The SPARC Trial: Stereotactic Prostate Ablative Radiotherapy Using Cyberknife (SPARC)

May 20, 2014 updated by: Royal Marsden NHS Foundation Trust

Stereotactic Prostate Augmented Radiotherapy With Cyberknife

Giving a higher dose of radiation to the dominant tumour nodule within the prostate is hypothesized to improve tumour control. This trial will assess whether this technique, delivered in 5 treatments, can be delivered without increasing side effects.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Aim To assess if a focal boost can be delivered to the dominant tumour nodule alongside 36.25 Gy in 5 fractions to the whole prostate gland.

Primary end-point: Acute toxicity (Radiation Therapy Oncology Group (RTOG), International prostate symptom score (IPSS))

Secondary end-points: Prostate specific antigen (PSA) nadir and 2-year biochemical control Late toxicity (IPSS, RTOG, International index of erectile function (IIEF-5)) Quality of life (EQ5D scale)

Inclusion criteria

  • Prostate cancer patients with any of the following:
  • PSA>20
  • Gleason grade 4+3 or higher
  • Stage T3a
  • Exclusion criteria
  • Nodal or metastatic disease
  • PSA>40
  • Stage T3b or higher

Study interventions

This is a phase II study which will recruit 20 patients. A dose of 36.25 Gy in 5 fractions will be delivered to the whole prostate with a simultaneous integrated boost up to 47.5 Gy in 5 fractions or to the highest dose possible within dose constraints. The boost volume will be defined on the multiparametric magnetic resonance scan by the specialist radiologist.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Acute genitourinary(GU) toxicity
Time Frame: Maximal recorded toxicity within the acute toxicity period (up to 12 weeks)
RTOG scale acute GU toxicity will be measured at baseline, end of treatment, then 2,4 and 12 weeks post treatment. The maximal toxicity during follow up is the primary outcome measure.
Maximal recorded toxicity within the acute toxicity period (up to 12 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Acute gastrointestinal (GI) toxicity
Time Frame: Within 12 weeks of treatment completion
RTOG scale
Within 12 weeks of treatment completion
Late GI and GU toxicity
Time Frame: From 12 weeks until study completion
RTOG scale
From 12 weeks until study completion
Patient reported outcomes i.e. IPSS, IIEF-5 and EQ5-D

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
