BesançonAges 12 years+ - NCT04038619RecruitingPhase 1
Fecal transplant for immune-therapy diarrhea or bowel inflammation
This early-phase study tests whether stool/fecal microbiota transplant (a fecal transplant) can help people who develop significant diarrhea or colitis after immune-checkpoint therapy. It aims to reduce bowel inflammation and improve symptoms, while carefully checking for infections.
Houston, TexasAges 18 years+ - NCT04099797RecruitingPhase 1
CAR T therapy for certain GD2 brain tumors
This Phase 1 study tests CAR T cells designed to target a marker called GD2 on brain tumors. It aims to see if the treatment is safe and whether it can shrink or control these tumors in children and young adults.
Houston, TexasAges 1–25 - NCT04144023RecruitingPhase 1
Vaccine before surgery for HER2-positive breast duct cancer in place
This Phase 1 study tests a vaccine (H2NVAC) given before surgery to help the body fight HER2-expressing ductal carcinoma in situ (DCIS) that has not been removed yet. Because it’s early-stage, the main goal is to check safety and learn how the treatment may work.
Jacksonville, FloridaAges 18 years+ - NCT04113993RecruitingPhase 4
Bazedoxifene study in women with schizophrenia
This trial tests whether bazedoxifene can help women with schizophrenia who are stable on their current medicines. You may be asked to do questionnaires and thinking (cognitive) tests to see if symptoms or brain-related measures change.
Melbourne, VictoriaAges 18–65 - NCT04075305Recruiting
Study measuring radiation treatment outcomes with an MR-Linac
This study follows what happens when radiation treatment is guided using an MR-Linac (a special machine that combines MRI imaging with radiation). It may help improve how radiation therapy is planned and assessed, especially for people who can safely have MRI scans.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04083183RecruitingPhase 1/Phase 2
Testing radiation plus antibody therapy for certain non-cancer diseases
This early-phase study tests a conditioning treatment using total-body irradiation and a radioactive antibody (called astatine-211) before a stem cell transplant for non-cancer conditions. The goal is to improve how well the donor cells take hold and are tolerated.
Seattle, WashingtonAges 18–49 - NCT04049331RecruitingPhase 2
Testosterone therapy for cancer survivors with fatigue
This trial tests whether testosterone replacement can help male cancer survivors who have ongoing fatigue and low testosterone levels. It is for men who have completed chemotherapy or radiation and are cancer-free for at least a year.
Boston, MassachusettsAges 18–54 - NCT04026776RecruitingEarly Phase 1
Study hormones and salt sensitivity in adults born preterm
This early-phase study looks at natural body chemicals (uric acid and klotho) and how sensitive your blood pressure may be to salt. It may help researchers understand long-term health risks in people born very early.
Winston-Salem, North CarolinaAges 22–33 - NCT04144972Recruiting
Closed-loop deep brain stimulation for long-lasting nerve pain
This trial tests a “smart” deep brain stimulation device that senses your brain signals and adjusts treatment to reduce severe, long-lasting pain. It may help people whose pain has not improved with multiple pain medicines and surgery cannot fix the cause.
San Francisco, CaliforniaAges 22–80 - NCT04144907Recruiting
Protein needs study for colorectal or breast cancer
This study tests how much protein people with colorectal or breast cancer need during treatment or recovery. It may help improve nutrition guidance and support for maintaining health during chemo or after surgery.
Edmonton, AlbertaAges 45–80 - NCT04061421RecruitingPhase 1/Phase 2
Testing new medicine combos for bone marrow disease overlap syndromes
This early-phase trial studies a new treatment plan (decitabine-related medicine with other targeted drugs, depending on the arm) for adults with MDS/MPN overlap syndromes. It aims to improve control of the disease by targeting the abnormal bone marrow cells. Because it’s Phase 1/2, the main goal is to find safe dosing and see whether it helps responses.
Tampa, FloridaAges 18 years+ - NCT04141462Recruiting
Genetic testing study for early cancer risk
This study looks at whether DNA (from a tumor or related samples) can help identify inherited cancer risk in people who develop cancer at a young age. It may help families learn more about risk factors and guide future screening or prevention.
BesançonAges 18 years+ - NCT03986021Recruiting
How periods develop in young girls and women

San Francisco, CaliforniaAges 22–70 - NCT03941756Recruiting
Lymph bypass before underarm node surgery to prevent swelling
This study looks at whether adding a lymph “bypass” procedure before underarm lymph node surgery can lower the chance of arm or chest swelling (lymphedema) after cancer treatment. It compares people having lymph node surgery for breast cancer with plans for radiation, and a melanoma comparison group.
Houston, TexasAges 18 years+ - NCT03970096RecruitingPhase 2
Reduce graft-versus-host disease after stem cell transplant
This Phase 2 study tests ways to lower the risk of graft-versus-host disease (GVHD), a serious complication after an allogeneic stem cell transplant from a matched donor. It is for people with acute leukemia or MDS who are going to receive intensive conditioning therapy, aiming to improve safety while keeping the transplant effective.
