Tumor-Derived FGF19

To Identify and test thresholds, specificity and sensitivity for FGF19, (and associated markers) for detection in human blood of breast and colorectal in cancer patients, and see if occurs at higher rates than healthy controls.

Time frame: 1 year

The primary marker that the investigators will look for is FGF19, a factor of normally restricted spatially to parts of the intestine and gall bladder, especially following a meal. The investigators will test in cancer patients whether FGF19 (or other associated markers) are higher in the blood of subset of cancer patients. The investigator pose the question of whether FGF19 is actively secreted into blood by human tumors. In further examine its use as a blood biomarker, the investigators will address whether higher levels of FGF19 cutoffs can be detected in the blood of colorectal cancer or breast cancer patients over that of control participants. Successful completion of this goal will, for the first time, establish whether tumor production of FGF19 in human colorectal or breast tumors contributes to elevated levels in either, all or a subset of patients compared to blood levels in people without cancer.

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.
