Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are:
* whether multiple doses of NSC-CRAd-S-pk7 are safe and feasible
* how multiple doses of NSC-CRAd-S-pk7 influence tumor response, overall survival, time to tumor progression, and quality of life.
Participants will:
* undergo a biopsy to confirm high grade glioma, then receive the first dose of NSC-CRAd-S-pk7 into the brain
* about 2 weeks later, undergo surgery to remove the tumor and receive the second dose of NSC-CRAd-S-pk7 into the brain
* start chemoradiation about 2 weeks after surgery, then about 2 weeks later, receive the 3rd dose of NSC-CRAd-S-pk7 into the brain
* four weeks later, at the end of chemoradiation, receive a fourth dose of NSC-CRAd-S-pk7 into the brain.
* after radiation is finished, receive standard of care chemotherapy and tumor-treating fields. Two additional doses of NSC-CRAd-S-pk7 will be given every 4 weeks.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Surgical phase:
Patients undergo a biopsy and upon intraoperative confirmation of high grade glioma, NSC-CRAd-S-pk7 dose #1 will be injected into the biopsy site. Patients will undergo resection of the tumor 14 (+/- 3) days later, administration of second dose of the investigational product (NSC-CRAd-S-pk7 dose #2), and implantation of the catheter system. The investigational product will then be given monthly for a total of 6 doses (see below).
Radiotherapy phase:
After recovery from surgery (usually within 2 weeks), standard chemoradiotherapy will be initiated consisting of daily radiotherapy (2 Gy per fraction x 30 fractions) and concomitant temozolomide (TMZ) chemotherapy (75 mg/m2 daily from day 1 of RT until last day of RT).
About 10-14 days into radiotherapy (= approx. 4 weeks after intraoperative dose #2), patients will be receiving NSC-CRAd-S-pk7 dose #3 through the previously implanted catheter system. This also marks the beginning of the formal dose-limiting toxicity (DLT) period, as this virus' survivin gene promoter is activated by the concomitant irradiation.
Four weeks later, ie. at the end of radiotherapy dose #4 is administered as previously, provided no DLT toxicity has been observed and viral treatment related toxicities have returned to grade ≤ 2.
Adjuvant (also called maintenance) phase:
As per standard of care, approx. 4 weeks after end of radiotherapy, patients will start maintenance TMZ chemotherapy (150 - 200 mg/m2, daily x 5 every 28 days) and loco-regional treatment with alternating Tumor Treating Fields (TTFields, Optune®). NSC-CRAd-S-pk7 doses #5 and #6 will be administered concurrently (± 3 days) with adjuvant cycle 1 and 2 of TMZ.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients must have presumed high grade glioma (WHO grade 3 or 4) based on clinical and radiologic evaluation for registration.
* A pathologic confirmation of high grade glioma must be made at the time of stereotactic biopsy prior to NSC-CRAd-S-pk7 injection; if this is not possible, the injection will not be performed and the subject will no longer be eligible for the study).

* Serum glutamic-oxaloacetic transaminase (SGOT or AST) \< 3x upper limit of normal
* Serum creatinine \< 2mg/dl
* Platelets \> 100,000/mm3 and white blood cells (WBCs) \> 3000/mm3
Exclusion Criteria
* Known hepatitis B or C infection, known HIV infection.
* Chronic use of immunosuppressive drugs (with exception of corticosteroids required for mass effect).
* Acute viral, bacterial or fungal infections requiring therapy.
* Pregnant or breast-feeding patients.
* Evidence of metastatic disease or other malignancy (except squamous or basal cell skin cancers).
