Boston, MassachusettsAges 55–90 - NCT05793177Recruiting
Monitoring light movement after stroke rehabilitation
This study checks whether tracking sitting time and light activity after stroke is helpful for recovery during rehabilitation. You would be monitored for daily movement, and the researchers want to see how activity patterns relate to recovery.
RoskildeAges Any age - NCT05802680Recruiting
Near-infrared light study for brain effects in adults
This study tests how non-invasive near-infrared light may affect brain function. You may be able to join if you’re an adult, since there are no other listed eligibility restrictions.
Austin, TexasAges 18 years+ - NCT05875870Recruiting
Bright light and exercise program for lung or esophageal cancer
This trial tests whether a structured bright-light exposure routine combined with a specific exercise program can help people with newly diagnosed lung or esophageal cancer. You may be eligible if you’re in early-to-middle cancer stages and able to safely participate in walking-based activities.
Taipei City, TaipeiAges 20 years+ - NCT05884944Recruiting
Osteopathic massage study for leg muscle in Parkinson’s disease

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+ - NCT05913063Recruiting
Testing how the eye responds to tiny quantum states
This study looks at how the human eye detects very small “quantum” information. It compares people with certain vision conditions to people with normal vision to see how the eye’s macula and overall vision are involved.
Hong Kong, GuangdongAges 18 years+ - NCT05917119Recruiting
Bright light therapy for obstructive sleep apnea symptoms
This study tests whether a “bright light” treatment can reduce daytime sleepiness in people with obstructive sleep apnea who are already using CPAP or BiPAP. It may help people feel more awake during the day without changing their sleep apnea device use.
Pittsburgh, PennsylvaniaAges 40–65 - NCT06006637Recruiting
Measuring and reducing autism symptoms
This study tests a new platform designed to measure and reduce autism symptoms in children ages 2 to 8. It may help if your child has an autism diagnosis and is not taking psychiatric medications.
New York, New YorkAges 2–8 - NCT06045897Recruiting
EEG brain test for young people at risk of psychosis
This study uses a short EEG recording to look at brain activity patterns in young people with early signs of mental health conditions, including those at risk for psychosis, first episode psychosis, depression, or autism. It aims to find brain markers that could help identify people who might benefit from early treatment.
ParisAges 15–30 - NCT06071637RecruitingPhase 3
Preventing mouth sores with laser therapy in stem cell transplant
This trial tests if a low-power laser can prevent painful mouth sores and throat pain in people getting a stem cell transplant from a donor. The laser is applied to the mouth before sores start, aiming to reduce pain and speed healing.
Rio de Janeiro, Rio de JaneiroAges 18–100 - NCT06092411Recruiting
CBT and light therapy for depressed youth who are night owls
This trial tests if combining cognitive behavioral therapy (CBT) with bright light therapy (BLT) helps Chinese teenagers and young adults who have depression and a natural tendency to stay up late. The goal is to improve mood and sleep patterns.
Hong KongAges 12–20 - NCT06120361Recruiting
Primary care study for early cognitive decline
This research study looks at people who have noticed problems with memory or thinking (like trouble focusing or finding words) and visit their primary care doctor for help. It aims to better understand and diagnose conditions that cause these symptoms, such as Alzheimer's disease.

Electric vs. Manual Toothbrush for Kids with Cleft Lip/Palate
This study compares a special dual-light electric toothbrush to a regular manual toothbrush for kids and teens with cleft lip or palate who wear braces. The goal is to see which brush keeps teeth cleaner and gums healthier during orthodontic treatment and after oral surgery.
Los Angeles, CaliforniaAges 6–20 - NCT06122415Recruiting
Memory clinic study with fluid and cognitive tests
This study looks at people who are being checked for memory or thinking problems. It uses standard tests done at the memory clinic, like a spinal tap and blood draw, plus memory and thinking tests, to learn more about these symptoms. You can join if these tests are already planned as part of your regular care, even if you don't take part in the study.
MalmöAges Any age - NCT06205953Recruiting

- How do I know if I qualify for a light 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 light 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.
