Recruiting studies
- NCT05181748RecruitingPhase 2/Phase 3
Platelet-rich plasma into ovaries for low egg response
This trial tests whether injecting your own platelet-rich plasma (PRP) into the ovaries can improve egg production in people who don’t respond well to fertility stimulation. It may help some “poor responders” get more usable eggs for IVF.
Athens, AtticaAges 35–47 - NCT05039463Recruiting
Platelet-Rich Plasma and Hyaluronic Acid for Knee Arthritis
This trial tests whether combining two types of injections—platelet-rich plasma (a concentration of healing cells from your own blood) and hyaluronic acid (a natural lubricant)—can reduce knee osteoarthritis pain and improve function over one year. You're eligible if you've already received or are about to receive these injections at Amiens University Hospital.
AmiensAges 18 years+ - NCT05038722Enrolling by invitation
Testing how platelet transfusions work in people with low platelets
This study looks at platelet transfusions—how they’re used and whether platelets function well—for people with blood cancers who have low platelet counts. It may help improve transfusion care for people who need platelet support.
LinköpingAges 18 years+ - NCT04031456RecruitingPhase 2/Phase 3
PRP treatment to help ovaries work again in early ovarian failure
This trial studies whether an injection of your own PRP (platelet-rich plasma) can improve how your ovaries work in people with early ovarian failure. If it helps, it may lead to better hormone balance and return of more regular ovulation and periods.
AthensAges 25–39 - NCT02762162Recruiting
Registry of heart artery patients’ platelet test results
This registry collects information from people with coronary (heart) artery disease who already had platelet-related blood tests as part of usual care. The goal is to better understand how platelet responses relate to treatment and outcomes, which may help future care.
ParisAges 18 years+ - NCT04716803Recruiting
BMAC injection for severe knee osteoarthritis before knee surgery
This trial studies injecting “bone marrow aspirate concentrate” (BMAC) into the knee to help relieve pain from severe knee osteoarthritis. It’s for people who have strong signs of advanced arthritis on X-ray and still have ongoing pain despite usual treatments, before a planned knee procedure.
La Jolla, CaliforniaAges 45–75 - NCT05985447Recruiting
Menopause and blood cell function study
This study looks at how menopause affects blood cells and platelets in people with heart or lung conditions. It may help understand why risks change after menopause.
DüsseldorfAges 18 years+ - NCT06026436Recruiting
Predicting clot and bleeding risk in kidney disease patients after a heart attack
This trial tests whether a blood test looking at platelets and tiny cell particles can help predict future blood clots or bleeding in people who have both chronic kidney disease and a recent heart attack. The goal is to improve treatment safety.
MarseilleAges 18–90 - NCT04330729Recruiting
Aspirin effect on blood clotting in kidney disease
This study checks how aspirin (also called salicylate) affects how platelets work, which helps blood clot. It involves people with advanced chronic kidney disease who are treated with Aranesp, and it may help guide safer care.
RoskildeAges 18–85 - NCT06261658Recruiting
Using your own blood to improve ovary tissue transplant
This study tests whether using a special mix made from your own blood (called platelet-rich plasma) can improve the success of putting frozen ovarian tissue back into your body. This might help restore your fertility and hormone function after cancer treatment or other conditions.
Bologna, BOAges Any age - NCT05714241Recruiting
Blood tests to study heart pain with blocked-unblocked arteries
This study looks at blood “biomarkers” and platelet function to better understand INOCA (heart-related chest pain despite no major artery blockage). You may be eligible if you have INOCA and are already taking aspirin, and if you haven’t taken certain blood-thinner or platelet-altering medicines recently.
RomeAges 18 years+ - NCT03491761RecruitingPhase 2
PRP injection versus hyaluronic acid shots for knee arthritis
This trial tests whether a platelet-rich plasma (PRP) shot works better than a standard hyaluronic acid (“gel”) injection to reduce knee osteoarthritis pain. It may help people with ongoing knee pain choose the treatment that relieves symptoms more effectively.
Skokie, IllinoisAges 18–75 - NCT06347640Recruiting
Blood clot treatment for dead permanent teeth
This trial is testing a new way to save a dead tooth by using a special blood clot (platelet-rich fibrin) to help the tooth heal itself. It is for adults who have a permanent tooth that is dead and infected at the root tip, but still has a good chance of being saved.
IrbidAges 12–60 - NCT06442319Recruiting
PRP after ACL reconstruction
This trial tests if injecting platelet-rich plasma (a concentration of your own blood platelets) after ACL reconstruction helps with healing and reduces pain. It's for people who recently had ACL surgery and want to try an extra treatment to improve recovery.
TorunAges 18–45 - NCT07836231Recruiting
Comparing two procedures for deep gum pockets
This study compares two surgical methods to treat deep gum disease pockets around teeth. Both methods aim to help the bone and gum heal better after treatment.
Giza, Giza GovernorateAges 18 years+ - NCT06478537RecruitingPhase 2
Hetrombopag for Immune Tolerance in ITP After Platelet Recovery
This study tests whether a drug called hetrombopag can help your immune system stop attacking your platelets, so your platelet count stays up even after stopping the drug. It's for people with ITP who responded well to hetrombopag but want to see if they can stay in remission without it.
Beijing, Beijing MunicipalityAges 18–50 - NCT07818447Recruiting
Different ways to preserve bone after tooth removal
This study compares different ways to preserve the bone where a tooth is removed, which may help keep the area ready for future implants or other dental work. If you're having a tooth pulled due to gum disease, this trial could help maintain your jawbone and support better healing.
Thessaloniki, ThessalonikiAges 18 years+ - NCT07813377Recruiting
Blood clotting test to predict outcomes after brain tumor surgery
This study looks at a special blood test (called thromboelastography) that checks how well your blood clots. The goal is to see if this test can predict how the surgery goes and whether you might get a blood clot after surgery. If you join, the test will be done before and after your brain surgery, and you will be monitored for any blood clot complications.
BarcelonaAges 18 years+ - NCT07812883Recruiting
Preserving jawbone after tooth removal
This study tests a technique to preserve the jawbone after a tooth is removed, so there is enough bone left to place a dental implant later. It may help people who need a tooth extraction and want to get a dental implant in the future.
Santiago, Santiago MetropolitanAges 18 years+ - NCT07797647Enrolling by invitation
Platelet-rich bladder injections for overactive bladder
This study is testing if an injection of your own platelet-rich plasma into the bladder can help with overactive bladder. The goal is to find a new treatment option for people who have not found relief from other treatments.
Chongqing, Chongqing MunicipalityAges 18–65 - NCT07792720Recruiting
Platelet-rich fibrin and hyaluronic acid for dental implant healing
This study tests whether adding platelet-rich fibrin (a substance made from your blood that helps healing) and hyaluronic acid (a natural joint and tissue lubricant) to dental implants improves healing. If you need a dental implant in your lower back teeth and are generally healthy, this might help you heal faster and more comfortably.
Sanaa, Sana'aAges 18–65 - NCT06536582Recruiting
Nutrition’s role in PRGF treatment for shoulder tendon pain

Common questions
- Are there clinical trials for platelets?
- Yes. Clin2 currently lists 234 recruiting platelets studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a platelets trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a platelets trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
