Recruiting studies
- NCT04284397RecruitingEarly Phase 1
Study of safe temperature conditions for adults
This early study looks at which hot or cold environments are safest and most challenging for adults who don’t have symptoms of disease. It may help improve safety guidelines so older adults can exercise or be exposed to temperature changes more safely.

iPS cell eye transplant for dry macular degeneration
This early-phase study tests whether transplanting lab-made retinal cells from your own body can slow vision loss from geographic atrophy caused by dry age-related macular degeneration. It involves eye surgery and frequent follow-up to check safety and early signs of benefit.
Baltimore, MarylandAges 55–95 - NCT04792554Recruiting
Study of aging around major non-heart surgery
This study looks at changes in health and function in older adults before and after major surgery. It may help doctors understand how “aging” affects recovery and what could improve outcomes.
SingaporeAges 65–100 - NCT04796545Recruiting
Implant study for late macular degeneration with cataracts
This post-market study looks at how well a telescope-like eye implant (NG SI IMT 3X) works for people with very advanced age-related macular degeneration that affects the center of vision, plus cataracts. The implant is placed in one eye, and you’ll get training to learn how to use it after surgery.
BrusselsAges 55 years+ - NCT05028309Recruiting
Study how obesity affects breathing and exercise in older adults
This study compares how body weight (higher or lower body fat) affects lung function, breathing during exercise, and exercise capacity in adults ages 65–75. You may be asked to do lung and exercise testing, but only if you meet health and activity restrictions.
Dallas, TexasAges 65–75 - NCT05296980Recruiting
Testing a dementia risk-reduction program for older adults
This study checks whether a program called REMINDER can help reduce risk of developing dementia by improving risk factors over 12 weeks. It’s for older adults who have higher dementia risk but do not currently have dementia.
CoimbraAges 60–75 - NCT05322343Recruiting
Study biobank and brain health in people age 55–80
This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
Bordeaux, BordeauxAges 55–80 - NCT05457725Recruiting
Study how aging affects learning to trust and distrust
This study looks at how thinking and learning processes change with age, especially around deciding what to trust. You may be asked to complete computer tasks and brief memory/thinking tests to understand these changes.
Gainesville, FloridaAges 18–100 - NCT05468905Recruiting
Study of aging and early thinking changes over time
This study follows adults 40+ to better understand and track changes in memory and thinking as people age. It groups people with normal thinking, subjective complaints, mild cognitive impairment, early Alzheimer’s, and vascular (blood vessel) related brain changes to find what predicts progression.
Hangzhou, ZhejiangAges 40–99 - NCT05493241Recruiting
Behavior therapy to help older veterans stay independent
This study tests a behavior-change program (called Behavioral Activation) to help older veterans keep their independence and daily functioning. It may help if you’re at risk of getting weaker or less able to do everyday activities.
Bedford, MassachusettsAges 65 years+ - NCT05574634Recruiting
Study of brain signaling and distraction in aging adults
This study looks at how a deep brain area helps people focus and ignore distractions as we get older. You may be invited if you’re a healthy adult and can safely complete brain-related testing.
Blacksburg, VirginiaAges 18–75 - NCT05824234Recruiting
REFOCUS program for mental health care teams
This trial tests whether a training program for mental health teams improves care for people with certain mental health conditions. You may be included if your clinic/team is using the REFOCUS training and you meet the study language and consent requirements.
Lyon, RhôneAges 15–65 - NCT05926219Recruiting
Study C-protein changes with fatigue and aging
This study looks at how a blood protein called C-protein relates to fatigue and aging, and how exercise affects it. You may be able to join if you’re otherwise healthy and willing to do muscle testing and activity monitoring.
Eugene, OregonAges 18–80 - NCT05999604RecruitingPhase 3
Yearly vs every-6-month infusions for active MS
This study compares receiving ocrelizumab infusions every 6 months versus once a year for people with active MS who have already been on treatment for 2 years. The goal is to see if yearly infusions work just as well to keep the disease quiet on MRI scans.
CréteilAges 18 years+ - NCT06044623RecruitingPhase 3
Tailoring cancer pill dosing for older adults with breast cancer
This trial is testing whether adjusting the dose of a targeted therapy (CDK 4/6 inhibitor) based on a geriatric assessment can be as effective and safer for people aged 70 and older with advanced hormone receptor-positive, HER2-negative breast cancer. It aims to find the best dose to balance benefits and side effects.
HelsinkiAges 70 years+ - NCT06052332Recruiting
Comparing two pre-surgery treatments for older adults with rectal cancer
This study compares two approaches to treating rectal cancer in people age 70 and older who have not yet had surgery. One approach gives chemotherapy and radiation before surgery, and the other adds more chemotherapy after radiation. The goal is to find which plan works better with fewer side effects.
Antwerp, AntwerpenAges 70 years+ - NCT06052605Recruiting

Preventing frailty in older adults with chronic conditions
This study tests if a personalized prevention program based on a full health check (comprehensive geriatric assessment) can help prevent frailty in older adults who already have at least one long-term health condition (like heart disease, diabetes, or arthritis). If it works, the program could keep you stronger and healthier longer.
