Stop maintenance medicine in multiple myeloma with low remaining disease
This early-phase study looks at whether it’s safe to stop the usual “maintenance” medicine after a strong response in multiple myeloma. It aims to see if stopping treatment for people with very low remaining disease reduces drug exposure without allowing relapse too soon.
Chicago, IllinoisAges 18 years+ - NCT05293769Recruiting
Food diary questionnaire test for IBS and activity levels
This study checks whether a food questionnaire can reliably estimate what you eat, including certain carbs that can affect digestion (FODMAPs). It also looks at how the results relate to IBS symptoms and your self-reported physical activity.
Jette, Brussels CapitalAges 18–65 - NCT05403151Recruiting
Healthy blood vessel and control study
This study looks at healthy adults and how their blood vessels work. It may help researchers understand normal circulation so they can better compare changes in future conditions.
Bethesda, MarylandAges 18–90 - NCT05398809RecruitingPhase 2
Ruxolitinib for hair regrowth in APECED-related alopecia areata
This Phase 2 study tests ruxolitinib to see if it safely helps regrow hair in people whose alopecia areata is linked to APECED (a rare immune condition). You may qualify if you have significant scalp hair loss for at least 6 months and haven’t had regrowth with other treatments.
Bethesda, MarylandAges 12–75 - NCT05413291Recruiting
Study of movement disorders over time
This study follows people (or family members of people) who have or might have a movement disorder to better understand how symptoms change over time. You may be asked to attend study visits and complete study procedures for the duration of the study.
Bethesda, MarylandAges 2–100 - NCT05383742RecruitingPhase 2
Compare 6- vs 9-month treatment for tuberculous meningitis
This Phase 2 study tests whether a shorter, stronger 6-month set of medicines works as well as the usual 9-month regimen for tuberculous meningitis (TB infection in the covering of the brain/spinal cord). The goal is to improve outcomes while reducing treatment time and exposure.
Porto AlegreAges 15 years+ - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT05413850RecruitingPhase 1/Phase 2
Lu-177 PSMA drug study for advanced prostate cancer
