Recruiting studies
- NCT07111572Recruiting
Can gut markers show early if a UC treatment works?
This study looks at stool samples to see if certain markers can quickly tell whether a biologic medicine is starting to work for moderate-to-severe ulcerative colitis. If successful, this could help doctors make faster, smarter treatment decisions.
Jinan, ShandongAges 18–75 - NCT07649525RecruitingPhase 3
Personalized myeloma treatment based on response and fitness
This trial tests whether tailoring myeloma treatment based on how well you respond to initial therapy and your overall health status can improve outcomes. You'll receive standard first-line treatment (three drugs: daratumumab, lenalidomide, and dexamethasone) and then be assigned to a personalized pathway based on your response and fitness level.
BristolAges 18 years+ - NCT04078243Recruiting
Trial setup and testing in adults with pulmonary hypertension
This study tests new “trial tools” and designs for running early research in people with pulmonary hypertension. If you qualify, you may be asked to do extra trial-related procedures to help researchers test the process safely and smoothly.
Sheffield, South YorkshireAges 18 years+ - NCT04081896Recruiting
Rehab program for adults with spine pain
This trial studies whether a prescribed physical therapy (rehab) program helps people with spine pain. It may help by improving pain and function when a clinician has already recommended rehabilitation.
San Diego, CaliforniaAges 18–89 - NCT04570020Recruiting
Check how well wide-view scans guide scleral lens fitting

Tuscaloosa, AlabamaAges 40 years+ - NCT04754672Recruiting
Exercise training to improve outcomes in advanced colon cancer
This trial studies whether supervised exercise—either aerobic fitness training or muscle-strength training—can improve outcomes for people with metastatic colorectal cancer. It compares which approach is most helpful and checks whether it’s safe during first-line chemotherapy.
's-HertogenboschAges 18 years+ - NCT04791371Recruiting
Study how fitness and insulin resistance relate to diabetes
This study looks at how low physical activity, insulin resistance in small blood vessels, and cardiorespiratory fitness connect to diabetes and blood sugar control. You may be eligible if you are generally sedentary and fit within the weight range, and if you do not have certain heart, lung, nerve, or medication factors.
Aurora, ColoradoAges 30–55 - NCT04916340Recruiting
Exercise program study for heart blood vessel function and anxiety
This study tests whether an exercise training program can improve how well blood vessels work in people with PTSD or generalized anxiety. You may be placed into a PTSD, GAD, or healthy control group based on questionnaire scores.
Richmond, VirginiaAges 18–35 - NCT04946448Recruiting
Test a Crohn’s diet and biologic medicine combination
This study tests whether combining a specific diet with biologic medicines can reduce active inflammation and symptoms of Crohn’s disease. It may help people who still have active disease in the bowel despite prior care.
LeuvenAges 18–80 - NCT04967183Recruiting
Compare a stool blood test versus colonoscopy follow-up after precancer removal
This study compares two ways of checking for colorectal cancer risk after advanced polyps are removed. It may help determine whether a stool test can safely replace some colonoscopy surveillance for certain people.
OurenseAges 50–65 - NCT05009433Recruiting
Exercise plans in pregnancy and afterward for mom and baby health
This study compares two types of exercise—short, intense intervals versus moderate steady activity—during pregnancy and looks at effects on mothers and children. It also checks how participants do on health, fitness, and well-being tests before, during, and after pregnancy.
Gdansk, Pomeranian VoivodeshipAges 18–45 - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05025774Recruiting
Exercise program study for young heart, leukemia, and lung survivors
This study looks at how an exercise program affects fitness and lung function in young people who are survivors of certain conditions (heart transplant, leukemia, or lung disease from prematurity). The goal is to see whether exercise can improve breathing and overall physical function safely.
Minneapolis, MinnesotaAges 8–25 - NCT05100966Recruiting
Exercise program for people waiting for hip or knee replacement
This trial tests a “getting fit” program to help people who are somewhat frail before hip or knee replacement surgery. It aims to improve fitness while you wait for surgery, which may help you feel stronger for recovery.
Calgary, AlbertaAges 60 years+ - NCT05194397RecruitingPhase 2
Exercise plus NR supplement to boost fitness after stem-cell transplant
This trial tests whether a supervised exercise program, plus an NR supplement, can improve fitness in young people who have had an allogeneic (donor) stem-cell transplant for certain blood cancers or bone marrow conditions. It’s meant to help with energy and physical ability while monitoring safety.
Duarte, CaliforniaAges 10–30 - NCT05218083Recruiting
Mobile rehab program with interval exercise after COVID-19
This trial tests a coach-supported, phone-based rehabilitation program that includes high-intensity interval-style exercise for people recovering from COVID-19 after a hospital stay. It may help improve breathing, strength, and walking by providing structured exercise at home.
Birmingham, AlabamaAges 18 years+ - NCT05267665Recruiting
Family-involved PTSD therapy coaching for Veterans
This study tests a brief way to include a Veteran’s family member to improve PTSD treatment results and help people stay engaged in care. It’s for Veterans who are just starting evidence-based PTSD therapy and have a closely involved family member who can participate too.
Boston, MassachusettsAges 18 years+ - NCT05277935Recruiting
Wearable activity tracking for hormone-positive metastatic breast cancer
This study tests whether using a wearable watch and smartphone app to track activity and fitness can help monitor health in people with hormone receptor–positive, HER2-negative metastatic breast cancer while they take standard hormone therapy plus palbociclib. It mainly requires that you are already on these medicines for at least three months and can use the devices reliably.
Rio de JaneiroAges 18 years+ - NCT05332457Recruiting
Beta-blocker effects on heart rate and exercise capacity in atrial fibrillation
This study looks at how taking a beta-blocker affects your resting heart rate during activity and how fit your heart and lungs are during an exercise test. It may help clarify whether the way the medication controls heart rate is linked to better exercise tolerance in people with persistent atrial fibrillation.
TaipeiAges 20 years+ - NCT05394363Recruiting
Victoria children birth-cohort study with parent/guardian consent
This study follows children born in a specific 2-year window and their parents or guardians over time. It helps researchers understand how children and families change as they grow, which can guide future health supports in Victoria.

Common questions
- Are there clinical trials for fit?
- Yes. Clin2 currently lists 255 recruiting fit 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 fit 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 fit 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.
