Compare antipsychotic medicines for Parkinson or Lewy body psychosis
This study compares two medicines—quetiapine and pimavanserin—in people with psychosis caused by Parkinson’s disease or Lewy body dementia, looking at how they work over time. You might join if you are starting an antipsychotic for the first time and your clinician can safely manage either option.

Testing a TNF-blocking drug to reduce death in HIV and TB meningitis
This Phase 2 trial studies whether a TNF-blocking medicine can lower the risk of death in people with HIV who also have TB meningitis. You would receive standard TB meningitis treatment plus the study drug, if you meet the criteria.
Rio de JaneiroAges 18 years+ - NCT05591027RecruitingPhase 1
Testing Centella asiatica for memory problems in older adults
This Phase 1 study tests whether Centella asiatica (a plant-based supplement) is safe and reaches its intended target in people with mild cognitive impairment or early Alzheimer’s disease. It also checks how it affects memory-related brain measures like MRI scans, which is why multiple scans are required.
Portland, OregonAges 60–85 - NCT05592366Recruiting
Testing a hospital tool for unpaid dementia caregivers
This study is testing a care-partner support tool for people who provide unpaid care to a hospitalized adult loved one or partner with dementia-related needs. It may help caregivers and hospitals communicate and coordinate better during a hospital stay.

How dental implant shape affects gum and bone disease rates
This study looks at whether the way a dental implant is restored (the “prosthetic emergence profile,” or how it comes up through the gum) affects how often gum and tissue problems happen around implants. It may help clinicians choose restoration styles that lower the risk of peri-implant diseases.
Sant Cugat del Vallès, BarcelonaAges 18–80 - NCT05592678Recruiting
Study brain and memory test changes in Alzheimer’s or mild issues
This study looks at how well people with Alzheimer’s disease (AD) or mild cognitive impairment (MCI) perform on standardized memory/brain tests. It may help researchers understand changes over time, and whether certain types of brain signals or test results track with the condition.
San Antonio, TexasAges 65–100 - NCT05594927RecruitingPhase 3
Test icaritin vs huachansu for advanced liver cancer with poor health
This Phase 3 trial compares two medicines—icaritin soft capsules versus huachansu tablets—as first treatment for unresectable hepatocellular carcinoma (HCC) that has “poor prognosis” blood test markers. It aims to see which option works better and is safer for people who can’t use standard first-line treatments or don’t want them.
Nanchang, JiangxiAges 18 years+ - NCT05595408Recruiting
Tracking tumor DNA to predict relapse after upper kidney cancer surgery
This study checks tumor DNA found in blood and urine to see who is at higher risk of the cancer coming back after surgery. It may help doctors identify “minimal residual disease,” meaning tiny amounts of cancer that can remain after treatment.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05595447RecruitingPhase 2/Phase 3
Testing new treatment for Hodgkin lymphoma that came back
This study tests a treatment plan for adults with Hodgkin lymphoma that has returned or did not respond to ABVD chemotherapy. It may help people with a higher-risk pattern of disease, as long as their organ function and overall health meet study limits.
León, GuanajuatoAges 15–90 - NCT05597124RecruitingPhase 2
Exercise program to improve brain health in older Black adults
This Phase 2 study tests whether a structured exercise program can improve brain health in adults age 60 and older who are less active and have early thinking/memory concerns. It may help maintain or improve thinking abilities over time, with medical supervision throughout the study.
Newark, New JerseyAges 60 years+ - NCT05597709Recruiting
Study diabetes patients to measure MAFLD in Jiangsu
This study checks how common a condition called MAFLD is among people with type 2 diabetes in Jiangsu, China. It may help doctors understand how often this liver-related problem occurs and guide future care for people with type 2 diabetes.
Nanjing, JiangsuAges 18 years+ - NCT05598879Recruiting
New heart-cancer visit registry for adults
This study is a “registry,” meaning it collects health information from adults who are getting a new heart (cardio) evaluation related to cancer. It helps doctors better understand heart risks and care needs for different cancer types and treatments.
Weston, FloridaAges 18 years+ - NCT05598632Recruiting
People with atrial fibrillation registry to study stroke risk
This registry study follows people with atrial fibrillation to learn which risk factors are linked to stroke or blood clots traveling through the body. Your information helps improve how doctors predict risk and choose prevention strategies.
Beijing, Beijing MunicipalityAges 18–120 - NCT05600920RecruitingPhase 1/Phase 2
Long-acting IL-7 drug trial for low CD4 immune cells
This Phase 1/2 study tests a long-acting IL-7 medicine to raise low CD4 immune cells in people with idiopathic CD4 lymphopenia. Because this is a dose-escalation study, the goal is to check safety and see if the treatment affects immune cell levels.
Bethesda, MarylandAges 18–75 - NCT05600946Recruiting
Study of body differences in creatine transporter deficiency
This study looks at physical and body features in people with creatine transporter deficiency caused by a specific gene change (SLC6A8). It may help doctors better understand the condition and how it shows up, which can improve future care.
Bethesda, MarylandAges 2–40 - NCT05603520Recruiting
Study of how the aorta varies in healthy people and patients
This study uses MRI scans to understand how different parts of the aorta look and behave, including in healthy volunteers and people with aortic problems. It may help researchers better describe differences in the aorta that could improve future diagnosis or treatment planning.
DüsseldorfAges 18 years+ - NCT05607888Recruiting
Study of treatment for sinus and skull-base tumors
This study looks at how doctors manage tumors that start in the nose/sinuses and spread to the skull base. It may help improve planning of care for people with this specific type and location of tumor.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
