Trial Design

2Treatment groups
Active Control
Group I: 25 Gy in 5 fractionsActive Control2 Interventions
Patients randomized to 25 Gy in 5 fractions will receive 150 mg/m^2 temozolomide per day for 5 days starting the first day of radiotherapy. This treatment will be followed by standard monthly 5 day cycles at 150 mg/m^2 for upto 1 year.
Group II: 40 Gy in 15 fractionsActive Control2 Interventions
Patients randomized to 40 Gy in 15 fractions will receive 75 mg/m^2 temozolomide per day for 15 days starting the first day of radiotherapy. This treatment will be followed by standard monthly 5 day cycles at 150 mg/m^2 for upto 1 year.

Frequently Asked Questions

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

Is this research pioneering in its methodology?

"In 2002, Schering-Plough initiated the first research trial for 25 Gy in 5 fractions. Subsequently, it was approved and granted Phase 2 drug approval after the 60 patient study concluded. Currently there are 207 active trials with 935 cities across 36 countries contributing to this large sample size."

Answered by AI

How is 25 Gy in 5 fractions typically administered to treat medical conditions?

"25 Gray administered in 5 separate treatments is a common way to manage nitrosourea treatment. Additionally, the same protocol can be used for various other cases including refractory neuroblastoma and advanced mycosis fungoides."

Answered by AI

Could you provide insight into prior investigations on 25 Gy in 5 fractions?

"At present, 207 clinical trials are underway searching for the efficacy of 25 Gy in 5 fractions. Of these studies, 24 are currently in phase 3 and mostly based around Seoul-Songpa; however, there is a total of 4752 sites that have operations related to this treatment running."

Answered by AI

How many participants is this trial accommodating?

"Affirmative. According to the information presented on clinicaltrials.gov, this medical trial is still recruiting participants having been initially posted in December 2021 and last updated in January 2022. 40 individuals are needed for testing at one site."
