Studying people in Hong Kong who may have sleep apnea
This study looks at people who may have obstructive sleep apnea, a breathing problem during sleep. It aims to better understand the condition in Hong Kong and what to do next for diagnosis or care.
Hong Kong, Please SelectAges 18 years+ - NCT04716140Recruiting
Study of outcomes after bunion surgery for cartilage damage
This study looks at how well bunion (hallux valgus) surgery works, especially when there is cartilage damage in the joint. The goal is to see what factors predict better or worse outcomes after treatment.
GhentAges 30–60 - NCT04741230Recruiting
Test implant for severe corneal thinning to avoid transplant
This study tests a procedure called Xenia corneal lenticule in people with severe keratoconus or severe post-LASIK corneal thinning who want to avoid a corneal transplant. It aims to improve vision while checking safety and how well the new procedure works over time.
Wolverhampton, West MidlandsAges 18–79 - NCT04766515Recruiting
Study of immune checkpoint cancer treatment in real life
This is an observational study that follows adults with solid cancer who are receiving immune checkpoint inhibitor treatments. It aims to learn how these medicines are used and what outcomes may look like in everyday care.
ShanghaiAges 18 years+ - NCT04773366RecruitingPhase 3
Newly diagnosed LCH children may receive cytarabine treatment
This Phase 3 trial tests a treatment plan that includes cytarabine for children newly diagnosed with LCH (a rare condition where abnormal immune-related cells form lesions). It may help control the disease while comparing outcomes with a cytarabine-based protocol.
ShanghaiAges 1 day–18 years - NCT04803916Recruiting
Balloon dilation study for Crohn’s bowel strictures
This study looks at inflammation just before a narrowed section of the bowel in people with Crohn’s disease, using planned endoscopic balloon dilation. It may help doctors better understand what drives narrowing and inflammation so treatment can be timed and chosen more effectively.
JerusalemAges Any age - NCT04806412Recruiting
Gene testing in lung cancer fluid samples
This study looks at fluid from around the lungs (pleural fluid) to find gene changes (oncodrivers) in people with non-small cell lung cancer. The goal is to see if this fluid can replace a tissue biopsy for testing.
Næstved, Region SjællandAges 18 years+ - NCT04838171Recruiting
Study of White Blood Cells in Donors and Patients
This study looks at white blood cells (the body’s immune cells) to learn more about how they behave in health and/or illness. Participation may help researchers understand immune-related changes and support future treatments.
LondonAges Any age - NCT04893954Recruiting
Study of spine changes after weight loss from bariatric surgery
This study looks at how rapid weight loss after bariatric surgery may affect your spine over the following year or more. It may help doctors better predict who gets spine-related problems or improvements after surgery.
ParisAges 18 years+ - NCT07699705Recruiting
Proton Beam Therapy for Localized Prostate Cancer
This study tests a very short course (ultrahypofractionated) of proton beam radiation for localized prostate cancer. It aims to see if it's safe and effective with fewer treatment visits.
Goyang-si, Gyeonggi-doAges 19 years+ - NCT05053945Recruiting
Track stomach changes after H. pylori infection
This study follows adults with past or current H. pylori infection to better understand stomach lining changes such as atrophic gastritis and intestinal metaplasia, and to monitor for possible progression. It may help by improving how doctors track risk over time and use stored tissue samples to learn more.

Testing high-flow oxygen during EBUS with monitored sedation
This study looks at whether using high-flow oxygen through the nose during a specific lung procedure (EBUS bronchoscopy) is safe and works well while you receive monitored sedation. If you qualify, it may help improve how breathing is supported during the procedure.
Camden, New JerseyAges 18 years+ - NCT05206331RecruitingPhase 4
Cut biopsy numbers for less concerning breast findings
This study tests a plan meant to reduce how often people get a breast biopsy when the abnormality looks suspicious but not highly worrisome. It may help more people avoid unnecessary procedures while still keeping close medical follow-up.

Study of children with eosinophilic gut disorders
This study looks at children ages 0–18 with eosinophilic gut disorders (EGIDs) to better understand these conditions and how they are managed. It may help doctors improve care by comparing real-world information from patients followed at participating hospitals.

Common questions
- Are there clinical trials for prospective study?
- Yes. Clin2 currently lists 878 recruiting prospective study 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 prospective study 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 prospective study 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.
