Lerapolturev (PVSRIPO) in GBM
What this study is about
The purpose of this research study is to determine the safety and effectiveness of administering two doses of lerapolturev in residual disease (within tumor margins) after surgery, followed later by repeated injections of lerapolturev in the injected under the skin area (under the skin) around the lymph nodes of the head and neck for adult patients diagnosed with recurrent glioblastoma at the Preston Robert Tisch Brain Tumor Center (PRTBTC) at Duke.
View original scientific description
The purpose of this research study is to determine the safety and efficacy of administering two doses of lerapolturev in residual disease (within tumor margins) after surgery, followed later by repeated injections of lerapolturev in the subcutaneous area (under the skin) around the lymph nodes of the head and neck for adult patients diagnosed with recurrent glioblastoma at the Preston Robert Tisch Brain Tumor Center (PRTBTC) at Duke.
Interventions
DRUG
Lerapolturev
Lerapolturev (intratumoral) will be dosed at 2x108 TCID50 in 3.0 mL x 2 doses (total dose 4x108 TCID50) by Convection Enhanced Delivery. For the patients randomized to the lerapolturev Arm 1 of Stage 2, seven days (±2 days) following completion of the 2nd intratumoral infusion of lerapolturev, patients will begin cervical perilymphatic subcutaneous injection of lerapolturev at a dose of 2 x 108 TCID50 (in 0.5 ml diluent) around the cervical lymph node chain ipsilateral to the intracranial tumor.
DRUG
Lomustine Pill
Lomustine will be given as a single oral dose of 110 mg/m2 every six weeks for up to 9 cycles.
Primary outcome measures
Proportion of patients at each dose level who experienced a dose-limiting toxicity - Stage 1
Time frame: Up to 1 year
Dose-limiting toxicities (DLTs) are defined as any of the following events that are possibly, probably, or definitely attributable to study treatment (i.e., lerapolturev) during dose escalation (Stage 1): * Any Grade 3 or any Grade 4 toxicity within 2 weeks, including cerebral edema or worsening neurologic symptoms * Any life-threatening event within 2 weeks * Treatment-related death at least possibly, probably, or definitely attributable to study treatment * Any grade 2 or higher serious cytokine release syndrome at least possibly, probably, or definitely attributable to study treatment, particularly those affecting vital organs (e.g., cardiac, hepatic, renal, CNS) occurring within 2 weeks of the infusion
Proportion of patients who experience an unacceptable toxicity - Stage 2
Time frame: Up to 1 year
Unacceptable toxicity is defined as any of the following events that are possibly, probably, or definitely attributable to study treatment: * Any Grade 3 or any Grade 4 toxicity within 2 weeks, including cerebral edema or worsening neurologic symptoms * Any life-threatening event within 2 weeks * Treatment-related death at least possibly, probably, or definitely attributable to study treatment * Any grade 2 or higher serious cytokine release syndrome at least possibly, probably, or definitely attributable to study treatment, particularly those affecting vital organs (e.g., cardiac, hepatic, renal, CNS) occurring within 2 weeks of the infusion
Overall survival (OS) - Stage 2
Time frame: 2 years
Median OS, where OS is defined as the time between randomization and death
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Age ≥ 18 years old at the time of entry into the study.
- Histopathologically confirmed recurrent supratentorial glioblastoma (WHO grade 4) (high grade glioma with molecular features of glioblastoma will be eligible).
- Karnofsky Performance Score (KPS) ≥ 70%
- Hemoglobin ≥ 9 g/dl prior to biopsy
- Platelet count ≥ 100,000/µl unsupported is necessary for eligibility on the 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.
- Neutrophil count ≥ 1000 prior to biopsy
- Creatinine ≤ 1.5 x normal range prior to biopsy
- Total bilirubin ≤ 1.5 x ULN prior to biopsy (Exception: Participant has known or suspected Gilbert's Syndrome for which additional lab testing of direct and/or indirect bilirubin supports this diagnosis. In these instances, a total bilirubin of ≤ 3.0 x ULN is acceptable.)
- AST/ALT ≤ 2.5 x ULN
- Prothrombin and Partial Thromboplastin Times ≤ 1.2 x normal prior to biopsy. Patients with prior history of thrombosis/embolism are allowed to be on anticoagulation, understanding that anticoagulation will be held in the perioperative period per the neurosurgical team's recommendations. Low molecular weight heparin (LMWH) is preferred. If a patient is on warfarin, the international normalized ratio (INR) is to be obtained and value should be below 2.0 prior to biopsy.
- At the time of biopsy, prior to administration of the 1st infusion of lerapolturev via CED, the presence of recurrent tumor must be confirmed by histopathological analysis.
- Able to undergo brain MRI with and without contrast
- Prior CDC-recommended vaccination series against PV and has received a boost immunization with trivalent Poliovirus Vaccine Inactivated (IPOL®) (Sanofi-Pasteur SA) at least 1 week, but less than 6 weeks, prior to administration of lerapolturev. Note: Patients who are unsure of their prior vaccination status must provide evidence of anti-PV immunity prior to enrollment, as applicable.
- Patient or partner(s) meets one of the following criteria:
- Non-childbearing potential (i.e., not sexually active, physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile, or any male who has had a vasectomy). 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
- Childbearing potential 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.
- A signed informed consent form approved by the Institutional Review Board (IRB) will be required for patient enrollment into the study. Patients 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
