Genetic Evaluation of Men (GEM)

April 28, 2025 updated by: Sidney Kimmel Cancer Center at Thomas Jefferson University
This is a prospective research registry and prospective genetic testing cohort study. The goal is to collect personal medical and cancer history data, family cancer data, exposure history, and biospecimens to support research focused on optimal genetic testing strategies for men with prostate cancer with the ultimate goal of informing national guidelines focused on genetic evaluation for prostate cancer.

Study Overview

Status

Status

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

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

Objectives:

  1. Collect detailed family cancer histories, personal medical history, prostate cancer clinical features, and exposure history from men with prostate cancer and men without prostate cancer to support studies focused on identifying hereditary cancer syndromes and genetic/epidemiologic factors predisposing to prostate cancer susceptibility.
  2. Collect behavioral measures to support research focused on assessing the needs of men undergoing cancer risk evaluation and satisfaction with the process.
  3. Create and maintain a biospecimen bank with specimens from men with prostate cancer and without prostate cancer to support studies focused on genetic alterations predisposing to prostate cancer risk.
  4. Perform targeted and broad-scale genetic and genomic sequencing to detect genetic alterations related to prostate cancer risk.
  5. Develop mechanisms to recontact participants with updates on research genetic results to guide genetic testing for inherited prostate cancer risk.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Men with a personal history of PCA; Unaffected males who are at higher risk for prostate cancer

Description

Inclusion Criteria:

  1. Men with a personal history of prostate cancer
  2. Unaffected males who are at higher risk for prostate cancer

Exclusion Criteria:

  1. Age < 18 years

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
