View original scientific description
The Childhood Cancer Predisposition Study (CCPS) is a multi-center, longitudinal, observational study that will collect clinical and biological data and specimens from children with a cancer predisposition syndromes (CPS) and their relatives. The central hypothesis is that studying individuals at high risk for childhood cancer creates a unique opportunity for improving the understanding of carcinogenesis, tumor surveillance, early detection, and cancer prevention, which will collectively contribute to improving care and outcomes for pediatric patients with cancer and those with cancer predisposition syndromes (CPS).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Primary Subjects must meet all of the below criteria to be eligible for enrollment:
- Be less than 21 years of age at the time of enrollment
- Have a diagnosis of a specific CPS, whether they have had cancer or not
- Based on clinical laboratory testing demonstrating a Pathogenic or Likely Pathogenic germline variant and/or
- Based on well-established clinical diagnostic criteria and/or
- Based on high clinical suspicion of a specific CPS with clinical laboratory testing demonstrating a variant of uncertain significance (VUS) Affected Parents must meet all of the following criteria to be eligible for enrollment:
- Be the biologic parent of a Primary Subject and
- Carry a diagnosis (or obligate diagnosis) of the familial CPS Adult Affected Siblings must meet all of the following criteria to be eligible for enrollment:
- Be the biologic sibling of a Primary Subject and
- Carry a diagnosis (or obligate diagnosis) of the familial CPS Unaffected Parents and Siblings must meet all of the following criteria to be eligible for enrollment
- Be the biologic parent or sibling of a Primary Subject and
- Not carry a diagnosis (or obligate diagnosis) of the familial CPS Affected Family Members must meet all of the following criteria to be eligible for enrollment: 1\. Carry a diagnosis of (or obligate diagnosis of) the familial CPS. Documentation is requested but not required. More than one child from a Primary Family Unit may be a Primary Subject. An Unaffected Sibling may be reclassified as a Primary Subject if diagnosed with a CPS during childhood.
Exclusion criteria
- Individuals with a strong personal or family history of cancer without a genetic or clinical diagnosis of a specific CPS are not eligible for enrollment.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
