Birmingham, AlabamaAges 18–75 - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.
Nanchang, JiangxiAges 18–75 - NCT06878625RecruitingPhase 2
Trop-2 drug combo for advanced triple-negative breast cancer
This trial tests a new drug combination (Trop-2 antibody-drug conjugate plus other therapies) for advanced triple-negative breast cancer that has spread or come back. It may offer a new option for people who have had only 1–2 prior chemotherapies and have not used immunotherapy or anti-angiogenic drugs before.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT07406789RecruitingPhase 2
Personalized diet study for women with advanced breast or gynecologic cancer
This study tests whether a personalized dietary plan can help manage side effects and improve well-being in women with advanced breast or gynecologic cancer who are receiving antibody-drug conjugate (ADC) therapy. ADCs are a type of targeted cancer treatment that delivers chemotherapy directly to cancer cells.
Madrid, MadridAges 18 years+ - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT07525869Recruiting
Pegfilgrastim to prevent low white blood cells in triple-negative breast cancer
This study tests whether a medicine called pegfilgrastim can help prevent dangerously low white blood cell counts in women with triple-negative breast cancer receiving a specific chemotherapy combination. Low white blood cells increase infection risk, so this medicine may help patients stay safer during treatment.
Seoul, Seodaemun-guAges 19–70 - 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+ - NCT06977893RecruitingPhase 3
Chemo and immunotherapy for HR+ breast cancer before surgery
This trial tests whether adding the immunotherapy drug toripalimab to chemotherapy before surgery helps women with a certain type of breast cancer (HR+, HER2-). It aims to see if this combination works better than chemotherapy alone.
HangzhouAges 18–75 - NCT07087860RecruitingPhase 2
Plasma exchange plus targeted therapy for advanced bladder cancer
This trial tests a procedure called therapeutic plasma exchange (TPE) combined with the drugs enfortumab vedotin and pembrolizumab for people with advanced bladder cancer that has stopped responding to standard treatments. The goal is to see if TPE helps the drugs work better.
Rochester, MinnesotaAges 18 years+ - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
This trial tests a cancer antibody-drug combination plus pembrolizumab (immunotherapy) versus standard treatment. It’s for people with triple-negative breast cancer that still has invasive disease in the breast or lymph nodes after surgery and chemotherapy before surgery.
Birmingham, AlabamaAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Duarte, CaliforniaAges 18–75 - NCT05981014RecruitingPhase 1/Phase 2
Immune cells from lymph nodes for HER2-negative breast cancer
This trial tests whether taking immune cells from your lymph nodes and giving them back to you can help shrink breast cancer that has not responded fully to initial chemotherapy. It is for women with HER2-negative breast cancer who have had stable disease after two cycles of a standard chemotherapy combination.
Guangzhou, GuangdongAges 18–70 - NCT05981001RecruitingPhase 1/Phase 2
Experimental cell therapy for advanced HER2-negative breast cancer
This study tests a new treatment for advanced HER2-negative breast cancer. Doctors will take immune cells from lymph nodes near your tumor, grow them in a lab, and then give them back to you along with chemotherapy and immunotherapy. This approach aims to help your body fight the cancer more effectively.
Guangzhou, GuangdongAges 18–70 - NCT06121570RecruitingPhase 1
Study of immune cells from lymph nodes for HER2-negative breast cancer
This trial tests whether using a patient's own immune cells from lymph nodes near the tumor, given as a treatment before surgery, can help shrink HER2-negative breast cancer. It is for people whose cancer has not responded fully to two cycles of initial chemotherapy.
Guangzhou, GuangdongAges 18–70 - NCT06121557RecruitingPhase 1
Immune cells from lymph nodes for advanced HER2-negative breast cancer
This trial tests a treatment using your own immune cells taken from lymph nodes near the tumor. The cells are grown in a lab and given back to you to fight cancer, along with another drug chosen by your doctor.
Guangzhou, GuangdongAges 18–70 - NCT06234137Recruiting
Chemo plus targeted therapy for advanced HER2+ breast cancer
This trial tests a combination of chemotherapy (docetaxel and carboplatin) plus two targeted drugs (Inetetamab and Pyrotinib) for people with locally advanced HER2-positive breast cancer that has not spread to other parts of the body. The goal is to see if this powerful combo can shrink the tumor before surgery or other treatments.
Wenzhou, ZhejiangAges 18–75 - NCT06671262RecruitingPhase 2
Immunotherapy plus radiation before breast cancer surgery
This trial tests combining two treatments—an immunotherapy drug (Toripalimab) and radiation—before surgery for a certain type of breast cancer (HR+, HER2-negative) that has spread to lymph nodes. The goal is to see if this combination helps shrink the tumor more than standard therapy alone.
Hangzhou, ZhejiangAges 18–85 - NCT06266312Recruiting
Lifestyle program before breast cancer surgery
This study tests whether a program of healthy eating, exercise, and stress management before breast cancer surgery is practical and helpful for patients who will receive chemotherapy first. It aims to see if a lifestyle plan can improve your well-being during treatment.
Maastricht, LimburgAges 18 years+ - NCT07287098RecruitingPhase 2
Imlunestrant for premenopausal women with ER+/HER2- early breast cancer
This trial tests a new hormone-blocking pill (imlunestrant) in premenopausal women with early-stage ER+/HER2- breast cancer. Depending on whether you've had prior hormone therapy, the study will see if this treatment works better than standard options.
Birmingham, AlabamaAges 18 years+ - NCT06956690RecruitingPhase 1/Phase 2
Testing HMBD-501 for HER3-positive advanced solid tumors
This trial tests a new drug, HMBD-501, for people with advanced solid tumors that have a specific protein called HER3. The goal is to see if the drug is safe and if it can help shrink or control the cancer.
La Jolla, CaliforniaAges 18 years+ - NCT06672302Recruiting
