Baricitinib for Job syndrome with lupus or eczema
This study tests if baricitinib, a pill that changes how your immune system works, is safe and tolerable for people with Job syndrome who also have lupus-like disease or severe eczema. It might offer a new treatment option for these skin and immune problems.
Bethesda, MarylandAges 12–120 - NCT07838675Recruiting

BelfastAges 18 years+ - NCT07874412Recruiting
Distractions in the operating room and their effect on care
This study looks at what happens in the operating room during colorectal surgery, such as distractions and how the team works together, to see if these affect patient safety.
AthensAges 18 years+ - NCT05913908Recruiting
Valve procedure study for severe tricuspid leakage
This trial tests how well a new catheter-based valve system works for people with severe (or worse) tricuspid valve leaking who still have symptoms despite medicines. It aims to improve outcomes by treating the leaking valve without open-heart surgery, if your heart structure and overall health fit the study.
Phoenix, ArizonaAges 18 years+ - NCT06463587RecruitingPhase 3
Oral cladribine for generalized myasthenia gravis
This study tests a new oral medication (cladribine) to see if it can reduce muscle weakness and daily symptoms in people with generalized myasthenia gravis. It compares the drug to a placebo (a pill with no active medicine) to check safety and effectiveness.
Phoenix, ArizonaAges 18 years+ - NCT06664814RecruitingPhase 2
Study of ManNAc for kidney diseases with proteinuria
This study tests a new drug called ManNAc for people with certain kidney diseases (FSGS, MCD, or MN) that cause protein in the urine. The goal is to see if this drug can help reduce protein loss and improve kidney health.
Bethesda, MarylandAges 18–115 - NCT05678491Enrolling by invitation
Endoscopic treatment for reflux after gastric sleeve surgery
This trial studies an endoscopic procedure to treat gastroesophageal reflux disease (GERD) in people who had gastric sleeve surgery. It may help if reflux symptoms are not controlled on once-daily acid medicine (PPI) or if you cannot tolerate it and want an alternative.
TrondheimAges 18–70 - NCT06948110Recruiting
Searching for genes linked to autoimmune diseases
This study looks for genes that may be linked to autoimmune diseases by comparing the DNA of people with these conditions to healthy family members or volunteers. If you have an autoimmune disease or are a healthy person interested in helping research, this study may help scientists understand why these diseases run in families.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,565 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.
