Blood markers for poor outcomes after sepsis in cancer surgery
This study looks at blood markers (epigenetics) to better understand why some people have a harder time recovering from a severe infection after major cancer surgery. The goal is to find early signs of poor outcomes in men aged 45–75 with post-surgery sepsis.

Why amivantamab stops working in certain lung cancers
This study looks at how and why lung cancers with a specific EGFR mutation (exon 20 insertion) become resistant to the drug amivantamab. It collects blood and tumor samples from patients whose cancer has progressed on amivantamab to better understand resistance.
BordeauxAges 18 years+ - NCT06150898RecruitingPhase 2
Ketorolac and pregabalin for estrogen receptor positive breast cancer before surgery
This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
Brussels, Brussels CapitalAges 18–70 - NCT06097156Recruiting
Automated blood test for breast cancer monitoring
This trial tests an automated device that prepares blood samples to detect cancer-related changes. It aims to improve how doctors monitor breast cancer that has spread, without needing a tissue biopsy every time.
MilanAges 18 years+ - NCT05267041Recruiting
Lung cancer database study at Lyon hospitals
This study collects information about people who have been treated for lung or chest cancers at Lyon University Hospital. Your data may help researchers better understand these cancers and improve future care.
Pierre-BéniteAges 18 years+ - NCT05858398Recruiting
How body composition affects chemotherapy results in breast cancer
This study looks at whether body fat and muscle (body composition) change how well certain chemotherapy works after surgery for early breast cancer. You may be considered if you are planned to receive docetaxel as adjuvant (after-surgery) chemotherapy and have recent CT scan images.
RouenAges 18 years+ - NCT05714592Recruiting
Optical genome mapping for bone marrow changes in blood cancer
This trial tests whether a special eye-based lab test called optical genome mapping can better detect new (acquired) chromosome changes in people with certain slow-growing blood cancers. It may help doctors choose the right next steps based on what’s happening in the bone marrow.
Amiens, PicardieAges 18 years+ - NCT03420118Recruiting
Study of tumor and blood markers in gynecologic cancers
This study looks at tumor tissue and blood samples to find biological “markers” in people with gynecologic cancers. It may help researchers understand disease better and could guide future, more personalized treatments.
Toronto, OntarioAges 18 years+ - NCT05400590Recruiting
Test blood-based eye drops to help cornea healing
This study compares two types of blood-derived treatments (a growth-factor enriched plasma product versus your own serum) to see which helps corneal cells heal better in people with aniridia. It may be helpful if you need improved cornea healing, but you must meet blood-safety and eye-sample requirements.
ParisAges 18 years+ - NCT05443087Recruiting
Checking blood levels of targeted drugs for digestive cancers
This trial monitors how your prescribed targeted cancer medicine moves through your body by doing extra blood tests. The goal is to understand the drug’s levels and dosing in people with advanced digestive cancers, so treatment can be better managed.
AmiensAges 18 years+ - NCT04530890Recruiting
Testing blood tumor DNA in digestive and breast cancers
This study looks at a blood test for “circulating tumor DNA” (tiny pieces of cancer-related DNA in the blood). It may help doctors learn more about digestive, gynecologic, or breast cancers and how patients respond when treatment like chemotherapy or immunotherapy is needed.
PoitiersAges 18 years+ - NCT04873492Recruiting
Study how genes and blood signals relate to MS outcomes
This study looks at genetic information and blood test signals to understand why some people with early MS develop a worse outcome. It may help doctors predict who is at higher risk and better understand disease mechanisms.
Nantes, Loire-AtlantiqueAges 18 years+ - NCT04798651Recruiting
Study immune blood and spinal fluid cells in multiple sclerosis
This study looks at different immune cells in blood and, sometimes, spinal fluid (CSF) to understand what’s driving multiple sclerosis (MS) or early MS-like symptoms. Your participation may help researchers better explain the disease and potentially improve how it’s diagnosed or treated.
BordeauxAges 18 years+ - NCT04154332Recruiting
Study of pregnancy-related cell signals in preeclampsia
This study collects samples from pregnant people with preeclampsia (a serious pregnancy blood-pressure condition) and from healthy pregnancy controls. Researchers will study tiny particles (“exosomes”) to see how they differ and whether these signals could help explain or improve care for preeclampsia.
Birmingham, AlabamaAges 18–45 - NCT03610802Recruiting
Send blood samples to study genetic and immune differences
This study collects blood (and sometimes related samples) to learn how genes and the immune system work in people with primary immunodeficiency (PID) or in family members who may not have it. The goal is to improve understanding of rare immune conditions and help guide future care.
Bethesda, MarylandAges 1 day–99 years - NCT03538600Recruiting
Sample collection from healthy volunteers to improve test accuracy
This study collects multiple types of samples (like blood, stool, saliva, and swabs) from healthy people. The goal is to optimize lab tests for future research, which may help doctors and scientists run more accurate immune-related measurements.
Bethesda, MarylandAges 3–80 - NCT03612310Recruiting
Study uses stem cells to model genetic diseases
This study looks at how to create laboratory models of genetic diseases using stem cells made from people’s cells. It may help researchers understand disease causes and how treatments could work, using genetic patients (and some non-patient controls).
Edinburgh, MidlothianAges 1–120 - NCT03025074Recruiting
Blood sample bank for liver disease research
This study collects blood samples to build a “biobank” (a stored library of samples) for researchers studying liver diseases like hepatitis, fatty liver disease, and liver cancer. It may help future testing and treatments by allowing scientists to study patterns in people with and without liver conditions.
Buffalo, New YorkAges 7 years+ - NCT02280161Recruiting

- Yes. Clin2 currently lists 269 recruiting studies that include Blood sample 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 sample 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 sample 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 sample collection or a specific trial is right for you.
