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 is a single-arm observational longitudinal study in of patients with metastatic castrate-resistant prostate cancer designed to assess the longitudinal trajectory of pain and other symptoms. The study aims to address several key methodological questions that will inform the design of future clinical trials with symptom endpoints in this population, including: the definition of "clinically meaningful" pain; criteria for concluding a clinically meaningful pain reduction; criteria for concluding clinically meaningful pain progression; reliable methods quantifying analgesic use (given that "equianalgesic tables" and "point scoring systems" are generally considered unreliable by pain researchers and regulatory agencies , , ); ideal recall periods for pain questions; tradeoffs of different frequencies of symptom reporting; symptom trajectories over time; and associations of pain scores with other metrics used in prostate cancer research (imaging, PSA values, circulating tumor cells, etc).

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

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Single Arm
Surveys, diaries, clinical assessments of men with metastatic castrate-resistant prostate cancer
Behavioral: Survey
Patients will report pain and analgesic use through the automated telephone system, for 7 days in a row, once every 6 weeks. Data from diagnostic tests (CT Abdomen/Pelvis, Bone Scan, PSA, and circulating tumor cells) conducted during the study period will be collected from medical records by local personnel and entered into the secure online database quarterly, but no specific tests or schedules will be required in this observational study. Patients will remain on study for up to 26 months (slightly longer than the expected median survival in this population based on data from docetaxel, abiraterone, and MDV3100 pivotal phase 3 trials).
Other Names:
  • Webcore telephone survey system

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
Proportion of pain palliation responders
Time Frame: 6 weeks
Determine the proportion of pain palliation responders and the proportion experiencing pain progression will be presented along with 95% confidence intervals.
6 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
Clinical significance of pain score changes
Time Frame: 6 weeks
Determine the clinical significance of pain score changes. Pain score changes will be compared with each of the following "anchors": patient rating of change in pain, as well as changes in patient functional status, analgesic use, and various measures of disease status (imaging, PSA, circulating tumor cells). ROC curves derived using logistic regression analyses will be used to characterize the association between change in pain scores and clinically important improvement (defined by anchor variables).
6 weeks
Prevalence and trajectory of pain progression and pain palliation
Time Frame: 3 weeks
Descriptive statistics, including Kaplan-Meier, will be used to report findings for the proportion of asymptomatic men who ultimately develop pain, the median time until asymptomatic men develop pain, the median time until men with pain experience pain progression, and the median time until men with pain experience pain palliation.
3 weeks
Quantifying analgesic medication use
Time Frame: 26 months
Three different approaches to calculating a single value to represent total analgesic use will be compared: 1) equianalgesic tables published in guidelines of the National Comprehensive Cancer Network (NCCN) which convert various drugs and doses to "morphine equivalents"; 2) point scoring systems used in prior pivotal phase 3 trials based on the World Health Organization analgesic ladder in which lower points are assigned to weaker agents/doses and vice versa for stronger agents/doses; and 3) individual drug dose quantification, a dose recently suggested by the FDA but never empirically evaluated, in which each analgesic is considered individually and a 25% change in dose is considered an increase or decrease for each.
26 months
Frequency of pain reporting
Time Frame: 7 days
Seven consecutive days of reporting a pain item with a 24-hour recall item will be compared with a single administration of a pain item with a 7-day recall, in order to evaluate if the latter alone is sufficient for measuring pain.
7 days
Web-avidity of patients
Time Frame: 6 weeks
Identify the web-avidity of patients by summarizing patients' responses to questionnaire items about their use of internet and email.
6 weeks
