Recruiting studies
- NCT06821126RecruitingPhase 1/Phase 2
Nasal spray COVID-19 vaccine booster study for healthy adults
This study tests a new nasal spray COVID-19 vaccine to see how it compares to an mRNA booster shot. It is for healthy adults who have already had at least 3 doses of an mRNA COVID-19 vaccine (or 2 doses plus a confirmed COVID infection) and are looking for a needle-free booster option.

Roslindale, MassachusettsAges 65–90 - NCT06817421RecruitingPhase 4
Pneumococcal vaccine for children with severe malnutrition
This study tests whether giving the pneumococcal vaccine during hospitalization for severe malnutrition can help prevent infections. It may help protect your child from serious illness.
DiliAges 6 months–4.9 years - NCT06818084RecruitingPhase 4
TAVR for severe aortic regurgitation using VitaFlow Liberty
This trial tests the VitaFlow Liberty device, a catheter-based treatment for people with severe aortic regurgitation (a leaky heart valve). If you have symptoms or your heart is starting to weaken, this procedure might help avoid open-heart surgery.
Shanghai, Shanghai MunicipalityAges 60 years+ - NCT06817889RecruitingPhase 2
Remdesivir for RSV in people with weak immune systems
This trial tests if remdesivir can safely treat RSV (a respiratory virus) in people with weakened immune systems, such as those who have had a stem cell or bone marrow transplant, CAR T-cell therapy, or are being treated for blood cancer. If you have a confirmed RSV infection in your nose or throat and are at moderate or high risk for complications, you may be able to join.
Duarte, CaliforniaAges 18 years+ - NCT06819683RecruitingPhase 1
Testing a new oxygen sensor in people with and without mitochondrial myopathy
This study tests a tiny sensor that measures oxygen levels in muscle. It will help researchers understand how oxygen is used during exercise. If you have mitochondrial myopathy or are a healthy volunteer, you might be able to join.
Philadelphia, PennsylvaniaAges 18–65 - NCT06821191RecruitingPhase 4
Safer blood thinner plan after heart stent
This trial is testing whether lowering the dose of your current blood thinner or switching to a different one (clopidogrel) is safer and works just as well after you've had a stent placed. It's designed for people who are already on two blood thinners and are doing well.
Jacksonville, FloridaAges 18 years+ - NCT06825390Recruiting
Ear stimulation and brain imaging for chronic low back pain
This study tests if a non-invasive ear stimulation technique can change brain activity linked to chronic low back pain. You would have a brain scan before and after the treatment to see how your brain responds.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06822231Recruiting
High-tech rehab for acute neuromuscular diseases
This study tests a high-tech rehab program using robots and advanced tools to help people recover from acute neuromuscular diseases. It aims to see if this approach improves leg strength and mobility better than standard care.
BariAges 18–80 - NCT06817031Enrolling by invitationPhase 2
Probiotics for gut health in pregnancy – Bangladesh study
This study tests whether a daily probiotic capsule during pregnancy can improve the health of a mother's gut, especially if she is exposed to unclean water or poor sanitation. Pregnant women early in their second trimester who live in the Matlab area of Bangladesh may join.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,409 recruiting 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 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 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.
