It may help control disease more effectively and improve response duration for eligible patients.
Tucson, ArizonaAges 18 years+ - NCT05894070Recruiting
Using your voice recordings to spot cancer coming back
This study looks at whether changes in your voice can help detect early return of laryngeal or hypopharyngeal cancer. If you’ve finished curative treatment and are disease-free for a certain period, your voice will be monitored to see if it can signal recurrence sooner.
BernAges 18 years+ - NCT05898646RecruitingPhase 2
Daratumumab maintenance for AL amyloidosis after initial treatment
This Phase 2 trial studies whether giving daratumumab as ongoing maintenance therapy after your initial AL amyloidosis treatment can improve survival. It may help by keeping the disease under control longer after you have responded to induction therapy.
Scottsdale, ArizonaAges 18 years+ - NCT05903001Recruiting
Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT05916040Recruiting
MRI-guided treatment for locally advanced rectal cancer
This trial studies a total “before-surgery” treatment plan for locally advanced rectal cancer, using MRI (a detailed scan) to help guide radiation. It may help patients by aiming to shrink the tumor and improve the chance of successful surgery.
Jette, Brussels CapitalAges 18 years+ - NCT05924425RecruitingPhase 4
Daridorexant for insomnia in early memory decline
This trial tests whether daridorexant can improve sleep in people who have mild cognitive impairment or early Alzheimer’s disease and struggle with insomnia. It may help by improving how long and how well you sleep, with monitoring of sleep patterns and memory-related measures.
MontpellierAges 60–85 - NCT05924295Recruiting
Study how ketone changes in the body with diet and fasting
This study looks at how your body processes “ketones,” which are energy molecules that rise with fasting or low carbohydrate intake. You may be asked to follow strict diet and activity rules before test days so researchers can see what affects ketone metabolism.
Novato, CaliforniaAges 20–70 - NCT05930496Recruiting
Exercise after colorectal cancer to change gut bacteria
This study tests whether a structured exercise program can improve the makeup of gut microbiota (gut bacteria) in people who have finished treatment for stage II–III colorectal cancer. It may help learn how exercise supports recovery, and it involves remote or in-person sessions with gut-focused tracking.
Seattle, WashingtonAges 18–70 - NCT05937334Recruiting
Long-term study of asthma in adults in China
This study follows adults with asthma over about 2 years to learn more about asthma and how people do over time. If you qualify, you’ll be asked to join regular visits and follow the study plan.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05941182Recruiting
Remote eye follow-up using Vision self-testing
This trial looks at a real-world way to run remote (video/online) eye clinic follow-up visits that include self-testing. It may help your care be more convenient while still supporting proper eye checks from home.
Cambridge, CambridgeshireAges 4 years+ - NCT05942885Recruiting

Portland, OregonAges 18 years+ - NCT05943652Recruiting
Study of how functional overlay affects movement disorders
This study looks at movement disorders that are functional (not caused by damage to the nervous system) or non-functional, and how a “functional overlay” may change symptoms. It is observational, meaning it does not test a new treatment, but it may help researchers better understand these differences and improve care.
Graz, StyriaAges 18–18 - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Birmingham, AlabamaAges 18 years+ - NCT05947149Recruiting
Quality-of-life study in head and neck cancer after hadrontherapy
This study asks people with certain head and neck cancers (or long-term survivors) about how hadrontherapy affected their quality of life. It may help doctors understand long-term wellbeing and care needs after treatment.
Pavia, PvAges 18 years+ - NCT05950698Recruiting
