Recruiting studies
- NCT05799118Recruiting
Genetic modifiers study for inherited blood disorders
This study looks at how your genes can affect inherited blood conditions like sickle cell disease and thalassemia. It may help researchers understand why symptoms differ from person to person, which could guide better future treatments.
Boston, MassachusettsAges 2 years+ - NCT05800028Recruiting
Study brain scans and social life in memory changes
This study looks at how memory and brain function relate to social interactions. It focuses on people with probable Alzheimer’s disease or a specific language-related condition, and on healthy partners matched by age and social background.
CaenAges 18–85 - NCT05800210RecruitingPhase 2
T cell and B cell immune “wipeout” after stem cell transplant
This Phase 2 trial studies whether removing certain immune cells (alpha/beta T cells and CD19+ B cells) around the time of a stem cell transplant can improve outcomes for people with high-risk blood cancers. It may help by reducing the immune responses that can interfere with the transplant working, while keeping the process safe.
Gainesville, FloridaAges 6 months–39 years - NCT05800821Recruiting
Predicting brain blood-flow problems after carotid surgery
This study uses deep learning to predict which people are at risk for “cerebral hyperperfusion syndrome” (a dangerous spike in brain blood flow) after carotid revascularization. If you qualify, they’ll use scans/tests to estimate your risk so doctors can watch you more closely if needed.
MinskAges 30–80 - NCT05802121RecruitingEarly Phase 1
Testing a gut bacteria supplement side effects during prostate hormone therapy
This early-phase study looks at how changing gut bacteria (especially Akkermansia) affects metabolic side effects in men starting prostate hormone therapy (ADT). It may help researchers understand how to reduce or manage side effects for people on ADT.
London, OntarioAges 18 years+ - NCT05802407Recruiting
ctDNA blood test monitoring after pancreatic cancer surgery
This study looks at whether a special blood test (ctDNA) can detect tiny amounts of pancreatic cancer left after surgery. It may help doctors monitor who is at higher risk of cancer coming back, so they can tailor follow-up and treatment timing.
BeijingAges 18 years+ - NCT05802394Recruiting
Using blood tests to track cancer after pancreatic treatment
This trial studies whether a blood test (ctDNA, a DNA signal from tumors) can help track how pancreatic cancer responds during planned conversion therapy. It may help doctors spot treatment response earlier and guide next steps.
BeijingAges 18 years+ - NCT05805631RecruitingPhase 2
Pemetrexed into spinal fluid for EGFR-mutant lung cancer spread to brain lining
This Phase 2 trial tests giving pemetrexed directly into the spinal fluid to treat cancer that has spread to the brain’s and spinal cord’s lining (leptomeningeal metastasis). It is for people with EGFR-mutant non-squamous lung cancer whose disease progressed after osimertinib, and who may benefit from a targeted treatment delivered to the area affected in the brain lining.
Taipei, TaiwanAges 20 years+ - NCT05805605RecruitingPhase 2
Low-intensity stem cell transplant with donor cells and blood-protection
This Phase 2 study tests a low-intensity bone marrow/stem cell transplant using a matched donor plus two medicines to help prevent the donor cells from attacking you. It aims to treat certain blood cancers—especially when standard treatment has not fully worked or when you are in remission but at higher risk.
Minneapolis, MinnesotaAges Up to 75 years - NCT05806801Recruiting
Study how weight loss changes the body with or without exercise
This study looks at how your metabolism (how your body uses energy and controls blood sugar/fats) changes during weight loss, comparing weight loss alone versus weight loss plus exercise. It may help researchers understand what body changes happen with different approaches and why.
Ann Arbor, MichiganAges 18–40 - NCT05806697Recruiting
Study of brain scan clues in people worried about memory
This extension study looks for predictors—measurable clues—linked to memory changes in older adults who feel their memory is worsening. You may be asked to have an amyloid PET scan, which can help researchers understand what might be driving memory concerns.
Paris, Île-de-France RegionAges 70–95 - NCT05807841Recruiting
AI ultrasound during stent placement in heart artery blockages
This trial tests an artificial-intelligence tool that uses a heart ultrasound to help guide stent treatment. It may help doctors choose the best way to treat blockages and improve stent results for people with symptoms from reduced blood flow to the heart.
Bucheon-siAges 19 years+ - NCT05807932RecruitingPhase 1/Phase 2
Venetoclax added to conditioning before stem cell transplant
This trial tests adding venetoclax to a standard “conditioning” chemotherapy plan before an allogeneic stem cell transplant (using a donor) for certain bone marrow cancers. It aims to improve how well the transplant works and how safe this combination is for people with MDS, CMML, or sAML.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT05809310Recruiting
Stenting branches to improve blood flow after certain heart repairs
This study looks at whether placing a small tube (stent) in a branch pulmonary artery can improve blood flow and heart function after specific childhood heart surgeries. It is meant for people who have d-TGA after ASO, or have ToF or TA, and need a branch PA intervention.
AmsterdamAges 8 years+ - NCT05812963Recruiting
IVUS vs FFR to guide stents after heart attacks
This trial compares two ways of measuring blood flow inside the heart arteries (IVUS vs FFR) to help decide which non–culprit artery narrowings need a stent after a recent heart attack. It may help doctors choose the best targets for PCI and avoid unnecessary procedures.
GwangjuAges 19 years+ - NCT05814237Recruiting
Study of new respiratory infections starting within 10 days
This is an observational study that follows adults who are newly sick with a respiratory infection that started within the past 10 days. It may help researchers understand what causes these infections and how patients do in emergency or hospital-care settings.
BrusselsAges 18 years+ - NCT05814952Recruiting
LX103 eye treatment for X-linked retinoschisis
This trial studies whether LX103 can improve vision and is safe for people with X-linked retinoschisis (XLRS) caused by RS1 gene changes. It focuses on a specific level of vision in the study eye and checks for medical conditions that could affect eye testing or safety.
ShanghaiAges 6 years+ - NCT05817734Recruiting

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 recruiting general population (no specific condition or 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 general population (no specific condition or 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 general population (no specific condition or 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.
