Clinical Trials

The purpose of this study is to characterize the effectiveness of belzutifan for patients with VHL disease-associated RCC and/or CNS hemangioblastoma treated in real-world clinical practice. The primary effectiveness parameter includes tumor reductive procedures given the clinical importance of this parameter and association with subsequent morbidity and mortality of disease. 

This study aims to demonstrate that the efficacy of treatment with selumetinib as measured by event-free survival (EFS) is non-inferior compared to treatment with carboplatin/vincristine (CV) in previously-untreated low-grade glioma (LGG) not associated with BRAFV600E mutations or systemic neurofibromatosis type 1 (NF1).

This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. Patients will be more likely to be randomized to proton beam radiation therapy. It is not yet known if ...

The purpose of this study is to evaluate the use of fluorine F 18 fluorodopa-labeled PET scanning for the planning of surgery and radiation therapy to treat patients who have newly diagnosed high- or low-grade glioma brain tumors. New imaging procedures, such as fluorine F 18 fluorodopa-labeled PET scans, may help in guiding surgery and radiation therapy and allow doctors to plan better treatment.

The purpose of this study is to collect and store brain tissue samples and blood from children with brain cancer that will be tested in the laboratory. Collecting and storing samples of tumor tissue and blood from patients to test in the laboratory may help the study of cancer in the future.

The purpose of this study is to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 1 meningioma as measured by 6-month PFS rate, and to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 2 or 3 meningioma as measured by 6-month PFS rate.

The primary objectives of this study are to determine the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of selumetinib + vinblastine for children with progressive or recurrent LGGs, and to determine if selumetinib + vinblastine will lead to improved event-free survival (EFS) outcome compared with selumetinib alone for children with progressive or recurrent LGGs.

The purpose of this study is to evaluate the side effects and best dose of nivolumab when given together with multi-fraction stereotactic radiosurgery and to see how well they work with or without ipilimumab in treating participants with grade II-III meningioma that has come back. Monoclonal antibodies, such as nivolumab and ipilimumab, may interfere with the ability of tumor cells to grow and spread. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. It is not yet known whether giving nivolumab and multi-fraction ...

The purpose of this study is to evaluate the benefit of using intravenous fluorescein sodium (FS) and YELLOW 560 nm microscope filter (YE560) during surgery for vestibular schwannomas (VS), Meningioma, Head and Neck Paraganglioma, or Head and Neck Schwannoma and to determine the optimum FS dose and timing to be used with the YE560 device.

Acoustic neuromas (also known as vestibular schwannomas) are benign slow growing tumors that arise from the vestibular portion of the eighth cranial nerve. Current treatment options include microsurgery, stereotactic radiosurgery and observation, using a “wait-and-scan” approach. The primary objective of this study is to compare long-term quality of life outcomes between treatments for sporadic acoustic neuromas.

The goal of this study is to investigate the feasibility of successfully obtaining intra-operative OCT imaging and data during standard brain surgery.

The intent is to collect relevant clinical data on patients exposed to Agent Orange plus assessment of the tissue for genetic mutations known to be associated with growth of thyroid cancer and pituitary tumors and report our findings as a descriptive case series.

The purpose of the study is to conduct cognitive testing of the recently published Mayo Clinic Vestibular Schwannoma Quality of Life (VSQOL) Index.

The purpose of this registry is to collect clinical, diagnostic, and therapeutic data specific for primary spinal column tumor patients, and evaluate it to understand the predictive factors which influence survival, local recurrence, adverse events, perioperative morbidity, and health related quality of life.

The purpose of this data registry involves the collection of standard of care clinical treatment regimens, diagnostic information and surgical outcomes which may include human specimens and associated genomewide expression data.  

The objectives of this study are to determine the impact of omega-3 supplementation on promoting facial nerve function recovery, and to determine the impact of omega-3 supplementation on Vestibular schwannoma (VS) tumor control.

The objective of the study is to evaluate efficacy and safety of zanzalintinib in participants with recurrent or progressive meningioma refractory to standard therapies.

The purpose of this study is to evaluate the effectiveness and safety of  ATR-101 for the treatment of adults who have internally caused Cushings syndrome.

The purpose of this study is to investigate if a blood test measuring copeptin within 24 hours following pituitary surgery could predict development of diabetes insipidus (increased urination and thirst with fluid balance problems) as opposed to the clinical methods we currently use.

The purpose of this research is to evaluate the diagnostic role and clinical efficacy of [18F]FET-PET/MRI in detecting MRI-occult primary or residual/recurrent functional pituitary adenomas (PAs) and its influence on clinical and surgical decisions.

This trial will evaluate the safety and tolerability of a single unilateral administration of one of three dose levels of AAVAnc80-antiVEGF and will evaluate the Akouos delivery device to safely achieve the intended product performance.

The purpose of this study is to develop and validate a new disease-specific, quality-of-life (QOL) index for sporadic Vestibular Schwannoma (VS) that addresses key shortcomings of previous instruments.

The purpose of this study is to evaluate the performance [sensitivity, specificity, accuracy] of 18Fluoro-O-(2) fluoroethyl-L-tyrosine (FET) PET/CT imaging to detect ACTH-secreting pituitary adenoma, using operative findings and histopathology as truth standard.

The objectives of this study are to:

• • Measure the short and long-term overall and nasal-specific quality of life (QOL) impact of patients undergoing Endoscopic Endonasal Skull Base Surgery (EESBS) for pituitary and sellar lesions.
  • Determine the relative difference in QOL impact of EESBS for patients undergoing surgery for functional and nonfunctional pituitary adenomas.

The objectives of this study are to survey patients during the post-operative period regarding their experience with fluid restriction including adherence and discomfort, and to document rates of hyponatremia and readmissions in post-operative patients.

Advances in endonasal, endoscopic transsphenoidal surgical techniques have decreased complications and length of stay for persons undergoing resection of sellar and suprasellar masses  Previous research by investigators now at Mayo (SLS, AQH) has shown that particular interventions including fluid restriction post-operatively decrease patient morbidity (e.g., from hyponatremia) and readmissions while maintaining patient safety. However, the patient perspective on the impact of fluid restriction has not ...
