Open to people ages 18 years and up
- ≥ 18 years of age.
- Recurrent supratentorial glioblastoma confirmed via prior histology by the site's neuropathologist or designate.
- Histologically confirmed recurrent glioblastoma within 6 weeks of Lerapolturev infusion will not require a biopsy to confirm active tumor prior to catheter placement
- Progression of primary glioblastoma or transformation from a lower grade to a higher grade is acceptable for recurrence and as for primary glioblastoma, must be confirmed via prior histology by site pathologist
- Enhancing lesion ≥1 cm shortest diameter to ≤ 5.5 cm longest diameter in all planes.
- Before catheter placement based on screening MRI and at the time of catheter placement via CT prior to infusion, neurosurgical investigator must confirm placement of infusion catheter within or through the progressive enhancing tumor is feasible and at a safe distance relative to eloquent brain function, with the tip of the catheter being placed:
- Within the enhancing portion or in the vicinity of enhancement of target lesion (ie, infiltrative disease).
- ≥ 0.5 cm from ventricles.
- ≥ 1 cm deep into the brain.
- ≥ 0.5 cm from corpus callosum.
- First or second relapse supported by MRI or CT scan; relapse is defined as progression following initial/prior therapy(ies).
- Failed previous first line therapy: maximum surgical resection and radiotherapy (RT) (plus concomitant chemotherapy followed by maintenance chemotherapy if unknown or methylated O6-methylguanine-DNA methyltransferase (MGMT) promoter). Patients who begin but do not complete chemotherapy/RT may still be considered for eligibility at the discretion of Sponsor.
- Karnofsky Performance Status ≥ 70 at screening and baseline.
- Undergone prior vaccination against PV and received a boost immunization with trivalent inactivated poliovirus vaccine (IPOL®) at least 1 week, but less than 6 weeks, prior to administration of Lerapolturev. Note: Patients who are unsure of their prior vaccination status/who have not been vaccinated must provide proof of vaccination and/or evidence of anti-PV immunity prior to enrollment, as applicable.
- Ability to safely discontinue anti-coagulant therapy(ies) prior to biopsy/catheter placement, as required per site/surgical guidelines.
- . Hemoglobin ≥ 9 g/dL prior to biopsy/catheter placement.
- . Platelet count ≥ 100,000/μL (unsupported); ≥ 125,000/ μL (can be supported via platelet transfusion) at biopsy/catheter placement.
- . ANC ≥ 1000/μL prior to biopsy/catheter placement.
- . Creatinine ≤ 1.2 x ULN prior to biopsy/catheter placement.
- . Total bilirubin, ALT, AST, ALP ≤ 2.5 x ULN prior to biopsy/catheter placement.
- . PT and aPTT ≤ 1.2 x ULN prior to biopsy/catheter placement.
- . If undetectable ATT IgG at screen, Tdap booster vaccine ≥ 1 week prior to biopsy/catheter placement.
- . Patients must be willing and able to understand and provide written informed consent.
You CAN'T join if...
- Received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti- CTLA-4 antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways) ≤ 12 weeks prior to lerapolturev infusion (Note: does not apply for patients treated with pembrolizumab under this protocol who are eligible for lerapolturev retreatment). Note: patients who had previously permanently discontinued any anti-PD-1 or PD-L1 therapy due to severe or life-threatening immune-related AE are excluded.
- Excluded are:

- Tumors with ≥ 1cm of contrast-enhancing tumor component crossing the midline (crossing the corpus callosum).
- Extensive subependymal disease: multiple lesions or lesions covering > 50% of subependymal space. Tumor touching subependymal space allowed.
- Extensive leptomeningeal disease: multiple lesions or lesions covering > 50% of leptomeninges. Tumor touching leptomeninges allowed.
- Has received systemic immunosuppressive treatments other than systemic corticosteroids (eg, methotrexate, chloroquine, azathioprine) within six months of Lerapolturev infusion.
- Requires treatment with high dose systemic corticosteroids, defined as dexamethasone > 4 mg/day or equivalent, within 2 weeks of Lerapolturev infusion.
- Prior interstitial brachytherapy, implanted chemotherapy, stereotactic radiosurgery or therapeutics delivered by local injection or CED, including Lerapolturev (except for qualifying patients being retreated with Lerapolturev within this trial).
