Recruiting studies
- NCT05444127Recruiting
Study of oral health in people with Wilson’s disease

Blood test study to track markers in diabetes
This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.

How cues affect drinking and smoking habits
This study looks at how certain cues (like seeing a drink or a cigarette) trigger cravings and behavior in people who drink alcohol or smoke. Understanding this may help improve addiction treatments.
BerlinAges 16–65 - NCT05993351Recruiting
Concussion assessment using MRI and blood tests
This study uses MRI scans and blood tests to measure brain recovery after a concussion. It will help doctors understand how concussions affect the brain and find better ways to diagnose them.
Hamilton, OntarioAges 9–50 - NCT06031714Recruiting
Fetal cells in women with skin ulcers
This study looks at fetal cells that stay in a woman's body after pregnancy to see if they play a role in chronic skin ulcers. It includes women who have had a baby and have a venous, diabetic, sickle cell, or mixed ulcer, as well as healthy women for comparison.
Paris, Île-de-France RegionAges Any age - NCT06042387Recruiting
Genome study across diverse populations with IBD
This study looks at the genes of people with inflammatory bowel disease (IBD) and healthy volunteers to understand why IBD affects different populations. You may join if you have Crohn's disease, ulcerative colitis, or undetermined IBD, or if you are a healthy person without any IBD history.
Toronto, OntarioAges Any age - NCT06078930Recruiting
Using tongue imaging to screen for stomach cancer
This study uses a special tongue camera to see if the tongue can help doctors find stomach cancer early. It is looking for both people with newly diagnosed stomach cancer and healthy volunteers to compare tongue images.
Hangzhou, ZhejiangAges 18–90 - NCT06123338RecruitingPhase 2
Pembrolizumab plus chemo and trastuzumab for HER2+ stomach cancer
This trial tests adding pembrolizumab to standard trastuzumab and chemotherapy for people with HER2-positive stomach or esophageal cancer that can be fully removed with surgery. The goal is to see if this combination improves outcomes before and after surgery.
Boston, MassachusettsAges 18 years+ - NCT06163625Recruiting
Brain activity and memory in treatment-resistant depression
This study looks at how the brain's frontal lobe (DLPFC) works during memory tasks in people with treatment-resistant depression. It compares brain activity between depressed patients and healthy controls using MRI and possibly a brain stimulation technique (rTMS). It aims to understand why some people don't respond to standard treatments.
Toronto, OntarioAges 18–65 - NCT06186908Recruiting
Saliva test for gum disease diagnosis
This trial studies certain proteins in your saliva to see if they can help identify different types of gum disease. It may help improve how we diagnose and treat periodontal problems.
Izmir, ÇiğliAges 20–60 - NCT06213532Recruiting
Connect to lung care study for smokers
This study, called CONNECTing to LungCare, helps current smokers who get their primary care at UCSF clinics learn about lung cancer screening. The goal is to make it easier for people to get screened and to support smokers in their health journey.
San Francisco, CaliforniaAges 18 years+ - NCT06295263Recruiting
AI for diagnosing and treating brain diseases in older adults
This study uses artificial intelligence to help diagnose and treat brain diseases that affect older adults, such as Parkinson's and Alzheimer's. Researchers will compare AI methods with standard care to see if they can improve diagnosis and treatment.

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