Cognitive Outcomes After Brain Substructure-informed Radiation Planning in Pediatric Patients
NCT05658731
Recruiting
The goal of this trial is to determine whether it is possible to minimize radiation dose to parts of the brain that are important for thinking and learning in children who require radiation to treat their tumor, and if this will help reduce neurocognitive (thinking and learning) impairments in these patients. Patients with newly diagnosed brain or head and neck tumors who are having radiation therapy will have neurocognitive testing and MRI imaging (both research and for regular care) done as p...

A Study of ASP3082 in Adults With Advanced Solid Tumors
NCT05382559
Recruiting
This is an open-label study. This means that people in this study and clinic staff will know that they will receive ASP3082. The study aims to check how safe and well-tolerated ASP3082 is for people with advanced solid tumors that have a specific mutation called KRAS G12D. This study will be in 2 parts. In Part 1, different small groups of people will receive lower to higher doses of ASP3082 by itself, or together with cetuximab. Any medical problems will be recorded at each dose. This is done...

Subventricular Zone (SVZ) and Temozolomide in Glioblastoma Multiforme
NCT02177578
Recruiting
In this study patients will be treated with 6 weeks of radiation therapy plus temozolomide chemotherapy according to the standard of care. However, the radiation treatment plan will be modified to deliver an higher than routine radiation dose to the subventricular zone which is an area of the brain that contains stem cells that some scientists believe may contribute to glioblastoma recurrence. The purpose of the study is to see if the tumor is controlled for a longer period of time in patients t... Read More
