Recruiting studies
- NCT04417023Enrolling by invitation
Study for people with neuromuscular diseases
This study is for people (or their close family members) who have a neuromuscular disease, such as motor neuron disease, neuropathies, nerve-to-muscle signaling problems, or muscle diseases. It aims to better understand these conditions and how to move from lab findings to care for patients.

Testing an implantable device to study drug response in prostate cancer
This early-phase study uses a tiny implant placed during prostate cancer surgery planning to help researchers measure how tumors respond to treatment while still in the body. The results may help improve future treatment choices for men with intermediate- or high-risk prostate cancer.

Online group counseling for long-term ringing in the ears
This trial tests an internet-based group counseling program for people who have had ongoing (chronic) tinnitus—ringing or other sounds in the ears. It may help you learn coping strategies and reduce how much the condition affects your daily life.
AntwerpAges 18 years+ - NCT04323566Enrolling by invitationPhase 2
Rituximab for OCD or psychosis linked to immune inflammation
This trial tests rituximab (an immune system medicine) to see if it can reduce OCD symptoms and/or psychosis when there are signs the immune system may be involved. You may be considered if other standard psychiatric treatments have not helped enough and your illness seems relatively recent with possible inflammation clues.
UppsalaAges 18–55 - NCT04308707Enrolling by invitation
Training surgeons to deliver difficult news better
This study tests a structured “how to break bad news” training tool for doctors and surgical residents. It may help improve how carefully and clearly clinicians communicate in serious situations.
BarcelonaAges 18 years+ - NCT04294134Enrolling by invitation
Support program for mothers in residential substance treatment
This trial tests a support program for mothers (pregnant or with young children) who are in residential substance use treatment. It aims to improve well-being, family stability, and child safety—especially when children are at risk or in out-of-home placement.
Philadelphia, PennsylvaniaAges Any age - NCT04286464Enrolling by invitation
Study how pregnancy affects airway inflammation in babies
This study looks at how different pregnancy and birth factors may contribute to airway inflammation in infants who wheeze or have lung conditions. It may help researchers understand why some babies get ongoing breathing problems and how early influences could be linked.
BernAges Any age - NCT04275167Enrolling by invitation
Swallowable camera to look at the small intestine in kids
This study uses a capsule camera (a tiny camera you swallow) to help doctors see the small intestine in children with poor growth, or in some adults who are already scheduled for a scope. It may help researchers better understand what’s causing malnourishment when the reason is unclear.
KarachiAges 6 months–70 years - NCT04269447Enrolling by invitation
Collecting samples from people with abdominal aortic aneurysm
This study sets up a long-term biobank by collecting health information and tissue/blood samples from people with an abdominal aortic aneurysm. It may help doctors better understand what causes aneurysms and how to detect or treat them in the future.
Solna, Stockholm CountyAges 50–80 - NCT04150458Enrolling by invitationPhase 3
PET/CT scan test for tumors using a special tracer
This Phase 3 study tests whether a PET/CT scan using a tracer called 18F-fluorocholine can better identify tumors. It may help doctors more accurately find and characterize tumors to guide treatment.
Montreal, QuebecAges 18–110 - NCT04098640Enrolling by invitation
Testing tumor DNA in younger people with metastatic breast cancer
This study looks at your tumor’s molecular (DNA/biologic) features to better understand metastatic breast cancer in people under 50. You may help researchers by providing tissue samples (biopsies) for lab testing.
Seoul, SeoulAges 19–50 - NCT04042532Enrolling by invitation
Theta-burst brain stimulation for younger-onset Alzheimer’s
This trial tests whether a form of brain stimulation (theta-burst stimulation) can improve thinking and memory in people with younger-onset Alzheimer’s. It also compares results with people without dementia who meet similar age and health requirements.
Taoyuan, GuishanAges 50–75 - NCT03995342Enrolling by invitation
Study gut bacteria and frailty in older adults
This study looks at whether gut bacteria (intestinal flora) are linked to frailty in people age 65 and older. It will also test an intervention to see if changing gut bacteria can help reduce frailty.
Xi'an, ShaanxiAges 65 years+ - NCT03984591Enrolling by invitationPhase 4
Compare spironolactone vs eplerenone for heart failure patients
This study uses Denmark’s heart failure registry to compare two common tablet medicines—spironolactone and eplerenone—for people with symptomatic systolic heart failure. It aims to see which one leads to better health outcomes over time.
CopenhagenAges Any age - NCT03976622Enrolling by invitation
Inflammation study in vitiligo and other skin conditions
This study looks at inflammation in people with vitiligo, psoriasis, atopic dermatitis, or alopecia areata. It aims to understand how these conditions compare, which may lead to better treatments.
Bordeaux, BordeauxAges 18–75 - NCT03815279Enrolling by invitationPhase 2
Trial for active or high-risk smoldering myeloma treatments
This Phase 2 study tests a treatment approach for adults with active multiple myeloma (MM) or a high/intermediate-risk “smoldering” MM that hasn’t been treated yet. It may help by trying to control the disease earlier or more effectively, depending on what the trial drug(s) do.
ReykjavikAges 18 years+ - NCT03800160Enrolling by invitation
Metabolic and bariatric surgery registry in Greater China
This is a registry that collects information from people who are having weight- and metabolism-related surgery. Your data may help doctors and researchers understand outcomes and improve care in the region.
Beijing, Beijing MunicipalityAges Any age - NCT03793335Enrolling by invitation
Personalized prevention plan for stomach and colon cancer in the community
This trial tests personalized prevention strategies to help lower the risk of stomach (gastric) and colon (colorectal) cancer in community members. It may help by tailoring screening and prevention steps to your individual health and risk factors.
TaipeiAges 50–75 - NCT03755245Enrolling by invitation
Imaging study using a tracer to measure inflammation in joints and lungs
This trial tests how a radioactive imaging medicine (a tracer called 68Ga-DOTA-Siglec-9) spreads in the body and how well it shows inflammation. It includes both healthy volunteers and people with active rheumatoid arthritis, vasculitis, or pulmonary sarcoidosis to see if the scan matches disease activity.
TurkuAges 18–70 - NCT03685188Enrolling by invitationPhase 4
Oxycodone and sufentanil pain medicine for hip surgery
This trial tests whether using oxycodone and sufentanil helps control pain during one-sided hip surgery. It’s meant to see how well these pain medicines work and whether they are safe for patients in this setting.
Chengdu, SichuanAges 18 years+ - NCT03648359Enrolling by invitation
MRI scans to monitor low-risk prostate cancer in active surveillance
This trial uses special MRI scans to help track low-risk prostate cancer while you stay on active surveillance (meaning no immediate treatment). It may help your care team better understand changes in the cancer over time.
HerlevAges 18–75 - NCT03541785Enrolling by invitation
Using NGAL to guide fluids and start kidney-filtering in children
This study tests whether measuring a urine protein called NGAL can help doctors choose the right fluid amount and decide when to start a kidney-filtering treatment called CRRT in critically ill children with kidney injury. If it works, it may help treat kidney problems sooner and more safely.

- How do I know if I qualify for a hospitalization 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 hospitalization 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.
