Shenyang, LiaoningAges 18–70 - 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+ - NCT05377047Recruiting
Targeted radiation for limited recurrent breast cancer spread
This trial tests whether a precise form of high-dose radiation can control up to 1–5 breast cancer metastases (spread) in a few body areas. It may help by focusing treatment only on visible spots while limiting radiation to the rest of the body.
Gothenburg, Västra GötalandsregionenAges 18 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+ - NCT05406635Recruiting
Imaging vs blood tests to guide heart-safe HER2 treatment
This trial compares whether special heart imaging or blood tests better helps monitor heart safety while you receive HER2-targeted therapy (like trastuzumab, with or without pertuzumab) plus chemotherapy. It may help doctors catch early heart stress and choose the safest treatment plan for you.
AalborgAges 18–90 - 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 - NCT05420454RecruitingPhase 4
Neoadjuvant treatment for breast cancer before surgery
This trial tests a treatment given before breast surgery to shrink breast cancer and improve outcomes based on your tumor type. Your eligibility depends on tumor size/stage, hormone and HER2 markers, and overall health checks.
Hangzhou, ZhejiangAges 18 years+ - NCT05420467RecruitingPhase 4
Trial of add-on breast cancer treatment after surgery
This Phase 4 study tests an additional (adjuvant) treatment for breast cancer after surgery and standard follow-up care. It may help lower the chance the cancer comes back, but you must match specific tumor and body-chemistry requirements to join.
Hangzhou, ZhejiangAges 18 years+ - 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+ - NCT05440227RecruitingPhase 2
PG2 shots to reduce moderate to severe breast cancer fatigue
