Dapagliflozin for kidney disease to improve heart structure
This Phase 2 study tests whether dapagliflozin can improve heart structure and function in people with chronic kidney disease (CKD). Dapagliflozin is a kidney-heart medicine that may affect how the heart changes over time, measured by heart scans.

Noninvasive spinal stimulation to improve bladder and autonomic function
This trial tests a noninvasive way to stimulate the spinal cord to help the body’s “automatic functions” (like bladder, bowel, and sexual function) after spinal cord injury. If you’ve had a stable, complete spinal cord injury for more than a year, you may be eligible to try this approach and help researchers evaluate recovery.
Vancouver, British ColumbiaAges 19–60 - NCT05376254Recruiting
3D heart scan study during LVAD implantation
This study uses special 3D heart imaging to better measure right-heart function during LVAD surgery. It may help doctors understand how the right side of the heart responds when a mechanical pump is put in.
Edmonton, AlbertaAges 16 years+ - NCT05386615Recruiting
Pregnancy follow-up registry after Exablate for fibroids

Waterloo, OntarioAges 18–39 - NCT05396352Recruiting
Study brain-task skills in autism using brain stimulation
This study looks at how different brain regions work in people with autism and in neurotypical adults using thinking tasks, MRI scans, and a noninvasive brain stimulation called tDCS. It may help researchers better understand social and executive thinking—how you plan and manage tasks.
Washington D.C., District of ColumbiaAges 18–35 - NCT05400499Recruiting
Deep brain stimulation study in Parkinson’s visuomotor function
This trial studies how deep brain stimulation affects hand-eye (visuomotor) coordination in people with Parkinson’s. It may help researchers understand whether the stimulation settings change movement control for daily tasks.
Cleveland, OhioAges Any age - NCT05402488Recruiting
Studying sleep recovery in adults with neurodegeneration
This study looks at how sleep “recovery” works in people with neurodegenerative diseases (conditions where abnormal proteins build up). It uses sleep recordings and sounds during sleep to see how sleep patterns relate to outcomes.
Zurich, Canton of ZurichAges 18 years+ - NCT05413616Recruiting
Personalized nutrition and activity therapy for older hospital patients
This study tests whether a tailored nutrition plan plus a step-by-step exercise program can improve physical strength and performance in older adults in the hospital. It compares these interventions to the usual hospital care you would normally get.
Nijmegen, GelderlandAges 65 years+ - NCT05414357Recruiting
Sleep problems study in breast cancer and effects on thinking
This study looks at how sleep problems affect thinking and daily quality of life in people treated for early breast cancer. It may help researchers understand which sleep issues to target to improve well-being during or after treatment.
CaenAges 45–65 - NCT05421325RecruitingPhase 2
Vaccine-like immune treatment to prevent lung infections in seniors
This Phase 2 study tests a site-specific immune “booster” in people age 65 and older to help improve natural immunity and reduce respiratory (lung/airway) infections. You may be eligible if you can consent, are in an eligible living situation, and are not currently using certain immune-suppressing medicines.
Burnaby, British ColumbiaAges 65 years+ - NCT05427136Recruiting
Study early lung problems after childhood cancer treatment
This study looks for early lung (breathing) problems in children after certain cancer treatments, using lung tests and sometimes MRI scans. It may help doctors spot breathing complications earlier and guide better care.
BaselAges 4–22 - NCT05443633Recruiting
Brain and speech training for people with aphasia
This study looks at ways to improve language (speaking and understanding) for people with aphasia caused by stroke or dementia, using MRI to study brain function. It may help by testing language-focused approaches and how brain activity changes during treatment.
Tucson, ArizonaAges 21–80 - NCT05445180Recruiting
Brain scan study of thinking in cannabis users with psychosis
This study uses brain imaging to understand how thinking works in people who use cannabis, comparing those with psychosis to people without psychosis. It may help researchers learn what brain patterns relate to thinking difficulties and how cannabis use fits in.
Montreal, QuebecAges 16–80 - NCT05445960Recruiting
Tourniquet use during ankle surgery and recovery outcomes
This study looks at whether using a tourniquet during ankle fracture surgery affects healing, leg movement, and patient-reported recovery. It may help doctors choose the safest, most comfortable approach for surgery.
Portland, OregonAges 18–89 - NCT05459090Recruiting
Study of how brain “brakes” work in drug-resistant temporal epilepsy
This study looks at how the brain’s natural “braking” system works in people with drug-resistant temporal lobe epilepsy. It may help researchers better understand the condition in order to improve future treatments.
Pozzilli, IserniaAges Any age - NCT05459116Recruiting
Record breathing effort to protect lungs during ventilation
This trial studies a way to measure how hard a patient is breathing and how the lungs and diaphragm are working while someone is on a breathing machine. The goal is to help the team use a “lung- and diaphragm-protective” ventilation strategy and see if it improves care.
Edegem, AntwerpAges 4 weeks+ - NCT05467215RecruitingEarly Phase 1
Brief oxygen breathing trial after spinal cord injury
This early-phase study tests whether a short period of breathing extra oxygen (hyperoxia) soon after lying in one position can improve physical function in people with long-term spinal cord injury. If you qualify, the goal is to see whether this treatment can help your body work better after chronic injury.
Edmonton, AlbertaAges 18–65 - NCT05468255Recruiting
Study how stopping exercise affects blood sugar and blood vessels
This study looks at what happens to blood sugar levels and blood vessel health when active adults stop exercising. It may help doctors understand how quickly these changes can happen and who may be most affected.
Norfolk, VirginiaAges Any age - NCT05473520RecruitingPhase 3
Doxycycline add-on therapy for lung improvement in tuberculosis
This Phase 3 trial tests whether adding doxycycline to standard TB medicine can improve lung function and reduce lung tissue damage. It aims to see if patients recover better by targeting the lung response to TB.

How sugar swings may affect brain and eating in type 1 diabetes
This study looks at whether changes in blood sugar (“sugar swings”) affect brain functioning and eating behaviors in adults with type 1 diabetes. You would likely track your blood sugar and complete computer-based tasks or questionnaires to help researchers understand these links.

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.
