Blood sample study for vaccine test development
This study collects blood samples to help researchers develop better tests. It is for healthy people who have not had a pneumococcal vaccine before.
Adelaide, South AustraliaAges 18–69 - NCT07216430RecruitingPhase 2
Safety and efficacy of a pneumococcal vaccine in young kids
This study tests a new pneumococcal vaccine (wSp) in young children who have already had 3 doses of a standard pneumococcal shot. It aims to see if the new vaccine is safe and works well to protect against serious infections.
Pittsford, New YorkAges 5 months–7 months - NCT07680413Recruiting
Study of Histoglob for chronic hives in real-life care
This trial is looking at how well the drug Histoglob (Immunoglobulin-Histamine Complex) works for people with chronic urticaria (hives that last a long time). It's for patients who are already on a first-line treatment and are starting Histoglob for the first time as part of their regular care.
Ahmedabad, GujaratAges 13 years+ - NCT07251036Recruiting
Chordecone levels in Guadeloupe: support program impact
This study measures chordecone levels in people living in Guadeloupe. It tests whether a support program can help lower contamination over time.
Pointe-à-Pitre, GuadeloupeAges 18 years+ - NCT07263061Recruiting
Recovery of albumin after major liver and pancreas surgery
This trial tracks how quickly your albumin (a protein in your blood) returns to normal after major surgery on your liver, pancreas, or bile ducts, to see if that predicts your recovery. It may help doctors understand how you are healing.
New Delhi, National Capital Territory of DelhiAges 13–80 - NCT07353216Recruiting
Testing ofatumumab for relapsing multiple sclerosis
This trial tests if ofatumumab can help people with relapsing multiple sclerosis (RMS) by measuring its effect on nerve damage markers in the blood. It aims to see if the drug is safe and effective for controlling relapses and slowing disease activity.
Guangzhou, GuangdongAges 18 years+ - NCT07358754Recruiting
S100B and BDNF levels in fibromyalgia
This trial measures two brain-related proteins (S100B and BDNF) in women with fibromyalgia compared to healthy women. It aims to find out if these proteins are linked to fibromyalgia symptoms, which could lead to better understanding or new treatments.
IstanbulAges 18–50 - 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+ - 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+ - 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.

Test blood markers to help diagnose metastatic uveal melanoma
This study checks whether blood “biomarkers” (measurable signs in serum) can help diagnose metastatic uveal melanoma. If you have uveal melanoma, the study may look at how useful these blood tests are for spotting spread to other parts of the body.
JerusalemAges Any age - NCT01372800Recruiting
Study blood adiponectin levels and stroke/heart risk
This study measures a blood marker called adiponectin and looks at how it relates to heart and stroke (cardiovascular and cerebrovascular) problems over time. It may help doctors understand who is at higher risk, especially in Chinese participants.

Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.

Common questions
- Are there clinical trials for serum?
- Yes. Clin2 currently lists 190 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.
