A Study Of Lutetium Lu 177 Dotatate (Lutathera®) In Patients With Inoperable, Progressive Meningioma After External Beam Radiation Therapy Rochester, Minn. 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. Study Of RYZ401 In Subjects With Solid Tumors Expressing SSTRs. Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz. The primary objectives are to determine the recommended Phase 2 dose (RP2D) and optimal treatment regimen, characterize safety and tolerability, and evaluate preliminary efficacy of RYZ401 in subjects with NETs and other selected solid tumors expressing SSTRs. A Registry For Children Treated With Proton Radiation Therapy Rochester, Minn. The purpose of the Pediatric Proton Consortium Registry (PPCR) is to enroll children who have been treated with proton radiation in the United States in order to describe the population that currently receives protons and better evaluate its benefits over other therapies. The data collected from this study will help facilitate research on proton beam radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data which many centers that deliver proton radiation therapy already collect in routine operations. A Study Of CGM In GBM Rochester, Minn., Scottsdale/Phoenix, Ariz., Jacksonville, Fla. The purpose of this study is to compare standard glucose monitoring versus continuous glucose monitoring (CGM) with endocrinology-guided intervention in newly diagnosed glioblastoma (GBM) patients receiving standard-of-care therapy. A Feasibility Study To Evaluate The Safety Of The TheraSphere Glioblastoma (GBM) Device In Patients With Recurrent GBM Jacksonville, Fla. The purpose of this study is to assess the safety and technical feasibility of TheraSphere GBM in patients with recurrent glioblastoma (GBM). EF-41/KEYNOTE D58: Phase 3 Study Of Optune Concomitant With Temozolomide Plus Pembrolizumab In Newly Diagnosed Glioblastoma Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz. This is a multicenter, two-arm, randomized, double-blind, placebo-controlled study of Optune® (Tumor Treating Fields at 200 kHz) together with maintenance Temozolomide (TMZ) chemotherapy agent and pembrolizumab compared to Optune® together with maintenance TMZ and placebo in newly diagnosed Glioblastoma (GBM) patients.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
