How radiotherapy changes a tumor’s immune response
This study looks at how a tumor’s immune system responds when you receive radiotherapy. It involves taking a planned pre-treatment biopsy so researchers can study immune and tumor changes and see if radiotherapy affects them.
ManchesterAges 18 years+ - NCT05078957Recruiting
Study gut microbiome in older adults with well-controlled HIV
This trial studies how the bacteria in your gut (“microbiome”) relate to frailty (weakness/low physical resilience) in people with HIV who are stably doing well on treatment. It may help researchers understand why some people become frail and how the gut may play a role.
MarseilleAges 55 years+ - NCT05082961Recruiting
Blood immune markers and brain radiation after head/neck surgery
This study looks at immune system signals in your blood during and after postoperative radiation therapy for certain head and neck cancers involving the brain or skull base. Researchers want to see whether these “immune markers” relate to treatment response or side effects.
CaenAges 18 years+ - NCT05303337Recruiting
Study of gut and HIV changes after switching to long-acting shots
This trial compares how HIV “reservoirs,” inflammation, and the gut microbiome change when people switch from daily HIV pills to long-acting injectable treatment. It may help you and your team understand what to expect with the switch and how your body responds.
MarseilleAges 18 years+ - NCT05588154Recruiting
Donate blood and other samples to study blood cancers
This study asks healthy adults to provide blood, bone marrow (if needed), skin, saliva, and stool samples. Scientists use these samples to compare patterns related to myeloid (bone-marrow) blood cancers, which may help future research and tests.
Bethesda, MarylandAges 18–120 - NCT05639413Recruiting
Study of biology in people with BRAF V600E metastatic colon cancer
This study follows people with BRAF V600E–positive metastatic colorectal (colon) cancer to better understand how the cancer’s biology changes over time. It may help researchers learn which features to watch and how this cancer behaves after initial treatment.
AvignonAges 18 years+ - NCT05672615Recruiting
Mood changes during bladder cancer treatment with BCG
This study looks at how bladder cancer treatment with BCG may affect mood and emotional well-being. It may help doctors understand which patients experience mood changes during care.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05750147Recruiting
Study for cardiomyopathy linked to family or genes
This study looks at people with cardiomyopathy (or related heart muscle conditions) and those who may be at risk because of family history or genetic test results. It may help researchers better understand who is likely to develop the condition and how best to monitor or support them.
LondonAges Any age - NCT05793008Recruiting
Studying heart stress syndrome in sepsis using heart scans
This study looks at Takotsubo (also called stress cardiomyopathy) and heart problems caused by sepsis using specialized heart imaging (including PET). The goal is to better understand what triggers these conditions and how the heart is affected, which may improve diagnosis and care.
RomeAges 18 years+ - NCT06046651Recruiting
Blood sample collection for lab research
This study collects blood samples from healthy adults to help researchers learn more about how to run lab tests. It involves one visit or at-home collection and might help future medical research.
San Francisco, CaliforniaAges 18 years+ - NCT06123962Recruiting
Identifying lung injury subtypes to guide treatment
This study looks at different patterns in patients with a severe lung condition called ARDS, to better understand why some respond to treatments differently. You may help doctors learn how to personalize care.
BeijingAges 18 years+ - NCT06434207Recruiting
Heart defect study in newborns to understand blood clots

Study of biomarkers in lichen planus
This study looks at people with lichen planus (a rash that can affect skin, mouth, or genitals) to find markers in cells and blood that may help understand the disease. If you have a new diagnosis or a flare-up, and you are not on strong immune-suppressing medicine, you may be able to join.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 347 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.
