SpaceOAR Post-Market Registry Study

Conditions studied: Prostate Cancer Patients Treated by Radiotherapy

In brief

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.
