SpaceOAR System RWS in China
Study Details
Study Description
Brief Summary
This study aims to evaluate the safety and performance of SpaceOAR System when it is used to create space between the rectum and prostate in men undergoing radiotherapy for localized T1-T2 prostate cancer in China via collecting the real word data of SpaceOAR System used, to generate local clinical evidence on Chinese patients.

Detailed Description
This study is a retrospective and prospective, single arm, real world study. For those patients who have already received the SpaceOAR treatment before study kick-off, the data at baseline and the day of procedure will be retrospectively collected. For those patients who will receive SpaceOAR treatment after study kick-off, the clinical data at baseline, the day of procedure and 30 days post procedure will be prospectively collected.
Up to 20 subjects with a pathologically confirmed diagnosis of clinical stage T1 or T2 prostate cancer indicated for radiotherapy will be enrolled, for there are chances of missing data in the real world study. A sample of 14 subjects provides at least 90% power for the primary objective.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: SpaceOAR Treatment Arm Single arm, up to 20 subjects with a pathologically confirmed diagnosis of clinical stage T1 or T2 prostate cancer indicated for radiotherapy will be enrolled, for there are chances of missing data in the real world study. A sample of 14 subjects provides at least 90% power for the primary objective. |
Device: SpaceOAR Treatment
SpaceOAR System is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of SpaceOAR System to reduce the radiation dose delivered to the anterior rectum.
The SpaceOAR System is composed of biodegradable material and maintains space for the entire course of prostate radiotherapy treatment and is completely absorbed by the patient's body over time.

Outcome Measures
Primary Outcome Measures
- Primary Effectiveness Endpoint [Within 10 days post spaceOAR hydrogel administration.]
The distance between the posterior prostatic capsule and anterior rectal wall post SpaceOAR hydrogel administration. Measurement: The distance between the posterior prostatic capsule and anterior rectal wall is measured on the axial image slice closest to halfway between apex and base, from posterior edge of prostate to inner rectal wall via MRI.
- Primary Safety Endpoint [Within 30 days following procedure]
AEs related to SpaceOAR system and/or procedure within 30 days following procedure will be observed.
Secondary Outcome Measures
- Functional Success [Within 10 days post spaceOAR hydrogel administration.]
Defined as creation of at least 7.5mm space between the posterior prostatic capsule and anterior rectum wall as assessed via comparative pre and post SpaceOAR hydrogel injection MRI scans.
