Rochester, MinnesotaAges 18 years+ - NCT04239573Recruiting
Compare pancreatic cyst checkup programs and test markers
This study compares different ways to monitor pancreatic cysts and also measures blood or other test markers to see which approach is more helpful. It may help patients by finding the safest, most effective way to track certain cysts that could otherwise be hard to manage.
Birmingham, AlabamaAges 50–75 - NCT04179981Recruiting
CPAP treatment effects in older COPD and sleep apnea patients
This study looks at whether using positive airway pressure (often called CPAP) improves health outcomes in older adults who have both COPD and obstructive sleep apnea. It may help find ways to reduce symptoms and complications from “overlap” breathing problems.
Detroit, MichiganAges 60 years+ - NCT03918421Recruiting
IgM-MAG neuropathy study using immunoglobulin M treatment
This study looks at a treatment made from immune proteins (immunoglobulin M) to treat neuropathy caused by anti-MAG antibodies. It may help improve nerve symptoms in people with this specific type of nerve condition.
BronAges 18 years+ - NCT04242095Recruiting
Immunotherapy side effects research study
This study collects blood, stool, and tissue samples from people who have had side effects from immunotherapy (a type of cancer treatment that helps your immune system fight cancer). It aims to learn more about these side effects, so doctors can better manage them in the future.
Anchorage, AlaskaAges Any age - NCT04243356Enrolling by invitation
ICU nurse involvement in a post-ICU follow-up clinic
This study looks at whether having ICU nurses actively involved in a follow-up clinic after ICU discharge improves patients’ recovery and follow-up care. It focuses on patients who were cared for in the ICU and the registered nurses who cared for them.
Ann Arbor, MichiganAges 18 years+ - NCT04226313Recruiting
Home self-swab tests for people not doing cervical screening
This study looks at whether a home self-sampling swab can help people who haven’t joined cervical cancer screening in the past few years. If you qualify, you’ll be asked to collect a swab yourself so it can be tested, aiming to make screening easier to access.
OlomoucAges 30–65 - NCT04199000Recruiting
Study for congenital glycosylation disorders and NGLY1 deficiency
This trial is for people who have a confirmed genetic condition related to how the body builds certain sugar-like structures (CDG) or NGLY1 deficiency. It aims to better understand these conditions through clinical and basic science research, which may help improve future care.
San Diego, CaliforniaAges Any age - NCT04240119Enrolling by invitation
Study blood vessel growth markers in certain brain artery narrowing
This study looks at “angiogenic markers,” which are blood measures that may reflect how blood vessels grow, in people with significant narrowing of a brain artery. It aims to better understand these changes and how they relate to cerebrovascular disease.
Ages 18 years+ - NCT04194996Recruiting
Study of surgery for crooked or bent neck alignment
This study looks at how well planned surgery corrects neck (cervical) deformities and how the results change over time. It mainly involves standard pre- and follow-up imaging and study questionnaires to compare clinical and X-ray outcomes.
La Jolla, CaliforniaAges 18 years+ - NCT04232566Recruiting
Study links in obesity surgery and liver scarring
This study looks at how the immune system relates to liver scarring in people with obesity who are getting gastric bypass surgery. If you qualify, you may help doctors better understand liver disease and who is at higher risk.
Scottsdale, ArizonaAges 30–70 - NCT04171830Enrolling by invitation
Screening for palliative needs in the last year of life
This trial uses a special tool to check if patients in the hospital have unmet needs for comfort and quality-of-life care. It is designed for patients who may be in their final year of life, helping doctors and nurses offer extra support sooner.

Common questions
- Are there clinical trials for clinical?
- Yes. Clin2 currently lists 5,427 recruiting clinical 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 clinical 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 clinical 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.
