Sentinel lymph node mapping to reduce leg swelling after surgery
This study tests whether a special way of finding lymph nodes during hysterectomy can lower the risk of long-term leg swelling or related dysfunction in people with stage I endometrial cancer. It compares standard lymph node assessment with sentinel lymph node mapping and looks at how this affects day-to-day leg functioning.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05576974RecruitingPhase 2
Test a dye used during surgery to find head and neck cancer
This trial tests whether a single dose of an imaging dye (given during surgery) can help doctors find the unknown origin of head and neck cancer and check safety. It may help guide surgery and biopsies when the primary cancer location hasn’t been identified.
Dallas, TexasAges 18–99 - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT05547607Recruiting
Study of heart valve infection signs on heart scans
This study looks at clinical symptoms and test findings to better understand heart valve infection (endocarditis) in adults. It may help doctors recognize the condition sooner and interpret echocardiography results more accurately.
Cona, FerraraAges 18 years+ - NCT05530759Recruiting
Testing blood and tumor samples for diagnostic cancer markers
This study looks at blood and tumor tissue to find signs (markers) that can help diagnose or better understand metastatic cancer. You may be able to join if you’re getting surgery or a biopsy to remove a tumor and there’s a safe way to collect samples.
Rochester, MinnesotaAges 18 years+ - NCT05452941Recruiting
Pneumonia vaccine study for hospitalized adults 65 and older
This study tests a pneumococcal vaccine designed for 20 types of bacteria in older adults who are hospitalized with suspected community-acquired pneumonia. It aims to see how the vaccine works in real-world care and whether it affects how pneumonia happens or progresses.
El Centro, CaliforniaAges 65 years+ - NCT02660645Recruiting
Blue light bladder scan for suspected bladder cancer
This trial uses a special blue-light camera during a bladder procedure to help doctors better see non-muscle-invasive bladder cancer. It may help find cancer spots more clearly so they can be treated sooner.
Birmingham, AlabamaAges 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+ - NCT05326750Recruiting
Brain stimulation to help diagnose and manage memory conditions
This trial studies a non-invasive brain-stimulation approach to help doctors assess and manage certain brain-related conditions. You might benefit by contributing to better diagnostic tools and treatment planning for memory and thinking problems.
KuopioAges 18 years+ - NCT05283421Recruiting
Improving tests for abnormal cervical cells after menopause
This trial is looking at better ways to diagnose changes in the cervix in women after menopause. It may help by improving how doctors decide which cervical abnormalities need attention and follow-up.
RandersAges 50 years+ - NCT05217940Recruiting
Screening women with prior HPV for anal abnormalities
This study looks for early anal cell changes in women who have had high-grade HPV-related problems in the cervix, vagina, or vulva. It may help find concerning changes sooner, using a structured screening exam.
