Study of mezagitamab for IgA nephropathy
This trial tests a new drug called mezagitamab for adults with IgA nephropathy, a kidney condition. The study aims to see if this drug can help reduce protein in the urine and preserve kidney function. You may be eligible if your kidney function is above a certain level and your urine protein is high enough.
Birmingham, AlabamaAges 18 years+ - NCT07763340Recruiting
Photon-counting ct heart scan for people with coronary stents
This study tests a new type of CT scan that takes very detailed pictures of the heart and stents. It may help doctors see whether stents remain open and guide future care.
Beijing, Beijing MunicipalityAges 18–100 - NCT07764354Recruiting
Patient education for sticking with home exercises
This study tests whether extra education helps people with chronic musculoskeletal conditions—like long-term back pain, knee arthritis, or partial rotator cuff tears—stick with their home exercise routines to feel better. If you have one of these conditions and are willing to follow a home exercise plan, this could help you manage pain.
Dammam, Eastern ProvinceAges Any age - NCT07761377Recruiting
Using AI to spot lung scarring on CT scans
This study tests whether an AI tool can correctly find lung scarring (pulmonary fibrosis) on CT scans as well as doctors do. The results could lead to faster, more consistent detection of this condition.
TaichungAges 20 years+ - NCT06072911Recruiting
Men's health after prostate cancer surgery study
This study looks at how men recover control of urine and sexual function after prostate removal surgery. It also tests if a 12-week exercise program can help improve these functions.
Edmonton, AlbertaAges 18 years+ - NCT07335341Recruiting
Liberant thrombectomy system case survey
This survey collects feedback from doctors who used the Liberant system to remove blood clots. The results help understand how well the device works in real-life procedures.
Washington D.C., District of ColumbiaAges 22 years+ - NCT06837246Recruiting
Nutritional supplement study for cognitive health in adults
This study tests whether a nutritional supplement taken as 3 capsules daily for 12 weeks can improve cognitive function. It is designed for generally healthy adults who do not have certain medical conditions or take certain medications.
Addison, IllinoisAges 25–65 - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT07425574Recruiting
Study on how Stargardt eye conditions progress in children and adults
This study observes how Stargardt disease and similar eye conditions change over time in children and adults. It aims to learn more about the disease progression to help develop future treatments.
Phoenix, ArizonaAges 6 years+ - NCT06832774RecruitingPhase 2
Hormone therapy plus local treatment for advanced prostate cancer
This study tests adding a targeted local treatment (like radiation or surgery) to standard hormone therapy for men with advanced prostate cancer that still shows up on a special scan. The goal is to see if this combination helps control the cancer better.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06462742Recruiting
Microwave ablation vs. surgery for intrahepatic cholangiocarcinoma
This trial compares two treatments for a liver cancer called intrahepatic cholangiocarcinoma—surgery to remove the tumor versus microwave ablation, which uses heat to destroy cancer cells. It tests if ablation works as well as surgery for people with small tumors that haven't spread.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05990179Recruiting
Screening newborns for rare diseases using genetics
This trial offers free genetic screening for rare diseases in newborns. It aims to find health conditions early so babies can get the right care sooner.
New York, New YorkAges 1 day–1 month - NCT05608772Recruiting
Revision weight-loss surgery after failed sleeve
This study looks at which revision surgery works best after a prior sleeve stomach operation that didn’t last. It tests switching to one of three procedures to help with weight regain, and it excludes more severe acid reflux cases.
Alexandria, Alexandria GovernorateAges 18–60 - NCT04542720Recruiting
Nerve-Pressure Surgery Alone or With Spine Fusion
This trial compares two surgical options for the level just above a prior lumbar fusion: removing pressure on the nerve versus removing pressure plus adding a fusion. It may help determine which approach better treats ongoing nerve-related symptoms when other non-surgical treatments have not worked.
Boston, MassachusettsAges 18 years+ - NCT02998411Recruiting
Blood sample study of antibiotics in hospitalized patients
This study looks at how antibiotics move through the body in adults who are hospitalized. By measuring antibiotic levels in blood (or other body samples), the team may better understand dosing for safer, more effective treatment.
Paris, ParisAges 18 years+ - NCT02743845Recruiting
Find genetic answers for rare, possibly inherited conditions
This trial looks for gene changes that may explain rare conditions, even when the diagnosis is not fully understood. It may help families who have a rare condition or who are related to someone with one.
Boston, MassachusettsAges Any age - NCT04866251Recruiting
Tests gag reflex differences in healthy people and patient groups
This study measures your gag reflex (how strongly you gag when stimulated) and compares it across different groups. The results may help improve screening for swallowing problems (called dysphagia).
Giessen, HesseAges 18 years+ - NCT02927158Recruiting
Genetic testing study for Amish and Mennonite community members

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,783 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.
