Brief Summary:
The primary objective of this Phase II study is to evaluate the progression-free survival at 6 months in adult subjects with a first recurrence of Glioblastoma Multiforme who are treated with MEDI-575.

Condition or disease Intervention/treatment Phase
Glioblastoma Multiforme Drug: MEDI-575 Phase 2

Detailed Description:

This is a Phase 2, multicenter, open-label, single-arm study to evaluate the antitumor activity, safety, and pharmacology of MEDI-575 in adult subjects with first recurrence of GBM.

Approximately 55 subjects will be enrolled to determine the preliminary efficacy profile of MEDI-575 in the treatment of subjects with first recurrence of GBM. Subjects will receive MEDI-575 as a 60-minute IV infusion on Day 1 every 21 days until disease progression, initiation of alternative anticancer therapy, unacceptable toxicity, or other reasons for subject withdrawal.

The primary assessment of antitumor activity is PFS-6; tumor response and progression will be determined using Updated Response Assessment Criteria of High Grade Gliomas- Neuro-Oncology Working Group v.1. Approximately 15 investigational sites in the United States will participate in this study. All subjects will be followed every 3 months for the duration of the trial (defined as 9 months from the date the last subject is entered into the trial or when the sponsor stops the study.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression-free Survival Rate at 6 Months [ Time Frame: 6 months ]
    Progression-free survival (PFS) rate at 6 months is defined as the proportion of participants who neither progressed nor died before 6 months after the first dose. Progression was determined using Updated Response Assessment Criteria of High Grade Gliomas: Response Assessment in Neuro-Oncology Working Group (RANO criteria). Progression was defined as at least 25% increase in measurement of enhancing lesions compared with the smallest tumor measurement obtained during the study; or significant increase in T2/fluid attenuated inversion recovery (FLAIR) nonenhancing lesion compared with baseline scan or best response; or any new lesion; or clear clinical deterioration; or failure to return for evaluation as a result of death or deteriorating condition; or clear progression of nonmeasurable disease. PFS-6 was estimated using Kaplan-Meier method.


Secondary Outcome Measures :
  1. Percentage of Participants With Best Overall Response [ Time Frame: Study entry through the end of the study, up to 21 months ]
    Best overall response rate is calculated based upon the disease assessments recorded during the study visits using RANO criteria. Best overall response includes complete response (CR), CR with confirmation, partial response (PR), PR with confirmation, stable disease and progressive disease. Confirmed responses are those that persist on repeat imaging studies at least 4 weeks after the initial documentation of response.

  2. Percentage of Participants With Objective Response [ Time Frame: Study entry through the end of the study, up to 21 months ]
    Objective response rate (ORR) is defined as the proportion of participants with confirmed CR or confirmed PR using RANO criteria. Confirmed CR and PR are those that persist on repeat imaging study for at least 4 weeks after the initial documentation of the response. CR is defined as complete disappearance of all enhancing measurable and nonmeasurable disease sustained for at least 4 weeks, no new lesions, stable or improved nonenhancing (T2/FLAIR) lesions, patient is off corticosteroids and stable or improved clinically. PR is defined as 50% decrease compared with baseline in the measurement of all measurable enhancing lesions sustained for at least 4 weeks, no progression of nonmeasurable disease, no new lesions, stable or improved nonenhancing (T2/FLAIR) lesions, no increase in the corticosteroid dose and stable or improved clinically.

  3. Time to Response
    Time to response (TTR) is defined as the time from the study entry to the first documentation of confirmed CR or confirmed PR. Analysis was based on responses confirmed at a repeat assessment made at least 4 weeks after the initial response, with the TTR taken as the first time the response was observed, not the confirmation assessment. TTR was estimated using Kaplan-Meier method.

  4. Duration of Response
    Duration of response is defined as the duration from the first documentation of objective disease response (ie, confirmed CR or confirmed PR) to the first documented disease progression. Duration of response was estimated using Kaplan-Meier method and evaluated only for the participants of subgroup with an objective response.

  5. Time to Progression [ Time Frame: Study entry until the first documented disease progression, up to 16 months ]
    Time to progression (TTP) is defined as time from the start of treatment with MEDI-575 until the documentation of disease progression. Disease progression was defined by at least 25% increase in measurement of enhancing lesions compared with the smallest tumor measurement obtained during the study; or significant increase in T2/FLAIR nonenhancing lesion compared with baseline scan or best response; or any new lesion; or clear clinical deterioration; or failure to return for evaluation as a result of death or deteriorating condition; or clear progression of nonmeasurable disease. TTP was estimated using Kaplan-Meier method.

  6. Progression-free Survival Rate at 3 Months and 9 Months [ Time Frame: 3 months and 9 months ]
    PFS rate at 3 and 9 months is defined as proportion of participants who neither progressed nor died due to any cause, whichever occurred first after first dose at 3 months and 9 months, respectively. Progression was defined as at least 25% increase in measurement of enhancing lesions compared with the smallest tumor measurement obtained during the study; or significant increase in T2/FLAIR nonenhancing lesion compared with baseline scan or best response; or any new lesion; or clear clinical deterioration; or failure to return for evaluation as a result of death or deteriorating condition; or clear progression of nonmeasurable disease. Proportion of participants with PFS at 3 and 9 months were estimated using Kaplan-Meier method.

  7. Progression-free Survival [ Time Frame: 9 months ]
    PFS was measured from the start of treatment with MEDI-575 until the documentation of disease progression or death due to any cause, whichever occurred first. Progression was defined as at least 25% increase in measurement of enhancing lesions compared with the smallest tumor measurement obtained during the study; or significant increase in T2/FLAIR nonenhancing lesion compared with baseline scan or best response; or any new lesion; or clear clinical deterioration; or failure to return for evaluation as a result of death or deteriorating condition; or clear progression of nonmeasurable disease. PFS was censored on the date of last tumor assessment documenting absence of tumor progression for participants who have no documented progression and were still alive prior to data cutoff, dropout, or the initiation of alternate anticancer treatment. Time to PFS was estimated using Kaplan-Meier method.

  8. Overall Survival [ Time Frame: Study entry to death, up to 16 months ]
    Overall survival is defined as the time from the start of treatment with MEDI-575 until death. For the participants who were alive at the end of study or lost to follow-up, Overall survival was censored on the last date when participants were known to be alive. The Overall survival was estimated using the Kaplan-Meier method.

  9. Percentage of Participants With Expression of PDGFR Alpha in the Tumor Samples [ Time Frame: Screening (Day-28 to Day -1) ]
    MEDI-575 (study drug) blocks platelet-derived growth factor (PDGF) binding to PDGF receptor (PDGFR) alpha and inhibits signaling. The tissue samples which were collected prior to the study entry (archived tumor samples) were evaluated by immunohistochemistry staining for expression of PDGFR alpha signaling protein that are targets of MEDI-575. Expression of PDGFR alpha in tumor cells and tumor-associated stromal cells were evaluated for intensity and distribution of staining. The percentage of participants with positive PDGFR alpha staining in the tumor cells and tumor-associated stromal cells were reported.

  10. Number of Participants With Treatment-emergent Adverse Events and Serious Adverse Events [ Time Frame: Baseline to last record on study, up to 21 months ]
    An adverse event (AE) is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. Treatment-emergent AEs (TEAEs) are AEs occurring or worsening after the administration of study drug until 90 days after the last dose of study drug or until the participant began another anticancer therapy, which ever came first. A serious AE (SAE) is any AE that results in death, is immediately life threatening, require (or prolong) inpatient hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly or birth defect, or is an important medical event that may jeopardize the participant or may require medical intervention to prevent one of the outcomes listed above. The TEAEs and SAEs were summarized using MedDRA version 15.1. Participants were counted only once for each event, regardless of number of events the participant had.

  11. Number of Participants With Worst ECOG Performance Status On-study and Last Record On-study [ Time Frame: Baseline to last record on study, up to 21 months ]
    Eastern Cooperative Oncology Group (ECOG) performance status is a scale that measures how cancer affects the daily life of a participant on an ordinal scale from grade 0 (fully active ie, best) to 5 (dead ie, worst). Following are ECOG grades: 0: Fully active, perform all pre-disease activities without restriction. 1: Restricted in physically strenuous activity but ambulatory, carry out work of a light or sedentary nature. 2: Ambulatory, capable of selfcare, unable to carry out any work activities, up and about more than (>) 50% of waking hours. 3: Capable of limited selfcare, confined to bed or chair >50% of waking hours. 4: Completely disabled, not capable of any selfcare, totally confined to bed or chair. 5: Dead.

  12. Treatment-emergent Adverse Events Related to Laboratory Parameters [ Time Frame: Baseline to last record on study, up to 21 months ]
    Laboratory evaluations of blood and urine samples were performed, including hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count with differential); serum chemistry (calcium, chloride, magnesium, potassium, sodium, aspartate transaminase, alanine transaminase, alkaline phosphatase, gamma glutamyl transferase, lactic dehydrogenase, carbon dioxide/bicarbonate, blood urea nitrogen, uric acid, creatinine, total bilirubin, glucose, albumin, total protein, triglycerides, cholesterol, phosphorous); urinalysis (pH, protein, blood, glucose, ketones, bilirubin); and coagulation parameters. Abnormal laboratory finding that required an action or intervention by the investigator, or a finding judged by the investigator to represent a change beyond the range of normal physiologic fluctuation, was reported as an AE. Number of participants with TEAEs related to laboratory evaluations were reported.

  13. Treatment-emergent Adverse Events Related to Electrocardiogram Evaluations [ Time Frame: Baseline to last record on study, up to 21 months ]
    All 12-lead electrocardiograms (ECGs) performed during the study were obtained in triplicate (ie, 3 ECGs were obtained within a 5-minute time period) and analyzed. Number of participants with TEAEs related to ECG after the start of study drug administration were reported. Participants were counted only once for each system organ class and preferred term, regardless of how many events the participants had.

  14. Treatment-emergent Adverse Events Related to Vital Sign Parameters [ Time Frame: Baseline to last record on study, up to 21 months ]
    Vital sign assessments were conducted throughout the study and included body temperature, blood pressure (seated), pulse rate and respiratory rate. The TEAEs related to vital signs in participants were reported. Participants were counted only once for each system organ class and preferred term, regardless of how many events the participants had.
