Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes
Primary outcome [1] 0 0

Timepoint [1] 0 0
up to 36 months
Secondary outcome [1] 0 0
Patient treatment outcomes determined by assessing Biochemical-clinical failure (BCF)
Timepoint [1] 0 0
up to a maximum of 36 months.
Secondary outcome [2] 0 0
Patient treatment outcomes determined by assessing acute and late toxicity grade 3 or higher (using CTCAE version 4)
Timepoint [2] 0 0
Weekly during treatment, then two weeks, six weeks and 6 months post treatment
Secondary outcome [3] 0 0
Patient treatment outcomes determined by assessing patient-reported outcomes
Timepoint [3] 0 0
12 and 24 months after treatment
Secondary outcome [4] 0 0
The patient's perception of KIM will be quantified using an adapted SAT-RAR survey, an instrument that has previously been used to assess patient perceptions on technological innovations in radiotherapy and respiratory gating.
Timepoint [4] 0 0
up to 36 months
Secondary outcome [5] 0 0
Targeting accuracy through measuring the final geometric accuracy with and without the KIM gating procedure
Timepoint [5] 0 0
up to 36 months

Summary
Brief summary
The SPARK trial is testing the use of Kilovoltage Intrafraction Monitoring in prostate cancer patients being treated with Stereotactic Prostate Adaptive Radiotherapy. The researchers expect this trial to result in better targeted prostate cancer patient outcomes with lower toxicity. The potential application of Kilovoltage Intrafraction Monitoring to other tumour sites will pave the way for additional trials with Australasian radiation oncology leading the world.
