Study of TQB2930 for breast cancer that has returned or spread
This trial tests a new drug called TQB2930 alone or with other treatments for people with recurrent or metastatic breast cancer. It may help if you have a type of breast cancer called HER2-positive and have not had many prior treatments for advanced disease.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT06307249RecruitingPhase 1
Precision therapy for solid tumors targeting CDK4/6 and VEGF
This trial tests a combination of two targeted drugs for advanced solid tumors like colorectal, lung, breast, and genitourinary cancers. The goal is to see if blocking certain proteins and a long RNA molecule can slow tumor growth.
Tripoli, North LebanonAges 18 years+ - NCT06227117RecruitingPhase 2
Study of DV and Toripalimab before surgery for HER2-low breast cancer
This trial tests a combination of two drugs (DV and Toripalimab) with chemotherapy before surgery for a specific type of breast cancer (HER2-low, HR-negative) that has not spread too far. The goal is to see if this approach can shrink the tumor and improve outcomes.
Changsha, HunanAges 18 years+ - NCT05861271RecruitingPhase 2
Adjuvant pyrotinib plus capecitabine for tiny HER2 breast cancer
This trial studies whether adding pyrotinib and capecitabine after surgery can lower the risk of cancer coming back in people with very small, lymph-node–negative, HER2-positive breast cancer. It’s for patients who fit specific tumor size and HER2 test results and who can safely take chemotherapy-like medicines and stay on contraception during treatment.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06334471Recruiting
Whole genome sequencing for breast cancer
This trial uses whole genome sequencing, a test that reads the complete set of your DNA, to study breast cancer tissue. This may help doctors learn more about the disease and find better treatments.
SeoulAges 19 years+ - NCT06149130RecruitingPhase 2
Testing adebrelimab, dalpiciclib, and hormone therapy for advanced breast cancer
This trial tests a combination of a new immunotherapy drug (adebrelimab) with a targeted pill (dalpiciclib) and standard hormone therapy for women with advanced hormone receptor positive, HER2 negative breast cancer. It may help patients who have not yet had certain prior treatments, aiming to slow the cancer's growth.
