Utrecht, UtrechtAges 18 years+ - NCT06519734Recruiting
Immune Deficiency, IUDs and Menstrual Products Study
This study looks at how well women with primary immune deficiencies can use intrauterine devices (IUDs) and other menstrual products. It aims to help doctors and patients make better choices for safe and effective period care.
ParisAges 18 years+ - NCT06519487Enrolling by invitation
How social experiences affect immune cells
This study looks at how social experiences and background may influence immune cell activity. It could help understand why some groups have different health outcomes.
Baltimore, MarylandAges 18 years+ - NCT06514898RecruitingPhase 1
Personalized cell therapy for recurrent medulloblastoma
This trial tests a combination of personalized immune cells, vaccines, stem cells, and an immunotherapy drug (pembrolizumab) for children and young adults whose medulloblastoma has come back or grown. The goal is to help the immune system fight the cancer more effectively.
Washington D.C., District of ColumbiaAges 4–30 - NCT06502691RecruitingPhase 1/Phase 2
New imaging test to measure PARP in metastatic breast cancer
This trial tests a new imaging scan called [18F]FTT PET that may show how much of a protein called PARP is in your tumors. This could help doctors decide if a PARP inhibitor (a type of targeted therapy) is right for you. You may be able to join if you have metastatic breast cancer and are already planning to take a PARP inhibitor.
Seattle, WashingtonAges 18 years+ - NCT06489964Recruiting
Paying for unfunded vaccines at your pharmacy
This trial tests a way for you to get vaccines that are recommended but not free, like FluMist for kids, Shingrix for shingles, or RSV vaccines. You pay a copayment at a participating pharmacy instead of the full price.
Halifax, Nova ScotiaAges 2 years+ - NCT06484686Enrolling by invitationPhase 4
