New study tests tools to help families share cancer genetic results

NCT ID NCT04763915

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

The IMPACT Study is testing two online tools—GeneSHARE and LivingLabReport—to help people with inherited cancer gene variants share their results with family members and follow cancer screening guidelines. The study involves 720 adults who have a genetic variant linked to cancers like breast, prostate, or colorectal cancer. Researchers will measure whether these tools improve family communication and guideline-based care over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
GeneSHARE web-based toolkit and LivingLabReport website
What this could lead to
If successful, this could lead to better ways for people with inherited cancer risks to communicate with family and follow recommended screenings.
What could go wrong
This is a behavioral study, not a drug trial, so it won't directly treat or cure cancer. Results depend on participants' willingness to use the tools and share information.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 720 people

The number the study aims to enrol. It can still change while the study runs.

Started

Aug 2022

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Randomized Controlled Trial Eligibility: All trial participants will be autonomous adults who are capable of participating in the study Inclusion Criteria: * English-speaking men and women aged 18 years or older * Not adopted (i.e., have information about their biological relatives) * Have access to internet and a computer, tablet, or smartphone * Documented pathogenic/likely pathogenic variant in an inherited cancer gene that has CRM guidelines listed in the National Comprehensive Cancer Network (NCCN) Genetic/Familial Panel focused on Breast, Ovarian, and Pancreatic or Colorectal cancers * Must meet at least one of the following criteria: * Intervention A (GeneSHARE) criteria: Have at least one at-risk adult, living relative who either: * has not been told about the genetic test result by the participant * has not had their own genetic testing * Intervention B (LivingLabReport) criteria: Are non-adherent (i.e., either undertreatment or overtreatment) to at least one of the current NCCN CRM guidelines or if currently adherent, require ongoing cancer screening VUS Pilot Study Eligibility: All VUS pilot study participants will be autonomous adults who are capable of participating in the study. Eligibility criteria include: * English-speaking men and women aged 18 years or older * Not adopted (i.e., have information about their biological relatives) * Have access to internet and a computer, tablet, or smartphone * Documented VUS in an inherited cancer gene
