Atezolizumab and sacituzumab govitecan to prevent recurrence in triple-negative breast cancer
This trial tests whether combining sacituzumab govitecan with atezolizumab can prevent cancer from coming back in people with triple-negative breast cancer who have residual disease after pre-surgery chemotherapy and detectable circulating tumor DNA.
NIH-funded research (17)
Early-stage science funded by the US National Institutes of Health. Most of these projects don't enroll patients, but they show what is being worked on.

Predicting prostate cancer treatment response using tumor DNA from blood
This project seeks to find out if analyzing tumor DNA in blood can show which men with advanced prostate cancer will respond to androgen-targeted and PSMA-directed therapies.
-
Monitoring breast cancer treatment using blood tests for tumor DNA
This study is looking at how to better treat people with early and locally advanced breast cancer by checking for tiny bits of cancer DNA in their blood, which could help doctors spot any remaining cancer sooner and tailor treatments to each patient, reducing the chance of unnecessary therapies.
-
Monitoring brain tumor treatment with blood tests and special MRI
This research aims to find better ways to track how well glioblastoma brain tumors respond to treatment using blood tests and advanced MRI scans.
-
Using blood tests to tailor treatment for lymphoma patients
This study is looking at how a simple blood test can help doctors tailor treatment for people newly diagnosed with diffuse large B-cell lymphoma, so they can get the right amount of therapy to reduce side effects while still being effective.
-
Combining blood tests and MRI to predict treatment response in early breast cancer
This study is looking at how using blood tests to check for cancer DNA along with MRI scans can help doctors see how well early breast cancer patients are responding to their chemotherapy before surgery, so they can make better treatment decisions and improve outcomes for everyone involved.
-
Using blood tests to identify prostate cancer characteristics for better treatment predictions
This study is looking at how bits of cancer DNA found in your blood can help doctors understand your prostate cancer better and predict how well different treatments might work for you, especially when regular biopsies are tough to do.
