About this trial

Recently, concerns have been raised by regulators that there is little data about the long-term safety of rectal hydrogel spacers for use in conjunction with radiotherapy treatment for prostate cancer. To address this, this study will collect data about the short-term side-effects and long-term safety of SpaceOAR and SpaceOAR Vue rectal hydrogel spacers in men who receive them in the UK and France. Men who have agreed to receive these spacers as part of their standard medical care will be asked to take part in the study whereby data about their treatment and health will be collected from their medical records and from members of the clinical team who deliver their treatment. Additionally, men will be asked to consent to completing questionnaires about their experiences of side effects from their treatment. Further information will be collected about their clinical characteristics before they receive a spacer, the physician-rated clinical performance of the spacer insertion procedure, their radiotherapy treatment plan and details of the other treatments they are also receiving which could influence the types and extent of side effects they experience. Data collection will span eight time points: pre-spacer insertion, spacer insertion, the start of radiotherapy, post-radiotherapy follow-up, 6-month follow-up, 12-month follow-up, 24-month follow-up \& 36-month follow-ups. Outside of these timepoints treatment-related adverse event data will be concurrently reported and collated. Participants' treatments will not be changed as a result of their participation in this study. Data from this study will be used to summarise the characteristics of this study population, physicians' perceptions of the spacer implantation procedure, the radiotherapy treatments plans made, and the types, extent and timing of treatment-related adverse events and side effects.

Treatments tested in this trial

  • SpaceOAR / SpaceOAR Vue hydrogel system

    Device

    Space OAR/SpaceOAR Vue Systems are biodegradable medical devices that are implanted between the prostate and rectum to temporarily move part of the rectal wall away from the prostate during radiation therapy for prostate cancer.

Trial outcomes

Primary outcomes

1

Short-term safety of SpaceOAR/SpaceOAR Vue systems.

Proportion of subjects experiencing any of the following within 30 days post-implantation of SpaceOAR/SpaceOAR Vue hydrogel, as adjudicated by the Independent Clinical Events Committee: * Symptoms (PROMs): Measured using validated patient-reported outcome questionnaires. A subject is counted if any PROM score exceeds the predefined threshold for clinically significant symptoms. * Adverse Events (CTCAE v5.0): Measured as the occurrence of any adverse event graded per CTCAE v5.0. * Abnormal Imaging (MRI/CT): A subject is counted if any abnormality is confirmed by radiology review. \* The study instruments in the French population with include Grade 1 and above events (CTCAEv5.0) * Unit of Measure: Percentage of subjects (%) * Each category will be reported separately.

Time frame
30 days post-implantation
2

Long-Term Safety of SpaceOAR/SpaceOAR Vue Systems

Proportion of subjects experiencing Grade ≥2 gastrointestinal or anorectal toxicity (per CTCAE v5.0) within 3 years after completion of radiation therapy. \* The study instruments in the French population with include Grade 1 and above events (CTCAEv5.0) • Unit of Measure: Percentage of subjects (%)

Time frame
Up to 3 years post-radiation therapy

Secondary outcomes

1

Proportion of subjects with Grade 2* & above; gastrointestinal, anorectal, genitourinary toxicity at 12, 24 & 36 months.

Proportion of subjects experiencing Grade ≥2 toxicity (as per CTCAE v5.0) in gastrointestinal, anorectal, or genitourinary systems at 12, 24, and 36 months post-radiation therapy. • Unit of Measure: Percentage of subjects (%) Note: For French population, Grade ≥1 events will also be included.

Time frame
12, 24, and 36 months post-radiation therapy
2

Physician rating of SpaceOAR/SpaceOAR Vue of Placement Difficulty

Rated on a Likert scale (1 = very difficult, 5 = very easy) immediately after procedure. Unit of Measure: Mean Likert score

Time frame
At time of implantation
3

Patient Perception of SpaceOAR/SpaceOAR Vue Procedure Compared to Prostate Biopsy

Measured using a structured questionnaire comparing perceived discomfort and acceptability relative to prostate biopsy. • Unit of Measure: Percentage of subjects reporting "less discomfort," "similar," or "more discomfort

Time frame
Within 30 days post-procedure
4

Overall Mortality and Cause of Death

Number and proportion of subjects who die during the study period, with cause adjudicated by Independent Clinical Events Committee. • Unit of Measure: Number of deaths and percentage (%)

Time frame
Up to 36 months
