Recruiting studies
- NCT04775355Recruiting
Track urine and gut changes during prostate cancer treatment
This study looks at how your urine and gut (intestine) microbes change while you undergo prostate cancer treatments, including hormone therapy (androgen deprivation) and/or radiation. The goal is to better understand these biological changes, which may help improve future treatment planning.

Abemaciclib plus hormone pills for metastatic breast cancer in older adults
This Phase 2 study tests whether abemaciclib combined with standard hormone (endocrine) therapy can better control metastatic breast cancer in people age 70 and older. It may help if your cancer has already grown despite prior hormone therapy and/or other cancer medicines.
Duarte, CaliforniaAges 70 years+ - NCT07615764Recruiting

Seattle, WashingtonAges 50–80 - NCT07650656RecruitingPhase 2
Fluorescence-Guided Surgery to Improve Sarcoma Tumor Removal
This trial tests a special dye and imaging technique to help surgeons see and remove sarcoma tumors more completely. The goal is to reduce the chance that cancer cells are accidentally left behind during surgery.
Duarte, CaliforniaAges Any age - NCT00736749Recruiting
Long-term health check for childhood cancer survivors
This trial tracks the long-term health of people who took part in previous Children's Oncology Group studies. It helps doctors understand the lasting effects of cancer treatment and improve care for survivors.
Birmingham, AlabamaAges Any age - NCT07516366RecruitingPhase 2
Immunotherapy before surgery for clear cell kidney cancer
This trial tests whether giving two immunotherapy drugs before surgery can safely shrink kidney cancer tumors and help your body fight the cancer. You would receive the drugs before your scheduled surgery, and then your cancer would be removed as planned.
Irvine, CaliforniaAges 18 years+ - NCT07660068Enrolling by invitation
HoLEP and Sexual Recovery
This study looks at how HoLEP surgery affects sexual function, particularly ejaculation. It's for men who are getting HoLEP to relieve bothersome urinary symptoms.
Chicago, IllinoisAges 18–100 - NCT07557056RecruitingPhase 2
Oral combination treatment for untreated chronic lymphocytic leukemia
This clinical trial tests two oral medications, nemtabrutinib and venetoclax, given together to people with untreated CLL or SLL. The goal is to see if this combination effectively kills cancer cells and helps you stay in remission with manageable side effects.
Columbus, OhioAges 18 years+ - NCT01194648Recruiting
HIFU treatment for early prostate cancer
This trial studies a focused ultrasound treatment called HIFU for prostate cancer that appears limited to the early stages. It aims to treat cancer within the prostate while avoiding treatment spread to lymph nodes or distant organs.
London, EnglandAges Up to 90 years - NCT03659019Recruiting
Database study for implanted phrenic nerve stimulators
This study collects information about people with long-term breathing problems who may receive an implanted device that helps control breathing. It helps doctors better understand who benefits and how these treatments are used in real life.
Paris, Île-de-France RegionAges 5 years+ - NCT04800289Recruiting
Joint skin and joint clinic satisfaction and impact study
This study looks at how patients feel about a combined skin-and-joint doctor visit and whether that visit helps. It mainly involves people who attend the hospital’s joint rheumatologist/dermatologist consultation.
Le MansAges 18 years+ - NCT03335644Recruiting
Internet-based health study for people 15 and older
This study gathers health information through an online program. It may help researchers understand how diet and lifestyle affect health over time.
Bobigny, Seine Saint DenisAges 15 years+ - NCT05305092Recruiting
Study of memory and thinking in early breast cancer
This study checks how breast cancer affects memory and thinking before other treatments start. It may help doctors better understand cognitive changes and who is most at risk.
Xi'an, ShaanxiAges Any age - NCT02931513Recruiting
Blood marker test in newly diagnosed PBC patients
This study looks at how a specific blood marker (sCD163) changes in people newly diagnosed with primary biliary cholangitis (PBC). It’s mainly meant to see whether this marker could help predict treatment response, especially before starting UDCA.
Aarhus C, Central JutlandAges 18 years+ - NCT05746793Recruiting
IVF pregnancy study to prevent pre-eclampsia in high-risk women
This trial studies ways to lower the risk of pre-eclampsia (dangerous high blood pressure in pregnancy) in women who are having a first pregnancy through IVF/ICSI or who have PCOS. It’s aimed at people considered higher risk for pre-eclampsia.
BrusselsAges 18–48 - NCT05054296RecruitingPhase 2
Exercise and Fitbit monitoring to lower heart risk in prostate cancer
This Phase 2 study tests whether a structured exercise and lifestyle program, tracked with a Fitbit, can reduce cardiovascular (heart) risk in men with prostate cancer on hormone therapy. It also checks whether this is safe and feasible while monitoring symptoms and fitness changes.
Houston, TexasAges 18 years+ - NCT03052283Recruiting
Abdominal symptom score test for people with cystic fibrosis
This trial helps create and check a patient-friendly questionnaire that measures abdominal (belly) involvement in cystic fibrosis. It may help your care team better track symptoms over time.
Brandenburg an der HavelAges Any age - NCT04343443Recruiting
Test whether a lung ultrasound helps discharge planning after heart failure
This study looks at people hospitalized for worsening heart failure with weaker pumping (reduced ejection fraction). It tests whether a lung ultrasound evaluation near discharge can improve how doctors decide it is safe to send you home.
Vandœuvre-lès-NancyAges 18 years+ - NCT05089162Recruiting
Testing a heart ultrasound approach in chronic heart failure
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
Vandœuvre-lès-NancyAges 18 years+ - NCT04332692Recruiting
Check if a lung ultrasound helps evaluate discharge after heart failure
This study looks at whether doing lung ultrasounds can better assess people right before they leave the hospital after an acute heart failure flare. It may help doctors decide when someone is ready for discharge and tailor care to reduce risk after leaving.
Vandœuvre-lès-NancyAges 18 years+ - NCT04343430Recruiting
Hospital study for fluid buildup in heart failure with preserved heart function
This study looks at how well doctors can assess fluid buildup before you leave the hospital if you have a type of heart failure called “preserved ejection fraction.” It may help improve decisions about when and how safely people are discharged.
Vandœuvre-lès-NancyAges 18 years+ - NCT05097898Recruiting
Check fluid buildup in heart failure with normal pumping
This study evaluates how well doctors can assess “fluid congestion” in people with chronic heart failure where the heart’s squeezing is still preserved. It may help improve how patients are monitored during hospital visits.

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