Recruiting studies
- NCT05505669Recruiting
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.

Timing of dental implant placement and early healing
This trial compares placing a dental implant right after a tooth is pulled versus waiting for the socket to heal first. It aims to see which timing leads to better healing at the molecular level.

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.

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.

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+ - NCT06101303Recruiting

This study looks at pain in people with or without endometriosis who are having laparoscopic surgery. Researchers want to understand more about pelvic pain by collecting information before, during, and after surgery.
St Louis, MissouriAges 12–45 - 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 - 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 - 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 - NCT06037421Recruiting
Bacteria in breast milk of NICU mothers
This study looks at the bacteria naturally found in breast milk. Researchers want to learn more about the germs in milk from mothers whose babies are in the neonatal intensive care unit.
Corbeil-Essonnes, FranceAges 1 hour+ - NCT06021548Recruiting
Opioid addiction markers study
This study looks at physical, psychological, and social factors that may be linked to opioid addiction. It aims to better understand addiction to help improve future treatments.
BronAges 18 years+ - 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 - NCT05938166Recruiting
Training foreign caregivers with an augmented reality system
This study tests whether an augmented reality (AR) training system can help foreign care workers learn how to provide care. It involves Indonesian caregivers training for caring for older adults in Kaohsiung, with tests based on the older adult’s ability to follow instructions.
Kaohsiung City, Sanmin DistAges 21–65 - NCT05937594Recruiting
Testing microRNA markers to spot newborn opioid withdrawal
This study looks at tiny genetic signals (microRNA) in newborn samples to identify neonatal opioid withdrawal syndrome. It may help doctors recognize withdrawal sooner, so babies can get the right care faster.
Hershey, PennsylvaniaAges 1 day–5 days - NCT05895890Recruiting
Studying alcohol-related liver disease and addiction care
This study follows adults with alcohol-related liver disease to better understand and manage alcohol addiction and related health problems. You may be able to help researchers by sharing health information and consented care experiences.
Clamart, Île-de-France RegionAges 18–75 - NCT05858502Recruiting
Study immune response to COVID-19 and improve testing
This study looks at how the immune system in the body responds to different COVID-19 virus variants. It may help improve how COVID-19 is diagnosed by comparing people who are currently infected and those who are not.
ParisAges 18–65 - NCT05724992Recruiting
Study genetic testing in families at pancreatic cancer risk
This program invites people whose families are followed in a pancreatic cancer registry to do a saliva swab genetic test. It helps researchers learn how to identify genetic risk in families and may guide future care.
VeronaAges 18–80 - NCT05588154Recruiting
Donate blood and other samples to study blood cancers
This study asks healthy adults to provide blood, bone marrow (if needed), skin, saliva, and stool samples. Scientists use these samples to compare patterns related to myeloid (bone-marrow) blood cancers, which may help future research and tests.
Bethesda, MarylandAges 18–120 - NCT05444127Recruiting
Study of oral health in people with Wilson’s disease
This study compares oral (mouth and teeth) health in people with Wilson’s disease versus people without it. It aims to see whether Wilson’s disease is linked to specific dental and imaging findings, which could help with future prevention and care.
Ivry-sur-SeineAges 18 years+ - 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 - NCT04860453Recruiting
Family genetic testing study for patterns of different cancers
This study checks whether gene tests can help understand cancer risk in families where different relatives had different (discordant) cancers. It may help families and doctors better understand whether hereditary cancer risk is possible, even though some parts use routine standard care as a comparison group.
Cleveland, OhioAges 18–100 - NCT04442516Recruiting
Testing kidney injury risk from cisplatin cancer treatment
This study looks at how cisplatin chemotherapy affects the kidneys. It may help doctors better predict and protect against kidney damage when patients start cisplatin.
London, OntarioAges 3 months+ - NCT04085900Recruiting
Screening test for nasopharyngeal cancer blood markers
This study screens people in certain cities to see whether signs in the blood related to a virus (EBV) can help find nasopharyngeal cancer earlier. It may help identify higher-risk people so they can be checked sooner.
Zhongshan, GuangdongAges 30–69 - NCT03386981Recruiting
Study of bone health patterns in healthy adult athletes
This study looks at what bone “profiles” look like in healthy adult athletes. It may help researchers better understand how normal bone health varies in people who are physically active.

Common questions
- Are there clinical trials for saliva?
- Yes. Clin2 currently lists 82 recruiting saliva studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- 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.
