SeoulAges 19 years+ - NCT04186286RecruitingPhase 2
Testing propranolol vs ivabradine for POTS symptoms
This study compares two heart-rate medicines—propranolol and ivabradine—to see which better improves symptoms in people with POTS. It uses a “crossover” design, meaning you may try one medicine and then switch to the other.
Calgary, AlbertaAges 18–60 - NCT04194619Recruiting
Study of pregnancy safety in women with rare blood-vessel diseases
This study looks at pregnancy and the early period after birth in women with rare diseases that affect blood vessels. It may help doctors understand risks and improve care for future pregnancies.
AngersAges 18–45 - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04196595Recruiting
Apple study for women’s health using an iPhone app
This study looks at women’s health by collecting information through an Apple Research app on your iPhone. You may help improve how health data is gathered, while also checking in with the study team by agreeing to participate.
Boston, MassachusettsAges 18 years+ - NCT04198740Recruiting
Test tear fluid and eye chemistry patterns in eye surface diseases
This study looks at tiny chemical patterns in tear fluid to better understand different causes of eye surface problems. Your participation may help researchers compare healthy eyes with conditions like dry eye, infections, or allergies.
Montreal, QuebecAges 18 years+ - NCT04208126Recruiting
Early versus late ECMO start for severe lung failure
This trial compares starting ECMO early versus later in adults with severe lung failure (ARDS). It tests whether starting the life-support machine sooner can improve outcomes by the time doctors need it.
TübingenAges 18 years+ - NCT04218344Recruiting
Heart attack and chest pain study at Harefield hospital
This study follows people who come to Harefield for urgent heart-related chest pain and planned heart-vessel imaging (coronary angiography). It aims to better understand these conditions and what doctors see during the procedure, which may improve care for future patients.
Harefield, MiddlesexAges Any age - NCT04221737Recruiting
Early breathing support for ARDS using a pressure release ventilator
This study looks at starting a specific type of breathing machine setting early in people with ARDS (a serious lung problem) to see if it improves outcomes. You might be able to take part if you are within 48 hours of needing a breathing tube and meet the lung oxygen criteria.
Guadalajara, JaliscoAges 18–80 - NCT04251078Recruiting
Blood tests to track mutations in lower-risk MDS
This study uses repeated blood samples to watch how genetic changes in your blood evolve in lower-risk myelodysplastic syndrome (MDS). It may help doctors understand what mutation changes mean over time for people not on strong cancer-fighting treatments.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,196 recruiting down syndrome studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a down syndrome trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a down syndrome trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
