Brief Summary:
This is a randomized phase 2 study of oncolytic polio/rhinovirus recombinant (PVSRIPO) alone or in combination with the chemotherapy drug lomustine in adult patients with recurrent World Health Organization (WHO) grade IV malignant glioma.

Condition or disease Intervention/treatment Phase
Malignant Glioma Biological: PVSRIPO Drug: Lomustine Phase 2

Detailed Description:
This is a randomized phase 2 study of oncolytic polio/rhinovirus recombinant (PVSRIPO) alone or in combination with the chemotherapy drug lomustine in adult patients with recurrent World Health Organization (WHO) grade IV malignant glioma. The primary objective of this study is to assess the efficacy of a single dose of PVSRIPO alone or in combination with a single dose of lomustine among adults with WHO grade IV malignant glioma at first or second recurrence relative to the survival observed in a historical control group. The secondary objective is to determine the safety of each PVSRIPO treatment cohort in recurrent WHO grade IV malignant glioma patients. Within each cohort, the proportion of patients who experience grade 3, 4, or 5 AEs that are possibly, probably, and definitely related to protocol treatment will be estimated. Subjects will be randomized to receive either PVSRIPO alone, or PVSRIPO in combination with a single dose of lomustine 8 weeks after PVSRIPO infusion, to evaluate the impact of these treatment regimens on 24-month survival relative to historical controls. PVSRIPO will be delivered intratumorally by convection-enhanced delivery (CED) using an intracerebral catheter placed within the enhancing portion of the tumor. Based on experience with a Phase 1 study at Duke, previously published reports, and institutional review board (IRB)- and FDA-approved trials using similar infusion techniques, patients will be infused at a rate of 0.5 mL/hr. A Medfusion™ 3500 infusion pump (Smiths Medical, Minneapolis, MN) or any other comparable FDA-cleared syringe infusion pump approved by the sponsor or their designee, will be pre-programmed to a delivery rate of 0.5 mL/hr. Subjects randomized to the lomustine arm will receive a single oral dose of 110 mg/m^2 lomustine 8 weeks after PVSRIPO administration. If a subject has been treated with bevacizumab in the time since PVSRIPO infusion, the lomustine dose will be dispensed as an oral therapy at 90 mg/m^2 one time only 8 weeks after PVSRIPO infusion. The target accrual for the study is 62 patients, 31 patients per arm. All patients who are randomized and receive PVSRIPO treatment will be included in efficacy and safety analyses.

Primary Outcome Measures :
  1. 24-month overall survival [ Time Frame: 24 months after administration of PVSRIPO ]
    The percentage of participants alive at 24 months after the administration of PVSRIPO. Overall survival is calculated from the date of administration of PVSRIPO until the date of death, or the date of last follow-up if alive. Kaplan-Meier methods are used to estimate overall survival.


Secondary Outcome Measures :
  1. Percentage of participants with grade 3, 4, or 5 treatment-related adverse events [ Time Frame: Up to 24 months; events will be assessed continuously from the time of catheter placement for PVSRIPO administration until 30 days after a participant goes off study. ]
    The percentage of particpants with grade 3, 4 or 5 adverse events possibly, probably or definitely related to administration of PVSRIPO or Lomustine.

Criteria

Inclusion Criteria

  1. Patients must have a recurrent (first or second recurrence only, including this recurrence; transformation from a lower grade tumor to a WHO grade IV malignant glioma will be considered a first recurrence) supratentorial WHO grade IV malignant glioma based on imaging studies with measurable disease (a minimum measurement of 1 cm and maximum of 5.5 cm of contrast-enhancing tumor). Tumor size and location requirements will need to be confirmed by the reviewer designated by the Sponsor. Prior histopathology consistent with a WHO grade IV malignant glioma confirmed by the site's neuropathologist or the neuropathologist's designate
  2. If the subject is male and sexually active, he is eligible to enter and participate in this study if his partner(s) meets the criteria outlined in 2a or if he or his partner(s) is using one of the methods of birth control outlined in 2b. If the subject is female, she is eligible to enter and participate in this study if she meets the following criteria:

    1. Non-childbearing potential (i.e. physiologically incapable of becoming pregnant, including any female who is postmenopausal or surgically sterile). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Postmenopausal for purposes of this study, is defined as 1 year without menses); or
    2. Childbearing potential, has a negative serum pregnancy test at screening, and agrees to use one of the following methods of birth control: approved hormonal contraceptives (e.g. birth control pills, patches, implants, or infusions), an intrauterine device, or a barrier method of contraception (e.g. a condom or diaphragm) used with spermicide.
