Recruiting studies
- NCT05232409RecruitingPhase 1
Zeaxanthin in metastatic cancer, alone or with pembrolizumab
This Phase 1 study tests whether zeaxanthin is safe and what dose to use in people with metastatic cancer. It also studies zeaxanthin together with pembrolizumab (an immunotherapy) to see if the combination is tolerable after cancer has progressed despite PD-1/PD-L1 treatment.
Paramus, New JerseyAges 18–99 - NCT05283330RecruitingPhase 1
Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.
Chicago, IllinoisAges 18 years+ - NCT05288777RecruitingPhase 2/Phase 3
Testing follow-up chemo and radiation for high-risk breast cancer
This trial studies a standard follow-up treatment plan that combines chemotherapy and radiation after surgery, and it looks for blood/tissue “biomarkers” that predict who benefits most. If you have high-risk breast cancer that didn’t fully disappear after initial (neoadjuvant) chemo, you may be eligible to help guide better future treatment choices.
Charlottesville, VirginiaAges 18 years+ - NCT05292742RecruitingPhase 2
Continue targeted breast cancer therapy or switch to a new combo
This Phase 2 study compares two treatment plans after breast surgery when cancer did not fully disappear before surgery. It tests whether adding trastuzumab, pyrotinib, and capecitabine works better than continuing the original targeted therapy.
Fuzhou, FujianAges 18–75 - NCT05296564RecruitingPhase 1/Phase 2
TCR cell therapy for NY-ESO-1 positive metastatic cancers
This study tests a customized immune-cell treatment made from your own T cells to attack cancers that have NY-ESO-1. It may help shrink tumors in people with metastatic or hard-to-treat cancer when other treatments have not worked.
JerusalemAges 18–70 - NCT05301881RecruitingPhase 2
Keep the same treatment after limited metastatic growth
This study tests whether continuing your current systemic (whole-body) therapy is safe and helpful when only 1–2 metastatic spots start growing. It also checks whether adding local treatment (such as radiation or ablation) to those spots can better control the cancer.
AlkmaarAges 18 years+ - NCT05318469RecruitingPhase 1/Phase 2
Ivermectin with immunotherapy for metastatic triple-negative breast cancer
This trial studies whether ivermectin, given together with immunotherapy (balstilimab or pembrolizumab), can help treat metastatic triple-negative breast cancer. It mainly looks at safety first, and may also explore how well the treatment works for people whose cancer has spread.
Los Angeles, CaliforniaAges 18 years+ - NCT05334459Recruiting
Radiation and medicines after surgery for new metastatic breast cancer
This trial looks at giving radiation and anti-cancer medicines after surgery to treat newly diagnosed (de novo) metastatic breast cancer. It may help patients by improving local control of the breast area while also treating cancer throughout the body.
AnkaraAges 18–80 - NCT05349227Recruiting
After-cancer digital coaching and wearable tracking outcomes study
This study tests a digital health coaching program (using phone/tablet check-ins and wearable data) to understand health and quality-of-life outcomes after cancer treatment. It may help you learn healthy habits and track progress over time.
Gainesville, FloridaAges 18 years+ - NCT05362760RecruitingPhase 4
Abemaciclib plus hormone therapy, with digital side-effect tracking
This trial tests whether adding abemaciclib to standard hormone (endocrine) therapy can improve outcomes for certain types of advanced breast cancer. It also uses a phone app to help you and the team track side effects so problems can be caught early.
AalenAges 18 years+ - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Los Angeles, CaliforniaAges 12 years+ - NCT05378204Recruiting
Testing DNA repair marker for PARP inhibitor resistance
This study looks at specific DNA “damage repair” proteins as a marker to understand why some BRCA-mutated breast cancers may resist PARP inhibitor treatment. Your biopsy (or existing biopsy) helps researchers study whether these lab markers relate to how well PARP inhibitors work.
BordeauxAges 18 years+ - NCT05379153RecruitingPhase 3
Laser treatment for vaginal dryness after breast cancer
This Phase 3 study tests laser therapy to treat bothersome vaginal dryness (with or without pain during sex) in women who have finished breast cancer treatment. If you qualify, you may receive the study laser procedure to see if it improves symptoms compared with standard care.
Ann Arbor, MichiganAges 22 years+ - NCT05388149RecruitingPhase 2
Neratinib plus Kadcyla to treat leftover HER2 breast cancer
This trial studies whether adding neratinib to Kadcyla (T-DM1) can help eliminate “molecular residual disease,” meaning tiny traces of cancer left after surgery and standard HER2 treatment. It’s for adults with HER2-positive breast cancer who still test positive after a short course of Kadcyla, with no signs of cancer returning or spreading on scans.
Toronto, OntarioAges 18 years+ - NCT05396612Recruiting
Studying the immune response in non-cancer-spread breast surgery
This study looks at how your immune system changes while you receive standard breast cancer treatment around the time of surgery. The goal is to learn why some people respond better than others, which could help future treatment choices.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05414357Recruiting
Sleep problems study in breast cancer and effects on thinking
This study looks at how sleep problems affect thinking and daily quality of life in people treated for early breast cancer. It may help researchers understand which sleep issues to target to improve well-being during or after treatment.
CaenAges 45–65 - NCT05422794RecruitingPhase 1
Adding a new drug plus pembrolizumab to standard chemo for TNBC
This trial studies whether adding a new anti-cancer drug (ZEN-3694) and the immunotherapy drug pembrolizumab to standard chemotherapy (nab-paclitaxel) can work better for advanced triple-negative breast cancer. It’s testing safety first (Phase 1) and, for some patients, how well the treatment controls the cancer.
Boston, MassachusettsAges 18 years+ - NCT05430399RecruitingPhase 3
Utidelone vs docetaxel for HER2-negative breast cancer
This trial compares utidelone with docetaxel in people with HER2-negative advanced or metastatic breast cancer. It aims to see which treatment works better and is safer for controlling the cancer and helping patients live longer.
Guangzhou, GangdongAges 18 years+ - NCT05440929Recruiting
Testing a breast-cancer prognostic tool with U.S. clinicians
This study checks how acceptable, appropriate, and easy to use a metastatic breast-cancer “prognostic calculator” is for clinicians. It may help clinicians use the tool in real practice to support care decisions for people with metastatic breast cancer.
Chapel Hill, North CarolinaAges Any age - NCT05452213RecruitingPhase 4
Study patterns of ribociclib response and resistance in breast cancer
This trial looks at how well ribociclib works and why it may stop working over time in people with advanced, hormone-receptor–positive, HER2-negative breast cancer. It also analyzes blood and tissue samples to help researchers understand resistance patterns and improve future treatment decisions.
Erlangen, BavariaAges 18 years+ - NCT05455619RecruitingPhase 1/Phase 2
Targeted drugs for PI3K-altered, HR+/HER2- breast cancer
This Phase 1/2 trial tests how well a combination of targeted medicines works for advanced or returning HR+/HER2- breast cancer that has a PI3K pathway change (such as PIK3CA, PTEN, or AKT1). It may help by blocking growth signals in the cancer and is especially for people whose cancer has progressed after hormone therapy and a CDK4/6 inhibitor.
Loma Linda, CaliforniaAges 18 years+ - NCT05468034Recruiting
Exercise program for metastatic breast cancer using a phone
This trial studies how a supervised exercise program (with treadmill walking and phone tracking) affects people living with metastatic breast cancer. It may help by improving fitness and day-to-day ability, especially if you’re currently not meeting regular exercise goals.
New Haven, ConnecticutAges 18 years+ - NCT05470348RecruitingPhase 1
Test drug BL-B01D1 for advanced breast and other solid cancers
This Phase 1 trial tests BL-B01D1 in people with advanced (unresectable or metastatic) breast cancer and certain other solid tumors that have not worked with standard treatment. The goal is to learn if the drug can be given safely and to see whether it shows signs of benefit.
Guangzhou, GuangdongAges 18–75 - NCT05475678RecruitingPhase 2
Camrelizumab plus chemo before surgery for triple-negative breast cancer
This Phase 2 trial tests adding camrelizumab (an immune therapy) to standard chemotherapy before surgery for people with triple-negative breast cancer that has not spread. It aims to improve how much the tumor shrinks before and around the time of surgery.
