This is a phase 2 study of oncolytic polio/rhinovirus recombinant (PVSRIPO) in adult patients with recurrent World Health Organization (WHO) grade IV malignant glioma.

Official Title

A Multicenter Phase 2 Study of Oncolytic Polio/Rhinovirus Recombinant (PVSRIPO) in Recurrent WHO Grade IV Malignant Glioma Patients


This is a phase 2 study of oncolytic polio/rhinovirus recombinant (PVSRIPO) in adult patients with recurrent World Health Organization (WHO) grade IV malignant glioma. The objectives of this study is to assess the efficacy and safety of PVSRIPO among adults with WHO grade IV malignant glioma at first or second recurrence. PVSRIPO will be delivered into intratumorally by convection-enhanced delivery (CED) using an intracerebral catheter placed within the enhancing portion of the tumor. All patients who receive PVSRIPO treatment will be included in efficacy and safety analyses.

Open to people ages 18 years and up

  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. Assuming patient meets all other criteria, site neurosurgeon must confirm placement of infusion catheter tip can occur ≥ 1cm from ventricles and at a safe distance relative to eloquent brain function.
  3. Tumor size and location requirements per protocol must be confirmed as qualifying and safe to proceed by the reviewer(s) designated by the Sponsor.
  4. 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:
  5. 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
  6. 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.
  7. If the male has had a vasectomy or is using a condom with spermicide, the female partner does not need to use additional birth control noted in 2a and 2b.
  8. Age ≥ 18 years of age at the time of entry into the study
  9. Karnofsky Performance Status (KPS) Score ≥ 70%
  10. Prothrombin and Partial Thromboplastin Times ≤ 1.2 x normal prior to biopsy
  11. Total bilirubin, serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase ≤ 2.5 x normal prior to biopsy
  12. Neutrophil count ≥ 1000 prior to biopsy
  13. Hemoglobin ≥ 9 prior to biopsy
  14. Platelet count ≥ 100,000/µL unsupported is necessary for eligibility on study; however, because of risks of intracranial hemorrhage with catheter placement, platelet count ≥ 125,000/µL is required for the patient to undergo biopsy and catheter insertion, which can be attained with the help of platelet transfusion
  15. . Creatinine ≤ 1.2 x normal range prior to biopsy
  16. . Positive serum anti-PV titer prior to biopsy
  17. . The patient must have received a boost immunization with trivalent inactivated IPOL™ (Sanofi-Pasteur) at least 1 week, but less than 6 weeks, prior to administration of the study agent
  18. . At the time of biopsy, prior to administration of virus, the presence of recurrent tumor must be confirmed by histopathological analysis.
  19. . A signed informed consent form (ICF) approved by the IRB will be required for patient enrollment into the study. Patients or their legally authorized representative (LAR) must be able to read and understand the informed consent document and must sign the informed consent indicating that they are aware of the investigational nature of this study
  20. . Able to undergo brain MRI with and without contrast

  2. Patients with an impending, life-threatening cerebral herniation syndrome, based on the assessment of the study neurosurgeons, their designate, and the reviewer designated by the sponsor
  3. Patients with severe, active co-morbidity, defined as follow:
  4. Patients with an active infection requiring intravenous treatment or having an unexplained febrile illness (Tmax > 99.5°F/37.5°C)

  11. Patients who have not recovered from the toxic effects of prior chemo- and/or radiation therapy. Guidelines for this recovery period are dependent upon the specific therapeutic agent being used.
  12. Patients may not have received tumor treating fields (≤ 1 week), chemotherapy or bevacizumab ≤ 4 weeks [except for nitrosourea and lomustine (≤ 6 weeks); metronomic dosed chemotherapy, such as daily temozolomide, etoposide or cyclophosphamide (≤ 1 week)] prior to starting the study drug.
  13. Patients may not have received immunotherapy ≤ 4 weeks prior to starting the study drug unless patients have recovered from side effects of such therapy.
