Muscular atrophy

This phase 2 trial tests whether a patient's own fat-derived cells (stromal vascular fraction) can improve healing after surgical repair of a chronic rotator cuff tear. The study enrolls 56 adults aged 45-65 with full-thickness tears who have not improved with physical therapy. T…

This trial tests the long-term safety and effectiveness of apitegromab, an investigational antibody that blocks myostatin, a protein that limits muscle growth. People with type 2 or type 3 spinal muscular atrophy who completed earlier apitegromab studies can join. Researchers wil…

This early-phase trial tests whether injecting special donor cells (E-CEL UVEC) into the shoulder during rotator cuff surgery is safe and might improve healing. Twenty adults aged 45-70 with full-thickness tears will receive the cells at the repair site. The main goal is to check…

This study follows 175 people with spinal muscular atrophy who previously received the gene therapy Zolgensma in clinical trials. Researchers will monitor them for 5 years to track serious side effects and developmental milestones. The goal is to understand how safe and effective…

This pilot study tests whether metformin, a common diabetes drug, can help older adults recover muscle and function after a hip fracture. Sixty people aged 60 and older will take either metformin or a placebo daily for 4 months after surgery. The main goal is to see if the study …

This study tests a special body suit that uses gentle electric pulses to stimulate muscles, helping astronauts exercise more efficiently in space. Twelve astronauts on the International Space Station will wear the suit during their workouts. Researchers will measure muscle stiffn…

This early-phase trial tests whether metformin, a widely used diabetes drug, can prevent muscle loss and insulin resistance in healthy older adults during five days of bed rest. Researchers will measure changes in muscle size and insulin sensitivity. The study involves 64 partici…

This pilot study is testing the drug tirzepatide (Zepbound) in 40 older adults with obesity to see how it affects body composition, bone density, and physical function over nine months. Participants take weekly injections, track their diet and activity, and attend regular check-i…

People with muscle disease often have high levels of a heart protein called troponin, even when their heart is fine. This can make it hard for doctors to tell if chest pain is a heart attack. Researchers are comparing two types of troponin tests in patients with and without muscl…

This study tests a home monitoring program called LiverWatch for people with advanced liver disease (cirrhosis). Participants get a Fitbit, personalized nutrition advice, and weekly check-ins to boost activity and manage symptoms. The goal is to see if this approach improves qual…

This pilot study tests the drug ruxolitinib in people with advanced non-small cell lung cancer who are experiencing cancer cachexia—unintended weight loss and muscle wasting. The main goal is to check for side effects and see how the drug affects body signals related to appetite …

This study tests whether a neuromuscular electrical stimulation (NMES) device, used alongside standard physical therapy, can help people regain muscle strength more quickly after ACL reconstruction surgery. Twenty-five participants aged 15 to 50 will use the Zynex NexWave device …

This pilot study tests whether adding blood flow restriction therapy to standard physical therapy helps elderly patients (65 and older) recover muscle strength and size after hip fracture surgery. Twenty participants will have their thigh and leg measurements, muscle strength, pa…

This study tests whether a combination of exercise, fruit, and vitamin supplements can reduce frailty in older adults aged 65 to 80. About 934 participants with low physical activity and low fruit intake will be split into two groups: one receives the combined intervention three …

This study explores whether adding motor imagery (mentally practicing shoulder movements) to standard physical therapy improves muscle activity, pain, and function after arthroscopic rotator cuff repair. About 36 adults who have had this surgery will be split into two groups: one…

This study looks at how middle-aged men and women lose muscle after a week of not using one leg, and how they recover with exercise. Researchers will measure muscle strength, size, and genetic activity to find sex-specific differences. The goal is to learn more so future treatmen…

This study looks at 100 people who spent at least a week in the ICU and had kidney injury. Researchers will measure kidney function, muscle loss, and bone health to understand long-term effects. The goal is to improve follow-up care for ICU survivors.

This study looks at how CFTR modulators, a type of cystic fibrosis treatment, affect bone strength and muscle mass in adults with CF. Researchers will measure changes in bone density and lean body mass over 12 to 24 months. The goal is to understand whether these treatments help …
