Preoperative radiosurgery for high grade glioma treatment

Preoperative Radiosurgery in High Grade Glioma: A Phase I Clinical Trial: The NeoGlioma Study

Phase 1 Interventional Mayo Clinic · NCT05030298

What this trial studies

This phase I trial investigates the feasibility, safety, and maximum tolerated dose of preoperative radiosurgery in patients with biopsy-proven high-grade glioma. The approach involves using MRI-guided stereotactic biopsy followed by a single large dose of radiation to the tumor before conventional surgery. The study aims to evaluate the acute toxicity profile, radiographic tumor control, and overall survival rates post-surgery. Additionally, it includes correlative research to understand tumor repair pathways and immune profiling.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with confirmed high-grade glioma who are scheduled for neurosurgical resection.

Not a fit: Patients with low-grade gliomas or those who are not candidates for surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve tumor control and reduce treatment-related side effects for patients with high-grade glioma.

How similar studies have performed: Other studies have shown promise with preoperative radiosurgery approaches, suggesting potential for success in this novel application.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age \>= 18 years
* Clear clinical and radiographic evidence of primary high grade glioma (HGG) as judged by the Mayo multidisciplinary neuro-oncology team (World Health Organization \[WHO\] grade III-IV, including glioblastoma) regardless of IDH and MGMT status
* Patients who underwent a previous biopsy confirming high grade glioma are eligible for enrollment
* Planned neurosurgical resection of tumor
* Judged to not be at risk of significant clinical risk (i.e. herniation) with radiation-induced edema prior to resection
* Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2
* Negative pregnancy test done =\< 14 days prior to registration, for women of childbearing potential only. Patients over 50 years of age who decline pregnancy testing are still eligible without a pregnancy test.
* Ability to complete questionnaire(s) by themselves or with assistance
* Provide written informed consent
* Willing to receive adjuvant radiotherapy at enrolling institution at the time of registration
* Willing to provide tissue and/or blood samples for correlative research purposes

Exclusion Criteria:

* Any of the following:

  * Pregnant women
  * Nursing women who are unwilling to cease during therapy
  * Men or women of childbearing potential who are unwilling to employ adequate contraception
* Prior history of cranial radiotherapy
* Unwillingness to participate in study
* Investigator discretion that enrollment on the study would pose undo harm or risk to the patient
* Non-MRI compatible implanted medical device
* Use of systemic anti-cancer therapy within the previous 3 months
* Medical contraindication to craniotomy and tumor resection
* Pathologic confirmation of grade I-II glioma, brain metastasis, or other brain tumor

  * Note: Patients with a history of grade I-II glioma are eligible if they have only received surgery as treatment and now there is concern for transformation to grade III-IV tumor
* Primary spinal cord glioma or primary brainstem glioma
* Residual tumor of excessive volume or eloquent location per investigator discretion
* Patients who are unwilling or unable to comply with study procedures
