Charlottesville, VirginiaAges 18 years+ - NCT05332561RecruitingPhase 2
Personalized treatment after surgery for early breast cancer
This Phase 2 study checks whether adding a personalized (biomarker-matched) medicine after standard chemotherapy and surgery lowers the risk of breast cancer coming back. Your study drug choice depends on tumor test results (from your tumor’s genetics and immune markers).
Heidelberg, Baden-WurttembergAges 18 years+ - NCT05345860Recruiting
Using MRD results to guide extra treatment after breast surgery
This trial checks “MRD” (tiny leftover cancer signals after surgery) to help decide the best additional treatment for early-stage breast cancer. It may help tailor therapy so you get the most useful medicines while avoiding unnecessary treatment.
Beijing, Beijing MunicipalityAges 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+ - 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+ - NCT05408845RecruitingPhase 2
Study drug vs standard care for HER2 salivary gland cancer
This Phase 2 trial tests how well ado-trastuzumab emtansine (and compares to two standard treatment options) works for salivary gland cancers that are HER2-positive or HER2-low. It aims to see whether the study drug can control cancer better and with acceptable side effects.
Birmingham, AlabamaAges 18 years+ - NCT05415709RecruitingEarly Phase 1
Cisplatin heated during surgery or before surgery for advanced ovarian cancer
This early-phase study tests whether giving cisplatin (a chemotherapy drug) heated in the abdomen during surgery—or giving cisplatin before surgery—can improve treatment for stage III or IV ovarian, fallopian tube, or peritoneal cancer. It’s designed for people who are having surgery after several cycles of standard chemotherapy and may benefit from a better cancer-killing approach at the time of tumor removal.
Columbus, OhioAges 18 years+ - 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+ - NCT05487846Recruiting
Peer support during genetic testing for metastatic prostate cancer
This trial offers support from a trained peer to help African American men understand and go through genetic testing for prostate cancer. It may help you feel less overwhelmed and better prepared during the testing and decision-making process.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05502523Recruiting
