Barrigel® PPRT (Post-Prostatektomi strålebehandling) prøve
Randomisert utprøving av Barrigel® for å øke avstanden mellom rektum og prostataseng for å redusere rektal dose hos pasienter som får moderat hypofraksjonert strålebehandling og som har hatt tilbakefall av prostatakreft etter prostatektomi
Barrigel is intended to temporarily position the anterior rectal wall away from the prostate or prostate bed during radiotherapy treatment for prostate cancer and, in creating this space, it is the intent of Barrigel to reduce the radiation dose delivered to the anterior rectum.

Detaljert beskrivelse
Barrigel is composed of biodegradable material and maintains space for the entire course of prostate or prostate bed radiotherapy and is intended to be absorbed by the patient's body over time.
To evaluate the safety and effectiveness of Barrigel to reduce the radiation dose delivered to the anterior rectum by creating a space when injected between the rectum and the prostate bed in men receiving definitive external beam radiation therapy (intensity-modulated radiation therapy) for recurrence of prostate cancer after radical prostatectomy.
A prospective, randomized, controlled, single-masked multicenter study.

Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Treatment Arms
Subjects will be injected Barrigel between the rectum and prostate bed using transrectal ultrasound for guidance. |
Barrigel is an absorbable gel based on Non-Animal Stabilized Hyaluronic Acid (NASHA™) that is injected into the peri-rectal space All subjects will have a transrectal ultrasound (TRUS) conducted. In the control subjects this will act as a sham procedure. For the investigational subjects, the TRUS will be used to visualize the placement of the needle |
|
Sham-komparator: Control Arm
Subjects randomized to the control group will not receive Barrigel but will have a Transrectal ultrasound probe inserted to simulate that aspect of the injection of Barrigel. |
All subjects will have a transrectal ultrasound (TRUS) conducted. In the control subjects this will act as a sham procedure. For the investigational subjects, the TRUS will be used to visualize the placement of the needle |
