Check mapping of the first lymph node in high-risk uterine cancer
This trial studies how to find the “sentinel” (first) lymph node during surgery for high-risk endometrial (uterine) cancer. It may help surgeons better tell whether cancer has spread to nearby lymph nodes and guide the extent of lymph node removal.
Curitiba, ParanáAges 18–75 - NCT03368651RecruitingPhase 3
Testing a pre-surgery infusion to improve liver cancer outcomes
This trial tests whether giving medicine directly into the liver blood vessels before surgery can improve survival for people with liver cancer that has a blockage (tumor in the portal vein). It compares this approach plus surgery versus surgery alone in a randomized study.
Guangzhou, GuangdongAges 18–75 - NCT03374215Recruiting
Study hormone causes of high blood pressure in Black adults
This study looks at the body’s hormone signals to understand what causes primary aldosteronism (a condition that can lead to high blood pressure). By comparing clinical results and lab data, researchers hope to improve how the condition is diagnosed and managed, especially in Black participants.
Bethesda, MarylandAges 7–70 - NCT03379909RecruitingPhase 2
Metformin taken by mouth for early bladder cancer
This trial studies whether a diabetes medicine called metformin can help prevent or control non-muscle-invasive bladder cancer inside the bladder. You would take it by mouth, and the study checks safety and whether it works.
Nijmegen, GelderlandAges 18 years+ - NCT03382158Recruiting
Learn about DICER1-related tumors through a patient registry
This registry collects information about people with known or suspected DICER1-related conditions, including certain rare chest and other tumor types. It helps doctors and researchers understand these conditions better and may support future studies.
Minneapolis, MinnesotaAges birth–100 years - NCT03383978RecruitingPhase 1
Test brain injections plus IV antibody for HER2-positive glioblastoma
This early-phase study tests a combination of cells injected directly into the brain and an IV antibody to treat recurrent HER2-positive glioblastoma (or a related tumor, gliosarcoma). It may help by attacking the tumor locally in the brain while the antibody boosts the immune system’s response.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT03383575RecruitingPhase 2
Azacitidine plus enasidenib for IDH2-mutant MDS
This trial tests whether combining azacitidine with enasidenib helps people with myelodysplastic syndrome (MDS) that has an IDH2 mutation. It’s designed for people who are either new to “hypomethylating” treatment or whose MDS returned/worsened after it.
Baltimore, MarylandAges 12 years+ - NCT03385018Recruiting
Laparoscopic total stomach surgery trial for stomach cancer
This trial studies whether a minimally invasive (laparoscopic) removal of the entire stomach, along with lymph node removal, can be done safely and effectively for certain stomach cancers. It may be an option if your cancer is in the stomach, has limited spread to nearby lymph nodes, and can be fully removed.
SeoulAges 20–80 - NCT03385720Recruiting
Saving the submandibular gland during neck surgery
This study looks at whether a specific way of doing neck surgery can help preserve the salivary gland under your jaw in people with early-stage mouth cancer. It may reduce side effects related to saliva, while treating the cancer.
Beijing, Beijing MunicipalityAges Up to 90 years - NCT03392233RecruitingPhase 2
Targeted radiation for spinal metastases causing significant pain
This trial tests a focused form of radiation (stereotactic body radiation) to treat cancer spread to the spine, especially when it causes substantial pain. It may help shrink or control the spinal spots while limiting damage to surrounding tissues.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT03394417Recruiting
StrataXRT skin gel to prevent rash during head and neck radiation
This trial tests whether a medicated skin gel (StrataXRT) can better prevent painful skin rash (“acute dermatitis”) in people with head and neck cancer who receive chemotherapy and radiation at the same time. If you’re eligible, you may get the study skin product and help doctors find a safer, more comfortable way to protect the skin during treatment.
SingaporeAges 21–80 - NCT03396718Recruiting
De-escalating radiation after HPV head and neck cancer surgery
This study looks at whether some people with HPV-positive throat/oropharynx cancer can safely receive a less intense form of radiation (and sometimes chemo) after surgery. It aims to reduce treatment burden while keeping the cancer under control, based on how high-risk the pathology looks.
Tübingen, Baden-WurttembergAges 18 years+ - NCT03398161RecruitingPhase 2
Very low-dose skin radiation for mycosis fungoides spots
This trial tests whether ultra low-dose radiation can control specific skin lesions from mycosis fungoides (a type of lymphoma that affects the skin). It may help shrink or control targeted spots while using a lower radiation amount.
Houston, TexasAges 18 years+ - NCT03401047RecruitingEarly Phase 1
Estradiol patch study for hormone signaling in PCOS
This early-stage study tests whether adding an estrogen skin patch (estradiol) can change how your body releases key reproductive hormones in adults with PCOS. It may help researchers better understand PCOS-related hormone control and signaling.
Charlottesville, VirginiaAges 18–30 - NCT03401294RecruitingPhase 2
Turn unresectable liver cancer into operable colorectal cancer
This Phase 2 study tests a treatment strategy to shrink or control colorectal cancer that has spread only to the liver, with the goal of making it removable by surgery. If you qualify, it may offer a chance to move from “not operable” to “operable,” but it’s still experimental.
Regina, SaskatchewanAges 18–70 - NCT03408964Recruiting
Blood tests to predict treatment response in prostate cancer
This study checks whether certain blood markers can help predict how well people with prostate cancer will respond to therapy. It may help doctors choose the most effective treatment sooner by using information from your blood.
BellinzonaAges 18 years+ - NCT03406247RecruitingPhase 2
Immunotherapy after salvage surgery for head and neck cancer
This Phase 2 trial tests an immunotherapy given after salvage surgery for certain head and neck squamous cell cancers that came back (or a new second cancer) in an area that was already treated with radiation. It aims to lower the chance the cancer returns after surgery, especially in higher-risk situations.
Villejuif, Val De MarneAges 18 years+ - NCT03408353Recruiting
MERIT study uses mammogram and blood tests to assess breast cancer risk
