Recruiting studies
- NCT07257302Recruiting
Breathing muscle training for ALS patients
This study tests whether a special breathing exercise called Lung Insufflation Capacity (LIC) training can help people with ALS maintain or improve their breathing muscle strength. Participants must be age 20 or older, have a confirmed ALS diagnosis, and not be using a breathing machine at the start of the training.
Kodaira, TokyoAges 20 years+ - NCT06756633Recruiting
Breathing and movement study for neuromuscular disease
This study looks at breathing, chest and belly movement, and exercise ability in people with Duchenne Muscular Dystrophy or Spinal Muscular Atrophy, as well as healthy people. The goal is to compare these functions to help understand how these diseases affect the body.
Ankara, ÇankayaAges 5–15 - NCT05061368RecruitingPhase 2
Sildenafil by mouth to improve breathing in COPD
This Phase 2 trial tests whether sildenafil tablets can improve exercise ability, shortness of breath, and heart-lung function in people with COPD. It also compares against people without COPD to better understand how sildenafil affects breathing tests.
Edmonton, AlbertaAges 40–80 - NCT06975982Recruiting
Lung function and frailty in children with esophageal atresia
This study compares breathing, muscle strength, and frailty in children who had esophageal atresia repair with healthy children. It aims to understand how this condition affects lungs and everyday physical abilities.
Ankara, AnkaraAges 6–18 - NCT05595577Recruiting
Personalized exercise program to improve fitness during cancer care
This trial tests whether a tailored, home-based exercise plan can improve exercise capacity (how far and how safely you can be active) in people receiving cancer treatments that may affect the heart. It may help you build safer stamina while monitoring your heart health.
Winston-Salem, North CarolinaAges 18–85 - NCT06193525RecruitingPhase 2
Talazoparib for advanced breast cancer with a DNA repair defect
This trial tests a drug called talazoparib (a PARP inhibitor) for advanced breast cancer that has a specific DNA repair defect (HRD) or a BRCA mutation. The goal is to see if the drug works better when the patient's tumor is tested for this defect just before treatment.
Leiden, South HollandAges 18 years+ - NCT06672497Recruiting
Testing a light sensor for muscle health in breast and gynecological cancer patients
This study uses a safe, non-invasive light sensor (near-infrared spectroscopy) to measure how well your muscles use oxygen. Researchers want to learn if this tool can help monitor muscle health in people with breast or gynecological cancer that has not spread to other parts of the body.
Greenville, South CarolinaAges 20 years+ - NCT04879862Recruiting
Study of walking and bladder recovery after recent spinal injury
This study looks at how leg movement and bladder function change after an acute spinal cord injury. It’s meant for adults who recently injured their spine and cannot stand or move their leg joints on their own.
West Orange, New JerseyAges 18–65 - NCT06069115Recruiting
How radiation affects lung function in breast cancer patients
This study looks at how radiation therapy for breast cancer may affect your lungs over time. Researchers will measure lung function and see if problems develop, so they can better understand and protect patients.
Novosibirsk, Novosibirsk OblastAges 18 years+

Common questions
- Are there clinical trials for functional capacity?
- Yes. Clin2 currently lists 57 recruiting functional capacity 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 functional capacity 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 functional capacity 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.
