Brain Tumor Brain Metastases Brain Cancer | Radiation: Reduced Dose SRS | Not Applicable |
This is a prospective, single arm, pilot study to determine the symptomatic radiation necrosis rate at 6 months utilizing dose-reduced stereotactic radiosurgery with immunotherapy for subjects with a diagnosis of 1-10 brain metastases from MRI and tissue diagnosis of primary malignancy.
Primary end-point is 6 month symptomatic radiation necrosis, defined as a 6-month rate of clinical symptomatology requiring steroid administration (i.e. Decadron) and/or operative intervention concomitant with advanced and routine brain imaging findings consistent with radiation necrosis. Follow-up MRIs will be fused with the planning scan for this assessment.

Experimental: Reduced Dose Stereotactic Radiosurgery
Subjects will receive one stereotactic radiosurgery (SRS) treatment at a reduced dose based on the brain tumor size concurrently with their standard of care immunotherapy. Subjects will undergo follow up with clinical exams and brain MRI scans at 1, 3, 6, 9, and 12 months post SRS treatment

Radiation: Reduced Dose SRS
Subjects will receive SRS treatment at a reduced dose based on the brain tumor size |
- Symptomatic radiation necrosis rate [ Time Frame: 6 months post SRS ]Defined as the rate of clinical symptomatology requiring steroid administration (i.e. Decadron) and/or operative intervention concomitant with advanced and routine brain imaging findings consistent with radiation necrosis
- Local control rate [ Time Frame: 6 months, 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by Response Assessment in Neuro-oncology (RANO) criteria within the planning target volume
- Radiographic radiation necrosis rate [ Time Frame: 6 months, 12 months post SRS ]Defined as brain imaging findings on magnetic resonance imaging (MRI), magnetic resonance (MR) perfusion, MR Spectroscopy, and/or positron emission tomography (PET) imaging consistent with radiation necrosis.
- Symptomatic radiation necrosis rate [ Time Frame: 12 months post SRS ]Defined as the rate of clinical symptomatology requiring steroid administration (i.e. Decadron) and/or operative intervention concomitant with advanced and routine brain imaging findings consistent with radiation necrosis
- Gamma Knife local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects who receive SRS via gamma knife techniques
- Linear accelerator local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects who receive SRS via linear accelerator techniques
- Multi agent immune checkpoint inhibitor local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects who are treated with multi-agent immune checkpoint inhibitor therapy.
- Single agent immune checkpoint inhibitor local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects who are treated with single agent immune checkpoint inhibitor therapy.
- Melanoma brain metastases local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects with metastatic melanoma
- Non-melanoma brain metastases local control rate [ Time Frame: 12 months post SRS ]Defined as the rate of any new, recurrent, or progressing tumor as defined by RANO criteria within the planning target volume in subjects with non melanoma metastatic disease
- Gamma knife symptomatic radiation necrosis rate [ Time Frame: 12 months post SRS ]Defined as the rate of clinical symptomatology requiring steroid administration (i.e. Decadron) and/or operative intervention concomitant with advanced and routine brain imaging findings consistent with radiation necrosis in subjects who receive SRS using gamma knife techniques
- Linear accelerator symptomatic radiation necrosis rate [ Time Frame: 12 months post SRS ]Defined as the rate of clinical symptomatology requiring steroid administration (i.e. Decadron) and/or operative intervention concomitant with advanced and routine brain imaging findings consistent with radiation necrosis in subjects who receive SRS using linear accelerator techniques
