Checking RNA markers in blood and muscle in muscle disease
This study looks for tiny RNA “signals” in blood (and sometimes urine) and compares them with muscle samples in people with myotonic dystrophy (DM1 or DM2) and healthy controls. The goal is to find biomarkers that may help track the disease over time.
Boston, MassachusettsAges 5 years+ - NCT05019625Recruiting
Study samples for biomarkers in myotonic dystrophy
This study collects blood and, for some people, muscle tissue to look for signs (biomarkers) that can help track and better understand myotonic dystrophy. You may help by providing samples and basic muscle function testing, depending on your age and condition type.
Boston, MassachusettsAges 5 years+ - NCT05020574RecruitingPhase 2
Study how the microbiome may affect breast implant infections
This Phase 2 study looks at whether changes in the body’s “microbiome” (the normal germs in and on the body) are linked to infections after breast surgery with implants. It may help doctors better predict and prevent implant infections in people undergoing mastectomy with immediate implant placement.
San Francisco, CaliforniaAges 18 years+ - NCT05023772Recruiting
Laser and targeted radiation for spine metastases
This trial tests a combination treatment that uses a laser and focused radiation to shrink tumors in the spine and help stabilize the area near the spinal cord. It’s meant for adults with certain types of solid cancers that have limited spread in the spine and who are not good candidates for surgery.
Detroit, MichiganAges 18 years+ - NCT05029336RecruitingPhase 2
Stem cell transplant using your own cells for autoimmune disease
This Phase 2 study tests an autologous stem cell transplant (a treatment using your own blood-forming stem cells) for severe systemic sclerosis or severe lupus. The goal is to reset the immune system to help control the autoimmune disease.
Philadelphia, PennsylvaniaAges 8–25 - NCT05029726RecruitingPhase 4
Numbing medicine during back surgery to reduce pain
This trial tests a regional anesthesia (numbing medicine given near nerves) during minimally invasive lumbar spine surgery. The goal is to see if it helps control pain around surgery and improves recovery comfort.
Chicago, IllinoisAges 18–80 - NCT05030818RecruitingPhase 4
Study of heart risk changes using a daily polypill
This trial looks at how a daily “polypill” affects coronary (heart blood vessel) risk factors in adults who already take this polypill for prevention after a prior heart event. If you’re eligible, you’ll complete several study visits so the team can compare risk factors over time.
Gijón, Principality of AsturiasAges 18 years+ - NCT05030337Recruiting
Closed-loop oxygen control for very preterm babies on ventilators
This trial tests a computer-guided (“closed-loop”) oxygen control system for very preterm babies who need breathing support. It aims to keep oxygen levels safer and more consistent than standard care.
LondonAges Any age - NCT05031897RecruitingPhase 2
Haplo transplant with reduced donor mismatch and radiation
This trial tests a special bone marrow/stem cell transplant approach using a partially matched family donor, along with conditioning treatment that involves radiation. It aims to help treat certain blood cancers by replacing damaged blood-forming cells with new ones from the donor.
Philadephia, PennsylvaniaAges 18 years+ - NCT05039216Recruiting
Biobank for inflammatory arthritis and osteoporosis
This study collects and stores health information and samples for people with long-term inflammatory arthritis (like rheumatoid arthritis, spondyloarthritis, or psoriatic arthritis) or with osteoporosis. It helps researchers understand these conditions and may lead to better future treatments.
ToulouseAges 18–99 - NCT05036850Recruiting
Kidney patient research network follow-up study
This trial is for people with a primary (main) kidney disease who can regularly see a kidney doctor. It sets up and includes patients for possible interventional (active) research studies, which may help improve kidney care for future patients.
Beijing, Beijing MunicipalityAges 2 years+ - NCT05041491RecruitingEarly Phase 1
Breaking up sitting time to improve blood sugar
This study tests whether changing how often you sit (adding movement breaks) can improve blood sugar control in people at risk for type 2 diabetes. It compares two activity patterns and uses monitoring and brief hospital-style visits with controlled food.
Aurora, ColoradoAges 18–64 - NCT05042219Recruiting
How lung disease treatment may affect heart function
This study looks at how common long-term lung conditions and their treatments may change heart function. It uses heart imaging (an MRI) to see what’s happening, which could help doctors better monitor heart risks in people with lung disease.
AachenAges 18–99 - NCT05042830Recruiting
Tests how birch allergy in the nose affects allergy signals in blood
This study looks at people with a birch pollen allergy to see how exposure in the nose can change allergy-related blood signals. The results may help explain why symptoms can “boost” throughout the body after nasal allergen contact.
Vienna, State of ViennaAges 18–60 - NCT05045612RecruitingPhase 4
Antibiotics for certain viral lung infections in hospitalized adults
This trial studies whether giving antibiotics affects recovery in adults hospitalized with moderately severe infections caused by specific viruses (influenza, parainfluenza, RSV, or hMPV). It may help show when antibiotics are helpful or unnecessary for viral airway illness.
BergenAges 18 years+ - NCT05046002Recruiting
COVID vaccine heart inflammation symptom registry
This study is a “registry,” meaning it collects medical information about people who develop possible heart inflammation after a COVID-19 vaccine. It may help doctors understand how often this happens and which findings are linked to it.
Ottawa, OntarioAges 5 years+ - NCT05046444Recruiting
Testing tricky blood cancer diagnoses with advanced DNA sequencing
This study uses advanced DNA sequencing to figure out unclear or unusual blood (hematologic) conditions when standard tests are not enough. It may help your care team reach a more accurate diagnosis by better understanding what’s driving your illness.
MunichAges 18–99 - NCT05046483Recruiting
Blood sugar study after a new heart attack
This study measures how your body handles sugar and related hormones in people after a new STEMI heart attack, and compares them with people who do not have diabetes or have prediabetes. The goal is to better understand metabolic changes after the event, which could help future care.
Düsseldorf, North Rhine-WestphaliaAges 18–80 - NCT05048862Recruiting
Brain scan and tests for neuromuscular conditions
