Recruiting studies
- NCT07067138Recruiting
Genetic testing to guide treatment for advanced breast cancer
This study looks at the genes in your cancer to find a treatment that might work better for you. It tests your tumor sample to match you with a drug that targets your cancer's specific weaknesses.
Bethesda, MarylandAges 18–120 - NCT05333328RecruitingPhase 4
Test of ovarian function suppression for low-risk premenopausal node+ breast cancer
This trial studies whether ovarian function suppression (a treatment that lowers hormone production from the ovaries) helps women with hormone-receptor positive, HER2-negative breast cancer that has spread to lymph nodes, but who have a low-risk result on a genomic test. It may help reduce breast cancer recurrence while avoiding more intensive treatment for those who are lower risk.
Seoul, KoreaAges 20–50 - NCT07071272Recruiting
Comparing two breast imaging methods before surgery
This trial compares a special mammogram with dye (CEDM) to MRI for women already diagnosed with invasive breast cancer. The goal is to see if CEDM works as well as MRI for planning surgery, potentially offering a faster or easier option.
Verona, ItalyAges 30 years+ - NCT07071038RecruitingPhase 2
Switching medication to relieve side effects from aromatase inhibitors
This trial tests whether switching to a different aromatase inhibitor or using standard treatments works better for managing side effects in breast cancer survivors. It aims to help you stay on hormone therapy longer with fewer discomforts.
Lebanon, New HampshireAges 18 years+ - NCT07070791Recruiting
Exercise program for arm strength and fitness after breast cancer
This trial tests whether a combination of arm-strengthening and aerobic exercises helps breast cancer patients who are at least 15 months past surgery and not very active. The goal is to see if this home-based program improves arm function and overall fitness.
Ankara, StateAges 18–80 - NCT07073755Recruiting
Study of next treatments after targeted therapy resistance for advanced breast cancer
This study looks at what happens when people with advanced breast cancer switch to a new treatment after their cancer becomes resistant to targeted therapies like CDK4/6 inhibitors, PIK3CA inhibitors, or T-DXd. Researchers want to understand which next treatments work best in real life.
Changsha, HunanAges 18 years+ - NCT06984250Recruiting
Shorter radiation with extra focus on tumor site for breast cancer
This trial tests a shorter course of radiation therapy that includes an extra dose to the tumor site for women with early-stage breast cancer. It aims to make treatment more convenient and effective after breast-conserving surgery.
Taipei, TaiwanAges 20–85 - NCT07057427RecruitingPhase 3
Nab-paclitaxel vs TCbHP for HER2-positive early breast cancer
This trial compares two different drug combinations given before surgery to shrink HER2-positive breast cancer tumors. The goal is to see which combination works better and has fewer side effects.
Zhengzhou, HenanAges 18–70 - NCT07056205Enrolling by invitation
Comparing hormone markers in first and returning breast cancer
This trial looks at how certain proteins (ER, PR, and HER2/neu) on breast cancer cells change when the cancer comes back in the same spot. Knowing this could help doctors choose the best treatment for your recurrence.
SohagAges Any age - NCT07059884Recruiting
Exercise program to help people with cancer stay active
This trial tests a distance-based exercise program designed to help people on chemotherapy maintain their physical function and prevent disability. It is for patients with certain cancers who are working full-time and can participate in moderate physical activity.
Dublin, CaliforniaAges 18 years+ - NCT07054190RecruitingPhase 2
Testing inavolisib for early-stage PIK3CA-mutated breast cancer
This study tests a new drug called inavolisib for people with early-stage breast cancer that has a specific genetic change (PIK3CA mutation). The goal is to see if adding this drug to standard hormone therapy is safe and effective before surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT06989450Recruiting
Digital support for women on hormone therapy for breast cancer
This trial tests a smartphone app called Sidekick to help women with early-stage breast cancer stick to their hormone therapy and feel more confident managing their health. If you were diagnosed with stage I, II, or III breast cancer after September 2023 and are starting hormone therapy, this program might help you stay on track.
ReykjavikAges 18 years+ - NCT06991946Recruiting
Genomic profiling for metastatic breast cancer in Spain
This study looks at how genetic testing of your tumor might affect the treatment plan for your metastatic breast cancer. It aims to help doctors choose the best therapy based on your tumor's profile.
Barcelona, BarcelonaAges 18 years+ - NCT07053085RecruitingPhase 2
Surgery or radiation for stable HER2+ breast cancer spread
This study tests whether combining surgery or strong focused radiation with standard treatment can help people whose HER2-positive breast cancer has spread to a few spots (5 or fewer) in the body, but not the brain. It's for patients whose cancer is stable after at least 3 months of first-line therapy.
Basking Ridge, New JerseyAges 18 years+ - NCT07037576Recruiting
Breast reconstruction study for patients needing radiation after mastectomy
This study compares two types of breast reconstruction for women who need radiation therapy after their mastectomy: one-stage reconstruction using a permanent implant placed in front of the chest muscle, versus the standard two-stage approach where a tissue expander is used first and replaced with a permanent implant later. The goal is to see which method works better and is safer for patients who require post-mastectomy radiation.
Henan, HenanAges 18–70 - NCT07042243Recruiting
Florida ASCENT cancer study for patients and providers
This study looks at cancer care in Florida. If you have had cancer in the past and are not currently getting active treatment (like chemotherapy or radiation), this study may help researchers understand how to improve care.
Gainesville, FloridaAges 18–100 - NCT07044310RecruitingPhase 2
Probiotics for preventing bone loss during breast cancer hormone therapy
