Evaluation of the Efficacy and the Safety of a Stereotaxic Prostatic Radiotherapy Delivered With Linac MRI, in Patients With Prostate Adenocarcinoma (STEREO-RML)

February 12, 2024 updated by: Centre Georges Francois Leclerc

Multicenter Phase II Study Evaluating the Efficacy and Safety of a Stereotaxic Prostatic Radiotherapy Delivered on Linac MRI, With Integrated Boost in the Case of an Index Tumor, in Patients With Prostate Adenocarcinoma of Favorable, Intermediate or Risky Risk. High Risk Very Localized.

Stereotaxic prostatic radiotherapy on Linac MRI, with monitoring of movements of the pelvic organs per fraction on the prostate in real time, in 4 sessions, with integrated boost on the index tumor (if it is visible on the diagnostic MRI), could reduce the digestive, urinary and sexual toxicities accumulated at 5 years and guarantee excellent local tumor control, for patients with localized prostate cancer, with a favorable prognosis, intermediate or very local high risk, according to the D'Amico classification.

The benefits that patients participating in this research could obtain are:

  • Better disease control efficiency
  • A reduction in the duration of treatment to 4 radiotherapy sessions (2 weeks maximum) instead of 40 sessions (8 weeks) for usual treatment.
  • Avoid the risks associated with the implantation of prostate markers necessary for stereotaxic radiotherapy on a standard accelerator (anesthetic risks, infectious risks, hemorrhagic risks, pain risks)
  • Better quality of life

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
