Study of why blood clots in veins come back
This study follows people who have had a vein blood clot (or related venous clot) to understand what factors may make the clot happen again. It may help clinicians find better ways to prevent repeat clots.
BrestAges Any age - NCT04476563Recruiting
Study liver injury from checkpoint cancer immunotherapy
This study looks at why some people develop liver inflammation after checkpoint inhibitor cancer treatment, called checkpoint inhibitor–induced liver injury (ChILI). It compares people with ChILI to similar cancer patients who are starting the same type of immunotherapy, to better understand and track these liver injury events.
NottinghamAges 18 years+ - NCT04837339Recruiting
Testing markers to predict problems after lung transplant
This study looks for lab “clues” that can help predict how well someone’s lungs will do after a lung transplant. It may help doctors spot transplant-related problems earlier so care can be planned sooner.
SuresnesAges 15 years+ - NCT03541525Recruiting
Study on red blood cell-related diseases in families
This study looks at how red blood cells work in people who have a related condition—or who have family members with one. It may help researchers understand causes of these diseases and improve future care.
CotonouAges Any age - NCT06678022Recruiting
Using medical drones to deliver HIV treatment in Kalangala
This study tests whether medical drones can safely deliver HIV medications and lab samples in remote areas. If successful, it could help people living with HIV get their medicine faster and more reliably.
Kalangala, SseseAges 15 years+ - NCT06372054Recruiting
Predicting health risks for Italian Air Force members
This study aims to develop smart risk models using your body's data (like proteins and genes) along with personal exposure readings. It will help predict health risks for Italian Air Force personnel. You will wear a monitor and give samples, then be followed over time.
MilanAges 26–38 - NCT07119086Recruiting
Arbovirus infection study in the Indian Ocean
This study looks at patients with suspected, probable, or confirmed arbovirus infections (like dengue, chikungunya, or Zika) to understand what factors lead to hospitalization and how severe the illness can be. It may include adults, children, and even newborns if they might have been exposed.
Saint-PierreAges Any age - NCT07417072Recruiting
Brain tumor drug testing using 3D models in children
This study creates 3D models from brain tumor tissue of children aged 3-18 to test how different drugs might work against their specific tumor. The goal is to find more personalized treatments.
Florence, FirenzeAges 3–18 - NCT06310239Recruiting
Microbiome Study for Adults Having Surgery
This study looks at how your body’s natural bacteria (called the microbiome) may change after surgery. Researchers want to learn about the gut and skin bacteria of adults who are having a procedure, which could help improve recovery in the future.
Bethesda, MarylandAges 18–75 - NCT06702891Recruiting
Exosome study of gastric cardia cancer
This study looks at tiny particles called exosomes from your cancer cells to better understand gastric cardia cancer. It may help doctors find new ways to diagnose or treat this type of stomach cancer.
Jinan, ShandongAges 18 years+ - NCT05947864Recruiting
Measles immunity monitoring after bone marrow transplant
This study checks how well adults stay protected against measles after they receive a donor bone marrow transplant. It helps doctors understand measles immune status and may guide future protection for transplant recipients.
LyonAges 18–75 - NCT06600295Recruiting
Taste changes and nutrition in new cancer patients
This study looks at how cancer and its treatments affect taste and nutrition. It aims to find ways to help patients maintain good nutrition during treatment.
DijonAges 18 years+ - NCT06242509Recruiting
Akkermansia bacteria in prostate cancer
This trial looks at whether a specific gut bacterium, Akkermansia muciniphila, is linked to how well hormone therapy works in men with advanced prostate cancer that no longer responds to standard hormone treatment. You may join if you are about to start a new type of hormone therapy.
ParisAges 18–100 - NCT07259226RecruitingPhase 2
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+ - NCT03408964Recruiting
Blood tests to predict treatment response in prostate cancer
This study checks whether certain blood markers can help predict how well people with prostate cancer will respond to therapy. It may help doctors choose the most effective treatment sooner by using information from your blood.
BellinzonaAges 18 years+ - NCT03559569Recruiting
Study blood changes in people with circulatory shock
This study looks at how blood vessel and white blood cell aging changes during circulatory shock. Your participation may help doctors better understand what’s happening in the body during shock.

Common questions
- Are there clinical trials studying Biological sampling?
- Yes. Clin2 currently lists 149 recruiting studies that include Biological sampling, 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 sampling 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 sampling 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 sampling or a specific trial is right for you.
