What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study is looking at the gut microbiome—the collection of bacteria in your digestive system—in people with advanced non-small cell lung cancer. Researchers will collect stool and saliva samples before and during standard cancer treatment to see if the diversity of gut bacteria is linked to how well the treatment works or what side effects occur. The goal is simply to gather information, not to test a new drug or therapy.

What this could mean

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

What this could lead to
If successful, this study could reveal links between gut microbiome composition and treatment response or side effects in lung cancer patients.
What could go wrong
This is a small, early pilot study (82 participants) that only observes and measures—it does not test a new treatment. Results may not lead to direct clinical changes.

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

Inclusion Criteria: * 1\. Advanced/Metastatic non-small cell lung cancer NSCLC patients. * 2\. The patient himself/herself must be 18 years of age on day of signing informed consent. * 3\. The subject has signed the informed consent form. * 4\. The patient must be eligible to receive FDA approved and non-approved PD1 inhibitors (i.e. pembrolizumab, nivolumab) or PDL1 inhibitor (i.e. atezolizumab, durvalumab) either single agent or as combination therapy with chemotherapy, or be eligible to receive FDA approved and non-approved tyrosine kinase inhibitors. * 5\. The subject will be registered upon submission of the samples. When submitted on separate dates, the submission occurring later will be considered the date of registration Exclusion Criteria: * 1\. Those subjects who are determined clinically unstable of the participation of this study as determined by the PI or treating physician will be excluded and asked to focus on their treatment.
