NCT ID NCT07246759

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 This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study is developing a blood test called NeutroFlow that measures specific immune cells (neutrophils) to predict whether cancer patients will benefit from immunotherapy. Researchers will collect blood samples from 600 patients with several types of cancer before they start treatment. The goal is to create a tool that helps doctors personalize cancer care.

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 blood test could help doctors decide which patients are most likely to benefit from immunotherapy, avoiding unnecessary treatments.
What could go wrong
This is an early-stage study to develop and validate a test, not a treatment. The test may not accurately predict outcomes for all patients or cancer types.
