- NCT07218601RecruitingPhase 2
Using breath testing to track lung cancer treatment
This trial uses a special breath test (E-Nose) to monitor how well treatment is working in people with non-small cell lung cancer. You just breathe into a device, and it measures compounds in your breath.
Basking Ridge, New JerseyAges 18 years+ - NCT04165798Recruiting
Pembrolizumab with or without chemotherapy for stage IV lung cancer
This trial tests whether pembrolizumab alone, or pembrolizumab plus chemotherapy, can treat stage IV non-small cell lung cancer. It may help shrink tumors and improve outcomes by boosting the immune system, with or without added chemotherapy.
Gilbert, ArizonaAges 18 years+ - NCT05852925Recruiting
Self-collecting blood at home to help diagnose health conditions
This study checks whether people can collect their own blood sample using the Tasso+ kit and still get reliable test results. It may help make future diagnostic testing easier by supporting at-home or self-collection of samples.
Atlantis, FloridaAges 13 years+ - NCT04599621Recruiting
Testing treatment for heart pain with anxiety or depression
This trial looks at people who have coronary artery disease and unstable or certain stable chest-pain symptoms, especially when anxiety or depressive symptoms are also present. The goal is to see how the study approach helps heart symptoms when mental health symptoms occur at the same time.
SamarkandAges Any age - NCT07001085Recruiting
Blood test to monitor liver cancer after surgery
This study uses a simple blood test to monitor tiny pieces of tumor DNA (ctDNA) in people with colorectal cancer that spread to the liver or with liver cancer (HCC), before and after liver surgery or transplant. It aims to help doctors detect cancer return earlier and guide treatment.
Warsaw, Masovian VoivodeshipAges 18–75 - NCT05975593Recruiting
Study how radiation affects tumor biology in cervical or pancreatic cancer
This study looks at how radiotherapy changes the tumor environment, using lab samples collected during treatment. It may help researchers understand why radiation works differently for different people and could improve future treatment planning.
St Louis, MissouriAges 18 years+ - NCT07275489Recruiting
Long-term isolation and your immune system
This study looks at how long-term isolation on remote islands affects your immune system. If you are a healthy adult who will spend a year living on the Kerguelen Islands, this trial will track your health over time.
Port-aux-Français, Terres Australes Et Antarctiques FrançaisesAges 18 years+ - NCT05994976Recruiting
Collecting skin samples from people with skin conditions
This study collects skin samples (like small biopsies or swabs) from people with certain skin conditions and from healthy volunteers. The samples help researchers learn more about these conditions and may lead to better treatments.
Montreal, QuebecAges 18 years+ - NCT04838171Recruiting
Study of White Blood Cells in Donors and Patients
This study looks at white blood cells (the body’s immune cells) to learn more about how they behave in health and/or illness. Participation may help researchers understand immune-related changes and support future treatments.
LondonAges Any age - NCT07265544Recruiting
Liver disease study using advanced tissue analysis
This study uses advanced techniques to analyze liver tissue samples from people with various liver conditions. It aims to better understand how liver diseases develop and progress, which may help improve future treatments.
Guangzhou, GuangdongAges Any age - NCT06151223Recruiting
Pancreatic cancer risk registry for high-risk individuals
This study is a registry for people at high risk for pancreatic cancer. Researchers will collect information over time to learn more about how to detect and prevent the disease.
Rochester, MinnesotaAges 18 years+ - NCT07008092Recruiting
Using PGE-M to predict appendicitis in children
This trial checks if a substance called PGE-M found in urine can help predict acute appendicitis in children with belly pain. If it works, it could help doctors diagnose appendicitis faster and without needing a blood test or CT scan.
SplitAges 5–17 - NCT05564026Recruiting
Study of DNA patterns in childhood germ cell tumors
This study looks at “molecular” (DNA-related) features of germ cell tumors in children and teens. It also follows patients over time, which can help researchers understand tumor patterns and improve future care.
Minneapolis, MinnesotaAges Any age - 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 - NCT04883502Recruiting
Testing a technique to rebuild bone lost after injury
This study looks at a surgical method that creates an “induced membrane” to help rebuild bone after traumatic injury. It may help people whose limb bones were damaged and are missing part of the bone.
ClamartAges 18 years+ - NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - NCT06842316Recruiting
Study on cannabis-like compounds for inflammatory arthritis
This trial tests whether plant-based compounds similar to cannabis (called phytocannabinoids) can help calm inflammation and improve immune function in people with certain types of arthritis or autoimmune diseases like lupus or Sjögren's disease. It aims to offer a new way to treat these conditions without the 'high' of marijuana.
OrléansAges 18 years+ - NCT06355713Recruiting
Symptom improvement after Essure implant removal
This study looks at women who are having symptoms from their Essure contraceptive implant and want it removed. It will measure how their symptoms improve after removal and may also include a special brain scan (MRI-PET) to check for changes.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 338 recruiting studies that include Blood collection, 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 Blood collection 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 Blood collection 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 Blood collection or a specific trial is right for you.
