Imaging test to map tumors in cancers on PD-1 therapy
This Phase 1 study tests a special imaging medicine to see how tumors and immune activity respond when you’re treated with cemiplimab (a PD-1 immunotherapy). It may help doctors better understand who benefits from PD-1 treatment by tracking where the medicine goes in the body.
GroningenAges 18 years+ - NCT05283330RecruitingPhase 1
Tested 212Pb imaging drug for certain advanced GRPR tumors
This early-phase study tests how safe and tolerable an experimental radiation drug is for adults with certain advanced or metastatic cancers that show a target called GRPR. Doctors will also use special scans to confirm the tumor has the target so the treatment can be delivered to the right place.
Chicago, IllinoisAges 18 years+ - NCT04826744Recruiting
Atopic dermatitis study tracking eyelid involvement
This study looks at how often the eyelids are affected in adults with atopic dermatitis (a long-term skin condition). It may help doctors better understand patterns of skin and eyelid symptoms so care can be improved.
LilleAges 18 years+ - NCT05105152RecruitingPhase 1
CAR T cell therapy for kids with CD33 AML that came back
This Phase 1 study tests a type of lab-made immune cell therapy (CAR T cells) made from your T cells to treat AML that has relapsed or not responded, as long as the cancer shows a marker called CD33. The goal is to see if the treatment is safe and can help control AML after it returns or resists standard therapy.
Seattle, WashingtonAges Up to 30 years - NCT05237986Recruiting
Study brain and thinking effects after CAR T therapy in youth
This study looks at how CAR T-cell treatment affects thinking, learning, and day-to-day brain function in children and young adults with certain blood cancers. You (and a caregiver) may complete online testing so researchers can track these changes over time and whether support is needed.
Los Angeles, CaliforniaAges 5 years+ - NCT05248230RecruitingPhase 2
Study drug for adults with cystic fibrosis lung disease
This Phase 2 trial tests 4D-710 to improve lung health in adults with cystic fibrosis who either cannot take CFTR modulator medicines or are not doing well enough on them. You may be eligible if you have moderate lung function and stable oxygen levels, and you meet other safety and health requirements.
Birmingham, AlabamaAges 18 years+ - NCT05207085RecruitingPhase 2
