Denver, ColoradoAges 18–49 - NCT05741164RecruitingPhase 2
Propranolol plus pembrolizumab for hard-to-treat breast cancer
This Phase 2 trial studies whether adding propranolol to pembrolizumab can “re-sensitize” tumors and slow cancer in triple-negative breast cancer that no longer responds to checkpoint immunotherapy. It may help some people whose cancer has grown despite prior pembrolizumab and chemotherapy.
Atlanta, GeorgiaAges 18 years+ - NCT05743257Recruiting
Study how neighborhood changes affect health behaviors
This study looks at how specific changes in parts of Paris may influence people’s health behaviors. You may be in the study if you live in the intervention area near Porte de la Chapelle or in a nearby area without those changes, and you’re over 18.
CréteilAges 18 years+ - NCT05746793Recruiting
IVF pregnancy study to prevent pre-eclampsia in high-risk women
This trial studies ways to lower the risk of pre-eclampsia (dangerous high blood pressure in pregnancy) in women who are having a first pregnancy through IVF/ICSI or who have PCOS. It’s aimed at people considered higher risk for pre-eclampsia.
BrusselsAges 18–48 - NCT05756569RecruitingPhase 2
Enfortumab plus pembrolizumab for advanced bladder cancer variants
This trial studies enfortumab vedotin plus pembrolizumab (immunotherapy) for people with advanced bladder cancer that has a “variant” or non-urothelial subtype. It aims to shrink tumors and improve outcomes when standard options have not worked or are no longer enough.
Atlanta, GeorgiaAges 18 years+ - NCT05757310RecruitingPhase 1
Stem cell transplant with lower-intensity chemo for severe aplastic anemia
This Phase 1 trial tests a “lower-intensity” chemotherapy plan followed by a stem cell transplant from a related half-match donor for severe aplastic anemia that has returned or did not respond to prior medicines. It aims to see if this approach is safe and works well enough to help your blood counts recover.
Duarte, CaliforniaAges Up to 75 years - NCT05775939Recruiting
PET/CT scan study to track heart damage from cancer radiation
This study uses a special scan (PET/CT) to look for early heart (cardiac) injury caused by radiation treatment for lung or esophageal cancer. If you may be at higher heart risk from your planned radiation dose, the scan may help researchers better measure that damage over time.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05780853Recruiting
Game-based testing for young children’s learning and communication
This trial uses a simple, game-like assessment to better understand how young children develop and learn. It may help by creating or improving tools that track development and identify needs earlier.
LondonAges 3–8 - NCT05800509Recruiting
Program for gestational diabetes and low mood in pregnancy
This study offers an intervention program to help people who are diagnosed with gestational diabetes and may also experience depression during pregnancy. It may help improve health during pregnancy and support mood and well-being with smartphone-based participation.
TaipeiAges 20 years+ - NCT05830058RecruitingPhase 2
PET-guided focused radiation for limited worsening lung, melanoma, kidney cancer
This Phase 2 study tests whether using a PET scan to guide focused radiation (SBRT) can control a small number of cancer spots that are starting to grow despite prior treatment. It may help patients avoid wider radiation by targeting only the limited progressing areas.
Duarte, CaliforniaAges 18 years+ - NCT05835973Recruiting
Study of sleep changes in people with inflammatory bowel disease
This study looks at how sleep patterns change in adults with inflammatory bowel disease (IBD) who are currently in remission. It may help researchers understand sleep issues in IBD and identify ways to improve care during symptom-free periods.
