Recruiting studies
- 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.

Testing blood lithium levels in people with depression and suicidality
This study checks how much lithium is naturally present in the blood and whether that relates to suicidal thoughts or attempts in people with a current major depressive episode. It may help researchers understand biological factors linked to suicide risk and improve future prevention.
MontpellierAges 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.

Regorafenib plus aspirin then standard chemo for metastatic bowel cancer
This trial tests whether adding regorafenib and low-dose aspirin before standard chemotherapy can slow metastatic colorectal cancer after it has progressed on prior treatment. It may help by trying a different cancer-fighting approach earlier, followed by the usual chemo plan.
BesançonAges 18 years+ - NCT05531747Recruiting
Study of stress in skin stem cells in hidradenitis
This study looks at how “stress” inside skin cells may be connected to hidradenitis suppurativa, a long-term painful skin condition with recurrent bumps and tunnels. Your participation may help researchers understand what drives the disease.

Trial tests alpelisib for MCAP with PIK3CA mutations
This Phase 2 study tests alpelisib in children and adults with MCAP, a condition caused by a specific PIK3CA gene mutation. The goal is to see if the treatment is effective and safe, while carefully monitoring blood sugar and organ function.
AmiensAges 2–40 - NCT05582915Recruiting
Checking blood tests and scans to predict severe Bell’s palsy
This study looks for early “prognostic biomarkers” (measurable signs in blood/tissue or scans) to predict how severe Bell’s palsy will turn out. It may help doctors better choose the right treatment and follow-up for adults with severe facial nerve weakness.
MontpellierAges 18 years+ - NCT05592574Recruiting
Test of a biologic for active spondyloarthritis
This trial studies whether adding a biologic medicine (targeted therapy) can help people with active spondyloarthritis when standard anti-inflammatory pain medicines (NSAIDs) have not worked well enough. It focuses on people with ongoing symptoms despite trying at least two NSAIDs.
NiceAges 18–90 - NCT05632497Recruiting
Testing gut microbiome changes in adults with anorexia
This study looks at how changing the gut bacteria (microbiome) may affect people hospitalized for anorexia nervosa. You may be eligible if you’re an adult with a very low BMI and meet the study’s timing and health requirements.
VillejuifAges 18 years+ - 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+ - NCT05648136Recruiting
Blood test study for immune markers in miscarriage and IVF failure
This study looks at immune-related blood patterns and other measurements to better understand why some women have repeated pregnancy loss or repeated IVF implantation failure. If you qualify, your answers and test results may help researchers identify biomarkers that could guide future care.
Amiens, PicardieAges 18–39 - NCT05649865Recruiting
Monitor HPV DNA in throat cancer to guide early response
This study checks a substance called HPV DNA in your blood to see how your HPV-positive throat cancer responds early during treatment. It may help doctors spot who is responding well and who may need closer attention sooner.
Lund, Skåne CountyAges 18 years+ - NCT05658172Recruiting
Less vs more frequent follow-up after early breast cancer
This trial compares standard follow-up visits versus more intensive follow-up for people with early breast cancer after their main treatment. The goal is to see whether closer monitoring finds problems earlier or improves outcomes.
UlmAges 18–75 - NCT05659589Recruiting
Using a kidney toxin level to predict heart effects in AKI
This study looks at whether measuring indoxyl sulfate, a substance that can build up when kidneys are injured, can help predict how blood vessels and the heart are affected during acute kidney injury (AKI). It may help doctors understand who is at higher risk of heart-related problems while AKI is happening.
AmiensAges 18 years+ - NCT05675969Recruiting
Testing tiny blood particles in at-risk early delivery
This pilot study looks at tiny particles in blood (microvesicles) to learn how they differ in women with threatened preterm delivery, with or without pre-eclampsia. Results may help doctors better identify risk and improve care for early delivery.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 700 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
