A closer look at inherited mitochondrial brain disease
This study collects medical information from people with mitochondrial leukoencephalopathy (a rare genetic disease that damages the brain's white matter) to learn how the disease progresses and how different gene changes affect symptoms. By joining, you can help researchers better understand the condition and improve future care for others.
MilanAges Any age - NCT06396871Recruiting
Blood cell study in metabolic diseases
This study looks at blood cells and factors in people with metabolic diseases like fatty liver, prediabetes, or type 2 diabetes. It aims to better understand these conditions by comparing them with healthy volunteers.
Dresden, SaxonyAges 18 years+ - NCT06397677Recruiting
Study of Progressive RA Interstitial Lung Disease
This study is looking at people with rheumatoid arthritis (RA) who also have interstitial lung disease (ILD), a condition that causes scarring in the lungs. It aims to understand how the disease changes over time by using imaging and blood tests, without providing any new treatments right now.
San Francisco, CaliforniaAges 18–90 - NCT04359394Recruiting
Rare severe pustular psoriasis family DNA study network
This study builds a large international registry of people with rare, severe pustular psoriasis to help doctors understand the genetics of the condition. You may be asked for information and, if you have eligible family members, DNA testing to learn how the disease runs in families.
MünchenAges 6 months+ - NCT06405997Recruiting
Study of LAM: genes and symptoms
This study looks at the genes and physical traits of people with lymphangioleiomyomatosis (LAM), a rare lung disease that causes cysts. It aims to help better understand and treat LAM.

Testing detailed heart scans in people with heart failure symptoms
This study looks at whether doing very detailed heart testing helps understand and guide care for people with heart failure with preserved pumping strength. You may be eligible if you’re an adult with specific symptom levels, recent heart-failure-related visits, and matching scan and blood test results.
GroningenAges 18 years+ - NCT07851493Recruiting
Exercise assessment before chemotherapy for multiple myeloma
This study looks at how exercise affects the body before you start chemotherapy for multiple myeloma. It aims to understand your fitness level to help tailor treatment support.

BerlinAges 18–75 - NCT05817734Recruiting
Research study to collect health information from adults
This is a research study that collects information about your health and traits to better understand human health and variation. It is mainly for adults who can consent and do not have several specific medical situations listed below.
RehovotAges 18 years+ - NCT06513247Recruiting
Screening for type 1 diabetes in high-risk relatives
This study screens high-risk children for early signs of type 1 diabetes by testing relatives who already have the condition. It aims to catch diabetes early so treatment can start sooner.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 312 recruiting phenotype 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 phenotype 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 phenotype 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.
