Registry for Exablate treatment in Parkinson’s with medication problems
This trial is a real-world registry that follows people with Parkinson’s who are planning to get an Exablate 4000 procedure (a focused ultrasound treatment) for one-sided symptoms that are difficult to control with medication. It mainly checks outcomes and safety over time, helping doctors understand how well this treatment works in everyday care.
Baltimore, MarylandAges 30–99 - NCT05544266Recruiting
Study rare diabetes patterns to better guide diagnosis
This study looks at people who may have a “non-typical” form of diabetes, including rare genetic causes or unusual symptoms. It may help your care team understand what type of diabetes you have and whether specific genetic testing could explain it.
Aurora, ColoradoAges Any age - NCT05552287RecruitingPhase 4
Infliximab drug levels in children with Crohn’s disease
This study measures how infliximab (a medicine that calms immune inflammation) moves through the body in children with Crohn’s disease. It mainly helps doctors understand dosing and drug levels, especially when treatment is newly starting.
RotterdamAges 1–15 - NCT05553223Recruiting
Very small activity doses for COPD symptoms
This study tests whether “micro-doses” of physical activity (short, small amounts) can help people with COPD. It aims to see if these small activity bursts are safe and beneficial for people who have stable COPD.
Kelowna, British ColumbiaAges Any age - NCT05553873Recruiting
Study links inflammation levels to outcomes in MPN patients
This study looks at inflammation-related lab markers in people with “Ph-negative” myeloproliferative neoplasms (like PV, ET, or PMF) to see how they relate to outcomes and response to treatment. It’s observational, meaning it gathers information from medical records without testing a new treatment.
BariAges 18–99 - NCT05557864Recruiting
Brain scan study for Parkinson’s patients with deep brain stimulators
This study looks at how the location of a deep brain stimulator in Parkinson’s disease affects movement problems. It mainly uses advanced 7T brain imaging to compare brain activity and motor symptoms.
Minneapolis, MinnesotaAges 21–89 - NCT05564273Recruiting
Viome nutrition program for people with metabolic health issues
This trial tests whether a personalized Viome nutrition program can improve metabolic health (such as higher fasting insulin or glucose). You would use their app and follow the program, while researchers monitor health outcomes over time.
Bothell, WashingtonAges 25–75 - NCT05565833RecruitingPhase 2
Online sleep program for insomnia and thinking problems
This Phase 2 study tests an internet-based sleep program to help older adults with insomnia and related thinking difficulties. It may help improve sleep and reduce how much tiredness and sleep disruption affect daily life.
Charlottesville, VirginiaAges 65 years+ - NCT05569122RecruitingPhase 1
Studying an MRI contrast method in mitochondrial muscle disease
This Phase 1 study tests a special MRI approach (using a contrast agent) to better measure changes in muscles in people with mitochondrial diseases. It also includes some healthy volunteers and other critically ill patients to compare results and check safety.
Philadelphia, PennsylvaniaAges 10–60 - NCT05573490Recruiting
Lifestyle program study for early-onset Alzheimer’s
This study tests a structured lifestyle intervention to help people with early-onset Alzheimer’s disease. It is designed for adults with confirmed Alzheimer’s-related brain changes, and may help with symptoms or day-to-day functioning.
Indianapolis, IndianaAges 40–75 - NCT05573802RecruitingPhase 1/Phase 2
Belantamab and other medicines for new multiple myeloma
This early-phase study tests how safe and effective belantamab mafodotin is when combined with lenalidomide and dexamethasone, plus a medicine called nirogacestat, in people with newly diagnosed multiple myeloma who cannot have stem cell transplant. It may help shrink the cancer and improve outcomes, while doctors track side effects.
AthensAges 18 years+ - NCT05573997Recruiting
Testing new ultrasound measures of heart muscle function in heart failure
This study looks at whether a special kind of heart ultrasound can better measure how well the heart muscle works in people admitted with heart failure. It may help doctors understand heart function using clearer ultrasound “biomarkers” soon after hospital admission.
Thessaloniki, Central MacedoniaAges 18 years+ - NCT05576038Recruiting
Tryptophan to help celiac symptoms improve
This trial tests whether tryptophan (a natural amino acid) can improve symptoms in people with celiac disease who still have symptoms despite following a gluten-free diet. It may help by supporting an internal body signal pathway researchers believe is impaired in some people with celiac disease.
Hamilton, OntarioAges 18–75 - NCT05576818RecruitingPhase 3
Synbiotic add-on for people with Parkinson’s disease

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,802 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.
