RAPPLE Trial Summary

This trial is testing a new, more targeted form of radiation therapy against the standard form of radiation therapy to see if it is just as effective in treating brain metastases.

Who is the study for?
This trial is for adults with non-blood related cancers that have spread to the brain. Participants should have multiple brain tumors that can be targeted, a life expectancy not suitable for surgery or precise radiotherapy, and some active cancer outside the brain. They must also be able to complete questionnaires, follow up with imaging tests, start treatment within two weeks of joining, and have a performance score indicating they are still somewhat active.Check my eligibility
What is being tested?
The study is testing if one session of targeted radiation (8 Gy) is as effective as five sessions (20 Gy total) in extending overall survival for patients with poor prognosis due to brain metastases from other cancers. The goal is to determine whether this simpler and quicker treatment approach works just as well.See study design
What are the potential side effects?
While specific side effects aren't listed here, radiation therapy can generally cause fatigue, headaches, hair loss at the treated site, nausea, and may temporarily worsen neurological symptoms related to brain tumors.

Group I: 8 Gy in 1 Fraction Volumetric Modulated Arc Therapy to Brain MetastasesExperimental Treatment1 Intervention
A single treatment of 8 Gy will be delivered using volumetric modulated arc therapy on a conventional linear accelerator in a conventional head shell without the use of stereotactic radiosurgery technique.
Group II: 20 Gy in 5 Fractions Volumetric Modulated Arc Therapy to Brain MetastasesActive Control1 Intervention
Five treatments of 4 Gy will be delivered using volumetric modulated arc therapy on a conventional linear accelerator in a conventional head shell without the use of stereotactic radiosurgery technique.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What health risks have been identified with Targeting All Brain Metastases?

"Our experts at Power have judged the safety of Targeting All Brain Metastases to be a 2, due to this being a Phase 2 trial. This implies that there is data in support of its security, yet no proof that it actually works as intended."

Answered by AI

How many participants can join this examination?

"Affirmative. According to clinicaltrials.gov, this medical experiment is presently enlisting patients who meet the eligibility criteria. It was first advertised on July 1st 2022 and updated as recently as October 1 of the same year; it aims to recruit 100 participants from a single site."

Answered by AI

To what demographic is this research opportunity available?

"Patient recruitment for this trial is seeking to enrol 100 individuals, aged 18 or above and below the age of 65, who have been diagnosed with neoplasm metastasis. Additionally, those accepted must possess a DS-GPA ≤ 2.0; brain tumours that can be contoured and targeted; an expected median survival time too short for surgery/stereotactic radiosurgery; a willingness to partake in regular imaging follow up sessions; as well as any size of extracranial disease."

Answered by AI

Is the age qualification for this trial less than seventy-five years old?

"According to the study's eligibility requirements, the minimum age for participation is 18 and seniors up to 100 years old are able to join."

Answered by AI

Are there any opportunities for volunteers to join this research project?

"Affirmative. The clinical trial's entry on clinicialtrials.gov reveals that the study, which was initially posted on July 1st 2022, is actively recruiting volunteers. There are one hundred participants needed from a single research centre to complete this investigation."
