Recruiting studies
- NCT05473273Recruiting
Blood test study during normal frozen embryo transfer
This study measures changes in your blood immune markers during frozen embryo transfer when the embryo is chromosomally normal. It may help clinics understand what blood immune patterns relate to successful pregnancy in natural or hormone-prepared cycles.
Abu Dhabi, Abu Dhabi EmirateAges 18–40 - NCT05262010RecruitingPhase 3
HPV vaccine study for Chinese women, ages 9–45
This trial tests an 11-type HPV vaccine to prevent infection from multiple HPV strains. If you enroll, you’ll receive scheduled vaccine doses and have health and gynecologic check-ins to see how well the vaccine works and is tolerated.
Hechi, GuangxiAges 18–45 - NCT05040204RecruitingPhase 1
Test supplements to change how sugars attach to blood proteins
This early (Phase 1) study tests how adding specific dietary supplements affects “protein glycosylation,” which means how sugar molecules attach to proteins in your blood. It’s meant to see how the supplements change these blood measurements and whether the approach is tolerable in generally healthy adults.
Sacramento, CaliforniaAges 18–45 - NCT04968964Recruiting
Monitoring test for CDK4/6 drugs in metastatic breast cancer
This study follows people with hormone receptor–positive, HER2-negative metastatic breast cancer who are taking CDK4/6 inhibitor treatment (with or without an added blood test called DiviTum®). The goal is to see how well the standard treatment is working and whether DiviTum® (a serum TK1 activity test) can help guide monitoring.
St Louis, MissouriAges 18 years+ - NCT04956445Recruiting
Donate blood and mucus samples to study virus treatments
This study collects samples from people who currently have, recently had, or may have been exposed to common respiratory viruses. The goal is to use these samples to develop and test future countermeasures (like treatments) against COVID-19 and other viruses.
New Orleans, LouisianaAges 6 months–120 years - NCT04109131Recruiting
Study platform for brain metastases in solid cancers
This trial studies people with solid tumors that have spread to the brain (including the brain lining) to help researchers learn what works and how best to treat it. You may be asked for blood/tissue samples and a procedure to collect spinal fluid when brain metastases are diagnosed.
AnderlechtAges 18 years+ - NCT04666402Recruiting
Testing better ways to diagnose early liver disease
This study looks at integrated diagnostic tests to find early liver problems sooner. It may help you (if referred to the community liver clinic) get more timely information about what’s going on.
Manchester, Greater ManchesterAges 18 years+ - NCT04669886Recruiting
Blood test before kidney stone surgery to predict infection risk
This study looks at a blood test done before percutaneous nephrolithotomy (PCNL), a procedure to remove kidney stones. The goal is to see whether results can predict who is more likely to develop infections or strong whole-body inflammation after surgery.
Miami, FloridaAges 18 years+ - NCT03974997Recruiting
Blood test to predict multiple sclerosis flare-ups
This study looks at a blood marker called TWEAK to see if it can signal when multiple sclerosis or its first symptoms might flare up again. If you join, your blood would be checked at regular visits to help predict future inflammation.
MarseilleAges 18 years+ - NCT03835767RecruitingPhase 2
Predicting food allergy from blood IgE levels in eczema patients
This study looks for blood test patterns that may predict whether a child with eczema (atopic dermatitis) is likely to have a food allergy. If you join, you may do supervised oral food challenges with a placebo and the suspected foods to see what triggers symptoms.
Bethesda, MarylandAges 3–21 - NCT03359109Enrolling by invitation
Checking metal levels in children with metal implants
This trial studies how much metal can build up in the body and in the blood in children and teens who will receive certain metal implants during surgery. It may help doctors better understand potential metal exposure and how to monitor it.
Rochester, MinnesotaAges 4–18 - NCT02869802Recruiting
Study types of pancreatic cancer using tumor gene testing
This trial studies metastatic pancreatic cancer by taking a small tissue sample and analyzing its genes. It may help doctors better understand which cancer subtypes patients have, which can guide future treatment choices.
Calgary, AlbertaAges 18 years+ - NCT01042548Recruiting
Testing blood and tissue markers in breast surgery patients
This study looks at proteins and imaging patterns (from tissue, fluid near the tumor, and blood) to better understand breast cancer markers. It may help researchers find clues that doctors can use to evaluate breast nodules and newly diagnosed invasive breast cancer.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT00349830Recruiting
Blood marker test to track response to cancer treatment
This study looks for new blood (serum) markers that may show whether anti-cancer therapy is working. If you have cancer or possible cancer and can safely take part, your blood may be used to monitor treatment response over time.
Stanford, CaliforniaAges 18 years+ - NCT00704626Enrolling by invitation
Blood antibody tests in autoimmune brain and nerve diseases
This study looks at blood “auto-antibodies,” which are immune proteins that may attack the body, in people with certain brain and nerve conditions. It may help researchers better understand these diseases and how the immune system is involved.
Sacramento, CaliforniaAges 18 years+ - NCT00026884Recruiting
Blood and tissue sample collection for cancer research
This study collects blood and tissue samples from people with cancer or suspected cancer, or from their blood relatives. Researchers use these samples to better understand cancer and develop new treatments.
Bethesda, MarylandAges 2 years+

Common questions
- Are there clinical trials for serum?
- Yes. Clin2 currently lists 184 recruiting serum 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 serum 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 serum 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.
