The purpose of this trial is to  designed to characterize the safety, tolerability, PK, PD, and preliminary activity of REC-4881 administered orally (PO) at multiple doses on a once daily schedule in participants with phenotypic classical FAP with disease involvement of the duodenum or the residual colon/rectum/pouch as the primary disease site.

The purpose of this study is to evaluate if the combination of trivalent adenovirus-5 (Tri-Ad5) vaccines and IL-15 superagonist N-803 reduces the incidence of colorectal neoplasms in patients with Lynch syndrome (LS).

The purpose of this study is to determine the prevalence of genetic mutations in cancer patients from various ethnic populations seeking care at Mayo Clinic cancer clinics.

The purpose of this study is to develop a biorepository of blood samples  from cancer patients participating in the Gemini (IRB 19-006717) protocol. These samples will be used for future biomarker discovery and other translational studies. 

The purpose of this study is to evaluate the integration of cancer pan-genetic testing into a cancer clinical practice and understand both its use and effect in “real world” practice conditions.

The purpose of this study it to develop culturally appropriat, respectful, trusted, and collaborative means to engage and recruit American Indians (AI) affected by cancer (newly diagnosed cancer participants, participants undergoing cancer treatment, and cancer survivors) for molecular characterization of their tumors.

The purpose of this study is to to determine the sensitivity and specificity of a second-generation multi-target stool DNA test (mt-sDNA 2.0) (Cologuard 2.0®, Exact Sciences Corporation) for colorectal neoplasia (CRN) in subjects with Lynch syndrome.

The overall hypothesis is that the early detection of genetic variants leads to early interventions in cancer development.  This will lead to lower rates of cancer development and will eventually result in lower death rate from cancer.  In the short term, healthcare utilization and costs will increase due to the early interventions and treatments.  In the long term, benefit will start to emerge due to the lower disease development, lower death rate, and retaining of the quality of life and life expectancy.

The purposes of this study are to analyze the frequency and severity of adverse events associated with low-dose encapsulated rapamycin in Familial Adenomatous Polyposis (FAP), to determine the recommended phase 2 dose (RP2D) based on assessment of safety, long-term tolerability, optimal blood levels, and clinical benefit, and to determine the effectiveness of eRapa in delaying polyp progression in patients with FAP compared to historic controls.

The purpose of this study is to create a database of clinical information and a repository of biological specimens for genetic, molecular and microbiological research to better understand hereditary cancer and help develop new therapies and preventive strategies.

The goal of the study is to create a database of clinical information and a repository of biological specimens for genetic, molecular and microbiological research to better understand hereditary cancer and help develop new therapies and preventive strategies.

Tapestry is a Mayo Clinic research study, which includes receiving genetic sequencing data from Helix, up to the full whole exome dataset. The goal of this study is to provide: (i) an immediate interpretation of ancestry/genealogy and several non-disease traits, as well as, clinically actionable variants for an inherited form of high cholesterol called familial hypercholesterolemia (FH), breast and ovarian cancer (HBOC), and Lynch syndrome to each participant; (ii) an additional subset of focused clinically actionable genetic findings, such as, certain types of hereditary cancers, hereditary heart conditions and severe responses to certain medications, will be returned to the provider and to the participant, via the provider, genetic counselor consultation, and/or Mayo Clinic research interpretation; (iii) storing of genomic and phenotypic data for future research analysis.

The goals of this study are to collect and store biospecimens (e.g., blood, urine, saliva, stool) in order to support future research. These biospecimens will be tested and used to better understand why a disease or disorder occurs and how it progresses over time. This knowledge could aid future patients.

This phase II trial studies the side effects of erlotinib hydrochloride and how well it works in reducing duodenal polyp burden in patients with familial adenomatous polyposis at risk of developing colon cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

THe purpose of this study is to examine the current and (potential) future therapeutic relevance of pharmacogenomics (PGx) testing for a cohort of cancer patients in order to improve quality of life (QOL) in patients receiving clinical care at Mayo Clinic.

The purpose of this study is to review clinical endoscopy reports, pathology reports, and other medical records related to standard-of-care endoscopic evaluations for all participants in the parent study, MAY2016-07-01, who provide consent for the review of their medical records.  There have been reports of rapid progression of recurrent polyps after completion intervention and follow up under the parent protocol.  A review of literature found insufficient data to determine whether or not there is a longer term safety risk to the participant in MAY2016-07-01. 

GRAIL is using deep sequencing of circulating cell-free nucleic acids (cfNAs) to develop assays to detect cancer early in blood. The purpose of this study is to collect biological samples from donors with a new diagnosis of cancer (blood and tumor tissue) and from donors who do not have a diagnosis of cancer (blood) in order to characterize the population heterogeneity in cancer and non-cancer subjects and to develop models for distinguishing cancer from non-cancer.
