Long-term observational study to understand the genetic profiles of prostate cancer patients over time

Study Overview

Background: Prostate cancer is the most common type of cancer among men in the U.S. and is the second leading cause of cancer death among males, with about 191,930 new cases and 33,330 deaths estimated for 2020. Researchers have made strides in understanding the genetic factors that may increase the risk of developing prostate cancer. Studies have identified several key genetic markers linked to the disease, including BRCA1 and BRCA2 genes, which are also linked to breast and ovarian cancer, the HOXB13 gene linked to hereditary prostate cancer, and various genes associated with Lynch syndrome, a condition that increases cancer risk.

The Challenge: Despite these advancements, there is still much to learn about the genetic changes that can influence the risk and severity of prostate cancer. This includes identifying more genetic mutations that could affect how prostate cancer develops and behaves over time.

Study Goals: The goal of this study is to explore genetic alterations in prostate cancer patients, at both early and advanced stages, to find new markers that could be targeted with treatments or used to predict the disease's progression. Understanding these genetic factors more deeply could improve how we design future treatment trials and enhance our grasp of prostate cancer's natural progression.

Significance: By participating in this study, which will track the genetic profiles of prostate cancer patients over time, you could help scientists develop better treatments and potentially find ways to predict how aggressive the cancer will be, tailoring treatments more precisely for each individual.

Trial identification number

NCT04706663

The medicine(s) being studied.

This is an observational study, to follow the natural course of your disease based on your current treatment plan.

  • This is a long-term study focusing on understanding prostate cancer more deeply. You will not be required to visit the National Institutes of Health (NIH) regularly, unless you are already participating in another NIH study.
  • If you do visit NIH for any reason, we may collect blood, urine, and any leftover tumor samples to study your genes.
  • Whether or not you are regularly at NIH, you will be contacted every six months via phone or email to update your health information and review your medical records.
    • You will undergo regular tests for testosterone levels and prostate-specific antigen (PSA) to monitor your health.
    • Occasionally, you may be invited to provide additional blood samples for research purposes at NIH.

How does the new medicine work (Mechanism of Action)?

This study only involves following up over a long term. It does not provide any additional medicine or intervention.

What will be evaluated (Key endpoints)?
  • Your participation will continue for life as part of our effort to gather comprehensive data on the progression of prostate cancer. This includes tracking disease recurrence, response to therapies, and the duration of these responses.
  • We will collect detailed clinical information throughout the study, including updates from medical history, clinical tests, imaging studies, surgical reports, and any new genetic test results.
  • Our goal is to maintain active contact with you, adjusting our understanding of prostate cancer based on long-term observations of your health outcomes.

Who may participate (Inclusion criteria)?
  • Diagnosis: You must have prostate cancer confirmed through medical testing, and be 18 years or older in age
  • Genetic Requirements: You need to have certain genetic changes known as variants. These can be in any of the following genes: PIK3, AKT, PALB2, BRIP1, RAD50, RAD51, RAD54, RB1, SPOP, and genes involved in the Wnt/B-catenin pathway, CDK12, and MMR (MLH1, MSH2, MSH6, PMS2, EPCAM). You might also qualify if you have a high tumor mutational burden (TMB-high) or if you've responded exceptionally well to previous treatments. This study is looking for participants who meet these specific genetic criteria because they may respond differently to potential treatments.

Who may not participate (Exclusion criteria)?

This study requires a longer term commitment:

Study Commitment:
