Jacksonville, FloridaAges 18 years+ - NCT04731610Recruiting
Radiation after thymoma surgery versus watchful waiting
This trial compares two approaches after complete surgical removal of stage IIb or III thymoma: targeted radiation (conformal post-operative radiotherapy) or no further treatment right away (surveillance). It aims to see whether adding radiation lowers the risk of the cancer coming back without causing unacceptable side effects.
CaenAges 18–75 - NCT04722523RecruitingPhase 1
Cemiplimab plus chemo and other immune treatment for head and neck cancer
This Phase 1 trial tests how well cemiplimab (an immune treatment) can work when combined with chemotherapy and an additional immunotherapy for certain head and neck cancers. It may help shrink the cancer and improve outcomes, while also checking safety and dosing.
Basking Ridge, New JerseyAges 18 years+ - NCT04692818Recruiting
3D ultrasound imaging for women with a breast lump
This study tests how well a new 3D ultrasound method can “see” a solid breast lump that is being biopsied. It may help doctors get clearer images to guide diagnosis, especially alongside a standard biopsy.
Rochester, MinnesotaAges 18 years+ - NCT04719156RecruitingPhase 2
Fluorescent dye to check tumor margins during surgery
This Phase 2 study tests whether using a fluorescent dye during tumor surgery can help the surgical team better see where the tumor ends. It may help aim for complete removal and lower the chance of the tumor coming back.
Pittsburgh, PennsylvaniaAges 18–100 - NCT04747054RecruitingPhase 3
Radiation plus pembrolizumab for newly diagnosed metastatic head and neck cancer
This trial studies whether adding pembrolizumab (an immune system medicine) to radiation can improve outcomes in people newly diagnosed with metastatic head and neck squamous cell cancer. It may help the immune system better recognize and fight the cancer alongside radiation.
AvignonAges 18 years+ - NCT04744116RecruitingEarly Phase 1
Cord blood cell therapy added to ruxolitinib for steroid-resistant GVHD
This trial studies whether adding cord-blood–derived cells to ruxolitinib can improve steroid-resistant acute graft-versus-host disease (GVHD) affecting the lower gut or liver. It’s meant for people who are not getting better (or are worsening) despite adequate steroid treatment.
Houston, TexasAges 12–80 - NCT04698785RecruitingPhase 2
Regorafenib to help prevent cancer return after treatment
This Phase 2 study tests whether regorafenib, given after your main treatments, can help keep high-grade bone sarcoma from coming back or progressing. It checks safety and whether this “maintenance” approach works better than best supportive care alone.
BesançonAges 12 years+ - NCT04769206RecruitingPhase 1/Phase 2
Boost nerve signaling to improve blood vessel function
This study tests a treatment aimed at increasing “rest-and-digest” nerve activity to improve how blood vessels work, especially in people with vascular oxidative stress. It is designed for African American adults and looks at whether the intervention can improve blood vessel-related health markers.
Nashville, TennesseeAges 18–60 - NCT04725916Recruiting
Study of water exposure and drain-related risks after certain surgeries
This trial looks at how using water (like showers) affects risks related to surgical drains after specific cosmetic or reconstructive procedures. Your results may help improve post-surgery safety guidance for patients who go home with drains.
Danville, PennsylvaniaAges 18 years+ - NCT04763343RecruitingPhase 3
Ketamine to help prevent repeat suicide attempts in youth
This Phase 3 study tests ketamine to reduce ongoing suicidal thoughts and help prevent another suicide attempt in youth after a recent attempt. It will compare ketamine treatment against standard care to see if it helps improve safety and reduce suicide risk.
Cleveland, OhioAges 14–30 - NCT04715568RecruitingPhase 4
Testing how smoke exposure affects heart health
This study looks at whether being exposed to secondhand tobacco smoke at work affects heart and blood vessel health. It may help researchers understand which people are at higher risk and how the body responds to that exposure.
San Francisco, CaliforniaAges 40 years+ - NCT04740697Recruiting
Complementary therapies to help people stay on tamoxifen
This study looks at whether adding alternative or complementary supports can improve how well people stick with tamoxifen treatment for early hormone-related breast cancer. If it helps adherence, it may help people benefit more reliably from their prescribed therapy.
ToulouseAges 1.5 years+ - NCT04751435Recruiting
Genetic testing education for cancer patients of diverse backgrounds
This study tests new educational materials about genetic testing for cancer patients. It aims to find the best ways to explain genetic testing to people from different backgrounds, especially Black, Latino, and non-Latino non-Black communities.
Brooklyn, New YorkAges 18 years+ - NCT03720860Recruiting
Study inflammatory signals in sudden kidney injury in ICU
This study looks at substances related to inflammation to better understand sudden kidney problems in people who are very sick in the ICU. It may help improve how kidney injury is predicted and treated after severe illness or major events.
Uppsala, Uppsala CountyAges 18 years+ - NCT04701684Recruiting
Fast-stroke treatment workflow study to save minutes to clot removal
This study tests whether a streamlined hospital workflow can reduce the time it takes to reopen blocked blood vessels during very fast stroke treatment. Faster treatment may help more brain tissue be saved by getting endovascular (clot-removal) therapy started sooner.
Jacksonville, FloridaAges 18 years+ - NCT04663399Recruiting
Study immune changes after stroke treatment
This study looks at how the body’s immune system responds after an acute ischemic stroke that may be treated with a procedure called mechanical thrombectomy. It may help doctors understand what immune changes happen after treatment and improve future care.
Paris, ParisAges 18 years+ - NCT04628767RecruitingPhase 2/Phase 3
Durvalumab plus chemo before surgery for upper tract cancer
This trial tests whether adding an immunotherapy drug (durvalumab) to chemotherapy before surgery can improve outcomes for people with high-grade upper tract urothelial cancer. It compares different treatment approaches based on whether a patient can receive cisplatin chemotherapy.
Kingman, ArizonaAges 18 years+ - NCT04671667RecruitingPhase 2
Pembrolizumab vs chemo-radiation after surgery for recurrent head/neck cancer
This trial tests whether pembrolizumab (an immunotherapy drug) works better than the usual chemo plus radiation after surgery for cancer that has come back in the head and neck area. It may help reduce cancer returning or spreading by using your immune system, but eligibility depends on how the cancer came back and your prior treatments.
Birmingham, AlabamaAges 18–79 - NCT04665739RecruitingPhase 2
Lutetium Lu-177 for lung carcinoid tumors with somatostatin receptors
This trial tests lutetium Lu 177 dotatate, a targeted radiation treatment, for advanced lung neuroendocrine (carcinoid) tumors that have a specific marker called somatostatin receptors. It may help shrink tumors by delivering radiation directly to cancer cells that “light up” on a special scan.
Birmingham, AlabamaAges 18 years+ - NCT04654208Recruiting
