Alicante, AlicanteAges 18–100 - NCT04957511Recruiting
Testing gut bacteria in gynecologic cancer patients on immunotherapy
This study looks at how gut bacteria may relate to how well immunotherapy works in people with advanced or returning gynecologic cancer. You may be asked to give stool samples several times so researchers can measure changes in your gut microbiome.
Orlando, FloridaAges 18 years+ - NCT04957901Recruiting
Tracking a blood marker in children with lymphoma
This study checks whether measuring a blood test called “circulating tumor DNA” (ctDNA) helps monitor childhood lymphoma during treatment. It’s meant to see if ctDNA tracking can provide useful information alongside standard exams.
GuangzhouAges 1–18 - NCT04959097Recruiting
CHLA retinoblastoma database and tissue study
This study collects medical information and, when available, tissue samples from children with retinoblastoma treated at Children’s Hospital Los Angeles. It may help doctors learn more about the disease and improve future care.
Phoenix, ArizonaAges birth–18 years - NCT04959175RecruitingPhase 1/Phase 2
Lower post-transplant drug doses for older or unfit patients
This trial tests whether giving a lower dose of cyclophosphamide after a bone marrow transplant can be safer for older or medically “unfit” patients, while still helping control blood cancers. It is designed for people who can’t tolerate the usual strongest transplant preparation.
Bethesda, MarylandAges 12–85 - NCT04959604Recruiting
Fluorescent dye mapping to find lymph nodes in colon cancer
This trial studies whether a fluorescent dye used during an exam can help doctors map (find) lymph nodes in colon cancer. It may help improve how surgeons plan treatment and decide what to remove.
HamburgAges 18–100 - NCT04959903RecruitingPhase 1/Phase 2
SMART101 after T-cell–depleted bone marrow transplant for blood cancers
This early-phase study tests SMART101 given after a T-cell–depleted (T-cell removed) donor bone marrow transplant. It aims to see if the treatment is safe and can help control certain high-risk blood cancers in children and adults.
New York, New YorkAges Any age - NCT04960839Recruiting
Preventive radiation to the other breast after breast cancer surgery
This study looks at whether “preventive” radiation to your other (opposite) breast can lower the chance of future breast cancer in people at higher genetic risk. You must have had surgery for early-stage breast cancer and agree to avoid removing the other breast and ovaries.
Jiangxi, JiangxiAges 30–70 - NCT04962672Recruiting
Tested anesthesia approach for survival in high-grade brain tumors
This study checks whether a specific anesthesia plan used during surgery is practical and safe for people having their first operation for a high-grade brain tumor. If it works well, it may help support better outcomes after surgery.
Toronto, OntarioAges 18 years+ - NCT04965077RecruitingPhase 1
First study of MIL97 for advanced solid tumors
This Phase 1 trial tests MIL97, a new treatment, in adults with advanced solid cancers that have come back or cannot be removed. The goal is to find a safe dose and see how the cancer responds.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 18 years+ - NCT04965766RecruitingPhase 2
Study drug for HER2-negative, advanced breast cancer after prior treatment
This Phase 2 trial tests patritumab deruxtecan (U3-1402) in people with HER2-negative, hormone-receptor positive (HR+) breast cancer that cannot be removed by surgery or has spread. It’s for cancers that have progressed despite endocrine therapy plus a CDK4/6 inhibitor, aiming to shrink tumors and control the disease.
DijonAges 18 years+ - NCT04966663RecruitingPhase 2
Using blood DNA tests to guide lung cancer treatment
This study uses a blood test called ctDNA to look for leftover lung cancer after surgery. Based on that result, the trial will help decide which treatment approach is best for you and may catch cancer returning earlier.
Toronto, OntarioAges 18 years+ - NCT04967976Recruiting
Breast mesh in two-step breast reconstruction after cancer
This trial studies whether using a supportive “mesh” during a two-stage breast reconstruction surgery is safe and effective for people rebuilding their breast after breast cancer. You might be a candidate if you have no signs of spread to distant organs and meet several health and body-size criteria.
Houston, TexasAges 18–70 - NCT04968288Recruiting
Study of the natural course of KSHV-related Castleman disease
This study looks at how KSHV-associated multicentric Castleman disease naturally progresses over time, without necessarily testing a new treatment. It may help doctors better understand the disease and what changes to watch for, which could guide future care.
Bethesda, MarylandAges 18 years+ - NCT04968990RecruitingPhase 2
New Wilms tumor treated with proton beam abdominal radiation
This trial studies a specific type of radiation (proton beam) given to the abdomen after surgery and/or chemotherapy in children and young people with newly diagnosed Wilms tumor. The goal is to improve cancer control while carefully targeting radiation to the right stage of disease.
Memphis, TennesseeAges Any age - NCT04969926Recruiting
Study of parathyroid problems in children and adults
This is an observational study that follows people who have or may develop parathyroid-related conditions. The goal is to better understand how these problems change over time and what patterns show up, which can help improve future care.
Bethesda, MarylandAges 6 months–100 years - NCT04969315RecruitingPhase 1/Phase 2
Drug TT-10 and TT-4 for advanced solid tumors
This early-phase trial tests two investigational drugs—TT-10 and TT-4—alone and together in people with advanced solid cancers. The study is designed to find safe doses and see if the treatment can shrink tumors or slow cancer growth.
Los Angeles, CaliforniaAges 18 years+ - NCT04969731RecruitingPhase 3
Immune cell therapy plus gemcitabine after pancreas surgery
This Phase 3 trial tests whether adding an immune cell therapy (Immuncell-LC) to the standard chemotherapy drug gemcitabine helps people with resectable pancreatic cancer after surgery. It aims to improve safety and outcomes like preventing the cancer from coming back.
Seoul, Daehak-ro, Jongno-guAges 19–80 - NCT04969835RecruitingPhase 1
Safety and early response study of AVA6000 for solid tumors
This Phase 1 study tests AVA6000 in people with certain solid tumor cancers, mainly to check safety and how the body processes the drug. It also looks for early signs of tumor response to see if it might help further in later studies.
New York, New YorkAges 18 years+ - NCT04970056Recruiting
Pancreatic cancer risk and early-detection registry study
This study builds a database of people at higher risk for pancreatic cancer (or certain early warning findings) to help find better ways to detect the disease early. You may be asked to complete health questionnaires and possibly donate a blood/saliva/swab sample.
Phoenix, ArizonaAges 18–90 - NCT04970472Recruiting
Urothelial bladder cancer sample collection for adults
This trial collects clinical samples from adults who have suspected or confirmed urothelial (bladder/urinary tract lining) cancer. It helps researchers study the disease and may support future improvements in diagnosis or treatment.
ToulouseAges 18–99 - NCT04974346RecruitingPhase 3
Radiation to prevent spread in cervical cancer lymph nodes
This Phase 3 trial tests whether adding a preventive radiation treatment to lymph node areas near the abdomen helps stop cervical cancer from spreading. It aims to improve outcomes for people with certain cervical cancer stages and lymph node results on PET-CT.
Hangzhou, ZhejiangAges 18–75 - NCT04972942RecruitingPhase 1
Immunotherapy for high-risk T-cell blood cancers after transplant
This Phase 1 study tests a targeted immune treatment given after strong pre-treatment (myeloablative chemo plus total-body radiation) before or along with an allogeneic stem cell transplant. It may help prevent the cancer from coming back in young people with high-risk T-cell ALL or certain T-cell lymphomas.
