Canakinumab shot for lower-risk MDS and related blood disorders
This trial tests canakinumab, a medication that blocks inflammation, given as a skin (subcutaneous) injection. It is for adults with lower-risk myelodysplastic syndromes (MDS) or a related condition (chronic myelomonocytic leukemia or CCUS) to see if it can improve blood counts and reduce problems like anemia or transfusion needs.
Houston, TexasAges 18 years+ - NCT04240054RecruitingPhase 2
Study drugs before transplant for myeloma with kidney problems
This Phase 2 trial tests whether a combination of anti-myeloma medicines given before stem cell transplant works well and is safe for people with multiple myeloma who also have kidney problems. It may help control the myeloma and prepare you for the transplant.
Milwaukee, WisconsinAges 18 years+ - NCT04241328Recruiting
Cardiac surgery registry for patients who used a Medtronic device
This study tracks patients who had cardiac surgery using a specific Medtronic heart-surgery device. It mainly collects real-world data to help understand outcomes, and you may be included if you give consent and are not in another device/drug study that could affect the results.
ViennaAges Any age - NCT04240834RecruitingPhase 4
Low-dose ticagrelor vs aspirin after heart stent placement
This study compares ticagrelor taken at a lower dose versus regular aspirin to help prevent future heart attacks in people who recently had a stent placed after acute coronary syndrome. You may qualify if you’re considered “high risk” for new blockages or clots and can take dual anti-platelet therapy for 12 months.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04246437RecruitingPhase 1
Brain imaging study for autonomic failure with possible Parkinson disease
This Phase 1 study uses a special injected imaging tracer and an MRI scan to look at brain function in people with autonomic failure. It may help researchers understand what’s happening in conditions that can be related to Parkinson disease, multiple system atrophy, or dementia with Lewy bodies.
Nashville, TennesseeAges 18 years+ - NCT04249154RecruitingPhase 2
After prostate surgery, test radiation plus hormone shots
This trial studies whether giving a shorter-course radiation plan after prostate surgery, along with hormone shots (LHRH), can improve outcomes for people with higher-risk prostate cancer. You may be eligible if your PSA (a blood marker) is either still low but high-risk by pathology, or it has started to rise again after surgery.
Montreal, QuebecAges 18 years+ - NCT04250493Recruiting
Testing insulin resistance in multiple system atrophy
This study looks at how the body handles blood sugar (insulin resistance) in people with multiple system atrophy (MSA). Results may help doctors understand the disease better and explore new ways to monitor or treat it.
