An observational study in Chronic Prostatitis (CP), Chronic Pelvic Pain Syndrome (CPPS) and Painful Bladder Syndrome (PBS), sponsored by Boston Children's Hospital. Recruiting at 1 site in United States. Per ClinicalTrials.gov, last updated 2026-06-11.
Sponsored by Boston Children's Hospital · Observational
Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a condition with several causes of which some remain unknown. It is believed that some types of CP may be genetic or passed down (inherited) from one generation to the next.
In this study, we are collecting genetic material and medical information to try to determine if genetic factors play a role in CP/CPPS. We will be collecting DNA (from Blood/Saliva sample) and urine from each participant. Bladder tissue from affected individuals will also be collected. Individuals and families with CP/CPPS will be enrolled. Family members of an individual with CP/CPPS are eligible whether or not they also experience CP/CPPS symptoms.
We would like to determine if chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has a genetic cause. We will be attempting to further describe the symptoms of CP/CPPS and to correlate them with changes in your genes. We will use several types of genetic testing; linkage analysis, whole exome sequencing and candidate gene studies. Each individual participant will be required to give a DNA sample (via Blood/Saliva), a urine sample and answer questionnaires. Affected participants will also be asked to provide a bladder sample from a clinical biopsy. All samples will be stored. Travel to Boston NOT required.
236 studies on the registry are indexed under Cystitis, Interstitial; 35 are open to participants now.
This study's planned enrollment of 500 is above the median of 100 across 63 observational studies indexed under Cystitis, Interstitial.

We are collecting individuals with a diagnoses of CP/CPPS and their family members (with or without symptoms) from North America (United States and Canada). Preference is given to families with multiple affected individuals (males or females with IC/BPS/CPPS).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Participants With Candidate Disease-Causing Genetic Variant(s) Associated With CP/CPPS or IC/BPS
DNA from blood/saliva and, when available, bladder or skin tissue will be analyzed using linkage analysis, whole exome/genome sequencing, and candidate gene approaches to identify candidate disease-causing variants associated with CP/CPPS, IC/BPS, PBS, or BFS. The measure will be summarized as the number of participants with candidate disease-causing variant(s), and when applicable, co-segregation of variants with affected status or symptoms.
Time frame: From enrollment until completion of genetic analysis for the participant or family, up to 22 years.
Plan to share: Yes — Data from individual participants may be shared with other researchers. Other research studies will be approved by our internal review board and participants samples and data will be de-identified.
Supporting information: Statistical analysis plan, Informed consent form
Time frame: We will store study information and samples indefinitely and may share this information with future collaborators. All shared samples and data will be de-identified.
Access criteria: De-identified data may be shared with other CP/CPPS researchers or other BCH researchers
