Taipei, TaiwanAges 14 years+ - NCT05326308Recruiting
Zanubrutinib treatment in several blood cancers
This non-interventional study looks at outcomes for people with certain slow-growing blood cancers who are treated with zanubrutinib, with specific add-on use of obinutuzumab for follicular lymphoma. It may help doctors understand how this treatment is working in real-world care across several cancer types.
SalzburgAges 18 years+ - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT05326620Recruiting
Renal cancer patients join a Dutch research kidney study
This study enrolls people newly diagnosed with kidney cancer (including when it has spread) to help build research resources for future kidney cancer care. If you qualify, your information may be used to better understand outcomes and improve treatments.
Amsterdam, North HollandAges 18 years+ - NCT05326919Recruiting
Study biobank for people newly diagnosed with certain blood cancers
This study follows people who are newly diagnosed (and haven’t been fully treated yet) with specific leukemia or related blood disorders to help researchers learn which treatments may work best. It may help by connecting you to a larger “precision medicine” patient group for future research.
BobignyAges Any age - NCT05327517Recruiting
Surgery or chemo-radiation for cervical esophagus cancer
This study compares two ways to treat cervical esophagus squamous cell cancer: surgery alone versus chemo-radiation (chemotherapy plus radiation). It may help find the best approach to control the cancer while keeping side effects manageable.
BeijingAges 18–75 - NCT05327686RecruitingPhase 2
Adding focused radiation to immunotherapy for kidney cancer
This Phase 2 trial studies whether adding focused, high-precision radiation to immunotherapy helps people with advanced kidney cancer (that cannot be removed by surgery or has spread). It aims to improve cancer control by combining two treatment approaches.
Birmingham, AlabamaAges 18 years+ - NCT05327543Recruiting
Online yoga program for better quality of life
This study tests whether doing online yoga can improve quality of life in people with non-metastatic breast cancer. It’s meant to help with day-to-day well-being after cancer treatment.
Berlin, State of BerlinAges 18–75 - NCT05327647RecruitingPhase 2
Bicalutamide with BCG for bladder cancer after BCG treatment
This trial studies whether bicalutamide can improve outcomes for people with non-muscle-invasive bladder cancer who are starting BCG through the bladder. It may help prevent cancer from coming back or progressing after BCG.
London, OntarioAges 18 years+ - NCT05328258RecruitingPhase 3
Triptorelin to help protect fertility during cancer chemotherapy
This Phase 3 study tests whether a hormone medicine called triptorelin (a GnRH “fertility-protecting” medicine) can better protect ovarian function while you receive chemotherapy. The goal is to help preserve fertility and reduce the risk of early ovarian failure from cancer treatment.
GothenburgAges 14–42 - NCT05328024Recruiting
Testing who benefits from anti–PD-1 immunotherapy in head cancer
This study looks for signs in your tumor that can predict how well anti–PD-1 immunotherapy will work for certain head and neck cancers. You may benefit by helping doctors match the right treatment to the right patients.
Strasbourg, FranceAges 18 years+ - NCT05329532RecruitingPhase 1/Phase 2
Modi-1 cancer vaccine for several hard-to-treat cancers
This Phase 1/2 study tests a cancer vaccine called Modi-1 Moditope in people with advanced triple-negative breast cancer, head and neck cancer, ovarian/high-grade serous cancer, or kidney cancer. It aims to help the immune system better recognize and attack the cancer.
Brighton, DefaultAges 18 years+ - NCT05328505Recruiting
Imaging-guided radiation for prostate cancer that came back
This trial tests whether a special scan (PSMA PET) can help doctors aim and adjust radiation more precisely when prostate cancer returns after surgery. It may help by increasing dose to areas that look involved while lowering dose to uninvolved pelvic areas.
London, OntarioAges 18 years+ - NCT05331066Recruiting
Tracking side effects from immunotherapy using multiple tests
This study looks at how side effects happen in people receiving immune checkpoint inhibitor immunotherapy for solid cancers. It uses multiple types of tests to better understand these toxicities and may help improve safety and care in the future.
Chelsea, LondonAges 18 years+ - NCT05331105RecruitingPhase 2
Drug for adults with NF1 and non-surgically treatable nerve tumors
This Phase 2 trial tests HL-085 in adults with neurofibromatosis type 1 (NF1) who have a nerve tumor (plexiform neurofibroma) that cannot be removed by surgery and causes symptoms. It aims to shrink or control the tumor by measuring changes on MRI and monitoring side effects.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05331911RecruitingPhase 4
Propofol anesthesia vs sevoflurane for liver tumor surgery
This study compares two types of general anesthesia—propofol-based total intravenous anesthesia versus sevoflurane inhaled anesthesia—during planned surgery to remove liver tumors. The goal is to see whether the anesthesia choice affects long-term outcomes after partial liver removal for hepatocellular carcinoma.
Kaohsiung CityAges 20–80 - NCT05331521RecruitingPhase 3
Study to improve brain function in newly diagnosed glioma patients
This Phase 3 study tests a treatment plan after surgery to improve brain function and quality of life in adults with newly diagnosed, specific types of brain tumors (gliomas). It may help you keep thinking clearly and living better while your tumor is treated with standard medicines.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT05332002RecruitingPhase 2
Study chemotherapy plus immunotherapy for HER2-negative esophageal cancer
This Phase 2 trial tests a combination treatment called sFOLFOXIRI for advanced esophageal or stomach-area cancer that is HER2-negative. It aims to see how well the treatment works and whether it is safe for people who have not had standard chemotherapy for this metastatic cancer yet.
Hamilton, New JerseyAges 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+ - NCT05332925Recruiting
Tumor samples grown in dishes to predict immunotherapy response
This study takes small biopsy samples of your lung cancer and grows them in a dish to predict how well immunotherapy will work. If you qualify, you’ll receive standard immunotherapy (anti-PD-1/L1, with or without anti-CTLA-4), and the results from the dish-grown tumors will be compared to your real-world response.
Fairway, KansasAges 18–110 - NCT05333367Recruiting
Study of how a light treatment causes immune cell death
This trial looks at how “extracorporeal photochemotherapy” (a light-based treatment done outside the body) works at the cellular level. It may help improve treatment and control for people dealing with immune reactions after transplant or certain blood/skin conditions.
BesançonAges 18–85 - NCT05333302RecruitingPhase 1
CAR-T treatment study for children and young adults with CD19 leukemia
This Phase 1 study tests a CAR-T cell treatment made to target CD19 in children and young adults whose leukemia or lymphoma has come back or did not respond to prior treatment. It aims to see how the treatment works and how safe it is in this age group.
Minsk, Minsk OblastAges 1–30 - NCT05333328RecruitingPhase 4
Test of ovarian function suppression for low-risk premenopausal node+ breast cancer
This trial studies whether ovarian function suppression (a treatment that lowers hormone production from the ovaries) helps women with hormone-receptor positive, HER2-negative breast cancer that has spread to lymph nodes, but who have a low-risk result on a genomic test. It may help reduce breast cancer recurrence while avoiding more intensive treatment for those who are lower risk.
Seoul, KoreaAges 20–50 - NCT05333523RecruitingPhase 3
Personalized neck radiation using a lymph node sentinel biopsy
This Phase 3 trial tests whether guiding neck radiation by checking the “sentinel” lymph node can target treatment more precisely in certain larynx, hypopharynx, or oropharynx cancers. It aims to improve control while potentially reducing unnecessary radiation to areas that don’t need it.
