This study looks at pregnant women with parvovirus B19 infection and follows what happens with the baby, including any health issues after birth. It helps doctors understand how the infection affects pregnancy.
Pavia, LombardyAges 18 years+ - NCT06986265Recruiting
Kidney failure, weight loss, and gut health study
This study looks at how gut bacteria might affect weight loss in people with kidney failure who are on dialysis. It may help find new ways to prevent or treat weight loss in this condition.
BrusselsAges 18 years+ - NCT07063680RecruitingPhase 3
Testing early argipressin for shock not helped by norepinephrine
This trial tests a medicine called argipressin for people in the ICU with vasoplegic shock (very low blood pressure due to widened blood vessels) that isn't improving with high doses of the usual medicine, norepinephrine. The goal is to see if adding argipressin early helps raise blood pressure and improves outcomes.
DijonAges 18 years+ - NCT05542056Recruiting
Test urine markers to predict low sodium from water pills
This study looks for a signal in your urine that could help predict who will develop low blood sodium (hyponatremia) after starting a thiazide-type “water pill.” It may help doctors spot higher-risk people early and adjust care sooner.
MóstolesAges 18 years+ - NCT06736288RecruitingPhase 4
Buccalin® tablets to prevent repeat lung infections
This trial tests whether Buccalin® tablets can help adults who get frequent lower respiratory infections (like bronchitis or COPD flare-ups). It's a phase 4 study collecting more data on safety and how well the medicine works to prevent these infections from coming back.
AlessandriaAges 18–99 - NCT05652101Recruiting
Study of skills and development in hyperekplexia
This study looks at how children and adults with hyperekplexia develop and adapt over time. It may help researchers understand what support or treatment approaches work best for day-to-day development.
BronAges 2 years+ - NCT06606119Recruiting
Brain, bone marrow, and gut study after major injury
This study is looking at how the brain, bone marrow, and gut interact after a severe injury. It may help doctors understand how to better treat trauma patients.
Gainesville, FloridaAges 18–100 - NCT06614101Recruiting
Breath test for monitoring blood sugar
This study is testing a new device that measures blood sugar levels by analyzing your breath. It is for people with type 2 diabetes or those who are overweight, to see if the breath test can work as a non-invasive way to monitor glucose.
Salies-du-Salat, FranceAges 18 years+ - NCT06478121Recruiting
Understanding how genes affect beta cells
This study looks at how specific genetic changes affect beta cells, which make insulin. It may help people with rare genetic forms of diabetes or other beta cell disorders, and also needs healthy volunteers for comparison.
Exeter, DevonAges 6–99 - NCT00267501Recruiting
Study collects data and samples to understand eosinophilic conditions
This study collects information and biological samples to better understand what causes certain allergic/eosinophilic conditions. It may help researchers learn mechanisms and improve future care.
Cincinnati, OhioAges Any age - NCT06300697Recruiting
Food allergy and eczema study at University of Michigan
This study looks at how food allergies and eczema (atopic dermatitis) are related. You will have an oral food challenge (eating a small amount of a possible allergen in a safe setting) and give blood and skin samples to help researchers learn more.
Ann Arbor, MichiganAges 10–55 - NCT06150898RecruitingPhase 2
Ketorolac and pregabalin for estrogen receptor positive breast cancer before surgery
This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
Brussels, Brussels CapitalAges 18–70 - NCT05265429Recruiting
Study of young people’s lung cancer biology
This study looks at biological samples from people diagnosed with lung cancer at age 45 or younger. It may help researchers understand how young lung cancers differ, which could guide future treatments.
Boston, MassachusettsAges 15 years+ - NCT05383963Recruiting
Using ICU routine data to diagnose sepsis sooner
This study checks whether information collected routinely in the ICU can help doctors recognize sepsis or septic shock earlier. If it works, it may improve how quickly diagnosis happens and potentially outcomes for patients.

NIDCD medical data and sample collection for communication disorders
This study collects medical information and specimens to support research on problems with hearing, balance, taste, smell, voice, speech, and language. It may help you (or your child) get additional evaluation and follow-up through NIDCD, especially if your clinician thinks it could be useful.
Bethesda, MarylandAges 2–99 - NCT05587439Recruiting
Study of inherited genetic risk in lung and related cancers
This study looks for inherited (family-passed) genetic changes that may raise the risk of lung cancer and related thoracic cancers. It may help people and families understand their genetic risk by collecting health information and sometimes specimens from patients and relatives.

Common questions
- Are there clinical trials for data collection?
- Yes. Clin2 currently lists 328 recruiting data collection 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 data collection 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 data collection 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.
