NTS-WBRT in Brain Metastases

Официальное название

Phase II Trial of Normal Tissue Sparing Whole Brain Radiation Therapy (NTS-WBRT) in Patients With Brain Metastases

Обзор

This research is being done to assess the quality of life and symptom burden in participants who receive (normal tissue sparing whole brain radiation therapy (NTS-WBRT). This research study involves: * NTS-WBRT (normal tissue sparing whole brain radiation therapy) * Memantine standard of care drug

Подробное описание

This is a Phase 2 trial testing the safety and effectiveness of NTS-WBRT (normal tissue sparing whole brain radiation therapy) in treating brain metastases.

NTS-WBRT is a targeted radiation therapy that further reduces radiation dose to tissue that does not need radiation therapy treatment.

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.

It is expected that about 41 people will take part in this research study.

• Prior whole brain radiation therapy
• Pre-existing or current use of memantine or other NMDA antagonists
• Known allergy to contrast used in imaging studies and/or inability to have MRI imaging
