Early Assessment of Treatment Response Using Functional Diffusion Mapping

December 8, 2014 updated by: University of Michigan Rogel Cancer Center
This study will evaluate the feasibility of identifying changes in diffusion MRI characteristics of bone that correlates with response to therapy in men with metastatic prostate cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This study will evaluate a special type of MRI (magnetic resonance imaging) scan that measures the movement of water molecules through tissue called diffusion MRI. Researchers are using this new MRI technology to track the diffusion, or movement, of water through tumor tissue, and map these changes as a cancer patient undergoes treatment. Early research seems to indicate that tumor cells restrict the movement of water, so as tumor cells die, the movement of water changes within the tumor. These changes in the movement (diffusion) of water may help doctors determine earlier than traditional tests whether a patient's cancer is responding (getting better) to treatment. This study will evaluate the feasibility of identifying changes in diffusion MRI characteristics of bone that correlates with response to therapy in men with metastatic prostate cancer.

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

  • ADULT
  • OLDER_ADULT
  • CHILD

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: Diffusion MRI Assessment
Men with newly diagnosed metastatic disease initiating therapy with androgen deprivation, or men with hormone refractory prostate cancer initiating treatment with chemotherapy, will be assessed by diffusion MRI (Magnetic Resonance Imaging) at baseline, 2 weeks and again at 9-12 weeks.
Procedure: Diffusion MRI

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
Change in diffusion MRI measurements
Time Frame: Baseline, 2 weeks and 9-12 weeks
Identify changes in Diffusion Magnetic Resonance Imaging (MRI) measurements and correlate the changes with response to therapy.
Baseline, 2 weeks and 9-12 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
Change in units/L of CK18Asp306
Time Frame: Baseline, 2 weeks and 9-12 weeks
Levels of CK18Asp396 can be measured in serum using a commercially available ELISA (Enzyme-linked Immunosorbent Assay). Changes in serum CK18Asp396 (a marker of apoptosis) will be correlated with functional diffusion maps and treatment response.
Baseline, 2 weeks and 9-12 weeks
Change in levels of bone turnover markers
Time Frame: Baseline, 2 weeks and 9-12 weeks
Correlate the changes in biochemical markers of bone turnover, such as N-telopeptide and bone-specific alkaline phosphatase, with functional diffusion maps and treatment response.
Baseline, 2 weeks and 9-12 weeks
