About this study

Official title: Pilot: Impact of High-Dose, Single Fraction Radiation on Immunogenicity of Sipuleucel-T in Metastatic Castration Recurrent Prostate Cancer Patients

This pilot clinical trial studies the impact of radiation therapy on the immunogenicity of Sipuleucel-T. Patients with castration recurrent prostate cancer who are eligible for treatment with Sipuleucel-T and who have bone metastases are eligible.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess whether radiation therapy (RT) increases the immunogenic potential or sipuleucel-T in participants with castration recurrent prostate cancer.

II. To assess systemic changes to the immune system and genetic changes to immune cells in participants treated by the combination of RT and sipuleucel-T.

III. To assess the induction of antigen-specific immune responses to prostatic acid phosphatase (PAP), cancer/testis antigen 1B (NY-ESO-1) and antigens that have proven to be released by radiation (such as, heat shock protein 90 [HSP-90], calreticulin, etc.).

SECONDARY OBJECTIVES:

  1. To assess adverse event rates in participants receiving the high-dose radiation and sipuleucel-T therapy.

II. To assess prostate-specific antigen (PSA) changes. III. To assess overall and cancer specific survival.

OUTLINE:

Patients undergo single-fraction radiation therapy to at least 1 bone lesion 2 days after the first sipuleucel-T dose.

After completion of study treatment, patients are followed up at 3 and 6 months and then annually thereafter.

What is being measured

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

  1. Capacity of T cells to proliferate in response to antigen stimulation, assessed with a tritiated thymidine incorporation assay and an interferon-gamma enzyme-linked immunosorbent spot assay

    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.

    Measured: Up to 6 months

  2. Change in antigen-specific humoral response measured via enzyme-linked immunosorbent assay

    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.

    Measured: Baseline up to 6 months

  3. Change in the genetics of immune effectors, measured with ribonucleic acid from monocytic and lymphocytic cells

    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.

    Measured: Baseline to 6 months

  4. Quantification of lymphocyte subsets and NK cells

    Will be assessed using Wilcoxon Signed Rank and McNemar's tests for continuous and dichotomous endpoints respectively.

    Measured: Baseline to 6 months

Secondary outcomes (4)
  1. Adverse event rates assessed using National Cancer Institute Common Terminology Criteria for Adverse Events version 4

    The Clopper-Pearson one-sided upper 95% confidence limit will be provided. Associations between baseline characteristics and presence of an adverse event will be considered using the Wilcoxon rank sum test (or Cochran-Armitage test for trend) and Fisher's exact test respectively. Bar charts, scatterplots and other descriptive and graphical methods will also be utilized.

    Measured: Up to 6 months

  2. Cancer-specific survival

    Will be depicted using Kaplan Meier methods.

    Measured: Up to 2 years

  3. Change in PSA

    Measured: Baseline up to 6 months

  4. Overall survival

    Will be depicted using Kaplan Meier methods.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Laboratory Biomarker Analysis and Radiation Therapy in people with Hormone-Resistant Prostate Cancer and Metastatic Malignant Neoplasm in the Bone, run by Roswell Park Cancer Institute at 2 sites 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 5 inclusion and 6 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 5 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Capacity of T cells to proliferate in response to antigen stimulation, assessed with a tritiated thymidine incorporation assay and an interferon-gamma enzyme-linked immunosorbent spot assay (time frame: Up to 6 months). The study lists 4 primary outcomes in all. 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 5 Aug 2021.
