Studies side effects after cancer immunotherapy
This study collects information and biological samples from people who have had significant side effects after immunotherapy for cancer. It aims to understand why these side effects happen and how to improve care for patients in the future.
Anchorage, AlaskaAges Any age - NCT02714387Recruiting
Study of serious complications from non-traumatic blood vessel brain problems
This study follows people who have non-injury (non-traumatic) blood-vessel-related problems in the brain to understand serious complications. It may help researchers identify risks and improve care over time.
AngersAges 15 years+ - NCT07413029Recruiting
A study on people with PRSS1 gene changes
This study follows people who have a specific change (mutation) in the PRSS1 gene. The goal is to learn more about how this gene change affects health over time, which could help with future care.

Study of families with TP53 gene changes in Li-Fraumeni syndrome
This study is looking at how people in families with certain TP53 gene changes (including Li-Fraumeni syndrome) develop health problems over time. It may help doctors better understand risk and improve care for affected families.
Boston, MassachusettsAges Any age - NCT05265429Recruiting
Study of young people’s lung cancer biology

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.
BerlinAges 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.

Common questions
- Are there clinical trials for data collection?
- Yes. Clin2 currently lists 338 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.
