- NCT05213572Recruiting
Deep health check study for adults with sickle cell disease
This study looks at how major organs like the brain, kidneys, heart, and liver are affected in adults with sickle cell disease, whether they've had a bone marrow transplant or gene therapy, or are continuing regular treatment. You'll get detailed tests that can help doctors understand the disease better, which may lead to improved care.
Bethesda, MarylandAges 18–100 - NCT07282210RecruitingPhase 2
New medicine for sickle cell hemolysis
This trial tests a new medicine (SIL-8301) to help control red blood cell breakdown (hemolysis) in people with sickle cell disease. It is for those who are already taking hydroxyurea and have had few pain crises but still have complications from hemolysis.
Toronto, OntarioAges 16–35 - NCT03685721Recruiting
Study genes in sickle cell disease to compare blood test activity
This study looks at how a person’s genes relate to certain measurements in red blood cells in people with sickle cell disease. The goal is to understand why blood cell function varies and how that might guide future care.
Bethesda, MarylandAges 18–80 - NCT07616154RecruitingPhase 2
Gene-Matched Family Stem Cell Transplant for Severe Sickle Cell
This trial tests whether a stem cell transplant from a partially gene-matched family member can cure severe sickle cell disease in children and young adults. The transplant uses a new approach that may work even when a perfectly matched sibling isn't available, and it might help patients whose sickle cell is causing serious complications like strokes, organ damage, or frequent pain crises.
Memphis, TennesseeAges Up to 22 years - NCT07708714RecruitingPhase 1/Phase 2
Hydroxyurea study for teens with sickle cell anemia
This study tests how well a higher dose of hydroxyurea works for teenagers with sickle cell anemia living in areas where malaria is common. It looks at safety and how the treatment affects their daily lives.
KampalaAges 11–18 - NCT06016634RecruitingPhase 2
Alendronate for bone damage in adults with sickle cell disease
This trial tests if the drug alendronate can help heal bone damage caused by sickle cell disease. It may be an option if you have this bone problem and are between 18 and 80 years old.
Sacramento, CaliforniaAges 18–80 - NCT03279094RecruitingPhase 1
Testing a half-matched bone marrow transplant for sickle cell
This early-phase study tests whether a “half-matched” donor bone marrow transplant, with special medicines to calm the immune system before transplant, can improve outcomes for people with sickle cell disease. It may help high-risk patients who have frequent complications and don’t have a fully matched donor.
Duarte, CaliforniaAges 1–30 - 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 - NCT04774536RecruitingPhase 1/Phase 2
CRISPR gene-edited bone marrow transplant for severe sickle cell
This Phase 1/2 study tests a CRISPR-edited bone marrow (stem cell) transplant to treat severe sickle cell disease. It aims to reduce dangerous sickle-related complications by changing the patient’s stem cells before transplant.
Los Angeles, CaliforniaAges 12–35 - NCT07599176RecruitingPhase 1/Phase 2
Partial stem cell transplant for sickle cell disease from matched donors
This study tests a partial stem cell transplant from a matched donor to treat sickle cell disease. It may help reduce complications like strokes, organ damage, or pain crises.
Bethesda, MarylandAges 4–65 - NCT05392894RecruitingPhase 3
Transplant using a half-matched donor for severe sickle cell
This trial tests whether a half-matched (haploidentical) blood stem cell transplant can treat adults with severe sickle cell disease. It may help reduce serious complications and improve survival, but it requires a fit health status and specific donor and medical conditions.
LondonAges 18 years+ - NCT05477563RecruitingPhase 3
One-time gene therapy for severe sickle cell and transfusion anemia
This trial tests a single dose of gene therapy (CTX001) to improve outcomes for people with severe sickle cell disease or transfusion-dependent beta-thalassemia. It aims to see how well it works and whether it is safe, especially after a planned stem cell transplant process.
New York, New YorkAges 12–35 - NCT05904093RecruitingPhase 1
Check if increasing fostamatinib doses are safe in sickle cell
This Phase 1 study tests whether increasing doses of fostamatinib are safe and tolerated in adults with stable sickle cell disease. It may help researchers understand if the drug could be a future treatment option for people with stable sickle cell.
Bethesda, MarylandAges 18–65 - NCT06071377Recruiting
Learning About Health in People With Sickle Cell Trait
This study is for adults who have or might have sickle cell trait (carrying the sickle cell gene but not the disease). It aims to understand the health effects of sickle cell trait over time by following participants and collecting health information.
Birmingham, AlabamaAges 18 years+ - NCT06184126Recruiting
Virtual reality for sickle cell pain in the emergency room
This trial tests whether using a virtual reality (VR) headset, along with your usual pain treatment, can help reduce pain during a sickle cell crisis. It is for adults with sickle cell disease who are in the emergency department and receiving IV opioids for a vaso-occlusive crisis.
Baltimore, MarylandAges 18 years+ - NCT06399107RecruitingPhase 1/Phase 2
Gene therapy trial for sickle cell disease using BAH243
This trial tests a gene therapy that uses a modified virus to deliver a healthy gene to your blood stem cells. It aims to help people with sickle cell disease produce normal red blood cells and reduce painful crises.
Beijing, Beijing MunicipalityAges 2–90 - NCT06506461RecruitingPhase 1
Gene editing for sickle cell disease in young adults
This trial uses gene editing to fix your own blood stem cells, so you can stop having severe sickle cell crises. It is for young adults with frequent pain episodes or who need regular blood transfusions.
Memphis, TennesseeAges 18–24 - NCT03121001RecruitingPhase 2
Transplant from a half-matched donor for aggressive sickle cell
This Phase 2 study tests a “half-matched” stem cell transplant to treat people with aggressive sickle cell disease. It may help by replacing the blood system using stem cells from a related donor who is close but not fully matched.
Chicago, IllinoisAges 16–60 - NCT06647979RecruitingPhase 1
Gene editing for severe sickle cell or thalassemia
This trial tests a new gene therapy that edits your own blood stem cells to help them make more fetal hemoglobin, which can prevent sickling and reduce the need for transfusions. It is for people with severe sickle cell disease or beta thalassemia who do not have a matched sibling donor.
Boston, MassachusettsAges 13–40 - NCT06665997RecruitingPhase 4
Depot shot for pain in women with sickle cell disease
This study tests if a hormone shot (depot medroxyprogesterone acetate) can help reduce pain episodes in women with sickle cell disease. It aims to see if the shot improves pain and markers of inflammation.
Atlanta, GeorgiaAges 18–50 - NCT06941389Recruiting
Comparing stem cell transplant vs standard therapy for sickle cell disease
This study compares two treatment approaches for children with sickle cell anemia: a stem cell transplant from a matched family donor versus continuing regular disease-modifying medicines. It aims to see which treatment works better over time.
Birmingham, AlabamaAges 3–20 - NCT07001189Recruiting
Numbing for sickle cell pain crisis: a study
This trial tests whether numbing a specific area (regional anesthesia) can reduce inflammation and pain during a sickle cell pain crisis. It may offer a new way to manage severe pain without strong medications.
Pointe-à-PitreAges 18 years+ - NCT07064174Recruiting
Sickle cell kidney research study
This study collects kidney tissue samples from people with sickle cell disease and healthy volunteers to better understand how sickle cell affects the kidneys. If you have sickle cell disease or a related blood disorder, you may help researchers find new ways to protect kidney function.
Dallas, TexasAges 18–65 - NCT07083531Recruiting
Bone health study for older Black women with sickle cell trait
This study looks at how carrying the sickle cell trait (not the disease) affects bone density, physical function, and frailty in older African American women. It aims to help understand bone loss risk and prevent fractures.
