Trial summary

This phase I trial studies the side effects and best dose of stereotactic body radiation therapy in treating patients with prostate cancer after undergoing surgery. Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 19 years and older
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • History of diagnosis of prostate cancer after undergoing prostatectomy
  • No evidence of regional nodal or distant metastases based on computed tomography (CT) abdomen and pelvis and whole body bone scan within 120 days prior to study entry; nodes less than 1.5 cm will be considered reactive and biopsy is not required; nodes 1.5 cm or larger are required to undergo biopsy and be negative prior to study registration; bone scan findings in the absence of blastic or lytic lesion correlates on CT imaging will also be deemed non-neoplastic
  • Eastern Cooperative Oncology Group (ECOG) performance scale 0-2
  • Child bearing potential: In this patient population, this pertains to the ability to conceive a child; eligible patients already have received prostatectomy, and therefore this risk is not applicable
  • Prostate specific antigen (PSA) value can be undetectable up to a value of 2.0 within 30 days prior to study entry
  • PSA value that is undetectable can be enrolled if pathology from prostatectomy demonstrates one or more of the following: positive margin, extracapsular extension, or seminal vesicle invasion
  • All subjects must have the ability to understand and the willingness to sign a written informed consent

Who cannot join

  • Patients should not have any uncontrolled illness including ongoing or active infection
  • Patients may not be receiving any other investigational agents, or concurrent biological chemotherapy
  • Patients with history of prior malignancies (with exception to non-melanoma skin cancer) are ineligible for this study, unless they are documented to be disease-free for at least 5 years
  • Study-specific exclusions:
  • History of prior radiation to the pelvis
  • History of uncontrolled inflammatory bowel disease
  • Unable to comply with radiation therapy procedures
  • Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study

About this study

Official title: Stereotactic Body Radiation Therapy to the Prostate Fossa: Phase I Dose Escalation Study

This phase I trial studies the side effects and best dose of stereotactic body radiation therapy in treating patients with prostate cancer after undergoing surgery. Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the maximum tolerated dose (MTD) with an upper limit of 45 Gray (Gy) in 5 fractions, in the delivery of stereotactic body radiation therapy (SBRT) to the prostate fossa.

SECONDARY OBJECTIVES:

  1. To assess acute and late toxicities from treatment.

II. To assess biochemical progression-free survival.

III. To collect prospective quality-of-life data related to bowel, urinary, and sexual health.

OUTLINE: This is a dose-escalation study.

Patients receive 5 fractions of SBRT over 1.5 weeks.

After completion of study treatment, patients are followed up at 90 days and then periodically for 3 years.

Being tested
stereotactic body radiation therapy, quality-of-life assessment, laboratory biomarker analysis

What is being measured

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

  1. MTD, defined as the highest dose tested in which fewer than 33% of patients experienced dose limiting toxicity, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    Tables will be created to summarize these toxicities and side effects by dose level.

    Measured: 90 days

Secondary outcomes (4)
  1. Incidence of acute toxicities observed at each dose level graded according to the NCI CTCAE version 4.0

    Tables will be created to summarize these toxicities and side effects by dose level.

    Measured: Up to 90 days

  2. Incidence of late toxicities observed at each dose level graded according to the NCI CTCAE version 4.0

    Tables will be created to summarize these toxicities and side effects by dose level.

    Measured: Up to 3 years

  3. Biochemical progression-free survival

    Estimated using Kaplan-Meier. 95% confidence intervals should be provided.

    Measured: Up to 3 years

  4. Prospective quality-of-life data related to bowel, urinary, and sexual health using the numerical scores generated from the patient questionnaires

    Quality of life questionnaires include the International Prostate Symptom Scale (IPSS), sexual health inventory for men (SHIM), and Merrick rectal function scale.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing stereotactic body radiation therapy, quality-of-life assessment and laboratory biomarker analysis in people with Recurrent Prostate Cancer and Stage I Prostate Cancer, run by City of Hope Medical Center 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 7 inclusion and 8 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: under way, not looking for participants, as of the sponsor's last update on 1 Sep 2026. 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 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.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

MTD, defined as the highest dose tested in which fewer than 33% of patients experienced dose limiting toxicity, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Sep 2026.
