Trial Summary
What is the purpose of this trial?
To demonstrate the effectiveness of the SpaceOAR Vue System in reducing late gastrointestinal (GI) toxicity in subjects undergoing Stereotactic Body Radiotherapy (SBRT) to treat prostate cancer.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on anticoagulants (blood thinners), you may need to stop them for the procedure.
What data supports the effectiveness of the SpaceOAR Vue System treatment for prostate cancer?
Research shows that Stereotactic Body Radiotherapy (SBRT), a component of the treatment, is safe and effective for low- and intermediate-risk prostate cancer, with promising quality of life outcomes. Additionally, Stereotactic Ablative Radiotherapy (SABR) is feasible and well-tolerated for intermediate- and high-risk prostate cancer, although more data is needed for high-risk cases.12345
Is the SpaceOAR Vue System safe for use in humans?
How is the SpaceOAR Vue System with SBRT treatment for prostate cancer different from other treatments?
The SpaceOAR Vue System with SBRT is unique because it uses an iodinated rectal spacer to protect the rectum during radiation therapy, allowing for more precise targeting of the prostate cancer while minimizing damage to surrounding tissues. This approach is particularly beneficial for patients who cannot undergo MRI, as the spacer is visible on CT scans, aiding in accurate treatment planning.910111213

Stereotactic body radiotherapy with flattening filter-free beams for prostate cancer: assessment of patient-reported quality of life. [2021]Stereotactic body radiotherapy (SBRT) is an emerging treatment approach reported as safe and effective strategy for low- and intermediate-risk prostate cancer patients. End point of the current study is to appraise the patient-reported quality of life according to the expanded prostate cancer index composite (EPIC) questionnaire.
Stereotactic body radiation therapy for low and intermediate risk prostate cancer-Results from a multi-institutional clinical trial. [2022]We report the outcome of a phase I/II clinical trial of stereotactic body radiation therapy (SBRT) for low (LR) and select intermediate risk (IR) prostate cancer (PCa) patients.
Stereotactic Ablative Body Radiotherapy for Intermediate- or High-Risk Prostate Cancer. [2021]Stereotactic ablative radiotherapy (SABR) is a relatively novel form of high precision radiotherapy. For low- and intermediate risk patients, ultrahypofractionation (UHF - more than 5 Gy per day) has been compared to conventionally fractionated or moderately hypofractionated radiotherapy in two large randomized studies. A third smaller randomized study examined the question of the optimal frequency of treatments. The results of these studies will be reviewed. SABR for high risk prostate cancer has been shown to be feasible and is well tolerated with careful planning and setup techniques. However, there is currently insufficient data supporting its use for high-risk patients to offer SABR outside of a clinical trial. SABR costs less to the radiotherapydepartments and, the patient, as well as increasing system capacity. Therefore, it has the potential to be widely adopted in the next few years.
Dosimetric and patient correlates of quality of life after prostate stereotactic ablative radiotherapy. [2018]Initial results of Stereotactic Ablative Body Radiotherapy (SABR) in the treatment of localized prostate cancer appear promising however long-term quality of life (QOL) outcomes and dosimetric correlates are necessary.

Safety and Efficacy of Ultra-hypofractionation in Node-positive Prostate Cancer. [2021]The safety and efficacy of stereotactic body radiotherapy (SBRT) in localised prostate cancer are now established through phase III randomised trials. Its utility in node-positive prostate cancer is restricted due to a lack of controlled studies specifically addressing this subgroup. Herein we report the safety and efficacy of SBRT in this subgroup.
Stereotactic ablative radiotherapy with CyberKnife in the treatment of locally advanced prostate cancer: preliminary results. [2017]Recent clinical reports of stereotactic ablative radiotherapy (SABR) in the treatment of low-risk prostate cancer have been encouraging. Our study evaluates the efficacy and safety of SABR using the CyberKnife system for treating intermediate- to very-high-risk prostate cancer.
Prospective validation of stringent dose constraints for prostatic stereotactic radiation monotherapy: results of a single-arm phase II toxicity-oriented trial. [2022]There are no safety-focused trials on stereotactic body radiotherapy (SBRT) for localized prostate cancer. This prospective 3‑year phase II trial used binomial law to validate the safety and efficacy of SBRT with stringent organ at risk dose constraints that nevertheless permitted high planning target volume doses.
Utilization of Iodinated SpaceOAR Vue™ During Robotic Prostate Stereotactic Body Radiation Therapy (SBRT) to Identify the Rectal-Prostate Interface and Spare the Rectum: A Case Report. [2021]We describe the utilization of SpaceOAR Vue™, a new iodinated rectal spacer, during Robotic Stereotactic Body Radiation Therapy (SBRT) for a Prostate Cancer Patient with a contraindication to Magnetic Resonance Imaging. A 69-year-old Caucasian male presented with unfavorable intermediate risk prostate cancer and elected to undergo SBRT. His medical history was significant for atrial fibrillation on Rivaroxaban with a pacemaker. He was felt to be at increased risk of radiation proctitis following SBRT due to the inability to accurately contour the anterior rectal wall at the prostate apex without a treatment planning MRI and an increased risk of late rectal bleeding due to prescribed anticoagulants. In this case report, we discuss the technical aspects of appropriate placement and treatment planning for utilizing SpaceOAR Vue™ with Robotic SBRT.
Stereotactic body radiotherapy with periprostatic hydrogel spacer for localized prostate cancer: toxicity profile and early oncologic outcomes. [2020]Multiple phase I-II clinical trials have reported on the efficacy and safety of prostate stereotactic body radiotherapy (SBRT) for the treatment of prostate cancer. However, few have reported outcomes for prostate SBRT using periprostatic hydrogel spacer (SpaceOAR; Augmenix). Herein, we report safety and efficacy outcomes from our institutional prostate SBRT experience with SpaceOAR placement.

Case Report: Role of an Iodinated Rectal Hydrogel Spacer, SpaceOAR Vue™, in the Context of Low-Dose-Rate Prostate Brachytherapy, for Enhanced Post-Operative Contouring to Aid in Accurate Implant Evaluation and Dosimetry. [2022]We present a case series of 13 consecutive patients with prostate cancer treated with low-dose-rate (LDR) brachytherapy, utilizing SpaceOAR Vue™, the recent iodinated iteration of the SpaceOAR™ hydrogel rectal spacer. Low- and favorable intermediate-risk patients receiving monotherapy and unfavorable intermediate- and high-risk patients undergoing a brachytherapy boost were included. Permanent brachytherapy can result in subacute and late rectal toxicity, and precise contouring of the anterior rectal wall and posterior aspect of the prostate is essential for accurate dosimetry to confirm a safe implant. Clearly visible on non-contrast CT imaging, SpaceOAR Vue™ can substantially aid in post-implant contouring and analysis. Not previously described in the literature in the context of LDR brachytherapy, we demonstrate the added clinical benefit of placing a well-visualized rectal spacer.
