Exercise program to support brain function during breast cancer chemo
This trial studies whether a structured exercise program can help protect or improve thinking and memory in people with breast cancer while they are starting chemotherapy after surgery. It may help with “chemo brain” by targeting brain function during treatment.
Toronto, OntarioAges 18–65 - NCT04624490RecruitingPhase 1
Lung function MRI using a special gas in volunteers
This Phase 1 study tests a lung scan that uses a special gas and MRI to measure how well your lungs work. It includes healthy volunteers and people with lung disease to see how well the scan works and how safe it is.
Kansas City, KansasAges 3 years+ - NCT04644094Recruiting
Dexamethasone for heart function after very early birth
This study looks at how giving a steroid medicine (dexamethasone) after very early birth affects the baby’s heart function. It may help doctors better understand risks and benefits for babies who need treatment for serious lung problems.
Montreal, QuebecAges 1 minute+ - NCT04653012Recruiting
Testing brain-activity recordings in people with drug-resistant epilepsy
This study looks at brain activity using electrodes placed inside the brain in people with focal, drug-resistant epilepsy before surgery. It may help doctors better map where seizures start and improve planning for treatment.
ParisAges 18 years+ - NCT04655066Recruiting
Questionnaire study for pelvic floor symptoms during cancer treatment
This study asks people with breast or gynecologic cancer who are receiving cancer treatment to complete a validated questionnaire about how their pelvic floor feels. The goal is to better understand pelvic floor function and symptoms during systemic (whole-body) cancer therapy, which may help future care.
WiesbadenAges 18 years+ - NCT04666103Recruiting
Study of neck anatomy in thyroid surgery
This study looks at how the structures in the neck affect thyroid surgery outcomes. You may be asked about your diagnosis and pre-surgery neck imaging to better understand surgical safety for people with certain thyroid conditions.
Wuhan, HubeiAges 18–75 - NCT04678427Recruiting
Exercise program for kids and young adults in stem cell transplant
This trial tests whether a structured exercise program (“TEAM Me”) can improve movement and mobility during and after a blood stem cell transplant in young people with cancer. It may help reduce stiffness and weakness so you can move more comfortably during treatment.
Dallas, TexasAges 6–29 - NCT04688593Recruiting
Follow-up study of a hip implant cup and stem system
This study looks at how well a specific hip implant (the acetabular cup and femoral stem) works over short, mid, and long-term follow-up. It may help you and other patients by improving understanding of implant outcomes after surgery.
KielAges 18 years+ - NCT04694534Recruiting
Serious game program to help thinking skills in multiple sclerosis
This trial tests whether a computer “serious game” can improve thinking and memory skills in people with multiple sclerosis (MS). It’s designed for adults who report thinking problems and show weaker-than-average results on specific brain tests.
Arras, Hauts-de-FranceAges 18–65 - NCT04706234Recruiting
Check swallowing and voice function in neurodegenerative diseases
This study looks at how well the throat and voice-related functions work in people with certain long-term brain or nerve conditions. It uses a specific throat exam during FEES to better understand swallowing and laryngopharyngeal (throat-area) function.
Innsbruck, TyrolAges 18 years+ - NCT04708613Recruiting
Brain testing study for former football players and controls
This study looks at how the brain and thinking may be affected by playing professional football, using brain scans and thinking tests. It also compares former players with similar men who did not play organized football beyond high school.

Study of health and wellbeing in people with androgen insensitivity
This study looks at the long-term health and wellbeing of people with androgen insensitivity, a genetic condition that affects how the body responds to androgens (male-type hormones). It may help your care team understand what to watch for over time and improve future guidance for patients and families.
Bethesda, MarylandAges 8–99 - NCT04713722Recruiting
Study of early stress and depression using brain imaging
This study looks at how early life stress may be linked to depression, using brain scans. You’ll be asked about your history and asked to do brain imaging to help researchers understand these brain and mood changes.

Study lung immune cells in people at risk for COPD
This study looks at different lung immune cell patterns and how they work in smokers who are not yet diagnosed with COPD or asthma. It may help researchers understand why some people are more likely to develop COPD, which could guide future prevention or early treatments.

Common questions
- Are there clinical trials for function?
- Yes. Clin2 currently lists 2,557 recruiting function 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 function 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 function 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.
