Symptom monitoring and health for women on hormone therapy for breast cancer
This trial tests a mobile health program to help women manage symptoms and stay healthy while taking hormone therapy (like tamoxifen or anastrozole) for early-stage breast cancer. It involves using a smartphone app and an electronic pill bottle to track your health and medication.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05003635Recruiting
Testing a vacuum device to improve breast fat reconstruction
This trial tests whether an external vacuum device (EVEBRA) can help surgeons place fat grafts more effectively during breast reconstruction. You may be able to try the device in an office visit and, if you qualify, receive reconstruction using only your own fat.
Maastricht, LimburgAges 23–69 - NCT05902988RecruitingPhase 1/Phase 2
Study of VLS-1488 for advanced cancers
This early-phase study tests VLS-1488, a new cancer medicine, in people with advanced cancers that have limited treatment options. It may help by finding a safe dose and whether it can shrink or control tumors.
Los Angeles, CaliforniaAges 18 years+ - NCT05706129RecruitingPhase 1/Phase 2
Testing targeted imaging and therapy for advanced solid tumors
This early-phase study tests two radioactive medicines that first help doctors see tumors and, in some parts of the study, treat them. It may help people with advanced, hard-to-remove cancers that have a specific tumor marker (CA IX).
MelbourneAges 18 years+ - NCT06640881RecruitingPhase 2
Repeat breast-conserving surgery with partial reirradiation
This trial tests a new approach for women whose breast cancer has returned in the same breast after earlier surgery and radiation. Instead of removing the whole breast, doctors will remove only the tumor again and give a small, focused dose of radiation before surgery, aiming to preserve the breast.
AmsterdamAges 50 years+ - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
Tucson, ArizonaAges 18 years+ - NCT04349527Recruiting
Comparing breast-conserving surgeries and how you feel after
This trial compares two breast-conserving surgery techniques to see how they affect cosmetic results (how the breast looks), quality of life, and patient satisfaction. It may help guide the best surgical approach for people eligible for breast conservation.
BudapestAges 18–65 - NCT05056857Recruiting
Study immune-web changes in ER+ breast cancer on tamoxifen
This trial studies how the immune system forms “neutrophil extracellular traps” (immune web material) in people with ER-positive breast cancer who take tamoxifen. It aims to understand whether tamoxifen changes this immune activity over time, which may help explain how it works.
Houston, TexasAges 18 years+ - NCT07664579Recruiting
Couples coping together against cancer support program
This trial tests a supportive care program for couples facing cancer. It helps you and your partner work together to manage the challenges of a cancer diagnosis.
Duarte, CaliforniaAges 18 years+ - NCT07765927Recruiting
Exercise program for people with breast or gynecologic cancer
This study is testing whether an exercise program for people with breast or gynecologic cancer is feasible to run. It aims to see if patients can participate and follow the program.
Iowa City, IowaAges 18 years+ - NCT04904757Recruiting
CESM contrast mammogram screening for dense breasts
This trial tests a newer kind of breast screening scan that uses a special dye (contrast) to better show breast tissue. It may help people with very dense breasts get clearer screening images.
Charlottesville, VirginiaAges 40–69 - NCT04794075Recruiting
Nursing and education support for women on hormone breast therapy
This trial tests a structured nursing and education program to support people with non-metastatic breast cancer who take hormone-blocking treatment. It may help you manage side effects and stay supported during follow-up, using online questionnaires and scheduled sessions.
Bourg-en-BresseAges 18–75 - NCT06977698Recruiting
Detecting cancer margins during breast surgery
This study tests a new method to check for leftover cancer cells and lymph node spread during breast surgery. It may help doctors make sure all cancer is removed the first time.
NottinghamAges Any age - NCT06150664RecruitingPhase 1
Study of CTX-8371 for advanced cancers no longer helped by standard therapy
This trial tests a new drug called CTX-8371 for people with advanced cancers (melanoma, head and neck, lung, triple-negative breast, or Hodgkin lymphoma) that have stopped responding to standard treatments, especially immunotherapy. It is a first-in-human study, meaning doctors are learning if the drug is safe and how well it works.
Margate, FloridaAges 18 years+ - NCT04050423Recruiting
Ultrasound scans to better study breast lumps
This study tests whether special ultrasound pictures and “spectroscopy” measurements can help characterize breast masses that may be cancer. It may help doctors tell more about what a lump is and guide next steps.
Toronto, OntarioAges Any age - NCT05490433Recruiting
Robot-assisted versus open nipple-sparing mastectomy with reconstruction
This trial compares two surgical approaches to remove the breast using a nipple-sparing mastectomy and do immediate breast reconstruction—either robot-assisted or open surgery. It aims to see how well each method works and how patients do afterward.
ChangwonAges 19–70 - NCT05549024RecruitingEarly Phase 1
PET/CT scan study for certain prostate, brain, or breast cancers
This early-phase study tests special PET/CT scans using a radioactive tracer to see cancer areas that have specific targets. It may help doctors better visualize tumors and plan next steps, using scans that you may already be familiar with (FDG) plus targeted tracers.
BeijingAges 18 years+ - NCT05768932RecruitingPhase 1
Study drug for advanced cancers or relapsed AML
This Phase 1 trial tests BAL0891, a new study treatment, in people with advanced solid tumors that have run out of treatment options, or in relapsed/refractory acute myeloid leukemia (AML). The goal is to find a safe dose and see how well it may work in these hard-to-treat cancers.
