Adding an Immunotherapy Drug, MEDI4736 (Durvalumab), to the Usual Chemotherapy Treatment (Paclitaxel, Cyclophosphamide, and Doxorubicin) for Stage II-III Breast Cancer
NCT06058377
Recruiting
This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and... Read More

A Study of Camizestrant in ER+/HER2- Early Breast Cancer After at Least 2 Years of Standard Adjuvant Endocrine Therapy
NCT05774951
Recruiting
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard endocrine therapy in patients with ER+/HER2 - early breast cancer with intermediate or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy) and standard adjuvant endocrine therapy (ET) for at least 2 years and up to 5 years.

National Cancer Institute "Cancer Moonshot Biobank"
NCT04314401
Recruiting
This trial collects multiple tissue and blood samples, along with medical information, from cancer patients. The "Cancer Moonshot Biobank" is a longitudinal study. This means it collects and stores samples and information over time, throughout the course of a patient's cancer treatment. By looking at samples and information collected from the same people over time, researchers hope to better understand how cancer changes over time and over the course of medical treatments.

Fisetin to Improve Physical Function in Stage I-III Breast Cancer Survivors
NCT05595499
Recruiting
This phase II trial tests whether fisetin works to improve physical function in women who have received chemotherapy for stage I-III breast cancer treatment. Fisetin is a naturally occurring substance that is found in strawberries and other foods. Fisetin eliminates cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release ha... Read More
