Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients who are eligible for this trial will consent to Radiation Therapy and the insertion of TraceIT hydrogel injection.
This appointment will involve both the Radiation Oncologist and the Urologist. A probe will be placed in your rectum and a numbing solution will be injected in the region between the anus and the genitals (known as the “perineum”). 10mL of the TraceIT® gel material will be introduced into the perineum using a long fine needle. The needle placement and injection will be guided by use of sound waves from the rectal probe, which is used to create a picture of the pelvic organs as the needle is advanced and the spacer material is deposited between the prostate and the rectum. Following injection, the needle and probe will be removed
An MRI and planning CT is performed 3-5 days post procedure.
Treatment planning and radiotherapy are delivered per departmental standards and include image guidance during radiation therapy, weekly review during treatment and regular follow-up post treatment.
The resorption of the gel will be assessed using MRI scans at the planning stage, 3 and 12 months post treatment.

Outcomes
Primary outcome [1] 306051 0
The primary outcome of this study is to evaluate the efficacy of the TraceIT product. This will be assessed by evaluating the space created between the prostate and anterior rectal wall through the use of an MRI at 3 different time points. In each of these scans, we will assess the changes in visibility, in combination with, the resorption of the hydrogel over time.
Timepoint [1] 306051 0
MRIs will be taken at baseline, 3 months and 12 months post radiation therapy.
Secondary outcome [1] 347438 0
Treatment toxicity based on RTOG/EORTC Late Radiation Morbidity Scoring Schema
Timepoint [1] 347438 0
Up to and including 12 months post Radiation Therapy
Secondary outcome [2] 347439 0
Patient reported outcomes using the Expanded Prostate Cancer Index Composite (EPIC) Quality of Life Questionnaire
Timepoint [2] 347439 0
Questionnaires are provided at baseline, end of treatment, 3 months and 12 months

Safety/efficacy
Statistical methods / analysis
Comparisons will be made between our SpaceOAR historical cohort and TraceIT population, evaluating the space created between the prostate and anterior rectal wall and the rectal doses using either paired T-test or Wilcoxon signed-rank test depending on if the distribution assumption is violated. We do not expect any difference in space created between the prostate and anterior rectal wall or dose received by the rectum between the two cohorts.
If this is a true effect then with 10 patients we have estimated a power between 0.95 and 1.00 to detect no difference. The table below shows the expected % rectal dose with SpaceOAR (calculated from 76 historical controls treated to 78Gy with same technique and submitted for publication) and the hypothesised dose with the use of TraceIT.
