Recruiting studies
- NCT04201210RecruitingPhase 2
Stem cell transplant study for young people with severe sickle cell
This Phase 2 study tests a type of stem cell transplant that uses donor immune cells that have been specially “tweaked” to help treat sickle cell disease. It may help prevent serious sickle cell complications, but it requires careful matching and screening of organs and pregnancy status.
ViennaAges 2–35 - NCT06107400RecruitingEarly Phase 1
RM-004 cell therapy for Hemoglobin H-Constant Spring disease
This early-phase trial tests a new cell therapy called RM-004 for people with Hemoglobin H-Constant Spring disease, a form of alpha thalassemia that requires regular blood transfusions. The goal is to see if the treatment is safe and can reduce or eliminate the need for transfusions.
Nanning, GuangxiAges 12–35 - NCT07823569Recruiting
Measuring hemoglobin levels during spine surgery in the prone position
This study tests whether lying face down during spine surgery affects the accuracy of a noninvasive (no needle) hemoglobin monitor. It may help doctors get reliable blood measurements without extra blood draws.
Istanbul, IstanbulAges 18 years+ - NCT06857630Recruiting
Hemoglobin levels and kidney injury in emergency surgery
This trial looks at whether a patient's hemoglobin level (a measure of red blood cells) before emergency surgery can help predict the risk of acute kidney injury afterward. It aims to find if early detection can prevent kidney damage.
SamsunAges 18–80 - NCT06646640Recruiting
Long-term follow-up for hemoglobin disorder treatments
This study tracks people with sickle cell disease or thalassemia who have had a bone marrow transplant or gene therapy in the past 15 years. It aims to monitor their health over time to understand long-term effects.
Memphis, TennesseeAges Any age - NCT06184373Recruiting
Early glucose monitoring after gestational diabetes pilot
This study tests a continuous glucose monitor (a small patch that tracks your blood sugar) for a few weeks after you give birth. It aims to see if this tool can help women who recently had gestational diabetes better understand their blood sugar levels after delivery.
Columbus, OhioAges 18–50 - NCT05977686Recruiting
Hemoglobin testing in pregnant adults
This trial studies how hemoglobin (an oxygen-carrying protein in blood) is checked during pregnancy. It may help improve or confirm the best way to monitor blood health in pregnant patients.
Washington D.C., District of ColumbiaAges 18–50 - NCT05266534Recruiting
Terlipressin or oxytocin during open fibroid surgery
This trial compares two injected medicines (terlipressin vs carbetocin) given into the uterus during open fibroid (myomectomy) surgery to see which one reduces blood loss and helps maintain hemoglobin. It may help patients by targeting lower bleeding during surgery.
MaadiAges 16–40 - NCT07800247Recruiting
Sickle cell disease registry for young patients
This study collects information about children, teens, and young adults with sickle cell disease to better understand the condition in Egypt. It may help improve care and treatments for people with sickle cell disease.
CairoAges Up to 39 years - NCT07743242Recruiting
Study of hemolytic anemia in antiphospholipid syndrome
This study looks at how autoimmune hemolytic anemia (when the body attacks its own red blood cells) relates to antiphospholipid syndrome (a condition that increases blood clot risk). It aims to better understand this connection, which may help improve care for people with both conditions.
Al Khārjah, Kharga OasisAges 18 years+ - NCT07673302Recruiting
Study of drugs to boost fetal hemoglobin in beta thalassemia
This trial tests if certain drugs can safely increase fetal hemoglobin (a type of hemoglobin that helps carry oxygen) in people with beta thalassemia major. It may offer a new way to manage the condition and reduce the need for transfusions.
Rawalpindi, Punjab ProvinceAges Any age - NCT07672275Recruiting
How blood transfusions affect stress markers in newborns
This study looks at how blood transfusions change stress-related substances in the blood of newborns. It might help doctors understand how transfusions affect babies in the NICU.
Graz, StyriaAges 5 minutes–5 months - NCT07621419Recruiting
Semaglutide for Type 2 Diabetes in Real-World Care
This study tests how well a diabetes medication called semaglutide works when prescribed in everyday clinical practice in Argentina. Semaglutide comes in two forms—a pill or an injection—and the study tracks how much it lowers blood sugar over one year.
Buenos Aires, Buenos AiresAges 18 years+ - NCT07445997Recruiting
HbA1c and kidney injury after heart bypass surgery
This study looks at whether blood sugar levels (HbA1c) before surgery are linked to kidney problems after coronary artery bypass surgery. It may help doctors understand how to reduce risks for people with diabetes or high blood sugar.
BursaAges 18 years+ - NCT07416656Recruiting
Checking blood sugar test accuracy for arthritis patients on sulfasalazine
This study checks if the medicine sulfasalazine affects a blood sugar test (HbA1c) in people with inflammatory arthritis. If you have arthritis, take sulfasalazine, and have higher blood sugar or diabetes, this trial may help understand your glucose levels.
Silkeborg, Central JutlandAges 18 years+ - NCT06906835Recruiting
Comparing two blood tests to guide iron treatment in dialysis patients
This trial tests whether a new blood test (reticulocyte hemoglobin) is better than the usual iron test (transferrin saturation) for guiding when to give iron to people on dialysis. If you have anemia (low red blood cells) from kidney disease, this study may help doctors find the best way to treat your iron levels.
Pathumwan, BangkokAges 18–80 - NCT07206095Recruiting
Better diagnosis for inherited red blood cell diseases
This trial aims to improve how doctors diagnose rare inherited anemias, including sickle cell disease and other conditions that destroy red blood cells. It may help if you have a confirmed or suspected diagnosis but need more clarity through advanced testing.
Barcelona, BarcelonaAges Any age - NCT06993805Recruiting
Study to improve A1c and TSH lab orders
This trial tests a new advisory tool to help doctors order A1c and TSH tests more effectively for patients who are staying in the hospital. It aims to reduce unnecessary duplicate lab orders within 30 days.
Los Angeles, CaliforniaAges Any age - NCT06490627RecruitingPhase 2
thalidomide for transfusion-dependent beta thalassemia
This trial tests different doses of thalidomide to see if it can reduce or eliminate the need for blood transfusions in people with beta thalassemia major or intermedia.
Karachi, SindhAges 8–35 - NCT07014501Recruiting
Stroke recovery and trach tube removal at different altitudes
This trial studies how well stroke patients with a breathing tube (tracheostomy) can have it removed. It looks at genes and blood oxygen levels, and compares patients at different altitudes to find the best timing for removal.
Kunming, YunnanAges 18–75 - NCT07015684RecruitingPhase 1
Radioactive antibody and transplant for advanced sickle cell disease
This trial tests a radioactive antibody (131I-apamistamab) as part of conditioning before a stem cell transplant from a matched sibling donor. It aims to make the transplant safer and more effective for people with severe sickle cell disease.
New York, New YorkAges 12–50 - NCT06995378Recruiting

This trial tests if a lifestyle program (diet and activity changes) can help pregnant women who have slightly high blood sugar in early pregnancy. It aims to improve glucose levels and reduce complications for both mother and baby.
Guangzhou, GuangdongAges 18–55 - NCT06718439Recruiting
Comparing blood transfusion levels during and after surgery
This trial tests whether giving blood transfusions sooner or later during surgery affects recovery for patients with low hemoglobin. It compares using a liberal (higher) threshold to give blood versus a more restrictive (lower) threshold.

Common questions
- Are there clinical trials for hemoglobin?
- Yes. Clin2 currently lists 32 recruiting hemoglobin 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 hemoglobin 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 hemoglobin 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.
