NCT ID NCT04533555

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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at whether offering genetic testing to all young adults with cancer (ages 18-39) is better than only testing those who meet certain guidelines. About 749 participants were randomly assigned to either universal testing with a broad gene panel or standard testing based on doctor's judgment. The goal was to see which approach finds more inherited genetic risks that could affect patients and their families.

What this could mean

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

Active substance
broad gene panel for young adult cancers
What this could lead to
If successful, this could lead to a simpler, more effective way to identify genetic risks in young cancer patients and their families.
What could go wrong
This is a completed study comparing testing strategies, not a treatment trial. Results may not change current practice if universal testing proves too costly or impractical.

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients will be eligible if they meet the following criteria: * Diagnosed with a solid tumor between age 18-39 (patients may be 40 years of age at time of enrollment) * Within one year of diagnosis with index cancer * Have had at least two visits at Penn Medicine for the cancer diagnosis (to exclude one-time second opinions) Exclusion Criteria: Patients will be excluded if they meet any of the following criteria: * Diagnosis of in situ cancer, thyroid cancer (papillary or follicular), or leukemia Breast cancer diagnosis (aim 1 only) * Have a known genetic predisposition to cancer * Underwent genetic testing after this cancer diagnosis * Have a benign neoplasm
