Hospital study following people with plasma cell disorders
This is a hospital-based study that follows people with plasma cell disorders to better understand these conditions. It mainly gathers information from patients who are confirmed to have one of several related diseases.
BeijingAges Any age - NCT05294107Recruiting
Intestinal organoid study in digestive biopsies
This study collects small tissue samples (biopsies) during a routine endoscopy to create organoids—miniature versions of your intestine grown in a lab. The goal is to better understand digestive diseases and test potential treatments. You may be eligible if you're already scheduled for an endoscopy.
RennesAges 18–75 - NCT05309707Recruiting
Branched stents for certain aortic arch problems
This study looks at using special branched stent-grafts to treat problems in the aortic arch (such as aneurysm or certain tears). It focuses on how well this approach works and how patients do over follow-up visits.
MadridAges 18–90 - NCT05315895Recruiting
Study of people with “dampness” signs in Chinese medicine
This is an observational study that looks at a Chinese-medicine pattern called “dampness” by collecting health and biological information from volunteers. It may help researchers better understand what this pattern looks like and how it relates to people’s health.
Guangzhou, GuangdongAges 35–79 - NCT05333471RecruitingPhase 1/Phase 2
Fecal transplant for chronic bowel inflammation in CGD
This study tests whether transplanting stool microbiome (fecal microbiota transplant) can improve chronic colitis in people with chronic granulomatous disease (CGD). It aims to reduce bowel inflammation and symptoms by changing gut bacteria.
Bethesda, MarylandAges 10–60 - NCT05364294Recruiting
Molecular testing for rare inflammatory (autoinflammatory) diseases
This study uses lab testing to better identify the cause of certain rare inflammatory conditions that happen without infection. Finding the cause may help doctors choose more targeted care for you or your child.
ParisAges 1 week–120 years - NCT05365009Recruiting
Autoimmune lung scarring registry for adults with recent diagnosis
This registry collects health and breathing test information from adults with autoimmune-related lung scarring (interstitial lung disease) diagnosed recently. It helps researchers better understand who has this condition and how it changes over time.
Buenos AiresAges 18 years+ - NCT05370014Recruiting
Study for COVID survivors and their unpaid carepartners in South Carolina
This study looks at how to improve health and support for African American adults who had COVID-19 severe enough to need urgent care or hospitalization, along with the unpaid carepartner who helps them at home. It may be helpful if you and your carepartner live in a medically underserved or rural area and share daily support needs.
Columbia, South CarolinaAges 18 years+ - NCT05378139Recruiting
At-home and hospital wireless monitoring for worsening health
This trial tests a system that continuously checks vital signs (like heart rate and breathing) using wireless sensors and sends automatic alerts if you seem to be getting worse. It may help clinicians spot problems sooner whether you’re being monitored at home or around a major surgery hospital stay.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
