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

Hormone Receptor-Positive Breast CancerHigh-risk Breast CancerEarly-Stage Breast CancerHER2-negative Breast CancerctDNA MonitoringBreast Cancer Early Stage Breast Cancer (Stage 1-3)

Part of Cancer, Skin clinical trials.

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.

Who can take part

  • You are a woman between 18 and 75 years old with hormone receptor-positive (HR+) and HER2-negative breast cancer.
  • You must have a tumor that is at least stage T1c-2N0M0 with high-risk features, or T3N0M0, or any tumor with positive lymph nodes.
  • You need to have not received any prior treatment for this breast cancer (like chemotherapy, radiation, or hormone therapy).
  • Your overall health should be good enough that you can do most daily activities (ECOG 0-1).
  • You cannot have had another cancer in the last 5 years (except for some cured skin cancers or cervical carcinoma in situ).
  • You must not have serious lung or heart problems, active infections, or certain viral infections like HIV or untreated hepatitis B/C.

NCT07366112Recruiting· Phase 2
CDK4/6 inhibitor plus hormone therapy before breast cancer surgery

This trial tests a combination of a CDK4/6 inhibitor (a type of targeted therapy) with hormone therapy given before surgery for early-stage breast cancer that is hormone receptor-positive and HER2-negative. It aims to see if this approach can shrink tumors and improve outcomes.

A study of hormone therapy with or without a targeted drug for breast cancer

This trial tests if adding a targeted drug (CDK4/6 inhibitor) to hormone therapy works better than hormone therapy alone for women with a certain type of breast cancer (HR+/HER2-). The study measures the activity of tumor cells (Ki-67) to help decide treatment.

NCT04985266Recruiting· Phase 2
Watch blood DNA for early breast cancer return, then add palbociclib

This study checks for early signs that ER-positive, HER2-negative breast cancer may be coming back by testing your blood for cancer DNA. If signs are found, it tests whether adding palbociclib plus fulvestrant works better than standard hormone therapy alone to prevent recurrence.

Neoadjuvant treatment study for certain breast cancers

This Phase 2 study tests a “precision platform” approach—treatment before surgery—based on specific test results from your breast tumor. It may help determine whether the treatment plan works better for people with particular breast cancer subtypes and healthy organ function.

NCT06556862Not yet recruiting· Phase 2
Dalpiciclib plus HDAC inhibitor for advanced breast cancer after CDK4/6 inhibitor

This trial tests a new combination of two drugs (dalpiciclib and an HDAC inhibitor) for people with hormone receptor-positive, HER2-negative advanced breast cancer that has progressed after a CDK4/6 inhibitor. The goal is to see if this combination can help control the cancer.

ctDNA in HER2-positive early breast cancer before surgery

This trial is testing whether monitoring ctDNA (genetic material from the tumor in your blood) can help guide treatment for HER2-positive breast cancer before surgery. It is for people with early-stage (Stage II or III) disease who have not yet started treatment.
