Studying resistance to antibody-drug conjugates in advanced cancer
This study is for people with advanced breast, bladder, lung, or stomach cancer who are about to start treatment with a type of targeted therapy called an antibody-drug conjugate (ADC). The trial will collect tumor samples and blood to understand how cancers become resistant to these drugs and to find better ways to predict treatment success.
VillejuifAges 18 years+ - NCT04024774Recruiting
Genetic testing study for rare diseases with an unclear cause
This study looks for a genetic (DNA) explanation for rare diseases when usual genetic testing hasn’t found an answer. It may help by re-analyzing prior results and comparing them with parents’ DNA to better pinpoint the cause.
DijonAges Any age - NCT02614911Recruiting
Genetics and health profile study for early severe bowel disease
This study looks at how an early-onset bowel illness looks and what genetic changes may be involved. It may help researchers better understand inherited causes and improve future care for families affected by these conditions.
BordeauxAges Any age - NCT07131605Recruiting
How weight-loss surgery affects heart health and inflammation
This study looks at how weight-loss surgery affects heart health by checking markers of inflammation in the blood and how blood vessels work. It may help understand why surgery lowers heart risk for people with obesity.

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.

Common questions
- Are there clinical trials studying Biological samples?
- Yes. Clin2 currently lists 146 recruiting studies that include Biological samples, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Biological samples trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Biological samples an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Biological samples or a specific trial is right for you.
