months (PFS-6) as Estimated Using the Kaplan-Meier Method (Cohorts B, B2, and B3) [ Time Frame: Up to 6 months ]
    PFS-6 is the primary endpoint of Cohorts B, B2, and B3, and is the percentage of subjects who have not progressed at 6 months, with PFS measured from the date of the first dose of study treatment to the date of earliest disease progression (PD) based on modified Response Assessment in Neuro-Oncology (RANO) criteria or to the date of death, if PD does not occur. Per the RANO criteria, PD indicates any new lesion or a 25% increase in sum of the products of perpendicular diameters of enhancing lesions, or clear clinical deterioration per the Investigator (Wen et al. J Clin Oncol 2010; 28(11):1963-72).

  3. Overall Survival Rate at 6 Months (OS-6) as Estimated Using the Kaplan-Meier Method (Cohort C) [ Time Frame: Up to 6 months ]
    OS-6 is the primary endpoint of Cohort C and is the percentage of subjects who remain alive at 6 months, where OS is measured from the date of the first dose of study treatment until the recorded date of death or last follow-up. Subjects who are lost to follow-up at the time of the analysis will be censored on the date of last follow-up.


Secondary Outcome Measures :
  1. Number of Participants With Treatment-emergent Adverse Events [ Time Frame: Up to 15 months ]
    Toxicity is graded in accordance with the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.03. Adverse events (AEs) are reported based on clinical laboratory tests, vital sign and weight measurements, physical examinations, performance status evaluations, magnetic resonance imaging, and any other medically indicated assessments, including subject interviews, from the time informed consent is signed through 90 days after the last dose of durvalumab. AEs are considered to be treatment emergent if they occur or worsen in severity after the first dose of study treatment.

  2. Median PFS as Estimated Using the Kaplan-Meier Method (Cohorts B, B2, B3, and C) [ Time Frame: Up to 15 months ]
    PFS is measured from the date of the first dose of study treatment to the date of earliest PD based on modified RANO criteria or to the date of death, if PD does not occur. Per the RANO criteria, PD indicates any new lesion or a 25% increase in sum of the products of perpendicular diameters of enhancing lesions, or clear clinical deterioration per the Investigator (Wen et al. J Clin Oncol 2010; 28(11):1963-72).

  3. Median OS as Estimated Using the Kaplan-Meier Method (Cohorts B, B2, B3, and C) [ Time Frame: Up to 36 months ]
    All subjects are followed for survival at least every 6 months for up to 3 years following initiation of study treatment. In Cohorts B, B2, B3, and C, OS is measured from the date of the first dose of study treatment until the recorded date of death or last follow-up. Subjects who remain alive or are lost to follow-up at the time of the analysis are censored on the date of last follow-up.

  4. Number of Subjects With Best Overall Response (Cohorts B, B2, B3, and C) [ Time Frame: Up to 15 months ]
    Radiographic response is assessed by consistent imaging methods every (q) 8 to 9 weeks during study treatment administration. Response is categorized per the modified RANO criteria: complete response (CR) indicates no new lesions and disappearance of all disease sustained for ≥ 4 weeks; partial response (PR) indicates no new lesions, no progression of non-measureable disease, and ≥ 50% decrease from baseline in sum of products of perpendicular diameters of measurable lesions sustained for ≥ 4 weeks; stable disease (SD) indicates non-qualification for CR, PR, or progressive disease (PD); PD indicates any new lesion or a 25% increase in sum of the products of perpendicular diameters of enhancing lesions, or clear clinical deterioration per the Investigator (Wen et al. J Clin Oncol 2010; 28(11):1963-72).

  5. Mean Changes From Baseline in the European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-C30) [ Time Frame: Up to 12 months ]

    Health-related quality of life is measured using the validated EORTC-QLQ-C30. Questionnaires may be completed by the subject or with the assistance of the examiner at baseline prior to initiation of study therapy, and then approximately every 8 weeks while on study treatment (prior to discussing treatment response at each visit, whenever possible).

    All single questions are answered using a categorical scale (e.g., 1 = not at all; 2 = a little; 3 = quite a bit; 4 = very much) and linearly transformed to 0 to 100 scales with 1) higher scores for a functional scale representing higher levels of functioning, 2) higher scores for the global health status/quality of life representing higher levels of global health status/quality of life, 3) and higher scores for a symptom scale representing higher level of symptoms.


  6. Mean Changes From Baseline in the EORTC Brain Cancer Quality of Life Questionnaire (EORTC-QLQ-BN-20) [ Time Frame: Up to 12 months ]

    Health-related quality of life is measured using an EORTC quality of life questionnaire designed specifically for subjects with brain tumors (BN-20). Questionnaires may be completed by the subject or with the assistance of the examiner at baseline prior to initiation of study therapy, and then approximately every 8 weeks while on study treatment (prior to discussing treatment response at each visit, whenever possible).

    All single questions are answered using a categorical scale (e.g., 1 = not at all; 2 = a little; 3 = quite a bit; 4 = very much) and linearly transformed to 0 to 100 scales with 1) higher scores for a functional scale representing higher levels of functioning, 2) higher scores for the global health status/quality of life representing higher levels of global health status/quality of life, 3) and higher scores for a symptom scale representing higher level of symptoms.



Other Outcome Measures:
  1. Mean Changes From Baseline in Neurologic Function Using the Neurologic Assessment in Neuro-Oncology (NANO) Scale [ Time Frame: Up to 12 months ]

    Neurologic function is assessed using the NANO Scale (Nayak et al. Neuro-oncology 2013;15[Suppl 3]:iii123), an objective and quantifiable metric of neurologic function that incorporates direct observation and testing of 8 relevant neurologic domains designed to be evaluated quickly during a routine clinic visit. Level of function scores for each neurologic domain are evaluated by a physician, physician assistant or nurse practitioner at baseline prior to initiation of study therapy, and then approximately every 8 weeks while on study treatment.

    Domain functions are scored using a categorical scale ranging from 0 to 2 or 3, where higher scores represent a greater extent of functional impairment or abnormality (e.g., 0 = normal; 1 = mild/moderate impairment; 2 = severe impairment; 3 = complete impairment).
