Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Genetic Information and Family Testing (GIFT) Study is designed to support the capacity, opportunity, and motivation of cancer patients to engage their relatives about inherited cancer susceptibility and provide support and services to those relatives to initiate GRE (including genetic testing) and prepare them to subsequently engage their clinicians in informed decision-making about cancer prevention and early detection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

GIFT features a web-based intervention that offers access to an online family communication program containing key facts about genetics, cancer risk, and the role of genetic testing and helps patients share health information with their first-and second-degree relatives, whom they can invite to join the study to receive education/support and access to low-cost genetic testing. Two design features of the intervention will be randomized and evaluated to determine the best approach for future scalability.

Those eligible will be offered enrollment into the Michigan-hosted intervention trial, and those who enroll will be randomized into 1 of 4 study arms. Patients can invite their relatives to enroll and receive genetic testing via Color. Families randomized to the arms with human Navigator support will also have access to a Family Health Navigator at Stanford University. Enrolled patients and relatives will be surveyed six months post-enrollment to collect additional information regarding their interactions with the GIFT platform and their experiences with genetic risk evaluation.

Study phase and approximate sample size is summarized below:

* Initial patient sample selected- 5250 patients
* Respondents to PICS survey- 3150 patients
* Pool of patients eligible for GIFT study invitation- 2930 patients
* Patient GIFT study participants- 880 patients
* Relatives invited to the GIFT study- 3520 relatives
* Relative GIFT study participants- 1584 relatives

Study phase and approximate sample size summarizes have been updated below and IRB approved 29SEP2025:

* Initial patient sample selected- 4300 patients
* Respondents to PICS survey- 2358 patients
* Pool of patients eligible for GIFT study invitation- 2030 patients
* Patient GIFT study participants- 412 patients
* Relatives invited to the GIFT study- 1236 relatives
* Relative GIFT study participants- 371 relatives

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

The trial is a 2x2 factorial prospective RCT

Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Participants

Randomization will be concealed from study participants; enrolled patients and relatives will not be aware that their family has been randomized into one of four trial arms and provided a different intervention experience than the other study participants. Concealment is necessary for this study so that the trial can observe differences across the trial arms without a) negatively impacting study enrollment and biasing the study, and b) causing unnecessary negative emotional reactions in study participants.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. diagnosed with any cancer at any stage in 2018-2019 and reported to the Georgia or California SEER registries
2. Been found to carry a pathogenic variant (PV) in one of 27 cancer susceptibility genes (see Table 4) according to the Georgia California Genetic Testing Linkage Initiative dataset
3. aged 18 or older
4. alive at the time of selection as determined through linkage with Georgia and California vital statistics data.

Additional eligibility criteria for Patient Trial Invitation will be evaluated from patient response to the PICS survey and will include patient report of:

1. Receipt of genetic testing for cancer risk
2. A positive test result (pathogenic variant; PV)

1. first-degree (biological parent, sibling, or biological child) or second-degree (biological half-sibling, aunt, uncle, nephew, niece, grandparent, or grandchild) relative of a patient enrolled in the study;
2. aged 18 or older;
3. alive at the time of study invitation;
4. relative lives in the United States or Canada (countries in which Color genetic testing is available, most people speak either English or Spanish, and test kit shipping costs are not exorbitant)

Additional eligibility criteria for Relative Trial Enrollment will be evaluated from relative response to the relative eligibility screening survey (see Appendix C) and will include:

1. confirmation from the relative that they have not received clinical genetic testing ordered by a doctor or genetic counselor within the past five years (proxy for having already been tested for the PV carried by the patient who invited them into the study);
2. confirmation of age 18 or older;
3. confirmation of first-degree (biological parent, sibling, or biological child) or second-degree (biological half-sibling, aunt, uncle, nephew, niece, grandparent, or grandchild) relation to the patient.
4. confirmation of residence in United States or Canada
