About this study

Official title: Phase I/II Trial Examining Dose-per-Fraction Escalation Using Intensity Modulated Radiation Therapy in the Treatment of Prostate Cancer

The purpose of this study is to examine the clinical feasibility of using Intensity-modulated radiation therapy (IMRT) combined with daily pretreatment prostate localization to deliver increasingly hypofractionated treatment courses. Progressively larger fraction sizes will be delivered in a phase I design based on both acute and long-term tolerances to the treatment. The dose-per-fraction escalation design utilizes schemas that maintain an isoeffective dose for late effects, while predicting that tumor control will actually improve. The delivery of fewer, larger fractions of radiation, if proven effective and safe, would result in significant cost saving and more efficient use of resources. Phase II will commence with Maximum Tolerated Dose (MTD) finding with up to 200 additional patients being enrolled during this phase of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Experience Grade 3 or Higher Acute Toxicities

    To evaluate acute tolerances to dose-per-fraction escalation in the treatment of prostate cancer using optimized treatment of Intensity-modulated radiation therapy (IMRT), daily rectal balloon displacement, and transabdominal ultrasound localization of the prostate. For toxicities observed within the first 10 patients at each hypofractionation level, ≥20% acute grade 3 or higher GI or genitourinary (GU) toxicity will constitute a threshold toxicity level and will dictate a decrease in frequency of treatment by one treatment per week. Maximum tolerated dose is reached if 20% of participants experience acute toxicities grade 3 or higher.

    Measured: 90 days post radiation treatment

  2. Number of Subjects Experiencing Grade 2 or Higher Late Rectal Toxicities at Any Time During Follow Up

    To evaluate late radiation toxicities to dose-per fraction escalation in the treatment of prostate

    Measured: from 90 days post XRT through last follow-up visit (up to 3 years)

Secondary outcomes (5)
  1. Biochemical Progression-free Survival Based on PSA Surveillance

    Patients will be considered to be without biochemical recurrence if either the Prostate-specific antigen (PSA) is still declining or the PSA nadir has been reached and is below 1.0ng/ml

    Measured: up to 15 years from enrollment

  2. Fox Chase Bowel Survey at Baseline and 3 Years

    The Fox Chase Bowel/Bladder survey was divided into two sections: Bowel (questions 1 to 14, N=14) and Bladder (questions 19, and 21 to 30, N=11). To facilitate analysis, Bowel and Bladder scores for each section were rescaled to a total score of between 0 - 100, where higher scores indicated better Quality of Life (QoL). Results for the Bowel Section are reported here.

    Measured: Baseline and 3 years

  3. Fox Chase Bladder Survey at Baseline and 3 Years

    The Fox Chase Bowel/Bladder survey was divided into two sections: Bowel (questions 1 to 14, N=14) and Bladder (questions 19, and 21 to 30, N=11). To facilitate analysis, Bowel and Bladder scores for each section were rescaled to a total score of between 0 - 100, where higher scores indicated better Quality of Life. Results for the Bladder Section are reported here.

    Measured: Baseline and 3 years

  4. International Index of Erectile Function (IIEF) Score at Baseline and 3 Years

    The IIEF is a 15-item survey where 9-items are scored 0-5 and 6-items are scored 1-5 with a total range of 6-75. The standard scoring mechanism was used for IIEF, where the QoL items corresponded to the following domains: erectile function (score range 1-30), orgasmic function (score range 1-10), sexual desire (score range 2-10), intercourse satisfaction (score range 0-15), and overall satisfaction (score range 2-10). Higher numbers indicate increased QoL.

    Measured: Baseline and 3 years

  5. Spritzer Quality of Life Index (SQLI) at Baseline and 3 Years

    The SQLI is composed of five items (activity, daily living, health, support, outlook) scored utilizing a numerical scale of 0-2. Standard scoring was also used for the SQLI survey (total score range 0-10) where higher score indicate increased QoL.

    Measured: Baseline and 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Radiotherapy in people with Prostate Cancer, run by University of Wisconsin, Madison at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Who Experience Grade 3 or Higher Acute Toxicities (time frame: 90 days post radiation treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00214097, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Nov 2019.
