An Optimization Study Evaluating Safety and Efficacy of the Y-90 Glioblastoma (GBM) Device in Patients With Recurrent GBM

Korábbi kezelés

• Have received more than 1 course of prior cerebral radiotherapy (EBRT)
• Prior cranial radiation dose ≥ 66 Gy
• Have received radiosurgery, brachytherapy, or hypofractionated radiotherapy
• Have received more than 2 systemic anti-tumor treatment protocols (lines of treatment), not including neoadjuvant or adjuvant temozolomide (oral or IV)
• Have received more than 2 surgical GBM-related procedures
• Are at increased risk of wound dehiscence by the discretion of the investigators (e.g. recent brain surgery, poor skin condition, and/or previously infected surgical field or any other condition that is of increased infectious risk in the opinion of the treatment team)
• Patients with a history of an active other malignancy within 1 year prior to index procedure. NOTE: Exceptions to this requirement include adequately treated non-melanoma skin cancer or carcinoma in situ without evidence of disease
• Subject is currently participating, or plans to participate in, another investigational trial that may confound the results of this trial (unless written approval is received from the Boston Scientific study team).

Más betegség

• Have leptomeningeal disease or other primary malignancy metastatic to the brain
• Patients with a history of stroke, ischemic cerebral disease, and/or at risk of cerebral herniation
• Have uncontrolled epilepsy
• Have severe and/or insufficiently controlled intercurrent illness; patients with the following are not eligible:
  • Hypertension grade 3 or higher without adequate control on medications
  • Symptomatic or unstable cardiac disease,
  • Ongoing or active bacterial or viral infection requiring systemic treatment (including HIV)
  • Psychiatric illness/social situations that would limit compliance with study requirements
  • Peripheral Neuropathy ≥ grade 1
  • Any other illness or condition that the treating investigator feels would interfere with study compliance or would compromise the patient's safety or study endpoints
• Known history of severe uncorrectable reactions to iodinated and/or gadolinium-based contrast
• Angiographic Criteria: Patients with evident AV shunting, vascular disease or tortuosity precluding safe or feasible vascular access, or patient vasculature not conducive to delivery of the therapy on baseline imaging or angiography.

Egyéb
