Exercise study for immune changes in indolent blood cancers
This study looks at how an exercise program may change parts of the immune system in people with slow-growing (indolent) non-Hodgkin lymphoma or chronic lymphocytic leukemia (CLL/SLL). It may help researchers understand which immune changes could be important for your condition.
Scottsdale, ArizonaAges 18–80 - NCT05894616Recruiting
Home monitoring study for lasting breathing symptoms after COVID
This study looks at people with lingering post-COVID symptoms, especially breathing and lung-related findings, using home monitoring and medical tests. It may help researchers understand what’s driving ongoing symptoms and identify patterns that could guide better care.
Stockholm, SverigeAges 18–50 - NCT05896579Recruiting
Study heart function during rest and exercise in COPD
This study measures how well the right side of your heart works when you are resting and when you exercise, in people with chronic obstructive pulmonary disease (COPD). It may help researchers better understand COPD-related heart strain and guide future care.
Aurora, ColoradoAges 40 years+ - NCT05916755Recruiting
Testing tumor clues that predict response to immunotherapy
This study looks for “biomarkers,” or tumor clues, that may help predict who benefits from checkpoint inhibitor immunotherapy in triple-negative breast cancer. It may help doctors choose the right treatment approach in the future, especially when chemotherapy is planned.
BarcelonaAges 18 years+ - NCT05925790Recruiting
Testing immune markers in recurring pericarditis
This study looks at immune blood markers to understand different types of recurring inflammation around the heart (pericarditis). The goal is to see whether certain marker patterns (like IL-1RA antibodies and suPAR) are linked to inflammation and what might be driving it.
HomburgAges 18–90 - NCT05978141Recruiting
T-cell lymphoma registry study
This study creates a registry for people with certain T-cell or NK-cell lymphomas. It collects health information and tumor samples to learn more about these diseases and improve future treatments.
Duarte, CaliforniaAges Any age - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT06062303Recruiting
Capillary refill time to guide septic shock treatment
This trial tests a new way of giving fluids and medicines to people with septic shock. It focuses on a simple sign called capillary refill time (how fast color returns when you press a fingernail) to guide treatment, aiming to improve recovery.
ReimsAges 18 years+ - NCT06085833Recruiting
Using ARTIDIS to measure early breast lesions
This trial tests a new device called ARTIDIS that measures the stiffness of breast tissue to help identify early breast lesions. It may provide a noninvasive way to assess breast health.
Dallas, TexasAges 18 years+ - NCT06123962Recruiting
Identifying lung injury subtypes to guide treatment
This study looks at different patterns in patients with a severe lung condition called ARDS, to better understand why some respond to treatments differently. You may help doctors learn how to personalize care.
BeijingAges 18 years+ - NCT06163794Recruiting
Nutritional support for healthy aging in older adults
This study tests a personalized nutrition program for older adults to see if it can help maintain muscle strength and overall health. It looks at your grip strength, body mass index (BMI), where you live, and your cognitive ability.
Clermont-Ferrand, FranceAges 60–75 - NCT06196034Recruiting
Genetic study of asthma severity and types
This study looks at how genes are linked to different types and severities of asthma. It aims to understand why asthma affects people differently, which could lead to better treatments.

Common questions
- Are there clinical trials for phenotype?
- Yes. Clin2 currently lists 318 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.
