This trial studies a personalized plan to remove and re-treat a limited breast recurrence while trying to keep the breast. It may help people whose cancer came back in the same breast after prior breast-conserving treatment, with certain size and spread limits.
Brooklyn, New YorkAges 19–90 - NCT04370730Recruiting
Study brain and symptoms in youth with early psychosis
This study looks at how psychosis symptoms and development change over time in children and teens. It may help doctors better understand different patterns of illness and how to support young people with these disorders.
GentillyAges 7–20 - NCT04381208Recruiting
Using health and movement data to diagnose sacroiliac pain
This study looks at medical records and physical/neurological exam findings to help diagnose sacroiliac joint dysfunction, a common source of chronic low back or buttock pain. It may help your care team better sort out what’s causing your pain and choose the right next steps.
Valencia, ValenciaAges 18 years+ - NCT04383808Recruiting
PET/MRI scan with a small injected tracer
This study tests a new brain PET “insert” that can work at the same time as MRI to create brain images. If you’re healthy and can receive an approved injected tracer (FDG or Neuraceq), you may be able to help confirm the device works safely and clearly.
Palo Alto, CaliforniaAges 21 years+ - NCT04390737RecruitingPhase 1/Phase 2
Study drug HH2853 for hard-to-treat lymphoma and solid cancers
This Phase 1/2 trial tests the safety and early effectiveness of HH2853 in people whose cancer has come back or did not respond to prior treatment. It may help shrink tumors and guide future treatment for specific cancer types and genetic changes.
Phoenix, ArizonaAges 18 years+ - NCT04390308Recruiting
Testing gentle stimulation of ovaries before fertility treatment
This trial studies whether a “mechanical stimulation” procedure can help small egg-making structures in the ovary start to work again in people with primary ovarian insufficiency. If the procedure shows signs of response, you may then move on to further fertility treatment, including IVF.
Abu Dhabi, Abu Dhabi EmirateAges 18–40 - NCT04393389Recruiting
Follow-up study for a drug-coated balloon in leg arteries
This is a post-market follow-up study of a drug-coated balloon used to open blocked leg arteries. It checks how safe the device is and how well it works over time after your procedure.
Halle, Saxony-AnhaltAges 18 years+ - NCT04411823Recruiting
Predicting reflux after stomach sleeve surgery
This trial looks at how to predict who will develop acid reflux after a “stomach sleeve” operation. It may help doctors choose the safest plan before surgery and better prevent reflux afterward.
Orlando, FloridaAges 18 years+ - NCT04420156Recruiting
Study to understand eye disease risk in premature babies
This study looks at newborn eye exams and genetic information to better understand why some premature infants develop a serious vision problem called ROP. You may be invited because your baby needs routine eye screening or is being moved for specialized eye care.
Palo Alto, CaliforniaAges Up to 1 year - NCT04433052Recruiting
Personalized heart-protection program for people at high risk
This trial tests whether a tailored prevention plan can improve outcomes and help with costs for people at high risk of coronary heart disease. You may join if you’ve had recent heart events or scans show significant blockage, and if you can follow the visit and app requirements.
HelsinkiAges 30–80 - NCT04443530Recruiting
Testing Ultimaster stents in everyday patient care
This trial looks at how safe and effective two specific stents are when doctors use them as part of routine care. You may be a candidate if you’re an adult receiving one of these Ultimaster stents and can follow the study check-in schedule.
ChuncheonAges 19 years+ - NCT04458792Recruiting
Builds a cancer blood-and-biomarker database after sarcoma treatment
This study collects information and blood samples from adults with sarcoma who had surgery and possibly radiation. The goal is to build a large dataset that helps researchers understand sarcoma better and improve future care.
Montpellier, HeraultAges 18 years+ - NCT04454892Recruiting
Study of ALS symptoms and disease course
This study watches people with ALS over time to better understand how symptoms change and what features show up. It may help future care and treatments by improving doctors’ understanding of ALS’s natural course.
BeijingAges Any age - NCT04458545RecruitingPhase 1/Phase 2
Opioid vaccine study for adults with heroin or fentanyl use
This trial tests a vaccine made from parts designed to help the body respond to opioids (heroin or fentanyl). It is mainly for adults with moderate-to-severe opioid use disorder who are using opioids that match the study dosing needs and who are willing to do frequent visits over about a year.
Eatontown, New JerseyAges 18–59 - NCT04460235RecruitingPhase 4
Compare two pneumococcal vaccines in adults treated for lymphoma
This trial compares two vaccination plans to see which one works better for preventing pneumococcal infections after lymphoma chemotherapy. You may be randomly assigned to one of the vaccine strategies, and the study checks your immune response.

Testing thicker feeds for babies after unexplained brief events
This trial looks at whether using thicker baby feeds can improve health outcomes for infants who have had their first “brief resolved unexplained event” (a short episode with no clear cause). It may help babies who are being monitored after this first episode.

Common questions
- Are there clinical trials for clinical?
- Yes. Clin2 currently lists 5,620 recruiting clinical 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 clinical 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 clinical 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.
