Tracking ctDNA to guide hormone therapy switch in advanced breast cancer

Metastatic Invasive Breast Cancer

Part of Cancer, Skin clinical trials.

This trial checks if switching hormone therapy when ctDNA levels rise can help women with ER+/HER2- metastatic breast cancer. ctDNA is a tumor signal found in blood that may show early signs of resistance before scans do.

Summary written for real people, not researchers, by Clin2.

Phase
Phase 3

370 people
Ages
18 years and older
Study type
Interventional

Who can take part

  • You have ER+/HER2- advanced breast cancer that cannot be surgically removed and is not curable with radiation.
  • You are currently receiving or eligible for first-line treatment with an aromatase inhibitor plus a CDK4/6 inhibitor (palbociclib or ribociclib) for up to 3 years.
  • You have a tumor tissue sample available (with enough cancer cells) for genetic testing to design a ctDNA test.
  • You are age 18 or older and have good performance status (able to do daily activities without much help).
  • You agree to use effective contraception if you are of childbearing potential or have a partner who is.

Using a blood test to guide breast cancer therapy

This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.

Blood test monitoring during chemo before surgery for HER2-positive breast cancer

This trial tests whether a blood test (ctDNA) can help doctors monitor how well chemotherapy before surgery is working in women with HER2-positive breast cancer. It aims to see if changes in the blood can predict treatment success.

HER2-positive breast cancer trial using ctDNA to guide treatment

This trial tests a personalized treatment plan for HER2-positive breast cancer that has spread. It uses a blood test to track cancer DNA and adjust therapy, including treatments that may help prevent cancer from reaching the brain. The goal is to achieve long-term remission.

ctDNA-Guided Reduced Chemo in HR+/HER2- Breast Cancer

This study is testing whether using a ctDNA blood test can help doctors decide if patients with hormone receptor-positive, HER2-negative breast cancer can safely receive less intensive chemotherapy after surgery. The goal is to reduce side effects while still preventing the cancer from coming back.

Blood test monitoring in early-stage breast cancer

This trial uses a special blood test to track cancer signals (called ctDNA) during and after treatment for early breast cancer. It aims to see whether monitoring these signals can help guide follow-up and treatment decisions.

Blood test monitoring for early breast cancer recurrence

This trial uses a blood test to look for tiny bits of tumor DNA after treatment. If found, participants receive new drug combinations to try to prevent cancer from returning.
