Blood and tissue collection study for certain lung cancers
This study collects blood and tissue samples from people with non-small cell lung cancer (NSCLC) either before or after treatment. It aims to help researchers learn more about how tumors respond, especially in cancers with specific genetic changes or after certain pre-surgery therapies.
London, United KingdomAges 18 years+ - NCT07085611Recruiting

This study looks at how tryptophan (a natural amino acid) affects how well triptans work for migraines. You may be able to join if you've taken triptans before, whether they helped or not.
Clermont-FerrandAges 18–50 - NCT07384897Recruiting
Immune cells in lung cancer and chronic lung disease
This study looks at how immune cells work in lung cancer and chronic lung diseases. It aims to find better ways to treat these conditions by studying immune cells from blood, bone marrow, or lung samples.
BrusselsAges Up to 80 years - NCT02735824Recruiting
Genetic study of immune problems in children
This study looks for new genetic causes of immune system conditions that can run in families. If you join, researchers will collect health information (and usually samples) from children with immune concerns and from close relatives for comparison.
Zurich, Canton of ZurichAges Any age - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
Philadelphia, PennsylvaniaAges 18 years+ - NCT01205815Recruiting
Use and storage of leftover melanoma tissue for future testing
This study collects and stores leftover melanoma tissue (and sometimes blood) for future research and testing. If the trial uses your stored samples to help match treatments, it could support better care planning over time.
Nashville, TennesseeAges 18 years+ - NCT01173341Enrolling by invitation
Checking heart side effects of breast cancer treatments
This study looks at how breast cancer medicines affect the heart. It may help doctors better prevent, spot early, and manage heart side effects from trastuzumab and/or anthracycline chemotherapy.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07452432Recruiting
Study of chemo before surgery for aggressive kidney/ureter cancer
This study tests whether giving chemotherapy before surgery can help patients with high-grade upper tract cancer that hasn't spread. It aims to find better ways to treat this aggressive cancer.
SeoulAges 19 years+ - NCT06508138Enrolling by invitationPhase 1
HPV vaccine study for healthy relatives of patients
This trial tests two experimental vaccines to boost the immune system against HPV 16. Healthy relatives of patients with HPV 16 cancer receive the vaccines, then donate blood cells for research.
Baltimore, MarylandAges 18–70 - NCT04112355Enrolling by invitation
Tracking children’s immune response after routine vaccinations
This study measures how a child’s immune system responds after standard childhood vaccines, like DTaP-IPV/Hib, pneumococcal, MMR, varicella, flu, and COVID shots. It may help researchers better understand what a “healthy” immune response looks like after vaccination.
Rochester, MinnesotaAges 4 months–21 years - NCT04970472Recruiting
Urothelial bladder cancer sample collection for adults
This trial collects clinical samples from adults who have suspected or confirmed urothelial (bladder/urinary tract lining) cancer. It helps researchers study the disease and may support future improvements in diagnosis or treatment.
ToulouseAges 18–99 - NCT05014165Recruiting
Cord blood study for leukemia with stored birth samples
This study looks at leukemia “genetic clues” using special stored samples, including cord blood saved at birth. It may help researchers better understand leukemia biology and how common mutations may show up early.
Minneapolis, MinnesotaAges Up to 25 years - NCT06661564Recruiting
Testing tears for Alzheimer's disease diagnosis
This study looks at whether tears can help detect Alzheimer's disease. You will have your tears collected and tested for possible biomarkers.
Tours, FranceAges 18 years+ - NCT02168868Recruiting
Blood tests to find autism-related protein signals
This study looks at blood samples from children (and sometimes parents) to see if certain protein patterns can help identify or better understand autism spectrum disorder. The results could support finding “biomarkers,” which are measurable signs that may guide future research or care.
JerusalemAges 10 months–19 years - NCT07054346RecruitingPhase 1
Comparing two radiation drugs for high-risk prostate cancer before surgery
This trial tests two radioactive drugs (Lu-177 and Ac-225 PSMA-617) given before prostate removal surgery in men with high-risk prostate cancer that hasn't spread far. The goal is to see which drug works better at targeting cancer cells.

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.
