Recruiting studies near St. Louis
- NCT05483010RecruitingPhase 2
Testing statins to treat low-risk blood disorders with abnormal blood counts
This Phase 2 trial studies whether a statin medicine can help people with CCUS (a bone-marrow condition with abnormal genetic mutations) or lower-risk MDS (a blood disorder) that causes persistent low blood counts. It aims to see if statins can improve blood-related outcomes while keeping you safe from side effects.

ACI-24.060 study for early Alzheimer’s in adults and Down syndrome
This Phase 1/2 study tests an Alzheimer’s treatment called ACI-24.060 to see if it affects the disease in people with early Alzheimer’s changes. It includes two groups: older adults with early symptoms and people with Down syndrome who also show Alzheimer’s-related changes on brain scans.

Whole-genome testing added to standard testing for MDS
This study checks whether adding whole-genome sequencing (a deeper look at DNA) alongside standard genomic tests helps in evaluating myelodysplastic syndrome (MDS). It aims to see if this extra testing is useful and acceptable during routine care—especially for people newly being worked up for MDS.

Rett syndrome genetic registry for MECP2 changes
This trial is a registry that collects health and genetic information from people with Rett syndrome. It may help researchers better understand how MECP2 loss-of-function changes lead to symptoms and how to support patients.
St Louis, MissouriAges birth–99 years - NCT06008808RecruitingPhase 1
Ruxolitinib and abatacept to prevent GVHD after haplo transplant
This trial tests whether a drug called ruxolitinib, with or without another drug called abatacept, can prevent graft-versus-host disease and cytokine release syndrome after a half-matched stem cell transplant from a family donor. It's for people with certain blood cancers who are getting this type of transplant.
St Louis, MissouriAges 18 years+ - NCT05918861RecruitingPhase 3
Tested heart-risk drug for people with recent heart-attack genetics
This trial studies whether dalcetrapib can lower future heart and blood-vessel risk in people who recently had an ACS (acute coronary syndrome, often a heart attack or unstable chest pain) and have a specific genetic marker. It may help people like you by targeting a risk pathway related to that genetic background.
St Louis, MissouriAges 45 years+ - NCT06806033RecruitingPhase 2
New drug combo for relapsed aggressive B-cell lymphoma
This trial tests a new combination of drugs (glofitamab plus gemcitabine and oxaliplatin) for people with aggressive B-cell lymphoma that has returned or not responded to prior treatment. The goal is to see if this approach can improve outcomes while managing side effects.
Swansea, IllinoisAges 18 years+ - NCT07519395RecruitingPhase 2
Camlipixant for abdominal symptoms in IBS-D and IBS-M
This study tests whether a new drug called camlipixant can reduce belly pain and other uncomfortable symptoms in people with irritable bowel syndrome that causes diarrhea or mixed symptoms. The trial compares camlipixant to a placebo (inactive pill) to see if it works better.
Hazelwood, MissouriAges 18–80 - NCT06078553Recruiting
Natural history study of congenital myasthenic syndromes (CMS)
This study follows people with congenital myasthenic syndrome (CMS) caused by changes in certain genes (DOK7, MUSK, AGRN, or LRP4) over time. It does not test any new drug, but helps researchers understand how the condition changes and how to plan future treatments.

What taking part in a down syndrome study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
